The following are several key points in this poorly designed and biased study:
1. The possibility of false positive reactions on the “HIV test” was not considered.
This study leads the reader to conclude that the detection of antibodies against what are supposed to be HIV antigens in saliva by an ELISA test is synonymous with HIV infection and that the only reason for reacting positively on the so-called tests for HIV is infection with HIV. In this regard the report states: “The HIV test used in this study, as with all ELISA HIV tests, detects the presence of HIV antibodies in the oral fluid of the participant. Over 99% of people over the age of two years and who are infected with HIV will test positive on the ELISA because almost all PLWHA produce HIV antibodies” (page 32).
The report states: “The sensitivity and specificity of the OraSure device when tested with the Vironostika EIA is 99% and also 99% according to the manufacturers (Gallo et al. 1997)” (page22). However, the report does not explain how the sensitivity and the specificity were determined.
The laboratory used in this study, at the University of Natal Durban, “recently did a comparison of sensitivity and specificity of HIV testing on saliva versus serum specimens (Perumal 1999). Paired saliva and serum specimens from 500 individuals were tested using ELISAs, and positive serum specimens were confirmed using Western Blot. The sensitivity and the specificity of the saliva tests were 100% and 99.3% respectively” (page 43). How could they be certain that the saliva test was 99.3% specific for a virus named HIV? The report did not explain this crucial matter.
In the “reliability of the HIV test results” section, the study explains in detail the different negative and positive internal as well as external controls used every time the test was run at the three laboratories chosen for it. Then the study states: “In conclusion, quality control clearly confirms the validity of HIV results obtained in this study” (page 45). However, it is a regular clinical laboratory practice to run controls with known results each time a test is run to be sure that the test is working. The fact that the test works does not mean that the test is valid or specific to detect infection with HIV.
Researchers and other designers of this study considered false positive tests only after they excluded children under two years of age because “the infant may not be actually infected with HIV him or herself but may, if the mother was HIV infected, still be carrying the mother's antibodies. The child will therefore test positive on the ELISA test even though he/she is not infected (false positive test)” (page 32).
It is internationally known that “HIV antibody tests” are inaccurate, which is why, in countries such as the USA, the law requires that a person have 4 ELISA tests be positive and one Western blot test be positive before he or she is declared to be “HIV positive.” However, in the present survey only one ELISA test was run on saliva. The insert included with the kit used to conduct one of the more popular ELISA tests for “HIV” warns: “At present there is no recognized standard for establishing the presence or absence of antibodies to HIV-1 and HIV-2 in human blood” (Abbott 1996).
The scientific literature shows that there are more than 70 known human conditions that can produce false positive results on so-called tests for HIV. Most of these conditions are common to the African scenario. Some of them are: past or present infection with a variety of bacteria, parasites, viruses, and fungi including tuberculosis, malaria, leishmaniasis, influenza, the common cold, leprosy and a history of sexually transmitted diseases; the presence of polyspecific antibodies, hypergammaglobulinemias, the presence of autoantibodies against a variety of cells and tissues, vaccinations, and the administration of gammaglobulins or immunoglobulins; the presence of autoimmune diseases like erythematous systemic lupus, sclerodermia, dermatomyositis and rheumatoid arthritis; the existence of pregnancy and multiparity; a history of rectal insemination; addiction to recreational drugs; several kidney diseases, renal failure and hemodialysis; a history of organ transplantation; presence of a variety of tumors and cancer chemotherapy; many liver diseases including alcoholic liver disease; hemophilia, blood transfusions and the administration of coagulation factors. This is only a partial list (Johnson 1996; Giraldo et al 1999). Unfortunately, researchers and institutions responsible for this survey ignored these facts.
The questionnaires designed for this survey did not record data regarding past medical history of the participants. This could have helped to determine if participants had current or past conditions that could cause “tests for HIV” to react positively, without the person being actually infected with HIV.
For a detailed analysis of the problems with “HIV tests” see my article: “Tests for HIV are highly inaccurate”, in APPENDIX A of this document.
2. Prevalence of HIV infection or prevalence of reactivity to an “HIV test” in saliva.
One of the main goals of this study was to “determine HIV prevalence in a population of South Africa using linked anonymous HIV saliva tests” (page 9).
All ELISA and Western blot HIV tests, including the Vironostika test kit used in this study, are merely tests to detect the presence of what are supposed to be HIV antibodies. They do not detect infection with HIV. None of these tests can be used to make a diagnosis of HIV infection or AIDS. Therefore, neither of these tests can determine the prevalence of HIV infection.
The only conclusion to be drawn from this study is that a sampling of South Africans demonstrate antibodies against what is believed to be HIV antigens in saliva.
Therefore, this study cannot be interpreted as a “nationwide community-based survey of the prevalence of HIV in South Africa,” as stated by Dr. Orkin in the Preface.
After
describing “HIV prevalence” for all races, the
study states: “people living with HIV/AIDS are found in every
race group in South Africa” (page 46). Here the study goes even
further in leading readers to believe that people who react
positively on this ELISA test are infected with HIV or have AIDS.
However, it is internationally recognized that none of the so-called
HIV tests can diagnose HIV infection or AIDS (see APPENDIX A).
Although this survey cannot be used as a measure of the prevalence of HIV infection in South Africa, it does include some interesting data. Examples include:
The overall prevalence of reacting positively on an ELISA test “for HIV” in saliva was found to be 11.4%, much lower than expected by researchers (20%) or has been estimated by International institutions like UNAIDS.
According to data reported in this study, the main risk factor for reacting positively on the saliva “HIV test” are as follows: being African (12.9%), being female (12.8%), living in urban areas, especially if these are informal (21.3%), being poor, and having had sexually transmitted infections (summary in page 57). It is important to note that a common denominator to all of these conditions is poverty and its consequences.
It will be crucial to investigate in the next survey all potential risk factors (immunological stressors) that cause Africans, women, people living in urban informal areas, persons who are poor, and those who have had sexually transmitted infections to react more positively than others on the ELISA saliva test (page 57).
The report states: “Although Africans have the highest estimated HIV prevalence, whites and coloureds also have high estimated prevalence. The estimated HIV prevalence among whites in South Africa is much higher than that observed in predominantly white societies, for example in the USA, Australia, France and UK, which have HIV prevalence less than 1% (UNAIDS 2002)” (page 59). This means that the very fact of living in South Africa is a risk factor for reacting positively on this ELISA test, even for white people.
“HIV prevalence derived from antenatal data: This study calculated the HIV prevalence among women who reported being pregnant in the 12 months before the study (n=244) and found that 24% (CI: 15.8-34.8%) were HIV positive, a finding similar to the Department of Health's survey of clinics, which found 24.8%” (page 59). However, 24% ELISA reactivity in pregnant women doubles the national average of 11.4% found for all South Africans and that of 12.8% found for women in this study. The high percentage of reactivity on ELISA tests found in pregnant women by both this study and the Department of Health's surveys can be explained due to the fact that pregnancy and multiparity are known risk factors for reacting positively on antibody tests “for HIV” (appendix A).
Unfortunately, several important groups of people were excluded from this survey: infants less than 2 years, homeless people, soldiers, prisoners, and students living in boarding schools (page 31). Additionally, several groups of particular interest for the understanding of the AIDS epidemic were not captured in sufficient numbers in this survey: homosexual and bisexual men, drug abusers, and sex workers (page 31).
3. Poverty was not properly addressed.It is not true that: “This is the first South African study that systematically investigates the socio-cultural, political, economic and structural context within which HIV-related behavior occurs” (page 30), since this study did not properly investigate the economic status of South Africans that participated in it. The report acknowledges this: “While this study cannot claim to have adequately measured poverty, a perceived rating of adequacy of household income was utilized as a measure” (page 62).
Researchers and institutions responsible for this study knew of the importance of poverty: “It is widely acknowledged that poverty plays a pivotal role in increasing vulnerability to HIV infection in sub-Saharan countries including South Africa” (page 4). However, in this study they did not address poverty properly.
Although the matter of poverty was not properly addressed, this study does include interesting data:
The report states: “Wealthy Africans have similar levels of risk as less wealthy Africans. However, in the other race groups, lower socio-economic status appears to be related to higher likelihood of HIV infection, even after multivariate adjustment. Further work is required to create an index of poverty comprising detailed employment categories such as work in informal sector, formal sector, part-time employment, occupation, and sources of income. This might shed more light on the relationship between HIV and poverty” (page 63).
Regarding socio-economic status, the report states: “there is a decrease in HIV prevalence from the poorer to richer homes when all participants are included. This means there is a negative correlation between HIV and socio-economic status. However, this trend disappears when only Africans are considered, as in this group there is no discernable trend” (page 54, Table 23). This means that people living in poverty conditions are more exposed to the factors that make this ELISA test react positively, and that being African, regardless if rich or poor, they are more exposed to the factors that make this ELISA test react positively. We need to recall that Africans, during Apartheid, were subjected to the worst of living conditions and that it will take time to correct these conditions. It is therefore possible to postulate that among the effects being detected in South Africa by the so-called “tests for HIV” are the consequences of Apartheid.
It is interesting that “the two provinces with highest HIV prevalence also have the highest proportion of persons living in urban informal areas. These are Gauteng (19.9%) and Free State (16.9%)” (page 62).
Regarding sexually transmitted infections, the report states: “Table 25 displays HIV prevalence by history of sexually transmitted infections and shows that despite the relatively low reporting levels, there is a strong association between HIV and STDs”, and “there was a significantly higher prevalence of STIs among those living in informal areas” (page 55).
The report states: “Whether or not the STI epidemic is driving the HIV epidemic or whether it is piggybacking on the same risk factors cannot be established from this survey” (page 60). It is scientifically known that all infectious diseases, including sexually transmitted ones, deteriorate the immune system (Ware & Kline 1996). The finding reported in this section could be interpreted as follows: Poverty brings malnutrition and immunedeficiency which make individuals more prone to infections, including sexually transmitted ones, and this deteriorates and oxidizes the immune system, which can be reflected in reacting positively on the ELISA/saliva test used in this survey (Giraldo 1997a,b; Giraldo et al. 1999).
I completely agree with one of the conclusions of this study: “establishing poverty alleviation projects to address the root causes of HIV/AIDS, STIs and TB” (page 105).
4. Nutritional status was not included.
One of the largest gaps in this study is that it did not investigate the nutritional status of participants.
It is difficult to understand why the researchers and institutions responsible for this survey ignored the fact that, since the beginning of the AIDS epidemic, there has been a growing number of scientific indices supporting the possibility that AIDS can be effectively prevented, treated, and overcome by guaranteeing an optimal nutritional status to individuals that react positively on “tests for HIV” or who have the clinical manifestations of AIDS (Kiure, Msamanga & Fawzi 2002).
It would have been straightforward and useful to have included queries regarding nutrition on the questionnaires and to have evaluated, inexpensively, aspects of the nutritional status of the participants. There will be no excuse for not doing this on the next survey. I would be happy to assist the designers of the next survey in these matters.
For a detailed description of this issue see my article: “The role of nutrition in improving the health of people living with HIV/AIDS”, presented on November 28, 2002 in Johannesburg at a meeting on “Nutrition and HIV/AIDS” organized by the Health Unit of the Southern African Development Community (SADC) (see appendix B).
5. Alternative explanation for 5.6 % reactivity on the saliva “HIV test” of children 2-14 years of age.
“The observation that the estimated HIV prevalence among children aged 2-14 years is 5.6% was unexpected.” “It remains unclear as to how these children could have been infected. An emerging theory that warrants further investigation is that there is unexplained HIV prevalence in children who have had no sexual exposure, or have parents with HIV negative mothers.” “Possible factors to be investigated include sexual abuse and unsterile needles” (page 63).
There is the possibility that these children react positively on the ELISA saliva “HIV test” used in this study because they have been exposed to multiple, variable, and chronic immunological stressor challenges. It is possible that, instead of being infected, they are simply intoxicated or oxidized due to malnutrition, infections, parasites and other consequences of poverty (Giraldo 1997a,b; Giraldo et al 1999). People from this age group deserve special attention on the next survey.
6. Exaggerated focusing on sexual behavior.
This study is highly influenced by the attitudes and beliefs toward HIV/AIDS of the researchers and institutions that designed the survey. This explains why the main focus was on sexual behavior.
The Conceptual Framework, described on page 10, seems to indicate that the only reason for reacting positively on so-called “tests for HIV” is getting “HIV” through sexual activity: “The conceptual framework that informs this study is the second-generation surveillance system, designed by the World Health Organization, UNAIDS and Family Health International. This framework is based on surveys of Knowledge-Attitudes-Beliefs and Practices in relation to sexual behaviors and HIV infection that have been carried out worldwide during the past 15 years” (page 10).
The report demonstrates that, contrary to what has been suggested by Western HIV/AIDS researchers, institutions, and the media, South Africans are not promiscuous at all: “With regard to polygamy, only 3.4% of those who were married (both male and female) reported that they were in a polygamus relationship” (page 77); “When asked if they practiced anal sex, only 2.2% of the 4280 participants who responded to the question answered affirmatively” (page 77); “the median age of sexual debut was 18 years of age for both sexes” (page 78); “Concerning levels of sexual activity, very low levels were reported among children in the 12-14 year age group, and relatively low levels (25%) amongst 15-17 year old youth” (page 78); “sexual frequency amongst sexually active youth is quite low, with the majority of youth (70%) having sex four or less times a month, and 29% having no sex at all” (page 79).
Furthermore, according to this study, South Africans do use condoms: “The levels of condom use of 57% and 46.1% amongst male and female youth respectively are encouraging” (page 79).
This survey demonstrats once again that the issue of sexual behavior has very little or nothing to do with AIDS. Africans need to stand up and demand of the international institutions dealing with AIDS and the media that they cease placing blame on the sexual behavior of Africans.
7. Male circumcision and “sexual transmission of HIV.”
“Research into the influence of male circumcision on the spread of HIV infection has suggested that the practice protects people from HIV infection” (Page 4).
The hypothesis that circumcision can prevent the spread of AIDS has never been scientifically validated. It is merely an assumption based on racial, religious, and sexual prejudices. For a detailed description of this issue see my article: “Circumcision and AIDS in Africa” (appendix C).
The queries regarding circumcision in the questionnaires of this survey are completely unfocused and only serve to increment the stigma concerning AIDS.
I am convinced that Africans will continue questioning and rejecting ethnic fictions and racial slanders. They are already actively defending their integrity.
8. Mother to child “transmission of HIV” (MTCT).“Children under two years were excluded by the protocol of this study” (page 32).
The hypothesis that mothers can transmit HIV or AIDS to their babies during pregnancy, at birth, or by breastfeeding their infants, has never been scientifically validated. For a detailed description of this issue see my article: “The origin of the ‘transmission' of AIDS” (appendix D).
Therefore, the questions regarding what is known as MTCT in the questionnaires are completely unfocused, are misleading, and increment the stigma concerning AIDS.
9. Breastfeeding and “transmission of HIV.”
The questions regarding breastfeeding and the transmission of AIDS in the questionnaires of this survey are also completely unfocused, are misleading and increment the stigma concerning AIDS.
“Issues related to transmission of HIV via blood, PMTCT, and post-exposure prophylaxis were not closely assessed in this study. However, knowledge of HIV transmission via breastfeeding was poor and this should be emphasized in relation to PMTCT interventions” (page 105). Which means that, even though there is no scientific evidence that HIV or AIDS can be transmitted by breast milk, the researchers and institutions responsible for this survey continue to insist that this be included in future surveys.
For a better understanding of this crucial matter having to do with the survival of future generations of Africans, see my article: “Breastfeeding and AIDS in Africa” (appendix E).
10. Promotion of HIV testing.
46.4% of participants 15-24 yeas of age and 35.9% of those 25-49 responded affirmatively to the question “If you do not know your HIV status would you consider going for an HIV test?” (page 99).
This question is a way of promoting HIV testing and making people believe that these tests can really diagnose HIV infection and AIDS, when in reality they cannot.
Promoting HIV testing without explaining the inaccuracy of the tests will raise fears about AIDS and promote sexual stigmatization of the South African community.
How can the researchers and institutions responsible for this survey state: “Awareness of VCT [voluntary counseling and testing] services is relatively low”; when “one in five South Africans had had an HIV test” (page 104). This is typical of the language used by pharmaceutical companies when they want to test everyone for “HIV” and then advise them to take toxic antiretrovirals, alleging that they are thereby preventing the development of AIDS in those who react positively on “tests for HIV” (appendix A).
11. Promotion of antiretroviral medications.
96.5% of participants aged 15 and older responded affirmativly to the question: “Should government provide antiretroviral medications for preventing mother to child transmission of HIV/AIDS” (page 91).
95% of participants aged 15 and older responded affirmativly to the question: “Should government provide antiretroviral medications for those with HIV/AIDS-related illness” (page 91).
These types of questions, by their very nature, suggest certain answers and thus cannot provide objective information. In like manner, there is little objectivity in stating: “The fact that the overwhelming majority of people of all races believe that the government should provide ARVs to prevent transmission of HIV from mother to child and also to treat people living with HIV/AIDS, demonstrates the high level of awareness of South Africans on this issue” (page 92).
The types of queries posed concerning antiretroviral medications in the survey's questionnaires, apart from lacking objectivity, are misleading to the public in that they lead participants to believe that there exists no other solution for preventing and treating AIDS, other than the toxic ARVs. For a detailed description of this issue see my article: “Antiretrovirals can cause AIDS” (appendix F).
Appendix B describes the role of nutritional therapy in HIV/AIDS, which is only one example of a nontoxic, effective, and inexpensive alternative for the prevention and treatment of AIDS.
12. Media and public HIV/AIDS beliefs.
75.7% of adult (15 years+) participants in this study believe that “HIV causes AIDS”; 53.2% believe that “a baby can become HIV positive through breastfeeding”; 11.1% believe that “HIV can be transmitted by kissing”; 4.2% believe that “AIDS can be caused by witchcraft”; 5.1% believe that “HIV can be transmitted by touch”; and only 1.6% believe that “AIDS can be cured by sex with a virgin” (page 82).
These percentages lead to the interpretation that South Africans hold beliefs about AIDS similar to those in most of the countries on Earth and would seem to indicate that the media in South Africa is concentrating its reporting on the HIV/AIDS hypothesis. However, media professionalism requires objective coverage of all sides of a historical controversy, especially when human health is implicated.
13. Conclusions.
“It is vital to have accurate data and a comprehensive understanding of the [AIDS] epidemic” (page 101). Regrettably, I am afraid that this study does not provide this.
It is true, as Nelson Mandela states in the foreword to this study, that: “We have to manage the disease, or the disease will manage us.” We need to understand all of the many facets of AIDS, excluding no possibility, not even those far from or even antagonistic to the widely accepted knowledge and beliefs concerning AIDS. Otherwise, indeed, “the disease will manage us.”
It makes little sense for Nelson Mandela to be promoting HIV testing and antiretroviral medications, since he may well have been introduced to information regarding the inaccuracy of the tests for HIV and the high toxicity of antiretroviral medications, unless he is pursuing some hidden personal agenda. Upon studying the critical analysis provided in this paper, he may come to understand that the Nelson Mandela Foundation's study does not provide “the data to tackle the epidemic [of AIDS] more vigorously.”
“60 million people worldwide have lived with HIV/AIDS since the beginning of the epidemic and 20 million of these have died (UNAIDS 2002). HIV/AIDS now affects every country in the world. Despite advances in knowledge about HIV prevention, the disease continues to spread” (page 1). If this is true, and everything indicates that it is, then public health officials, epidemiologists and researchers need to look at alternative explanations for the causation, prevention, and treatment of AIDS.
The study contains so many “leaps of faith” that it should be used as a negative example for the teaching of epidemiology.
Include on the next survey an evaluation of the nutritional and antioxidant deficiencies of participants.
Include in the next survey a serious evaluation of the income of the participants. According to the data reported in this study, the primary risk factor for reacting positively on the saliva “HIV test” are as follows; being African (12.9%), being female (12.8%), living in urban areas especially if these are informal (21.3%), being poor, and having had sexually transmitted infections (summary in page 57). It is important to notice that a common denominator in all of these conditions is poverty and its consequences.
Include in the next survey an evaluation of all potential risk factors (immunological stressors) that make Africans, women, people living in urban informal areas, people who are poor, or people who had STIs, more likely than others to react positively on the ELISA (Giraldo 1997a,b; Giraldo et al. 1999).
Stop promoting HIV tests for the diagnosis of HIV or AIDS, since they simply cannot do that.
Stop promoting antiretroviral medications and instead promote nontoxic, effective, and inexpensive alternatives for the treatment and prevention of AIDS.
Stop promoting stigmatization about the sexual behavior of Africans. AIDS in Africa cannot be explained by vertical or sexual transmission (Gisselquist et al. 2002).

Tests for HIV are highly inaccurate
By Roberto Giraldo, June 2000
For the last 6 years I have been working at a laboratory of clinical immunology and molecular diagnosis in one of the most prestigious university hospitals in New York City. Here I have had the opportunity to personally run and get to know in detail the current tests used for the diagnosis of HIV status, namely, the ELISA, Western blot and Viral Load tests.
1. The ELISA, Western blot, and Viral Load tests, used for the diagnosis of "HIV infection" are not at all accurate
There are many arguments against the accuracy of the tests used diagnose infection by what is known as HIV. For those who want to research the issue more deeply I strongly recommend beginning with the study of a 1993 article in Bio/Technology by Eleni Papadopulos-Eleopulos and her group of researchers from Perth, Western Australia (12).
Below are some of the facts supporting the proposition that a person who reacts positively on these tests is not necessarily infected with HIV:
1.1. The definition of AIDS, as developed by the United States Federal Government's Centers for Disease Control and Prevention, requires a positive result on the antibody test for HIV (1). This definition is accepted worldwide. The importance of HIV in this definition is so strong that, currently, many AIDS researchers, health care professionals, and lay people, following the lead of the United States' Institutes of Medicine, the National Academy of Sciences, and most AIDS researchers, now refer to "AIDS" as "HIV Disease" (2-7).
However, AIDS in Africa can be diagnosed without HIV tests or any other laboratory tests. This was decided by American public health officials at a conference in Bangui, in the Central African Republic, in October 1985 (WHO's Weekly Epidemiological Record 1986; 61:69-76 and Science magazine 21 November 1986). This permits health professionals to diagnosis AIDS in Africa based solely upon the symptoms and signs that a patient manifests.
1.2. The tests that are used most frequently to diagnose HIV status are the ELISA "screening test," the Western blot "confirmatory test," and the PCR "Viral Load test" (8-11). In the United States the ELISA and Western blot tests, when done together, have become known as "the AIDS test." These tests supposedly detect antibodies against HIV. The "Viral Load" or PCR test is a genetic test that makes copies of small fragments of nucleic acids that, it is claimed, belong exclusively to HIV. These are the same tests that are used to confirm HIV in mothers, infants, children, and in the population at large. The problem with all of these tests is that a positive HIV reaction does not guarantee that the person is really infected with HIV (12-21).
1.3. Currently, a positive result on "the AIDS test" — ELISA and Western blot antibody tests — is synonymous with HIV infection and the attendant risk of developing AIDS (8-11).
However, these antibody tests are neither standardized nor reproducible. With respect to HIV they are meaningless because they are interpreted differently for different individuals, and are interpreted variously in different laboratories and in different countries (12). Test interpretations vary across the United States, Russia, Canada, Australia, Africa, Europe, and South America (22-27), meaning, for instance, that a person who is positive in Africa can be negative when tested in Australia, or a person who is negative in Canada can become positive when tested in Africa (28). Additionally, a given sample of blood, when tested in 19 different laboratories, will produce 19 different results on the Western blot test (29).
1.4. The Western blot antigens, proteins, or bands — p120, p41, p32, p24/25, p17/18 — which are considered to be specific to HIV, may not be encoded by the HIV genome but may in fact represent human cellular proteins (12-14,20,30).
1.5. The only valid method for establishing the sensitivity and the specificity of a diagnostic test in clinical medicine is to compare the test in question with its “gold standard.” The only possible gold standard for the HIV tests is the human immunodeficiency virus itself. Since HIV has never been isolated as an independent, free, and purified viral entity (31), it is not possible to properly define the sensitivity or the specificity of any of the tests for HIV (12). Currently, the sensitivity and the specificity of the tests for HIV are defined not by comparison to purified HIV itself, but through a comparison of the tests in question with the clinical manifestations of AIDS, or with T4 cell counts (12). The Abbott corporation, a test kit manufacturer, states: "At present there is no recognized standard for establishing the presence or absence of HIV-1 antibody in human blood. Therefore sensitivity was computed based on the clinical diagnosis of AIDS and specificity based on random donors" (32). Since there is no gold standard for defining the specificity of the tests used for the diagnosis of HIV infection, all HIV-positive results must be considered false-positives.
1.6. There are numerous scientific publications documenting the more than 70 different conditions that can cause the antibody tests to react positively in the absence of any actual HIV infection (12-14,17,19,30). In other words, there are more than 70 scientifically acknowledged reasons for false positives when testing for HIV. This fact has been abundantly documented in the scientific literature.
1.7. It is, of course, shocking to find that a diagnosis of HIV infection can be based upon tests that are not specific for HIV. However, the scientific evidence tells us that a person can react positively on the tests for HIV even though he or she is not infected with HIV (12-14,17,21,30,33).
1.8. The pharmaceutical companies that make and commercialize the kits for these tests acknowledge the inaccuracy of them, and the inserts that come with the kits typically state the following: "Elisa testing alone cannot be used to diagnose AIDS, even if the recommended investigation of reactive specimens suggests a high probability that the antibody to HIV-1 is present" (32). The insert for one of the kits for administering the Western blot warns: "Do not use this kit as the sole basis of diagnosis of HIV-1 infection" (34). The insert that comes with a popular kit to run viral load warns: "The amplicor HIV-1 Monitor test is not intended to be used as a screening test for HIV or as a diagnostic test to confirm the presence of HIV infection" (35). The difficulty is that most AIDS researchers, journalists, lay people, and health care workers themselves are unaware of these facts concerning the tests because they do not have access to the test kit inserts. Additionally, there appears to be little or no concern on the part of knowledgeable institute faculty to communicate these facts to physicians, let alone to the general public.
1.9. Since viral load results are given in copies per ml of plasma (35), AIDS researchers, health care professionals, and lay people believe that theses numbers represent copies or counts of the virus itself (12,36-41). However, the viral load test only makes copies of fragments of nucleic acids. It does not count HIV itself. A positive viral load test cannot be regarded as signifying the presence of the entire HIV genome, and therefore the test cannot be used to detect the virus.
1.10. Results of the viral load test cannot be reproduced. This can be seen in the wide range of variability that is accepted in the quality controls set by the companies that make and commercialize the test kits. For example, Roche accepts a low control range having between 1,200 and 11,000 copies per ml [Lot # 0047], and a high control having a range between 99,000 and 750,000 copies per ml [Lot # A00246] [Roche, Amplicor HIV-1 Monitor test Lot # B00985, expiration August 2000]. Most importantly, the difficulties inherent in the lack of a gold standard for HIV infection also apply to the evaluation of the accuracy of the PCR or Viral load test (12,41,42). As a consequence, the specificity of the viral load test for HIV has never been defined properly. Therefore, all viral load positive results for HIV are false-positives.
1.11. The fact that those who propose HIV as the cause of AIDS were forced to appeal to what amounts to a genetic trick — the PCR test — is a strong argument against HIV as the cause of AIDS. To have to amplify infinitesimal amounts of genetic material in the blood of AIDS patients in order to identify HIV, instead of culturing the entire virus, isolating it, and purifying it, violates one of the central tenets of infectious disease: at the climax or maximum state of severity of any infectious disease is when the patient has the greatest number of microbes in his/her tissues. It is in those moments that it is easiest to isolate and purify the microbes that are actually causing a disease.
1.12. People have the right to make informed choices (43-45). However, the right to informed choice implies a right to solid information. There is no justification for the fact that most people have not been informed about the serious inaccuracy of the tests for HIV infection. Withholding or obscuring these facts is a serious breach of public trust, violating as it does a person's right to informed consent when making decisions about health care. The legal implications of this situation have been noted (46).
2. Being "HIV-positive" does not mean that a person is infected with "HIV"
2.1. There exists a growing number of scientific publications detailing the fact that the tests for HIV infection are not specific for HIV (12-14,47). There are numerous reasons other than a past or present HIV infection to explain why an individual might react positively on these tests. In other words, even in the absence of HIV, these tests can react positively (12-14,17-19,30).
2.2. Some of the conditions that cause false positives on the so-called "AIDS test" are: past or present infection with a variety of bacteria, parasites, viruses, and fungi, including tuberculosis, malaria, leishmaniasis, influenza, the common cold, leprosy, or a history of sexually transmitted diseases; the presence of polyspecific antibodies, hypergammaglobulinemias, the presence of auto-antibodies against a variety of cells and tissues, vaccinations, and the administration of gamma globulins or immunoglobulins; the presence of auto-immune diseases like erythematous systemic lupus, sclerodermia, dermatomyositis and rheumatoid arthritis; the existence of pregnancy and multiparity; a history of rectal insemination; addiction to recreational drugs; several kidney diseases, renal failure and hemodialysis; a history of organ transplantation; the presence of a variety of tumors and cancer chemotherapy; many liver diseases, including alcoholic liver disease; hemophilia, blood transfusions and the administration of coagulation factor; and even the simple condition of aging, to mention but a few (12-14,17,18,30).
2.3. It is interesting to note that all of these conditions that cause the "HIV tests" to react positively in the absence of HIV are conditions which are present with varied distribution and concentration in all of the conventionally recognized AIDS risk groups in the developed countries, as well as in the vast majority of inhabitants of the underdeveloped world. This means that in all probability many drug users (including mothers), certain gay males, and some hemophiliacs in the developed countries, as well as the vast majority of inhabitants in most countries of Africa, Asia, South America and the Caribbean, who have positive reactions to the tests for HIV, may very well do so due to conditions other than being infected with HIV (12-14,30,48).
2.4. Further, it is well known that people with or at risk for AIDS have high levels of antibodies — immunoglobulins — as a consequence of having been exposed to significant quantities of a variety of foreign substances, such as recreational drugs, semen, factor VIII, blood and blood components, sexually transmitted infections, and other infections (12-14,49). All these substances are oxidizing agents that cause oxidative stress (47,50,51).
2.5. Recently I had the opportunity to carry out an experiment in which I was able to demonstrate that all blood reacts positively on the ELISA test when the test is run with “neat”, or undiluted, serum. This could indicate that everybody has antibodies against what is supposed to be HIV. The individuals that react positively only with straight or neat serum would have a smaller amount of antibodies than the ones that continue reacting positively even when the serum is diluted 400 times (88). This possibility has been confirmed by Yugoslavian and Italian researchers (90).
2.6. There is also a great deal of scientific data indicating the widespread presence of non-specific interactions between what are considered to be retroviral antigens and unrelated antibodies (12,52-54). It is therefore possible to conclude that the tests for HIV react positively in the presence of those antibodies; in other words, that a positive result on an antibody test for HIV may be the result of previous antigenic over-stimulation, rather than a result of an HIV or any other retroviral infection (12-14).
2.7. Finally, it has been proposed that antibodies against HIV are surrogate markers for recreational drug use in the United States and in Europe (55,56).
2.8. On the other hand, even if "the AIDS test" were able to detect antibodies to HIV, it would be illogical to say that the presence of those antibodies indicate an active infection. The presence of antibodies to any virus simply means humoral immune response to that virus and not necessarily that the virus is still active and pathogenic (48,58). One can have antibodies against many germs without those germs being active, pathogenically active or even present at all (58,59). In most instances, antibodies against viruses indicate immunity. This is the very basis of vaccination against viral diseases (48,58,60). Even if the tests were specific for antibodies against HIV, the question would then be the following: Why is it that only in the case of AIDS does the presence of antibodies indicates the presence of disease, rather than protection against it?
2.9. There is no justification for the fact that both patients and the general public have had all of the preceding facts withheld from them. Without knowledge of the merits and demerits of the tests for HIV, people cannot make informed decisions.
3. The so-called "AIDS virus", HIV, may not even exist
Biophysicist Eleni Papadopulos-Eleopulos and her group of researchers at Royal Perth Hospital in Perth, Western Australia, were the very first scientists to document the fact that HIV has never been isolated (12). For several years Papadopulos-Eleopulos and coworkers have been publishing papers in which they have described in detail the scientific facts supporting the assertion that the so-called AIDS virus, HIV, may not even exist (12-14,20,30,31,47,50,61-64).
3.1. The correct procedures (31), employed for over half a century, to achieve isolation of a retrovirus are: a) Find in infected cell cultures particles, with a diameter of 100-120 nM, that contain the so-called condensed inner bodies or cores and that have surfaces studded with projections — spikes or knobs; b) In sucrose density gradients the particles band at a density of 1.16 gm/ml; c) At the density of 1.16 gm/ml there is nothing else but particles with the morphological characteristics of retroviral particles; d) The particles contain only RNA and not DNA, and the RNA consistently has the same length (number of bases) and composition no matter how many times the experiment is repeated; e) When the particles are introduced into secondary cultures they are taken up by the cells, the entire RNA is reverse transcribed into cDNA, the entire cDNA is inserted into the cellular DNA, and the DNA is transcribed back into RNA which is then translated into proteins; f) As a result of e the cells in the secondary cultures release particles into the culture medium; g) The particles released into the secondary culture medium have exactly the same characteristics as the original particles, that is, they must have identical morphology, band at 1.16 gm/ml and contain the same RNA and proteins (31).
None of these procedures have been achieved in the case of HIV (12,14,31,47).
3.2. None of the researchers who claim to have isolated HIV have shown the presence of particles with the morphological characteristics of retroviruses banding at 1.16 gm/ml (31).
Even the word "isolation," as used by the most noted researchers (65-67), is incorrect and misleading, since neither Montagnier, Gallo nor Levy isolated HIV particles, particles of any other human retrovirus, or any virus-like particles at all (12-14,30,31,47,61,68-74).
3.3. Since no "retroviral particles" (retroviruses) have ever been isolated from any culture (12-14,31,47,61-63,69-75), the existence of HIV has been established indirectly: by the presence, in the blood cultures from AIDS and "HIV-positive" individuals, of proteins/glycoproteins such as gp 160/150, gp120, gp41/45/40, p34/32, p24, and p18/17, each claimed to belong to HIV; by the presence of enzymes such as reverse transcriptase, supposedly unique to HIV; and by the presence of RNA or DNA fragments that supposedly belong to HIV (12-14,31,47,61-63,69-75).
However, none of these substances have been proven to belong to HIV (12-14,31,47,61-63,69-75). How can it be proven that the substances found in these cultures belong to a viral particle that has never been found at 1.16 gm/ml? To prove that those substances are part of a retrovirus named HIV, it is absolutely necessary that the retroviral particles have been previously separated — isolated — from everything else. This has never been done with HIV (31).
3.4. It is interesting to note that the substances listed in 3.3 are claimed to appear exclusively when one co-cultures supposedly infected blood with abnormal cells from leukemia patients, or with cells from umbilical cord lymphocytes (31). The difficulty is that identical substances can be obtained from these same cultures in the absence of the supposedly HIV-infected blood (31).
3.5. The cultures in which the above substances have been found are cultures that have been heavily stimulated with chemicals such as phytohemagglutinin, IL-2, antiserum to human interferon, and other agents (31). These culture stimulants are oxidizing agents (31,47). The difficulty is that identical types of material can be observed in the stimulated cultures of lymphocytes from healthy persons (31,76).
It is interesting to note than in the presence of antioxidants, no HIV phenomena is observed in culture, nor can HIV substances be found (12,64,76).
3.6. The substances listed in 3.3 are not specific to HIV (31). For instance, it is currently known that reverse transcriptase can be found associated with entities other than retroviruses, including eukaryote cells, some animal and plant DNA viruses, and even some introns (77).
Gallo and co-workers have claimed that the cell-free supernatants from "infected" cultures contain HIV-DNA (78,79). They forget that, by definition, retroviruses are infectious particles that contain only RNA. When retroviruses enter a cell the RNA is reverse transcribed into DNA, which is then integrated into cellular DNA as a provirus, which means that "HIV DNA" will be present only within the cell and nowhere else (31).
There is also ample evidence that any RNA or DNA present in the supernatant of the cultures is there as an effect of stimulation by polycations and oxidizing agents, rather than as an effect of the presence of a retrovirus (31).
"HIV cloning" is likewise misleading. Without isolating a retroviral particle containing RNA inside its core, the cloning of that "specific HIV-RNA" is not possible (31).
3.7. To date no one has presented evidence that the so-called HIV proteins or antigens (gp160/150, gp120, gp41/45/40, p34/32, p24, p18/17) are constituents of a retrovirus particle or even a retrovirus-like particle, let alone a unique retrovirus, HIV (31).
3.8. The proteins or antigens derived from stimulated cultures form the basis for the ELISA and Western blot HIV antibody tests (31,73). Fragments of RNA from stimulated cultures form the basis of the HIV viral load test (31,73). This is the primary reason why the current tests used for the diagnosis of HIV are, in fact, not specific for HIV (12-14,31,61,62).
3.9. In the January 1997 issue of the journal Virology, two independent groups of researchers published experiments claiming HIV isolation. Here, for the very first time in the history of HIV, researchers followed the internationally accepted procedures for the isolation of retroviral particles. Not surprisingly, in the sedimented bands at 1.16 gm/ml of sucrose, where retroviruses are known to be located, nothing was found but cellular debris. At 1.16 gm/ml there was nothing that even resembled a retroviral particle (80-81). They were unable to isolate HIV simply because HIV was not there to be isolated.
It has been proposed that all of the substances that are said to indicate the existence of HIV are nothing more than non-viral material, the production of which is induced by the chemical agents to which the AIDS patients and cultures are exposed (31). When found in patients, these substances could be seen as the regular products of the stress response (82), secondary to exposure to chemical, physical, biological, mental, and nutritional stressor agents (48,51,57,83-87).
3.10. It is therefore possible to conclude that the entire model of AIDS as an infectious and transmissible viral disease has as its basis a non-existent organism. The foundation stone for the HIV/AIDS model, then, is a ghost.
4. The real meaning of being HIV-positive
4.1. The above considerations allow one to propose that reactivity on the ELISA, Western blot, and PCR tests is caused by multiple, repeated, and chronic exposure to chemical, physical, biological, mental, and nutritional stressor agents. The degree of reactivity would be proportional to the level of exposures to immunological stressor or oxidizing agents (12-14,20,30,31,63,88,89).
Positive results on ELISA and Western blot tests, can also be understood as the consequence of the presence of high levels of polyspecific antibodies, due to a state of chronic polyantigenic stimulation (52-54). The reactivity on the three main tests for HIV — ELISA, Western blot, and PCR or viral load — would be simply the result of the stress response (82,88,89,91-94).
4.2. Being "HIV-positive" — reacting positively on the tests for HIV — would then mean simply that the person has been exposed to many antigenic and toxic challenges, i.e., to many oxidizing agents (47,50,89). His or her immune system has been over-responding to these immunogenic and immunotoxic challenges (51,57,89). The immune system of these "HIV-positive" individuals would be debilitated — oxidized — after it had been over-stimulated and intoxicated. Therefore, in such individuals, the risk for AIDS would be higher than in those who are "HIV-negative" (12,13,49,51).
4.3. Without doubt, there exists an almost perfect correlation between the reactivity on the so-called "tests for HIV" and AIDS.
Exposure to immunological stressors causes the tests to react positively. In like manner, exposure to immunological stressors or oxidizing agents is the cause of the mild to moderate levels of immune suppression present in all non-symptomatic individuals who react positively on the "tests for HIV." If exposure to immunological stressors is not relieved, and if the individual is not disintoxicated, it is highly probable that the non-symptomatic "HIV-positive" individual will experience greater immune suppression and will develop the clinical manifestations of AIDS.
What is known as HIV has no causative role in AIDS. On the contrary, the HIV phenomenon is itself one of the effects of the stress response to multiple, repeated, and chronic exposures to chemical, physical, biological, mental, and nutritional stressor agents.
5. Possible trial to find out the real meaning of the tests for HIV
Take blood from four groups of people and run the tests highly diluted, undiluted and at a wide spectrum of dilutions in between: a) The first group would be a group of healthy people from many age groups; b) the second group would be a group of people from the conventional AIDS risk groups; c) the third group would be a group of people with clinical conditions unrelated to AIDS; and d) the fourth group would be a group of patients with full manifestations of AIDS.
All groups would be subjected to both ELISA and Western blot tests. Additionally, all blood samples could be subjected to the viral load test for HIV.
The results of such an experiment could determine whether these test measurements bear any relationship to an individual's level of exposure to stressor or oxidizing agents. If so, the tests could be salvaged as a measure of an individual's level of intoxication.

1. NUTRITIONAL IMMUNOLOGY.
The effects of malnutrition on lymphoid organs were first described during the middle of the 19th century (1). Lymphoid tissues are particularly vulnerable to the damaging effects of malnutrition and lymphoid atrophy is a prominent feature in nutritional deprivation (2-5). Cell division is a very singular characteristic of the functioning of immunocompetent cells. All types of immune cells and their products, such as interleukins, interferons, and complement, are known to depend on metabolic pathways that employ various nutrients as critical co-factors for their actions and activities (5,6). Most of the host defense mechanisms are altered in protein caloric malnutrition (PCM), as well as during deficiencies of trace elements and vitamins (2,4,7,8).
Patients with PCM have impaired delayed cutaneous hypersensitivity, poor lymphocyte proliferation response to mitogens, lower synthesis of lymphocyte DNA, reduced numbers of rosetting T lymphocytes, impaired maturation of lymphocytes seen through an increased deoxynucleotidyl transferasa activity, decreased serum thymic factor, fewer CD4+ cells, decreased CD4+/CD8+ ratio, impaired production of interferon gamma and interleukin 2, altered complement activity (especially reduction of C3, C5, factor B and total hemolytic activity), poor secondary antibody response to certain antigens, reduced antibody affinity, impaired secretory immunoglobulin A response, decreased antibody affinity, and phagocyte dysfunction (2-7).
Human malnutrition is usually a composite syndrome of multiple nutrient deficiencies. However, isolated micronutrient deficiencies do happen. Vitamin A deficiency results in reduction in the weight of the thymus, decreased lymphocyte proliferation, impaired natural killer cell and macrophage activities, and increased bacterial adherence to epithelial cells (8-11). Vitamin B6 deficiency produces failure of several components of both cell-mediated and humoral immune responses (2,4,7). Vitamin C deficiency impairs phagocytosis and cell-mediated immune reactions (12). Vitamin E deficiency also alters immune responsiveness (2,4,7). Zinc deficiency generates lymphoid atrophy, reduces lymphocyte responses and skin delayed hypersensitivity (2,4,7). Copper and selenium deficiencies impair T and B lymphocyte functions (2,4,7). Dietary deficiencies of selected amino acids such as glutamine and arginine also alter immunity (2,4,7).
Intrauterine malnutrition causes prolonged, even permanent, depression of immunity in offspring (13-14).
Considerable data implicate excess lipid intake in the impairment of immune responses (15). The potential for free radical damage is dependent in large part on the level of potentially oxidizable fatty acids, mainly polyunsaturated fatty acids (PUFAs) in the diet (15). High levels of dietary PUFAs have been shown to be immunodepressive. Dietary fats may undergo free radical-mediated oxidation prior to ingestion, as can occur when foods are fried (15). Animals fed oxidized lipids show marked atrophy of the thymus and T lymphocyte dysfunctions (15).
At the molecular level, the damage to immunocompetent cells by several nutritional deficiencies (PCM, Vitamin A, Vitamin C, Vitamin E, zinc, copper, zelenium deficiencies) is caused by increased free radicals through oxidative stress (8-11,15,16).
2. NUTRITIONAL DEFICIENCIES AND HIV/AIDS.
Since the beginning of the AIDS epidemic, researchers have provided scientific evidence that supports the possibility that AIDS can be effectively prevented, treated, and overcome by guaranteeing an optimal nutritional status to the individual or the patient (17,18). However, it seems that propaganda spread by pharmaceutical companies to commercialize antiretroviral medications has prevented these ideas from being widely accepted, despite the toxicity of these medications.
Early in the AIDS era, well recognized researchers in the field of nutrition and immunology, such as Dr. Ranjit Kumar Chandra, noticed that: “There is an uncanny similarity between the immunological findings in nutritional deficiencies and those seen in acquired immunodeficiency syndrome, AIDS” (17).
“There is a similarity between the immune deficiency, multiple infections, and severe weigh loss seen in AIDS patients, and the association of protein caloric malnutrition (PCM) with reduced resistance to infection observed in malnourished children, particularly in the Third World.” “It is also possible that nutritional deficiency may play a significant role in the clinical course of the immunodeficient state.” “These similarities between AIDS and PCM suggest that nutrition may contribute to the immunodeficient state. The immunodeficiency in children with PCM can be reversed by nutritional rehabilitation, which suggests that restoration of nutritional state may be a useful adjunct to therapy for AIDS patients” (19).
As described above, the immunological alterations found in PCM are practically identical to those of AIDS: impaired delayed cutaneous hypersensitivity, lymphocyte proliferation response to mitogens, complement activity and secondary response to antigens. There is also a reduced number of rosetting T lymphocytes, increased deoxynucleotidyl transferase activity, decreased serum thymic factor, fewer helper T cells, impaired production of interferon gamma and interleukins 1 and 2, reduced antibody affinity, impaired secretory immunoglobulin A (IgA) antibody response and phagocyte dysfunction. The proportion of helper/inducer T lymphocytes recognized by the presence of CD4 positive antigen on the cell surface is markedly decreased. The ratio CD4/CD8 is significantly decreased. Lymphoid atrophy is a prominent feature of nutritional deprivation. Serum antibody responses are generally intact in PCM. Most complement components are decreased, especially C3, C5, factor B and total hemolytic activity (20-26).
“Nutritional problems have been a part of the clinical aspects of AIDS from its earliest recognition as a new disease” (20,24). “In fact, in many AIDS patients, death seams to be determined more by the individual's nutritional status than by any particular opportunistic infection. This is, when wasting of lean body mass approaches 55% of normal for age, sex, and height, death is imminent regardless of the forces resulting is such profound malnutrition” (20-24). Moreover, the severity of the clinical manifestations of AIDS is proportional to the degree of the nutritional deficiencies (27-30).
In addition to supporting optimal function of the immune system, nutrition is especially critical in children, as it provides the best opportunity for normal growth and development (31,32).
“All persons with HIV infection should be screened for nutritional problems and concerns at the time of their first contact with a health care professional, and routine monitoring should be performed on an ongoing basis” (31).
Scientific evidence strongly suggests that nutritional and antioxidant deficiencies are a prior requisite to both reacting positively on the tests for HIV (ELISA, Western blot, Viral Load) (33-36) and progressing to AIDS (37,38).
3 NUTRITIONAL DEFICIENCIES AND THE PROGRESSION OF HIV-POSITIVE INDIVIDUALS TO AIDS.
An optimal nutritional status as well as adequate vitamin levels are known to be, by themselves, enough to prevent the development of AIDS in people who react positively on the tests for HIV (39-46).
For example, regarding vitamins in HIV disease progression and vertical transmission, researchers from the Harvard School of Public Health state: “The higher rates of HIV progression and vertical transmission in developing countries coincide with similarly higher rates of malnutrition and vitamin deficiencies, indicating that HIV infection, may be modified by nutritional status.” “Numerous observational studies report inverse association between vitamin status, measured bio-chemically or as levels of dietary intake, and the risk of disease progression or vertical transmission.” “Adequate vitamin status may also reduce vertical transmission through the intra-partum and breastfeeding routes by reducing HIV viral load in lower genital secretions and breast milk” and “vitamin supplements may be one of the few potential treatments that are inexpensive enough to be made available to HIV-infected persons in developing countries” (47).
Growing numbers of scientific trials implicate low serum vitamin A levels as a risk factor for HIV-positive individuals to progress to the clinical manifestations of AIDS (48-60).
“The risk of death among HIV-infected subjects with adequate serum vitamin A levels was 78% less, when compared with Vitamin A-deficient subjects” (47,52).
“In a study carried out among HIV-positive homosexual men, development of Vitamin A deficiency over an 18-month period was associated with a decline in CD4 cell count, widely used as a marker of HIV immune impairment. Normalization of vitamin A was associated with higher CD4 cell counts” (37, 47).
“Lower serum levels of vitamin A were associated with a faster rate of progression among men who participated in the Multicenter AIDS Cohort Study (MACS)” (42, 47).
On the other hand, “among well nourished HIV seropositive men who participated in the San Francisco Men's Health Study, high energy-adjusted vitamin A intake at baseline was associated with higher CD4 cell counts at baseline, as well as with lower risk of developing AIDS during the 6 year period follow up” (44, 47).
“In a placebo-controlled trial in South Africa among children born to HIV-positive women, Vitamin A supplements resulted in approximately 50% reduction in diarrheal morbidity among HIV-infected children” (47,51).
Besides vitamin A, a growing number of studies show that “HIV-positive” individuals are at higher risk of deficiency of vitamins B1, B2, B6, B12, C, D, and E (47,61-68). Furthermore, deficiencies of B-complex vitamins, vitamin C, vitamin E and vitamin D increment the risk of progression of “HIV-positive” individuals to AIDS (47,61-68).
4. NUTRITIONAL DEFICIENCIES AND THE “TRANSMISSION” OF HIV/AIDS.
Several studies show that vitamin A deficiency is more prevalent among HIV-positive persons compared with HIV-negative individuals (28,38,40,50,57).
Low levels of vitamin A and carotenoid were found to be a risk factor for reacting positively on HIV tests in Pune, India (69), for seroconversion among Kenyan men with genital ulcers (70), and for seroconversion among Rwandan women (71).
There are several trials investigating the role of vitamin A and carotenoid deficiencies in mother to child transmission of HIV/AIDS (MTCT) during pregnancy, delivery, and breastfeeding (72-89).
In Tanzania, for example: “Multivitamin supplementation is a low-cost way of substantially decreasing adverse pregnancy outcomes and increasing T-cell counts in HIV-1 infected women” (72,73).
“A growing body of data suggests that low serum levels of vitamin A among HIV-infected pregnant women is associated with higher risk of vertical transmission of HIV” (47).
“Mean vitamin A concentration in 74 mothers who transmitted HIV to their infants was lower than that in 264 mothers who did not transmit HIV to their infants” (77).
“In Malawi, higher serum retinol of HIV-infected pregnant women was associated with a reduced risk of vertical transmission” (47,77).
“Women who had increasing serum retinol levels over time, however, were at a lower risk, whereas women who had declining serum retinol were at a higher risk of transmitting the virus” (47,89).
“Vitamin A supplementation to a population of HIV-infected pregnant women, many of whom had low vitamin A levels, was associated with a decreased number of preterm births and with reduced mother-to-child transmission of HIV in preterm babies, but was not associated with a reduction in HIV transmission overall. Vitamin A decreased HIV transmission in the preterm babies by 47%” (80).
“Detection of vaginal HIV-1 DNA was associated with abnormal vaginal discharge, lower absolute CD4 cell count, and severe vitamin A deficiency” (85).
“Women with CD4 cell depletion, especially those with vitamin A deficiency, may be at increased risk of transmitting HIV-1 to their infants through breast milk” (88).
“Increased risk of maternal-infant transmission was associated with severe vitamin A deficiency among non-breastfeeding women” in the United States (76).
Scientific studies, therefore, support the contention that the use of vitamins by themselves, especially vitamin A, could be enough to avoid what is known as transmission of HIV (47,69-89). If this is the case, as many clinical trials and scientific papers contend, supplementation with vitamin A and carotenoids would constitute an effective, inexpensive and non-toxic practice for African countries.
5. OXIDATIVE STRESS AND HIV/AIDS.
Moreover, since the beginning of the AIDS epidemic, free radicals and, specifically, oxidizing agents, have been implicated in the pathogenesis of this new syndrome (90,91). There have been international meetings on the role of oxygen free radicals in HIV/AIDS (92,93).
There are currently increasing numbers of scientific publications demonstrating that oxidizing stress is an absolute requisite for both testing positive on the tests for HIV (94-100) and developing the clinical manifestations of AIDS (101-123).
Free radical reactions of special significance to immunological phenomena include, for example, the many oxidizing agents that can abstract a hydrogen atom from thiol groups to form thiol radicals (124-126). Thiol groups are important for enzyme activities, receptor functions, disulphite links in immunoglobulins, and T cell activation and proliferation. The super oxide anion radical can react with nitric oxide, resulting in a loss of endothelium-derived relaxing factor activity, which is important in the inflammation/disinflammation process. Methionine oxidation can cause protein damage with subsequent changes in immunogenicity. Proteolysis can be increased by free radical damage. The per oxidation of lipids by reactive free radicals produces many biological modulators, such as, for example, the 4-hydroxy-alkelans, which produces strong chemotactic activity for phagocytes, alters the adenyl cyclasa system, increases capillary permeability, and alters lymphocyte activation. Lipid hydroperoxides, also from per oxidation of lipids, alter lymphocyte activation. Conditions favoring lipid per oxidation may result in chemo taxis of leukocytes, protein modification, immune complex injury, and cell death (124-126).
Free radicals are produced throughout the regular immune system network. Despite the beneficial effects of the inflammation responses, it can also aggravate existing tissue damage by releasing free radicals. When uncontrolled, initiated by an abnormal stimulus, or occurring for prolonged periods of time, inflammation may become a disease process (124-126). It is critical for optimal immune responses that there be a balance between free radical generation and antioxidant protection. During phagocytosis by polymorphonuclear leukocytes, for example, super oxide anion radicals are released. These oxygen free radicals can oxidize thiol groups to thiol radicals and can stimulate lipid per oxidation with the formation of H2O2, which is highly significant in the mechanisms of cell injury. Oxygen free radicals produced during phagocytosis of immune complexes are associated with injury due to immune complexes (124-126).
It has been proposed many times that free radicals and, specifically, oxidizing species, play important roles in the pathogenesis of AIDS (91-93,127-129).
The above are the scientific fundamentals for the use of antioxidants such as vitamin A and carotenoids, vitamin C, vitamin E, selenium, n-acetyl cisteine, l-gluthamin, zinc, cooper, manganese, alphalipoic acid, coenzyme Q10, and flavonoids or vitamin P, as supplementation for the prevention and treatment of AIDS (90-129).
6. NUTRITIONAL AND ANTIOXIDANT DEFICIENCIES AND THE PATHOGENESIS OF HIV/AIDS.
African countries have a high incidence of malnutrition, vitamin deficiencies, anemia, bacterial, viral, fungal, and parasitic infections and infestations.
For any infectious or parasitic disease to begin, it is always requisite that the host suffers immunodeficiency (130). At the same time, infectious and parasitic diseases cause, by themselves, more immune suppression and more malnutrition (131,132). This immunesuppression is secondary to the accumulation of free radicals, especially oxidizing species, that occur during and after infectious and parasitic diseases (125,133).
Therefore, in African countries, a persistent cycle occurs: poverty, malnutrition, immunesuppression, infectious and parasitic diseases, more immunesuppression, and more malnutrition (134,135).
On the other hand, there is growing scientific data showing that many chronic diseases of adulthood have their origin at “in utero programming” (136-139). This includes illnesses such as coronary heart disease and stroke, hypertension, type II diabetes and other endocrine alterations (136-141), as well as several immunological disturbances (142-152). Therefore, it appears that whatever happens during embryonic and fetal times is remembered by cells, tissues, organs, and systems throughout the lifetime.
“Research in Gambia associated season of birth with infectious disease mortality after the age of 15 years, suggesting an association between prenatal undernutrition, immune function, and adult vulnerability to infectious disease” (148,152). Prenatal undernutrition has been found to impair antibody responses to vaccination with Salmonella thyfi that last at least up to adolescent times (146). The findings of these researchers “suggest a role for fetal and early infant experience in programming the immune system” which may accompany the individual during its entire life (145,146).
It has been scientifically demonstrated that prenatal undernutrition alters several aspects of cell-mediated immunity, causes involution of lymphoid tissues such as the thymus, and suppression of antibody responses to vaccination. These deficits persist for weeks or, in some cases, even years (142-152).
In addition, “murine models have documented impairments in immunity after maternal undernutrition that last through adulthood and into the next generation, despite ad libitum feeding of both F1 and F2 generations” (153). Also in mice, deprivation of zinc during pregnancy causes immunodeficiency that can last at least for three generations (154).
It is therefore very probable that in Africa the consequences of poverty and malnutrition are being transmitted from generation to generation with a cumulative effect and that AIDS in Africa may be the topmost consequence of these cumulative effects of poverty.
In this light, the crucial role of maternal undernutrition in the pathogenesis of pediatric AIDS must seriously be considered a reality in developing countries (155,156). This reasoning indicates that malnutrition constitutes the main risk factor for AIDS in adults in developing countries (155,156). Scientifically speaking, there is no rationale for indicting sexual promiscuity as the cause of AIDS in Africa, while underestimating the role of poverty, malnutrition, infections and parasites.
7. NUTRITIONAL AND ANTIOXIDANT THERAPY FOR THE PREVENTION AND TREATMENT OF AIDS.
“It is not surprising, therefore, that dietary therapy for AIDS has been proposed, debated, and, more importantly, surreptitiously or overtly used from the early days of the epidemic” (24).
Twenty years later, researchers insist: “Because nutrient deficiencies may play an important role in the pathogenesis of HIV disease, medical nutrition therapy and counseling are critical aspects of treatment” (31). Nutritional (157-179) and antioxidant (180-198) therapy is therefore requisite in preventing and treating AIDS.
Clinical trials have identified in detail the vitamin and mineral needs of HIV-positive persons and those with AIDS. These studies suggest the need for increasing the intake of the following micronutrients as supplementation for the prevention and treatment of AIDS: vitamin A and carotenoids, vitamin C, vitamin E, selenium, n-acetyl cisteine, l-gluthamin, zinc, cooper, manganese, alphalipoic acid, coenzyme Q10, flavonoids or vitamin P, and B-complex vitamins (17-38,90-129,157-198).
When providing Vitamin A as a supplement its potential teratogenic property should be kept in mind (199). In this regard, the World Health Organization recommends that pregnant women should not take more than 10,000 IU of Vitamin A per day (47).
If we really want to prevent and treat AIDS in Africa, it is absolutely requisite to provide at least the minimum food needs to HIV-positive individuals, to AIDS patients, as well as to all African communities.
A diet that provides adequate sources of vitamins, minerals, and antioxidants might have quantities of fruits, especially papaya, mango, kiwi, pineapple, avocado, bananas, and dry fruits, and vegetables, legumes, and alga. Use few animal products. Prefer fatty white fish, sheep and goat meat. Prefer sea salt. Use 60-80% fresh, whole, raw organic food. Use garlic, onions, asparagus, beets, cabbage, broccoli, cauliflower, Brussels sprouts, carrots, yeast, whet, pollen, as well as sprouts, legumes, and cereals. Prefer cool press oils (below 40 degrees Celcius) since this process preserves essential and polyunsaturated fatty acids needed in anti-inflammatory and regenerative processes. Carcamo, sunflower, and olive oils, in this order, are good sources of vitamin F or linoleic acid. Lino oil is a good source of alpha linoleic acid. Eat whole cereals in any preparation (rice, barley, wheat, oat). Decrease sugar and candies. Prefer raw organic vegetables and legumes. Drink lots of liquids: water (at least 1.5 litters per day), juices from fresh fruits and vegetables, especially carrots, vegetable broths, and green juices as a source of chlorophyll (for example, blend water, lettuce, spinach, celery, mint, parsley, coriander, and similar ingredients, and take without draining). It is also very convenient to use bifidogenic foods, for example yogurt and kumis better, if made with sheep or goat's milk, tofu, or miso. Coconut oil is a good source of louric and caprilic acids which are anti-candida (164,169,173-179,200).
Immune stimulating and/or antioxidant herbs include: Aloe (Aloe vera), astragalus (Astragalus membranaceus), Siberian ginseng (Eleutherococcus senticosus), Fo-ti (Polygonum multiforum), turmeric (Curuma longa), echinacea (Echinacea angustifolia y E. purpurea), garlic (Allium sativum), licorice or liquorice (Glycyrrhiza glabra), golden seal (Hydrastis Canadensis), cat's claw (Uncaria tomentosa), ginkgo (Ginkgo biloba), grape fruit seeds (Vitis vinifera), zarzaparrilla or smilax (Smilax officinalis y S. aspera), Southerlandia (African herb); sedative and relaxing herbs include peace flower (Passiflora incarnata), valerian (Valeriana officinalis), chamomile (Matricaria chamomilla), mint (Menta sativa), lavender (Lavanda officinalis), and Siberian ginseng (Eleuterococus senticosus) (182,186,187,200-203).
A large number of scientific papers and books have been published reviewing the issue of nutritional and antioxidant therapy for the prevention and treatment of AIDS (157-206).
8. CONCLUSIONS
Nutritional and antioxidant deficiencies have been documented in all patients with AIDS.
Nutritional and antioxidant deficiencies are a requisite prior to reacting positively on “HIV tests.”
Nutritional and antioxidant deficiencies are also a requisite of “HIV-positive” individuals prior to the development of the clinical manifestations of AIDS.
Nutritional and antioxidant deficiencies play a major role in the pathogenesis of AIDS.
Nutritional and antioxidant supplements are being used successfully in preventing and treating AIDS. An optimal nutritional and antioxidant status can guarantee success in preventing and treating AIDS.
Some of the nutritional and antioxidant supplements that have been used in the treatment and prevention of AIDS are: vitamin A and carotenoids, vitamin C, vitamin E, selenium, n-acetyl cisteine, l-gluthamin, zinc, cooper, manganese, alphalipoic acid, coenzyme Q10, B-complex vitamins, and flavonoids or vitamin P.
To prevent and treat AIDS in Africa, an absolute requisite is the provision of at least the minimum food needs to HIV-positive individuals, to AIDS patients, and to all African communities. Moreover, diets rich in fresh and organic fruits, vegetables, and cereals, as well as diets rich in bifidogenic foods (yogurt, kumis) are known to be immune stimulants.
