title: Exocrine dysfunction of the pancreas in patients with chronic polyarthritis.
abstract: We studied the extent to which exocrine dysfunction of the pancreas is seen among patients with severe chronic polyarthritis and whether it might account for some gastrointestinal symptoms. Our series consisted of 50 such chronic polyarthritis cases; most had rheumatoid arthritis but had neither diagnosed or suspected pancreatitis nor primary Sjögren's syndrome. They were asked about gastrointestinal (GI) and sicca symptoms. The exocrine function of each pancreas was evaluated by the fecal elastase-1-enzyme test. Thirty-two patients had GI symptoms at least weekly. Forty had sicca eye syndrome and 26 had dry mouth. There were two cases (4%; 95% confidence interval, 1-14%) with abnormally low fecal elastase-1-enzyme test level. Chronic GI and sicca symptoms are frequent among patients with severe chronic polyarthritis. Secondary Sjögren's syndrome may cause exocrine insufficiency in the pancreas. That circumstance was not common here, but it is worth remembering because it can be diagnosed by a noninvasive method, and enzyme preparation treatment is available for the symptoms, especially for postprandial pain and distention of the stomach.
