Current HIV Research - Volume 16, Issue 2, 2018

The advent of next-generation sequencing has enabled greater resolution of viral diversity and improved feasibility of full viral genome sequencing allowing routine HIV-1 full genome sequencing in both research and diagnostic settings. Regardless of the sequencing platform selected, successful PCR amplification of the HIV-1 genome is essential for sequencing template preparation. As such, full HIV-1 genome amplification is a cr Read More

Background: Lopinavir and Ritonavir (LPV/r) treatment is widely used to prevent HIV mother-to-child transmission. Nevertheless, studies related to the impact of these compounds on patients, in particular in the foetus and newborns, are strictly required due to the controversial findings reported in the literature concerning possible neurologic side effects following the administration of these drugs. Objectives: In our study, we eval Read More

Objectives: Genotypic Tropism Testing (GTT) tools are generally developed based on HIV-1 subtype B (HIV-1B) and used for HIV-1C as well but with a large discordance of prediction between different methods. We used an established phenotypic assay for comparison with GTT methods and for the determination of in vitro maraviroc sensitivity of pure R5-tropic and dual-tropic HIV-1C. Methods: Plasma was obtained from 58 HIV-1C i Read More

Introduction: A possible strategy to combat mutant strains is to have a thorough structural evaluation before and after mutations to identify the diversity in the non-nucleoside inhibitor binding pocket and their effects on enzyme-ligand interactions to generate novel NNRTI's accordingly. Objective: The primary objective of this study was to find effects of multiple point mutations on NNRTI binding pocket. This study include Read More

Background: Human immunodeficiency virus-1 (HIV-1) mutates rapidly to escape host immune pressure. This results in the generation of positively selected mutations (PSM) throughout the viral genome. Escape mutations in Nef, one of the accessory proteins of HIV-1, which plays an important role in viral pathogenicity have previously been identified in several large cohort studies, but the evolution of PSMs overtime in various H Read More

Background: The role and mechanism of drug use or abuse in Antiretroviral Therapy (ART)-treated HIV disease are not completely known. Methods: To investigate the impact of drug use on HIV pathogenesis without confounding by HIV replication and ART adherence, we first analyzed the data from our clinical database in 103 HIV+ subjects with viral-suppressed ART treatment by a multiple regression test. Results: We found tha Read More

Background: Instrumental variable (IV) analyses are a common causal inference technique used in the absence of randomized data. Combination Antiretroviral Therapy (cART) was first introduced in 1996 and calendar periods have been used as a proxy for cART use. However, cART use misclassification can bias IV analyses. Objective: We aim to highlight the differences in the effects of antiretroviral therapy on clinical out Read More

Background and Objectives: Human Immunodeficiency Virus (HIV) is still a major health issue in Indonesia. In recent years, the appearance of drug resistance-associated mutations has reduced the effectiveness of Antiretroviral Therapy (ART). We conducted genotypic studies, including the detection of drug resistance-associated mutations (from first-line regimen drugs), on HIV-1 genes derived from infected individuals in M Read More

Background: Vitamin D is an immunomodulator, and its deficiency is associated with Tuberculosis (TB) infection. Bronchoalveolar lavage fluid (BALF) is a rich milieu of macrophages that form the first line of defense against invading TB bacilli. As there is an increased prevalence of vitamin D deficiency in TB and human immunodeficiency virus-1 (HIV-1) subjects, we intend exploring the possibility of a localized deficiency of vit Read More

Background: HIV infection is prevalent among men who have sex with men (MSM), and sexual roles may be important factors related to it. This study aims to describe the sexual roles, risky sexual behaviors and HIV prevalence among MSM, and to determine associated factors for HIV prevalence. Methods: A convenient sampling method was used to recruit participants in a non-government organization in Changsha, Ch Read More
