Clinical significance of untreated Candida species isolated from ascites in cirrhotic patients.

The clinical significance of Candida species isolated from cirrhotic ascites is still unknown. We reviewed the clinical and laboratory features of all cirrhotic patients whose ascites samples were positive for Candida species. A total of 21 cirrhotic patients was identified. Patients were regarded as having peritonitis if they had 1 or more clinical symptom(s) or sign(s) in the absence of any other possible explanation. 10 patients (47.6%) were classified into the spontaneous Candida peritonitis (SCP) group, and the remaining 11 patients (52.4%) were classified into asymptomatic candidascites. Mortalities were higher in the SCP group at discharge (50.0% vs 27.3%), 6-month (90% vs 45.5%) and 1-y (100% vs 54.5%) (p=0.007). Receiver-operating characteristic curve analysis revealed that the cut-off value of ascitic fluid polymorphonuclear cell count of 315/mm(3) (0.315 x 10(9)/l) had the highest diagnostic accuracy with both sensitivity and specificity of 1.0. In conclusion, Candida species are associated with a grave outcome when manifested with peritonitis.
