Result: Thymidine analogues mutations (TAMs), selected mostly by ZDV and d4T, were prevalent (6/9; 66.66%), with type II TAMs being more frequently detected (4/9; 44.44%): K70R and K219Q (each in three cases), D67N and T215F (each in two cases).

Abstract: The concordance rates between the RFMP and direct sequencing assays for the examined codons were 97% (K65R), 97% (T69Ins/D), 97% (L74VI), 97% (K103N), 96% (V106AM), 97% (Q151M), 97% (Y181C), 97% (M184VI) and 94% (T215YF) in the reverse transcriptase coding region, and 100% (D30N), 100% (M46I), 100% (G48V), 100% (I50V), 100% (I54LS), 99% (V82A), 99% (I84V) and 100% (L90M) in th
Transmission patterns of HIV-subtypes A/AE versus B: inferring risk-behavior trends and treatment-efficacy limitations from viral genotypic data obtained prior to and during antiretroviral therapy.
Result: The latter differed significantly in the frequencies of the major resistance RT mutations T215FY and K219QE (NRTI) and of several secondary/accessory mutations, including: the protease mutations I13V, M36I, I62V, L63P, A71V, V77I, L89M and I93L (Table 6) and the RT mutations A98S, K101N, K103R and V179I (Table 5).

Result: M184V and T215Y/F were observed in plasma only in six and three patients, respectively, while M41L and K65R were observed in one patient each in provirus only.
Result: As expected, among the NRTI and NNRTI mutations, M184I/V (71.9%), T215Y/F (34.4%), K103N (34.3%), and Y181C (28.1%) were the most prevalent in any of the compartments.

HIV-1 drug resistance and associated factors among adults failing first-line highly active antiretroviral therapy in Ho Chi Minh City, Vietnam.
Abstract: Among 87 participating individuals with VL >=1,000 copies/mL, 11 people still harbored a wild-type strain, while 76 participants harbored a HIV-1 drug-resistant strain (2 of which were against protease inhibitors); common DRMs were M184I/V (74%), Y181I/C/V (39%), G190A/S (32%), T215Y/F (32%), and K103N (31%).
Antiviral resistance and correlates of virologic failure in the first cohort of HIV-infected children gaining access to structured antiretroviral therapy in Lima, Peru: a cross-sectional analysis.
Method: The OLA was conducted according to the NIH protocol for mutations at HIV-1B protease positions D30N, I50V, V82A, V82S, V82T, I84V, N88D, and L90M as well as reverse transcriptase positions K103N, Y181C, K65R, T215F, T215Y, M184V, and Q151M.
Result: The M184V reverse transcriptase mutation was detected in 80% of the seque
Connection subdomain mutations in HIV-1 subtype-C treatment-experienced patients enhance NRTI and NNRTI drug resistance.
Method: Vectors pHL[B-TAMs] and pHL[C-TAMs] were created by introducing NRTI resistance mutations D67N, K70R, T215Y/F, and K219Q into pHL[B-WT] and pHL[C-WT], respectively.
Result: Inherent levels of AZT resistance were first tested for wild-type subtype C in the absence (C-WT) or presence (C-TAMs) of TAMs (D67N, K70R, T215F/Y and K219Q).
Result: Slight increases in the AZT EC50 were observed between subtype B (18x) and C (28x) in the presence of TAMs, however this is likely due to the fact that the subtype B TAMs combination contained mutation T215Y instead of T215F.

Tenofovir-based regimens associated with less drug resistance in HIV-1-infected Nigerians failing first-line antiretroviral therapy.
Method: Thymidine analog mutations (TAMs) included M41L, D67N, K70R, L210W, T215F/Y, K219E/Q) that were further designated as TAM 1 (M41-L210-T215Y) or TAM 2 (D67-K70-T215F-K219).

Abstract: The prevalence of drug resistance was 13.8% (8/58) with detection of nucleoside reverse transcriptase inhibitor (NRTI) mutations, T215F (n=5), K219Q (n=3), M184V (n=1), and nonnucleoside RTI mutation, K103N (n=1).

Result: Mutations M41L (3.7%), T215Y/F/S/D/C/E (4.0%), K103N/S (4.7%) and L90M were most prevalent.
Discussion: The distribution of mutations is very similar to that reported in the European surveillance study SPREAD, with a predominance of the thymidine analog mutations, M41L and T215R/F, and L90M in the protease coding region.
