Abstract

Aim of the study: Neonatal enterostomy is a known risk for growth failure. We hypothesized that episodes of inflammation may drive a catabolic state, exploring this by assessing serum biochemistry alongside growth trajectory in enterostomy patients. Methods: A retrospective analysis of infants with histologically confirmed NEC from 01/2012e07/2021 in a tertiary neonatal surgical centre was performed. Change in weight-for-age Z-score (DZÞ between stoma formation and closure was calculated. Serum CRP (C-reactive protein), urea, and creatinine levels were recorded and duration of elevated levels calculated as Area Under Curve (AUC). We examined for trends of serum levels rising together using intersecting moving averages. Spearman's correlation analysis was performed, while multivariable linear regression examined factors associated with DZ. Results: 79 neonates were included. At stoma formation, median Z-score was 1.42 [range 4.73, þ1.3]. Sixty-two patients (78 %) had a fall in Z-score during their time with a stoma, 16 (20 %) had a DZ less than 2. Urea AUC was significantly univariably correlated with DZ and remained statistically significant in a multivariable model (Exp(B) x 100 ¼ 0.57[1, 0.09]; p ¼ 0.022). The number of biomarker peaks correlated significantly with DZ for urea (r ¼ 0.25; p ¼ 0.025) and CRP (r ¼ 0.35; p ¼ 0.0017) but not Creatinine (r ¼ 0.21; p ¼ 0.066). Analysing the number of peaks of any combination of variables coinciding was consistently significantly correlated negatively with DZ (r ¼ 0.29 to 0.27; p 0.016 for all). Conclusion: Our data shows that infants who were more severely affected by growth failure had more frequent and severe uremia while they had a stoma (suggesting a catabolic state). Disturbances in urea were commonly associated with CRP, suggesting that inflammation is a significant factor in growth failure in these infants. These findings promote aggressive management of sepsis in these infants, as well as suggesting an earlier closure of stoma to minimise their “at-risk”’ period.
