We especially thank Katarina Gyllensten and Lars Navér for expert advice on possible treatment modifications following resistance results, and particularly all study participants. This study
was supported by Sida/SAREC in a bilateral collaboration with the National Autonomous University of Honduras. “
“Chemokine (C-C motif) receptor 5 (CCR5) inhibitors are a novel class of antiretroviral agents Roxadustat that are promising for treatment of patients who harbour the HIV-1 R5 strain. Data on coreceptor tropism in non-B HIV-1 subtypes are limited. We studied coreceptor tropism in HIV-1 circulating in Thailand, where CRF01_AE predominates, using a genotypic assay. We compiled V3 sequences of HIV-1 strains circulating in Thailand during 2010–2012. Coreceptor tropism was predicted based on V3 sequences using geno2pheno version 2.5 (http://coreceptor.bioinf.mpi-inf.mpg.de). One hundred and fifty-five HIV-1-infected patients were enrolled in this study. Ninety-nine patients (63.9%) were antiretroviral-naïve, and the remainder had virological failure. The median (interquartile range) CD4 cell count and HIV-1 RNA were 220 (74–379) cells/μL and 75 374 (14 127–226 686) Palbociclib mouse HIV-1 RNA copies/mL, respectively. Of the sequences obtained from these patients, 119
(76.8%) were CRF01_AE and 22 (14.2%) were subtype B. At a false positive rate of < 5%, 61 (39.4%) HIV-1-infected individuals were predicted to Bcl-w harbour the X4 phenotype. X4 viruses were detected more frequently in
the treatment-failure group compared with the treatment-naïve group (30.3 vs. 55.4%, respectively; P = 0.002). Those with CRF01_AE had a higher proportion of X4 viruses compared with non-AE subtypes (47.9 vs. 11.1%, respectively; P < 0.001). By multivariate logistic regression, CRF01_AE and treatment failure were independently associated with predicted X4 phenotype [odds ratio (OR) 7.93; 95% confidence interval (CI) 2.57–24.50; P < 0.001, and OR 3.10; 95% CI 1.50–6.42; P = 0.002, respectively]. CRF01_AE and treatment failure are associated with the predicted X4 phenotype. In regions where CRF01_AE predominates, use of CCR5 inhibitors must be considered with caution. The phenotypic assay and its correlation with genotypes should be further investigated in CRF01_AE. "
“The aim of the study was to investigate the incidence of AIDS-defining cancers (ADCs) and virus-related and non-virus-related non-AIDS-defining cancers (NADCs) in HIV-infected patients compared with the general population, and to assess the risk factors associated with these malignancies. We performed a retrospective cohort study for the period from 1999 to 2009 of HIV-infected patients residing in the Local Health Authority of Brescia (northern Italy).
