AIM:The aim of this work was to assess the frequency of spontaneous bacterial empyema in cirrhotic patients with ascites and determine the possible associated risk factors of spontaneous bacterial empyema in those patients. MATERIALS AND METHODS: 322 cirrhotic patients with ascites and pleural effusion were enrolled. Spontaneous bacterial empyema was diagnosed by positive pleural fluid culture or, if negative, a pleural fluid PMNL count >500 cells/mm3 without radiographic evidence of pneumonia or a contiguous infection process on chest radiography. RESULTS: The frequency of spontaneous bacterial empyema (SBEM) among cirrhotic patients with ascites and hepatic hydrothorax was 14.3% (46 out of 322 cirrhotic patients). E.Coli was the commonest organism (54.8%) responsible for SBEM in positive culture cases. CONCLUSION: SBEM was recognized in 14.3% of cirrhotic patients with ascites and hepatic hydrothorax. So, it is a frequent but underdiagnosed complication of hepatic hydrothorax and has a poor prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
