Variability in Swallowed Topical Corticosteroid Practice Patterns for Treatment of Pediatric Eosinophilic Esophagitis.

Given the variety of preparations and lack of standardization of swallowed topical corticosteroids (STC) for treatment of eosinophilic esophagitis (EoE), we sought to better understand STC prescribing practices of pediatric gastroenterologists. A 12-question survey was distributed to members of North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Eosinophilic Gastrointestinal Disease Special Interest Group and responses were analyzed. Forty-two of 68 physicians responded. Oral viscous budesonide (OVB) was overall first choice STC in 31 (74%) survey respondents, with OVB most frequently utilized in patients under 5 years old and fluticasone propionate in patients 13-18 years old. Nineteen types of mixing vehicles were used for OVB preparation, the 3 most frequent being sucralose, honey, and artificial maple syrup. Insurance coverage, cost, and patient compliance were most frequently cited barriers to STC use. Highly variable STC prescribing practices reported by this group highlights the need for standardization of STC treatment in EoE.

Factors Affecting Selenium Status in Infants on Parenteral Nutrition Therapy.

INTRODUCTION: Selenium is an essential micronutrient that must be supplemented in infants and young children on exclusive parenteral nutrition (PN). We examined selenium status and clinical factors associated with a deficiency in infants on PN. METHODS: This was a retrospective cohort study of pediatric patients receiving PN with routine monitoring of selenium status. Deficiency was diagnosed using age-based norms of plasma selenium status. Associations between selenium deficiency and the following clinical factors were examined: birthweight status: extremely low birthweight (ELBW) versus very low birthweight (VLBW) versus low birthweight (LBW) versus normal birthweight (NBW), serum albumin status, presence of cholestasis, and co-administration of enteral feeds. RESULTS: A total of 42 infants were included with gestational age [median (interquartile range)] 28 weeks (25,34). The prevalence of selenium deficiency was 80% and the prevalence of albumin deficiency was 87.5%. The odds of selenium deficiency were higher in ELBW infants (odds ratio = 17.84, 95% confidence interval [4.04-78.72], P < 0.001) and VLBW infants (odds ratio = 16.26, 95% confidence interval [1.96-135.04], P < 0.001) compared to NBW infants. The odds of selenium deficiency were 5-fold higher in patients with low serum albumin (odds ratio = 5.33, 95% confidence interval [1.39-20.42], P = 0.015). There were no associations seen between selenium status and presence of cholestasis or co-administration of enteral feeds. CONCLUSION: In this cohort of infants on PN therapy, the main clinical factors associated with selenium deficiency were presence of hypoalbuminemia and history of ELBW or VLBW. These findings support dual measurement of serum albumin and serum selenium to improve interpretation of selenium status.

Efficacy of Fecal Microbiota Transplantation for Clostridium difficile Infection in Children.

BACKGROUND & AIMS: Fecal microbiota transplantation (FMT) is commonly used to treat Clostridium difficile infection (CDI). CDI is an increasing cause of diarrheal illness in pediatric patients, but the effects of FMT have not been well studied in children. We performed a multi-center retrospective cohort study of pediatric and young adult patients to evaluate the efficacy, safety, and factors associated with a successful FMT for the treatment of CDI. METHODS: We performed a retrospective study of 372 patients, 11 months to 23 years old, who underwent FMT at 18 pediatric centers, from February 1, 2004, to February 28, 2017; 2-month outcome data were available from 335 patients. Successful FMT was defined as no recurrence of CDI in the 2 months following FMT. We performed stepwise logistic regression to identify factors associated with successful FMT. RESULTS: Of 335 patients who underwent FMT and were followed for 2 months or more, 271 (81%) had a successful outcome following a single FMT and 86.6% had a successful outcome following a first or repeated FMT. Patients who received FMT with fresh donor stool (odds ratio [OR], 2.66; 95% CI, 1.39-5.08), underwent FMT via colonoscopy (OR, 2.41; 95% CI, 1.26-4.61), did not have a feeding tube (OR, 2.08; 95% CI, 1.05-4.11), or had 1 less episode of CDI before FMT (OR, 1.20; 95% CI, 1.04-1.39) had increased odds for successful FMT. Seventeen patients (4.7%) had a severe adverse event during the 3-month follow-up period, including 10 hospitalizations. CONCLUSIONS: Based on the findings from a large multi-center retrospective cohort, FMT is effective and safe for the treatment of CDI in children and young adults. Further studies are required to optimize the timing and method of FMT for pediatric patients-factors associated with success differ from those of adult patients.

Pediatric Celiac Disease and Eosinophilic Esophagitis: Outcome of Dietary Therapy.

OBJECTIVE: The coexistence of celiac disease (CeD) and eosinophilic esophagitis (EoE) in pediatric patients has been increasingly recognized. In the current study, we have aimed to assess the outcomes of therapeutic dietary interventions in a cohort of pediatric patients with CeD and EoE. METHODS: Pediatric patient records obtained from the University of Chicago Celiac Center Database from August 2008 to July 2013 were reviewed. Information was collected on patients with concomitant CeD and EoE regarding age, sex, dates of diagnoses, presenting symptoms, length of symptoms before diagnosis, familial and personal atopic history, dietary therapy, and esophageal histologic response to dietary therapy. RESULTS: A total of 350 records of patients with CeD were reviewed. Twenty-two (6.3%) had a confirmed diagnosis of CeD and EoE, 17 had repeat biopsies. Four of 17 (23.5%) had resolution of esophageal eosinophilia on an exclusive gluten-free diet, 10 of 17 (59%) required additional eliminations to show histologic resolution, 1 of 17 (6%) had not reached histological remission, and 2 of 17 (12%) were lost to follow-up. Success rates of single food reintroductions were: soy 5 of 5 (100%), eggs 3 of 5 (60%), dairy 3 of 7 (43%), nuts 2 of 4 (50%), and fish 2 of 4 (50%). CONCLUSIONS: To our knowledge, this is the largest pediatric study to assess the histologic outcome of EoE-associated esophageal eosinophilia in response to dietary management of pediatric patients with concomitant CeD and EoE. We demonstrate that soy is well tolerated in this cohort, and suggest that reintroducing this food first, or trialing a soy-inclusive elimination diet is a viable strategy.

Manifestations of Cow's-Milk Protein Intolerance in Preterm Infants.

OBJECTIVES: Cow's-milk protein intolerance (CMPI) is poorly recognized in preterm infants. This study examined the clinical events that preceded the diagnosis of CMPI in preterm infants. METHODS: This was a retrospective study of infants in a level-III neonatal intensive care unit of those who received parenteral nutrition (PN) support during a 12-month period. Parameters assessed included birth weight (g), diagnosis, duration and frequency on PN, type of enteral feeds at initiation, and achievement of enteral autonomy. CMPI was diagnosed based on persistent feeding intolerance that resolved after change of feeds from intact protein to a protein hydrolysate or crystalline amino acid formula. RESULTS: Three hundred forty-eight infants with birth weight (median/range) 1618 g (425-5110) received PN. Fifty-one (14%) infants required multiple courses of PN, and 19 of 348 (5%) were diagnosed with CMPI. The requirement for multiple courses on PN versus single course was associated with a high likelihood of CMPI: 14 of 51 versus 5 of 297, P < 0.001. Nine of the 14 infants identified with CMPI were initially diagnosed with necrotizing enterocolitis (NEC) after a median duration of 22 days (19-57) on intact protein feeds. After recovery from NEC, they had persistent feeding intolerance including recurrence of "NEC-like illness" (N = 3) that resolved after change of feeds to a protein hydrolysate or crystalline amino acid formula. CONCLUSIONS: The requirement for multiple courses of PN because of persistent feeding intolerance after recovery from NEC and recurrence of "NEC-like illness" may be a manifestation of CMPI in preterm infants.

Efficacy and Outcomes of Faecal Microbiota Transplantation for Recurrent Clostridioides difficile Infection in Children with Inflammatory Bowel Disease.

BACKGROUND: Children with inflammatory bowel disease [IBD] are disproportionally affected by recurrent Clostridioides difficile infection [rCDI]. Although faecal microbiota transplantation [FMT] has been used with good efficacy in adults with IBD, little is known about outcomes associated with FMT in paediatric IBD. METHODS: We performed a retrospective review of FMT at 20 paediatric centres in the USA from March 2012 to March 2020. Children with and without IBD were compared with determined differences in the efficacy of FMT for rCDI. In addition, children with IBD with and without a successful outcome were compared with determined predictors of success. Safety data and IBD-specific outcomes were obtained. RESULTS: A total of 396 paediatric patients, including 148 with IBD, were included. Children with IBD were no less likely to have a successful first FMT then the non-IBD affected cohort [76% vs 81%, p = 0.17]. Among children with IBD, patients were more likely to have a successful FMT if they received FMT with fresh stool [p = 0.03], were without diarrhoea prior to FMT [p = 0.03], or had a shorter time from rCDI diagnosis until FMT [p = 0.04]. Children with a failed FMT were more likely to have clinically active IBD post-FMT [p = 0.002] and 19 [13%] patients had an IBD-related hospitalisation in the 3-month follow-up. CONCLUSIONS: Based on the findings from this large US multicentre cohort, the efficacy of FMT for the treatment of rCDI did not differ in children with IBD. Failed FMT among children with IBD was possibly related to the presence of clinically active IBD.

Devastating Postpartum Complications in an Adolescent Linked to New-Onset Inflammatory Bowel Disease and Antiphospholipid Antibody Syndrome.

Pregnancy can affect the severity of inflammatory bowel disease (IBD), and pregnant women with IBD are at a higher risk for venous thromboembolism compared with the general population. We report a previously healthy 16-year-old female who developed bloody diarrhea and venous thromboembolism following childbirth, with further evaluation revealing IBD and antiphospholipid antibody syndrome. This case highlights the impact pregnancy can have on IBD and other immunological disorders, and the potentially life-threatening risk of thrombosis in pregnant women with IBD.

Effects of Chromium on Glucose Tolerance in Infants Receiving Parenteral Nutrition Therapy.

OBJECTIVES: Early hyperglycemia is prevalent in preterm infants receiving parenteral nutrition (PN) therapy. Chromium improves glucose tolerance by potentiating the action of insulin. Therefore, we hypothesized that supplementing PN with chromium would improve glucose tolerance and PN calorie delivery in infants during the first week of life. METHODS: We collected data on neonates receiving PN initiated at birth with chromium (0.2 mcg/kg/d) started either on days 5-7 (group A) vs day 1 (group B) on PN and compared glucose tolerance and PN calorie administration over the first week of life. RESULTS: For similar mean serum glucose concentrations between group A (n = 348) and B (n = 358) (107 ± 48 vs 111 ± 52 mg/dL, P = .3), infants in group B tolerated higher glucose infusion rates and received more PN calories during the first week of life: 8.4 ± 2 vs 8 ± 2 mg/kg/min (P < .001) and 74.8 ± 23 vs 71.5 ± 12 kcal/kg/d (P = .017), respectively. The difference in calories delivered was more pronounced among very low birth weight (VLBW) infants compared with infants >1500 g: 76.5 ± 14 vs 72.4 ± 11 kcal/kg/d (P = .009) and 73.8 ± 27 vs 70.3 ± 12 kcal/kg/d (P = .079), respectively. CONCLUSIONS: PN chromium supplementation resulted in better glucose tolerance and calorie delivery during the first week of life, especially in VLBW infants. This supports chromium's essential role in enhancing glucose tolerance during PN therapy in VLBW infants at risk for early hyperglycemia.

Colonic Necrosis in a 4-Year-Old with Hyperlipidemic Acute Pancreatitis.

Here we report the case of a 4-year-old male with severe acute pancreatitis due to hyperlipidemia, who presented with abdominal pain, metabolic abnormalities, and colonic necrosis. This colonic complication was secondary to the extension of a large peripancreatic fluid collection causing direct serosal autodigestion by pancreatic enzymes. Two weeks following the initial presentation, the peripancreatic fluid collection developed into a mature pancreatic pseudocyst, which was percutaneously drained. To our knowledge, this is the youngest documented pediatric case of colonic necrosis due to severe pancreatitis and the first descriptive pediatric case of a colonic complication due to hyperlipidemia-induced acute pancreatitis.
