Some Men Shed HIV in Semen Despite ART, Linked to Herpesvirus Coinfection

About 10% of gay men in a U.S. study had detectable HIV in their semen despite suppression of blood plasma viral load with antiretroviral therapy (ART), which has implications for HIV transmission, according to a study described in the April 17, 2013, advance online edition of Clinical Infectious Diseases. Having a low but detectable blood viral load and coinfection with cytomegalovirus or Epstein-Barr virus were associated with increased likelihood of semen HIV shedding.

The report also notes that AIDS-related deaths and new HIV infections have both fallen by about 30% over the past decade.  alt

 

Very Early Antiretroviral Therapy Does Not Prevent Immune Activation

People who started antiretroviral therapy (ART) during acute HIV infection and experienced sustained viral suppression saw a substantial decrease in immune activation markers on their CD8 T-cells after 2 years of treatment, but often not to the level seen in HIV negative individuals, according to a report in the April 15, 2013, Journal of Acquired Immune Deficiency Syndromes.

Sangamo Reports Zinc Finger Gene Therapy Leads to Long-term CD4 Cell Gains, Shrinking HIV Reservoirs

An experimental gene therapy technique that modifies CD4 T-cells to protect them from viral entry produced lasting CD4 cell increases with a single infusion, as well as reduction in proviral DNA reservoirs and decreased viral load in 2 patients who underwent antiretroviral therapy (ART) interruption, according to data presented this week at the 16th Annual Meeting of the American Society of Gene and Cell Therapy in Salt Lake City.

Efavirenz More Effective than Nevirapine for Children with HIV

HIV positive African children and adolescents treated with efavirenz (Sustiva) were less likely to experience virological failure than those using nevirapine (Viramune), according to a large comparative study published in the May 1, 2013, Journal of the American Medical Association. Nevirapine, however, is less expensive and more widely available for children in low-income countries.
