HIV Pretreatment Drug Resistance Trends in Mexico City, 2017-2020.

PMID: 34959542 2021 Pathogens (Basel, Switzerland)

Result: Other interesting clusters evidencing PDR transmission within the network included cluster PI-1, with 29 nodes, all men with PI resistance and median age 24 (22-28) enrolled across all years; cluster NRTI-1, with 23 nodes, 22 cisgender men and 1 cisgender woman, with median age 22 (10-27) and constant growth across all years; cluster complex-1, with 10 nodes, all men enrolled from 2018 to 2020 and median age 23 (20-30), 60% (6/10) with PI + NRTI + NNRTI resistance and 40% (4/10) with PI + NRTI resistance; and complex-2, with 7 nodes, all men with median age 26 (21-31) sharing PR M46I, L90M,

Transmitted drug resistance and transmission clusters among HIV-1 treatment-naive patients in Guangdong, China: a cross-sectional study.

PMID: 34488793 2021 Virology journal

Discussion: The most frequent NRTI-associated mutations in our study were M184V and L210W, while they are M41L and D67G in Southwest China and T215C/D in Iceland and the south-central United States.

Transmitted drug resistance to Tenofovir/Emtricitabine among persons with newly diagnosed HIV infection in Shenyang city, Northeast China from 2016 to 2018.

PMID: 34243716 2021 BMC infectious diseases

Discussion: It is no surprise that NNRTI-related mutations increased rapidly in China recently, and M184V/I and T215I/Y/S/D/F were the main NRTI DRMs in ART-naive and ART-treated individuals, respectively.

Temporal Trends in HIV-1 Mutations Used for the Surveillance of Transmitted Drug Resistance.

PMID: 34064774 2021 Viruses

Method: Thymidine-analog mutations were defined as the NRTI-SDRMs M41L, D67N/G/E, K70R, L210W, T215Y/F/S/C/D/E/I/V, and K219Q/E/N/R.

Result: Three mutations demonstrated a change in prevalence among RTI-naive persons: M41L, F77L, and T215D each decreased in prevalence.

Discussion: Conversely, four of the T215 revertant mutations, T215C/D/E/S had treatment/naive prevalence ratios of about 1.0 raising the question of whether these mutations will remain useful for the ongoing survei

Transmitted HIV-1 drug resistance in a large international cohort using next-generation sequencing: results from the Strategic Timing of Antiretroviral Treatment (START) study.

PMID: 33369017 2021 HIV medicine

Abstract: Using the 2% detection threshold, individual DRMs with the highest prevalence were: PI M46IL (5.5%), RT K103NS (3.5%), RT G190ASE (3.1%), T215ISCDVEN (2.5%), RT M41L (2.2%), RT K219QENR (1.7%) and PI D30N (1.6%).

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: 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).

Discussion: Similarly, another free NRTI drug AZT, which was often used in the first-line ART regimens, also faced an increased resistance by high percentage of mutation T215D/S/C among both ART-treated and ART-naive individuals.

Prevalence of acquired drug resistance mutations in antiretroviral- experiencing subjects from 2012 to 2017 in Hunan Province of central South China.

PMID: 32183889 2020 Virology journal

Result: The most common primary NRTI mutations detected included M184V (62.04%), K65R (20.24%), K70R (15.01%), T215D/S (9.41%), Y115F (7.22%) and M41L (6.35%).

The characteristics of pretreatment HIV-1 drug resistance in western Yunnan, China.

PMID: 32381145 2020 Epidemiology and infection

Result: Among the key DRMs for NRTIs, K65R (1.6%, 5/322) conferred high-level resistance, T69D (0.3%, 1/322) conferred intermediate resistance and M41L (0.6%, 2/322), D67N (0.6%, 2/322) and T215D (0.3%, 1/322) conferred low-level resistance.
