Transient increment of HTLV-2 proviral load in HIV-1- coinfected patients during treatment intensification with raltegravir

Online publication: 09/01/2014

Abstract:

BackgroundNumerous studies have analyzed the effects of raltegravir intensification on HIV-1 viral replication in infected individuals receiving suppressive combined antiretroviral treatment (cART). Nevertheless, there are only two studies on the effect of raltegravir in HTLV-1 infection, and none in HTLV-2. ObjectiveTo study the effect of raltegravir on HTLV-2 infection in HIV-1-co-infected individuals. Study designThis retrospective longitudinal study included four HTLV-2-HIV-1-co-infected individuals who received raltegravir-based cART during 48 weeks and 11 HTLV-2-HIV-1-co-infected individuals under cART without raltegravir during 48 weeks. HTLV-2 proviral load, CD4 and CD8 count and frequency were analyzed. ResultsHTLV-2 proviral load significantly increased at week 24 compared to baseline among all the patients who received raltegravir (p = 0.003), while no significant increases were found in the control group. No significant variation in either CD8 or CD4 counts was found during the follow up in both groups. ConclusionsRaltegravir induced a transient increment on total HTLV-2 DNA proviral load in HTLV-2/HIV-1-coinfected individuals on suppressive cART after 24 weeks. Read abstract online
