| Outline of Final Research Achievements |
HCV causes extrahepatic manifestations. We investigated relationship between oral environment and liver disease. The patients with HCV-infected liver diseases treated with IFN therapy examined for Candida infection, oral lesions, salivary flow, and serological assays. We also evaluated the association between periodontitis and liver diseases in patients with HCV and/or HBV infection. Salivary flow decreased in all subjects throughout the course of IFN treatment and returned after the end of treatment. According to multivariate analysis, one factor, the presence of oral mucosal lesions, was associated with the detection of Candida. According to multivariate analysis, five factors were associated with periodontal disease as platelet count below 80000, brushing teeth only once a day, current IFN treatment, aged 65 years or older and obesity. Not only the disease of the oral mucosa but also periodontal disease may be involved in pathologic condition of a liver disease.
