Response to Combined Antiretroviral Therapy According to Gender and Origin in a Cohort of Naive HIV-Infected Patients: GESIDA-5808 Study

We analyzed differences in response to combined antiretroviral therapy (cART) according to sex and geographic origin in a retrospective comparative study of Spanish-born and immigrant patients initiating cART. The primary endpoint was time to treatment failure (TTF), defined as virological failure, death, opportunistic infection, interruption of cART, or loss to follow-up. Late diagnosis was defined as a CD4+ cell count ≤ 200 cells/mm3 and/or AIDS at initiation of cART. Survival was analyzed using Kaplan-Meier analysis and Cox regression. We followed 1,090 patients, of whom 318 were women (45.6% immigrant women [IW]). At initiation of treatment, women had a higher CD4+ count than men (217 vs 190 cells/mm3), a lower viral load (4.7 vs 5 log), and fewer were late starters (49% vs 59%). The adjusted risk of TTF between women and men was not significantly different (hazard ratio [HR], 1.10; 95% CI, 0.79-1.53). TTF was shorter among IW than Spanish-born women (124 weeks [95% CI, 64-183] vs 151 [95% CI, 127-174]) and loss to follow-up was double that of Spanish-born women (25.5% vs 11.6%). Although response to cART was similar for both sexes, men started treatment later. IW were more frequently lost to follow-up and switched treatment. Measures to improve medical follow-up after initiation of cART should be promoted among this minority group.

Do HIV-Infected Immigrants Initiating HAART have Poorer Treatment-Related Outcomes than Autochthonous Patients in Spain? Results of the GESIDA 5808 Study

Objective: Currently, 12% of the Spanish population is foreign-born, and a third of newly diagnosed HIV-infected patients are immigrants. We determined whether being an immigrant was associated with a poorer response to antiretroviral treatment. Methods: Historical multicenter cohort study of naive patients starting HAART. The primary endpoint was time to treatment failure (TTF) defined as virological failure (VF), death, opportunistic disease, treatment discontinuation (D/C), or missing patient. Secondary endpoints were TTF expressed as observed data (TFO; censoring missing patients) and time to virological failure (TVF; censoring missing patients and D/C not due to VF). A multivariate analysis was performed to control for confounders. Results: A total of 1090 treatment-naive HIV-infected patients (387 immigrants and 703 autochthonous) from 33 hospitals were included. Most immigrants were from Sub-Saharan Africa (28.3%) or South-Central America/Caribbean (31%). Immigrants were significantly younger (34 y vs 39 y), more frequently female (37.5% vs 24.6%), with less HCV coinfection than autochthonous patients (7% vs 31.3%). There were no differences in baseline viral load (4.95 Log(10) vs 4.98 Log(10)), CD4 lymphocyte count (193.5/mu L vs 201.5/mu L), late initiation of HAART (56.4% vs 56.0%), or antiretrovirals used. Cox-regression analysis (HR; 95%CI) did not show differences in TTF (0.89; 0.66-1.20), TFO (0.95; 0.66-1.36), or TVF (1.00; 0.57-1.78) between immigrants and autochthonous patients. Losses to follow-up were more frequent among immigrants (17.8% vs 12.1; p=0.009). Sub-Saharan African patients and immigrant females had a significantly shorter TTF. Conclusions: The response to HAART among immigrant patients was similar to that of autochthonous patients, although they had a higher rate of losses to follow-up. Sub-Saharan Africans and immigrant females may need particular measures to avoid barriers hindering antiviral efficacy.1.923 JCR (2010) Q3, 23/33 Virology; Q4, 103/134 Immunology, 44/58 Infectious Disease

Effect of accompanying antiretroviral drugs on virological response to pegylated interferon and ribavirin in patients co-infected with HIV and hepatitis C virus

The effects of antiretroviral drugs on the response to pegylated interferon plus ribavirin remain uncertain. We evaluated whether antiretroviral drugs affected the response to pegylated interferon plus ribavirin in patients co-infected with HIV and hepatitis C virus (HCV). We conducted a retrospective analysis of two cohorts of HIV/HCV-co-infected patients treated with pegylated interferon plus ribavirin between 2001 and 2007 in Spain. The outcome measure was sustained virological response (SVR). Logistic regression models were used to test possible associations between non-response and pre-treatment characteristics, including accompanying antiretroviral drugs. The study sample comprised 1701 patients: 63% were infected with HCV genotype (G) 1 or 4 and 88% were taking highly active antiretroviral therapy (HAART). Factors independently associated with increased odds of SVR were G2 or 3, HVC RNA <500,000 IU/mL and CDC clinical category A or B. When we adjusted for these prognostic factors and dose of ribavirin/kg, the adjusted odds ratio (AOR) of SVR for patients without HAART was 1.31 [95% confidence interval (CI) 0.91-1.88; P = 0.144]. Taking the backbone of tenofovir and lamivudine/emtricitabine as a reference, we found that, with the exception of regimens including zidovudine, the effect of other nucleoside reverse transcriptase inhibitor backbones had little effect on SVR. The AOR of SVR for zidovudine and lamivudine was 0.65 (95% CI 0.46-0.93, P = 0.017). We carried out several sensitivity analyses, the results of which were consistent with the findings of the primary analysis. In conclusion, our results suggest that, with the exception of regimens including zidovudine, accompanying antiretroviral drugs have little effect on the virological response to pegylated interferon plus ribavirin in HIV/HCV-co-infected patients.5.068 JCR (2011) Q1, 7/70 Infectious diseases, 18/114 Microbiology, 20/261 Pharmacology & pharmac
