[Blood calcitonin in alcoholic cirrhosis]

In spite of an important metabolic role of the liver in the synthesis and degradation of hormonal peptides and seco-steroïds, the clinical occurrence of disturbed regulation of calcium and phosphorus metabolism is rare in hepatic disorders. 23 patients suffering from alcoholic cirrhosis were studied. All had normal plasma calcium and phosphorus concentration as well as immunoreactive parathyroid hormone levels. 25 hydroxyvitamin D3 levels were decreased. Immunoreactive calcitonin were increased in relation to the increase in plasma alkaline phosphatase activity. The causes and consequences of these endocrine disturbances are discussed.
