Abstract
BACKGROUND AND AIMS: Acute on chronic liver failure (ACLF) is an emerging entity whose unique pathogenesis, presentation, and outcome are different from those with decompensated cirrhosis. Patients with Wilson disease (WD) often present with ACLF. The outcome in this setting and predictors of mortality have not been well delineated. We describe the clinical features, laboratory characteristics, and prognostic factors in patients with WD with ACLF. We compared the outcome in those without criteria for ACLF. PATIENTS AND METHODS: We analyzed the admission characteristics of 68 patients with WD presenting with features of ACLF among a cohort of WD patients from 1997 to 2017. WD was diagnosed as per European association for the study of the liver (EASL)/Leipzig criteria and ACLF by the Asia-Pacific Association of Study of Liver and World Gastroenterology Organization consensus criteria. Factors associated with mortality were analyzed by univariate followed by multivariate analysis and receiver operating characteristic curve. RESULTS: Of the 272 patients with WD, 68 fulfilled criteria for ACLF. The mean age was 14.4 years (Range 5-42 years). Males constituted 38/68 (56%). Acute viral or drug induced hepatitis as precipitating factors was seen in 11.7%. Forty-nine patients (49/67; 73%) died including 30/32 (93.8%) with encephalopathy and 45/62 (72.6%) with ascites. Prognostic factors on univariate analysis significant for mortality included encephalopathy, international normalized ratio, white blood cell count and model for end-stage liver disease (MELD) score. On multivariate analysis, only encephalopathy was significant with 82% accuracy in differentiating survivors versus non-survivors. Post mortem liver biopsy in 21 patients and explant biopsy in 2 patients showed features of cirrhosis in all. CONCLUSIONS: WD with ACLF is associated with a high mortality Precipitating factors such as viral and drug-induced hepatitis was seen in 11.7% patients. Liver histology in patients subjected to biopsy showed cirrhosis in all. Only encephalopathy is a prognostic marker of non-survival with an accuracy of 82%.
