Objective: Although presence of ascites has been reported in patients with fulminant hepatic failure (FHF), spontaneous bacterial peritonitis (SBP) has not been studied in a large group of such patients. Hence, the present study was conducted to evaluate the prevalence and prognostic significance of ascites and SBP in FHF patients.
Methods: Two hundred ninety-eight consecutive patients (mean age 32.9+/-14.8 yr) with FHF were studied. There were 133 (44.6%) men and 165 (55.4%) women. Acute viral hepatitis accounted for 91.6% of the patients and were analyzed in the present study.
Results: Ascites was clinically detected in 79 (28.9%) patients. The patients with ascites were older (p = 0.005), had longer jaundice-encephalopathy interval (p<0.0000001), lesser grade of encephalopathy on admission (p = 0.0000043), and a lower incidence of raised intracranial pressure on admission (p = 0.0007). Patients with ascites had significantly lower serum albumin (p = 0.021), ALT (p = 0.0005), AST (p = 0.00017), and PT (p = 0.002) on admission than in patients without ascites. Multivariate logistic regression analysis showed that jaundice-encephalopathy interval (> or =14 days) and serum albumin (< or =2.5 g/dl) were the only independent predictors of ascites. SBP was detected in 14 (17.7%) patients (neutrocytic culture positive, 4; neutrocytic culture negative, 9; and monomicrobial bacterascites, 1). Escherichia coli was identified in three patients. Survival was no different between patients with and those without ascites and also between patients with and those without SBP.
Conclusions: Ascites is a frequent accompaniment of FHF and is complicated by SBP. Jaundice-encephalopathy interval of 14 days or more and serum albumin (< or =2.5 g/dl) on admission predicts the development of ascites in these patients.
