Abstract

BACKGROUND/AIMS
Recently, nucleotide sequences from a novel virus, termed hepatitis G virus (HGV), were identified in serum from a patient with cryptogenic hepatitis and suggested as agent of non A-E hepatitis. HGV has been isolated from patients with various liver diseases but clinical implications of this new agent remain largely unresolved. In Korea, the etiology of substantial fraction of hepatitis has remained undefined and there has been no report concerning HGV.
METHODS
To determine the infection rate of HGV, RT-PCR of 5 UTR of HGV was performed, and to understand the clinical implication of HGV, medical records of 115 patients with various liver diseases were reviewed. Of 115 patients, 63 were male and 52 were female. Their mean age was 44 years (19-74) and their mean AST and ALT were 121.3+278.7 IU/L and 172.2+253.3 IU/L, respectively. Of 115 patients, 58 (50.4%) had no specific cause of liver diseases, 37 (32.2%) were infected with hepatitis B and/or C virus and 20 (17.4%) had non-viral identifiable liver diseases.
RESULTS
1. HGV RNA was detected in 15 (13.0%) patients of 115 patients. 2, Among the 15 HGV RNA positive cases, 7 were male and 8 were female. Their mean age was 48 years (19-72) and their mean AST and ALT were 71.9+45.2 IU/L, 97.4+66.8 IU/I respectively. 3. HGV RNA was detected in 8(13.8%) of 58 patients without obvious causes of their liver diseases and in 7 (18.9%) of 37 patients infected with HBV and/or HCV. However, HGV RNA was not detected fram 20 patients with non-viral liver diseases such as alcoholic liver diseases, autoimmune hepatitis, PBC, or fatty liver. 4. HGV RNA was detected in 5 (19.2%) of 26 patients with acute hep- atitis, in 6 (9.4%) of 64 patients with chronic hepatitis, in 1 (14.3%) of 7 patients with liver cirrhasis, and iB 3 (27.3%) Of 11 pafients with hepatocellular caIcinoma. 5. These was no slatistically significant difference in sex, age, history of transfusion, serum ALT level, etiologies and status of liver diseases between HGV RNA positve and negative group.
CONCLUSIONS
the prevalence of HGV infection is quite high among the patients who have no specific cause of acute or chronic liver diseases and HGV can be coinfected with HBV and/ar HCV infection in Korea.
