Nutritional management and outcomes of malnourished children under 2 years with intestinal failure

This study aimed to assess the evolution of nutritional status, parenteral nutrition (PN) composition, and PN dependence index (PNDI) in children under 2 years old with intestinal failure (IF) and malnutrition.

This retrospective cohort included patients admitted between November 1, 2016, and August 31, 2021, with IF, age ≤24 months, and weight-for-age (Wt/A) <-2 standard deviation with a follow-up of 12 months. Data collected included demographic, anthropometric, biochemical, and nutritional information. The PNDI was compared between enteral autonomy (EA) and nonenteral autonomy (non-EA) groups.

Thirty patients (16 males, 53.33%) were included, and short bowel syndrome (SBS) was the leading cause of IF (n = 27, 90%). The mean age at admission was 7.23 ± 3.90 months, and 36.66% of the patients had a conjugated bilirubin (CB) level >2 mg/dL; 87% had a Wt/A z-score <-3 and 90% had a height-for-age (Ht/A) z-score <-3. At 5 months, the mean Wt/A z-score improved to -1.82. At admission, median protein, lipid, and glucose intake on PN were 3, 1.6, and 17.27 g/kg/day, respectively. In the PNDI analysis, the EA group had a mean index of 141% versus 158% for the non-EA group at admission, with no statistical differences. From the sixth month onward, the EA group showed a significantly lower PNDI (50% vs. 108% for non-EA patients; p = 0.032). Both groups demonstrated adequate nutritional recovery.

Adequate multidisciplinary care can reverse severe malnutrition, and the PNDI may be a predictor of EA.
