Pancreatitis as an extraintestinal manifestation of Crohn's disease (C
D) is controversial. We review the episodes of acute pancreatitis in p
atients with CD. Of 852 patients, 12 developed clinically overt pancre
atitis, reparesenting a frequency of 1.4% in a follow-up period of 10
years. In 10 patients, common causes of pancreatitis were excluded. In
2 patients, drug-induced disease (azathioprine, sulfasalazine) could
not be ruled out. Recurrence of pancreatitis was observed in only 2 pa
tients. Younger patients and those with active disease seemed more at
risk for development of pancreatitis. If prednisolone was needed for t
reatment of active CD, no adverse effect was observed for the pancreat
itis. Along with the clinical features, we studied autoantibodies agai
nst exocrine pancreas; the incidence of autoantibodies in patients wit
h pancreatitis was the same as in the controls who did not develop pan
creatic abnormalities. This does not support the hypothesis that acute
pancreatitis in CD is associated with the formation of pancreatic aut
oantibodies.
