The salivary glands are structurally similar to the exocrine pancreas and may be involved in the course of diseases of autoimmune origin (sclerosing cholangitis, ulcerative rectocolitis, primary biliary cirrhosis). For a not-yet-quantified proportion of chronic pancreatitis (CP) cases, a possible autoimmune pathogenesis has been postulated. The aim of the study was to assess the frequency of salivary ductal system abnormalities in patients with CP. Fifty-one patients with CP consecutively admitted to our center were studied (44 men, seven women; mean age, 48.2 +/- 10.8 years). The mean duration of disease was 11.7 years (range, 1-37 years); 44 (86%) of 51 patients had pancreatic calcifications, 25 (49%) of 51 diabetes, 25 (52%) of 48 steatorrhea, and 32 (63%) of 51 underwent pancreatic surgery. As a control group, we studied 10 patients of whom four with liver cirrhosis (three alcoholic and one posthepatitis; three men, one woman; mean age, 57 +/- 12.5 years), and six with temporomandibular pain (five men and one woman; mean age, 42 +/- 10.3 years). The patients were given parotid sialography, the findings being read by two independent observers. In two CP patients, parotid sialography was unsuccessful. Fifteen (31 %) of 49 patients and none of the 10 control patients exhibited abnormalities of the glandular ducts compatible with chronic inflammation of the salivary ducts (p = 0.039). None of the CP patients had salivary intraductal calcifications. Findings of parotid ductal abnormalities are frequent in the course of CP and may indicate a common pathogenetic mechanism, even of an immune type.
