Although younger children with HIV are at high risk of disease progression if not treated, new research published this week in PLOS Medicine indicates that they have good potential for achieving high CD4 counts (a measure of a type of white blood cell that correlates with immune function) in later life provided antiretroviral therapy (ART) is initiated according to current treatment guidelines. However, the research also suggests that the recommended CD4 count thresholds for ART initiation...

In many ways, the spread of HIV has been fueled by substance abuse. Shared needles and drug users' high-risk sexual behaviors are just some of the ways that narcotics such as cocaine have played a key role in the AIDS epidemic in much of the world. There is, however, relatively little research into how drugs can impact the body's defenses against the virus. But a new UCLA study published in the October issue of the Journal of Leukocyte Biology examines how cocaine affects a unique...

New research published in the Journal of Leukocyte Biology suggests that cocaine makes quiescent CD4 T cells susceptible to HIV resulting in significant infection and new virus production Cocaine use may increase one's vulnerability to HIV infection, according to a new research report published in the Journal of Leukocyte Biology. In the report, scientists show that cocaine alters immune cells, called "quiescent CD4 T cells," to render them more susceptible to the virus, and at the same...

HIV-infected people who carry a gene for a specific protein face a 20-fold greater risk of contracting cryptococcal disease, according to a study published in mBio®, the online open-access journal of the American Society for Microbiology. Cryptococcus neoformans is the most common cause of fungal meningitis among HIV-infected individuals. While the disease is a risk for everyone with HIV who has a very low level of CD4+ T cells, researchers have discovered that those with the gene for the...

In South Africa, people with HIV who start treatment with anti-AIDS drugs (antiretroviral therapy) have life expectancies around 80% of that of the general population provided that they start treatment before their CD4 count drops below 200 (cells per microliter), according to a study by South African researchers published in this week's PLOS Medicine. These findings are encouraging and show that with long-term treatment, HIV can be managed as a chronic illness in middle- and low-income...
