Abstract: Approximately 6- to 11-fold decreases in susceptibility to 4'-Ed4T were observed for HIV-1 carrying NRTI-associated mutations (D67N, K70R, T215F, and K219Q) or the lamivudine (3TC)-resistant mutation M184V.
Drug-resistance mutations number and K70R or T215Y/F substitutions predict treatment resumption during guided treatment interruptions.
Abstract: Mutation T215F was preferentially associated with K70R (>71%), D67N (>73%) and K219Q/E/N (>76%), whereas T215Y was associated with M41L (>84%) and L210W (>58%).
Abstract: We showed that mutation T215Y is predominant over T215F (respectively 38.8 vs.

Abstract: The most frequent mutations were M41L, M184V, and T215FY in RT and L62PI, L10FIRV and M36I in PT.

Abstract: Although K70R has been described as the first mutation to appear in patients receiving ZDV monotherapy, the T215Y/F mutation appeared first in patients receiving dual-nucleoside combination therapy.

Abstract: Genes encoding AZT-resistant RTs with single or combined mutations D67N, K70R, T215F, and K219Q, and RTs derived from drug-resistant HIV-1 strains were designed and expressed in a variety of eukaryotic cells.
Transmitted human immunodeficiency virus type 1 carrying the D67N or K219Q/E mutation evolves rapidly to zidovudine resistance in vitro and shows a high replicative fitness in the presence of zidovudine.
Abstract: Through the analysis of resistance mutations in 1082 newly diagnosed antiretroviral-naive persons from the United States, we found that 35 of 48 (72.9%) persons infected with HIV-1 containing thymidine analog mutations (TAMs) had viruses that lacked a primary mutation (T215Y/F, K70R, or Q151M).
Genotypic determinants of the virological response to tenofovir disoproxil fumarate in nucleoside reverse transcriptase inhibitor-experienced patients.
Abstract: RESULTS: The strongest association with decrease in viral load was observed with a set of seven mutations (TDF mutation score) that consisted of M41L, E44D, D67N, T69D/N/S, L74V, L210W and T215Y/F RT mutations.

Abstract: A comparable correlation was obtained when ZDV-R was analyzed only relative to the T215Y/F mutation.

Abstract: Based on univariate analysis, a high CD4(+) cell count before antiretroviral treatment, homosexual behavior as a risk factor for HIV infection, reduced drug exposure to nonnucleoside reverse transcriptase inhibitors, low replicative capacity of HIV isolates, and more frequent detection of HIV isolates with a non-B subtype, an R5 biological phenotype, and M184V and T215Y/F mutations were factors associated with a discordant response to HAART.
