Spontaneous bacterial empyema (SBEM) is an infection of a preexisting hydrothorax in cirrhotic patients and has seldom been reported. To determine its incidence and primary characteristics, all cirrhotic patients with pleural effusion underwent thoracentesis at our hospital either on admission or when an infection was suspected. Pleural fluid (PF) study included biochemical analysis, polymorphonuclear (PMN) leukocyte count, and culture by two methods: conventional and modified (inoculation of 10 mL of PF into a blood culture bottle at the bedside). SBEM was defined according to previously reported criteria: PF culture positive or PMN count greater than 500 cells/micro L, and exclusion of parapneumonic effusions. Sixteen of the 120 (13 percent) cirrhotic patients admitted with hydrothorax had 24 episodes of SBEM. In 10 of the 24 episodes (43 percent), SBEM was not associated with spontaneous bacterial peritonitis (SBP). PF culture was positive by the conventional method in 8 episodes (33 percent) and by the modified method (blood culture inoculation) in 18 (75 percent) (P = .004, McNemar). The microorganisms identified in PF were Escherichia coli in 8 episodes, Streptococcus species in 4, Enterococcus species in 3, Klebsiella pneumoniae in 2, and Pseudomonas stutzeri in 1. All episodes were treated with antibiotics without inserting a chest tube in any case. Mortality during treatment was 20 percent. We conclude that SBEM is a common complication of cirrhotic patients with hydrothorax. Almost half of the episodes were not associated with SBP; thus, thoracentesis should be performed in patients with cirrhosis, pleural effusion, and suspected infection. Culture of PF should be performed by inoculating 10 mL into a blood culture bottle at the bedside.

ABSTRACT: Hepatic hydrothorax is defined as a significant pleural effusion in patients with liver cirrhosis and without underlying cardiopulmonary diseases. Treatment of hepatic hydrothorax remains a challenge at present.
Herein we share our experiences in the treatment of 12 patients with hepatic hydrothorax by video-assisted thoracoscopic surgery (VATS). Repair of the diaphragmatic defects, or pleurodesis by focal pleurectomy, talc spray, mechanical abrasion, electro-cauterization or injection was administered intraoperatively, and tetracycline intrapleural injection was used postoperatively for patients with prolonged (>7 d) high-output (>300 ml/d) pleural effusion.
Out of the 12 patients, 8 (67%) had uneventful postoperative course and did not require tube for drainage more than 3 months after discharge. In 4 (33%) patients the pleural effusion still recurred after discharge due to end-stage cirrhosis with massive ascites.
We conclude that the repair of the diaphragmatic defect and pleurodesis through VATS could be an alternative of transjugular intrahepatic portal systemic shunt (TIPS) or a bridge to liver transplantation for patients with refractory hepatic hydrothorax. Pleurodesis with electrocauterization can be an alternative therapy if talc is unavailable.

- "Another manifestation of the bacteremia resulting from the bacterial translocation is spontaneous bacterial empyema (SBEM). Xiol et al. reported that most episodes of SBEM in cirrhotics was not associated with SBP (11), suggesting that infected ascites diffusing across the diaphragm is not the mechanism involved and supporting the possibility of bacterial translocation. The bacteremia seen in cirrhotics may also be responsible for the increased incidence of bacterial endocarditis (12). "

ABSTRACT: Despite septic arthritis is increasingly being reported in elderly patients with diabetes or alcoholism, reported cases of spontaneous bacterial arthritis in cirrhotic patients are extremely rare. We present the first reported case of K. pneumoniae septic arthritis and spontaneous bacterial peritonitis in a cirrhotic patient with hepatocellular carcinoma. K. pneumoniae, one of the most common causative organisms of spontaneous bacterial peritonitis in cirrhotic patients, was isolated from both the blood and the joint fluid, which suggests that the route of infection was hematogenous. After the treatment with cefotaxime and closed tube drainage, the condition of the patient was improved, and subsequently, the joint fluid became sterile and the blood cultures were proved negative. Therefore, this case provides further evidence for the mode of infection being bacteremia in cirrhotic patients and suggests that the enteric bacteremia in cirrhotics may cause infection in different organ systems.

- "Xiol et al. proposed a diagnostic criteria for spontaneous bacterial empyema (Xiol et al., 1996): (1) clinical evidence of fever or shock; (2) positive pleural fluid culture or, if negative, a pleural fluid neutrophil count greater than 500 cells/mm 3 ; (3) no evidence of pneumonia on chest radiology; and (4) preexisted hepatic hydrothorax. When all the above criteria were fulfilled, the diagnosis of spontaneous bacterial empyema was established. "

ABSTRACT: Spontaneous bacterial empyema is a complication of hepatic hydrothorax in cirrhotic patients. The pathogen, clinical course and treatment strategy are different to the empyema secondary to pneumonia. A 54-year-old man, who was a cirrhotic patient with hepatic hydrothorax, was admitted to National Taiwan University Hospital for fever, dyspnea and right side pleuritic pain. The image study revealed massive right pleural effusion and no evidence of pneumonia. The culture of pleural effusion yielded Aeromonas veronii biotype sobria. The diagnosis of spontaneous bacterial empyema caused by Aeromonas veronii biotype sobria was established. To our best knowledge, Aeromonas veronii biotype sobria had never been reported in English literature as the causative pathogen of spontaneous bacterial empyema.
