In children, CMV-associated protein-losing enteropathy (PLE) is characterised by a benign course and spontaneous healing but can lead to generalised oedema. Poorly defined, it is diagnosed after unnecessary invasive tests. Children with CMV-associated PLE between 2009 and 2019 in two French hospitals are retrospectively described. Clinical and biological signs, CMV identification, endoscopy and histological findings, disease management and course are analysed. CMV-associated PLE is proven in 21 immunocompetent and 22 immunosuppressed patients, with ages consistent with primo-infection and reactivation, respectively. The digestive symptoms prevail in immunocompetent children, mainly with vomiting (85.7% versus 50%, CI [1.2; 39.2], p = 0.02). Immunocompetent patients show more oedema (61.9% versus 4.5%, CI [3.6; 1502.4], p < 0.001), linked to more severe hypoalbuminemia (21.2 g/L [17.6–25.7] versus 29.6 g/L [24.9–33.9], p = 0.01). A severe course is observed in 23.8% of the immunocompetent patients and 54.5% of the immunosuppressed ones (p = 0.06). Evidence of CMV infection based on non-invasive methods is found on 88.9% of immunocompetent and 95.5% of immunosuppressed patients (p = 0.58), while endoscopy was performed on 95.2% and 100% of them, respectively (p = 0.48), without any therapeutic change. Thus, CMV-associated PLE should be suspected in children with generalised oedema. Not as benign as previously described, it can be confirmed using non-invasive tests. [ABSTRACT FROM AUTHOR]

Before reaching its adult-type composition around the age of 3 to 5 years, the infant's intestinal microbiota gradually establishes since birth according to a trajectory influenced by ecological and environmental factors. However, the most important thing is that this trajectory probably has an influence on the future health of the child. Even if, to date, data issued from research do not allow us to give practical management advice, it is very likely that in the years to come we will be able to optimize the trajectory of implantation of the intestinal microbiota of our patients, to guarantee them the best chance of remaining healthy throughout their whole lives.

Background: Laparoscopic Nissen fundoplication (LNF) and gastrostomy tube (GT) placement may be performed concomitantly in children with gastro-esophageal reflux disease (GERD) and failure to thrive. We aimed to evaluate the rate and risk factors for LNF failure in children undergoing concomitant LNF/GT.Methods: A retrospective multi-institutional cohort study was conducted, reviewing patients that underwent LNF (2005-2014). Data collected included patient demographics, comorbidities, and type of GT (laparoscopy- or endoscopy-assisted). The primary outcome measure was LNF failure. Data was compared using contingency tables or Mann-Whitney tests, when appropriate. An exploratory analysis by Kaplan-Meier survival and Cox proportional hazards analysis was performed to determine predictors of time to LNF failure after LNF/GT.Results: Of 189 children that underwent LNF, 99 (52%) had a concomitant GT (55% laparoscopy-, 45% endoscopy-assisted). LNF failed in 15% after LNF/GT and in 17% after LNF alone (p = 0.84), at a median age of 23 months (IQR 8-41). Using univariate analysis, we found that a younger age at the time of surgery (p = 0.05), prematurity (p = 0.0018), esophageal atresia (p = 0.01), and endoscopy-assisted GT (p = 0.02) were potential predictors of LNF failure after LNF/GT. After multivariate regression analysis, prematurity (p = 0.007) remained significantly associated with LNF failure after LNF/GT. No predictive factors for LNF failure after LNF alone were identified.Conclusions: Concomitant GT insertion and LNF is a common practice, as half of the children that undergo LNF also received GT insertion. Children born preterm or with esophageal atresia comprise a fragile population at high-risk of LNF failure after LNF/GT. Prospective, multicentric studies are needed to evaluate the best GT technique to use in children undergoing LNF. [ABSTRACT FROM AUTHOR]

Lactoferrin is one of the most represented and important bioactive proteins in human and mammal milk. In humans, lactoferrin is responsible for several actions targeting anti-infective, immunological, and gastrointestinal domains in neonates, infants, and young children. Evidence-based data vouch for the ability of supplemented lactoferrin to prevent sepsis and necrotizing enterocolitis in preterm infants and to reduce the burden of morbidity related to gastrointestinal and respiratory pathogens in young children. However, several issues remain pending regarding answers and clarification related to quality control, correct intakes, optimal schedules and schemes of supplementations, interactions with probiotics, and different types of milk and formulas. This review summarizes the current evidence regarding lactoferrin and discusses the areas in need of further guidance prior to the adoption of strategies that include a routine use of lactoferrin in neonates and young children.

To date, fecal microbiota transplantation (FMT) is the only way to restore a healthy and diverse microbiota in case of an imbalance called dysbiosis. Its effectiveness in case of relapsing Clostridium difficile infection is well established. On the other hand, in other conditions such as inflammatory bowel diseases or metabolic diseases where a correction of dysbiosis must be constantly renewed, FMT is not yet a well-established treatment. Studies on practical problems (fresh/frozen stools, donor choice...) still need to be carried out before a consensual and definitive answer can be given to these questions. [ABSTRACT FROM AUTHOR]

Background: The aim of our study was to report our experience in extended Hirschsprung's disease (HD) in children operated on by laparoscopy.Patients and Methods: Retrospective data collection from a single center from 1991 to 2013 concerned extended forms of HD operated on by laparoscopic Duhamel procedure and included extension of aganglionosis, comorbidities, short and late postoperative outcome, and results of endoscopy when performed.Results: Thirty patients presented an extended form of aganglionosis: 5 involving the transverse colon, 10 the right colon, and 15 the ileum (median length = 15 cm, range 1-60). Short-term outcome showed 13% postoperative complications requiring redo-surgery: occlusion (n = 2), wall abscess (n = 1), and anastomotic leak (n = 1). Median follow-up was of 5 years (range: 1-19 years). Satisfying bowel control was reached in 53%, and 46% had a weight-for-age reference curve up to -1 SD. They had four stools per day on average, 13% of soiling, 6% of constipation, and 26% of recurrent abdominal distention. Late enterocolitis occurred in 22% (n = 7): 6 with ileum involvement and 1 extended to the transverse colon. Endoscopy showed Crohn-like ulcerations in 100% of these cases.Conclusion: Laparoscopic Duhamel procedure is a safe and effective surgical technique in the management of extended forms of HD, with a low postoperative morbidity, but the frequent occurrence of late enterocolitis associated with Crohn-like ulcerations impairs the late outcome. Link between HD and Crohn disease still requires to be investigated. [ABSTRACT FROM AUTHOR]

Most of the Human diseases affecting westernized countries are associated with dysbiosis and loss of microbial diversity in the gut microbiota. The Western way of life, with a wide use of antibiotics and other environmental triggers, may reduce the number of bacterial predators leading to a decrease in microbial diversity of the Human gut. We argue that this phenomenon is similar to the process of ecosystem impoverishment in macro ecology where human activity decreases ecological niches, the size of predator populations, and finally the biodiversity. Such pauperization is fundamental since it reverses the evolution processes, drives life backward into diminished complexity, stability, and adaptability. A simple therapeutic approach could thus be to reintroduce bacterial predators and restore a bacterial diversity of the host microbiota. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Aims Methods Results Conclusions Detailed comparative assessment of procedure‐related factors associated with faecal microbiota transplantation (FMT) efficacy in Clostridioides difficile infection (CDI) is limited.We took advantage of the differences in procedures at the various French FMT centres to determine clinical and procedure‐related factors associated with FMT success in CDI.We performed a nationwide retrospective multicentre cohort study. All FMTs performed within The French Faecal Transplant Group for CDI from 2018 to 2022 were included. Clinical data were collected retrospectively from recipient medical files, characteristics of stool transplant preparations were prospectively collected by each Pharmacy involved. Univariate and multivariate analyses were performed using Fisher's test and multiple logistic regression.Six hundred fifty‐eight FMTs were performed for 617 patients in 17 centres. The overall efficacy of FMT was 84.3% (520/617), with 0.5% of severe adverse events possibly related to FMT (3/658). Forty‐seven patients were treated at the first recurrence of CDI with a similar success rate (85.1%). Severe chronic kidney disease (CKD; OR: 2.18, 95%CI [1.20–3.88]), non‐severe refractory CDI (OR: 15.35, [1.94–318.2]), the use of ≥ 80% glycerol (OR: 2.52, [1.11–5.67]), insufficient bowel cleansing (OR: 5.47, [1.57–20.03]) and partial FMT retention (OR: 9.97, [2.62–48.49]) were associated with CDI recurrence within 8 weeks.Conditions of transplant manufacturing, bowel cleansing, and a route of delivery tailored to the patient's characteristics are key factors in optimising FMT efficacy. FMT at first recurrence showed high success in real‐life practice, whereas it had lower efficacy in severe CDI and non‐severe refractory CDI. [ABSTRACT FROM AUTHOR]
