Broad-Spectrum Killer T-Cells May Be Needed to Fight Latent HIV

Cytotoxic T-cells with a wide spectrum of activity may be necessary to detect and destroy memory CD4 T-cells containing inactive reservoir HIV from people who start antiretroviral therapy (ART) during chronic infection, according to research reported in the January 7 edition of Nature. People who start treatment very early, however, may still have non-mutated virus that is susceptible to detection by normal killer T-cells -- and a therapeutic vaccine may help boost immune responses in those treated later.

Southern States Have Higher HIV Diagnosis Rate and Lower HIV/AIDS Survival

A group of 9 states in the southern U.S. had a higher rate of HIV diagnosis compared to the country as a whole; had more women, African-Americans, and young people living with HIV; and had a higher death rate among people with HIV or AIDS, according to a study recently published in the Journal of Community Health. The researchers suggested that socioeconomic disadvantages, stigma, and discrimination contribute to these disparities.

Long-acting Injectable Cabotegravir Shows Promise as PrEP in Monkey Studies

A long-acting injected formulation of the HIV integrase inhibitor cabotegravir (GSK1265744) prevented infection of most macaque monkeys vaginally exposed to an HIV-like hybrid virus at drug concentrations achievable with monthly dosing, according to a pair of studies published in the January 14 issue of Science Translational Medicine.

Meta-Analysis Shows Injectable Hormonal Contraception Linked to HIV Infection Risk

Women who use the long-acting injectable contraceptive Depo-Provera had a modest but significant increase in the risk of contracting HIV infection, according to a meta-analysis of 12 studies published in the January 8Lancet Infectious Diseases. However, there was no increase in risk for women using birth control pills.

Low CD4 Count, Suboptimal HIV Treatment Linked to Higher Anal Cancer Risk

People with HIV who experienced extensive immune deficiency or who used early antiretroviral drugs before the advent of combination highly-active antiretroviral therapy (HAART) in the mid-90s may be at greater risk for developing anal cancer, according to a retrospective analysis published in the January 28 edition of AIDS.
