Abstract: Of the 35 patients with mutations at T2, 80% had M184V/I, 65.7% Y181C, and 48.6% (54.8% excluding those not on Tenofovir) had K65R mutations.
Abstract: The high rate of K65R and TAMs could compromise second line regimens including NRTIs.
Conclusion: The second-line regimens recommended were appropriate, however, the high rate of the K65R and TAMs is likely to compromise second-line drugs containing other NRTI backbone.
Result: Of the 35 patients with mutations at T2, 80% had M184V/I, 65.7% Y181C and 48.6% (54.8%, if those not on Tenofovir are excluded) had K65R mutations.
Result: The 22 cases experiencing virologic failure presented with the following DRMs: M46I, F53LY, I54LTV, G73ST, L76V, V82AT, I84V, I185V, N88D, and L90M for PIs; L100I, K103NS, V179F Y181C, G190AS, V106A, K103N, and P225H for NNRTIs; and
HIV-1 Drug Resistance Mutations: Potential Applications for Point-of-Care Genotypic Resistance Testing.
Result: About one-half of the viruses with K65R did not have M184V, making K65R the second largest contributor to the cumulative proportion of viruses with a major NRTI DRM.
Result: Fig 2 shows that in viruses from individuals in LMICs with intermediate or high-level NRTI resistance following VF on a first-line NRTI/NNRTI-containing regimen, the most common major DRMs were M184V (91.5%) and M184I (3.7%), K65R (9.8%), and the TAMs K70R (14.6%),

Abstract: K65R/N and Q151M complex existed in 23 and 4 patients, respectively.
HIV-1 virologic failure and acquired drug resistance among first-line antiretroviral experienced adults at a rural HIV clinic in coastal Kenya: a cross-sectional study.
Method: In this study, HIV-2 resistance mutations were identified using the list generated by the 'Collaborative HIV and Anti-HIV Drug Resistance Network', leading to the following mutations in reverse transcriptase - K65R, D67G/N, N69S/T, K70N/R, L74V, V111I, Y115F, M184I/V, Q151M, S215A/C/F/L/Y, K223R; and in protease - V47A, G48V, I50V, I54L/M,
Characteristics of HIV-1 natural drug resistance-associated mutations in former paid blood donors in Henan Province, China.
Discussion: Results from the HIV-1 drug resistance mutation research by the International AIDS Society-USA (updated in March 2013) have revealed that PI resistance mutation sites are L10I, K20M, V32I, M36I, M46I/L, I47V/A, I50V, Q58E, A71V, G73S, V82A/F/T, I84V, L89V,L90M; NRTIs resistance mutations are M41L, A62V, PMID: 24633208

Abstract: In multivariate regression models, K65R, Y115F and the presence of thymidine analogue-associated mutations were associated with increased susceptibility to etravirine in the cABC arm.
Result: However, in the case of etravirine, K65R, Y115F
Discussion: Although our results are based on a small number of observations (K65R was only observed in one individual) and interpreted cautiously, the associations with TAMs and K65R have been reported previously, but this is, to our knowledge, the first report of an effect of Y115F.
Discussion: However, we did find that the presence of TAMs, K65R and Y115F were independent predictors of increased etravirine susceptibility.
