title: Ascites in childhood liver disease.
abstract: Ascites is a common clinical problem in children with liver disease. The peripheral arterial vasodilation hypothesis is mostly accepted as the pathophysiological basis of ascites. The most important complication is spontaneous ascitic fluid infection in the form of spontaneous bacterial peritonitis (SBP) and its variants. Aerobic gram-negative bacteria, primarily Escherichia coli, are the most common isolates. Diagnostic paracentesis is done in patients with ascites when diagnosed first time and at the beginning of each admission to hospital. Ascitic fluid is evaluated for cell count with differential, albumin level, total protein and culture. Serum-ascites albumin gradient (SAAG) is the best single test for classifying ascites into portal hypertensive (SAAG> 1.1 g/dL) and non-portal hypertensive (SAAG < 1.1 g/dL) causes. In patients with tense ascites LVP should be performed. A neutrophil count of > 250 cells/mm3 is highly suggestive of bacterial peritonitis. Intravenous cefotaxime is the empiric antibiotic of choice. Long-term administration of oral norfloxacin 5-7.5 mg/Kg once a day in cirrhotic patients with ascitic fluid protein content of < 1g/dL or prior episode of SBP is recommended for prevention of SBP. Oral dual diuretic therapy of single morning dose of spironolactone along with furosemide in the ratio of 5:2 is recommended. While obtaining satisfactory diuretic response dual diuretic therapy can be changed over to monotherapy with spironolactone. Patients should be on sodium restricted diet. Management of ascites might ultimately require liver transplantation.
