The primary role of environment on inflammatory bowel disease (IBD) onset has been recently stressed. We aimed to investigate the effect of environmental factors in an IBD pediatric cohort.A total of 467 subjects (264 IBD and 203 controls) were enrolled. All patients underwent a questionnaire including 5 different groups of environmental risk factors: family history of IBD and autoimmune diseases, perinatal period, home amenities and domestic hygiene, childhood diseases and vaccinations, and diet.In a multivariate model, mother's degree (odds ratio [OR]: 5.5; 2.5-11.6), duration of breast feeding3rd month (OR: 4.3; 1.6-10.5), father's employment (OR: 3.7; 1.2-8.7), gluten introduction6th month (OR: 2.8; 1.5-5), number of siblings2 (OR: 2.8; 1.5-5.3), and family history of autoimmune diseases (OR: 2.7; 1.4-5.3) were significant risk factors for Crohn disease. Low adherence to Mediterranean diet (OR: 2.3; 1.2-4.5), gluten introduction6th month (OR: 2.8; 1.6-4.9), and number of siblings2 (OR: 2; 1.1-3.6) were significant risk factors for ulcerative colitis. Owning pets (OR: 0.3; 0.1-0.7) and bed sharing (OR: 0.2; 0.1-0.6) were protective factors for Crohn disease, whereas owning pets (OR: 0.4; 0.2-0.8) and family parasitosis (OR: 0.07; 0.01-0.4) were protective factors for ulcerative colitis.Our study confirms that environmental factors are closely linked to IBD onset and may partly explain IBD rise in developed countries.

Objectives: The aims of our study were to evaluate health-related quality of life (HRQoL) in children affected by inflammatory bowel disease (IBD) during the first wave of Coronavirus disease 2019 (COVID-19) pandemic and after 12 months. Methods: This was a single-center, prospective, observational study conducted between April 2020 and April 2021. Children from 10 to 18 years with a confirmed diagnosis of IBD were enrolled during the first COVID-19-related national quarantine. The following information was collected at the baseline and after 12 months: IBD subtype, location and phenotype, disease activity, current and previous therapies. Patients were asked to complete the PROMIS Anxiety and IMPACT III questionnaires. Results: One hundred and eighteen patients were enrolled, of whom 54 (46%) were affected by Crohn disease (CD) and 64 (54%) with ulcerative colitis (UC; median age: 15.5 years, range 10.3-18; M/F: 68/50). Median HRQoL was significantly decreased after 12 months compared with the beginning of COVID-19-related quarantine (T1: 76.7 vs T2: 72.8; P < 0.001). At 12 months, a higher number of children were reported to be in active disease when compared with the enrollment [T2: 22/108 (20.4%) vs T1: 12/118 (10%); P = 0.02]. Multivariate analysis showed a significant influence on HRQoL of quarantine period (P < 0.001), female sex (P = 0.016), biologic therapy (P = 0.011), and active disease (P < 0.001). Conclusions: A deterioration of HRQoL after 12 months from COVID-19-related quarantine was observed. Additionally, the higher number of children with active disease at 12 months compared with enrollment may suggest detrimental consequences of the reduced disease control, contributing to decreased HRQoL.

Background: The new concept of disease remission for pediatric inflammatory bowel diseases (IBD) implies the achievement of mucosal healing. Aims: We aimed to evaluate endoscopic and histologic healing in children with Ulcerative Colitis (UC) and Crohn's disease (CD) in clinical remission after 52 weeks of Azathioprine. Methods: From December 2012 to July 2015 we prospectively enrolled IBD children starting Azathioprine. Enrolled patients in clinical remission underwent colonoscopy after 52 weeks. Macroscopic assessment was described with Mayo score and the simplified endoscopic score for UC and CD, respectively. For microscopic assessment, an average histology score was used. Data on inflammatory markers and fecal calprotectin were also collected. Results: Fourty-seven patients were included in the analysis. Endoscopic healing was detected in 20/26 (76.9%) UC children and 10/21 (47.6%) CD patients. Median Mayo score and simplified endoscopic score were significantly decreased at week 52 (p < 0.001; p = 0.005). Median average histology score was not significantly different at week 52 in both diseases. Fecal calprotectin was directly correlated with simplified endoscopic score (T0: r = 0.4, p = 0.05; T52: r = 0.5, p = 0.01), but not with Mayo score. No correlation was found between endoscopic and histologic scores. Conclusions: IBD children under Azathioprine reach endoscopic healing, but not histological remission.

BackgroundVaccine-preventable diseases and opportunistic infections in pediatric inflammatory bowel disease (IBD) are increasingly recognized issues. The aims of this study were to evaluate vaccinations, immunization status, and consequent therapeutic management in children with IBD and to analyze the differences among patients diagnosed before (Group 1) and after June 2012 (Group 2).MethodsThis was a multicenter, retrospective cohort investigation. Between July 2016 and July 2017, 430 children with IBD were enrolled in 13 centers. Diagnosis, therapeutic history, vaccinations, and immunization status screening at diagnosis and at immunosuppressant (IM)/biologic initiation and reasons for incomplete immunization were retrieved.ResultsVaccination rates at diagnosis were unsatisfactory for measles, mumps, and rubella (89.3%), Haemophilus influenzae (81.9%), meningococcus C (23.5%), chickenpox (18.4%), pneumococcus (18.6%), papillomavirus (5.9%), and rotavirus (1.9%). Complete immunization was recorded in 38/430 (8.8%) children, but specific vaccines were recommended in 79/430 patients (18.6%), without differences between the 2 groups. At IM start, 22% of children were tested for Epstein-Barr virus (EBV) status, with 96.2% of EBV-naïve patients starting azathioprine, without differences between Groups 1 and 2. Screening for latent tuberculosis (TB) before start of biologics was performed in 175/190 (92.1%), with up to 9 different screening strategies and numerous inconsistencies.ConclusionsWe demonstrated a poor immunization status at diagnosis in children with IBD, which was not followed by proper vaccination catch-up. EBV status before IM initiation and latent TB before biologics were not adequately assessed. Thus, the overall impact of the current guidelines seems unsatisfactory.

OBJECTIVES Existing studies usually do not measure the free vitamin D in pediatric patients with inflammatory bowel disease (IBD) and not consider the effect of inflammation on vitamin D levels. The aim of our study was to evaluate the concentrations of vitamin D-binding protein (VDBP), total and free 25-hydroxyvitamin-D (25(OH)D), and to correlate these values with the disease activity markers. METHODS Newly diagnosed children with IBD and a group of healthy controls (HCs) were enrolled. VDBP and total and free 25(OH)D levels were measured by enzyme-linked immunosorbent assay and compared using the Student t test. In each patient with IBD, the activity scores of disease and the main inflammation markers were correlated to total and free 25(OH)D levels. C-reactive protein was also measured in the control group, and it was related to VDBP by a linear regression test for all the groups. RESULTS Fifty-one consecutive children were enrolled: IBD = 33, HC = 18. Levels of total 25(OH)D were higher in HC than in patients with IBD (P = 0.01). The free/total 25(OH)D ratio was, however, higher in patients with IBD compared to HC (P

Background Infant colic (IC) is a prevalent physiological event of infants, which can disrupt the child's home environment. We aimed to investigate the effectiveness of a mixture of Matricariae chamomilla L., Melissa officinalis L. and tyndallized Lactobacillus acidophilus (HA122) compared with Lactobacillus reuteri DSM 17938 and with simethicone for the treatment of IC. Methods A multicenter randomized comparative study was conducted in infants with colic, according to Rome III criteria, who were randomly assigned to receive M. chamomilla L., M. officinalis L. and tyndallized L. acidophilus (HA122) (Colimil® Plus®; Milte Italia Spa, Milan, Italy) (Group A), L. reuteri DSM 17938 (Group B) and simethicone (Group C). Treatment was given to subjects for 28 days. Key Results One-hundred and seventy-six patients completed the study. Mean daily crying time at day 28 was significantly lower in group A (−44, 95% CI: −58 to −30, P

Infant colic is a prevalent physiological event of healthy children under 3 months of age, which can disrupt the child's home environment. Despite its benign natural history, sometimes it requires a therapeutic approach. There is limited evidence supporting the use of complementary and alternative treatments. The aim of this study was to investigate the effectiveness of a mixture of standardized extract of matricariae Chamomilla L., Melissa Officinalis L. and tyndallized Lactobacillus Acidophilus (H122) compared with Lactobacillus Reuteri (DSM 17938) and with simethicone for the treatment of infantile colic.
