Evaluation of adrenal function in hemodynamically stable patients with liver cirrhosis

Aim of the study
To estimate the prevalence of adrenal insufficiency (AI) in hemodynamically stable cirrhotic patients and to evaluate the potential association with patients’ clinical characteristics, cirrhosis etiology and liver disease severity.

Material and methods
The cross-sectional study included 132 stable liver cirrhosis patients. Severity of liver disease was graded using the Child-Pugh classification and Model for End-stage Liver Disease (MELD) score. The adrenal function was evaluated by measuring basal and peak cortisol after 60 minutes following the short Synacthen test (SST). Differences in terms of demographic data, clinical information and liver disease severity were compared between cirrhotic patients with and without AI.

Results
Out of 132 cirrhotic patients, 86 patients had evidence of AI based on the peak serum cortisol value while the prevalence was lower (67 patients out of 132) when basal cortisol level was taken as the basis. A total of 82 patients were classified as Child-Pugh class C, with an average MELD score of 20 ±7.1. Most patients with AI had Child-Pugh class C. Patients with AI had a higher prevalence of ascites, gastrointestinal hemorrhage, and hepatic encephalopathy, a higher MELD score and a lower serum sodium level compared to patients with normal adrenal function. AI was not related to the etiology of cirrhosis but was related to the severity of liver disease and the degree of hyponatremia.

Conclusions
Adrenal insufficiency is common among hemodynamically stable patients with cirrhosis. It is related to the severity of liver disease and the degree of hyponatremia.
