Clinical and Immunopathologic Profile of Mexican Patients with IgG4 Autoimmune Pancreatitis.

Autoimmune pancreatitis is part of the spectrum of IgG4-associated diseases. Its diagnostic criteria and histological subtypes have been formally proposed recently and although based on current data it has been suggested that there are differences in clinical presentation among populations, more research is needed to properly establish if this heterogeneity exists. In this paper, we describe 15 cases of autoimmune pancreatitis diagnosed at a Mexican centre of reference, all of them associated to the lymphoplasmocytic sclerosing pancreatitis variant.

When should we be concerned about pancreatic necrosis? Analysis from a single institution in Mexico City.

Background/aim: Although pancreatic necrosis classifies acute pancreatitis (AP) as severe, many patients with tomographic evidence of necrosis never develop systemic complications. Our aim was to analyze the incidence of pancreatic necrosis, organ failure (OF), and the relationship between them.

Methods: Medical records from 165 patients with a first AP episode and in whom a contrast-enhanced computed tomography (CECT) was performed were analyzed.
