Concordance of genotypic resistance interpretation algorithms in HIV-1 infected patients: An exploratory analysis in Greece.

Purpose: Genotypic resistance-related mutations in HIV-1 disease are often difficult to interpret. Different algorithms have been developed to provide meaningful application into clinical context. We aimed to compare, for the first time in Greece, the results of genotypic resistance derived from three interpretation algorithms.

Transmitted drug resistance among HIV-1 drug-naïve patients in Greece.

Objectives: Despite the success of antiretroviral treatment (ART), the persisting transmitted drug resistance (TDR) and HIV genetic heterogeneity affect the efficacy of treatment. This study explored the prevalence of TDR among ART-naïve HIV patients in Greece during the period 2016-2019.

Methods: Genotypic resistance testing was available for 438 ART-naïve HIV patients.
