The development of cloudy peritoneal dialysis effluent is of great concern to the patient undergoing therapy with Continuous Ambulatory Peritoneal Dialysis. As described in this study, not all cloudy fluid represents bacterial infection. We describe the occurrence of cloudy fluid in eight patients in whom culture of the dialysate did not yield any growth, and whose cell count was characterized by the presence of significant numbers of the eosinophiles. As outlined, the entity of eosinophilic peritonitis has a characteristic presentation which allows for its distinction from the more common bacterial peritonitis.
