[Hepatogenic diabetes: three cases report and literature review].

Abstract

Hepatogenic diabetes (HepD) is a form of diabetes where the primary pathogenesis is a liver disease, usually cirrhosis, complicated by the development of portal hypertension with the formation of porto-caval shunts. In the development of HepD, in addition to traditional risk factors for carbohydrate metabolism disorders, the pathogenetic features of liver diseases play a significant role. However, the exact mechanism of HepD development remains unclear, and several questions are still open for discussion. Despite having distinct pathophysiological and clinical features, hepatogenic diabetes is currently not considered as an independent disease. This is likely due to the difficulties in differentiating between types of diabetes due to the bidirectional relationship between glucose metabolism disorders and chronic liver diseases. It is known that diabetes negatively affects the development and progression of chronic liver diseases of various etiologies, and their combination is associated with worse clinical outcomes in terms of mortality, the occurrence of liver decompensation, and the development of hepatocellular carcinoma (HCC). Unfortunately, early diagnosis and the selection of optimal therapeutic strategies for diabetes may be challenging due to the lack of established clinical guidelines and the presence of comorbidities in patients with HepD.
