Prevalence and persistence of transmitted drug resistance mutations in the German HIV-1 Seroconverter Study Cohort.

PMID: 30650082 2019 PloS one

Result: For a number of TDRMs, no loss could be observed during the observation period (S1 Table) and, according to their maximal duration of observation, the following TDRMs seem to survive for lengthy periods in the absence of ART: the NRTI resistance mutations D67N (5.9 years), K70R (6.9 years), F77L (10.2 years), T215E (5.9 years) and K219Q (5.9 years), the NNRTI resistance mutations A98G (6.5 years) and Y188L (5.9 years) as well as the PI mutations I54L (5.9 years) and L90M (8.4 years) (S1 Table).

Result: The presence of three or more TDRMs was mainly due to the accum

Persistence of Human Immunodeficiency Virus-1 Drug Resistance Mutations in Proviral Deoxyribonucleic Acid After Virologic Failure of Efavirenz-Containing Antiretroviral Regimens.

Method: Nucleoside reverse-transcriptase inhibitor DRMs included M41I/L, D67N/E, K70R, M184V, T215Y/F/C/S, K219Q/E; NNRTI DRM included K103N, Y181C, G190A/S/R, L100I, K101E, V106I/M, Y188H/C/L, M230I/L.

HIV-1 drug resistance testing is essential for heavily-treated patients switching from first- to second-line regimens in resource-limited settings: evidence from routine clinical practice in Cameroon.

PMID: 30871487 2019 BMC infectious diseases

Abstract: Thymidine-analogue mutations (TAMs)-1 [T215FY (46.53%), M41 L (22.77%), L210 W (8.91%)], with cross-resistance to AZT and TDF, were higher compared to TAMs-2 [D67N (21.78%), K70R (19.80%), K219QE (18.81%)].

Result: Of note, TAMs-1 were predominant (T215F/Y: 46.5%; M41 L: 22.8%; L210 W: 8.9%) and associated with higher levels of resistance to both AZT and TDF; as compared to TAMs-2 that had relatively lower prevalence (D67N: 21.8%; K70R: 19.8%; K219Q/E: 18.8%) and were associated preferentially with AZT/D4T-resistance.

Detection of human immunodeficiency virus Type 1 phylogenetic clusters with multidrug resistance mutations among 2011 to 2017 blood donors from the highly endemic Northern Brazilian Amazon.

PMID: 31119759 2019 Transfusion

Abstract: This cluster was characterized by NRTI (D67N, T69D, T215S/F/L, K219Q) and NNRTI (K101H, K103 N, G190A) mutations.

Result: Eleven (25%, 11/44) of the RTRM were thymidine analogue mutations (T215FY [2.5%, 6/239], K70R [1.7%, 4/239] and 0.8% (2/239) each of D67N, L210W, M41L, and K219Q/E (Fig 2).

Abstract: The most prevalent_Nucleoside_Reverse Transcriptase Inhibitor (NRTI) mutations were_M184V/I_(67.3%),_K219/Q/E_(22.6%) and_K65R_(21.1%).

Impact of the M184V/I Mutation on the Efficacy of Abacavir/Lamivudine/Dolutegravir Therapy in HIV Treatment-Experienced Patients.

PMID: 31660328 2019 Open forum infectious diseases

Method: Information on thymidine analogue mutations (TAMs; M41L, D67N, K70R, L210W, T215Y/F, and K219Q/E) before the switch to ABC/3TC/DTG also was obtained.

Result: Among the 21 patients who experienced VF, 2 had 3 archived TAMs (D67N, K70R, and K219Q/E and M41L, K70R, and K219Q/E), including the M184V/I mutation.

Result: One patient had 2 TAMs (D67N and K219Q/E) without an archived M184V/I

Analysis of HIV-1 diversity, primary drug resistance and transmission networks in Croatia.

PMID: 31754119 2019 Scientific reports

Result: Some of these sequences carrying SDRMs: T69D, G190E, K219Q and K219R + M41L belonged to large TCs (Table 3), others were not part of TCs, such as SDRMs K103N, G140A, G190A and M41L + T215D, while the sequence with SDRMs T215D + L210W formed a transmission pair with a Croatian sequence from the previous dataset (2006-2008) that carried the same resistance pattern.

Discussion: For mutations M46I, T69D, G190E, K219Q and
