Abstract

α1-Antitrypsin deficiency is a genetic disorder commonly associated with pulmonary and hepatic injury. Low serum levels of this glycoprotein result in an imbalance between circulating protease and protease inhibitors, which is thought to play a role in the development of emphysema. In recent studies, a protease-to-protease inhibitor imbalance in patients with α1-antitrypsin deficiency was thought to be a mechanism contributing to the development of chronic pancreatitis. The heterozygous phenotype and low levels of this glycoprotein have been reported to occur more frequently in patients with chronic pancreatitis than in healthy controls. We report a patient with Pi-SS phenotype α1-antitrypsin deficiency and chronic pancreatitis complicated by recurrent pancreatic pseudocysts and chronic abdominal pain. Our case supports the association between chronic pancreatitis and α1-antitrypsin deficiency. Furthermore, this case provides support for the use of pancreatic stent drainage in the management of intractable abdominal pain in patients with chronic pancreatitis and a dominant stricture.
