Fungal Peritonitis in Peritoneal Dialysis: Risk Factors and Prognosis

Abstract

Although less common than bacterial peritonitis, fungal peritonitis is associated with much higher morbidity and mortality. In this study, we aimed to determine the risk factors for fungal peritonitis in peritoneal dialysis patients. The records of 109 peritoneal dialysis patients were analyzed. A total of 86 episodes of peritonitis attacks were recorded. Nine (10.5%) of these attacks were fungal peritonitis attacks. The fungal peritonitis attack rate of the population was 1 attack per 480.1 patient months. In order to determine predisposing factors for fungal peritonitis patients, patients with bacterial peritonitis and with no peritonitis admitted immediately before and after those with fungal peritonitis were used as controls. There was no statistically significant difference between the bacterial and fungal peritonitis groups with respect to symptoms and signs. Obligatory peritoneal dialysis treatment due to access or other medical problems (p = 0.04) and serum albumin levels (p = 0.01) were found to be significantly related with fungal peritonitis (p = 0.04). The mortality rate was 11.1%. When compared with the mortality rate of bacterial peritonitis (1.8%) during the same period, it was found to be significantly higher (p = 0.0001). The catheter removal was performed within 2-7 days (mean = 5.2 days) of the fungal peritonitis attacks. In conclusion, we decided that because fungal peritonitis attacks end up with high morbidity and mortality, prompt diagnosis and removal of the catheter is mandatory. Diagnosis highly depends on culture results, as signs and symptoms usually do not differ from that of bacterial peritonitis. Low serum albumin levels and obligatory peritoneal dialysis treatment are found to be the risk factors for fungal peritonitis.
