Using ARVs as Prevention: Promise, Precautions and Potential for Drug Resistance

PrEP is a promising HIV prevention approach that involves use of antiretroviral (ARV) drugs that are normally used for treatment of HIV. But, should clinical trials find the strategy successful and PrEP is then rolled out as a prevention approach in at-risk communities, there is concern that virus resistant to the ARVs potentially would emerge and spread. What exactly is the risk and how can we avoid the consequences of "two trains on a collision course"? Two studies looked for answers. In one, a computer model that simulated the impact of PrEP on HIV prevention and drug resistance identified key factors that would influence the spread of HIV drug resistance. In a different take, laboratory studies suggest under what circumstances ARV-based gels could cause virus to become resistant. The same study tested different ARV gels to determine whether they can protect against strains of resistant virus known to be resistant against these ARVs or drugs in the same class.

Use of Lubricants, Unprotected Anal Sex and the Risk of HIV

Could the use of lubricants at least certain kinds be another risk factor among men and women who engage in receptive anal intercourse? A study involving nearly 900 men and women in Baltimore and
