Survival and causes of death in children dialyzed in a single center were analyzed. During the last 12 years a chronic dialysis program was introduced in 146 children in our center and 125 of them, eligible for observation, were included in this analysis; 58 patients were on hemodialysis (HD) and 67 on peritoneal dialysis [continuous ambulatory peritoneal dialysis/automated peritoneal dialysis (CAPD/APD)]. Mean age at the start of dialysis was 13.1 years in HD and 9.8 years in CAPD/APD patients. Overall, 16 patients died (12.5%); 6 (10.3%) on HD and 10 (14.9%) on CAPD/APD; 4 HD patients died of hemorrhagic stroke and 2 were killed in road traffic accidents. Of 10 CAPD/APD patients, 7 died of heart failure, ischemic stroke, and/or disseminated thromboembolic disease. Another was killed in a road traffic accident and 2 died during the course of severe infections. The 1-year patient survival rate was 96.6% in HD patients and 95% in CAPD/APD patients, 2-year survival 94% and 93% and 5-year survival 91% and 78%, respectively (P=0.2, NS). In conclusion, the survival rate for HD and CAPD patients is similar, although after 2 years of therapy, it is lower in CAPD patients. The main causes of death are cardiovascular. However, in CAPD/APD patients, heart failure with low cardiac output and thromboembolic complications are major causes of death, and in HD patients the main cause is hemorrhagic stroke.
IntroductionPeritoneal dialysis (PD) is a preferred method of renal replacement therapy for end-stage renal disease in children. Recent advances have allowed chronic PD to be provided to children of all ages and sizes.Material and methodsThe study was designed as a national (10 dialysis centres), multicentre retrospective analysis of the medical history of 33 children who started chronic peritoneal dialysis in their infancy between 1993 and 2005, with a follow-up period of at least 24 months.ResultsThe nutritional status of the infants was unsatisfactory. The mean SDS of body weight at the start was –2.0, at 1 year of age –1.7. Only 40% of infants were adequately nourished at 1 year of age. Long-term follow-up analysis showed that 12 children received a kidney transplant, 13 were still on dialysis (4 changed method) and 6 died (mortality rate in the first year of life of 9%). In 2 children we observed an improvement of renal function. We observed a relatively high (1/8.8 patient-months) peritonitis rate in the analysed children when compared to 1 : 22 patient-months in all children undergoing PD in Poland.ConclusionsThe results of our survey have shown that the management of dialysed infants is still a challenge for the medical team and families, but long-term results of the therapy are encouraging.
← Objectives Permanent and adequate access to the peritoneal cavity is the key to successful chronic peritoneal dialysis (PD). A variety of catheter designs and implantation techniques have been developed to achieve optimal peritoneal access. One such new and modified PD catheter is the presternal catheter [swan neck presternal catheter (SNPC)], with the exit site located on the chest wall. ← Design A multicenter survey was undertaken to summarize 10 years of experience with the presternal catheter in children in Poland. ← Setting Four pediatric institutions using the SNPC in children: ( 1 ) Medical University of Warsaw, Warsaw; ( 2 ) Childrens’ Memorial Health Institute, Warsaw; ( 3 ) District Children's Hospital, Szczecin; ( 4 ) University of Medical Sciences, Poznan. ← Patients During the past 10 years, 20 presternal catheters were implanted in 19 children, aged 0.2 – 17.7 years (mean 8 ± 5.8 years), with end-stage renal failure. The main indications for the SNPC include urinary diversion (ureterocutaneostomy or vesicostomy), use of diapers, young age, obesity, abdominal wall weakness, and recurrent exit-site infections (ESI) with previous abdominal PD catheters. ← Intervention In all children the presternal catheter was implanted surgically under general anesthesia by one surgeon. Uniform operative technique and uniform perioperative management were used. ← Results The mean observation time for the 20 presternal catheters was 24.8 ± 25 months (range 1 – 83 months). The ESI rate was 1/70.9 patient-months (0.17 episodes per year), tunnel infection rate was 1/248 patient-months (0.05 episodes per year), and the overall peritonitis rate was 1/26.6 patient-months (0.51 episodes per year). Noninfectious complications associated with the SNPC included disconnection of both sections (2 children) and trauma to the exit site located on the chest wall (4 children). Mean survival time of the presternal catheter, as calculated by the Kaplan–Meier method, was 57.5 ± 8.5 months; 50% catheter survival reached 72 months. ← Conclusions The good outcome in patients with a SNPC validates the rationale for the presternal catheter design and should encourage its more widespread use. The SNPC seems to be suitable for any patient on PD; however, this catheter is particularly useful in patients with specific indications ( i.e., higher tendency to ESI). The SNPC allows safe and long-term chronic PD in very young children using diapers and in patients with urinary diversion.
SIOD is rare disorder related to SMARCAL1 or SMARCAL2 gene mutation, including (among other comorbidities) T-cell immunodeficiency, nephrotic syndrome, and renal failure. Up to 22% of primary patients may develop various autoimmune disorders. We report the case of 11-year-old male with SIOD, who presented ITP at 2 years after renal transplantation with decrease in platelet count (from normal) to 56 000/μL and then (gradually) to 2000/μL. There was no effect of iv. methylprednisolone/dexamethasone. As the presence of antibodies against GPIIb/IIIa, GPIb, and GPIaIIa platelet glycoproteins was confirmed, patient was given 50 g of IVIG and then was put on plasmapheresis; however, both showed poor direct effect. As we were afraid to give rituximab (due to expected overimmunosuppression), we prescribed the oral TPO-receptor agonist (eltrombopag). Patient responded after 17 days of therapy, to the final dose of 50 mg/d (approx. 2 mg/kg). The antiplatelet antibodies disappeared after four plasmapheresis. Overall, the therapy was continued for 7 weeks and was stopped at platelet count of 433 000/μL. Platelet count remained stable in 8-month follow-up. Combination of plasmapheresis and TPO-receptor agonist was effective in post-renal transplant acute ITP in patient with SIOD.
