摘要: Limited access to HIV drug resistance testing in low- and middle-income countries impedes clinical decision-making at the individual patient level. An efficient protocol address this issue must be established minimize negative therapeutic outcomes for HIV-1-infected individuals such settings. This is an observational study ascertain potential of newer genomic sequencing platforms, as Illumina MiSeq instrument, provide accurate genotypes hundreds samples simultaneously. Plasma were collected from Canadian patients during routine (n = 759) a Ugandan cohort 349). Amplicons spanning reverse transcriptase codons 90 234 sequenced with both conventional Sanger methods. Sequences evaluated nucleotide concordance between methods, using coverage mixture parameters quality control. Consensus sequences also analyzed disparities identification mutations. was successful 881 (80%) 892 (81%), respectively, 832 having results Most failures viral loads <3.0 log10 RNA copies/ml. Overall, 99.3% methods observed. achieved 97.4% sensitivity specificity detecting mutations identified by sequencing. Findings suggest that platform can yield high-quality data high-multiplex "wide" approach. strategy used multiple subtypes, demonstrating widespread annual population surveillance resource-limited
