Detection of Gag C-terminal mutations among HIV-1 non-B subtypes in a subset of Cameroonian patients.

PMID: 35082353 2022 Scientific reports

Introduction: Following the Stanford algorithm (mutation list), minor resistance mutations (L10F, V11I, K20TV, L23I, L33F, K43T, F53L, Q58E, A71IL, G73STCA, T74P, N83D, and L89V) are assumed to have ancillary roles such as compensation for lower efficiency of proteolysis caused by major mutations; major resistance mutations (V32I, M46IL, I47VA, G48VM,

Prevalence and factors associated with HIV-1 drug resistance mutations in treatment-experienced patients in Nairobi, Kenya: A cross-sectional study.

PMID: 34622871 2021 Medicine

Result: This study found no atazanavir resistance mutations (I50L, I84 V, or N88S).

Temporal Trends in HIV-1 Mutations Used for the Surveillance of Transmitted Drug Resistance.

PMID: 34064774 2021 Viruses

Abstract: With the notable exceptions of I47A and I50L, most PI-SDRMs decreased in prevalence.

Result: Two SDRMS increased in prevalence among PI-experienced persons including V47A and I50L while 34 decreased in prevalence.

Discussion: The two SDRMs that increased in prevalence, I50L and V47A, are associated with reduced susceptibility to atazanavir and lopinavir, respectively.

Non-active site mutants of HIV-1 protease influence resistance and sensitisation towards protease inhibitors.

Abstract: In this study, mutations N88S and L76V, along with three other resistance-associated mutations, M46I, I50L, and I84V, are analysed by means of molecular dynamics simulations to investigate their role in complexes of the protease with different inhibitors and in different background sequence contexts.

Abstract: RESULTS: Using these simulations for alchemical calculations to estimate the effects of mutations M46I, I50L, I84V, N88S, and L76V on binding free energies shows they are in general in line with the mutations' effect on [Formula: see text] values.

Result: The most common major PI RAMs observed were M46I and V82A (n = 12; 12%); I54V (n = 10; 10%); I84V and L76V (n = 7; 7%); I47A/V (n = 3; 3%); I50L/V (n = 2; 2%); and V32I (n = 2; 2%) (Table 1).

Table: I50L/V

Discussion: The group receiving AZT plus 3TC or ABC plus 3TC showed the highest rate of PIs such as I54V, I84V, L76V, I47A/V, I50L/V, and V32I.

High Levels of HIV-1 Drug Resistance in Children Who Acquired HIV Infection Through Mother to Child Transmission in the Era of Option B+, Haiti, 2013 to 2014.

PMID: 30640198 2019 The Pediatric infectious disease journal

Result: One child had a major M46I PI mutation, which causes low level of resistance to all PIs except darunavir and tipranavir, and another had the I50L major PI mutation, which causes high level resistance to atazanavir (Table 1).
