Expert Opinion by Clinicians on the Use of Insulin Therapy in People with Hepatic Impairment

Abstract

People with type 2 diabetes mellitus (T2DM) have a higher risk of developing chronic liver disease (CLD) and its complications. T2DM, obesity, and insulin resistance are all strongly associated with nonalcoholic fatty liver disease (NAFLD). Conversely, people suffering from cirrhosis have reduced glucose tolerance in approximately 60% of cases, diabetes in 20% of cases, and insulin-mediated glucose clearance is lowered by 50% as compared with those who do not have cirrhosis. An exploratory review was conducted using existing published evidence from clinical studies on dosing and titrations of individual insulin formulations in people with CLD to optimize insulin dosage titration for minimizing hypoglycemia risk. This article discusses current hyperglycemia treatment techniques for patients with CLD as well as the consensus recommendations on insulin use in special populations with T2DM and hepatic impairment. Based on available evidence and expert diabetologists’ recommendations, careful insulin dose titration, customized glycemic targets, and frequent glucose screening are recommended for optimal glycemic management without hypoglycemia in CLD. Long-acting insulin should be avoided or used when short-acting insulin fails to provide adequate glycemic control with raised fasting blood sugar levels. While the patient’s glucose profile is being evaluated, the prandial insulin dose can be lowered by 25% initially. The dose can be titrated based on the patient’s postprandial glycemic expression and whether their food intake meets the Child–Pugh scores A and B categories. Titrating premixed insulins is difficult for patients in class C since their appetite and overall health are constantly compromised and in flux.
