Maintenance dialysis in North American children and adolescents: a preliminary report. North American Pediatric Renal Transplant Cooperative Study (NAPRTCS).

During 1992 the North American Pediatric Renal Transplant Cooperative Study (NAPRTCS) began to develop a pediatric Dialysis Patient Data Base by collecting data on pediatric patients who had received either hemodialysis (HD) or peritoneal dialysis (PD), or both, at a participating NAPRTCS center. This preliminary report describes study methods and contains detailed, though short-term observations reported by 64 of 87 NAPRTCS centers on 762 patients who were < 21 years of age at enrollment and who received treatment between January 1, 1992 and September 15, 1992. In these 762 patients, a total of 810 independent courses of dialysis therapy were identified (PD = 534 [65.9%]; HD = 276 [34.1%]). Patients age groupings showed a significantly greater proportion of PD patients among younger age groups. Automated peritoneal dialysis was used by about 75% of registered PD patients at one and six months after registration. A total of 196 peritonitis episodes were reported, yielding a peritonitis rate of one episode every 7.1 patient-months. Ten percent of PD catheters were replaced, primarily for mechanical malfunction and leaks. Percutaneous catheters were used for vascular access in about one-half of the HD patients, with the remainder almost equally divided between arteriovenous fistulae and grafts. Vascular access revision was reported in 28% of HD patients, with about one-third of these revisions performed to create a more permanent access. Recombinant human erythropoietin therapy was used in 89% of PD and 94% of HD patients at six months. Recombinant human growth hormone therapy was used in 9% of PD and 5% of HD patients at six months.(ABSTRACT TRUNCATED AT 250 WORDS)
