Early reduction of viral load by daily dosage of IFN could enhance viral clearance. However, the duration of daily dosage protocol and the likely side-effects have not been well studied. We compared the efficacy and safety of a 4- vs 12-week daily IFN dosage in patients with CHC. METHODS: Fifty-nine, histologically proven CHC patients having ALT levels >1.5 ×ULN were divided randomly into 2 groups, group I was given IFN 3 MIU daily for 4 weeks, followed by tiw up to 12 months and group was given IFN 3 MIU daily for 12 weeks, followed by tiw up to 12 months. Ribavirin was given in a dose of 800-1200 mg/d for 12 months. RESULTS: Fifty-two of the 59 patients (group group completed the study. The pretreatment vari- ables and the prevalence of HCV genotype 1 were compara- ble between the groups. Nine patients (29%) in group and 6 (25%) in group had stage 3, 4 fibrosis. At the end of 4, 12, 24 and 52 weeks, HCV RNA negativity was ob- served in 27%, 54%, 65% and 71% in group I and 38%, 54%, 71% and 75% in group respectively (P =ns). Four of the eight (50%) patients with genotype 1 and 30 (69.8%) of 43 patients with genotype non-1 responded to therapy (P =ns). Sustained viral response was achieved in 61% and 71% in groups respectively. None of the variables predicted non-response precisely. No serious adverse effects were observed and they were comparable between the two groups. CONCLUSION: Daily IFN dosage with ribavirin is safe and can achieve response in up to 65% patients. Since the effica- cy of a 4-week daily dosage of IFN is comparable to a 12- week schedule, we recommend the former regimen.展开更多

Quantitative analysis was done for SENV H DNA.RESULTS: Twenty-one (22%) of 95 patients were positive for SENV DNA. There was no difference in clinical and biochemical parameters between patients with HCV infection alone and coinfected patients. The sustained response rate for HCV clearance after combination therapy did not differ between patients with SENV (52%) and without SENV(50%, n.s.). SENV DNA was undetectable in 76% of the initially SENV positive patients at the end of follow-up. SENV H response to combination therapy was significantly correlated with SENV DNA level (P=-0.05).CONCLUSION: SENV infection had no influence on the HCV sustained response rate to the combination therapy.Response rate of SENV to the combination therapy depends on SENV DNA level.展开更多
