Abstract

The parotid gland function and structure was studied in 30 patients with biopsy-proven alcoholic cirrhosis and in 43 age- and sex-matched alcoholic and nonalcoholic control subjects. Mean simulated parotid saliva flow rate was significantly (p < 0.05) lower in patients with alcoholic cirrhosis as compared with alcoholic and nonalcoholic control subjects. A similar reduction was observed in mean basal parotid saliva flow rate in patients with alcoholic cirrhosis that reached statistical significance (p < 0.05) in comparison with nonalcoholic control subjects. In addition, the concentration of sodium, bicarbonate, and total proteins in stimulated parotid saliva was significantly (p < 0.005) lower in patients with alcoholic cirrhosis as compared with the two groups of control subjects. Sialograms in 6 patients with alcoholic cirrhosis did not reveal any obstructive lesion in the primary parotid duct or its branches. Histology of salivary tissue revealed an increase in the interstromal fatty infiltration, edema, and fibrosis without evidence of inflammatory reaction in 5 patients as compared with the control subjects. These data provide evidence for marked parotid gland dysfunction in patients with alcoholic cirrhosis presumably due to metabolic derangement and altered parotid gland structure. © 1989.
