Abstract
To clarify the role of hepatitis G virus (HGV) infection in liver dysfunction following allogeneic BMT, we examined cryopreserved serum samples from 33 patients who had a history of blood transfusions before BMT and whose serum samples had been stored periodically, before BMT, on day 100, and thereafter for the presence of HGV-RNA and hepatitis C virus (HCV)-RNA by reverse transcription polymerase chain reaction. Nineteen patients (58%) out of 33 were positive for HGV-RNA before BMT and 10 for HCV-RNA. All patients positive for HCV-RNA were also positive for HGV-RNA. Patients were divided into three groups according to their viral status before BMT; namely, the G+C+ group (n = 10), the G+C− group (n = 9) and the G−C− group (n = 14). Two patients in the G−C− group became positive for HGV-RNA after BMT. One patient in the G+C− group suffered an acute exacerbation of hepatitis, with GPT levels reaching over 1000 IU/l, 2 and 3 years after BMT, showing quite a different clinical course from those in the G+C− group. Excluding these three patients, GPT levels of the patients in the G+C+ group were significantly higher after day 100 and remained higher than those of patients in the G+C− and G−C− groups for at least 4 years. There were no significant differences in post-transplant GPT levels between the G+C− group and the G−C− group at any time point. Of the seven patients followed-up for 5 to 10 years, three patients became HGV-RNA-negative, while four remained positive. In the absence of HCV co-infection, the behavior of GPT values post transplant in patients with HGV infection did not differ from those without HGV infection. With respect to the patient who was G+C− and showed high values of GPT 2 and 3 years post transplant, we suspect that his liver dysfunction might have been caused by some unknown virus or etiology.
