Abstract

This descriptive, retrospective study was design to evaluate the prevalence and characteristic of HIV protease mutation at L76V-Patients who had virological failure during LPV/r and good adherence. There were patients who had HIV protease mutation L76V (L76V+ group) and patients who did not had HIV protease mutation L76V (L76V- group). This study was collected at virological failure during LPV/r. Genotypic method was done. Risk factor and datas were collected after initial LPV/r therapy 3-6 months from medical record, until 1 Jan 2007 to 31 Dec 2010. Patients were under 18 years old. There were 16 patients who were included in this study.There were 3 patients(18.75) who were in L76V+ group and 13 patients (81.25%) who were in L76V- group. The prevalence of protease mutation L76V-patients who received LPV/r, had virological failure and good adherence was 18.75. Age, BMI and Plasma viral load were not different between 2 groups. Patients in L76V+ group received double boosted PI on virological failure during LPV/r more than L76V- group. Conclusion The prevalence of protease mutation L76Vpatients who received LPV/r, had virological failure and good adherence was 18.75. Third-line options in Antiretroviral drug should be carefully considered.
