BACKGROUND Spontaneous peritonitis is one of the most common infectious complications in cirrhotic patients with ascites.Spontaneous fungal peritonitis (SFP) is a type of spontaneous peritonitis that is a less recognized but devastating complication in end-stage cirrhosis.Although high mortality was previously noted,scant data are available to fully define the factors responsible for the occurrence of SFP and its mortality.AIM To illustrate the differences between SFP and spontaneous bacterial peritonitis (SBP) and discuss the risk factors for the occurrence of SFP and its short-term mortality.METHODS We performed a matched case-control study between January 1,2007 and December 30,2018.Patients with SFP were included in a case group.Sex-,age-,and time-matched patients with SBP were included in a control group and were further divided into control-1 group (positive bacterial culture) and control-2 group (negative bacterial culture).The clinical features and laboratory parameters,severity models,and prognosis were compared between the case and control groups.Logistic regression analysis was used to determine the risk factors for occurrence,and the Cox regression model was used to identify the predictive factors for short-term mortality of SFP.RESULTS Patients with SFP exhibited more severe systemic inflammation,higher ascites albumin and polymorphonuclear neutrophils,and a worsened 15-d mortality than patients in the control groups.Antibiotic administration (case vs control-1: OR = 1.063,95%CI: 1.012-1.115,P = 0.014;case vs control-2: OR = 1.054,95%CI: 1.014-1.095,P = 0.008) remarkably increased the occurrence of SFP or fungiascites.Hepatorenal syndrome (HR = 5.328,95%CI: 1.050-18.900) and total bilirubin (μmol/L;HR = 1.005,95%CI: 1.002-1.008) represented independent predictors of SFP-related early mortality.CONCLUSION Long-term antibiotic administration increases the incidence of SFP,and hepatorenal syndrome and total bilirubin are closely related to short-term mortality.

Patients with SFP were included in a case group. Sex-, age-,and time-matched patients with SBP were included in a control group and were further divided into control-1 group(positive bacterial culture) and control-2 group(negative bacterial culture). The clinical features and laboratory parameters, severity models, and prognosis were compared between the case and control groups. Logistic regression analysis was used to determine the risk factors for occurrence, and the Cox regression model was used to identify the predictive factors for short-term mortality of SFP.RESULTS Patients with SFP exhibited more severe systemic inflammation, higher ascites albumin and polymorphonuclear neutrophils, and a worsened 15-d mortality than patients in the control groups.
