Serum selenium concentrations in chronic pancreatitis and controls.
BACKGROUND
In the light of the recent hypothesis that one cause of pancreatic damage may be related to the toxic action of oxygen free radicals [Braganza JM. The pathogenesis of pancreatitis. Manchester: Manchester University Press; 1991; Braganza JM. A framework for the aetiogenesis of chronic pancreatitis. Digestion 1998;59(Suppl. 4):1-12], we were prompted to assess the role of selenium in pancreatic disease.


OBJECTIVE
The objective of the study was to establish whether or not there is any correlation between selenium levels and the degree of impairment of exocrine pancreatic function in patients suffering from chronic pancreatitis.


METHODS
Two groups of subjects were recruited, the first consisting of 38 patients with clinically quiescent chronic pancreatitis of alcoholic origin and the second of 48 control subjects selected from among healthy volunteers attending our Transfusion Centre.


METHODS
Body mass index, smoking and drinking habits were evaluated and selenium serum levels were assayed in all subjects. The patients with pancreatic disease were subdivided into three groups on the basis of lipase output assayed with a duodenal probe. RESULTS.: Selenium serum levels in the chronic pancreatitis group as a whole were found to be significantly lower than in the control group, but when they were analysed in the three distinct subgroups, a significant difference was found against control group only in the groups with severe and moderate exocrine pancreatic insufficiency.


CONCLUSIONS
The mean serum selenium levels were lower in chronic pancreatitis patients than control.
