Leptin as a Key Player in Insulin Resistance of Liver Cirrhosis? A Cross-Sectional Study in Liver Transplant Candidates
Insulin resistance is associated with increased risk of death and liver transplantation in the cirrhotic population, independent of disease aetiology. However, factors accounting for insulin resistance in the context of cirrhosis are incompletely understood. This study aimed to investigate the assoc...

Logistic regression analysis identified leptin and triglycerides as independent predictors of insulin resistance (OR 1.247, 95% CI 1.076−1.447, <i>p</i> = 0.003; OR 0.357, 95% CI 0.137−0.917, <i>p</i> = 0.032.).

Progressively increasing adiponectin levels elicited a positive effect on glucose homeostasis, but not insulin sensitivity across disease stages.https://www.mdpi.com/2077-0383/9/2/560liver cirrhosisinsulin resistanceleptinadiponectin |

Insulin resistance is associated with increased risk of death and liver transplantation in the cirrhotic population, independent of disease aetiology.
