Epidemiological Surveillance of HIV-1 Transmitted Drug Resistance in Spain in 2004-2012: Relevance of Transmission Clusters in the Propagation of Resistance Mutations.
Result: It is noteworthy that several major mutations associated to high level resistance to NRTIs (K65R, L74V, Y115F, M184V and T215Y), to NNRTIs (l100I, K101E, K103N/S, V106M, Y181C, Y188L and G190A) and to PIs (D30N, M46I/L, I54V/T, L76V, V82A, I84V, N88D
Identification of mechanistically distinct inhibitors of HIV-1 reverse transcriptase through fragment screening.
Abstract: Three compounds were found to inhibit RNA- and DNA-dependent DNA polymerase activity of HIV-1 RT in the micromolar range while retaining potency against RT variants carrying one of three major NNRTI resistance mutations: K103N, Y181C, or G190A.
The prevalence and determinants of drug-resistance-associated mutations in the HIV-1-infected MSM population of Henan Province in China.
Method: A NVP RAM was considered if at least one of the following genetic changes in reverse
Result: Of these, the most frequent mutations were K103N (n = 16, 24.2%, 95% CI 13.4-34.6) and Y181C (n = 15, 22.7%, 95% CI 12.6-32.8), and G190A (n = 10, 15.2%, 95% CI 6.5-23.8).
Result: The NNRTI RAM most frequently represented in this ARV class were K103N (n = 16, 21.6%, 95% CI 12.2-31.0) and Y181C (n = 15, 20.3%, 95% CI 11.1-29.4) and G190A (n = 10, 13.5%, 95% CI 5.7-21.3).
Discussion: The most frequent reverse transcriptase mutations were Y181C, K103N and G190A.
Frequency of transmitted drug resistance mutations among treatment-naive HIV-1-infected individuals at a tertiary care centre in South India.
Abstract: RESULTS: Prevalence of SDRMs in drug-naive and treatment-failing patients were linearly correlated, but some SDRMs were classified as outliers - above (PRO: D30N, N88D/S, L90 M, RT: G190A/S/E) or below (RT: M184I/V) expectations.
Result: For NNRTIs, Y181C/I/V was below the CI and G190A/E/S was above the CI in
Discussion: Our results are consistent with other studies: M184I/V has been shown to have low persistence after transmission to drug-naive patients; G190A has been shown to have high persistence.
Comparison of 454 Ultra-Deep Sequencing and Allele-Specific Real-Time PCR with Regard to the Detection of Emerging Drug-Resistant Minor HIV-1 Variants after Antiretroviral Prophylaxis for Vertical Transmission.
Result: Twenty-eight NVP-selected mutations (V90I, K101E, K103N/R, V106A/I/M, V108I, E138A/G/K/R, Y181C, Y188C, G190A or P225H) were detected in 19 samples at levels of 1.1% to 99.1%.
