Zidovudine (AZT) monotherapy selects for the A360V mutation in the connection domain of HIV-1 reverse transcriptase.

PMID: 22363673 2012 PloS one

Introduction

Result: Of note, the A360V in the connection domain of HIV-1 RT was also significantly associated with AZT monotherapy and was more frequent than the M41L, D67N, L210W or K219E/Q mutations.

Result: To further confirm the role of A360V in AZT resistance, we generated 5 site-directed mutant viruses in pxxLAI that contained A360V in 2 different backgrounds of TAMs (TAM-1 and D67N/K70R).

Emergence of minor drug-resistant HIV-1 variants after triple antiretroviral prophylaxis for prevention of vertical HIV-1 transmission.

Result: We also checked population sequences for additional AZT/3TC/NVP-selected resistance mutations like M41L, D67N, K70R, L210W, T215Y/F and K219QE for AZT, K65R for 3TC and L100I, K101P, V106A/M, V108I, Y188C/L/H and G190A for NVP.

Low prevalence of transmitted drug resistance in patients newly diagnosed with HIV-1 infection in Sweden 2003-2010.

PMID: 22448246 2012 PloS one

Method: The following resistance mutations were scored: to nucleoside reverse transcriptase inhibitors (NRTIs): M41L, K65R, D67N/G/E, T69D/insertion, K70R/E, L74V/I, V75M/T/A/S, F77L, Y115F, F116Y, Q151M, M184V/I, L210W, T215Y/F/I/S/C/D/V/E, K219Q/EN/R; to non-nucleoside revers

Abstract: SDRMs were identified in 14/219 (6.4%) subjects; 8/14 were resistant to nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs; T69D, L74V, V75M, M184V/I and K219R), 5/14 to non-nucleoside reverse transcriptase inhibitors (NNRTIs; K103N, V106M, Y181C, Y188C and G190A), 1/14 to both NRTIs and NNRTIs (D67N and Y181C) and none to

Result: The most prevalent mutations in this dataset included: K103N (n = 30; 38.5%), M184V (n = 26; 33.3%), T215Y (n = 13; 16.7%), T215F (n = 8; 10.3%), M41L (n = 9; 11.5%), V106M (n = 8; 10.3%), D67N (n = 9; 11.5%), V108I (n = 8; 10.3%).

Impact of Novel Resistance Profiles in HIV-1 Reverse Transcriptase on Phenotypic Resistance to NVP.

PMID: 22536497 2012 AIDS research and treatment

Discussion: The group found H221Y was strongly associated with the use of NVP and showed positive interactions with Y181C and was also negatively associated with the use of ZDV and with TAMs (particularly TAMs-2, such as D67N, K70R, K219Q/E, and T215F) and was then associated with an increased susceptibility to ZDV.

Transmitted drug resistance and phylogenetic relationships among acute and early HIV-1-infected individuals in New York City.

PMID: 22592583 2012 Journal of acquired immune deficiency syndromes (1999)

4Method: ARV resistance was defined by mutations at the following positions: M41L, A62V, K65R, D67N, T69ins, K70R, L74VI, Y115F, Result: D67N(P=0.03), K70R(P=0.06), M184V(P=0.11), L210W(P=0.11), and K219Q(P=0.02) decreased during the study period.

Result: One clustered pair had M46L, another had T215D, and a third had K103N, D67N and K219Q.

K65R in subtype C HIV-1 isolates from patients failing on a first-line regimen including d4T or AZT: comparison of Sanger and UDP sequencing data.

PMID: 22615779 2012 PloS one

Discussion: The Sanger results of isolates from treated patients were as expected with a predominance of M184V, numerous TAMs of pathway1 (M41L, D67N, K70R, L210W, T215Y/F) and DRMs to NNRTIs (mainly K101E, K103N, V106M, Y181C, G190A).

Prevalence of HIV drug resistance mutation in the northern Indian population after failure of the first line antiretroviral therapy.

PMID: 22716105 2012 Current HIV research

Abstract: NRTI and NNRTI DRMs were each seen in 115/128 (89.8%) patients, with M184V, M41L, D67N and T215Y being the most frequent among NRTI associated mutations, and K103N, G190A, Y181C and A98G among NNRTI associated ones.

Abstract: The most prevalent RT mutations were T215F/V/Y (66.7%), D67G/N (55.6%), K219Q/E/R (44.4%), M184V/I (38.9%), K70R/E (27.8%) and M41L (27.8%), associated with nucleoside reverse transcriptase inhibitors (NRTI) resistance; and K103N (55.6%), G190A (33.3%), and K101P/E/H (27.8%) associated with non-nucleoside reverse transcriptase inhibitors (NNRTI) resistance.
