One of the main complications associated with Peritoneal Dialysis (PD) is peritonitis of infectious cause (bacterial/fungal), which in many cases is the cause of changing the modality of renal replacement therapy. Within the peritonitis group there is a small percentage of peritonitis that does not respond to infectious causes; it usually has the same clinical presentation with a high cell count in the Peritoneal Fluid (PF) but with a small difference characterized by the significant predominance of eosinophils called Peritonitis. . Eosinophilic (PE).
We present the case of a 58-year-old female patient with a history of CKD stage 5D with admission to hemodialysis in 2018, resolved breast cancer, dilated cardiomyopathy (DCM) and heart failure (HF) with severely depressed ejection fraction (EFY), with poor tolerance to treatment, change of modality to Peritoneal Dialysis (PD) due to positive selection in 2021. In the third month of starting continuous ambulatory peritoneal dialysis (CAPD), the patient experienced intense abdominal pain associated with cloudy fluid, cell count of peritoneal fluid (PF) with increased leukocytes and predominance of eosinophils, culture of peritoneal fluid. in medium enriched with late rescue of Staphylococcus Capitis
Antibiotic treatment with Vancomycin, Amikacin and Nystatin was carried out for 14 days. At the end of the antibiotic regimen and due to persistence of the condition, it was decided to perform oral corticosteroid therapy. A notable improvement was observed 48 hours after starting the treatment with a negative cell count and the presence of clear peritoneal fluid.
The importance of taking this entity into account is that although it has a benign and self-limiting course, in situations of persistent symptoms it may require treatment with corticosteroids, in addition to avoiding the unnecessary use of antibiotic therapy.
