“…Viral nucleotide sequences were subtyped using the NCBI Genotyping tool and Bayesian phylogenetic analysis. Predicted protein translations were searched for thirty mutations previously reported as associated with viral resistance against various nucleos(t)ide analogues including rtL80V/I, rtV84M, rtS85A, rtS135Y, rtI169T, rtV173L, rtL180M/C, rtA181T/V/S, rtT184G/A/S, rtA194T, rtS202I/G, rtM204V/I/S, rtV214A, rtQ215S, rtL229V, rtN236T, rtP237H, rtN238T/D and rtM250V/L [3,5,12]. Chi square and Student's t tests were used to analyze mutation distribution among nucleos(t)ide analogues-naïve and -treated patients.…”

“…Posteriormente, a mutação rtA181T/V/S também foi relacionada com redução da susceptibilidade viral a esse NA (223,227,228). Além dessas mutações, diversas mutações compensatórias em diferentes domínios da RT já foram identificadas em cepas com resistência à lamivudina: rtL80V/I, rtV173L, rtL180M/C (223, 228), rtA200V (229), rtV/F/L/M207I (230), rtQ215S (231,232), rtL217P e rtL229F (233).…”

“…Estas mutações isoladamente conferem redução mínima da susceptibilidade ao entecavir (223). Um estudo publicado recentemente associou a presença de duas novas mutações (rtS219A e rtY245H) à redução da susceptibilidade ao entecavir (227).…”

“…The primary mode of action of these agents is [19]. For the detection of drug resistance, a large variety of methods have been used [19,20]. The most common methods in use today are direct sequencing of PCR product after amplification of a portion of the polymerase gene and detection with the commercially available reverse-phase hybridization line probe assay, INNO-LiPA Ò DR (Innogenetics; Ghent, Belgium) [21].…”

“…Direct sequencing lacks sensitivity in detecting minor populations of emerging drug-resistant virus, but it has the advantage of detecting mutations which may not yet be correlated with drug resistance. The INNO-LiPA assay has proven to be more sensitive than direct sequencing for the detection of minor populations of virus with known drug resistance, but it cannot detect new mutations that may be associated with drug resistance [20]. The plethora of different methods for identifying changes associated with antiviral resistance reinforces the need for standardization [19].…”
