Background/Aim: Autoimmune pancreatitis (AIP) responds rapidly and dramatically to steroid therapy. The aim of this study was to evaluate pancreatic exocrine and endocrine function in patients suffering from AIP both before and after steroid therapy. Patients andMethods: Fecal elastase 1 and diabetes were evaluated before steroid therapy and within 1 month of its suspension in 21 patients (13 males and 8 females, mean age 43 ± 16.5 years) diagnosed as having AIP between 2006 and 2008. Results: At clinical onset, fecal elastase 1 was 107 ± 126 µg/g stool. Thirteen patients (62%) showed severe pancreatic insufficiency (<100 µg/g stool), 4 (19%) had mild insufficiency (100–200 µg/g stool), while 4 (19%) had normal pancreatic function (>200 µg/g stool). Before steroids, diabetes was diagnosed in 5 patients (24%), all of whom had very low levels of fecal elastase 1 (<19 µg/g stool). Following steroids, fecal elastase 1 increased in all patients (237 ± 193 µg/g stool) and observed levels were significantly higher than those seen before steroids (p = 0.001). Conclusions: Patients suffering from AIP display exocrine and/or endocrine pancreatic insufficiency at clinical onset. These insufficiencies improve after steroid therapy.

Abstract

Background/Aim: Autoimmune pancreatitis (AIP) responds rapidly and dramatically to steroid therapy. The aim of this study was to evaluate pancreatic exocrine and endocrine function in patients suffering from AIP both before and after steroid therapy. Patients andMethods: Fecal elastase 1 and diabetes were evaluated before steroid therapy and within 1 month of its suspension in 21 patients (13 males and 8 females, mean age 43 ± 16.5 years) diagnosed as having AIP between 2006 and 2008. Results: At clinical onset, fecal elastase 1 was 107 ± 126 µg/g stool. Thirteen patients (62%) showed severe pancreatic insufficiency (<100 µg/g stool), 4 (19%) had mild insufficiency (100–200 µg/g stool), while 4 (19%) had normal pancreatic function (>200 µg/g stool). Before steroids, diabetes was diagnosed in 5 patients (24%), all of whom had very low levels of fecal elastase 1 (<19 µg/g stool). Following steroids, fecal elastase 1 increased in all patients (237 ± 193 µg/g stool) and observed levels were significantly higher than those seen before steroids (p = 0.001). Conclusions: Patients suffering from AIP display exocrine and/or endocrine pancreatic insufficiency at clinical onset. These insufficiencies improve after steroid therapy.
