Drawing upon data from a large European study, Andrés Cárdenas, MD, reported an association between hyponatremia and acute-on-chronic liver failure (ACLF) during a poster session at the 2013 annual meeting of the American Association for the Study of Liver Diseases held November 1-5, 2013, in Washington, DC.
Cirrhosis patients who experience ACLF may face poor short-term survival. The condition is characterized by a systemic inflammatory response, with acute decompensation and organ failure.
For their poster, Cárdenas and colleagues from the Institute of Digestive Diseases and Metabolism at the Hospital Clinic and University of Barcelona examined data from the CLIF Acute-on-Chronic Liver Failure in Cirrhosis Study (CANONIC) to determine whether hyponatremia has prognostic value in cirrhotic patients with and without ACLF.
The CLIF CANONIC database included the health records of 1,341 consecutive patients at 29 different European centers who presented with acute decompensation of cirrhosis of the liver.
Of the 517 patients with acute compensation of cirrhosis available for the study’s 28-day follow-up period, 217 (42.0%) had ACLF at enrollment, while 300 (58.0%) were free of ACLF when they enrolled. Of the group with ACLF, 48 (22.1%) had hyponatremia, which was defined as serum sodium <130meq/L. No hyponatremia was seen in 179 (78.9%) of the ACLF patients.
