Abstract

Nitric oxide (NO) is a molecule involved in vascular dilatation and pathogen suppression. It also has immunologic and regulatory functions. Liver cirrhosis is characterized by an increased risk for bacterial infections, including spontaneous bacterial peritonitis (SBP). The role of NO in SBP which develops in cirrhosis has not been clearly established. The aim of this study was to investigate the role of NO in the pathogenesis of SBP and its clinical usefulness for prediction of disease prognosis. This study was designed to investigate the changes of ascites NO in the course of treatment. Nitric oxide metabolite (nitrites+nitrates [NOx]) was measured by chemiluminescence in 84 ascites samples obtained from 84 cirrhotic patients. Among them, the 38 patients with SBP were treated with cefotaxime 2.0 g, q 12hr for 7 days. In 24 of SBP patients, ascites was obtained consecutively before treatment (day 0), during treatment (day 2), and after treatment (day 7). Ascites NO levels in the patients with SBP (n=38; 82.3 +/- 14.4 microM) were not different from those in patients with sterile ascites (n=46; 54.6 +/- 13.0 microM). There was no significant change of NO levels in sequential ascites samples during antibiotic treatment. Ascites ...Continue Reading
