Johns Hopkins and Ugandan scientists say counting the number of HIV viruses in the blood rather than relying solely on counting the number of circulating HIV-fighting CD4 immune system cells is a far better way to uncover early signs that antiretroviral drugs are losing their punch, and to signal the need to get patients on more potent treatments to keep the disease in check.

To be included, programs must be scientifically proven to reduce HIV or STD-related risk behaviors, or promote safer behaviors.
Hospitals in states where Medicaid does not pay for routine male circumcision are only about half as likely to perform the procedure, and this disparity could lead to an increased risk of HIV infection among lower-income children later in life.

Immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, its disease fighting ability is compromised. But a chemical from the Astragalus root can prevent or slow the progressive telomere shortening, which could make it a key weapon in the fight against HIV.

A study published today online in The Journal of Experimental Medicine sheds light on the potential mechanisms responsible for the increased incidence of HIV infection that was observed in the failed STEP HIV vaccine trial in 2007. Through the development of an experimental in vitro model, the study shows that the immune complexes formed by antibodies and the adenovirus vector (the Trojan horse for the delivery of the vaccine) induce a strong activation signal of key cells, i.e. dendritic cells, responsible for the activation of the cellular arm of the immune response including CD4 T-cells, the primary target for HIV.
HIV-infected adults taking the antiretroviral drug efavirenz were more likely to adhere to treatment and less likely to experience virologic failure and death compared to patients taking nevirapine. Nevirapine is the most frequently prescribed drug for patients undergoing highly active antiretroviral therapy (HAART) for the treatment of HIV/AIDS in sub-Saharan Africa.
