ABSTRACT
BACKGROUND:
Etravirine (ETR), a non-nucleoside reverse transcriptase inhibitor (NNRTI) available in France since 2006, is indicated for antiretroviral-experienced HIV-infected adults, in combination with a ritonavir-boosted protease inhibitor (PI). To assess its clinical impact in routine care, we compared hospitalization rates according to ETR + PI prescription or not, among heavily treated HIV-1 infected individuals on failing regimens between 2005 and 2011.METHODS:
From the French Hospital Database on HIV (ANRS CO4), we selected heavily treated individuals (prior exposure to at least 2 nucleoside reverse transcriptase inhibitor (NRTI), 2PI and 1 NNRTI) with viral load (VL) > 50 copies/mL who started a new antiretroviral (ARV) regimen between 2005 and 2011. Using an intention-to-continue-treatment approach, hospitalization rates were calculated for the individuals who received ETR + PI, during the months after initiating ETR + PI (ETR + PI) or for the individuals who received ETR + PI, in the months before ETR + PI initiation and for the individuals who never received ETR + PI (no ETR + PI). hospitalization from an AIDS-defining cause and hospitalization from a non-AIDS defining cause rates were also calculated. Poisson regression models were used to compare the incidences between the two groups, with adjustment for potential confounders.RESULTS:
Of 3884 patients who met the inclusion criteria, 838 (21.6%) received ETR + PI. During 13,986 person-years (P-Y) of follow-up, there were 2484 hospitalizations in 956 individuals. The hospitalization rates per 1000 P-Y were 169.0 among individuals exposed to ETR + PI and 179.3 among those not exposed to ETR + PI. After adjustment, the respective hospitalization rates were 148.8 and 186.7 per 1000 P-Y, with an estimated relative risk of 0.80 (95%CI 0.71-0.90), AIDS hospitalization rates were 11.5 and 22.7 per 1000 P-Y, with an estimated relative risk of 0.51(95%CI 0.39-0.66) and non-AIDS hospitalization rates were 139.5 and 152.2 per 1000 P-Y, with an estimated relative risk of 0.92 (95%CI 0.80-1.05).CONCLUSIONS:
Between 2005 and 2011, access to ETR + PI was associated with a 20% reduction in the hospitalization rate among heavily treated HIV-1-infected individuals. This reduction was mainly due to a reduction in the AIDS hospitalization rate.Palavras-chave
