title: Hepatitis C virus (HCV) infection as a risk factor for spontaneous intracerebral hemorrhage: hospital based case-control study.
abstract: Hepatitis C Virus (HCV) infection was investigated as a risk factor for intracerebral hemorrhage (ICH) by HCV antibody screening in 462 patients with ICH and 462 control patients with cerebral infarction matched by age and sex. Laboratory examinations of hemostatic parameters and cholesterol level were also performed in patients with ICH. HCV infection was significantly more frequent in patients with ICH than controls (8.7% vs 3.5%, P< 0.01). ICH patients with HCV infection had significantly higher L-alanine:2-oxoglutarate aminotransferase level (P< 0.001), lower cholesterol level (P< 0.05), lower platelet count (P< 0.05), and longer prothrombin time (P< 0.01) than ICH patients without HCV infection, although most of these values were within the normal range. These results demonstrate that HCV infection is a risk factor for spontaneous ICH. Subclinical clotting disorder and/or vessel wall friability resulting from hypocholesteremia may be associated with ICH in patients with HCV infection.
