Alterations of glucose metabolism in chronic liver disease.
The prevalence of glucose intolerance has been studied by oral glucose tolerance test in 670 patients affected by chronic liver disease. The glycometabolic status was evaluated by criteria given by WHO in 1980. Sixty-nine subjects appeared to be affected by chronic persistent hepatitis and 140 by chronic active hepatitis. In these patients the prevalence of diabetic responses (DR) did not differ much from that of the general population in our geographic area. In contrast, a markedly higher frequency of DR appeared in a cirrhotic group of 401 patients compared to non-cirrhotic subjects. The cirrhotics, divided according to different disease stages, showed a higher DR frequency in decompensated patients than in well compensated patients, the prevalence reaching 63% in the former subgroup. The coincident presence of hepatocarcinoma - documented in 60 other cirrhotic patients - does not modify the prevalence of diabetes. Other risk factors for diabetes such as age, sex, and family history have been considered. Our results suggest that: (1) all these factors seem not to play a major role in the pathogenesis of alterations of glucose metabolism in patients suffering from chronic liver disease, and therefore (2) liver cirrhosis by itself might be a risk factor in the disturbance of glucose tolerance.
