Disorder of Glucose Metabolism and Therapy: Implications on the Natural History of Advanced Chronic Liver Disease.

Introduction: Hepatogenous diabetes (HD) is a disorder of glucose metabolism (DGM) that develops as a complication of advanced chronic liver disease (ACLD) with an estimated prevalence of 20-70%. It appears to be associated with a larger number of decompensations, but its impact on the natural history of the disease is unclear. The treatment of DGM is hampered by the fact that some therapeutic agents are associated with a risk of complications in ACLD. The aim of this work was to study DGM in a population of patients with ACLD: prevalence, liver disease decompensation episodes, mortality analysis and study of the impact of antidiabetic therapies in patients with ACLD who developed DGM. Materials and Methods: A cohort of consecutive patients with ACLD without previous DGM, who attended a Hepatology clinic in the period of January to June 2015 was selected. Follow-up was carried out for 5 years. Data on age, gender, date of diagnosis and etiology of ACLD, Child-Pugh and MELD-Na classifications at enrollment, development of DGM, and antidiabetic therapy were collected. Logistic regression models for hospitalizations due to decompensated ACLD, ascites, hepatic encephalopathy (HE), upper gastrointestinal bleeding (UGB), hepatocellular carcinoma (HCC), portal vein thrombosis (PVT), infectious complications, acute-on-chronic liver failure (ACLF), and death were built. A survival analysis for patients with and without DGM was also performed. Treatment effectiveness for patients with DGM was assessed. Results: Initially, 221 patients were included, 154 (69.7%) of whom developed DGM after the diagnosis of ACLD. DGM patients presented a significantly higher number of hospitalizations. Odds ratio (OR) for death was not significantly related with DGM. At 5 years of follow-up, 68.9% of patients with DGM were alive, against 81.8% without DGM ( Conclusion: DGM occurs with high prevalence in patients with ACLD and it seems to be related to more hospitalizations, which highlights the importance of its early identification and appropriate therapeutic approach. In the absence of contraindications, biguanides should be considered for treatment of patients with ACLD and DGM as they appear to be associated with a tendency to better outcomes and may present some advantage in terms of survival.
