[C-type hepatitis in spontaneous intracerebral hemorrhage].

The prevalence of hepatitis C virus (HCV) in 139 cases of spontaneous intracerebral hemorrhage (ICH) was investigated with regard to a diagnosis of hypertension. Patients under 30 and over 79 years of age were omitted from this study, and those with complicating malignancies and undergoing anti-coagulation or antiplatelet therapy were also excluded. The prevalence of HCV was significantly higher among the ICH group as a whole (19 out of 139 cases, p < 0.05) especially in the non-hypertensive group (7 out of 29 cases, p < 0.01), compared to the control group (7 out of 140 cases without ICH). The non-hypertensive HCV-positive group (7 cases) had significantly higher GOT and GPT levels, prolonged PT and a-PTT values, and lower platelet counts, compared to the hypertensive HCV-negative group (74 cases). The HCV antibody titers did not differ among the HCV-positive groups. The results suggest that chronic hepatitis due to HCV infection is a major risk factor for spontaneous intracerebral hemorrhage, especially in non-hypertensive patients.
