Conference News

  • "Prevention Cocktail" Needed to Reduce HIV Incidence Among MSMA combination of individual and community interventions may help decrease HIV incidence among men who have sex with men.
  • Gut Fibrosis Affects CD4+ Depletion and RepletionDepletion of CD4+ T cells during HIV infection, and their subsequent replacement after antiretroviral therapy, may be affected by fibrosis in the gut.
  • Scientific Obstacles to Effective HIV Vaccine Frustrate ResearchersTo overcome these obstacles, one expert recommends research focusing on broadly neutralizing antibodies and more aggressive pursuit of novel vaccine concepts, among other strategies.
  • Vaginal Lactobacillus Protects Against HIVLactobacillus, a key regulator of the vaginal ecosystem, also significantly reduces HIV-1 load in the vaginal tract, either directly or by suppression of pathogenic bacteria, investigators reported at the 15th Conference on Retroviruses and Opportunistic Infections here this week.
  • HIV Resistance Level Higher in Poor CountriesAlthough HIV-infected patients in resource-rich and resource-poor countries have comparable rates of compliance and response to first-line highly active antiretroviral therapy (HAART), there are disparities in the development of viral resistance to treatment.
  • Second Schering CCR5 Antagonist Shows Potency in Phase 1 TrialA phase 1 trial of SCH532702, a chemokine receptor 5 antagonist, demonstrated a profile of safety, pharmacokinetics, and viral suppression that justifies continued development.
  • Vicriviroc Data Lead to Phase 3 TrialData from the VICTOR E-1 study indicate that vicriviroc can act against HIV in treatment-experienced patients.
  • Some Adverse Effects of HIV Therapy Interruption PersistThe negative consequences of interrupting highly active antiretroviral therapy of HIV infection decrease after treatment resumes, but they do not return to pre-interruption levels, investigators reported here at the 15th Conference on Retroviruses and Opportunistic Infections.
  • Maternal HAART Reduces Breast Milk-Related HIV InfectionHIV transmission is significantly reduced in infants born to HIV-infected mothers who are on highly active antiretroviral therapy (HAART), when the infants are given a standard single-dose of nevirapine at birth, according to a 4-year study conducted in Kenya.
  • Extended Infant Prophylaxis Reduces HIV Transmission Via BreastfeedingUp to 50% of postnatal HIV infections from breastfeeding can be prevented by extending the standard nevirapine prophylaxis regimen, African and Indian investigators working in resource-poor settings reported Monday.
  • Circumcision Reduces Heterosexual Transmission of HSV-2 but Perhaps Not HIVIn a nested study, circumcision reduced the transmission of herpes simplex virus 2 but did not have an effect on the transmission of HIV.
