HIV/AIDS misconceptions may be associated with condom use among black South Africans: An exploratory analysis

In South Africa, approximately 20% of 15-49-year-olds are infected with HIV. Among black South Africans, high levels of HIV/AIDS misconceptions (e.g. HIV is manufactured by whites to reduce the black African population; AIDS is caused by supernatural forces or witchcraft) may be barriers to HIV prevention. We conducted a cross-sectional study of 150 young black adults (aged 18-26;56% males) visiting a public clinic for sexually transmitted infections, to investigate whether HIV/AIDS misconceptions were related to low condom use in main partner relationships. We assessed agreement with HIV/AIDS misconceptions relating to the supernatural (e.g. witchcraft as a cause of HIV) and to genocide (e.g. the withholding of a cure). In multivariate models, agreement that 'Witchcraft plays a role in HIV transmission' was significantly related to less positive attitudes about condoms, less belief in condom effectiveness for HIV prevention, and lower intentions to use condoms among men. The belief that 'Vitamins and fresh fruits and vegetables can cure AIDS' was associated with lower intentions among men to use condoms. Women who endorsed the belief linking HIV to witchcraft had a higher likelihood of unprotected sex with a main partner, whereas women who endorsed the belief that a cure for AIDS was being withheld had a lower likelihood of having had unprotected sex. Knowledge about distinct types of HIV/AIDS misconceptions and their correlates can help in the design of culturally appropriate HIV-prevention messages that address such beliefs.

An in vitro and in vivo study of cytokines in the acute-phase response associated with bisphosphonates.

We studied the acute phase response, including specific cytokine production, [interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor alpha(TNF alpha)] following a single dose of Aredia (disodium pamidronate) in patients with increased bone turnover and, in vitro, the role played by specific cytokines in the acute-phase reaction which may follow the administration of aminobisphosphonates. An in vivo exploratory study was done on 24 in- and outpatients with increased bone turnover given a single intravenous dose of pamidronate 60 mg. Measurements were taken at baseline and at 24, 48, and 72 hours. The main outcome measures were changes from baseline in serum IL-1, IL-6, and TNF alpha. In addition, C-reactive protein (CRP), white blood cell count (WCC), lymphocyte count, and elastase concentration were measured. Symptomatic evaluation was made of fever, bone pain, and rigors. In vitro, whole blood from eight healthy volunteers was exposed to various concentrations of the three bisphosphonates--pamidronate, clodronate, and zoledronate. Measurements were taken immediately before and at 3, 6, and 10 hours after exposure to drugs. The main outcome measures were changes in serum IL-1, IL-6, and TNF alpha. In vivo, there was a statistically significant (P < 0.001) increase in median values of TNF alpha in all post-baseline measurements. Median values for IL-6 also showed a significant (P < 0.001) increase at 24 hours after dosing. There were no statistically significant changes in median IL-1 values. Few patients showed any change from baseline in total WCC or in lymphocyte count, but 62.5% of patients with normal range baseline values for CRP increased to above normal levels after treatment. Fourteen patients experienced fever; 2 reported rigors. There was no correlation between fever and changes in cytokines. There were no serious adverse experiences or premature discontinuations due to poor tolerability, and 91% of the patients expressed willingness to receive pamidronate again. In vitro, an increase in TNF alpha and a mild increase in IL-6 was seen with all bisphosphonates, with the greatest effects seen with the highest concentration of both pamidronate and zoledronate. No changes were observed in IL-1 with any agent. Significant changes in both TNF alpha and IL-6 were observed within 3 days of a single dose of pamidronate in patients treated for the first time confirming previous findings. However, the lack of change in IL-1 in vivo and in vitro does not support the hypothesis that this cytokine plays a major role in the acute phase reaction. The cellular mechanism of the interaction among aminobisphosphonates, IL-6, and TNF alpha requires further investigations. The results of the in vitro study are consistent with the in vivo findings

Programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in Africa, Central/Eastern Europe and Central Asia, Latin America, and the Caribbean

This study assessed the programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in 75 countries in Africa, Central/Eastern Europe and Central Asia, Latin America and the Caribbean. Multiple databases and expert recommendations were used to identify one major HIV-prevention NGO in the capital or a large city in each country, and in-depth interviews were conducted with each NGO Director. Most NGOs are carrying out their programmes with minimal funding and few regularly employed personnel. Most are highly dependent on international donors, but reliance on small grants with short funding periods limits programme development capacity. HIV-prevention activities varied by region, with African NGOs most likely to use peer education and community awareness events; Eastern European NGOs most likely to offer needle exchange; Latin American NGOs to have resource centres and offer risk reduction programmes; and Caribbean organizations to use mass education approaches. Across regions, NGOs most often targeted the general public and youth, although specialized at-risk groups were the additional focus of attention in some regions. Limited funding, governmental indifference or opposition, AIDS stigma, and social discomfort discussing sex were often cited as barriers to new HIV-prevention programmes. NGOs are critical service providers. However, their funding

HIV Prevention In Africa: Programs and Populations Served by Non-Governmental Organizations

The AIDS epidemic in Africa remains an urgent health crisis. Non-governmental organizations (NGOs) in Africa play a critical role in the delivery of HIV prevention services and assistance to persons living with AIDS. African NGOs are conducting numerous HIV prevention programs with several at-risk populations, yet their efforts have only rarely been systematically documented. To address this gap in the literature, the authors surveyed one NGO in each of 29 African countries regarding their HIV prevention activities and populations served. This report provides details concerning HIV prevention activities across the continent and describes in detail innovative programs from Togo and South Africa. NGOs in the present sample operate with modest budgets and small staff sizes, yet conduct programs that reach large segments of their communities. NGOs were most likely to report community-level interventions such as peer-education or community outreach. Faced with an epidemic where the main transmission occurs via heterosexual activity, African NGOs were most likely to direct their attention to the general public and to youth. NGOs in Africa are struggling to implement sustainable, cost-effective programs with few resources. Strengthening the infrastructure and capacity of these key agencies is crucial to fighting the AIDS epidemic in Africa

HIV prevention programs of nongovernmental organizations in Latin America and the Caribbean: the Global AIDS Intervention Network project

OBJECTIVE: The objective of this paper is to describe HIV prevention programs conducted by nongovernmental organizations (NGO) that are meeting this challenge. METHODS: One NGO undertaking HIV prevention programs was evaluated in each of the 23 countries participating in the Global AIDS Intervention Network (GAIN) Project throughout Latin America and the Caribbean. A two-stage selection process was used: (1) a search in databases and other information sources; (2) identification of NGOs that were best established and most actively engaged in HIV prevention activity. Executive directors were questioned about staffing, budget issues, populations served and barriers faced by these entities. RESULTS: The 23 NGOs conducted 58 direct-service programs and had been conducting HIV prevention activities for a mean of 8 years (SD=4.45; range 1-18 years). Average annual program budget was US $205,393 (range: US$10,000 to US $1,440,000). The NGOs reported a mean of 4.5 full-time employees (range 0-15, SD=4.7). Many relied on volunteers (median=10, mean=51, range 0-700, SD=150) to conduct HIV prevention activities. The NGOs provided prevention services for the general community (82.6%), children and adolescents (34.8%) and men who have sex with men (30.4%). Activities conducted by NGOs included train-the-trainer activities (43.5%) and face-to-face prevention activities (34.8%). Obstacles cited included lack of funding (60.9%) and HIV-related stigma and discrimination (56.5%). CONCLUSION: The strategies used by NGOs to overcome barriers to prevention are a testament to their ingenuity and commitment, and serve as examples for NGOs in other world regions

Distance Communication Transfer of HIV Prevention Interventions to Service Providers

Most acquired immunodeficiency syndrome (AIDS) service providers are in countries with little access to scientific developments relevant to their programs. It is critical to transfer advances from the scientific arena to service providers on a global scale. Human immunodeficiency virus (HIV) prevention organizations in 78 countries were randomized to receive either a control condition or a technology transfer condition with an interactive distance learning computer training curriculum and individualized distance consultation. Of 42 nongovernmental organizations in the technology transfer condition, 29 adopted the science-based program in their communities or trained other agencies to also use it. Advanced communication technologies can create a cost-effective infrastructure to disseminate new intervention models to service providers worldwide

The NGOs provided prevention services for the general community (82.6$ 205 393 (intervalo de US$10 000 a US$ 1 440 000), y el número promedio de empleados a tiempo completo era de 4,5 (intervalo de 0-15, DE = 4,7.) Muchas ONG dependían de los voluntarios para los programas de prevención (mediana = 10, promedio = 51, intervalo de 0-700, DE = 150). Las ONG ofrecían programas de prevención dedicados a la comunidad en general (82,6%), a jóvenes y adolescentes (34,8%), y a hombres que tienen relaciones sexuales con otros hombres (30,4%). Las actividades de las ONG consistían en entrenar a los entrenadores para todo tipo de actividades (43,5%) y en realizar programas de prevención cara a cara con los participantes (34,8%). Se citaron como obstáculos la falta de fondos (60,9%) y la discriminación y estigma relacionados con la infección por el VIH (56,5%). CONCLUSIONES: Las estrategias que emplean estas ONG para sobrepasar las barreras a la prevención son prueba de su inventiva y dedicación y sirven como ejemplo para las ONG en otras regiones del mundo
