Background: Peritoneal dialysis (PD) is the preferred chronic dialysis modality amongst pediatric patients. Peritonitis is a devastating complication of PD. Adult data demonstrates early onset peritonitis (EP) is associated with higher rates of subsequent peritonitis and technique failure. Limited data exists regarding EP in the pediatric population, here defined as peritonitis occurring within 60 days of catheter insertion., Methods: PD catheter insertion practices and EP episodes were examined from the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) collaborative database., Results: There were 98 episodes of EP amongst 1106 PD catheters inserted. Multivariable analysis demonstrated a significant association between early use of the PD catheter and EP (P = 0.001). Age less than 1 year at the time of catheter insertion (P < 0.001), first catheter placed (P < 0.001) for the patient, use of a plastic adapter (P = 0.003), placement of sutures at the exit site (ES) (P = 0.032), and dressing change prior to 7 days post-operatively (P < 0.001) were all significantly associated with early PD catheter use. Concurrent placement of a hemodialysis catheter was associated with a decreased risk for early PD catheter use (P = 0.010)., Conclusions: In this large cohort of pediatric PD recipients, 8.4% of PD catheters were associated with the development of EP. The finding of an association between early use of the PD catheter and EP represents a potentially modifiable risk factor to reduce infection rates within this patient population.

Short-term renal allograft survival in children has improved. It is therefore important to determine the factors leading to long-term graft function. To this end, we evaluated patients in the NAPTRCS registry who were <12 years old when they received their renal transplant between 1987 and 1993. Children with 10 years of post-transplant follow-up were compared to those in whom the transplant failed within 10 years. Children with a failed transplant within 10 years of the surgery tended to be older, female, and non-Caucasian; they also manifested obstructive uropathy less often and had focal segmental glomerulosclerosis more often, and they received more deceased donor kidneys. Children with a failed renal transplant had fewer HLA donor and recipient matches, received pre-transplant dialysis compared to a preemptive transplant, required dialysis in the first week post-transplant, and required more antihypertensives the first month post-transplant. Allograft function was examined at 10 years. Patients with continued allograft function and a serum creatinine

Acute renal failure requiring renal replacement therapy can complicate cardiopulmonary bypass in children. Peritoneal dialysis has been shown to stabilize electrolytes and improve fluid status in these patients. To assess dialysis adequacy in this setting, we prospectively measured Kt/V and creatinine clearance in five patients (6-839 days of age) requiring renal replacement therapy at our institution. Median dialysis creatinine clearance was 74.25 L/week/1.73m(2) (range 28.28-96.63 L/week/1.73m(2)). Residual renal function provided additional solute clearance as total creatinine clearance was 215.97 L/week/1.73m(2) (range 108.04-323.25 L/week/1.73m(2)). Dialysis Kt/V of >2.1 (median 4.84 [range 2.12-5.59]) was achieved in all patients. No dialysis-associated complications were observed. We conclude that peritoneal dialysis is a safe, simple method of providing adequate clearance in children who develop acute renal failure following exposure to cardiopulmonary bypass.

Hyperphosphatemia has been associated with the development of secondary hyperparathyroidism, renal osteodystrophy, cardiovascular calcification and increased risk of death. Using a one group, pretest-posttest study design, we sought to evaluate changes in serum phosphorus, calcium, parathyroid hormone and subject knowledge in response to a 3-month educational intervention. Mean serum phosphorus levels did not differ significantly between the three evaluation periods: pretreatment (5.69 mg/dl), treatment (5.84 mg/dl) and posttreatment (6.17 mg/dl). Mean serum calcium, calcium-phosphorus product and PTH values also did not differ significantly between the treatment periods. We observed no difference between the subject test scores between the two testing periods. Calcium-phosphorus product, serum phosphorus and PTH values on average, despite the education program, remained outside the K/DOQI target guidelines 44, 56 and 81% of the time, respectively. The results of this study suggest that an aggressive 3-month patient education program targeting dietary phosphorus knowledge, phosphate binder name and dosing, and knowledge of medical consequences associated with non-compliance had no effect on the serum phosphorus, calcium, PTH or phosphate binder need.
