Result: The most prevalent PI DRMs were M46I (3/120; 2.5%) and L10F (2/120; 1.7%) in Armenia and N88D (2/96; 2.1%) in Azerbaijan.
Discussion: The most frequent PI DRMs included M46I and L90M, which are associated with DR to nelfinavir, which was not considered for PDR estimation and has not been used since 2013; additionally, N88D and L10F only minimally reduce susceptibility to drugs.

Result: Additionally, the most common protease inhibitors associated mutation was Q58E (0.23%, 11/865), followed by M46I (4.05%, 5/865) and L33F (2.89%, 3/865)(as shown in Figure 2).
High Level of Pre-Treatment HIV-1 Drug Resistance and Its Association with HLA Class I-Mediated Restriction in the Pumwani Sex Worker Cohort.
Result: The HLA-DRM associations involving HLA alleles at >10% frequency in Kenya are A*68:02 with DRMs G190ES (p = 0.008), IN E138K (p = 0.042), C*17:01 with DRMs M46I (p = 0.018), and IN E138K (p = 0.021).
Discussion: The clinically significant mutations with the highest prevalence among the study participants were M184I (37%) and E138AK (15%) on RT, D30N (10%) and M46I (8%) on PR, and E138K (6%) on IN.
