New CDC Guidelines: People at Risk for HIV Should Consider Truvada PrEP

Healthcare providers should advise people at "substantial risk" for HIV infection about pre-exposure prophylaxis (PrEP) using tenofovir/emtricitabine, or Truvada, according to new guidelines issued by the U.S. Centers for Disease Control and Prevention (CDC). This includes HIV negative people in an ongoing sexual relationship with HIV positive partners, gay or bisexual men who have had sex without condoms during the past 6 months, heterosexual men and women who have sex without condoms with at-risk partners, and injection drug users.

Earlier Antiretroviral Therapy Lowers Risk of Progression to AIDS and Related Conditions

Starting antiretroviral therapy (ART) at higher CD4 cell levels can significantly reduce the risk of AIDS-related clinical events, especially tuberculosis, as well as dramatically reducing the likelihood of HIV sexual transmission, according to findings from the HPTN 052 study published in the April 2014 issue of Lancet Infectious Diseases.

Coral Proteins Block HIV from Entering Cells, May Be Useful in Microbicides

A set of proteins derived from soft coral identified from a National Cancer Institute repository of biological chemicals can bind to HIV and prevent it entering immune cells, suggesting it may have potential for use in microbicide gels or other products to prevent transmission of the virus, according to a poster presented at the Experimental Biology 2014 meeting last week in San Diego.

Harm Reduction Program Reduces Meth Use and HIV Risk Behavior Among Gay Men

Participants in the Stonewall Project, a harm reduction-based substance use program, reduced their use of methamphetamine and cocaine and engaged in less risky sexual behavior that could lead to HIV transmission, according to a pair of studies described in the April 14 online edition of the Journal of Urban Health.

Updated Antiretroviral Treatment Guidelines Include Cost Considerations

The U.S. Department of Health and Human Services (DHHS) this week released an update to its Guidelines for the Use of Antiretroviral Agents in HIV-1-Infected Adults and Adolescents. Among the major changes are the addition of a new section on cost considerations and a recommendation for less frequent CD4 T-cell monitoring for people without advanced disease.

Human Papillomavirus Vaccine Is Effective for Women with HIV

HIV positive women respond well to the Gardasil human papillomavirus (HPV) vaccine, offering them protection against cervical cancer, according to a study published in the April 14 electronic edition of Clinical Infectious Diseases. Related recent research found that both Gardasil and Cervarix are effective in people with HIV.

Inherited Low Cholesterol in Immune Cells Linked to Slower HIV Disease Progression

A genetic variation linked to lower levels of intracellular cholesterol is associated with reduced transmission of HIV between immune cells, which may contribute to slower evolution of disease in non-progressors, according to a report in the April 29, 2014, edition of the electronic journal mBio, published by the American Society for Microbiology.
