IntroductionEtravirine (ETR), a non‐nucleoside reverse transcriptase inhibitor available in France since 2006, is indicated for the treatment of HIV‐1 infection in combination with a ritonavir boosted protease inhibitor (PI) in antiretroviral treatment‐experienced adult patients. To assess its impact in routine clinical care, our objective was to compare hospitalization rates in highly pre‐treated failing HIV‐1 infected individuals between 2005 and 2011 depending on whether or not they received ETR+PI.MethodsFrom the French Hospital Database on HIV (ANRS CO4), we selected highly pre‐treated individuals (prior exposure to at least 2NRTI, 2PI and 1 NNRTI) with a viral load (VL)>50 copies/mL initiating a new regimen between 2005 and 2011. Hospitalization rates were calculated for each calendar month and depending on whether patients never received ETR+PI at any time or during months before initiating ETR+PI (no ETR+PI) or during months after initiating ETR+PI (ETR+PI), using an intention to continue treatment approach. Poisson regression models were used to compare incidence between the two groups, after adjustment for potential confounders (age, transmission group, origin, AIDS, PCP prophylaxis, viral load, CD4, nb of previous ARV).ResultsOverall 3884 patients fulfilled inclusion criteria. Among them 838 (21.6%) received ETR+PI at least once. Among all enrolled patients, 35.8% had CD4 <200/mm3, 17.5% had VL >100,000 copies/ml, 42.8% had had an AIDS event and 47.8% had received more than 10 different antiretroviral drugs. There were 2484 hospitalizations in 808 individuals over 13,986 patient‐years. The hospitalization rates for 1000 P‐Y were 169.0 for the ETR+PI group and 179.3 for the no ETR+PI group. After adjustment, the corresponding figures were 144.8 for 1000 P‐Y and 192.7 for 1000 P‐Y respectively, with a relative risk estimated as 0.75 (95% CI 0.67–0.84).ConclusionsAccess to ETR+PI between 2005 and 2011 was associated with a 25% reduction in the hospitalization rate among highly pre‐treated failing HIV‐1 infected individuals.

IntroductionA key objective of combined antiretroviral therapy (cART) is to reach and maintain high CD4 cell counts to provide long‐term protection against AIDS‐defining opportunistic infections and malignancies, as well as other comorbidities. However, a high proportion of patients present late for care. Our objective was to assess CD4 cell count recovery up to seven years in naïve patients initiating cART with at least three drugs in usual clinical care.MethodsFrom the French Hospital Database on HIV, we selected naïve individuals initiating cART from 2000 with at least two years of follow‐up. Participants were further required to have achieved viral load suppression by six months after initiating cART and were censored in case of virological failure. We calculated the proportion of patients (Kaplan‐Meier estimates) who achieved CD4 recovery to >500/mm3 according to baseline CD4 cell count.ResultsA total of 15,025 patients were analyzed with a median follow‐up on ART of 65.5 months (IQR: 42.3–96.0). At cART initiation, the median age was 38.6 years (IQR: 32.2–46.0), 9734 (64.8%) were men, median CD4 cell count was 239 (IQR: 130–336) and 2668 (17.8%) had a prior AIDS event. Results are presented in the Table 1.

ConclusionsThis study shows that CD4 cell counts continue to increase seven years after cART initiation, whatever the baseline CD4 cell count. Failing to achieve CD4 recovery with continuous viral load suppression is rare for naïve patients initiating cART in routine clinical practice, but takes substantially longer in patients who initiate antiretroviral therapy at low CD4 cell counts.
