Critical illness-related corticosteroid insufficiency in cirrhotic patients with acute gastroesophageal variceal bleeding: risk factors and association with outcome*.

OBJECTIVES

Critical illness-related corticosteroid insufficiency can adversely influence the prognosis of critically ill patients. However, its impact on the outcomes of patients with cirrhosis and acute gastroesophageal variceal bleeding remains unknown. We evaluated adrenal function using short corticotropin stimulation test in patients with cirrhosis and gastroesophageal variceal bleeding. The main outcomes analyzed were 5-day treatment failure and 6-week mortality.

DESIGN

Prospective observational study.

SETTING

Ten-bed gastroenterology-specific medical ICU at a 3,613-bed university teaching hospital in Taiwan.

PATIENTS: Patients with liver cirrhosis and acute gastroesophageal variceal bleeding.

INTERVENTIONS: None.

MEASUREMENTS AND MAIN

RESULTS

We evaluated adrenal function using short corticotropin stimulation test in 157 episodes of gastroesophageal variceal bleeding in 143 patients with cirrhosis. Critical illness-related corticosteroid insufficiency occurred in 29.9% of patients. The patients with critical illness-related corticosteroid insufficiency had higher rates of treatment failure and 6-week mortality (63.8% vs 10.9%, 42.6% vs 6.4%, respectively; p < 0.001). The cumulative rates of survival at 6 weeks were 57.4% and 93.6% for the critical illness-related corticosteroid insufficiency group and normal adrenal function group, respectively (p < 0.001). The cortisol response to corticotropin was inversely correlated with Model for End-Stage Liver Disease and Child-Pugh scores and positively correlated with the levels of high-density lipoprotein and total cholesterol. Hypovolemic shock, high-density lipoprotein, platelet count, and bacterial infection at inclusion are independent factors predicting critical illness-related corticosteroid insufficiency, whereas critical illness-related corticosteroid insufficiency, Model for End-Stage Liver Disease score, hypovolemic shock, hepatocellular carcinoma, and active bleeding at endoscopy are independent factors to predict treatment failure. Multivariate analysis also identified Model for End-Stage Liver Disease score, hypovolemic shock, and bacterial infection at inclusion as independent factors associated with 6-week mortality.

CONCLUSIONS

Critical illness-related corticosteroid insufficiency is common in cirrhotic patients with acute gastroesophageal variceal bleeding and is an independent factor to predict 5-day treatment failure.
