The total number of patients included in this study was 1375 and all of them were infected with HCV genotype 3. On the basis of drug combinations, all the patients were separated into two groups. The first group of patients was treated for 24 wk with SOF(Sovaldi? by Gilead Sciences) plus ribavirin(RBV) [Ribazol? by Getz Pharma Pakistan(PVT) Ltd], while the patients of the second group were treated with SOF + RBV + pegylatedinterferon(peg IFN) alfa-2 a(Ropegra by Roach) for 12 wk. HCV genotyping and viral load measurement were performed on fully automated Abbott Real-Time PCR system(Abbott m24 sp automated nucleic acid extraction system and Abbott m2000 rt amplification system; abbott Molecular, Des Plaines, IL, United States). For the assessment of sustained virological response(SVR), all HCV RNA negative patients were followed for 12weeks after the treatment completion. Any patient with less than 12 IU/m L viral load after 12 wk of treatment completion was considered as a sustained virological responder(SVR-12).RESULTS A total of 1375 patients chronically infected with HCV genotype 3 were treated with two drug combinations SOF + RBV and SOF + RBV + peg IFN alfa-2 a. On the basis of these drug combinations, patients were divided into two groups(first and second). Overall SVR-12 was excellent in both groups(99.17% and 97.91%). Older patients(> 40 years) of second group showed lower SVR-12(93.46%) compared to first group older patients(98.79%), while in the younger patients of both groups, the SVR-12 rate was almost the same(99.54% in first group and 99.05% in second group). No such difference regarding SVR-12 rate was seen in males and females of first group patients(99.68% and 98.88%, respectively), while in second group the males were found to be better responders compared to females(98.96% and 95%). The SVR-12 rate in previously treated patients of first group was better(99.34%) than second group(93.70%), while na?ve patients of second group were marginally better responders(99.25%) than first group(97.80%). Rapid viral response at week-4 was found to be a very effective predictor for assessing the SVR rate at this stage of therapy in both groups. Headache, anemia and fatigue were common side effects in both groups either treated with SOF + RBV or SOF + RBV + peg IFN alfa-2 a, while the overall percentage of the side effects was higher in second group.CONCLUSION The remarkable SVR response rate of HCV genotype 3 infected patients to SOF provided a new way to look forward to eliminate hepatitis C from our region.展开更多
