Result: Twenty-five patients (36.7%) had secondary/compensatory mutations and the mutations patterns (
rtL91I,
rtQ149K,
rtQ215H/P/S and
rtN238D) were depicted in Table II.
Discussion: In the current study, among 68 patients, there were 25 (37%) secondary/compensatory resistance mutations (
rtL91I,
rtQ149K,
rtQ215H/P/S,
rtN238D) which are related to LdT, LAM, and ADV resistance.
