Treatment of pediatric heterozygous familial hypercholesterolemia 7 years after the EAS recommendations: Real-world results from a large French cohort.

BACKGROUND: Heterozygous familial hypercholesterolemia (HeFH) predisposes to premature cardiovascular diseases. Since 2015, the European Atherosclerosis Society has advocated initiation of statins at 8-10 years of age and a low-density lipoprotein cholesterol (LDL-C) target of <135 mg/dL. Longitudinal data from large databases on pharmacological management of pediatric HeFH are lacking. OBJECTIVE: Here, we describe treatment patterns and LDL-C goal attainment in pediatric HeFH using longitudinal real-world data. METHODS: This was a retrospective and prospective multicenter cohort study (2015-2021) of children with HeFH, diagnosed genetically or clinically, aged <18 years, and followed up in the National French Registry of FH (REFERCHOL). Data on the study population as well as treatment patterns and outcomes are summarized as mean±SD. RESULTS: We analyzed the data of 674 HeFH children (age at last visit: 13.1 ± 3.6 years; 82.0 % ≥10 years; 52.5 % females) who were followed up for a mean of 2.8 ± 3.5 years. Initiation of lipid-lowering therapy was on average at 11.8 ± 3.0 years of age for a duration of 2.5 ± 2.8 years. At the last visit, among patients eligible for treatment (573), 36 % were not treated, 57.1 % received statins alone, 6.4 % statins with ezetimibe, and 0.2 % ezetimibe alone. LDL-C was 266±51 mg/dL before treatment and 147±54 mg/dL at the last visit (-44.7 %) in treated patients. Regarding statins, 3.3 %, 65.1 %, and 31.6 % of patients received high-, moderate-, and low-intensity statins, respectively. Overall, 59 % of children on statin therapy alone and 35.1 % on bitherapy did not achieve the LDL-C goal; fewer patients in the older age group did not reach the treatment goal. CONCLUSION: Pediatric patients with FH followed up in specialist lipid clinics in France receive late treatment, undertreatment, or suboptimal treatment and half of them do not reach the therapeutic LDL-C goal. Finding a more efficient framework for linking scientific evidence to clinical practice is needed.

Perinatal foodborne titanium dioxide exposure-mediated dysbiosis predisposes mice to develop colitis through life.

BACKGROUND: Perinatal exposure to titanium dioxide (TiO2), as a foodborne particle, may influence the intestinal barrier function and the susceptibility to develop inflammatory bowel disease (IBD) later in life. Here, we investigate the impact of perinatal foodborne TiO2 exposure on the intestinal mucosal function and the susceptibility to develop IBD-associated colitis. Pregnant and lactating mother mice were exposed to TiO2 until pups weaning and the gut microbiota and intestinal barrier function of their offspring was assessed at day 30 post-birth (weaning) and at adult age (50 days). Epigenetic marks was studied by DNA methylation profile measuring the level of 5-methyl-2'-deoxycytosine (5-Me-dC) in DNA from colic epithelial cells. The susceptibility to develop IBD has been monitored using dextran-sulfate sodium (DSS)-induced colitis model. Germ-free mice were used to define whether microbial transfer influence the mucosal homeostasis and subsequent exacerbation of DSS-induced colitis. RESULTS: In pregnant and lactating mice, foodborne TiO2 was able to translocate across the host barriers including gut, placenta and mammary gland to reach embryos and pups, respectively. This passage modified the chemical element composition of foetus, and spleen and liver of mothers and their offspring. We showed that perinatal exposure to TiO2 early in life alters the gut microbiota composition, increases the intestinal epithelial permeability and enhances the colonic cytokines and myosin light chain kinase expression. Moreover, perinatal exposure to TiO2 also modifies the abilities of intestinal stem cells to survive, grow and generate a functional epithelium. Maternal TiO2 exposure increases the susceptibility of offspring mice to develop severe DSS-induced colitis later in life. Finally, transfer of TiO2-induced microbiota dysbiosis to pregnant germ-free mice affects the homeostasis of the intestinal mucosal barrier early in life and confers an increased susceptibility to develop colitis in adult offspring. CONCLUSIONS: Our findings indicate that foodborne TiO2 consumption during the perinatal period has negative long-lasting consequences on the development of the intestinal mucosal barrier toward higher colitis susceptibility. This demonstrates to which extent environmental factors influence the microbial-host interplay and impact the long-term mucosal homeostasis.

Accuracy of Serological Screening for the Diagnosis of Celiac Disease in Type 1 Diabetes Children.

Background and Objectives: Patients with type 1 diabetes (T1D) are considered at high-risk for developing celiac disease (CD). The purpose of our study was to determine the prevalence of CD among children who were followed in our unit for T1D using the latest ESPGHAN guidelines, and avoiding intestinal biopsies in some of the children. Materials and Methods: We performed a prospective monocentric study, which included 663 T1D children between June 2014 and June 2016. We considered CD according to serological (tissue transglutaminase (TGAs) and endomysium antibodies) results. Children were included either at the time of T1D diagnosis or during their follow up. We looked for clinical and biochemical signs of CD, and for T1D characteristics. Results: The children's ages ranged from 11 months to 18 years. CD was confirmed in 32 out of 663 patients with T1D, with a prevalence of 4.8%. CD was excluded in 619 children and remained uncertain for 12 children, who had positive TGAs without the required criteria. We found that 95% of T1D children express HLA-DQ2 and/or -DQ8, which was 2.4 times higher than in the general population. Conclusions: An intestinal biopsy could be avoided to confirm CD in the majority of T1D children. Silent forms of CD are frequent and screening is recommended for all patients. Importantly, repeated TGA assessment is required in HLA genetically predisposed T1D patients, while it is unnecessary in the 5% who are HLA-DQ2 and -DQ8 negative.

Drugs in Focus: Domperidone.

Domperidone is a peripheral dopamine-2 receptor antagonist with prokinetic and antiemetic properties. Its prokinetic effects are mainly manifest in the upper gastrointestinal (GI) tract. Currently its use is restricted to relief of nausea and vomiting in children older than 12 years for a short period of time. However, among (pediatric) gastroenterologists, domperidone is also used outside its authorized indication ("off label") for treatment of symptoms associated with gastro-esophageal reflux disease, dyspepsia, and gastroparesis. Little is known about its efficacy in the treatment of GI motility disorders in children and controversial data have emerged in the pediatric literature. As its use is off label, appropriate knowledge of its efficacy is helpful to support an "off label/on evidence" prescription. Based on this, the purpose of this review is to summarize all evidence on the efficacy of domperidone for the treatment of GI disorders in infants and children and to report an overview of its pharmacological properties and safety profile.

Intestinal involvement in lupus: From pathophysiology to therapeutic perspectives.

Lupus erythematosus is a complex autoimmune disease characterized by skin and/or systemic involvement. Among systemic disorders, half of the patients will experience non-specific digestive symptoms, usually due to drug medication or transitory infections. In rare cases, lupus enteritis can be observed, and its diagnosis may precede the disease and/or be associated with an inflammatory bowel disease (IBD). Among the underlying mechanisms explaining the digestive damages observed in systemic lupus erythematosus (SLE) and the intestinal barrier function (IBF), increased intestinal permeability, microbiota dysbiosis, and intestinal immune system dysregulations are described in numerous murine and human studies. New therapeutic approaches in addition to conventional treatments are evoked in order to better control the IBF disruption and maybe prevent the onset or worsening of the disease. Thus, the aims of this review are to present the alterations of the digestive tract in SLE patients and the link between SLE and IBD as well as how the different elements of the IBF could participate in SLE pathogenesis.

Pediatric Magnet Ingestion, Diagnosis, Management, and Prevention: A European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) Position Paper.

Magnet ingestion is a special category of foreign body ingestion associated with high levels of morbidity and mortality worldwide, particularly if it is associated with staggered ingestion of multiple magnets or with simultaneous ingestion of other metallic foreign bodies, especially button batteries. A special category of magnet ingestion is the ingestion of earth magnets, which have higher levels of magnetism and therefore, potentially, carries a worse outcome. Legislative bodies, scientific Societies and community-led initiatives have been implemented worldwide with the aim of mitigating the effects of this growing, yet avoidable potential medical emergency. A scoping literature review summarized epidemiology, diagnosis, management, and prevention, including an algorithm for the diagnosis and management of magnet ingestion is presented and compared to previously published reviews and position papers (North American Society of Pediatric Gastroenterology, Hepatology and Nutrition, National Poison Center, Royal College of Emergency Medicine). The main emphasis of the algorithm is on identification of staggered/multiple magnet ingestion, and early joint gastroenterology and surgical consultation and management.

Impact of the HAS 2019 French guidelines on the frequency of hospital undernutrition in children.

In 2019, the French National Authority for Health (Haute Autorité de Santé, HAS) published guidelines on the diagnosis of undernutrition. The present article focuses on the impact of switching from the 2012 guidelines of the Nutrition Committee of the French Paediatric Society (CNSFP) to the HAS guidelines on the frequency of hospital undernutrition in children. We selected for the period 2010-2019 from the ePINUT database: (1) all children aged more than 2 years with (2) clinically confirmed nutritional status in (3) French sites. The frequency of undernutrition was 15.4% vs. 28.8% using the CNSFP and HAS criteria, respectively (p < 0.01; n = 6304). When compared to non-malnourished children regardless of the criteria used, malnourished children: (1) stayed longer in hospital (CNSFP: 9.0 ±â€¯11.8 vs. 6.5 ±â€¯8.7 days, p < 0.01; HAS: 7.8 ±â€¯10.1 vs. 6.4 ±â€¯8.4 days, p < 0.01), (2) gained more weight during hospitalization (% of weight at admission) (CNSFP: +1.4 ±â€¯4.1 vs. -0.3 ±â€¯3.5%, p < 0.01; HAS: +2.3 ±â€¯4.7 vs. -0.1 ±â€¯3.4%, p < 0.01), and (3) received nutritional support more frequently during hospitalization (CNSFP: 20% vs. 5%, p < 0.01; HAS: 13% vs. 4%, p < 0.01). Switching to the HAS guidelines resulted in an almost twofold higher frequency of undernutrition in hospitalized children. Initiation of nutritional care remained low considering the nutritional status. The present study warrants interventional studies to determine which children may benefit more from nutritional therapy to improve their outcome.

Hypnotherapy in Pediatric Gastroenterology.

In several countries, gut-directed hypnotherapy is becoming an established and evidence-based treatment in pediatric gastroenterology. This article describes what hypnotherapy is, offers an overview of its effect in gut-brain disorders and explains its potential mode of action. Moreover, the use of hypnotherapy in other areas of pediatric gastroenterology, as a supportive tool to reduce pain, stress, depression, and anxiety and improve quality of life, will be also discussed. Guidance toward implementing hypnotherapy in clinical practice is provided, including examples of how you can explain hypnosis to patients with gastroenterological symptoms.

Factors Predicting Statin Initiation During Childhood in Familial Hypercholesterolemia: Importance of Genetic Diagnosis.

OBJECTIVE: To identify childhood and parental factors associated with initiation of statin therapy in children with heterozygous familial hypercholesterolemia (HeFH), including underlying genetic diagnosis or parental premature atherosclerotic cardiovascular disease (ASCVD). STUDY DESIGN: This multicenter cohort study included 245 HeFH child-parent pairs from the REFERCHOL national register (2014-2020). Demographic and clinical characteristics at the last visit were collected. Vascular disease in parents was defined as a history of ASCVD, and/or a coronary artery calcium score >100, and/or stenosis of >50% in at least carotid artery. Statistical analyses included descriptive analysis, logistic regression for univariate and multivariate effects of statins, and a sensitivity analysis combining the characteristics of children and parents. RESULTS: Among the 245 children in the study cohort, 135 (58%), with a mean age of 14 ± 3 years, were treated with a statin. In multivariable analysis, the predictive childhood factors associated with statin treatment were genetic diagnosis (OR, 2.5; 95% CI, 1.3 to 4.9; P = .01), older age (OR, 4.4; 95% CI, 1.8-10.6; P = .01), more than 2 visits (OR, 2.36; 95% CI, 1.18-4.73; P = .015), and longer duration of follow-up (OR, 1.3; 95% CI, 1.1-1.6; P < .001). The predictive parental factor associated with childhood treatment was the presence of vascular disease (OR, 2.4; 95% CI, 1.0-5.7; P = .04). CONCLUSIONS: HeFH confirmed by DNA testing during childhood and a history of vascular disease in parents were independently associated with statin treatment in children with HeFH. Genetic diagnosis may be useful for cardiovascular prevention in children.

[Infant gastroesophageal reflux disease: physiological or pathological ?] / Reflux gastrooesophagien du nourrisson : physiologique ou pathologique ?

INFANT GASTRO-ESOPHAGEAL REFLUX DISEASE: PHYSIOLOGICAL OR PATHOLOGICAL ? Gastroesophageal reflux (GER) is defined by the rise of gastric contents into the esophagus, with or without externalization. GER is very common in young infants, with a peak around 4 months, and most often physiological due to high milk intakes and inappropriate relaxation of the lower esophageal sphincter. Evoking a GER disease (GERD) is not always obvious due to signs of poor specificity (crying, irritability, regurgitation). On the other hand, one should not miss warning signs evocative of GERD complicated by esophagitis or of recurrent upper respiratory or ENT infections, or even differential diagnoses (cow milk protein allergy, eosinophilic esophagitis, congenital malformations or brain tumours, etc.). The diagnosis of GERD is clinical but investigations can sometimes be discussed like esophagogastroduodenal endoscopy, 24- hour pH-metry, esophagogastroduodenal follow through. The mechanisms of GERD should be clearly explained to parents and physiological GER should be treated with non-drug measures (adaptation of milk intakes/volumes, thickeners). In the absence of improvement, avoidance of cow's milk proteins for 2 to 4 weeks can be proposed, or even treatment with proton pump inhibitors.

REFLUX GASTRO-OESOPHAGIEN DU NOURRISSON: PHYSIOLOGIQUE OU PATHOLOGIQUE ? Le reflux gastro-oesophagien (RGO) est défini par la remontée du contenu gastrique dans l'oesophage, avec ou sans extériorisation. Le RGO est très fréquent chez le nourrisson, avec un pic vers 4 mois. Il est le plus souvent physiologique, en raison d'une alimentation lactée importante et d'une relaxation inappropriée du sphincter inférieur de l'oesophage. Évoquer un RGO pathologique n'est pas toujours évident, car ses symptômes ont une mauvaise spécificité (pleurs, irritabilité, régurgitations). En revanche, il ne faut pas passer à côté de signes d'alarme évocateurs d'un RGO compliqué par une oesophagite ou par des infections respiratoires hautes ou ORL récidivantes, ni négliger les diagnostics différentiels (allergie aux protéines du lait de vache, oesophagite à éosinophiles, malformations congénitales ou tumeurs cérébrales...). Le diagnostic de RGO est clinique, mais certains examens complémentaires peuvent parfois être discutés : endoscopie oesogastroduodénale, pH-métrie des 24 heures, transit oesogastroduodénal. Il convient de bien expliquer aux parents les mécanismes du RGO et de prendre en charge sa forme physiologique par des mesures non médicamenteuses (adaptation des prises/volumes de lait, épaississants). En l'absence d'amélioration, une éviction des protéines du lait de vache peut être proposée pendant deux à quatre semaines, voire un traitement par inhibiteurs de la pompe à protons.

Pediatric endoscopy training across Europe: a survey of the ESPGHAN National Societies Network 2016-2019.

Background and study aims The ability to perform endoscopy procedures safely and effectively is a key aspect of quality clinical care in Pediatric Gastroenterology, Hepatology and Nutrition (PGHN). The aim of this survey, which was part of a global survey on PGHN training in Europe, was to assess endoscopy training opportunities provided across Europe. Methods Responses to standardized questions related to endoscopy training were collected from training centers across Europe through the presidents/representatives of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition National Societies from June 2016 to December 2019. Results A total of 100 training centers from 19 countries participated in the survey. In 57 centers, the endoscopy suit was attached to the PGHN center, while in 23, pediatric endoscopies were performed in adult endoscopy facilities. Ninety percent of centers reported the availability of specialized endoscopy nurses and 96 % of pediatric anesthetists. Pediatric endoscopies were performed by PGHN specialists in 55 centers, while 31 centers reported the involvement of an adult endoscopist and 14 of a pediatric surgeon. Dividing the number of procedures performed at the training center by the number of trainees, ≤ 20 upper, lower, or therapeutic endoscopies per trainee per year were reported by 0 %, 23 %, and 56 % of centers, respectively, whereas ≤ 5 wireless capsule endoscopies per trainee per year by 75 %. Only one country (United Kingdom) required separate certification of competency in endoscopy. Conclusions Differences and deficiencies in infrastructure, staffing, and procedural volume, as well as in endoscopy competency assessment and certification, were identified among European PGHN training centers limiting training opportunities in pediatric endoscopy.

Training in pediatric neurogastroenterology and motility across Europe: a survey of the ESPGHAN National Societies Network 2016-2019.

Background: Pediatric gastrointestinal motility disorders present significant challenges for diagnosis and management, emphasizing the need for appropriate training in Pediatric Neurogastroenterology and Motility (PNGM). The aim of this survey, part of a comprehensive survey on training in pediatric gastroenterology, hepatology and nutrition, was to evaluate training related to PNGM across European training centers. Method: Standardized questionnaires were collected from training centers through the National Societies Network of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN), from June 2016 to December 2019. Results: In total, 100 training centers from 19 countries participated in the survey. Dedicated PNGM clinics were available in 22 centers; pH-monitoring in 60; pH/impedance in 66; standard manometry in 37; and high-resolution manometry in 33. If all motility studies were performed partially or fully by the trainees, the median (range) annual numbers/per trainee were as follows: pH-monitoring 30 (1-500); pH/impedance 17 (1-131); standard manometries 10 (1-150); and high-resolution manometries 8 (1-75). The motility assessment was performed by pediatric gastroenterologists (43 centers); adult gastroenterologists (10 centers); pediatric surgeons (5 centers); and both pediatric gastroenterologists and pediatric surgeons (9 centers). Annual numbers ≤10 for pH-monitoring, pH/impedance, standard manometries and high-resolution manometries were reported by 7 (12%), 15 (23%), 11 (30%) and 14 (42%) centers, respectively. Conclusions: Significant differences exist in PNGM-related infrastructure, staff and procedural volumes at training centers across Europe. ESPGHAN and the National Societies should take initiatives to ensure the acquisition of competence in PNGM-related knowledge and skills, and develop strategies for assessment and accreditation.An infographic is available for this article at: http://www.annalsgastro.gr/files/journals/1/earlyview/2022/Infographic-AG6486.pdf.

Association of training standards in pediatric gastroenterology, hepatology and nutrition in European training centers with formal national recognition of the subspecialty: a survey of the ESPGHAN National Societies Network 2016-2019.

Background: This survey evaluated the effects of the recognition of pediatric gastroenterology, hepatology and nutrition (PGHN) on European PGHN training centers. Method: Standardized questionnaires were collected from training centers via the presidents/representatives of the National Societies Network of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition, from June 2016 to December 2019. Results: A total of 100 training centers from 19 countries participated in the survey: 55 from 12 countries where PGHN is formally recognized (Group 1) and 45 from 7 countries where it is not (Group 2). Training centers in Group 2 were less likely to have an integrated endoscopy suite, a written training curriculum and a training lead (P=0.059, P<0.001 and P=0.012, respectively). Trainees in Group 2 were less likely to be exposed to an adequate number of diagnostic endoscopies, while no differences were found in relation to liver biopsies. Half of the training centers in both Groups do not have dedicated beds for PGHN patients, while in 64% and 58%, respectively, trainees do not participate in on-call programs for PGHN emergencies. Research training is mandatory in 26% of the centers. The duration of training, as well as the assessment and accreditation policies, vary between countries. Conclusions: This study has revealed significant discrepancies and gaps in infrastructure and training programs, training leadership, and assessment of training and certification across European training centers in PGHN. Strategies to support the recognition of PGHN and to standardize and improve training conditions should be developed and implemented.An infographic is available for this article at: http://www.annalsgastro.gr/files/journals/1/earlyview/2022/Infographic_AG-6496.pdf.

Training in pediatric hepatology across Europe: a survey of the National Societies Network (2016-2019) of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition.

Background: The widely recognized burden of liver diseases makes training in pediatric hepatology (PH) imperative. The aim of this survey, which was part of a global survey on training in pediatric gastroenterology, hepatology and nutrition (PGHN) across Europe, was to assess the PH and liver transplantation (LT) infrastructure, staff and training programs in PGHN training centers. Method: Standardized questionnaires were collected from training centers via the presidents/representatives of the National Societies Network of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) from June 2016 to December 2019. Results: A total of 100 PGHN training centers participated in the survey (14/100 were national referral centers in PH and/or LT). Dedicated PH clinics were available in 75%, but LT clinics in only 11%. Dedicated beds for PGHN inpatients were available in 47/95 (49%) centers. Full-time or part-time specialists for PH care were available in 31/45 (69%) and 11/36 (31%) centers, respectively. Liver biopsies (LB) were performed in 93% of centers by: a PGHN specialist (35%); an interventional radiologist (26%); a pediatric surgeon (4%); or a combination of them (35%). Dividing the annual number of LBs in the centers performing LBs by the number of trainees gave a median (range) of 10 (1-125) per trainee. Transient elastography was available in 60/92 (65%) of centers. Conclusions: The survey highlighted the differences and shortcomings in PH training across Europe. ESPGHAN should take initiatives together with National Societies to ensure the acquisition of PH knowledge and skills according to the ESPGHAN curriculum.An infographic is available for this article at: http://www.annalsgastro.gr/files/journals/1/earlyview/2022/Infographic-Hepatology-training-paper.pdf.

Congenital disorders of intestinal digestion and absorption (sugars, proteins, lipids, ions).

Congenital diarrhea may result from 2 main different mechanisms: 1) osmotic diarrhea is caused by the non-digestion-absorption of nutrients leading to the non-absorbed nutrients going into the lumen, increasing the osmotic force and driving fluids; 2) secretory diarrhea induced by the inhibition of intestinal absorption of electrolytes, increasing electrolyte and water flux towards the intestinal lumen. The malabsorption of macronutrients (carbohydrates, proteins and lipids) induces energy deficiency with symptoms depending on the macronutrient: carbohydrates with watery acidic diarrhea; protein with rapid malnutrition, edema, and hypoalbuminemia; and lipids with malnutrition, steatorrhea and hypocholesterolemia. Ionic malabsorption (Cl and Na) is responsible for severe and rapid dehydration sometimes with prenatal abnormalities (polyhydramnios and bowel dilatation).

Porto-Sinusoidal Vascular Disease: A Pediatric Study of 30 Patients.

OBJECTIVES: Porto-sinusoidal vascular disease (PSVD) refers to a broad spectrum of histological lesions and phenotypic expressions. There are only a few reported pediatric cases in the literature. The primary outcomes of this study were to describe the phenotype of children with PSVD, to specify their mode of presentation and their clinical, biological, histological, and radiological characteristics as well as to identify their underlying etiologies. METHODS: This is a descriptive, retrospective, and monocentric study of children followed at our reference center for rare vascular liver diseases. RESULTS: Our study included 30 children ages 2months to 17.4years at the time of diagnosis. in most cases, the diagnosis was made incidentally without manifestation of any clinical symptom but rather on the finding of splenomegaly on physical examination (n = 9) or biological abnormalities (n = 13). In the other cases, the main presenting symptom was an upper gastrointestinal bleeding (n = 6). At the first visit, liver laboratory values were either normal (37%) or slightly disturbed. Anemia and/or thrombocytopenia associated with hypersplenism were found in 60% of patients. Liver biopsy was necessary for diagnosis. A total of 80% of cases had no identified etiology. After a median follow-up of 4.5 years, 33% had not developed portal hypertension (PHT) and we reported the first pediatric case of hepatocellular carcinoma in PSVD children. CONCLUSIONS: PSVD is responsible for nonspecific symptomatology with variable evolution sometimes marked by serious complications requiring invasive treatments or even liver transplantation. Regular monitoring is essential to prevent, detect, and treat complications.

Training in Paediatric Clinical Nutrition Across Europe: A Survey of the National Societies Network (2016-2019) of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition.

OBJECTIVES/BACKGROUND: Disease-related malnutrition is common in patients with chronic diseases and has detrimental effects, therefore, skills in nutrition care are essential core competencies for paediatric digestive medicine. The aim of this survey, conducted as part of a global survey of paediatric gastroenterology, hepatology and nutrition (PGHN) training in Europe, was to assess nutrition care-related infrastructure, staff, and patient volumes in European PGHN training centres. METHODS: Standardized questionnaires related to clinical nutrition (CN) care were completed by representatives of European PGHN training centres between June 2016 and December 2019. RESULTS: One hundred training centres from 17 European countries, Turkey, and Israel participated in the survey. Dedicated CN clinics exist in 66% of the centres, with fulltime and part-time CN specialists in 66% and 42%, respectively. Home tube feeding (HTF) andhome parenteral nutrition (HPN) programmes are in place in 95% and 77% of centres, respectively. Twenty-four percent of centres do not have a dedicated dietitian and 55% do not have a dedicated pharmacist attached to the training centre. Even the largest centres with >5000 outpatients reported that 25% and 50%, respectively do not have a dedicated dietitian or pharmacist. Low patient numbers on HTF and HPN of <5 annually are reported by 13% and 43% of centres, respectively. CONCLUSIONS: The survey shows clear differences and deficits in Clinical Nutrition training infrastructure, including staff and patient volumes, in European PGHN training centres, leading to large differences and limitations in training opportunities in Clinical Nutrition.

Helicobacter pylori-negative Chronic Gastritis in Children: A Systematic Review.

OBJECTIVES: To systematically review the current evidence on Helicobacter pylori-negative chronic gastritis including natural history, available therapies and outcomes. METHODS: Articles providing data on the prevalence, treatment or outcomes of Helicobacter pylori-negative gastritis were identified through a systematic search in the MEDLINE and EMBASE databases. All original research articles from human studies until October 31, 2021, were included. RESULTS: A total of 54 studies were included consisted of eosinophilic gastritis (n = 9), autoimmune gastritis (n = 11), collagenous gastritis (n = 16), focally enhanced gastritis (n = 6), lymphocytic gastritis (n = 5) and other causes including idiopathic gastritis and chronic renal failure related (n = 7). Most of the included studies were either cross-sectional or longitudinal cohorts except for collagenous gastritis, which mainly included case reports and case series. The prevalence of paediatric eosinophilic gastritis ranges between 5 and 7/100,000 and patients have generally favourable outcome with 50% to 70% clinical and histological response to either corticosteroids or elimination diets. Autoimmune gastritis and collagenous gastritis are extremely rare entities, commonly present with refractory iron deficiency anaemia, while lymphocytic gastritis is relatively common (10%-45%) in children with coeliac disease. Data on treatments and outcomes of autoimmune, collagenous, and focally enhanced gastritis are lacking with limited data implying poor response to therapy in the former 2 diagnoses. CONCLUSIONS: Helicobacter pylori-negative gastritis is uncommonly reported, mainly in small cohorts, mixed adult-paediatric cohorts or as sporadic case reports. As common symptoms are not specific, thus not always result in an endoscopic evaluation, the true prevalence of these distinct disorders may be underestimated, and thus under reported.

Drugs in Focus: Octreotide Use in Children With Gastrointestinal Disorders.

ABSTRACT: Octreotide, a somatostatin analogue, has been used for more than 20 years in children with gastrointestinal bleeding, chylothorax or chylous ascites, intestinal lymphangiectasia, pancreatitis, intestinal dysmotility, and severe diarrhoea; however, until now, there is a lack of randomised clinical trials evaluating the efficacy of this compound in childhood. Hence, we aimed to review the literature in order to determine the evidence of its use and safety in children, using PubMed from 2000 to 2021 with the search terms "octreotide" and "children" and "bleeding or chylous ascites or chylothorax or acute pancreatitis or lymphangiectasia or diarrhoea or intestinal dysmotility".
