Consensus for criteria of running a pediatric inflammatory bowel disease center using a modified Delphi approach.

Background: Good quality of care for inflammatory bowel disease (IBD) depends on high-standard management and facility in the IBD center. Yet, there are no clear measures or criteria for evaluating pediatric IBD (PIBD) center in China. The aim of this study was to develop a comprehensive set of quality indicators (QIs) for evaluating PIBD center in China.

Relationship between maternal-infant gut microbiota and infant food allergy.

The gut microbiota plays a crucial role in food allergies. We sought to identify characteristics of the maternal gut microbiota in the third trimester and the infant gut microbiota in early life and the association of these microbiotas with infant food allergy. A total of 68 healthy pregnant women and their full-term newborns were selected from a cohort of 202 mother-infant pairs; among them, 24 infants had been diagnosed with food allergy within 1 year of age, whereas 44 infants were healthy without allergic symptoms.

A Case Report and Literature Review of Mesalazine-Induced Kidney Injury in a Pediatric Patient With Ulcerative Colitis.

Background: Mesalazine, a preparation of 5-aminosalicylic acid, is a medication widely used in clinical practice as a first-line therapy in the treatment of mild and moderate inflammatory bowel disease. However, mesalazine has nephrotoxicity and can cause adverse events in the kidney system. While these adverse reactions are very rare, they may have serious consequences.

Metabolic Phenotype and Microbiome of Infants Fed Formula Containing Strain F-19.

Early childhood nutrition drives the development of the gut microbiota. In contrast to breastfeeding, feeding infant formula has been shown to impact both the gut microbiota and the serum metabolome toward a more unfavorable state. It is thought that probiotics may alter the gut microbiota and hence create a more favorable metabolic outcome.

Association Between Breastmilk Microbiota and Food Allergy in Infants.

Regulating the composition of human breastmilk has the potential to prevent allergic diseases early in life. The composition of breastmilk is complex, comprising varying levels of oligosaccharides, immunoactive molecules, vitamins, metabolites, and microbes. Although several studies have examined the relationship between different components of breastmilk and infant food allergies, few have investigated the relationship between microorganisms in breastmilk and infant food allergy.

A partially hydrolyzed formula with synbiotics supports adequate growth and is well tolerated in healthy, Chinese term infants: A double-blind, randomized controlled trial.

Objectives: The aim of this study was to evaluate growth and gastrointestinal tolerance in infants fed a partially hydrolyzed protein formula (pHF) with a synbiotic mixture of short-chain galacto-oligosaccharides and long-chain fructooligosaccharides (scGOS/lcFOS; 9:1) and Bifidobacterium breve M-16V (test formula) compared with an intact protein infant formula (IF) with scGOS/lcFOS (control formula).

Methods: This randomized, double-blind, controlled, multicenter trial enrolled healthy, fully formula-fed Chinese infants (≤44 d) who received either the test (n = 112) or control formula (n = 112) until 17 wk of age. Fully breastfed infants served as a reference (n = 60).

Acute peritoneal dialysis is an efficient and reliable alternative therapy in preterm neonates with acute kidney injury.

Background: This study aimed to assess the underlying causes and outcomes of acute peritoneal dialysis (APD) and the complications of PD procedure in preterm neonates with acute kidney injury (AKI).

Methods: A retrospective study of 21 preterm neonates who underwent APD in a neonatal intensive care unit (NICU) in Peking University Third Hospital between 2016 and 2019 was conducted. The demographic, clinical, biochemistry, and PD procedure--related information of the neonates was analyzed.

Serum cytokine patterns are modulated in infants fed formula with probiotics or milk fat globule membranes: A randomized controlled trial.

Background: Proteins and lipids of milk fat globule membrane (MFGM) and probiotics are immunomodulatory. We hypothesized that Lactobacillus paracasei ssp. paracasei strain F19 (F19) would augment vaccine antibody and T helper 1 type immune responses whereas MFGM would produce an immune response closer to that of breastfed (BF) infants.

Altered gut microbiota is associated with feeding intolerance in preterm infants.

Background: Feeding intolerance (FI) is a common complication that may cause great harm to preterm infants. The mechanism of FI remains unclear, but probiotics may help prevent and alleviate its symptoms. We hypothesized that the alteration in gut microbiota may be associated with the development of FI.

Milk Fat Globule Membrane as a Modulator of Infant Metabolism and Gut Microbiota: A Formula Supplement Narrowing the Metabolic Differences between Breastfed and Formula-Fed Infants.

Scope: Milk fat globule membrane (MFGM) is an important component of milk that has previously been removed in the manufacture of infant formulas, but has recently gained attention owing to its potential to improve immunological, cognitive, and metabolic health. The goal of this study is to determine whether supplementing MFGM in infant formula would drive desirable changes in metabolism and gut microbiota to elicit benefits observed in prior studies.

Methods And Results: The serum metabolome and fecal microbiota are analyzed using H NMR spectroscopy and 16S rRNA gene sequencing respectively in a cohort of Chinese infants given a standard formula or a formula supplemented with an MFGM-enriched whey protein fraction.

Comparison of Meconium Microbiome in Dizygotic and Monozygotic Twins Born by Caesarean Section (CS).

The early-life microbiota triggers life-long effects on physiological functions and health disorders. Previous studies in adult twins or animal models have revealed associations between host genetics and the harmonious microbiota. However, such associations may be obscured by the fact that each intra-pair of twins will continually encounter various environmental factors as they grow up.

Neonatal hair profiling reveals a metabolic phenotype of monochorionic twins with selective intrauterine growth restriction and abnormal umbilical artery flow.

Background: Selective intrauterine fetal growth restriction (sIUGR) in monochorionic diamniotic twins, especially types 2&3 with abnormal umbilical artery Doppler, results in increased risk of fetal/perinatal mortality and postnatal disability. We investigate whether the hair metabolome profiles of neonates were associated with the pathophysiological differences across the different clinical forms of sIUGR in twins.

Methods: Hair samples were collected at delivery from 10 pairs of type 1 sIUGR twins, 8 pairs of types 2&3 sIUGR twins, and 11 pairs of twins without sIUGR.

Feeding Infants Formula With Probiotics or Milk Fat Globule Membrane: A Double-Blind, Randomized Controlled Trial.

To evaluate effects on growth and infection rates of supplementing infant formula with the probiotic ssp. strain F19 (F19) or bovine milk fat globule membrane (MFGM). In a double-blind, randomized controlled trial, 600 infants were randomized to a formula supplemented with F19 or MFGM, or to standard formula (SF).

Effects of Conventional Milk Versus Milk Containing Only A2 β-Casein on Digestion in Chinese Children: A Randomized Study.

Objectives: In this study, we hypothesized that replacing conventional milk, which contains A1 and A2 β-casein proteins, with milk that contains only A2 β-casein in the diet of dairy or milk-intolerant preschoolers (age 5 to 6 years) would result in reduced gastrointestinal symptoms associated with milk intolerance, and that this would correspond with cognitive improvements.

Methods: This randomized, double-blind, crossover study aimed to compare the effects of 5 days' consumption of conventional milk versus milk containing only A2 β-casein on gastrointestinal symptoms, as assessed via visual analog scales, average stool frequency and consistency, and serum inflammatory and immune biomarkers in healthy preschoolers with mild-to-moderate milk intolerance. The study also aimed to compare changes in the cognitive behavior of preschoolers, based on Subtle Cognitive Impairment Test scores.

[Neonatal food allergy].

Food allergy is defined as abnormal immune response elicited by food intake, in which a variety of clinical symptoms will appear as a result of physiological dysfunction and/or tissue damage. Possible mechanisms for food allergy include gastrointestinal tract barrier damage, failure to induce oral immune tolerance, intrauterine sensitization, and allergen transmission during pregnancy and breastfeeding. Hereditary and environmental factors can also contribute to the disease.

Methods: A total of 213 children who had undergone gastroscopy due to upper gastrointestinal symptoms were enrolled and were divided into NG and non-NG groups according to endoscopic appearance. The histopathological features of gastric mucosa were evaluated using the updated Sydney System.

Altered fecal microbiota composition associated with food allergy in infants.

Increasing evidence suggests that perturbations in the intestinal microbiota composition of infants are implicated in the pathogenesis of food allergy (FA), while the actual structure and composition of the intestinal microbiota in human beings with FA remain unclear. Microbial diversity and composition were analyzed with parallel barcoded 454 pyrosequencing targeting the 16S rRNA gene hypervariable V1-V3 regions in the feces of 34 infants with FA (17 IgE mediated and 17 non-IgE mediated) and 45 healthy controls. Here, we showed that several key FA-associated bacterial phylotypes, but not the overall microbiota diversity, significantly changed in infancy fecal microbiota with FA and were associated with the development of FA.
