Characterization of two HIV-1 infectors during initial antiretroviral treatment, and the emergence of phenotypic resistance in reverse transcriptase-associated mutation patterns.
Discussion: It is reported that a differential genetic barrier was found for V106M, V108I, P225H in different HIV-1 subtypes for NNRTI resistance-related substitutions.
Drug resistance in children at virological failure in a rural KwaZulu-Natal, South Africa, cohort.
Result: V108I accounted for 1.9%, and reduced NVP and EFV susceptibility.
Result: The mutations of both K103N and V108I caused high resistance to EFV and NVP.
Table: V108I
Discussion: When K103N and V108I mutations happened together, they caused high resistance to EFV and NVP.

Result: The next most common NNRTI-resistance mutations in subtype AFSU viruses were K103N (25 patients), Y181C (13 patients), G190A (8 patients), A98G (4 patients), V108I (3 patients), and Y188L (2 patients).
Use of dolutegravir in two INI-experienced patients with multiclass resistance resulted in excellent virological and immunological responses.

HIV type 1 drug resistance patterns among patients failing first and second line antiretroviral therapy in Nairobi, Kenya.
Result: However four patients had diverse drug mutations combinations of K103N and V108IV (n = 1); Y184V, G190A and T215Y (n = 1); K103N, M184V and T215Y (n = 1); and A98G, Y181C (n = 1) mutations.
Abstract: In patients with ETR failure, cross-resistance to RPV was seen in 27.6%, mainly as result of Y181C (81.3%), V179I (43.8%), V90I (31.3%) and V108I (18.8%).
Abstract: Mutations L100I and V108I were significantly more frequent in patients failing EFV than NVP (7.9 vs.
Greater suppression of nevirapine resistance with 21- vs 7-day antiretroviral regimens after intrapartum single-dose nevirapine for prevention of mother-to-child transmission of HIV.
Abstract: Four hundred twelve (98%) women had primary endpoint results available; of these, 5 (1.2%) had new NVP resistance detected by population genotype: 4 of 215 in the 7-day arms (1.9%; K103N in 4 women with Y181C, Y188C, or G190A in 3 of 4) and 1 of 197 (0.5%; V108I) in the 21-day arms (P = .37).
