Efficacy of intradialytic amino acids on nutritional status in children with stage 5 chronic kidney disease.

ABSTRACT

BACKGROUND: Protein energy wasting (PEW) is a common cause of morbidity and mortality in patients with stage 5 chronic kidney disease (CKD 5). Intradialytic parenteral nutrition (IDPN) has been used as a therapy for preventing and treating PEW in children with CKD 5 when other conventional modalities fail. However, not enough data is available to define its effectiveness in treating malnutrition in children. This study aims to investigate potential benefits of IDPN in Egyptian children with CKD 5. METHODS: In this prospective, placebo-controlled, parallel-group single blinded study, we enrolled 50 CKD 5 patients; 25 patients (intervention group) received intravenous amino acids (KIDIMN), while 25 patients (control group) received normal saline as placebo, each given during regular dialysis 3 times a week for 9 months. Patients were subjected to nutritional assessment at baseline and 3-, 6-, and 9-month follow-up using height Z-score, hand grip strength (HGS) for muscle power assessment, body composition monitor (BCM) for assessing lean tissue mass (LTM) and adipose tissue mass (ATM), and biochemical measures including serum albumin, serum triglyceride, and serum cholesterol. RESULTS: When comparing baseline and 9-month follow-up values, significant improvement was recorded in height Z-score, LTM, and serum albumin in the intervention group unlike the control group where no significant changes were recorded. CONCLUSION: IDPN is proposed to be an effective method for preventing and treating malnutrition in children with CKD 5. However, further multi-centric studies with larger sample size and longer duration of follow-up are still recommended.
