Pancreatic Autoantibodies Are Associated with Reactivity to Microbial Antibodies, Penetrating Disease Behavior, Perianal Disease, and Extraintestinal Manifestations, But Not with NOD2/CARD15 or TLR4 Genotype in a Hungarian IBD Cohort

PAB autoantibodies in combination with ASCA or anti-glycan antibodies increase the sensitivity for detecting CD, especially isolated colonic CD. Antibody response to PAB was associated with complicated disease phenotype and extraintestinal manifestations in this Eastern European IBD cohort.
