BACKGROUND/AIMS: The aim of this study was to investigate the effects of being overweight on autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) patients. METHODOLOGY/ RESULTS: 44 AIH and 95 PBC patients were enrolled in this study. Body weight and body mass index (BMI) of AIH (57.6 +/- 10.4 kg and 23.8 +/- 2.9 kgm(-2), respectively) were higher than those of PBC (51.6 +/- 7.0 kg and 22.0 +/- 2.6 kgm(-2), respectively) (P < 0.001). The prevalence of overweight patients in AIH was also higher than those in PBC (P < 0.005). Being overweight and having 25 < or = BMI < 30 did not affect the progression of hepatic fibrosis in AIH and PBC. In comparison with the non-overweight with PBC, overweight patients with PBC tended not to be symptomatic, such as having itching or fatigue (P = 0.027). CONCLUSIONS: Clinicians should be aware that not only non-alcoholic fatty liver disease but also PBC patients might be included among the overweight hepatic disease patients with unknown etiology.
