Improved long-term outcome of children with congenital diarrhea followed by an intestinal rehabilitation program.

BACKGROUND: Long-term outcomes of congenital diarrheas and enteropathies (CODE) are poorly described. We evaluated the morbidity and mortality of children with CODE followed by an intestinal rehabilitation program (IRP) compared to children with short bowel syndrome (SBS). METHODS: Matched case-control study of children with intestinal failure (IF) due to CODE (diagnosed between 2006 and 2020; N = 15) and SBS (N = 42), matched 1:3, based on age at diagnosis and duration of parenteral nutrition (PN). Nutritional status, growth, and IF-related complications were compared. Survival and enteral autonomy were compared to a nonmatched SBS cohort (N = 177). RESULTS: Fifteen CODE patients (five males, median age 3.2 years) were followed for a median of 2.9 years. Eleven children were alive at the end of the follow-up, and two achieved enteral autonomy. The CODE group had higher median PN fluid and calorie requirements than their matched SBS controls at the end of the follow-up (83 vs. 45 mL/kg/day, p = 0.01; 54 vs. 30.5 kcal/kg/day, p < 0.01), but had similar rates of growth parameters, intestinal failure associated liver disease, central venous catheter complications and nephrocalcinosis. Kaplan-Meier analyses of 10-year survival and enteral autonomy were significantly lower in CODE patients compared to the nonmatched SBS population (60% vs. 89% and 30% vs. 87%, respectively; log-rank p < 0.008). CONCLUSIONS: Despite higher PN needs in CODE, rates of IF complications were similar to matched children with SBS. Enteral autonomy and survival rates were lower in CODE patients. Treatment by IRP can mitigate IF-related complications and improve CODE patient's outcome.

The Variable Response to Teduglutide in Pediatric Short Bowel Syndrome: A Single Country Real-Life Experience.

OBJECTIVES: The glucagon-like peptide-2 analog Teduglutide has been shown to enhance intestinal absorption and decrease parenteral nutrition (PN) requirements in short bowel syndrome (SBS). As data in children is limited, we evaluated nationwide real-life experience and treatment outcome in children with SBS. METHODS: Longitudinal data of children treated with Teduglutide for ≥3 months was collected. Data included demographic and medical background, anthropometrics, laboratory assessments and PN requirements. Treatment response was defined as >20% reduction in PN requirement. RESULTS: The study included 13 patients [54% males, median (interquartile range {IQR}) age of 6 (4.7-7) years]. The most common SBS etiology was necrotizing enterocolitis (38%), and median (IQR) small bowel length was 20 (15-40) cm. Teduglutide treatment ranged between 3 and 51 months [median (IQR) of 18 (12-30) months], with 10 patients (77%) treated >1 year. Response to treatment was observed in 8 patients (62%), with a mean [±standard deviation (SD)] treatment duration of 5.9 (±3.2) months. Among responders, 2 patients were weaned off PN and additional 4 decreased PN needs by >40%. There was a median (IQR) reduction in PN volume/kg of 36% (15%-55%) and in PN energy/kg of 27% (6%-58%). Response was not associated with patients' background, and no correlation was found with bowel length or PN dependency at baseline. CONCLUSIONS: Real-life response to Teduglutide is highly variable among children with SBS. While most patients did reach 20% reduction in PN, less achieved further significant reduction or enteral autonomy. No predictive factors of response to treatment were identified, and large multicenter studies are needed to elucidate predictive factors and long-term outcome.

To Be Oats or Not to Be? An Update on the Ongoing Debate on Oats for Patients With Celiac Disease.

To date, the only known effective treatment for celiac disease (CD) is a strict gluten-free diet (GFD) for life. Patients with CD often find it difficult to adhere to strict GFD. Oats, compared with wheat, barley, and rye, contain less amounts of prolamins. Inclusion of oats in a GFD might be valuable due to their nutritional and health benefits and increase of food variety. Therefore, they may potentially improve feeding diversity for these children and improve taste and satiety. We reviewed the literature to evaluate the safety of oats in CD patients. We have searched PUBMED, societal guidelines and national health authorities' recommendations. The following aspects were reviewed: gastrointestinal symptoms, malabsorption, serology including specific avenin antibodies, mucosal changes, avenin toxicity, immunogenicity of oats, and quality of life. We also referred to wheat contamination of oat products, the safe amount of oats for CD patients and the type of oats recommended. Data support that pure oats are well-tolerated by most CD patients, at moderate amounts (20-25 g/day dry rolled oats for children; 50-70 g/day for adults). Nevertheless, since the potential for sensitivity/toxicity exists, oats should be added with caution to a GFD, only after all CD symptoms including weight loss and growth disturbances have resolved, after at least 6 months of conventional GFD and probably also after normalization of serology. The need for pre exposure biopsy is unclear and should be considered on an individual basis.

Growth hormone deficiency in children with antenatal Bartter syndrome.

Background Bartter syndrome is a group of rare autosomal-recessive renal disorders characterized by hypokalemic hypochloremic metabolic alkalosis associated with severe growth failure; the exact causes for growth retardation are unclear. GH deficiency (GHD) has been reported in a few cases of Bartter syndrome. The aim of our study was to determine the prevalence of GHD in children with antenatal Bartter syndrome and to assess their response to GH therapy. Methods Ten patients aged 1.5-14.5 years and diagnosed with antenatal Bartter syndrome were enrolled. Seven children with short stature underwent GH stimulation tests. Results Common presenting symptoms were failure to thrive and polyuria. The mean patient height at study entry was -2.7 standard deviation (SD) (range 0.89 to -5.95) and mean weight (SD) was -1.7 (range 1.89 to -4.11). A decline in height and weight (SD) was observed over the years. GHD was diagnosed in four children and GH therapy was started in all of them. Two patients responded very well and gained >1 SD in height, one patient stopped therapy due to non-adherence and one had a poor response. Conclusions In addition to other important causes for poor growth in antenatal Bartter syndrome, our findings suggest that GHD should also be considered as a cause of growth retardation and therefore, clinical assessment of the GH axis is recommended. GH therapy has a role in the treatment of growth failure in some individuals with Bartter syndrome.
