Judge attacks South African government's response to AIDS

During the 13th international AIDS conference in Durban, Judge Edwin Cameron of the High Court in Johannesburg, castigated the South African government for its flirtation with those who claim that AIDS is not caused by HIV, and for its slow response to the epidemic. In his deliberation of the Jonathan Mann memorial lecture, the government was admonished for failing to adopt a program to prevent vertical transmission of HIV infection by providing pregnant women with antiretroviral therapy. Quoting an article by the African intellectual Dr. Mamphela Ramphele, he commented that failure to recognize HIV as the country's utmost priority is an irresponsibility that borders on criminality on the part of the government. Moreover, Cameron called on the pharmaceutical industry and developed countries to take steps to lower the prices of drugs and make them more readily available to poverty stricken countries that are more affected by the epidemic.     

Drug companies cut HIV drug prices in the developing world

The UN has reported that five multinational pharmaceutical companies would cut down HIV drug prices in the developing world. One of these drug companies is GlaxoWellcome, which has promised to reduce the price of zidovudine and lamivudine to US$2 in the poorest nations, a fifth of its price in the US. Although Peter Piot, director of the UN Program on HIV/AIDS, welcomed the companies' promises, he warned that price cuts alone will not curb the epidemic. He stated that this initiative is only one critical factor in what must become a much broader and more urgent effort to help people living with HIV/AIDS. Moreover, health and development agencies expressed concern that AIDS drugs will still be unaffordable for the vast majority of those in need in developing countries. In addition, poor countries lack the infrastructure to deliver these drugs safely and effectively. During the time of the UN announcement, US President Bill Clinton also signed an executive order allowing sub-Saharan Africa to adopt legal measures to obtain cheap HIV drugs. Meanwhile, South Africa's reaction to the offer to cut antiretroviral drug prices has been lukewarm.     

Mbeki appoints team to look at cause of AIDS

South African president, Thabo Mbeki, hosted a meeting of more than 30 scientists for a 2-day discussion on HIV and AIDS, particularly on the etiology of AIDS. At least half of the members of the Presidential Advisory Panel on AIDS disputed the orthodox views on AIDS, and many of them do not believe HIV causes AIDS. At the end of the 2-day session, a four-person team was appointed (two ?orthodox? scientists and two dissenting ones). This team and panel will work in a closed Internet session and will review scientific data and construct experiments to deal with questions that may yet be unanswered. The meeting took place against the background of a letter written by President Mbeki to President Clinton, Prime Minister Tony Blair, and several other world leaders, expressing his views on HIV and AIDS. Both in the letter and at the meeting, President Mbeki construed the reaction to his views as similar to the tyranny experienced by the oppressed in South Africa during the apartheid era.     

Constitutional values and HIV/AIDS in the workplace: reflections on Hoffman v. South African Airways

South Africa is experiencing an HIV/AIDS epidemic of enormous proportions. The workplace, like all the other sectors, is adversely affected. The tendency of a significant proportion of employers has been to discriminate against employees and job applicants living with HIV/AIDS through use of HIV testing to exclude those that are HIV-positive. In the case of Hoffmann v South African Airways, the Constitutional Court was asked to determine the constitutionality of excluding a job applicant on account of an HIV-positive status. The Court ruled in favour of the applicant and ordered instatement. Through an analysis of Hoffmann v South African Airways, the article examines how constitutional values are impacting on HIV/AIDS-related ethics in the workplace.     

South African public sceptical about new AIDS "cure"

Against a background of scams to treat HIV/AIDS, the government's erratic approach to the epidemic, and an increasingly cynical but desperate public, a team from the Medical University of South Africa recently announced Inactivan as an anabolic steroid which stops HIV from replicating in white blood cells. The development of the drug was announced in a well-publicized press conference after a 5-day trial on humans. However, few people in South Africa are ready to accept the team's findings since it comes shortly after 2 poorly-qualified scientists claimed to have found a cure for AIDS in 1998. Their drug, Virodene, was actually a toxic industrial solvent. South Africa's minister of health, Dr. Nkosazana Dlamini-Zuma, tarnished her reputation by associating herself with the drug, which had not been through any of the usual research protocols, peer review, or drug regulatory mechanisms.     

HIV/AIDS programmes should focus on improved access

This paper discusses the need for HIV/AIDS programs in sub-Saharan countries to focus more on improved access to information to empower poor people living in remote areas. It is noted that despite Glaxo Wellcome's move to reduce the cost of antiretroviral therapy, it is unlikely to have an impact on most of those infected with or affected by HIV/AIDS, since concerns regarding lack of sustainability, bureaucratic administration, and communication difficulties predominate in the country. In this regard, it is therefore recommended that national HIV/AIDS programs be balanced with the needs of both the community and the individual and in prevention and care. Health workers should be explicit in confronting traditional beliefs, such as those about gender roles and traditional medicine, in prevention campaigns. Moreover, there is also an urgent need to improve access to condoms; strengthen health programs such as directly observed treatment short-term (DOTS) courses for tuberculosis and the syndromic approach to sexually transmitted disease treatment; and improve practical support to communities caring for those who are sick and the orphans. Lastly, all partners working with prevention programs should use the more positive community attitudes towards HIV/AIDS issues seen in many sub-Saharan countries to develop evidence-based programs that focus more on improved access and less on sustainability.     

Understanding the Impact of Hazardous and Harmful Use of Alcohol and/or Other Drugs on ARV Adherence and Disease Progression

The objective of this study was to understand the impact of hazardous and harmful use of alcohol and/or other drugs on ARV adherence and disease progression among HIV patients. A cross-sectional study design was used. A total of 1503 patients attending HIV clinics in Cape Town, South Africa were screened for problematic substance use. A sub-sample of 607 patients (303 patients who screened positive for problematic substance use and 304 who did not) participated in this study. Hazardous or harmful alcohol use and problematic drug use predicted missing and stopping ARVs which, in turn, was associated with a decrease in CD4 counts and more rapid HIV-disease progression and poorer health outcomes in people living with HIV/AIDS (PLWHA). The findings of this study underscore the need for an integrated approach to managing substance-use disorders in PLWHA.     

Straight talk with...Seth Berkley by Khamsi Roxanne

On 13 June, donors to the GAVI Alliance will gather in London to affirm their commitment to fund immunizations in the developing world. At the meeting, participants will address the estimated $3.7 billion financing gap needed over the next four years to scale up childhood vaccination efforts to meet the demand forecasts for those countries that receive assistance from the Geneva-based organization. But attendees of the pledging conference will also be discussing something not on the formal agenda: the announcement last month that Seth Berkley, who founded and heads the International AIDS Vaccine Initiative (IAVI), will take over the helm of the alliance in August. Berkley will lead a unique chapter in GAVI's development as the organization narrows in on the looming deadline set by Millennium Development Goal 4, which aims to reduce child mortality by two thirds by 2015. Yet, in a sense, these efforts will be a continuation of the work Berkley has fostered at IAVI since he formally launched the New York-based nonprofit in 1996. Berkley, an epidemiologist who previously held jobs with the Rockefeller Foundation, the Carter Center and the US Centers for Disease Control and Prevention, has witnessed ups and downs in the vaccination field, from the disappointing STEP trial in 2007 to the more recent good news from the 2009 Thai study, which reported as much as 31% protection against HIV. Roxanne Khamsi spoke with Berkley about what he has learned in his quest for a preventative shot against AIDS.     

Forced Sexual Experiences as Risk Factor for Self-Reported HIV Infection among Southern African Lesbian and Bisexual Women

Even though women who have sex with women are usually understood to be at no or very low risk for HIV infection, we explored whether lesbian and bisexual women in a geographical area with high HIV prevalence (Southern Africa) get tested for HIV and whether, among those women who get tested, there are women who live with HIV/AIDS. The study was conducted in collaboration with community-based organizations in Botswana, Namibia, South Africa and Zimbabwe. Data were collected via written surveys of women who in the preceding year had had sex with a woman (18 years and older; N = 591). Most participating women identified as lesbian and black. Almost half of the women (47.2%) reported ever having had consensual heterosexual sex. Engagement in transactional sex (lifetime) was reported by 18.6% of all women. Forced sex by men or women was reported by 31.1% of all women. A large proportion of the women reported to ever have been tested for HIV (78.3%); number of lifetime female and male partners was independently associated with having been tested; women who had engaged in transactional sex with women only or with women and men were less likely to have been tested. Self-reported HIV prevalence among tested women who knew their serostatus was 9.6%. Besides age, the sole independent predictor of a positive serostatus was having experienced forced sex by men, by women, or by both men and women. Study findings indicate that despite the image of invulnerability, HIV/AIDS is a reality for lesbian and bisexual women in Southern Africa. Surprisingly, it is not sex with men per se, but rather forced sex that is the important risk factor for self-reported HIV infection among the participating women. HIV/AIDS policy should also address the needs of lesbian, bisexual and other women who have sex with women.     

Incidence of AIDS and excess of mortality associated with HIV in haemophiliacs in the United Kingdom: report on behalf of the directors of haemophilia centres in the United Kingdom.

OBJECTIVE--To estimate the cumulative incidence of AIDS by time since seroconversion in haemophiliacs positive for HIV and to examine the evidence for excess mortality associated with HIV in those who had not yet been diagnosed as having AIDS. DESIGN--Analysis of data from ongoing national surveys. SETTING--Haemophilia centres in the United Kingdom. PATIENTS--A total of 1201 men with haemophilia who had lived in the United Kingdom during 1980-7 and were positive for HIV. INTERVENTION--None. END POINTS--Diagnosis of AIDS; death in those not diagnosed as having AIDS. MEASUREMENTS AND MAIN RESULTS--Estimation of cumulative incidence of AIDS and number of excess deaths in seropositive patients not diagnosed with AIDS. Median follow up after seroconversion was 5 years 2 months. Eight five patients developed AIDS. Cumulative incidence of AIDS five years after seroconversion was 4% among patients aged less than 25 at first test positive for HIV, 6% among those aged 25-44, and 19% among those aged greater than or equal to 45. There was little evidence that type or severity of haemophilia or type of factor VIII or IX that had caused HIV infection affected the rate of progression to AIDS. Mortality was increased among those who had not been diagnosed as having AIDS, especially among those with "AIDS related complex." Thirteen deaths were observed among 36 patients diagnosed as having AIDS related complex against 0.65 expected, and 34 deaths in 1080 other patients against 22.77 expected; both calculations were based on mortality rates observed in haemophiliacs in the United Kingdom in the late 1970s. CONCLUSIONS--Rate of progression to AIDS depended strongly on age. There is a substantial burden of fatal disease among patients positive for HIV who have not been formally diagnosed as having AIDS.     

Oral candidiasis and oral yeast carriage among institutionalised South African paediatric HIV/AIDS patients

South Africa currently has an estimated 500,000 AIDS orphans, many of whom are HIV-positive. Oral candidiasis commonly occurs in both adult and paediatric HIV/AIDS patients. Published information on HIV-positive children in Africa mainly concerns hospitalised patients. The objective of this study was to determine the prevalence of oral candidiasis and oral yeast carriage among paediatric HIV/AIDS patients residing in orphanages in Gauteng, South Africa, and to compare the prevalence of isolated yeast species with species obtained from adult HIV/AIDS patients. Eighty-seven paediatric HIV/AIDS patients residing in five homes were examined and a swab taken from the dorsal surface of the tongue, cultured on CHROMagar and yeast isolates identified with the ATB 32C commercial system. The species prevalence of 57 identified isolates was compared with that of 330 isolates from adult HIV/AIDS patients. Twelve (13.8%) children presented with clinically detectable candidiasis. Yeasts were isolated from 0% to 53% of children in the individual homes, with Candida albicans (40.4%) and C. dubliniensis (26.3%) constituting the most frequently isolated species. Gentian violet prophylaxis was administered in one particular home and a higher carriage rate (66.6%) of non-C. albicans and non-C. dubliniensis was observed among these children. The prevalence of C. albicans was lower while the prevalence of C. dubliniensis, C. glabrata and C. tropicalis was significantly higher (p ≤ 0.001) among the children than among adult HIV/AIDS patients. These findings indicate a role for yeast culture and species determination in cases with candidiasis in institutionalized paediatric HIV/AIDS patients.     

HIV prevention in high-risk women in South Africa: condom use and the need for change

Introduction

Young women are at disproportionate risk of HIV infection in South Africa. Understanding risk behaviors and factors associated with ability to negotiate safe sex and condom use is likely to be key in curbing the spread of HIV. Traditionally prevention efforts have focused on creating behavioral changes by increasing knowledge about HIV/AIDS.

Methods

This was a cross-sectional analysis from a prospective observational cohort study of 245 women at a high-risk of HIV infection in KwaZulu-Natal, South Africa.

Results

Participants demonstrated a high level of HIV/AIDS knowledge. Overall, 60.3% of participants reported condom use. Reported condom use at last sexual encounter varied slightly by partner type (57.0% with steady versus 64.4% with casual partners), and self-perceived ability to choose to use a condom was significantly lower with steady partners compared to casual partners (p<0.01). In multivariate analysis, women who had high school education were more likely to use condoms at their last sex encounter compared to those with only primary school education (RR of 1.36 (95% Confidence Interval (CI) 1.06–1.75) and 1.46 (95% CI 1.13–1.88) for grades 8–10 and 11–12, respectively). Those who used condoms as a contraceptive method were twice as likely to use condoms compared to women who did not report using them as a contraceptive method. Greater perceived ability to choose to use condoms was associated with higher self-reported condom use at last encounter, irrespective of partner type (RR = 2.65 (95% CI 2.15–32.5).

Discussion

Self-perceived ability to use condoms, level of formal education and condom use as a contraceptive were all significantly associated with self-reported condom use at last sexual encounter. These findings suggest that that gender inequality and access to formal education, as opposed to lack of HIV/AIDS knowledge, prevent safer sexual practices in South Africa.     

AIDS awareness among rural Utah physicians.

Studies of physicians'' attitudes and knowledge of the acquired immunodeficiency syndrome (AIDS) and the clinical precautions they take against exposure to the human immunodeficiency virus (HIV) have focused on urban physicians. To determine rural physicians'' knowledge and attitudes about AIDS, a questionnaire was mailed to 321 physicians practicing in rural Utah. Of the 169 physicians who completed questionnaires, 96% thought that their community or area of service had only a minor or no problem with AIDS; 89%, however, thought that their chance of seeing a patient who was HIV-positive was fair to moderate. Of the 169 respondents, 3% were not sure whether they would even treat a patient who had AIDS, 67% said they would, and 30% said they would not. Although all physicians are at risk of seeing a patient who has had exposure to HIV and other blood-borne diseases such as hepatitis B, only 55% of the respondents felt a need to take clinical precautions to prevent their exposure to the virus. Our study shows the need for all rural Utah physicians to reevaluate their risk of exposure to HIV, to increase precautionary measures for their own protection, to consider the ethical responsibility of treating AIDS patients, and to take a more active role in teaching their patients how to protect themselves from exposure to the virus.     

Virginity Testing: Managing Sexuality in a Maturing HIV/AIDS Epidemic

KwaZulu-Natal province in South Africa is currently the site of the world's fastest growing HIV/AIDS epidemic, where it is estimated that between 30 and 40 percent of the adult population is seropositive for HIV. With support from local politicians and members of various government ministries, several self-styled guardians of tradition have emerged to form organizations that advocate and conduct regular virginity testing of girls. Reference to the current HIV/AIDS epidemic is central to calls for greater support of this practice. Drawing on original research among Zulu-speaking people in the periurban communities of Durban, this article examines the sociocultural construction of HIV/AIDS and locates the growing popularity of virginity testing within a gendered meaning-making process consistent with commonly held beliefs that the epidemic is the result of women being sexually "out of control." With the social impact of AIDS starting to take its toll in the forms of increasing AIDS-related deaths and a growing population of orphans, I argue that virginity testing is an attempt to manage the epidemic by exerting greater control over women and their sexuality. In addition, virginity testing of girls helps to draw attention away from the role of men in the maturing epidemic, consideration of which has been conspicuously absent in the popular discourse on AIDS at all levels of South African society.     

Exploring disparities between global HIV/AIDS funding and recent tsunami relief efforts: an ethical analysis

Objective: To contrast relief efforts for the 26 December 2004 tsunami with current global HIV/AIDS relief efforts and analyse possible reasons for the disparity. Methods: Literature review and ethical analysis. Results: Just over 273,000 people died in the tsunami, resulting in relief efforts of more than US$10 bn, which is sufficient to achieve the United Nation’s long‐term recovery plan for South East Asia. In contrast, 14 times more people died from HIV/AIDS in 2004, with UNAIDS predicting a US$8 bn funding gap for HIV/AIDS in developing nations between now and 2007. This disparity raises two important ethical questions. First, what is it that motivates a more empathic response to the victims of the tsunami than to those affected by HIV/AIDS? Second, is there a morally relevant difference between the two tragedies that justifies the difference in the international response? The principle of justice requires that two cases similarly situated be treated similarly. For the difference in the international response to the tsunami and HIV/AIDS to be justified, the tragedies have to be shown to be dissimilar in some relevant respect. Are the tragedies of the tsunami disaster and the HIV/AIDS pandemic sufficiently different, in relevant respects, to justify the difference in scope of the response by the international community? Conclusion: We detected no morally relevant distinction between the tsunami and the HIV/AIDS pandemic that justifies the disparity. Therefore, we must conclude that the international response to HIV/AIDS violates the fundamental principles of justice and fairness.     

Increase in non-AIDS related conditions as causes of death among HIV-infected individuals in the HAART era in Brazil

Background

In 1996, Brazil became the first developing country to provide free and universal access to HAART. Although a decrease in overall mortality has been documented, there are no published data on the impact of HAART on causes of death among HIV-infected individuals in Brazil. We assessed temporal trends of mortality due to cardiovascular diseases (CVD), diabetes mellitus (DM) and other conditions generally not associated with HIV-infection among persons with and without HIV infection in Brazil between 1999 and 2004.

Methodology/Principal Findings

Odds ratios were used to compare causes of death in individuals who had HIV/AIDS listed on any field of the death certificate with those who did not. Logistic regression models were fitted with generalized estimating equations to account for spatial correlation; co-variables were added to the models to control for potential confounding. Of 5,856,056 deaths reported in Brazil between 1999 and 2004 67,249 (1.15%) had HIV/AIDS listed on the death certificate and non-HIV-related conditions were listed on 16.3% in 1999, increasing to 24.1% by 2004 (p<0.001). The adjusted average yearly increases were 8% and 0.8% for CVD (p<0.001), and 12% and 2.8% for DM (p<0.001), for those who had and did not have HIV/AIDS listed on the death certificate, respectively. Similar results were found for these conditions as underlying causes of death.

Conclusions/Significance

In Brazil between 1999 and 2004 conditions usually considered not to be related to HIV-infection appeared to become more likely causes of death over time than reported causes of death among individuals who had HIV/AIDS listed on the death certificate than in those who did not. This observation has important programmatic implications for developing countries that are scaling-up access to antiretroviral therapy.     

Factors associated with HIV/AIDS diagnostic disclosure to HIV infected children receiving HAART: a multi-center study in Addis Ababa, Ethiopia

Background

Diagnostic disclosure of HIV/AIDS to a child is becoming an increasingly common issue in clinical practice. Nevertheless, some parents and health care professionals are reluctant to inform children about their HIV infection status. The objective of this study was to identify the proportion of children who have knowledge of their serostatus and factors associated with disclosure in HIV-infected children receiving HAART in Addis Ababa, Ethiopia.

Methods

A cross-sectional study was conducted in five hospitals in Addis Ababa from February 18, 2008–April 28, 2008. The study populations were parents/caretakers and children living with HIV/AIDS who were receiving Highly Active Antiretroviral Therapy (HAART) in selected hospitals in Addis Ababa. Univariate and multivariate logistic regression analysis were carried out using SPSS 12.0.1 statistical software.

Results

A total of 390 children/caretaker pairs were included in the study. Two hundred forty three children (62.3%) were between 6–9 years of age. HIV/AIDS status was known by 68 (17.4%) children, 93 (29%) caretakers reported knowing the child''s serostatus two years prior to our survey, 180 (46.2%) respondents said that the child should be told about his/her HIV/AIDS status when he/she is older than 14 years of age. Children less than 9 years of age and those living with educated caregivers are less likely to know their results than their counterparts. Children referred from hospital''s in-patient ward before attending the HIV clinic and private clinic were more likely to know their results than those from community clinic.

Conclusion

The proportion of disclosure of HIV/AIDS diagnosis to HIV-infected children is low. Strengthening referral linkage and health education tailored to educated caregivers are recommended to increase the rate of disclosure.     

The Relationship Between Scientific Knowledge and Behaviour: An HIV/AIDS Case

Debates on the role of scientific knowledge to affect behaviour are continuing. The theory of planned behaviour suggests that behaviour is influenced by attitudes, subjective norms and perceived behavioural control and not by knowledge. However, a large body of knowledge argues that increased HIV/AIDS-related knowledge leads to the adoption of safe behavioural practices. The purpose of this non-experimental survey study, therefore, was to investigate the correlation between academic HIV/AIDS knowledge, functional HIV/AIDS knowledge and self-reported behavioural preferences of 300 biology and 243 non-biology students from nine South African schools. Results suggest a correlation between students’ understanding of academic and functional HIV/AIDS knowledge. The behavioural preferences of both biology and non-biology students were generally the same and safe. Among biology students, correlation was observed between academic HIV/AIDS knowledge and self-reported safe behavioural preferences, which was not the case for non-biology students, where functional HIV/AIDS knowledge correlated with self-reported safe behavioural preferences. Within schools, however, no correlation was found between both forms of HIV/AIDS knowledge and self-reported safe behavioural preferences. There were indications that context-specific local factors have a greater influence on behavioural preferences. These findings suggest that the type of knowledge that could influence behaviour is informed by context-specific dynamics.     

University students' knowledge of, and attitudes towards, hiv and AIDS, homosexuality and sexual risk behaviour: a questionnaire survey in two finnish universities

Summary This study describes Finnish university students' knowledge and attitudes towards HIV and AIDS, homosexuality and sexual risk behaviour. Finnish-speaking students were randomly selected from all registered students at two universities in Finland (N=9715, n=950). The data were collected by using a modified version of the State University of New York at Buffalo School of Nursing AIDS Study Questionnaire on sexual risk behaviour developed by Held and Chng. The total response rate was 35% (n=333). The data were analysed using quantitative statistical methods. Normally distributed data were analysed by t-test and one-way ANOVA, with Bonferroni corrections. Non-normally distributed data were analysed using the Mann-Whitney U-test and Kruskal-Wallis test, followed by a post-hoc test. The majority of students were familiar with HIV and AIDS, including its mode of transmission. However, there were still some misconceptions concerning HIV and AIDS. The oldest students and women had a more positive attitude towards people living with HIV and AIDS (PLWHA). Of patients with HIV or AIDS, intravenous drug users were perceived most negatively. Male students had more homophobic attitudes. Students who reported that religion had an important role in their lives had significantly stricter attitudes towards sexual risk behaviour. Students' knowledge correlated positively with general attitudes towards HIV and AIDS. Knowledge about HIV and AIDS will lead to more positive attitudes towards HIV and AIDS as a disease, towards those infected as well as homosexual people. There is a need to focus on preventive health care and sexual health promotion by educating young people and changing their attitudes towards sexual risk behaviour.     

Through a glass, darkly: data and uncertainty in the AIDS debate

The HIV/AIDS epidemic is the greatest threat to development in much of Africa. It is already the main cause of death in many countries, especially those in Southern Africa. However there is an absence of solid data on the scale and scope of the disease and how it is evolving. In this article we discuss the data on the epidemic – where it comes from and how it is presented. We note the limitations of the use of antenatal clinic surveys – which provide the bulk of our information.
We then turn to the evidence of impact. The paper shows that the long incubation period between infection and illness means that it takes time for HIV infections to turn into AIDS cases, and AIDS cases to translate into deaths with all the consequences of orphaning, poverty and changing population structures. Furthermore it means that once the HIV prevalence has peaked, AIDS impact will take years to work through – this epidemic is a 'long-wave' event.
The paper is premised on the view that HIV causes AIDS and AIDS causes death. It notes that insufficient and/or unreliable data have allowed leaderships to deny the scope and scale of the problem and that this is unacceptable. However it is incumbent on all to accept the moral responsibility for and the moral consequences of their work, and this includes those who gather, interpret and use the data.
