Impact of Global Economic Disparities on Practices and Outcomes of Chronic Peritoneal Dialysis in Children: Insights from the International Pediatric Peritoneal Dialysis Network Registry

♦ Background, Objectives, and Methods: The number of patients on chronic peritoneal dialysis (CPD) is increasing rapidly on a global scale. We analyzed the International Pediatric Peritoneal Dialysis Network (IPPN) registry, a global database active in 33 countries spanning a wide range in gross national income (GNI), to identify the impact of economic conditions on CPD practices and outcomes in children and adolescents. ♦ Results: We observed close associations of GNI with the fraction of very young patients on dialysis, the presence and number of comorbidities, the prevalence of patients with unexplained causes of end-stage kidney disease, and the rate of culture-negative peritonitis. The prevalence of automated PD increased with GNI, but was 46% even in the lowest GNI stratum. The GNI stratum also affected the use of biocompatible peritoneal dialysis fluids, enteral tube feeding, calcium-free phosphate binders, active vitamin D analogs, and erythropoiesis-stimulating agents (ESAs). Patient mortality was strongly affected by GNI (hazard ratio per $10 000: 3.3; 95$18 000) had higher serum parathyroid hormone (PTH) and lower serum calcium, and achieved lower hemoglobin concentrations. No impact of GNI was observed with regard to CPD technique survival or peritonitis incidence. ♦ Conclusions: We conclude that CPD is practiced successfully, albeit with major regional variation related to economic differences, in children around the globe. The variations encompass the acceptance of very young patients and those with associated comorbidities to chronic dialysis programs, the use of automated PD and expensive drugs, and the diagnostic management of peritonitis. These variations in practice related to economic difference do not appear to affect PD technique survival; however, economic conditions seem to affect mortality on dialysis and standardized height, a marker of global child morbidity

Growth in Very Young Children Undergoing Chronic Peritoneal Dialysis

Very young children with chronic kidney disease often have difficulty maintaining adequate nutrition, which contributes to the high prevalence of short stature in this population. Characteristics of the dialysis prescription and supplemental feeding via a nasogastric (NG) tube or gastrostomy may improve growth, but this is not well understood. Here, we analyzed data from 153 children in 18 countries who commenced chronic peritoneal dialysis at <24 months of age. From diagnosis to last observation, 57 patients were fed on demand, 54 by NG tube, and 10 by gastrostomy; 26 switched from NG to gastrostomy; and 6 returned from NG to demand feeding. North American and European centers accounted for nearly all feeding by gastrostomy. Standardized body mass index (BMI) uniformly decreased during periods of demand feeding and increased during NG and gastrostomy feeding. Changes in BMI demonstrated significant regional variation: 26% of North American children were obese and 50% of Turkish children were malnourished at last observation (P < 0.005). Body length decreased sharply during the first 6 to 12 months of life and then tended to stabilize. Time fed by gastrostomy significantly associated with higher lengths over time (P < 0.001), but adjustment for baseline length attenuated this effect. In addition, the use of biocompatible peritoneal dialysate and administration of growth hormone independently associated with improved length, even after adjusting for regional factors. In summary, growth and nutritional status vary regionally in very young children treated with chronic peritoneal dialysis. The use of gastrostomy feeding, biocompatible dialysis fluid, and growth hormone therapy associate with improved linear growth
