Ascites and Chronic Liver Disease in Children.

Development of ascites in children with chronic liver disease is the most common form of decompensation. It is associated with a poor prognosis and increased risk of mortality. A diagnostic paracentesis should be performed in liver disease patients with- new-onset ascites, at the beginning of each hospital admission and when ascitic fluid infection (AFI) is suspected. The routine analysis includes cell count with differential, bacterial culture, ascitic fluid total protein and albumin. A serum albumin-ascitic fluid albumin gradient of ≥1.1 g/dL confirms the diagnosis of portal hypertension. Ascites has been reported in children with non-cirrhotic liver disease like acute viral hepatitis, acute liver failure and extrahepatic portal venous obstruction. The main steps in management of cirrhotic ascites include dietary sodium restriction, diuretics and large-volume paracentesis. Sodium should be restricted to maximum of 2 mEq/kg/d (max 90 mEq/d) of sodium/day. Oral diuretic therapy comprises of aldosterone antagonists (e.g., spironolactone) with or without loop-diuretics (e.g., furosemide). Once the ascites is mobilized, the diuretics should be gradually tapered to the minimum effective dosage. Tense ascites should be managed with a large-volume paracentesis (LVP) preferably with albumin infusion. Therapeutic options for refractory ascites include recurrent LVP, transjugular intrahepatic porto-systemic shunt and liver transplantation. AFI (fluid neutrophil count ≥250/mm) is an important complication, and requires prompt antibiotic therapy. Hyponatremia, acute kidney injury, hepatic hydrothorax and hernias are the other complications.
