Abstract
Autoimmune pancreatitis is a recently defined nosological entity, which accounts for 4.6-6% of all forms of chronic pancreatitis and is often associated with other autoimmune diseases, particularly Sjögren's syndrome. Possession of the HLA DRB1*0405-DQB1*0401 genotype confers a risk for the development of autoimmune pancreatitis. Autoantibodies against carbonic anhydrase II and lactoferrin are frequently present in affected subjects and are suspected to have a pathogenic role. A link between gastric infection by Helicobacter pylori and autoimmune pancreatitis has been hypothesized. We used in silica protein analysis and search for HLA binding motifs to verify this hypothesis. We ...
