| Popis: | To investigate differences in the transport characteristics of the peritoneal membrane between diabetic and non-diabetic patients on chronic peritoneal dialysis, a study was conducted in 21 non-diabetic and 18 diabetic patients. Transperitoneal transport of small solutes was evaluated in terms of the mass transfer area coefficients (urea, creatinine and glucose), ultra-filtration sieving coefficients (urea and creatinine) and by peritoneal equilibration test results. The capacity of the peritoneal membrane to transport macromolecules was evaluated by albumin mass transfer rates and clearances of albumin. Transperitoneal water transport was evaluated by the ultra-filtration properties and the lymphatic flow rates. Finally, the whole-body capillary permeability was estimated by measuring the unidirectional flux of albumin across the capillary wall, i.e. the transcapillary escape rate of 125I-labelled human albumin. Despite a significantly increased transcapillary escape rate of albumin in the diabetic patients, no differences in peritoneal membrane characteristics could be demonstrated between diabetic and non-diabetic patients on peritoneal dialysis. |
