Opsonically-Active Proteins in CAPD Fluid
Concentrations of albumin, transferrin, IgG, C3 and α 2 macroglobulin were measured by radial immunodiffusion in serum and dialysate of patients treated by CAPD. Fibronectin and CH50 were also measured by nephelometry and dialysate opsonic activity was determined. Transport of proteins into peritoneal dialysate was low, varied considerably from patient to patient, and showed little discrimination according to protein size. The dialysate protein level correlated with in vitro opsonic activity.
