Downregulation of SERINC5 expression in buffy coats of HIV-1-infected patients with detectable or undetectable viral load.

Among the host restriction factors against HIV, SERINC5 has been described in vitro, but the mRNA level of SERINC5 in vivo has been little studied. We compare SERINC5 expression in subjects with HIV-1 (highly active antiretroviral treatment (HAART) and HAART-naïve) with and without suppression of viral load. A cross-sectional study was performed with 107 individuals distributed as follows: 24 with HAART-naïve and detectable viral load (> 50 copies/mL), 13 with HAART and detectable viral load (> 50 copies/mL), 50 with HAART and undetectable viral load (≤ 50 copies/mL), and 20 without HIV-1.

Genomic instability in people living with HIV.

The increased life expectancy of people living with HIV (PLWH) receiving antiretroviral treatment (ART) has transformed HIV infection into a chronic disease. However, patients may be at risk of accelerated aging and the accumulation of cellular damage, which may trigger the development of cancer. We evaluated genomic instability in HIV-positive individuals with different viral loads receiving antiretroviral treatment (ART) and in HIV ART-naïve individuals.

MicroRNA-296-5p is differentially expressed in individuals with and without HIV-1 infection.

MicroRNAs are considered as potential biomarkers, agents, or therapeutic targets; few studies have addressed the expression of miRNAs in treatment-naïve patients infected with HIV-1. The aim of this study was to assess plasma relative circulating miRNA expression profiles in treatment-naïve Mexican patients with HIV/AIDS and healthy individuals using a commercial array. A low CD4+ T cell count and high viral load were found in all patients.

Plasma microRNA expression levels in HIV-1-positive patients receiving antiretroviral therapy.

Unlabelled: MicroRNAs (miRNAs/miRs) may serve as therapeutic agents or targets in diseases in which the expression of proteins plays an important role. The aim of the present study was to compare the expression levels of specific miRNAs, as well as their correlation with markers of response to antiretroviral (ARV) therapy, in patients with human immunodeficiency virus type 1 (HIV-1) infection with and without resistance to highly active antiretroviral therapy (HAART).

Methods: miRNA assays were performed on plasma samples obtained from 20 HIV-1-positive patients.

Effectiveness and Risk Factors for Virological Outcome of Raltegravir-Based Therapy for Treatment-Experienced HIV-Infected Patients.

Objective: We evaluated the effectiveness of a raltegravir (RAL)-containing regimen plus an optimized background regimen in HIV-1 highly treatment-experienced patients.

Design: A retrospective cohort, multicentre study was conducted.

Methods: Adult (>16 years old) HIV treatment-experience patients starting therapy with a RAL-containing regimen were included.

Extended treatment with pegylated interferon alfa/ribavirin in patients with genotype 2/3 chronic hepatitis C who do not achieve a rapid virological response: final analysis of the randomised N-CORE trial.

Background And Aims: The combination of pegylated interferon alfa/ribavirin will likely remain the treatment of choice for HCV genotype 2/3 patients in financially constrained countries for the foreseeable future. Patients with poor on-treatment response may benefit from treatment extension. This study examined the effect of 48 versus 24 weeks of peginterferon alfa-2a/ribavirin on the sustained virological response (SVR) in patients with HCV genotype 2/3 who did not achieve rapid virological response (RVR).
