    Abstract:
    Peritonitis, the major complication of peritoneal dialysis (PD), is associated with high morbidity and mortality. It is a major cause of hospitalization and transfer to hemodialysis. In the present study, we aimed to identify predictors of hospitalization in PD-related peritonitis and to examine its microbiology profile over time in our unit to determine the best therapeutic approach. We studied all peritonitis episodes that occurred in a 6-year period (January 1, 2004, to December 31, 2009), evaluating whether adequate treatment could be delivered on an outpatient basis. During the study period, 411 patients were on PD, and 229 peritonitis episodes were recorded in 91 patients. Peritonitis were treated according to unit protocol. The average hospital stay was 11.6 +/- 6.6 days. We observed an increase of Streptococcus (to 19.4% from 7.7%) and a stabilization of coagulase-negative Staphylococcus, S. epidermidis, and S. aureus (from 9.5%, 22.6%, and 3.2% to 7.7%, 30.8%, and 3.8% respectively) peritonitis episodes. The main risk factors for hospitalization were fungal infection, poor 72-hour outcome, inability to perform self-care, and age greater than 80 years. We observed a decline in the incidence of peritonitis, and despite changes in its microbiology profile, no loss of sensitivity to antibiotics used was observed.
