HIV-1 subtype diversity, drug resistance, and genetic transmission networks in men who have sex with men with virologic failure in antiretroviral therapy in Sichuan, China, 2011 to 2017.
Result: M184V/I (236/372, 63.44%), K65KR/R (78/372, 20.97%), D67DN/N (77/372, 20.70%), and K70E/R/KR (72/372, 19.35%) were most common NRTI-related mutations.
Switching to bictegravir/emtricitabine/tenofovir alafenamide maintained HIV-1 RNA suppression in participants with archived antiretroviral resistance including M184V/I.

Method: Primary NRTI-R substitutions were M41L, K65R/E/N, D67N, T69 insertions, K70E/R, L74V/I, Y115F, Q151M, M184V/I, L210W, T215Y/F and K219E/Q/N/R in RT.

Abstract: Tenofovir-resistance mutations K65R and K70G/E or >=3 thymidine analogue resistance mutations including M41L and L210W were found in 18/36 (50%) subjects on a tenofovir-containing regimen at failure.
A viral genome wide association study and genotypic resistance testing in patients failing first line antiretroviral therapy in the first large countrywide Ethiopian HIV cohort.
Trends in the Molecular Epidemiology and Genetic Mechanisms of Transmitted Human Immunodeficiency Virus Type 1 Drug Resistance in a Large US Clinic Population.
Abstract: The thymidine analogue mutations, M184V/I and the tenofovir-associated DRMs K65R and K70E/Q/G/N/T accounted for 82.9%, 7.3%, and 1.4% of NRTI-associated TDR, respectively.
Result: The TDF-associated SDRM K70E did not occur.
Research on the treatment effects and drug resistances of long-term second-line antiretroviral therapy among HIV-infected patients from Henan Province in China.
Discussion: TDF was used in the second-line program; the mutations associated with resistance to TDF were K65R, TAM (M41 L, K70R, L210 W, T215F), D67N, K70E, and Y115F.
Discussion: The K70E and Y115F mutations cause low-level resistance to TDF as well.

Introduction: As expected, patients failing AZT-based therapy did not develop mutations K65R, K70E, L74V, or Y115F, and only rarely were DRMs from the Q151M complex seen.
Acquisition of tenofovir-susceptible, emtricitabine-resistant HIV despite high adherence to daily pre-exposure prophylaxis: a case report.
Result: SGS was consistent with the standard genotype in detecting RT mutations: specifically L74V, L100I, M184V, and K103N were detected, but K65R and K70E were not.

Result: The NRTI TDRM identified at low frequency by NGS (<10% of the viral population), were D67N, K65R, and K70E, as well as F77L, which was the most frequent (8 patient samples) low-abundance (1.5-5%) NRTI TDRM identified.
