Relapse rate and predictors of relapse in a large single center cohort of type 1 autoimmune pancreatitis: long-term follow-up results after steroid therapy with short-duration maintenance treatment.

Type 1 autoimmune pancreatitis (AIP), as a pancreatic manifestation of IgG4-related disease, shows a favorable prognosis in the short term. However, disease relapse is common in long-term follow-up, despite a successful initial treatment response. This study aimed to identify the predictors of relapse and long-term outcomes in patients with type 1 AIP.
