The authors collected 188 cases of fulminant hepatitis with encephalopathy cases, including: 3 cases of hepatitis (2%), 3 cases of hepatitis B virus infection (2%), 106 cases of hepatitis B (56%), 64 cases (34%) of non-A, non-B hepatitis and 12 cases (6%) of drug-induced liver disease. Eight patients with hepatitis B and four non-A non-hepatitis B patients had hepatitis history of exposure; 15 patients with hepatitis B and 4 non-A non-B patients had a history of blood transfusions. There are no known sources of infection in 45% of hepatitis B patients and 77% of non-A non-B hepatitis patients (P <0.001). Among hepatitis B cases, 43% were male, whereas 28% were non-A non-B hepatitis (P = 0.071). The age distribution of hepatitis B cases: 0% under 15 years of age; 84% of 15 to 44 years old, 16% over 45 years of age. The distribution of non-A, non-B hepatitis cases was 10%, 61%, and 29% in the above-mentioned age group, respectively, which was significantly different from that of hepatitis B cases
