Portal pressure in patients with exudative ascites in the course of acute hepatitis B

Abstract

We describe three patients who developed ascites during the course of acute viral hepatitis B. Two of them had exudative ascites, with a high protein and cell content, and the other transudative ascites, with low protein and cell content. Both patients with exudative ascites had a benign clinical course, and their liver disease was milder than in the patient with transudative ascites, who had signs of severe liver failure and a submassive hepatic necrosis on liver biopsy. Moreover, the patient with transudative ascites had evidence of portal hypertension (as indicated by a hepatic vein pressure gradient of 12.5 mmHg, normal 1-6 mmHg), whereas patients with exudative ascites did not (hepatic vein pressure gradient of 5 and 5.5 mmHg, respectively). These data support our previous suggestion that "exudative" ascites during acute viral hepatitis B represents a self-limited immunopathetic sign that is not related to portal hypertension or severe hepatic disease.
