ABSTRACT
Purpose: The major cause of chronic hepatitis is infections with hepatitis B virus and hepatitis C virus (HCV) globally. However, there exists sparse epidemiological data regarding the prevalence of HCV infection from India. Methodology: We carried out a cross-sectional study to estimate the prevalence of anti-HCV antibody among acute febrile illness cases aged between 1 and 65 years in Idar Taluk, Sabarkantha district, Gujarat state located in West India. A total of 702 serum samples collected from the study area during the year 2017, were screened for anti-hepatitis C IgG by enzyme-linked immunosorbent assay. The serum samples screened positive were then subjected to molecular testing for confirmation. Results: Among the 702 study participants screened, 16 cases were reported to be anti-HCV IgG positive with an estimated seroprevalence rate of 2.3% (95% confidence interval: 1.4%–3.7%). Out of the 16 cases, two samples were confirmed positive by molecular testing indicating active infection. When analysed phylogenetically, one strain was genotyped as HCV1b genotype, and the other one was clustered along with HCV3a genotype. Both the patients with hepatitis C infection were observed to be having a probable 1-year survival rate of 100% and a 2-year survival rate of 85% when the Child-Turcotte-Pugh classification was applied. Conclusion: The estimated seroprevalence of hepatitis C in Idar Taluk, Sabarkantha district, west India was 2.3%. HCV genotypes 1b and 3a were observed to be circulating in the study area.
ABSTRACT
Objective:To determine the frequency of anti-HCV antibody positivity in patients with non-liver disease complaints, to explore whether anti-HCV positive patients had been properly advised and visited hepatologists for further assessments, and to investigate their clinical characteristics as well as the HCV treatment status.Methods:A hospital based survey of non-liver disease patients with anti-HCV positive and their attending physicians was conducted to determine: 1. were the patients adequately advised of the implication of anti-HCV positive finding; 2. to what extent the patients were aware of potential chronic liver disease associated with HCV infection and whether they sought for further assessments and care of hepatologists.Results:A total of 295 294 non-liver disease patients were tested for anti-HCV antibody, and 2 778 of them were found to be positive (0.94%). However, only 45.10% (1 253/2 778) of the anti-HCV antibody (+) patients were referred to hepatologists and received HCV RNA test. In addition, 34.10% (312/915) and 1.42% (13/915) of them had already advanced to cirrhosis and hepatocellular carcinoma (HCC), respectively. Further analysis showed that the patients who declined antiviral therapy were older, with lower education and lower income, possessed poorer knowledge on the risk of chronic hepatitis C, and had more severe liver diseases. Surprisingly, 65% of the surveyed physicians did not know the genotype-guided treatment duration suggested by the guidelines. Alarmingly, 22% of the surveyed physicians did not know the standard assays for the diagnosis of HCV infection.Conclusions:Our findings highlight the challenge and hidden enormous burden of chronic HCV infection among patients with non-liver disease complaints in China.

ABSTRACT
To investigate the association between hepatocellular carcinoma(HCC) and infection of hepatitis B virus(HBV) and hepatitis C virus(HCV) in an HBV endemic area , a case-control study of 254 patients with HCC and of 1,270 age and sex matched health control subjects was done. Among the 254 HCC patients 166(65.4%) were positive for hepatitis B surface antigen(HBsAg), 49(19.3%) were positive for HCV antibody(anti-HCV Ab). The crude odd ratio of patients with HBsAg was 36.1(95% CI :22.4-58.2) and with anti-HCV Ab was 9.0(95% CI :5.5-14.6). In an analysis, which HBsAg(-), HBcAb(-), anti-HCV Ab(-) group was chosen as referent group, odd ratio of HBsAg(+) group was 14.4(95% CI: 7.2-28.9) and of anti- HCV Ab(+) was 10.7(95% CI: 2.9-40.0). Odd ratio of anti-HCV Ab(+), HBsAg(+) group and anti-HCV Ab(+), HBsAg(-), HBcAb(+) group for HCC were elevated to 27.3(95% CI : 9.0-82.9) , 15.9(95% CI:7.1-35.8) respectly. The odd ratio of anti-HCV Ab(-), HBsAg(-), HBcAb(+) group was 2.4(95% CI : 1.1-5.0). These result suggested that HBV and HCV were associated with HCC. In HBV endemic area patients with HBcAb alone should be considered risk group for HCC.
