Association between peritoneal dialysate effluent leukocytosis and amlodipine besylate.

Dialysate effluent leukocytosis is consistent with a greater degree of infection or inflammation in patients receiving peritoneal dialysis. This study describes a girl aged 2 years 9 months with end-stage renal disease resulting from crescent glomerulonephritis and severe interstitial nephritis who developed leukocytosis with a predominance of lymphocytes in the dialysate effluent, and in whom the effluent cell count normalized 1 week after discontinuation of amlodipine besylate therapy. Rechallenge confirmed that amlodipine was the offending agent causing effluent leukocytosis.
