摘      要：Background:Concurrent extrahepatic autoimmune disorders(CEHAID)are frequently observed in autoimmune hepatitis(AIH).It is not clear whether there is any prognostic significance of CEHAID on *** aim of this study was to examine the prognostic impact of CEHAID and the correlation with the disease severity of ***:This study included 65 hospitalized subjects who fulfilled the accepted criteria for AIH during an 8-year period(2009–2016).All records were manually screened for presence of associated autoimmune *** severity of AIH was assessed by liver laboratory tests including the ratio of aspartate aminotransferase to alanine aminotransferase(AST/ALT)and liver ***:Among the enrolled patients,52(80%)were female(median age 61 years,IQR 45–75).Fifty-six(86.2%)were classified as type-1 *** 26(40%)patients at least one additional extrahepatic autoimmune disease was ***-four subjects were referred to our hospital because of acute presentation of AIH(supposed by an acute elevation of hepatic enzymes)for subsequent liver biopsy resulting in initial diagnosis of *** group was stratified into 3 subgroups:(A)AIH alone(n=14);(B)overlap with primary biliary cirrhosis(PBC)/primary sclerosing cholangitis(PSC)(n=11);and(C)with CEHAID(n=9).AST/ALT ratio was the lowest in subgroup C(median 0.64,IQR 0.51–0.94;P=0.023),compared to subgroup A(median 0.91,IQR 0.66–1.10)and subgroup B(median 1.10,IQR 0.89–1.36).Patients with AIH alone showed a trend to the highest grade of fibrosis(mean 2.3;95%CI:1.5–3.0)with no statistical significance compared to subjects with CEHAID(lowest grade of fibrosis;mean 1.5;95%CI:0.2–2.8;P=0.380)whereas the ongoing inflammation was ***:AST/ALT ratio and extent of fibrosis were lower in subjects with AIH and CEHAID,compared to subjects with only ***,the occurrence of CEHAID might be a predictor for lower disease severity of newly diagnosed acute onset AIH,possibly caused by an e
