The study of efficacy and prognosis in corticosteroid treated autoimmune pancreatitis / 中华消化杂志

ABSTRACT

Objective To explore the long-term effect, prognosis and administration of corticosteroid treatment on autoimmune pancreatitis (AIP). Methods Clinical data were analyzed in 13 diagnosed and followed up AIP patients of Peking Union Medicine College Hospital during August 2004 to August 2008. Results Of 13 patients, 12 were males and 1 was female, with a mean age of 58.7 years old, and a mean follow-up of 30 months. Of 11 patients compliated with bile duct disease,biliary stents were placed in 9 patients and already taken out. Corticosteroid treatment was received by cured patients. The average corticosteroid therapeutic time was 9.2 months, 7.9 months in 6 biliary stent placed patients, 13.4 months in corticosteroid treated alone patients, the statistical difference was significant (P = 0. 023). Serum inflammatory parameters normalized range from 5. 3 to 8.8 weeks. After corticosteroid treatment, pancreas enlargement improved in all patients at the first imaging reexamination (1.0 to 11.3 weeks), pancreatic size normalized in 9 patients with an average of 16.6 weeks corticosteroid treatment. No relapsing sign was found with imaging examination during follow-up. Of 8 newly onset diabetes patients, glucose level normalized in 4 patients after corticosteroid treatment. Two patients complicated with autoimmune hepatitis developed early hepatic cirrhosis symptoms at the end of the follow-up. Swollen submandibular gland enlargement relapsed in one patient after corticosteroid withdrawn for six months. Conclsion AIP patients responsed well to corticosteroid treatment. Placement of biliary stent could shorten corticosteroid therapeutic time.Patients with bile duct complications and newly onset diabetes could partially relieve after the corticosteroid treatment, the prognosis of patients with autoimmune hepatitis complications was relatively poor.
