Clinical impact of ultra deep versus Sanger sequencing detection of minority mutations on HIV-1 drug resistance genotype interpretation after virological failure
2014
Methods Fifty HIV-1 patients who experienced virological failure were included in this retrospective study. The HIV-1 UDS protocol was performed using the GS Junior (Roche 454 Life Sciences Branford, CT). This UDS protocol allowed the detection and quantification of minor and major HIV-1 protease and reverse transcriptase variants related to genotypes A, B, C, E, F and G. DeepChekHIV (ABL, SA and TherapyEdgeTM, USA) simplified drug resistance (DR) interpretation software was used to compare Sanger sequencing and UDS at two different thresholds (≥1% and ≥20%). DeepChek-HIV utilizes the ANRS, HIVdb and Rega algorithms.
