There are indications that advanced glycosylation end-products (AGEs) may affect in some manner the functions of the peritoneum. Only a few reports discuss the actual generation of glycosylated proteins and the intraperitoneal kinetics involved during continuous ambulatory peritoneal dialysis (CAPD). To demonstrate the formation of AGEs and their time-courses in peritoneal dialysis (PD) effluents, measurements were made of furosine, carboxymethyl lysine (CML), and pentosidine as glycosylation markers in vitro and in vivo using PD effluents obtained every 2 hours for up to 8 hours from 3 nondiabetic CAPD patients. Furosine and CML were found to be generated relatively early (within 6 hours), and their de novo formation was markedly enhanced subsequent to glucose addition. Furosine and CML production increased in proportion to glucose concentration. Pentosidine production did not change with time for up to 24 hours, and was not induced by glucose during this period. Carboxymethyl lysine production appeared to be suppressed in vitro with the addition of serum protein. Furosine in the intraperitoneal dialysate was initially the same as that in the plasma, but increased to twice as much in just 2 hours in vivo. Production of CML increased, but apparently was suppressed with leakage of plasma protein into the dialysate; this possibly may have been due to dilutional or antiglycation effects in the plasma. No stimulation of pentosidine production could be detected in the intraperitoneal dialysate even at 8 hours. The initiation of glycosylation of peritoneal proteins, with generation of furosine and CML but not pentosidine, is clearly shown by the present results to occur relatively early in the intraperitoneal dialysate, i.e., within a matter of hours.
