Study Sheds New Light on What Happens During Acute HIV Infection

An individual's HIV viral load set-point is generally reached about a month after plasma viremia is first detectable, according to an analysis published in the May 18 online edition of the New England Journal of Medicine. The RV217 study, which included more than 100 people with acute HIV infection in East Africa and Thailand, found that signs and symptoms were uncommon during the earliest stages of infection, and what happens during this period influences later disease progression.

EACS 2015: Does Low-level HIV Viral Load Raise the Risk of Disease Progression and Comorbidities?

HIV-positive people with detectable but low viral load -- in the range of 50 to 500 or 1000 copies/mL -- may continue to have a higher risk of AIDS-related events, but their likelihood of experiencing serious non-AIDS events including heart, liver, and kidney disease did not appear to increase, according to a pair of Italian studies presented at the 15th European AIDS Conference last month in Barcelona.

IAS 2015: Altered Cholesterol Metabolism May Protect Immune Cells of Non-Progressors

Enhanced cholesterol metabolism in certain immune cells may help explain why some people with HIV can naturally control the virus with little or no disease progression, according to research presented at the 8th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention and at the preceding IAS Towards an HIV Cure Symposium last month in Vancouver. The findings suggest that regulating cellular cholesterol metabolism may offer a new approach to controlling HIV and potentially achieving a functional cure, or long-term remission.

IAS 2015: Many People with Long-term HIV Infection Do Not Achieve Full CD4 Cell Recovery

One-third of people who started combination antiretroviral therapy (ART) many years ago using first-generation protease inhibitors did not achieve complete immunological recovery with normal CD4 T-cell counts despite good viral suppression, according to a French study presented at the recent 8th International AIDS Society Conference on HIV Pathogenesis, Treatment, and Prevention in Vancouver.

IAS 2015: International AIDS Society Conference Starts this Weekend in Vancouver

The 8th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2015) starts this Sunday and runs July 19-22 in Vancouver. HIV prevention -- including treatment-as-prevention and pre-exposure prophylaxis (PrEP) -- will be a major focus of the meeting. Other topics will include antiretroviral drugs in development, expanding access to treatment and retention in care, and HIV/hepatitis coinfection. HIVandHepatitis.com will be on site covering the latest news.
