BACKGROUND: The therapeutic effect of antiretroviral therapy (ART) is adversely influenced by antiretroviral drug resistance, mainly due to mutations (DRMs) in the human immunodeficiency virus (HIV) genome. These mutations are commonly associated with HIV protease and reverse-transcriptase genes. We sought to determine the frequency of DRMs in a population of ART-experienced patients in the South of Iran. METHOD: A total of 44 HIV-1-positive participants under ART were selected from April 2016 to March 2017. Their DRMs, antiretroviral resistance status, and viral subtypes were determined. RESULTS: At least one DRM was detected in 61.4% of the participants. The highest frequency was related to nucleotide reverse-transcriptase inhibitor (NRTI) mutations (45.45%). In contrast, major protease inhibitor (PI) mutations had the lowest frequency (6.81%). M184V (40.9%) and K103N (25%), respectively related to NRTI and nonnucleoside reverse-transcriptase inhibitor (NNRTI), were the mutations with the highest frequencies. Susceptibility to PI drugs was higher compared to NRTIs and NNRTIs, which was consistent with the results of genotypic DRMs. CONCLUSION: The highest frequency of antiretroviral DRMs was related to NRTIs and NNRTIs. In contrast, PI resistance mutations had the lowest frequency. Laboratory-guided ART to avoid the expansion of mutants as well as investigating DRMs in other viral regions, such as integrase, are recommended.
