In 32 patients undergoing continuous ambulatory peritoneal dialysis (CAPD)
and in 56 healthy subjects, ferroxidase I (ceruloplasmin) and ferroxidase II
activity were estimated in serum; in 12 of the 32, it was also measured in
peritoneal fluid. Serum ferroxidase I was normal, while ferroxidase II was
significantly increased. Peritoneal fluid contains appreciable amounts of
ferroxidase I, but no ferroxidase II. The serum ferroxidase profile of
patients on CAPD differs from that of hemodialysis (HD) patients; in the
latter, both ferroxidases are significantly increased. This difference could
be accounted by the loss offerroxidase I in the peritoneal fluid.
KEY WORDS: Serum ferroxidase; ferrox-idase loss in peritoneal fluid.
