Abstract Background Chronic hepatitis C (HCV) and B viruses (HBV) represent the commonest global causes of liver cirrhosis. Other etiologies of non-viral cirrhosis such as autoimmune, metabolic, vascular, or biliary diseases are underestimated. The study aimed to identify causes, clinicoepidemiological characteristics, and outcome of non-B non-C liver cirrhosis. This Egyptian multicenter study recruited patients with liver cirrhosis excluding HCV and HBV. Clinical evaluation and the mortality were recorded. Laboratory, radiological, and histopathological assessment to diagnose the etiology was performed. Results One hundred eighty-eight patients were included: 54.3% were males. Autoimmune hepatitis (AIH) was the most common cause of cirrhosis (28.2%), followed by Budd-Chiari syndrome (BCS) in 25%, and cryptogenic in 23.9%. Metabolic causes such as Wilson’s disease, non-alcoholic steatohepatitis (NASH), and hemochromatosis were reported in 7.4%, 3.2%, and 1.1%, respectively. Biliary and cardiac cirrhosis were less frequent. Older age was prevalent in hemochromatosis (67.5 ± 17.7 years) and NASH (60.7 ± 11), while young age in Wilson’s disease (29.5 ± 14.8) and secondary biliary cirrhosis (14.8 ± 4.8). Rural residence was common (60.6%). Mortality was reported in BCS (40.4%), cryptogenic (28.9%), cardiac (25%), Wilson’s disease (21.4%), AIH (17%), and NASH (16.7%). Hepatocellular carcinoma complicated 10.6% of cases. A significantly high percentage of patients had decompensated cirrhosis. Child–Pugh class and rural residence were significant predictors of mortality. Conclusion This first report on non-B non-C cirrhosis in Egypt revealed a high prevalence of AIH, BCS, and cryptogenic cirrhosis. Advanced Child class and rural residence were the predictors of mortality.
