Summary
Hepatitis G virus/GB virus C (HGV/GBV-C) was recently identified. However, current evidence does not support HGV/GBV-C as a cause of non-A-E viral hepatitis.
Area of Science:
- Hepatology
- Virology
- Epidemiology
Background:
- A significant percentage of viral hepatitis cases are not attributable to known hepatitis viruses (non-A-E).
- A novel virus, hepatitis G virus/GB virus C (HGV/GBV-C), was recently isolated by independent research groups.
- HGV/GBV-C is detected in approximately 2% of US blood donations.
Purpose of the Study:
- To review the isolation methods and epidemiological data of HGV/GBV-C.
- To evaluate the etiological role of HGV/GBV-C in non-A-E viral hepatitis.
Main Methods:
- Review of viral isolation techniques.
- Analysis of existing epidemiological data on HGV/GBV-C prevalence and association with hepatitis.
Main Results:
- Details of HGV/GBV-C isolation by two independent groups are presented.
- Epidemiological data regarding HGV/GBV-C prevalence in blood donations are discussed.
- The current evidence does not establish HGV/GBV-C as a causative agent of non-A-E viral hepatitis.
Conclusions:
- The isolation of HGV/GBV-C represents a significant advancement in identifying potential causes of non-A-E hepatitis.
- Despite its identification, the available epidemiological data do not support HGV/GBV-C's role in causing non-A-E viral hepatitis.
- Further research may be needed to fully elucidate the significance of HGV/GBV-C in liver disease.
