Background: Bacterial infections in end stage liver disease are common and associated with increased mortality. Although extensive research has elucidated the impact of bacterial infections as the major precipitating event leads to increased frequency of liver-related complications and mortality in these patients. Objective: Evaluating the clinical and laboratory characters, risk factors, and outcome of fungal and bacterial peritonitis in cirrhotic patients with end stage liver disease (ESLD). Patients and Methods: This cross sctional study enrolled 60 patients with liver cirrhosis and ascites. Fifty patients were culture-positive spontaneous peritonitis, including 12 with spontaneous fungal peritonitis (SFP), and 38 culture-positive spontaneous bacterial peritonitis (SBP), and 10 patients without clinical or laboratory evidence of peritonitis as a control group, during the study period, between 1st February 2018 and 30th May 2019. We compared the clinical, laboratory findings, Child–Pugh scores, model for end stage liver disease (MELD) score, risk factors, and mortality rates between patients with spontaneous peritonitis associated with fungal culture-positive ascites, and those with spontaneous peritonitis associated with bacterial culture-positive ascites. Results: Patients of the current study were critically ill. The mean duration of ESLD in the studied patients was 4.75 ± 1.8 year, 57 patients (95.0%) were Child score C, and 3 patients (5%) were Child score B. The mean MELD score was 23.32 ± 5.49. All patients with evidence of peritonitis were Child C, and mean MELD scores were 22.6 ±5.7 and 26.1±4.5 in SBP and SFP groups respectively. Jaundice, GI bleeding and hepatic encephalopathy were significantly for clinical presentation and predictors of mortality in SFP group compared to SBP and control group. Lower levels of hemoglobin (Hb), S. albumin and platelets count and increased level of total leukocytic count (TLC), international normalized ratio (INR), and bilirubin were significantly higher in SFP group compared to SBP and control group.       Duration of ESLD and hospital admission was significant in SFP compared to SBP and control group. HCC was evident in SFP group (66.7%) that was highly significant in comparison to SBP (28.9%), and control group (20%). Overall mortality rate among the studied groups was 45%, the mortality rate was significantly increased in SFP group (75%) compared to SBP (42.1%), and control group (20%).The mean MELD score significantly increased in non-survival group compared to survival group . The duration of ESLD significantly increased in non-survival group compared to survival group. Conclusion: Prolonged and severe underlying liver disease with a high Child- Pugh or MELD score, renal impairment, HCC, and onset of severe sepsis have been reported as risk factors in increased mortality in patients with SFP than in SBP.  In SFP, mortality was associated not only with the severity of the underlying liver disease, but also with delay in diagnosis and initiation of antifungal therapy.
