Relative adrenal insufficiency in cirrhotic patients with ascites (hepatoadrenal syndrome).

AIM

Relative adrenal insufficiency (RAI) has been reported in critically ill patients with cirrhosis. We evaluated the prevalence of RAI and its relationship to clinical course in non-septic cirrhosis patients with ascites.

METHODS

The study included 66 consecutive non-septic cirrhosis patients with ascites. RAI was defined by a delta cortisol lower than 9 μg/dL and/or a peak cortisol lower than 18 μg/dL.

RESULTS

Sixty-six patients with cirrhosis and ascites were studied. The mean Child-Turcotte-Pugh (CTP) and model for end stage liver disease (MELD) scores were 10.6 ± 1.9 and 21.5 ± 7.3, respectively. The prevalence of RAI in patients with cirrhosis and ascites was 47% (31/66). The prevalence of RAI in patients with and without spontaneous bacterial peritonitis, renal failure and type 1 hepatorenal syndrome (HRS) was comparable. Baseline hyponatremia was common in RAI (42% versus 17%, p = 0.026). There was a significant correlation of prevalence of RAI with prothrombin time, international normalized ratio, MELD scores and CTP class. During follow-up, there was no association between RAI and the risk to develop new infections, severe sepsis, type 1 HRS and death.

CONCLUSIONS

RAI is common in non-septic cirrhotic patients with ascites and its prevalence increases with severity of liver disease. However, it does not affect the short-term outcome in these patients.
