HIV Type 1 Integrase Natural Polymorphisms in Viral Variants Circulating in FSU Countries

Abstract

The results of the study suggest a very low risk of initiating INSTI-based therapy in patients with pre-existing polymorphic mutations in Russia and FSU countries. The therapy response in dominating HIV-1 genetic variants might be further studied in the future for a better understanding of their effect on INSTI susceptibility. The INSTI TDR is absent for the moment, but the risk may increase with expanded use of INSTIs, indicating the need for ongoing surveillance.
