Drug- Resistance- Associated Mutations and HIV Sub-Type Determination in Drug-Naïve and HIV-Positive Patients under Treatment with Antiretroviral Drugs
Abstract Background and Objective: Resistance to antiretroviral agents is a significant concern in clinical management of HIV-infected individuals. Resistance is the result of mutations that develops in the viral protein targeted by antiretroviral agents. Material and Methods: In this cross-sectional study, the blood samples of 40 HIV-positive patients were collected. Twenty of them were d...
متن کاملThe cost of antiretroviral drug resistance in HIV-positive patients.
INTRODUCTION Antiretroviral (ARV) drug resistance limits treatment choices, often necessitating the selection of drugs with less desirable pill burdens, toxicity profiles, drug interactions and dosing schedules, and may increase cost. We examine the impact of resistance on the cost of HIV care. METHODS All adult HIV-positive individuals newly referred for HIV care from 1 January 2007 to 1 Jan...
متن کاملEmergence of HIV-1 drug resistance during antiretroviral treatment.
Treating HIV-infected patients with a combination of several antiretroviral drugs usually contributes to a substantial decline in viral load and an increase in CD4(+) T cells. However, continuing viral replication in the presence of drug therapy can lead to the emergence of drug-resistant virus variants, which subsequently results in incomplete viral suppression and a greater risk of disease pr...
متن کاملCurrent Perspectives on HIV-1 Antiretroviral Drug Resistance
Current advancements in antiretroviral therapy (ART) have turned HIV-1 infection into a chronic and manageable disease. However, treatment is only effective until HIV-1 develops resistance against the administered drugs. The most recent antiretroviral drugs have become superior at delaying the evolution of acquired drug resistance. In this review, the viral fitness and its correlation to HIV-1 ...
متن کاملAntiretroviral drug resistance in HIV-infected patients in Colombia.
BACKGROUND Systematically obtained data on antiretroviral (ARV) resistance in Colombia are lacking. Local estimates of resistance are needed to guide testing, therapy, and policy. METHODS A cross-sectional study was performed in ARV-naïve individuals and in patients with first ARV failure. Genotypic resistance testing was performed using Viro-seq. Predicted success to first- and second-line r...
