RESUMO

BACKGROUND: Critically ill children have a high prevalence of malnutrition. Children with acute kidney injury experience high rates of protein debt. Previous research has indicated that protein provision is positively associated with survival. METHODS: This was a prospective observational study of all patients receiving CRRT for greater than 48 h at our tertiary care institution. Patients with inborn errors of metabolism were excluded. Data collection included energy, protein, and fluid volume intakes, anthropometrics, feeding modality, and route of nutrition intake. RESULTS: Forty-one patients 9 ± 6.8 years of age, 66% male, received CRRT over a 10-month time period. CRRT treatment was 17.3 ± 25 days. Forty-one percent were malnourished via anthropometric criteria at CRRT start. Median protein delivery was 2 g/kg/day (IQR 1.4-2.5). Fifty-one percent received a combination of parenteral nutrition (PN) and enteral/oral feedings (EN), 34% received only PN, and 12% received only EN. Percentage of time meeting protein goals by modality was 27.6%, 34.6%, and 65.3% for those patients receiving solely EN, PN, and EN + PN combination, respectively. When weaned to only EN support from combination PN + EN, the average percentage of time protein goals were met decreased to 20.5% (p < 0.01). CONCLUSIONS: Without PN, patients on enteral/oral nutrition support fail to meet appropriate protein prescription. Transition of parenteral to enteral feeds was identified as a period of nutritional risk in children receiving CRRT.

RESUMO

BACKGROUND: Management of chronic kidney disease mineral bone disorder (CKD-MBD) in pediatric patients with end-stage renal disease (ESRD) is challenging. While the use of calcimimetics is well-studied in adults on dialysis, few studies have been performed in pediatrics. Little is known about the use of cinacalcet in young children with ESRD. The aim of this study was to report the efficacy and safety of cinacalcet for treatment of secondary hyperparathyroidism in chronic dialysis patients younger than 5 years. MATERIALS AND METHODS: We included children aged < 5 years on chronic dialysis, either hemodialysis (HD) or peritoneal dialysis (PD), who were prescribed cinacalcet for more than 1 month. Retrospective chart review was performed to gather demographics, dialysis prescription, relevant mineral imbalance laboratory parameters, and medications. Data was collected for 6 consecutive months. RESULT: 18 patients (9 male), mean age at initiation of cinacalcet was 2.3 years; 13 PD and 5 HD. Average starting dose of cinacalcet: 6.2 mg daily, 0.55 mg/kg/day. Average time on dialysis was 14.4 months. Parathyroid hormone significantly decreased over the 1st month following initiation of cinacalcet from 929 (IQR 572 - 1,056) to 427 (IQR 256 - 778) pg/mL, p = 0.009. Three patients developed asymptomatic hypocalcemia (Ca < 9.4 mg/dL). Serum phosphorous decreased after initiation, and this was persistent at 6 months. Significant improvement in linear growth was observed while on cinacalcet and growth hormone (GH). CONCLUSION: Cinacalcet can be effectively used in young children on dialysis with minimal side effects. Good linear growth was seen in patients on cinacalcet and GH therapy. Long-term large scale data is necessary to confirm. Institution-based management algorithm incorporating cinacalcet would be helpful to maintain uniformity in role of cinacalcet for management of CKD-MBD.
