[The importance of thyroid hormone determination in the course of acute and chronic liver diseases].

The RIA values of thyroid hormones in the course of acute and chronic liver disease were studied to see whether they were related to the severity of the picture in a series of 50 healthy subjects and 133 with various hepatopathies: 26 with acute viral hepatitis, 18 with alcoholic liver disease, 16 with alcoholic cirrhosis without ascites and 33 with ascites, 14 non-alcoholic cirrhosis without ascites and 24 with ascites. A reduction in T3 proportional to the seriousness of the clinical and laboratory findings was noted in chronic forms, whereas both T3 and T4 were high in acute viral hepatitis. There was no difference in T3 values in alcoholic and non-alcoholic cirrhosis of similar gravity, showing that the fall in serum T3 is not a specific alcohol-induced lesion. T3 less than 25 ng/100 ml proved the best index in the prediction of mortality (chi 2 = 20,5; p less than 0,0005).
