CROI 2015: PrEP Provides 86% Protection in 2 Studies [VIDEO]

Among the most eagerly anticipated and well received news at the 2015 Conference on Retroviruses and Opportunistic Infections(CROI) last week in Seattle were a pair of reports showing that Truvada (tenofovir/emtricitabine) pre-exposure prophylaxis, or PrEP, taken either daily or before and after sex, reduced the likelihood of HIV infection by 86%. In both studies, no one who took PrEP consistently became infected.

CROI 2015: Smoking Outweighs HIV-Related Risk Factors for Non-AIDS Cancers

Smoking appears to contribute most to the burden of non-AIDS-defining cancers diagnosed in people living with HIV in the U.S., out of all the potential modifiable risk factors -- including hepatitis B or C, low CD4 cell count, an AIDS diagnosis, or having an unsuppressed viral load -- according to a study reported last week at the 2015 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle.

CROI 2015: Smoking and Its Detrimental Outcomes for People with HIV

Smoking and its consequences was a major topic at the 2015 Conference on Retroviruses and Opportunistic Infections (CROI) last week in Seattle. Researchers presented findings on smoking as a risk factor for cancer, CT scans to detect early lung cancer, and varenicline for smoking cessation.

CROI 2015: Screening Finds High Prevalence of Early-Stage Lung Cancer in Smokers with HIV

Using low-dose computed tomography to screen selected people living with HIV who smoke led to early lung cancer diagnoses at younger ages than normally seen in the general population, according to findings from the ANRS EP48 HIV CHEST study reported last week at the 2015 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle.

CROI 2015: HIV Attachment Inhibitor BMS-663068 Shown Safe and Effective in Phase 2b Study

Bristol-Myers Squibb's BMS-663068 or fostemsavir, a first-in-class HIV attachment inhibitor that stops the virus from binding to and entering cells, was well-tolerated and demonstrated good antiviral activity in a study presented at the 2015 Conference on Retroviruses and Opportunistic Infections (CROI) last week in Seattle. Related research showed that BMS-663068 can safely be taken with antiretrovirals commonly used by treatment-experienced patients. A Phase 3 trial is now underway.

CROI 2015: Varenicline Helps People with HIV Stop Smoking, but Success Rate Remains Low

The smoking cessation drug varenicline (Chantix) helped more people with HIV to stop smoking than counseling alone, but less than 20% were able to remain abstinent for a year, according to the results of a French study presented at the 2015 Conference on Retroviruses and Opportunistic Infections (CROI) last week in Seattle.The smoking cessation rates in this study were comparable to those previously seen for HIV-negative people using varenicline or other methods -- across the board only a minority manage to quit long-term.

CROI 2015: Treatment Cascades and Viral Load Surveys Inform ART as Prevention in Africa

Reaching ambitious HIV prevention targets in South Africa will require intensified efforts to engage and retain men and young people in care, in order to increase the proportion of people on HIV treatment with suppressed viral load, according to a national study presented at the Conference on Retroviruses and Opportunistic Infections (CROI 2015) last week in Seattle. Another study, conducted in 3 countries in sub-Saharan Africa, showed that to maximize the preventive effect of antiretroviral therapy (ART), efforts to expand treatment coverage need to focus on those with the highest viral load off treatment -- mainly people who are already eligible for treatment under current guidelines.
