Abstract

Raltegravir is the first integrase strand transfer inhibitor approved for treating HIV-1 infection. Although emerging data suggest that raltegravir may also be useful for HIV-2 treatment, studies addressing the in-vitro susceptibility of HIV-2 to raltegravir are scarce, and the genetic pathways leading to raltegravir resistance in HIV-2 have not been adequately characterized. Our objectives were to directly compare the susceptibilities of HIV-1 and HIV-2 to raltegravir and to examine the role of mutations in HIV-2 integrase in emergent raltegravir resistance.
