Investigation of anti-HCV in 391 serum samples in China
Insights
This study found a high prevalence of Hepatitis C Virus (HCV) antibodies in northern China, particularly among Hepatitis B Virus (HBV) positive blood donors. This highlights a significant public health concern for HCV infection in the region.
Area of Science:
- Hepatology
- Virology
- Epidemiology
Background:
- Hepatitis C Virus (HCV) infection is a significant global health issue.
- Understanding HCV prevalence is crucial for public health interventions, especially in regions with co-existing viral hepatitis like Hepatitis B Virus (HBV).
- Limited data exists on HCV distribution in northern China.
Purpose of the Study:
- To determine the prevalence of anti-HCV antibodies in different populations in northern China.
- To investigate the co-infection rate of HBV and HCV.
- To report the initial findings on anti-HCV distribution in this specific Chinese population.
Main Methods:
- Enzyme-Linked Immunosorbent Assay (ELISA) was used to detect anti-HCV antibodies.
- Serum samples were collected from 391 individuals, including healthy blood donors, HBsAg positive blood donors, and liver disease patients.
- Serum ALT levels were assessed in a subset of HBV-HCV co-infected individuals.
Main Results:
- Anti-HCV antibodies were detected in 4.6% of healthy donors, 32.4% of HBsAg positive donors, and 5.4% of liver disease patients.
- Hepatitis B Virus-Hepatitis C Virus (HBV-HCV) co-infection was observed in 24 individuals.
- Abnormal serum ALT levels were found in 40% of the HBV-HCV co-infected patients analyzed.
Conclusions:
- A surprisingly high rate of HCV infection was found in both healthy and HBsAg positive blood donors in northern China.
- The study underscores the need to investigate the reasons for the elevated HCV prevalence.
- This research provides the first report on anti-HCV distribution in this specific Chinese population, highlighting a potential public health concern.
Abstract:
391 serum samples from healthy blood donors, HBsAg positive blood donors and patients with different kinds of liver diseases in northern China were tested for anti-HCV by ELISA. Of the healthy donors, 4.6% (7/151) were anti-HCV positive; of the HBsAg positive donors, 32.4% (24/74) were positive; and of the liver disease patients, 5.4% (9/166) were positive. Among the 24 cases of HBV-HCV double infection, 10 were assayed for serum ALT level. 40% (4/10) of them were abnormal. The causes of the surprisingly high rate of HCV infection, both in healthy donors and in HBsAg positive donors, were discussed. This is the first report on the distribution of anti-HCV in certain population in China.
