Human Immunodeficiency Virus-1 Viral Load Is Elevated in Individuals With Reverse-Transcriptase Mutation M184V/I During Virological Failure of First-Line Antiretroviral Therapy and Is Associated With Compensatory Mutation L74I.

PMID: 31774913 2020 The Journal of infectious diseases

Method: Because some individuals may have been exposed to thymidine analogs before TDF-containing regimens, we excluded individuals with sequences containing TAMs:M41L, D67N, K70R, L210W, T215Y/F, and K219Q/E.

Trend of HIV-1 drug resistance in China: A systematic review and meta-analysis of data accumulated over 17 years (2001-2017).

PMID: 31922125 2020 EClinicalMedicine

Result: In NRTI mutations, T215I/Y/S/N/F/E had the highest percentage (31.2%) in subtype B, whereas M184I/V had the most predominant percentage (43.8-73.3%) in CRF01_AE and other subtypes (Table 2 and Appendix 20).

Result: The top NRTI mutations identified in ART-naive and ART-treated individuals were M184V/I (16.3% and 41.8%) and T215I/Y/S/D/F (20.9% and 9.5%), and the top NNRTI mutations were K103N/S (18.7% and 40.5%), Y181C/I (14.0% and 22.2%), and G190A/S (9.5% and 22.2%, respectively).

High resistance to reverse transcriptase inhibitors among persons infected with human immunodeficiency virus type 1 subtype circulating recombinant form 02_AG in Ghana and on antiretroviral therapy.

PMID: 32049783 2020 Medicine

Abstract: Major nucleoside reverse transcriptase inhibitor (NRTI) resista

Discussion: T215Y/F and K219E are major TAMs which give rise to high-level resistance to Zidovudine and Stavudine, especially when the mutations occur in concert with accessory TAMs like M41L, D67N, and K70R.

Discussion: Other mutations detected in this study, which have been shown to confer resistance to NRTIs, were M184I, T69N, L74I, M41L, K70R/E, T215Y/F, and K219E.

Result: RAMs I54AVPR, L90MPR, M41LRT, D67NPR, and T215FPR were significantly more frequent in subtype G isolates.

PMID: 32986709 2020 PloS one

Result: Identified TAMs were T215YF (n = 9), K219QE (n = 7), K70R (n = 7), D67N (n = 6), M41L (n = 4), and L210W (n = 3) (Table 3).

Nucleocapsid Protein Precursors NCp9 and NCp15 Suppress ATP-Mediated Rescue of AZT-Terminated Primers by HIV-1 Reverse Transcriptase.

PMID: 32747359 2020 Antimicrobial agents and chemotherapy

Abstract: Clinically relevant combinations of TAMs, such as M41L/T215Y or D67N/K70R/T215F/K219Q, enhance the ATP-mediated excision of AZT monophosphate (AZTMP) from the 3' end of the primer, allowing DNA synthesis to continue.

Abstract: In HIV-1, development of resistance to AZT (3'-azido-3'-deoxythymidine) is mediated by the acquisition of thymidine analogue resistance mutations (TAMs) (i.e., M41L, D67N, K70R, L210W, T215F/Y, and K219E/Q) in the viral reverse transcriptase (RT).
