RESUMEN
OBJECTIVE: There is no gold standard to assess adherence to gluten-free diet (GFD) among patients with celiac disease (CeD). Gluten immunogenic peptides (GIPs) in urine and stool were suggested as novel markers for evaluating adherence to GFD. Our aim was to assess the presence of GIP in pediatric patients with CeD, and to compare the results with alternative methods for evaluating GFD adherence. METHODS: Pediatric patients diagnosed with CeD, who were on GFD for at least 1 year, were enrolled and followed prospectively between November 2018 and January 2021. Study visits included clinical assessment, a dietitian interview, Biagi score, food questionnaires, anthropometric and laboratory measurements, and urine and stool samples obtained for laboratory GIP analysis. RESULTS: The study included 74 patients (63.5% females), with median (interquartile range, IQR) age of 9.9 (7.8-11.7) years, and median (IQR) duration on GFD of 2.5 (2-5.5) years. Good GFD adherence, assessed by Biagi score, was reported in 93.1% of cases. GIP was evaluated during 134 visits, with GIP detected in 27 of 134 (20.1%) of the visits (16.3% of stool samples and 5.3% of urine samples). Positive GIP results were significantly more common in males compared to females (30.6% vs 14.1%, respectively, P < 0.05). Detection of positive GIP was not associated with dietary assessment of GFD adherence, celiac serology results, or reported symptoms. CONCLUSIONS: Stool and urine GIP can be detected in children with CeD, even when dietary assessment indicate good adherence to GFD. The role of GIP testing in clinical practice should be further explored.

Background: The increased intake of FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyol) rich foods has been suggested as a possible trigger of functional gastrointestinal disorders (FGIDs). Despite the high FODMAP content, the Mediterranean diet (MD) appears to have beneficial effects on health. Our aim was to evaluate whether the prevalence of FGIDs in different Mediterranean countries may be influenced by FODMAP consumption and adherence to the MD. Methods: A school-based, cross-sectional, multicenter study was performed in six countries in the Mediterranean area: Croatia, Greece, Israel, Italy, Macedonia, and Serbia. Subjects 4-18 years were examined in relation to their eating habits and the presence of FGIDs, using Rome IV criteria, 3-day food diaries and Mediterranean Diet Quality Index in Children and Adolescents (KIDMED) questionnaires. Results: We enrolled 1972 subjects between 4 and 9 years old (Group A), and 2450 subjects between 10 and 18 years old (Group B). The overall prevalence of FGIDs was 16% in Group A and 26% in Group B. FODMAP intake was significantly different among countries for both age groups. In both groups, no significant association was found between FGIDs and FODMAPs. Adherence to the MD in all countries was intermediate, except for Serbia, where it was low. In both groups, we found a statistically significant association between FGIDs and the KIDMED score (Group A: OR = 0.83, p < 0.001; Group B: OR = 0.93, p = 0.005). Moreover, a significant association was found between the KIDMED score and functional constipation (Group A: OR = 0.89, p = 0.008; Group B: OR = 0.93, p = 0.010) and postprandial distress syndrome (Group A: OR = 0.86, p = 0.027; Group B: OR = 0.88, p = 0.004). Conclusions: Our data suggest that the prevalence of FGIDs in the Mediterranean area is not related to FODMAP consumption, whereas adherence to the MD seems to have a protective effect.

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.

OBJECTIVE: We aimed to assess how the first phase of coronavirus disease 2019 (COVID-19) pandemic influenced symptoms in children with functional abdominal pain disorders (FAPDs) and to characterize their quality of life (QoL), anxiety and global health. METHODS: This was a multicenter, observational, international study conducted between April and July 2020 at six different referral centers. Children diagnosed with FAPDs between October 2019 and February 2020 were enrolled and prospectively interviewed at 4âmonths of follow-up during the first pandemic phase (Quarantine group). Patients were asked to complete PedsQL 4.0 Generic Core Scale and PROMIS Anxiety and Global Health questionnaires. A cohort of children diagnosed with FAPDs between October 2018 and February 2019 was used as a Control group. RESULTS: Three-hundred-fifty-six children were enrolled of whom 180 (mean age at diagnosis: 14â±â2.8âyears) in the Quarantine group and 176 (mean age at diagnosis: 13â±â2.8âyears) in the Control group. At 4âmonths of follow-up, we observed a significant reduction of children reporting >5 episodes of abdominal pain per month when compared to baseline, in both groups (Quarantine group: 63.9% vs 42.2%, Pâ<â0.001; Control group: 83.5% vs 50%, Pâ<â0.001). The Quarantine group had median QoL values of 84.8 with 16.6% of children showing high anxiety values and 55% having decreased global health score. CONCLUSIONS: We demonstrated symptoms' improvement at 4âmonths of follow-up in both cohorts. During the first months of the COVID-19 quarantine children with FAPDs showed satisfactory QoL and anxiety scores, suggesting positive effects of school closure and increased parental attention.

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.

BACKGROUND & AIMS: Little is known about the prevalence of functional gastrointestinal disorders (FGIDs) in children from the Mediterranean area of Europe. We aimed to assess the prevalence of FGIDs in children and adolescents in this region. METHODS: We collected data on 13,750 children (4-18 years old) enrolled in the Mediterranean-European Area Project, a school-based health study performed in Croatia, Greece, Israel, Italy, Jordan, Lebanon, Macedonia, Serbia, and Spain. Data were collected from March to June and in September of 2016. We analyzed data from 6602 students 4 to 10 years old (group A; mean age, 7.7 ± 1.9 y), and 7148 subjects 11 to 18 years old (group B; mean age, 13.8 ± 2.1 y). Children with FGIDs were identified based on answers to questionnaires on pediatric gastrointestinal symptoms, selected based on Rome III criteria. RESULTS: In group A, the prevalence of FGIDs was 20.7%. The most frequent disorders were functional constipation (11.7%), irritable bowel syndrome (IBS, 4%), aerophagia (3.5%), and abdominal migraine (3.1%). The prevalence of abdominal migraine was significantly higher in girls than in boys (P = .007). In group B, the overall prevalence of FGIDs was 26.6%. The most frequent disorders were functional constipation (13.1%), abdominal migraine (7.8%), aerophagia (6.3%), and IBS (5.6%). In group B, FGIDs had a higher prevalence among girls than boys (P < .001). In both groups, we found significant differences in the prevalence of specific disorders among specific countries. CONCLUSIONS: In an analysis of data on children 4 to 18 years old from the Mediterranean-European Area Project, we found FGIDs to be more frequent in girls. Functional constipation, aerophagia, abdominal migraine, and IBS are the most common disorders. However, the prevalence of FGIDs varies significantly among countries.
