Prevalence of hepatitis-G virus and hepatitis-C virus infection in patients with non-Hodgkin's lymphoma.

Several studies have reported that hepatitis-C virus may have a role in the development of non- Hodgkin's lymphoma. Hepatitis-G virus has hepatitis-C virus like characteristics. The possible association between hepatitis-G virus infection and non-Hodgkin's lymphoma is not clear. The aim of this study was to determine the prevalence of hepatitis-G virus and hepatitis-C virus infection in patients with non-Hodgkin's lymphoma without blood transfusion. Forty-four patients with non-Hodgkin's lymphoma were enrolled in the study. Serum samples derived from the patients were tested for antibodies against hepatitis-C virus by ELISA. Hepatitis-G virus and hepatitis-C virus RNA were detected by reverse transcription-polymerase chain reaction. Only two of 44 patients (5%) with non-Hodgkin's lymphoma were positive for Anti- HCV and hepatitis C virus RNA. One patient had low grade non-Hodgkin's lymphoma with follicular mixed histopathology while the other had intermediate grade with diffuse large cell histopathology. Hepatitis-G virus infection was detected in none of the patients. We concluded that hepatitis-G virus does not seem to be in association with non-Hodgkin's lymphoma.
