Surprising Results For Ugandan HIV Intervention Trial (pp 633, 645)February 19, 2003Results of a study in this week's issue of THE LANCET show how interventions to promote safer sex and the control of sexually transmitted diseases did not reduce the incidence of HIV infection in an area of rural Uganda. Treatment of sexually transmitted infections (STIs) and behavioural interventions are the main methods to prevent HIV in developing countries. Anatoli Kamali from the Medical Research Council Programme on AIDS in Uganda and colleagues assessed the effect of behaviour change and STI management on the incidence of HIV-1 and other STIs in Uganda. All adults living in 18 communities in rural Uganda were randomly allocated into three groups: the first group received behavioural interventions alone (promotion of safer sex behaviour); the second group received both behavioural and STI interventions; the third was a control group where individuals received routine government health services and community development activities. Follow-up took place after three and a half to four years. Only condom use with last casual partner increased significantly more in the two intervention groups compared with the control group. Despite significant reductions in acute syphilis, gonorrhoea, and unprotected casual sex in the combined intervention group, there was no effect on HIV incidence attributable to either intervention. The investigators comment that more effective STI and behavioural interventions need to be developed for HIV control in mature epidemics in countries like Uganda. Judith Stephenson and Frances Cowan from the Royal Free and University College Medical School, London, UK, observe in an accompanying Commentary (p 633) that the timing of the study could partly explain the surprising results; the fact that the overall HIV incidence is falling in Uganda suggests that the study could have been underpowered to detect substantial differences in HIV incidence between the intervention and control groups. They conclude: "What does this trial tell us for the future? Rigorous evaluation of promising interventions should be encouraged early on when HIV incidence is rising and high-risk groups are readily identifiable. It is vital to know which approaches actually work and which do not. The evaluation of complex behavioural interventions is challenging, but expertise in this area is accumulating. The development, piloting, and full-scale evaluation of promising interventions is essential to the success of HIV prevention and should receive greater priority." Lancet |

AIDS research reveals a lack of family-planning programs in Uganda University of Alberta graduate student Jennifer Heys wants to make her message clear: there needs to be more education in Ugandan communities about contraception. Many pregnant women avoid HIV screening in Africa 'Prevention is the best cure' is a common expression, but what happens if preventative measures are not used? A large proportion of pregnant Ugandan women are going out of their way not to be HIV tested, increasing the risk of mother-to-child transmission. An atomic-level look at an HIV accomplice Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity. New findings suggest strategy to help generate HIV-neutralizing antibodies New discoveries about anti-HIV antibodies may bring researchers a step closer to creating an effective HIV vaccine, according to a new paper co-authored by scientists at the Vaccine Research Center of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Research calls for better assessment of tests for tuberculosis, HIV/AIDS and malaria A rapid and accurate diagnosis is the first step towards treatment in the fight against infectious disease. No-entry zones for AIDS virus The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for developing new, specific AIDS drugs. Hoping for a fluorescent basket case Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. Scientists explain binding action of 2 key HIV antibodies; could lead to new vaccine design A very close and detailed study of how the most robust antibodies work to block the HIV virus as it seeks entry into healthy cells has revealed a new direction for researchers hoping to design an effective vaccine. U.S. and European Experts Applaud Creation of New Transatlantic Task Force on Global Antibiotic Resistance Threat Experts on both sides of the Atlantic applaud President Barack Obama and Swedish Prime Minister Fredrik Reinfeldt, representing the European Union (EU) Presidency, for establishing a transatlantic task force to address antibiotic resistance, an urgent and growing problem that threatens patient safety and public health worldwide.
