Objectives: Celiac disease (CeD) requires long-term follow. The role of laboratory testing other than celiac serology during follow up is unclear. We aimed to determine which laboratory tests are required during follow up based on the prevalence of abnormal tests and timing of abnormalities appearance., Methods: Retrospective chart-review of children diagnosed with CeD between 1999 and 2018 was conducted. Demographic, clinical and laboratory data were recorded from diagnosis and during follow-up., Results: The cohort included 500 children with CeD [59.8% females, median(IQR) age at diagnosis 5.7(3.7-8.9) years]. Mean follow-up time was 5.5 years (range 1.5-16.2). The most frequently abnormal laboratory tests at time of diagnosis were low ferritin (64.3%), vitamin D (33.6%), zinc (29.9%), hemoglobin (29.2%), and folate (14.7%). In 74 (14.8%) patients, anemia developed only during follow up, while in another 46 patients, anemia resolved after diagnosis and reappeared later (after a mean ± SD 2.8 ± 2.1 years from CeD diagnosis, for the entire group). Abnormal values that developed during follow up were low folate in 40 patients (3.9 ± 2.6 years), and abnormal liver enzymes in 18 patients (3.1 ± 2.7 years). Elevated TSH during follow-up was observed in 14/280 (5%) patients, after a mean ± SD of 2.2 ± 1.6 years from diagnosis. Patients diagnosed as teenagers (12-18 years) had shorter intervals to reappearance of anemia and folate deficiency., Conclusions: Multiple laboratory abnormalities may occur in pediatric patients with CeD, both at diagnosis and during long-term follow-up. We suggest continued monitoring of hemoglobin, ferritin, folate, liver, and thyroid function in addition to celiac serology during follow-up of CeD., (© 2025 The Author(s).

In April 2022, an increased incidence of acute hepatitis cases of unknown etiology among previously healthy children across the United Kingdom was described. Since, more than 270 cases from the United Kingdom and hundreds more from all across the world have been reported. The majority of affected children were younger than 6 years of age. The clinical presentation was nonspecific with diarrhea and vomiting usually preceding the appearance of jaundice, abdominal pain, nausea, and malaise. Approximately 5% have required liver transplantation. An infectious etiology has been considered likely given the epidemiological and clinical features of the reported cases. Between 50 and 60% of the children tested were diagnosed with adenovirus infection although a clear etiological connection has still to be demonstrated. No link with SARS-CoV-2 infection and COVID-19 vaccine was found. What is not clear to date is whether the high number of acute hepatitis cases reported is related to a true increase in incidence or heightened awareness following on from the initial reports from the United Kingdom. The Hepatology Committee of the European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) developed a paper on the current outbreak of acute hepatitis of unknown etiology recognizing its importance and the need of approaching the current situation with a scientifically rigorous approach. The aims of the article are to summarize the current knowledge and to identify the most pertinent issues regarding the diagnosis and management of this condition and the research questions raised., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 by European Society for European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: Severe acute respiratory syndrome coronavirus 2, the novel coronavirus responsible for coronavirus disease (COVID-19), has been a major cause of morbidity and mortality worldwide. Gastrointestinal and hepatic manifestations during acute disease have been reported extensively in the literature. Post-COVID-19 cholangiopathy has been increasingly reported in adults. In children, data are sparse. Our aim was to describe pediatric patients who recovered from COVID-19 and later presented with liver injury., Methods: This is a retrospective case series study of pediatric patients with post-COVID-19 liver manifestations. We collected data on demographics, medical history, clinical presentation, laboratory results, imaging, histology, treatment, and outcome., Results: We report 5 pediatric patients who recovered from COVID-19 and later presented with liver injury. Two types of clinical presentation were distinguishable. Two infants aged 3 and 5 months, previously healthy, presented with acute liver failure that rapidly progressed to liver transplantation. Their liver explant showed massive necrosis with cholangiolar proliferation and lymphocytic infiltrate. Three children, 2 aged 8 years and 1 aged 13 years, presented with hepatitis with cholestasis. Two children had a liver biopsy significant for lymphocytic portal and parenchyma inflammation, along with bile duct proliferations. All 3 were started on steroid treatment; liver enzymes improved, and they were weaned successfully from treatment. For all 5 patients, extensive etiology workup for infectious and metabolic etiologies was negative., Conclusions: We report 2 distinct patterns of potentially long COVID-19 liver manifestations in children with common clinical, radiological, and histopathological characteristics after a thorough workup excluded other known etiologies., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 by European Society for European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: Severe obesity in the pediatric population has lifelong consequences. Bariatric surgery has been suggested for selected adolescents with severe obesity after careful evaluation. The indications for preoperative esophagogastroduodenoscopy (EGD) in this age group are not clear, despite its established usefulness in adults. We aimed to assess the usefulness of EGD before bariatric surgery in pediatric patients with severe obesity and metabolic comorbidities., Methods: We conducted a retrospective chart review in a single tertiary pediatric medical center of adolescents treated during 2011 to 2018. Data collected from electronic medical records included patient demographics, endoscopic findings, and laboratory parameters., Results: A total of 80 patients (40 boys) underwent evaluation. Macroscopic abnormalities were detected in 54% of the endoscopies, including gastritis, esophagitis, and duodenitis in 46%, 16%, and 13%, respectively. Forty-nine percentage of the biopsies showed histological abnormalities; in 35 (44%) patients, Helicobacter pylori was detected. Thirty-three patients (41%) received medical treatment and 2 (2.5%) required a second EGD. Metabolic comorbidities included hypertriglyceridemia (38% of the patients), low high-density lipoprotein (23%), and prediabetic (16%) or diabetic levels of HbA1C (4%). Fifty-five percentage of the cohort had elevated alanine aminotransferase (ALT), suggestive of nonalcoholic fatty liver disease (NAFLD)., Conclusions: Endoscopies performed before bariatric surgeries suggest a higher prevalence of clinically significant findings, many of which required treatment. These findings support incorporating an EGD into the preoperative evaluation of this patient population., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: Celiac disease (CD) is a common intestinal autoimmune disorder with diverse presenting features. We aimed to determine age-dependent patterns in CD presentation, diagnosis and management at a large tertiary referral center., Methods: A retrospective review of electronic medical records of pediatric patients diagnosed with CD between January 1999 and December 2018 at Schneider Children's Medical Center of Israel. We compared demographics, clinical and laboratory parameters between four age groups at CD presentation., Results: A cohort of 932 children was divided into four groups by age (in years) at diagnosis: 0-3 (17.9%), 3-6 (31.8%), 6-12 (34.5%), 12-18 (15.8%). The youngest age group presented more frequently with diarrhea, weight loss, abdominal distention, vomiting and lower weight z scores, P < 0.01. Hypoalbuminemia and zinc deficiency were also more frequent in this age group, compared to older patients (P < 0.05, each). Rates of anemia were higher in younger age groups (0-3 and 3-6 years), compared to older age groups, P < 0.05. Patients in the younger age groups (0-3 and 3-6 years) presented more frequently with tissue transglutaminase (TTG) levels above 10 times the upper limit of normal (ULN; P < 0.05), and more often normalized their CD serologies by 24 months of gluten-free diets (GFD) compared to older age groups (P < 0.05)., Conclusion: There is an age-dependent variation in CD presentation during childhood. Younger patients present more often with malabsorptive features, and higher TTG levels, yet normalize TTG while on GFD more rapidly than older patients. Clinicians should be aware of the diversity in CD presentation and course at the various presentation age., Competing Interests: The authors report no conflict of interests., (Copyright © 2021 by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: Diet assessment is essential in the care of patients with inflammatory bowel disease (IBD). We aimed to study food intake in children with IBD and evaluated the relation of dietary intake with disease activity and nutritional status in these children., Methods: This cross-sectional study investigated 68 children and adolescents with IBD (57 Crohn disease, 11 ulcerative colitis). Evaluation included clinical, laboratory, and nutritional assessment including 3 days diet record., Results: Compared with recommended daily allowance, the intake of patients with IBD was significantly poor for carbohydrates (75%, P = 0.016), calcium (49%, P < 0.05), magnesium (76%, P < 0.05), vitamin A (72%, P < 0.05), vitamin E (57%, P < 0.05), and fiber (44%, P < 0.05) and higher for protein (175%, P < 0.05), iron (112%, P < 0.05), and water-soluble vitamins (118%-189% P < 0.05). Compared with the intakes of healthy children from National Nutritional Survey, the intake of IBD group was lower for calories (78%, P = 0.012), carbohydrates (61% P < 0.05), magnesium (67% P < 0.05), vitamin C (34%, P < 0.05), and fiber (54%, P < 0.05) and high for B12 (141%, P < 0.05). Fifty subjects ate ordinary diets, 7 of 68 children were on exclusive enteral nutrition and 11 of 68 consumed regular food with different polymeric formulas supplements. Compared with children without supplements, children on exclusive enteral nutrition and nutritional supplements (18/68) had significantly better intakes of energy (1870 ± 755 vs 2267 ± 432, P < 0.05), carbohydrates (223 ± 97 vs 292 ± 99, P < 0.05), and all minerals (P < 0.05) and micronutrients (P < 0.05). Dietary intake was not different by disease status (remission or relapse)., Conclusions: In the absence of nutritional supplements, food intake is inadequate for many nutrients in many children with IBD.
