Limited data exist on HIV‐1 drug resistance patterns in South Africa following second‐line
protease‐inhibitor containing regimen failure. This study examined drug resistance patterns …

Limited data exist on human immunodeficiency virus type 1 (HIV-1) resistance in patients
who are not responding to protease inhibitor (PI)–based regimens in resource-limited …

Background We investigated the prevalence of wild-type virus (no major drug resistance)
and drug resistance mutations at second-line antiretroviral treatment (ART) failure in a large …

Objective: To assess the virological response, genotypic resistance profiles, and
antiretroviral plasma concentrations in HIV-2 antiretroviral-treated (antiretroviral therapy …

Abstract Development of drug resistance is considered a major cause for failure of
antiretroviral therapy in human immunodeficiency virus type 1 (HIV‐1)‐infected patients …

Rates of antiretroviral resistance in recently transmitted virus in Sydney, Australia fluctuated
over the past decade, influenced by treatment trends. Current rates of drug resistance are …

Background. Emergence of human immunodeficiency virus type 1 (HIV-1) drug resistance
may limit the benefits of antiretroviral therapy in resource-limited settings. The prevalence of …

We analyzed antiretroviral drug susceptibility in HIV-infected adults failing first-and second-
line antiretroviral treatment (ART) in Rakai, Uganda. Samples obtained from participants at …

Background. As antiretroviral therapy (ART) programs in sub-Saharan Africa mature,
increasing numbers of persons with human immunodeficiency virus (HIV) infection will …

Baseline HIV-1 resistance data are important for resistance monitoring purposes especially
in regions initiating large-scale antiretroviral treatment programs. We examined 40 protease …
