Health-related quality of life in children with coeliac disease and in their families: A long-term follow-up study.

OBJECTIVES: The aim of the study was to assess long-term health-related quality of life (HRQoL) in children and adolescents with coeliac disease (CD), and their parents. METHODS: We re-evaluated prospectively the HRQoL and clinical characteristics of 80 families, assessed 5 years earlier, using a disease-specific questionnaire, the CD Dutch Questionnaire (CDDUX), and a generic questionnaire, the Paediatric Quality of Life Inventory (PedsQL). RESULTS: After a 10-year follow-up, there was no significant change in the total CDDUX and PedsQL scores in children and their parents when compared to the evaluation conducted 5 years earlier. The total CDDUX score reflected a neutral QoL, while for the generic PedsQL was good-very good. The only significant decrease after 5 years was the PedsQL subdomain Emotional functioning. Patients who admitted voluntarily eating gluten reported lower score in CDDUX Diet. Lower scores in subdomain "Physical functioning" (PedsQL) were reported in patients with positivity of TTG or associated diseases. CONCLUSIONS: The CDDUX score indicated a consistently stable and neutral QoL perception among coeliac patients and caregivers, even after 10-year postdiagnosis, suggesting minimal fluctuations in the impact of CD on disease-specific health domains over time. Furthermore, the consistently good PedsQL score could be a reflection of the resilience of coeliac families in coping with this chronic condition. Gluten-free diet compliance was confirmed to be determinant of HRQoL in the long term. The study confirms the importance of extending surveillance on these patients, possibly using different questionnaires, to assess QoL from different perspectives.

Pediatric nutritional surgery and its implications: results from a unicentric retrospective analysis.

PURPOSE: Existing guidelines provide weak recommendations on the surgical management of nutritional problems in children. The objective was to design a management pathway to address the best nutritional surgery (NS) procedure in a given patient. METHODS: Retrospective analysis of children treated at our department from January 2015 to December 2019. The sample was divided into two groups according to presence or absence of neurological impairment (NI). Patients with NI (Group 1) were classified in three subgroups based on presenting symptoms: A-Dysphagia without gastroesophageal reflux (GER); B-GER with or without dysphagia; C-Symptoms associated with a delayed gastric emptying. RESULTS: A total of 154 patients were included, 111 with NI. One-hundred-twenty-eight patients underwent only one procedure. Complications and mortality were superior in Group 1. In subgroup A, isolated gastrostomy was the first NS in all patients. In subgroup B most of patients were subjected to a Nissen fundoplication, while in 5 cases total esophagogastric dissociation (TEGD) was the first intervention. Considering the entire sample, 92.3% patients who underwent a TEGD did not require further procedures. CONCLUSION: NS encompasses various procedures depending on presenting symptoms and neurological status. A management flowchart for these patients is proposed.

Clinical Course of Very Early-Onset Inflammatory Bowel Disease.

OBJECTIVES: Data on the phenotypes and disease outcomes of very early-onset inflammatory bowel disease (VEO-IBD) are limited. The aims of this study were to describe the clinical features, outcomes, and treatment response of VEO-IBD patients and to compare them with later-onset pediatric inflammatory bowel disease (P-IBD) patients. METHODS: All consecutive patients aged 0-6 years who were diagnosed with Crohn disease (CD), ulcerative colitis, or IBD unclassified (IBD-U) at 2 academic hospitals from 2010 to March 2021 were included. They were compared to sex-matched IBD patients aged 6-17 years. RESULTS: Two hundred thirty-two patients were included, 78 (34%) with VEO-IBD and 154 (66%) with P-IBD. IBD-U was the most common diagnosis in the VEO-IBD group compared to P-IBD (28% vs 3%, P < 0.001), while CD was predominant in older children (27% vs 52%, P < 0.001). The VEO-IBD group showed lower rates of clinical remission after induction with steroids compared to older children (82% vs 93%, P = 0.01), higher rates of steroid resistance (14% vs 5%, P = 0.02), and steroid dependence (27% vs 8%, P < 0.001). The number of patients who started anti-tumor necrosis factor (TNF)-α agents was similar between the groups. Anti-TNF-α retention was lower in the VEO-IBD group at 1 and 2 years (59% vs 85%, P = 0.003; 16% vs 55%, P < 0.001, respectively). Surgical risk appeared to be higher for VEO-IBD (32% vs 14%, P < 0.001). CONCLUSIONS: When compared to P-IBD patients, patients with VEO-IBD may have a more severe disease course, a poorer response to steroids and anti-TNF-α agents, and require more frequent surgical procedures.

Multi-disciplinary Insights from the First European Forum on Visceral Myopathy 2022 Meeting.

Visceral myopathy is a rare, life-threatening disease linked to identified genetic mutations in 60% of cases. Mostly due to the dearth of knowledge regarding its pathogenesis, effective treatments are lacking. The disease is most commonly diagnosed in children with recurrent or persistent disabling episodes of functional intestinal obstruction, which can be life threatening, often requiring long-term parenteral or specialized enteral nutritional support. Although these interventions are undisputedly life-saving as they allow affected individuals to avoid malnutrition and related complications, they also seriously compromise their quality of life and can carry the risk of sepsis and thrombosis. Animal models for visceral myopathy, which could be crucial for advancing the scientific knowledge of this condition, are scarce. Clearly, a collaborative network is needed to develop research plans to clarify genotype-phenotype correlations and unravel molecular mechanisms to provide targeted therapeutic strategies. This paper represents a summary report of the first 'European Forum on Visceral Myopathy'. This forum was attended by an international interdisciplinary working group that met to better understand visceral myopathy and foster interaction among scientists actively involved in the field and clinicians who specialize in care of people with visceral myopathy.

Novel ACTG2 variants disclose allelic heterogeneity and bi-allelic inheritance in pediatric chronic intestinal pseudo-obstruction.

Variants in the ACTG2 gene, encoding a protein crucial for correct enteric muscle contraction, have been found in patients affected with chronic intestinal pseudo-obstruction, either congenital or late-onset visceral myopathy, and megacystis-microcolon-intestinal hypoperistalsis syndrome. Here we report about ten pediatric and one adult patients, from nine families, carrying ACTG2 variants: four show novel still unpublished missense variants, including one that is apparently transmitted according to a recessive mode of inheritance. Four of the remaining five probands carry variants affecting arginine residues, that have already been associated with a severe phenotype. A de novo occurrence of the variants could be confirmed in six of these families. Since a genotype-phenotype correlation is affected by extrinsic factors, such as, diagnosis delay, quality of clinical management, and intra-familial variability, we have undertaken 3D molecular modeling to get further insights into the effects of the variants here described. The present findings and further ACTG2 testing of patients presenting with intestinal pseudo-obstruction, will improve our understanding of visceral myopathies, including implications in the prognosis and genetic counseling of this set of severe disorders.

Thalidomide as treatment of crohn-like disease occurred after allogeneic hematopoietic stem cell transplantation in a pediatric patient.

BACKGROUND: Autoimmune diseases may occur after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and inflammatory bowel disease (IBD or Crohn disease) is rarely described. We describe a child who developed CD after allo-HSCT, successfully treated with thalidomide. CASE REPORT: A child affected by mucopolysaccharidosis type I received two allogeneic HSCTs for rejection after the first one. After cutaneous and intestinal chronic GvHD and 6 months after HSCT, the patients developed a trilinear autoimmune cytopenia successfully treated with rituximab and sirolimus. Due to persisting intestinal symptoms, colonoscopies were performed and histological findings demonstrated a picture of CD. Based on this observation and according to the recommendations for the treatment of CD, thalidomide was started. A complete stable clinical response was obtained 8 weeks after start of thalidomide. Colonoscopy performed 4.8 years later demonstrated a complete endoscopic and histological remission of CD. DISCUSSION: In this case, the diagnosis of CD after HSCT was based on histological findings. Indeed, repeated colonscopies were necessary for diagnosis, since both clinical and endoscopic features are often common to chronic GvHD and CD. Thalidomide was started at the dose of 1.7 mg/Kg/day, and it was well tolerated. Mild peripheral neurotoxicity occurred 5 years later but disappeared completely with the dose reduction. Currently, the patient is in complete remission from CD, despite the discontinuation of all the immunosuppressive therapies. CONCLUSIONS: Thalidomide could represent a therapeutic option to treat CD as autoimmune disease after allogeneic HSCT.

Epileptic Encephalopathy, Myoclonus-Dystonia, and Premature Pubarche in Siblings with a Novel C-Terminal Truncating Mutation in ATRX Gene.

The X-linked alpha thalassemia mental retardation (ATR-X) syndrome is a genetic disorder caused by X-linked recessive mutations in ATRX gene, related to a wide spectrum of clinical manifestations, such as alpha thalassemia, developmental delay, genital abnormalities, and gastrointestinal disorders. Patients with ATR-X syndrome can suffer from different types of epileptic seizures, but a severe epileptic encephalopathy pattern has not been described to date. We describe, for the first time, two brothers with genetically confirmed ATR-X syndrome who presented with drug-resistant epileptic encephalopathy, with tonic and polimorphic seizures reported in the elder brother and epileptic spasms in the younger brother. Moreover, both brothers showed a peculiar movement disorder with myoclonus-dystonia, worsened during periods of distress or pain. These cases expand the clinical spectrum of ATR-X syndrome and open new opportunities for the molecular diagnosis of ATRX mutations in male patients with severe epileptic encephalopathies and movement disorders.

Octreotide for congenital and acquired chylothorax in newborns: A systematic review.

AIM: Chylothorax is a rare but life-threatening condition in newborns. Octreotide, a somatostatin analogue, is widely used as a therapeutic option in neonates with congenital and acquired chylothorax, but its therapeutic role has not been clarified yet. METHODS: We performed a systematic review to assess the efficacy and safety of octreotide in the treatment of congenital and acquired chylothorax in newborns. Comprehensive research, updated till 31 October 2017, was performed by searching in PubMed, MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) databases using the MeSH terms 'octreotide' and 'chylothorax'. Both term and preterm newborns with congenital or acquired chylothorax treated with octreotide within the 30th day of life were included. Octreotide treatment was considered effective if a progressive reduction/ceasing in drained chylous effusion occurred. RESULTS: A total of 39 articles were included. Octreotide was effective in 47% of patients, with a slight but not significant difference between congenital (30/57; 53.3%) and acquired (9/27; 33.3%) chylothorax (P = 0.10). Marked variation in octreotide regimen was observed. The most common therapeutic scheme was intravenous infusion at a starting dose of 1 µg/kg/h, gradually increasing to 10 µg/kg/h according to the therapeutic response. Side effects were reported in 12 of 84 patients (14.3%). Only case reports were included in this review due to the lack of randomised controlled trials. CONCLUSION: Octreotide is a relatively effective and safe treatment option in neonates with chylothorax, especially for the congenital forms.

Morbidity and Risk Factors of Laparoscopic-Assisted Ileostomies in Children With Ulcerative Colitis.

INTRODUCTION: Laparoscopic-assisted ileostomy (LAI) represents a cornerstone for the staged approach to ulcerative colitis (UC). The aim is to determine stoma morbidity in a series of pediatric patients and possibly identify specific risk factors. METHODS: All of the patients who underwent LAI for UC between January 2008 and December 2014 were included. The following data were collected: patient demographics, preoperative medical treatment, body mass index (BMI) at surgery, Pediatric UC Index (PUCAI), and stoma-related complications. In this series of patients, a staged approach has been adopted (subtotal colectomy + ileostomy; restorative proctocolectomy with J-pouch ileo-rectal anastomosis + ileostomy; ileostomy closure). RESULTS: Seventy-two LAIs were fashioned in 37 pediatric patients with UC. Median age at surgery was 12 years (range 5-14.8 years). Boy to girl ratio was 0.85:1. Mortality was zero. Complications occurred after 8 procedures after a median of 31 days postoperatively (range 8-60 days). Those were significantly more frequent in the case of BMI-z score >-0.51 (deleted in revised manuscript, ie, relatively overweight patients) and in the case of preoperative azathioprine administration. Pediatric UC Index score, sex, number of preoperative medications, and other preoperative parameters did not correlate with the incidence of complications. CONCLUSIONS: Our study suggests to keep a prudent behavior in the case of patients with a BMI-z score >-0.51 and received preoperative azathioprine administration. Parents should be adequately acknowledged on this regard.

Long-term outcome and need of re-operation in gastro-esophageal reflux surgery in children.

BACKGROUND: Fundoplication is considered a mainstay in the treatment of gastro-esophageal reflux. However, the literature reports significant recurrences and limited data on long-term outcome. AIMS: To evaluate our long-term outcomes of antireflux surgery in children and to assess the results of redo surgery. METHODS: We retrospectively analyzed all patients who underwent Nissen fundoplication in 8 consecutive years. Reiterative surgery was indicated only in case of symptoms and anatomical alterations. A follow-up study was carried out to analyzed outcome and patients' Visick score assessed parents' perspective. RESULTS: Overall 162 children were included for 179 procedures in total. Median age at first intervention was 43 months. Comorbidities were 119 (73 %), particularly neurological impairments (73 %). Redo surgery is equal to 14 % (25/179). Comorbidities were risk factors to Nissen failure (p = 0.04), especially children suffering neurological impairment with seizures (p = 0.034). Follow-up datasets were obtained for 111/162 = 69 % (median time: 51 months). Parents' perspectives were excellent or good in 85 %. CONCLUSIONS: A significant positive impact of redo Nissen intervention on the patient's outcome was highlighted; antireflux surgery is useful and advantageous in children and their caregivers. Children with neurological impairment affected by seizures represent significant risk factors.

Diagnostic accuracy of upper gastrointestinal series in children with suspected intestinal malrotation.

Intestinal malrotation (IM) results from an altered or incomplete rotation of the fetal midgut around the superior mesenteric artery axis. The abnormal anatomy of IM is associated with risk of acute midgut volvulus which can lead to catastrophic clinical consequences. The upper gastro-intestinal series (UGI) is addressed as the gold standard diagnosis procedure, but a variable failure degree has been described in literature. The aim of the study was to analyze the UGI exam and describe which features are the most reproducible and reliable in diagnosing IM. Medical records of patients surgically treated for suspected IM between 2007 and 2020 at a single pediatric tertiary care center were retrospectively reviewed. UGI inter-observer agreement and diagnostic accuracy were statistically calculated. Images obtained with antero-posterior (AP) projections were the most significant in terms of IM diagnosis. Duodenal-Jejunal Junction (DJJ) abnormal position resulted to be the most reliable parameter (Se = 0.88; Sp = 0.54) as well as the most readable, with an inter-reader agreement of 83% (k = 0.70, CI 0.49-0.90). The First Jejunal Loops (FJL), caecum altered position and duodenal dilatation could be considered additional data. Lateral projections demonstrated an overall low sensitivity (Se = 0.80) and specificity (Sp = 0.33) with a PPV of 0.85 and a NPV of 0.25. UGI on the sole AP projections ensures a good diagnostic accuracy. The position of the third portion of the duodenum on lateral views showed an overall low reliability, therefore it was not helpful but rather deceiving in diagnosing IM.

Non-interventional, 5-year retrospective data of home parenteral nutrition in patients with benign chronic intestinal failure: Analysis of an Italian nurse registry (SERECARE II).

OBJECTIVE: This study is an assessment of home parenteral nutrition service performance and safety and efficacy outcomes in patients with benign chronic intestinal failure. METHODS: This is a retrospective, non-interventional, and multicenter study. Data were collected by trained nurses and recorded in a dedicated registry (SERECARE). RESULTS: From January 1, 2013 to June 30, 2018, data from a total of 683 patients with benign chronic intestinal failure were entered in the registry. Patients included 208 pediatric (53.8% male; median age = 4.0 y) and 475 adult (47.6% male; median age = 59.0 y) participants. On average, patients were visited 5.4 ± 4.5 times and received 1.4 ± 0.8 training sessions. Retraining was not common and mostly due to change of therapy or change of caregiver. Of 939 complications, 40.9% were related to the central venous catheter and were mostly infectious (n = 182) and mechanical (n = 187). The rate of infectious and mechanical complications per 1000 catheter days decreased over 5 y (0.30-0.15 and 0.33 -0.19, respectively). The rate of complications per 1000 catheter days and the mean complications per patient were higher in pediatric than in adult patients. The hospitalization rate was 1.01 per patient throughout the study period. These data were similar to those registered in a previous study period (2002-2011) (n = 1.53 per patient). Changes over time in the efficacy variables were mostly small and non-significant. CONCLUSIONS: This study confirms the importance of setting up and maintaining structured registries to monitor and improve home parenteral nutrition care. Safety outcomes have improved over the years, most likely due to the underlying efficient nursing service.

Foreign body ingestion in children: Definition of a nomogram to predict surgical or endoscopic intervention.

BACKGROUND AND AIMS: Foreign body ingestion (FBI) in children requires early identification to prevent adverse outcomes and may necessitate endoscopic or surgical intervention. This study aims to develop a nomogram that identifies children who require urgent surgical or endoscopic intervention by using the patient's medical history and clinical parameters collected at admission. METHODS: This study is a retrospective review (01/2015-12/2020) of a multicenter case series of children admitted for FBI. Data from 5864 records from 24 hospitals in Italy were analyzed. Logistic regression models were used to establish the probability of requiring surgical or endoscopic intervention based on patient history and clinical characteristics. The nomogram representing the results from the multivariable model was reported to examine the propensity for surgery/endoscopy. RESULTS: The study identified a significant association between intervention and various factors, including type of foreign body (blunt: reference category, disk battery (odds ratio OR:4.89), food bolus (OR:1.88), magnets (OR:2.61), sharp-pointed (OR:1.65), unknown (OR:1.02)), pre-existing diseases or conditions (OR 3.42), drooling (OR 10.91), dysphagia (OR 5.58), vomiting (OR 3.30), retrosternal pain (OR 5.59), abdominal pain (OR 1.58), hematemesis (OR 2.82), food refusal/poor feeding (OR 2.99), and unexplained crying (OR 2.01). The multivariable regression model showed good calibration and discrimination ability, with an area under the ROC curve of 0.77. CONCLUSIONS: This study developed the first nomogram to predict the probability of the need for surgical or endoscopic intervention in children with FBI, based on the information collected at admission. The nomogram will aid clinicians in identifying children who require early intervention to prevent adverse outcomes.

The Influence of SARS-CoV-2 Pandemic on the Diagnosis of Celiac Disease and Clinical Practice in Pediatric Gastroenterology.

Celiac disease (CD) has a high prevalence but remains largely underdiagnosed. Although extensive studies have confirmed that children with CD do not have an increased risk of severe COVID-19, public health regulations associated with the SARS-CoV-2 pandemic may have exacerbated this problem. The aim of this study was to assess the effect of SARS-CoV-2 on the number of new-onset CD cases. Additionally, the role of SARS-CoV-2 in autoimmune diseases and its influence on clinical practice in pediatric gastroenterology were briefly reviewed. We described the data from the hospital electronic registry of new-onset CD, during the COVID-19 pandemic and 2 years before. A total of 423 children were diagnosed with CD between March 2018 and February 2022: 228 in the 2-year pre-COVID-19 period and 195 during the pandemic. The number of patients during the COVID-19 pandemic was 14.5% lower than in the previous years. The quarterly comparison of CD diagnoses showed a reduction in all quarters. A reduction in diagnoses during the lockdown and in the following months was evident and not compensated thereafter. This is the first study to evaluate the impact of SARS-CoV-2 on the diagnosis of CD in children. Further studies are necessary to improve the system of biopsy-sparing diagnosis and to evaluate the effect of the diagnostic delay. Special attention should be given to the implementation of telemedicine services.

Dose escalation of adalimumab as a strategy to overcome anti-drug antibodies: A case report of infantile-onset inflammatory bowel disease.

BACKGROUND: Treatment of infantile-onset inflammatory bowel disease (IO-IBD) is often challenging due to its aggressive disease course and failure of standard therapies with a need for biologics. Secondary loss of response is frequently caused by the production of anti-drug antibodies, a well-known problem in IBD patients on biologic treatment. We present a case of IO-IBD treated with therapeutic drug monitoring (TDM)-guided high-dose anti-tumor necrosis factor therapy, in which dose escalation monitoring was used as a strategy to overcome anti-drug antibodies. CASE SUMMARY: A 5-mo-old boy presented with a history of persistent hematochezia from the 10th d of life, as well as relapsing perianal abscess and growth failure. Hypoalbuminemia, anemia, and elevated inflammatory markers were also present. Endoscopic assessment revealed skip lesions with deep colic ulcerations, inflammatory anal sub-stenosis, and deep fissures with persistent abscess. A diagnosis of IO-IBD Crohn-like was made. The patient was initially treated with oral steroids and fistulotomy. After the perianal abscess healed, adalimumab (ADA) was administered with concomitant gradual tapering of steroids. Clinical and biochemical steroid-free remission was achieved with good trough levels. After 3 mo, antibodies to ADA (ATA) were found with undetectable trough levels; therefore, we optimized the therapy schedule, first administering 10 mg weekly and subsequently up to 20 mg weekly (2.8 mg/kg/dose). After 2 mo of high-dose treatment, ATA disappeared, with concomitant high trough levels and stable clinical and biochemical remission of the disease. CONCLUSION: TDM-guided high-dose ADA treatment as a monotherapy overcame ATA production. This strategy could be a good alternative to combination therapy, especially in very young patients.

Novel insect-based child nutrition: the position of the nutritional committee of the Italian society of pediatric gastroenterology, hepatology and nutrition (SIGENP).

BACKGROUND: The European Union (EU) approved the placement on European market of insect-based novel foods. Those foods were defined safe for the consumption for all European population, including children. MAIN BODY: The nutrition committee of the Italian society of Paediatric Hepatology and Nutrition (SIGENP) performed literature research to understand benefits and risk of those use of those NF for Italian children. A special attention was reserved to the European Food Safety Agency (EFSA) reports upon which those novel insect-based were approved. CONCLUSIONS: Based on the current knowledge, despite a possible ecological advantage, the group of expert suggests additional researches before pronouncing on a possible use for children diet, because of insufficient evidence on nutritional benefits and possible food allergies.

Cutaneous Disorders Masking Celiac Disease: Case Report and Mini Review with Proposal for a Practical Clinical Approach.

Celiac disease (CD) is an immune-mediated systemic gluten-related disorder characterized by a wide spectrum of intestinal and extra-intestinal manifestations, including damage to cutaneous and connective tissue. We report a rare case of chronic severe dermatitis involving connective tissue and cutaneous vascular vessels as the main clinical presentation of undiagnosed seronegative gluten disorder. A gluten-free diet dramatically improved the intestinal and cutaneous clinical damage in the patient. Pitfalls and the steps of differential diagnosis are described. We also review the literature regarding studies of CD and connective tissue diseases to extend the knowledge of these rare associations. We propose a practical diagnostic approach in suspected CD in autoimmune cutaneous disorders.

Patient's dermal fibroblasts as disease markers for visceral myopathy.

Visceral myopathy (VSCM) is a rare genetic disease, orphan of pharmacological therapy. VSCM diagnosis is not always straightforward due to symptomatology similarities with mitochondrial or neuronal forms of intestinal pseudo-obstruction. The most prevalent form of VSCM is associates with variants in the gene ACTG2, encoding the protein gamma-2 actin. Overall, VSCM is a mechano-biological disorder, in which different genetic variants lead to similar alterations to the contractile phenotype of enteric smooth muscles, resulting in the emergence of life-threatening symptoms. In this work we analyzed the morpho-mechanical phenotype of human dermal fibroblasts from patients affected with VSCM, demonstrating that they retain a clear signature of the disease when compared with different controls. We evaluated several biophysical traits of fibroblasts, and we show that a measure of cellular traction forces can be used as a non-specific biomarker of the disease. We propose that a simple assay based on traction forces could be designed to provide a valuable support for clinical decision or pre-clinical research.
