ABSTRACT
BACKGROUND: Sofosbuvir/Velpatasvir (Epclusa, ECS) is the first pan-genotype direct-acting antiviral agent (DAA) for hepatitis C virus (HCV) infection, and Danoprevir (DNV) is the first DAA developed by a Chinese local enterprise, which is suitable for combined use with other drugs to treat genotype 1b chronic hepatitis C. However, previous reports have never compared the real-world data of ECS and DNV. PATIENTS AND METHODS: 178 chronic hepatitis C patients were retrospectively recruited, and 94cases were accepted with Sofosbuvir/Velpatasvir ± Ribavirin (ECS group), and others (n = 84 treated with DNV combination therapy (DNV group). The HCV genotype, virological response, adverse effects and some laboratory biochemical indexes were contrasted between above two groups in the real world study. RESULTS: DNV group had significantly lower level of alpha-fetoprotein (AFP), lower rates of decompensated cirrhosis ( P < 0.05). ECS group possessed more 6a (31.91% vs.13.10%) while DNV group was provided with more 1b (48.81% vs. 22.34%) patients. Significantly poor liver function was detected in ECS group at 4-week treatment (ALT and AST) and 12-week follow-up (AST) (all P < 0.05). The SVR12 undetectable rates of both groups were 100%, and no serious event was observed during the treatment and follow-up in both groups. CONCLUSION: In this retrospective real-world study, the efficacy of DNV combined therapy is similar to Sofosbuvir/Velpatasvir ± Ribavirin for chronic HCV infection, and the safety is comparable. DNV based therapy is a promising regimen for chronic hepatitis C.

OBJECTIVE: To study the clinical characteristics of the patients with dengue fever (DF) seen from 2002 to 2006 in Guangzhou in order to prevent and treat dengue fever better. METHODS: Clinical data from 1342 inpatients with DF seen from 2002 to 2006 were retrospectively analyzed. The dengue virus was isolated by C6/36 cell culture and genotyped by reverse transcriptase-polymerase chain reaction and gene sequence analysis. RESULTS: The average age of the patients was 34.4 years, without sex difference in distribution. Most of the patients had obvious toxemic symptoms including fever (100 percent), headache (85.9 percent), myalgia (64.5 percent), bone soreness (46.6 percent) and skin rash (65.9 percent). Leukopenia, thrombocytopenia, elevated alanine aminotransferase, elevated aspartate aminotransferase and hypokalemia were found in 66.0 percent, 61.3 percent, 69.0 percent , 85.7 percent and 28.4 percent of patients, respectively. DF-IgM could be detected in 90 percent of patients. The virus was identified as dengue virus type-I. CONCLUSIONS: The epidemic of DF was caused by dengue virus- I from 2002 to 2006 in Guangzhou. Most of the patients had classic DF clinical manifestation with high percentage of hepatic injury. Few patients progressed to dengue hemorrhagic fever.
