Analysis on Results of Genotypic Viral Resistance Test in 45 Children with Acquired Immunodeficiency Syndrome / 实用儿科临床杂志

ABSTRACT

Objective To observe the results of 45 cases with acquired immunodeficiency syndrome(AIDS) genotypic viral resistance test(GT) assay.Method The technitues provided by AB Applied Biosystem was used to check the mutations in the reverse transcriptase associated with significant viral resistance.Results Fourteen cases out of 40(35%)cases which failed from first line regimen showed resistance to both zedovudine(ZDV) and lamivudine(LMV),and 26 cases out of 40(65%) cases showed resistance to ZDV or lamivudine used in the first line.For no-nucleoside reverse transcriptase in habitor(NNRTIs),11 cases out of 40(27%) cases had resistance to nevirapine(NVP),29 cases out of 40(63%) cases showed resistance to both NVP and efairavir(EFV).Two cases out of 5 which failed from second line regimen showed that one drug from both first and second line had no resistance,so it still could be used in the new regimen.Conclusion GT assay is very useful for choosing a best and personalized regimen for AIDS patients.
