[Clinical and microbiological aspects of peritonitis associated with peritoneal dialysis in adult patients with chronic renal failure in the Emergency Department].

BACKGROUND
Peritonitis is the most important and frequent complication of peritoneal dialysis (PD). Bacterial infections are responsible in most cases, with characteristic symptoms.


AIM
To determine the most frequent pathogens in peritonitis associated with PD in patients with chronic renal failure (CRF). Methodos: Retrospective, descriptive, cross-sectional and observational study of patients with peritonitis in PD with CRF of the emergency department, between July 2012 and June 2013. Sociodemographic, diagnostic, clinical and microbiological and cellular data were evaluated from the patient's fluid. Dialysis.


RESULTS
From 73 reviewed records, 52% were male. The primary cause of CRF was diabetes mellitus type 2 (67%). Symptoms presented: abdominal pain (86%), vomiting (42%) and nausea (34%), with anemia, azotemia, hyperglycemia, hypoalbuminemia and hyponatremia. The positive microbiological cultures were 59%; and the pathogens identified were Candida tropicalis (9.6%), Staphylococcus epidermidis (8.2%), Enterococcus faecalis and Staphylococcus haemolyticus (6.8% each one), associated with elevated leukocytes, azotemia and high cellularity in peritoneal fluid (p <0.05).


CONCLUSIONS
The main microorganism determined was of fungal origin associated with leukocytes, azotemia and high cellularity.
