Looks are deceiving: An uncommon cause of milky white peritoneal dialysis effluent

Peritoneal dialysis effluent should be clear and any changes in aspect require further investigation. We report a case of a spontaneous milky white effluent (chyloperitoneum) associated with calcium channel blockers in a peritoneal dialysis patient. Our case is a 43-year-old man that presents with milky white peritoneal dialysis effluent 9 days after starting peritoneal dialysis. He didn't have any other complaints and he wasn't prescribed any new medications. In the effluent sample we found high triglycerides (1.8 mmol/L) thus confirming the chyloperitoneum. We suspended lercanidipine and within a few days the peritoneal dialysis effluent was clear. Currently the patient is well adjusted to the technique and had no further episodes of chyloperitoneum.
