Genetic profile and characteristics of HIV-1 drug resistance mutation in the Krasnodar region over the 2014 to 2019

Objective. Molecular genetic analysis of AIDS-1, having spread in the territory of Krasnodar region over the 2014 to 2019, including analysis of drug resistance mutationMaterials and methods. The study used the collection of samples, obtained from 478 HIV-infected people, living in the territory of Krasnodar region over the 2014 to 2019; out of them 155 received antiretroviral therapy (ART). Genotyping of the obtained samples was carried out with the further phylogenetic analysis, including detailed analysis of identified unique recombinant forms of HIV-1.Results. It is shown that HIV-1 sub-subtype A6 (80,5%) continues dominating in the territory of Krasnodar region, genetic variant B (9,2%) is the second most common one. Also 11 unique recombinant forms (URFs) were discovered, 10 out of which are the result of A6 and B genetic variants recombination. Drug resistance mutations were registered with 114 patients, received ART (73,6%); primary mutations — M184V and A62V. Provisional indicator of transmissible drug resistance in the population of naïve patients is 4,6% (15/323); primary mutations — K103N и G190S. Conclusion. The analysis of genetic profile and HIV-1 drug resistance mutation is carried out in the territory of Krasnodar region over the 2014 to 2019.
