Abstract
Due to its unclear etiology, there is no specific medicine to cure the recurrent and incurable inflammatory bowel disease (IBD). Unhealthy dietary habits unconsciously contributed to the progression of IBD, for example a High-Salt-Diet (HSD) is the most neglected and frequently adopted habit. However, the molecular mechanism of how HSD aggravates the progression of IBD has yet to remain uncovered. Herein, we focus on the hypothesis that necroptosis pathway may be involved in the process of IBD exacerbated by HSD. To this end, different gene expression (DEGs) profiles of human epithelia under hypertonic culture conditions were applied to screen candidate pathways. What's more, gene expression manipulation, immune microenvironment detection, RIPK3/MLKL gene knockout (KO), and wild-type (WT) mice were carried out to research the promotion of IBD progression under treatments of high salt intake. Based on our present results, gene expression profiles in human normal colon epithelia cell NCM460 were significantly changed under salt- or sucrose-induced hypertonic culture conditions. RIPK3 was significantly up-regulated under both conditions. Furthermore, mice colon epithelia cell CT26 growth was inhibited in a time- and dose-dependent manner by extra NaCl incubation. Autophagy, and Necroptosis pathways were activated and enhanced by LPS pretreatment. HSD significantly exacerbated DSS-induced IBD symptoms in vivo in a dose-dependent manner. Moreover, RIPK3-/- and MLKL-/- mice presented severe IBD symptoms in vivo. Overall, the results demonstrated that HSD aggravated the IBD progression via necroptosis activation, providing novel strategies and promising targets for the clinical treatment of IBD.

Abstract
BACKGROUND Pediatric inflammatory bowel disease (IBD) is a chronic inflammatory intestinal disease that affects both children and adolescents. Symptoms can significantly affect a child's growth, development, and quality of life, making early diagnosis and effective management crucial. This study focuses on treatment-naïve pediatric IBD patients and their immediate families to identify the role of the microbiome in disease onset. METHODS Nine families with pediatric IBD were recruited, comprising seven drug-naïve Crohn's disease (CD) patients and two drug-naïve ulcerative colitis (UC) patients, as well as twenty-four healthy siblings/parents. Fecal samples were collected for 16S ribosomal RNA gene sequencing and bioinformatics analysis. RESULTS We identified patterns of dysbiosis and hallmark microbial taxa among patients who shared ethnic, habitual, and dietary traits with themselves and their families. In addition, we examined the impact of the disease on specific microbial taxa and how these could serve as potential biomarkers for early detection. CONCLUSIONS Our results suggest a potential role of maternal factors in the establishment and modulation of the early life microbiome, consistent with the current literature, which may have implications for understanding the etiology and progression of IBD.

Abstract
OBJECTIVES Recent insights supporting the safety of live-attenuated vaccines and novel studies on the immunogenicity of vaccinations in the era of biological disease-modifying antirheumatic drugs in paediatric patients with autoimmune/inflammatory rheumatic diseases (pedAIIRD) necessitated updating the EULAR recommendations. METHODS Recommendations were developed using the EULAR standard operating procedures. Two international expert committees were formed to update the vaccination recommendations for both paediatric and adult patients with AIIRD. After a systematic literature review, separate recommendations were formulated for paediatric and adult patients. For pedAIIRD, six overarching principles and seven recommendations were formulated and provided with the level of evidence, strength of recommendation and Task Force level of agreement. RESULTS In general, the National Immunisation Programmes (NIP) should be followed and assessed yearly by the treating specialist. If possible, vaccinations should be administered prior to immunosuppressive drugs, but necessary treatment should never be postponed. Non-live vaccines can be safely given to immunosuppressed pedAIIRD patients. Mainly, seroprotection is preserved in patients receiving vaccinations on immunosuppression, except for high-dose glucocorticoids and B-cell depleting therapies. Live-attenuated vaccines should be avoided in immunosuppressed patients. However, it is safe to administer the measles-mumps-rubella booster and varicella zoster virus vaccine to immunosuppressed patients under specific conditions. In addition to the NIP, the non-live seasonal influenza vaccination should be strongly considered for immunosuppressed pedAIIRD patients. CONCLUSIONS These recommendations are intended for paediatricians, paediatric rheumatologists, national immunisation agencies, general practitioners, patients and national rheumatology societies to attain safe and effective vaccination and optimal infection prevention in immunocompromised pedAIIRD patients.

Abstract
Objective and aim Infantile-onset inflammatory bowel disease (IO-IBD), defined as IBD diagnosed at age 2 years or younger, tends to be more severe and refractory to conventional treatment than IBD diagnosed at a later age. However, data about IO-IBD and its long-term follow up are limited. We thus aimed to evaluate the presentation and long-term outcomes of patients with IO-IBD in a retrospective multicenter study. Methods Medical records of patients diagnosed with IO-IBD in eight medical centers during 2000-2017 with at least 1-year follow up were reviewed. Demographics and disease characteristics at diagnosis including age of onset, disease phenotype and location, surgeries, medical therapy, and comorbid conditions were recorded. Results Twenty-three patients with IO-IBD (16 males, 70%) were identified and followed for a median (range) of 51.2 (26.0-110.3) months. The mean ages at presentation and at the last follow up were 14 ± 9.8 and 101 ± 77 months, respectively. Six (26%) patients needed ileostomy already at the time of diagnosis and 20 (87%) were treated with corticosteroids. During long-term follow up, remission was achieved in 16 (73%) patients; of whom, 3 (14%) were without medications and 7 (32%) were in remission with the use of 5-aminosalicylic acid only. One patient needed hemicolectomy and one developed a severe EBV related infection. Conclusion The majority of patients with IO-IBD achieved long-term remission, despite a severe disease presentation at diagnosis. Surgery rate however is high, mainly during the first months from diagnosis.

Abstract
OBJECTIVE The coronavirus disease 2019 (COVID-19) pandemic has impacted everyone, but there are few data regarding how the pandemic has influenced the lives of children with gastrointestinal (GI) conditions. This cross-sectional study assessed pandemic-related social disruption (PRSD) in children with inflammatory bowel disease (IBD), celiac disease (CD), and irritable bowel syndrome (IBS), and the potential buffering effect of the parent-child relationship. METHODS A survey completed between September and December 2020 asked 146 children (ages 8-17) diagnosed with IBD (n = 44), CD (n = 81), or IBS (n = 51) and 185 parents how the pandemic has contributed to social disruption (i.e., financial stability, COVID-19 exposure, school changes, GI needs, and isolation) and their social-emotional well-being. Structural equation modeling was used to examine the role of social disruption on well-being, and the moderating effect of the parent-child relationship. RESULTS Increased social disruption predicted worse parent, β = 0.24, p = .02, and child well-being, β = 0.38, p < .01. The parent-child relationship moderated the relationship between parent and child well-being, β = 0.21, p = .03. Strong parent-child relationships predicted a positive association between parent and child well-being, β = 0.23, p = .003, whereas medium, β = 0.09, p = .14, and poor, β = -0.06, p = .52, relationships did not. CONCLUSIONS PRSD negatively impacted the well-being of children with GI conditions, and the parent-child relationship moderated this relationship. These findings are relevant to pediatric psychologists treating the physical and mental health needs of children with GI conditions and their parents.

Abstract
Background Inflammatory bowel disease (IBD) is a chronic gastrointestinal tract inflammatory state, which is affecting millions of individuals in the world. It can affect alimentary canals such as colon, rectum, ileum and other parts. In IBD, platelet parameters underwent several changes. Therefore, the aim of this review was determining the estimated pooled mean platelet volume and mean difference in inflammatory bowel disease to elucidate its potential diagnostic value. Methods Articles were extensively searched in bibliographic databases using Medical Subject Heading and entry phrases or terms. In addition, articles were directly searched in Google Scholar to account for the studies omission in searching bibliographic databases. Observational (cohort, cross-sectional and case-control) studies, published in English language and conducted on IBD were included. For studies meeting the eligibility criteria, the first author’s name, publication year, population, study design, study area, sample size, mean platelet volume and standard deviation were extracted and entered in to Microsoft-excel. The analysis was done by Stata version 11. In order to estimate the pooled mean platelet volume and mean difference, random effect model was done. The heterogeneity was quantified using Higgin’s I2 statistics. Publication bias was determined using Egger’s test statistics and funnel plot. Sub-group analysis based on population carried to reduce heterogeneity. Results A total of 17 relevant articles with 2957 participants (1823 IBD cases and 1134 healthy controls) were included to this study. The pooled estimated MPV was 9.29fl; 95% CI: 9.01–9.57 and 9.50fl; 95% CI: 8.81–10.20 in IBD and control groups, respectively. The standardized pooled estimate of mean difference in mean platelet volume was -0.83fl; 95% CI: -1.15, -0.51; I2: 93.1%; P-value < 0.001. In subgroup analysis based on population, the highest estimated mean difference in MPV was observed among patients of CD; -2.30; 95% CI: -3.46, -1.14; I2: 97.8%; P-value < 0.001. Conclusion According to the current systematic review and meta-analysis, mean platelet volume was lower in IBD compared to control. The decreased mean platelet volume could be attributed to platelet consumption or sequestration associated with the progression of IBD. As a result, in IBD, mean platelet volume can provide diagnostic and prognostic information.

Abstract
A 20-year-old woman with Crohn's disease receiving infliximab therapy presented to the emergency department with lower extremity swelling secondary to compression of the common iliac vein. On magnetic resonance imaging, an enlarging pelvic mass was identified. The pathology of the mass was consistent with myelolipoma. We believe this is the first case of myelolipoma in a patient on immunosuppression with infliximab.

Abstract
BACKGROUND Long non-coding antisense RNAs in the INK4 locus (lnc-ANRIL) have been reported to be involved in inflammation and immunity. However, few studies have reported its clinical application in pediatric inflammatory bowel disease (IBD). Therefore, we conducted this study to investigate the correlation between lnc-ANRIL expression and disease risk, inflammation, and activity in pediatric IBD patients. METHODS Pediatric patients with Crohn's disease (CD; n = 40), ulcerative colitis (UC; n = 40), and controls (n = 20) were recruited. For all pediatric IBD patients, lnc-ANRIL expression in peripheral blood mononuclear cells and serum inflammatory cytokine levels were measured by RT-qPCR and ELISA, respectively. For the controls, lnc-ANRIL expression was also measured. RESULTS Lnc-ANRIL levels were lower in CD (P = 0.002) and UC (P = 0.001) patients compared with the controls; negatively correlated with C-reactive protein levels (P<0.01), erythrocyte sedimentation rate (P<0.01), disease activity (P<0.05), and severity (P<0.05) in CD and UC patients; and inversely associated with tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-17, and IL-23 levels in both CD and UC patients (all P<0.01). Further subgroup analyses revealed that the association between lnc-ANRIL and inflammatory cytokines and disease activity was more remarkable in pediatric patients with moderate or severe IBD. CONCLUSION Lnc-ANRIL may serve as a potential marker for evaluating disease risk and monitoring disease activity in pediatric IBD patients.

Abstract
The use of biological drugs has improved outcomes in pediatric inflammatory bowel disease (IBD). Prediction of the response to biological drugs would be extremely useful in IBD, and even more so in children, who are still growing physically and psychologically. Specific clinical, biochemical, and genetic parameters are considered predictive of response to biological drugs, although few studies have been carried out in children with IBD. In this review, we present current evidence on biological treatments used in pediatric IBD and the available biomarkers of response. We examine demographics, clinical characteristics, biomarkers (genetic, genomic, and cellular), and microbiota.

Abstract
Objective To describe risk factors for IBD development in a cohort of children with JIA. Methods JIA patients who developed IBD were identified from the international Pharmachild register. Characteristics were compared between IBD and non-IBD patients and predictors of IBD were determined using multivariable logistic regression analysis. Incidence rates of IBD events on different DMARDs were calculated, and differences between therapies were expressed as relative risks (RR). Results Out of 8942 patients, 48 (0.54% ) developed IBD. These were more often male (47.9% vs 32.0%) and HLA-B27 positive (38.2% vs 21.0%) and older at JIA onset (median 8.94 vs 5.33 years) than patients without IBD development. They also had more often a family history of autoimmune disease (42.6% vs 24.4%) and enthesitis-related arthritis (39.6% vs 10.8%). The strongest predictors of IBD on multivariable analysis were enthesitis-related arthritis [odds ratio (OR): 3.68, 95% CI: 1.41, 9.40] and a family history of autoimmune disease (OR: 2.27, 95% CI: 1.12, 4.54). Compared with methotrexate monotherapy, the incidence of IBD on etanercept monotherapy (RR: 7.69, 95% CI: 1.99, 29.74), etanercept with methotrexate (RR: 5.70, 95% CI: 1.42, 22.77) and infliximab (RR: 7.61, 95% CI: 1.27, 45.57) therapy was significantly higher. Incidence on adalimumab was not significantly different (RR: 1.45, 95% CI: 0.15, 13.89). Conclusion IBD in JIA was associated with enthesitis-related arthritis and a family history of autoimmune disease. An increased IBD incidence was observed for etanercept therapy regardless of concomitant methotrexate use.

Abstract
Introduction: Current therapies in pediatric Inflammatory Bowel Diseases (IBD) target the immune system and often fail to sustain long-term remission. There is a high need for development of alternative treatment strategies such as antibiotics in pediatric IBD.Areas covered: This study systematically assessed efficacy and safety of antibiotics in pediatric IBD. CENTRAL, EMBASE, and Medline were searched for Randomized Controlled Trials (RCTs). Quality assessment was conducted with the Cochrane risk-of-bias tool.Expert opinion: Two RCTs (n = 101, 4.4-18 years, 43% male) were included. Both studies had overall low risk of bias. In mild-to-moderate Crohn's disease, azithromycin+metronidazole (AZ+MET) (n = 35) compared to metronidazole (MET) alone (n = 38) did not induce a significantly different response (PCDAI drop ≥12.5 or remission) (p = 0.07). For induction of remission (PCDAI≤10), AZ+MET was more effective than MET (p = 0.025). In Acute Severe Colitis, mean 5-day-PUCAI was significantly lower in the antibiotic (vancomycin, amoxicillin, metronidazole, doxycycline)+intravenous-corticosteroids group (AB+IVCS) (n = 16) compared to IVCS alone (n=12) (p = 0.037), whereas remission (PUCAI<10) did not differ (p = 0.61). No significant drug-related adverse events were reported. Results of this systematic review of antibiotic use highlight the lack of evidence in pediatric IBD. More evidence is needed before widespread implementation in daily practice.

Abstract
Inflammatory bowel disease incidence has been constantly rising for the past few decades. Current therapies attempt to mitigate its symptoms since no cure is established. The most commonly prescribed drug for these patients is 5-aminosalicylic acid (5-ASA). Due to the low rate and seriousness of side effects compared to other therapies, 5-ASA is still largely prescribed in many stages of inflammatory bowel disease, including scenarios where evidence suggests low effectiveness. Although commercialized formulations have come a long way in improving pharmacokinetics, it is still necessary to design and develop novel delivery systems capable of increasing effectiveness at different stages of the disease. In particular, micro- and nano-sized particles might be the key to its success in Crohn's disease and in more serious disease stages. This review provides an overview on the clinical significance of 5-ASA formulations, its limitations, challenges, and the most recent micro- and nanoparticle delivery systems being designed for its controlled release. Emergent alternatives for 5-ASA are also discussed, as well as the future prospects for its application in inflammatory bowel disease therapies.

Abstract
Background: Infusion reactions (IRs) are the most common adverse events (AEs) of infliximab (IFX) treatment in patients with inflammatory bowel disease (IBD). Prophylactic premedication (PM) with corticosteroids or antihistamines prior to IFX infusions has been used in clinical practice, but its efficacy is not known. The aim of this study was to assess the influence of steroid PM on IR incidence in pediatric patients with IBD receiving IFX. Methods: We performed a case–control study that included pediatric patients with IBD receiving IFX. Patients were divided into four subgroups according to the agent and PM they received: Remicade (original drug) + PM, and two biosimilars—Reshma +/− PM, and Flixabi—PM. At our site, until 2018, PM with steroids was used as a part of standard IFX infusion (PM+); however, since then, this method has no longer been administered (PM−). IRs were divided into mild/severe reactions. Differences between subgroups were assessed with the appropriate chi-square test. Multivariate logistic regression was used to assess associations between PM and IR incidence, correcting for co-medication usage. Results: There were 105 children (55 PM+, 44 male, mean age 15 years) included in the study who received 1276 infusions. There was no difference between the PM+ and PM− subgroups, either in incidence of IR (18.2% vs. 16.0% of patients, p > 0.05) or in percentage of infusions followed by IR (2.02% vs. 1.02% of infusions, p > 0.5). The OR of developing IR when using PM was 0.34, and the difference in IRs ratio in PM+ and PM− patients was not statistically significant (95% CI, 0.034–1.9). There were 11/18 (61.1%) severe IRs (anaphylactic shock) reported in all patients (both PM+ and PM−). Conclusion: At our site, the incidence of IR was low, and PM did not decrease the incidence of IR in pediatric patients with IBD receiving IFX. These results indicate that PM with steroids should not be a standard part of IFX infusion to prevent IR.

Abstract
The prevalence of inflammatory bowel disease (IBD) has increased over the past 20 years. Pulmonary involvement in paediatric IBD is rare but may be missed since the spectrum of symptoms is broad and mimics other diseases. The most important differential diagnoses of pulmonary manifestations of IBD are infections and therapy-related side-effects. There is no gold standard to diagnose respiratory manifestations in children with IBD. Diagnostic tests should be chosen according to history and clinical presentation. Treatment of respiratory manifestations of IBD includes inhaled or oral corticosteroids and initiation or step-up of immunomodulatory IBD therapies. Pulmonary involvement in paediatric IBD is rare but may be underdiagnosed. The spectrum of symptoms is broad and mimics other diseases. The differentiation between IBD-related and drug-induced pulmonary manifestation can be challenging.https://bit.ly/3uZBvpA

Abstract
OBJECTIVES Retrospective, observational, single-center, cohort study investigating the safety profile of biological therapy in children with inflammatory bowel disease (IBD). METHODS Retrospective, observational, cohort study of pediatric patients with IBD, receiving infliximab, adalimumab, vedolizumab, or ustekinumab for at least 2 months. Data related to the immediate and delayed adverse events (AEs) were collected, focusing on the reaction type and severity, the time of onset, the outcome and the temporary or definitive therapy discontinuation secondary to the AE. Number of suspected and confirmed coronavirus disease-209 (COVID-19) cases and their outcomes, as well as flu vaccination coverage were collected. RESULTS One hundred eighty-five children were included (101 [55%] CD, 82 [44%] UC, and 2 [1%] IBDU): 149 received infliximab (IFX) (81%), 88 (48%) adalimumab (ADA), 18 (21%) vedolizumab, and 4 (2%) ustekinumab. The overall AE rates were 49%, 67% of whom likely medication-related. Eleven (6%) patients experienced more than 1 AE, 18 patients (10%) presented an immediate reaction, and 82 (45%) a delayed AE. Among the 90 patients experiencing at least 1 AE, 97% had mild-to-moderate AEs. Only 4 SAEs were reported (4%). Treatment discontinuation because of AE occurred in 25 patients (14%). Four COVID-19 cases were reported, all with a mild course. CONCLUSIONS Our findings confirm a good safety profile of biologics. Infusion reactions to IFX administration remain one of the main issues, significantly linked to its immunogenicity and consequently with an impact on its efficacy and durability.

Abstract
OBJECTIVES Blood to measure infliximab (IFX) levels is typically obtained with venipuncture. Dried blood sampling (DBS), using capillary blood obtained from a finger prick, would be an alternative to measure IFX blood levels while being more patient friendly. The aim of this study is to compare IFX blood level measured by venipuncture versus DBS in patients with paediatric inflammatory bowel disease (PIBD) to assure accuracy. METHODS A prospective clinical pilot study was performed in patients with PIBD. Before IFX infusion, blood was collected simultaneously through venipuncture and DBS from a finger prick, using Mitratips (Neoteryx). All IFX concentrations were measured by an enzyme-linked immunosorbent assay. The Bland-Altman analysis was used to measure limits of agreement. The interrater reliability was measured with the interclass correlation coefficient and Cohen kappa. To calculate Cohen kappa, IFX levels were categorized into 3 groups; low <5 μg/mL, adequate 5 to 10 μg/mL, and high >10 μg/mL. RESULTS Twenty patients were included. Median age was 12.1 year (interquartile range 8-16 year). The mean difference between the 2 methods was -0.14 as calculated with Bland-Altman plot. The limits of agreement were between -1.39 and 1.12. The interclass correlation coefficient was with 0.998 excellent. The Cohen kappa between 3 IFX level categories was strong K = 0.911 (P = 0.0001). There was a strong correlation between venous IFX serum levels and DBS (r = 0.991, P = 0.0001) in the included patients. CONCLUSIONS This is the first study in patients with PIBD to show that bloodspot technology is a patient friendly alternative method to measure IFX blood levels in PIBD.

Abstract
OBJECTIVES Inflammatory bowel disease (IBD) is more complex in children and they will have to live with the disease for much longer. For this reason, it is necessary to optimize treatment. The polymorphisms associated with the response to anti-tumor necrosis factor (TNF) drugs in adults with IBD have not been analyzed in children. The aim of the study was to identify genetic variants associated with the long-term response to anti-TNF drugs in children with IBD. METHODS An observational, longitudinal, ambispective cohort's study was conducted. We recruited 209 anti-TNF-treated children diagnosed with IBD and genotyped 21 polymorphisms previously studied in adults with Crohn disease (CD) using real-time PCR. The association between single-nucleotide polymorphisms (SNPs) and time-to-failure was analyzed using the log-rank test. RESULTS After multivariate analysis, 3 SNPs in IL10, IL17A and IL6 were significantly associated with response to anti-TNF treatment among patients diagnosed with CD (rs1800872-HR, 4.749 (95% confidence interval [CI] 1.156-19.517), P value < 0.05; rs2275913-HR, 0.320 [95% CI 0.111-0.920], P value < 0.05; and rs10499563-HR, 0.210 [95% CI 0.047-0.947], P value 0.05, respectively). None of these SNPs were associated with response to infliximab in adults diagnosed with CD. Among patients diagnosed with ulcerative colitis (UC), 1 SNP in LY96 was significantly associated with response to anti-TNF treatment (rs-11465996-HR, 10.220 [95% CI 1.849-56.504] P value < 0.05). CONCLUSIONS Genotyping of these DNA variants before starting treatment may help to identify children who are long-term responders to anti-TNF drugs, and thus tailor treatment of pediatric IBD.

Abstract
WHAT IS KNOWN AND OBJECTIVE Based on extrapolation, biosimilar infliximab (IFX) was approved to treat inflammatory bowel disease (IBD). The first studies in adults have shown similar efficacy and safety in comparison with reference drug. The aim of this review was to collect and evaluate all the literature data regarding the use of biosimilar IFX in paediatric IBD. METHODS This article reviewed efficacy, immunogenicity and safety profile of biosimilar IFX in IBD paediatric patients through a comprehensive search of the published literature. RESULTS AND DISCUSSION Eight papers were extracted and critically reviewed. Four paediatric studies (prospective, n = 3; retrospective, n = 1) assessed the induction efficacy of the biosimilar IFX. Clinical response and remission rates reported were 86%-90% and 67%-68%, respectively. No significant difference in clinical response and remission rates between the reference and biosimilar IFX groups was found at follow-up (range: 3-13 months). Similar findings were shown in the prospective studies (n = 4) conducted on patients elected to switch from reference IFX to its biosimilar. The most frequently reported adverse events (AEs) of biosimilar IFX were mild upper respiratory tract infections. Taking into account of all AEs coming from published data, biosimilar IFX seems to be as safe as its originator. Immunogenicity has not been significantly impacted by the switch from the reference drug. WHAT IS NEW AND CONCLUSION To date, treatment with (or switch to) biosimilar IFX in paediatric patients with IBD have been successful, without affecting efficacy, immunogenicity or safety. However, further studies are warranted, including clinical trials and pharmacovigilance studies.

Abstract
AIMS Identifying DNA variants associated with trough serum anti-tumour necrosis factor (TNF) levels could predict response to treatment in inflammatory bowel disease (IBD). To date, no specific studies have been performed in children. The aim of this study was to identify genetic variants associated with trough serum anti-TNF levels and whether these variants are differential markers for infliximab and adalimumab. METHODS We included 154 children (age < 18 years) from 17 hospitals who had been diagnosed with IBD and actively treated with infliximab or adalimumab. Twenty-one polymorphisms were genotyped using real-time PCR. Trough serum anti-TNF levels were measured using enzyme-linked immunosorbent assay (ELISA). The association between DNA polymorphisms and the therapeutic range or the absolute values of anti-TNF drugs was analysed by Fisher exact test, student's t-test and logistic regression. RESULTS The variants rs5030728 (TLR4) and rs11465996 (LY96) were associated with subtherapeutic infliximab levels. rs1816702 (TLR2) was associated with supratherapeutic levels and rs3397 (TNFRSF1B) with subtherapeutic levels of adalimumab (P < .05). In addition, rs1816702 (TLR2) and rs2569190 (CD14) were associated with absolute values of trough serum adalimumab, and rs2569190 (CD14) was associated with absolute values of trough serum adalimumab and infliximab (P < .05). CONCLUSION Genotyping of these DNA variants before starting treatment may help to select the best anti-TNF drug in paediatric patients. The SNP rs1816702 is the most promising marker for tailoring the anti-TNF regimen in children with IBD. For the first time, DNA variants are associated with trough serum anti-TNF levels.

Abstract
BACKGROUND/AIMS Crohn's Disease (CD) is a chronic inflammatory condition characterized by various abnormalities that lead to overly aggressive T-cell responses. Our in vitro experiments aimed to investigate the potential use of Dental Follicle Mesenchymal Stem Cells (DF-MSCs) to suppress the exaggerated immune response in inflamed and non-inflamed tissue of Crohn's Disease (CD). MATERIAL AND METHODS Dental follicle tissues were obtained from extracted third molar teeth of 3 healthy volunteers who have no abscess or inflammatory diseases. Eleven patients included the experiment who had been diagnosed with CD and not received steroid maintenance therapy for more than 1 month. Mononuclear Cells (MNCs) were isolated from inflamed and non-inflamed tissue of CD. Isolated cells were stimulated with anti-CD3/anti-CD28 monoclonal antibodies in the presence and absence of DF-MSCs and analyzed for lymphocytes proliferation capacity and viability, T lymphocyte subsets, CD4+IL22BP and CD4+CD25+Foxp3+ regulatory T cell (Tregs) frequencies and cytokine levels. RESULTS A significant downregulation of lymphocyte proliferation and CD4+IL22BP T cell ratio were found in inflamed cultures with DF-MSCs (p<0,005). Also, the frequency of Tregs increased with DF-MSCs (p<0,05). Pro-inflammatory cytokine levels (TNF-α and IL-6) were decreased (p<0,05) and IL-10 levels were increased (p<0,05) in the supernatant of inflamed cultures. CONCLUSION DF-MSCs reduced the inflammatory immune response, induced Tregs and downregulated CD4+IL22BP T cell ratio in inflamed samples of CD patients, which may be exploited for significant therapeutic use.

Abstract
BACKGROUND Biological therapies have modified the disease course of pediatric inflammatory bowel disease (IBD) and are routinely used in clinical practice. Our observational study aims to evaluate effectiveness and safety of biologics in IBD. METHOD Clinical benefit and safety data of 93 children with IBD, receiving biologics (Infliximab - IFX, Adalimumab - ADA, Golimumab - GOL) from January 2013 to December 2017, were extracted from the cohort of the Sicilian Network of IBD. RESULTS Among 87 children aged 7-17 years (63 Crohn's disease [CD], 24 Ulcerative colitis [UC]), 101 out of 108 biologic treatments were considered. Evaluation of 74 biologic treatments in CD patients at 26, 52, 104 weeks showed clinical benefit rates of 84.2%, 93.3%, 66.7% with IFX (n= 38) and 88.9%, 84.4%, 65.2% with ADA (n= 36). Biologic treatments (n=27) evaluated in the UC group at 26, 52, 104 weeks, led to clinical benefit rates of 85.7%, 83.3%, 50% in IFX subgroup (n=21) and 40%, 50%, 33% in the ADA subgroup (n=5), respectively. One patient treated with GOL showed 100% clinical benefit at 26 and 52 weeks. Overall adverse events (AEs) rate was 9.25%. Six younger children, <6 years, receiving 8 treatments (4 ADA, 4 IFX) presented a clinical remission rate of 75% at 12 weeks and 25% at 52 weeks. AEs rate was 25% in this group. CONCLUSION Our data show that biologic therapy in children, even at a younger age, is effective in allowing long-term remission with a good safety profile.

Abstract
The aim of the study was to determine the impact of biological treatment with tumor necrosis factor α antibodies (anti-TNF-α) on the intestinal microbiome of children with severe Crohn's disease (CD) and to evaluate the differences in the intestinal microbiome between patients treated with biological therapy and healthy children. Microbiota composition was analyzed by 16S next-generation sequencing (NGS) and microbial profiles were compared between studied groups. Fifty-four samples (from 18 patients before and after anti-TNF-α induction therapy and 18 healthy children) were used in the sequencing analysis. Shannon's diversity index (p = 0.003, adj. p = 0.010) and observed operational taxonomic units (OTUs) (p = 0.007, adj. p = 0.015) were different between controls and patients with prior therapy for CD. Statistically significant dissimilarities between beta diversity metrics, indicating distinct community composition across groups, were observed in patients with CD before and after therapy. We did not observe any differences between controls and patients with CD after therapy. Core microbiome analysis at species level showed that 32 species were present only in patients with CD but not in controls. The results show that biological treatment is associated with changes in the intestinal microbiome of patients with CD: these changes result in an intestinal microbiome pattern similar to that seen in healthy children. Long-term observation is necessary to determine whether treatment can lead to full restoration of a healthy-like microbiome.

Abstract
BACKGROUND & AIMS Aberrations in body composition are expected in children suffering from chronic inflammatory conditions. The objective is to examine whether children with inflammatory bowel disease (IBD: Crohn's disease and ulcerative colitis), coeliac disease, asthma and juvenile idiopathic arthritis (JIA) have an altered body composition as compared to healthy children. METHODS A systematic review, registered in Prospero (registration number: CRD42018107645), was conducted according to PRISMA guidelines. We conducted a search of three databases, Pubmed, Cochrane and Scopus. An assessment of the quality of the study was performed. RESULTS Data from 50 studies, 32 with IBD, 8 with coeliac disease, 2 with asthma and 8 with JIA, involving 2399 children were selected for review after applying the eligibility criteria. In all but 4 studies, children with Crohn's disease exhibited decreased amounts of fat mass and fat free mass. Reductions in fat mass were also evident in studies in children with coeliac disease. It is uncertain whether body composition is altered in children with asthma or JIA. CONCLUSIONS Children with Crohn's disease manifest with lowered adiposity and lean mass and therefore are likely to be at risk for suffering malnutrition-related clinical complications. Apart from Crohn's disease, data examining body composition in children with chronic inflammatory conditions are scarce and there is a paucity of reports examining the relationship between inflammation and body composition. Interpretation of the current study results is hampered by the low quality of the studies and due to the fact that the analyses have been habitually secondary outcomes.

Abstract
OBJECTIVES Therapeutic drug monitoring has been proposed as a useful tool in the management of infliximab (IFX) treated patients with inflammatory bowel disease. The aim of this retrospective study was to determine whether IFX trough levels after induction therapy are predictive for outcome at week 52. METHODS All pediatric patients with inflammatory bowel disease receiving maintenance IFX at our centre, with IFX trough level available at their first maintenance infusion and a follow-up of at least 52 weeks were included. IFX induction regimens could be intensified at the discretion of the treating physician. All children received proactive drug monitoring during maintenance with dose adaptation aiming to target a therapeutic window of 3 to 7 μg/mL. RESULTS We included 35 children (23 with Crohn disease and 12 with ulcerative colitis). Median IFX trough levels just before the first maintenance infusion were significantly higher in children achieving clinical (4.6 μg/mL [2.7-11.8] vs 1.5 μg/mL [0.9-3.0]), biological (4.6 μg/mL [2.5-10.3] vs 2.6 μg/mL [0.3-3.2]) and combined clinical/biological remission (6.0 μg/mL [3.2-12.0] vs 2.6 μg/mL [1.1-3.2]) at week 52 compared to children not meeting these criteria (all P ≤ 0.002). Binary logistic regression identified these trough levels as the only predictor for the same outcomes with an odds ratio (95% confidence interval) of 2.083 (1.085-3.998), 2.203 (1.101-4.408), and 2.264 (1.096-4.680), respectively (all P < 0.05). CONCLUSIONS Adequate IFX exposure during induction therapy is associated with better clinical and/or biological remission at week 52. Postinduction IFX trough levels were the only predictor for clinical and/or biological remission at week 52.

Abstract
Inflammatory bowel disease (IBD) presents with disabling symptoms and may lead to insufficient growth and late pubertal development in cases of disease onset during childhood or adolescence. During the last decade, the role of anti-tumor necrosis factor (TNF) in the treatment of paediatric-onset IBD has gained more ground. The number of biologicals presently available for children and adolescents with IBD has increased, biosimilars have become available, and practices in adult gastroenterology with regards to anti-TNF have changed. The aim of this study is to review the current evidence on the indications, judicious use, effectiveness and safety of anti-TNF agents in paediatric IBD. A PubMed literature search was performed and included articles published after 2000 using the following terms: child or paediatric, Crohn, ulcerative colitis, inflammatory bowel disease, anti-TNF, TNF alpha inhibitor, infliximab, adalimumab, golimumab and biological. Anti-TNF agents, specifically infliximab and adalimumab, have proven to be effective in moderate and severe paediatric IBD. Therapeutic drug monitoring increases therapy effectiveness and safety. Clinical predictors for anti-TNF response are currently of limited value because of the variation in outcome definitions and follow-ups. Future research should comprise large cohorts and clinical trials comparing groups according to their risk profile in order to provide personalized therapeutic strategies.

Abstract
BACKGROUND The role of therapeutic drug monitoring for infliximab [IFX] therapy in children with inflammatory bowel disease [IBD] is poorly investigated. We determined if IFX exposure correlates with long-term remission in children. METHODS In this retrospective study, all children with Crohn's disease [CD] and ulcerative colitis [UC], receiving maintenance IFX at our centre, were included. Serum trough levels and cumulative drug exposure were correlated with clinical, biological, and endoscopic remission. All children received proactive drug monitoring and dose adaptation aiming to target a therapeutic window of 3-7 µg/mL. All data are presented as median [interquartile range]. RESULTS A total of 686 serum levels during IFX maintenance in 52 paediatric patients [33 CD and 19 UC] were included (median 9 [4-18] per patient). With a median of 17 [8-36] months under IFX therapy, 39/52 [75%] patients were in clinical remission and 29/40 [73%] patients were in endoscopic remission. Median IFX trough levels were significantly higher when children achieved clinical remission (5.4 [3.8-8.0] µg/mL versus 4.2 [2.6-6.7] µg/mL), biological remission (5.2 [3.7-7.7] µg/mL versus 4.2 [2.6-6.5] µg/mL), combined clinical and biological remission (5.7 [4.0-8.2] µg/mL versus 4.4 [2.7-6.8] µg/mL) and endoscopic remission (6.5 [4.2-9.5] µg/mL versus 3.2 [2.3-5.6] µg/mL) compared with not meeting these criteria [all p ≤ 0.001]. CONCLUSIONS In this large paediatric cohort, children with clinical and/or endoscopic remission had significantly higher IFX exposure during maintenance therapy. We showed excellent outcome data using serial and systematic measurements of drug levels. This could provide a rationale for the use of proactive drug monitoring in children in order to improve long-term outcomes.

Abstract
OBJECTIVES To evaluate a large anti-tumor necrosis factor (TNF)-treated pediatric inflammatory bowel disease cohort for drug-induced liver injury (DILI) following presentation of an index case with suspected DILI with autoimmune features after infliximab exposure. To characterize the incidence, natural history, and risk factors for liver enzyme elevation with anti-TNF use. STUDY DESIGN We reviewed the index case and performed a retrospective cohort study of 659 children receiving anti-TNF therapy between 2000 and 2015 at a tertiary pediatric inflammatory bowel disease center. Patients with alanine aminotransferase (ALT) ≥×2 the upper limit of normal were included. The incidence, evolution, and risk factors for liver injury were examined with univariate and multivariable proportional hazards regression. Causality was assessed using the Roussel-Uclaf Causality Assessment Method. RESULTS The index case, a teenage girl with Crohn's disease, developed elevated liver enzymes and features of autoimmune hepatitis on liver biopsy 23 weeks after starting infliximab. The injury resolved entirely within 4 months of withdrawing infliximab without additional therapy. Overall, 7.7% of our cohort developed new ALT elevations while on anti-TNF. Most ALT elevations were mild and transient and attributable to alternate etiologies. No additional clear cases of autoimmune hepatitis were identified. CONCLUSIONS Transient liver enzyme abnormalities are relatively common among anti-TNF-treated children. Anti-TNF-related DILI with autoimmune features is rare but must be recognized so that therapy can be stopped.

Abstract
OBJECTIVES Discrepancies between inflammatory bowel disease (IBD) endoscopic/histological extent are documented at diagnosis. It is unclear whether these differences persist through disease course, with potential impact on categorization and management. We aimed to analyze the progression of disease over a 3-year period. METHODS Patients younger than 17 years, diagnosed between 2010 and 2013 at Southampton Children's Hospital and followed-up for 3 years were eligible. Primary outcome was disease extent at diagnosis and follow-up. Data are presented as percentage of patients undergoing endoscopy. Paris classification (PC) and PC using histological, rather than endoscopic disease, were determined. RESULTS One hundred and twenty-five patients were included, 66 boys; Crohn's disease (CD) 74, ulcerative colitis (UC) 40, IBD unclassified (IBDU) 11. All had endoscopy at diagnosis. One hundred and two patients underwent ≥1 repeat endoscopies.Disease extent reduced from diagnosis to first follow-up endoscopy for both endoscopic and histological disease extent (CD/UC/IBDU, all P < 0.00006). Histological extent remained greater than endoscopic in CD with significant differences in stomach, ileum, and large bowel at all follow-up points (P = < 0.045). Endoscopic matched histological extent in UC/IBDU. Applying a modified PC resulted in significant changes for CD (L3 27.4%-53.2%, P = 0.006, L3 + L4A 21%-50%, P = 0.001, and upper gastrointestinal disease 50%-80.6%, P = 0.0006) but not UC. CD height (-0.37 to -0.25) and weight (-1.09 to -0.19) standard deviation scores increased from diagnosis to follow-up. CONCLUSIONS Histological disease is greater than endoscopic extent at diagnosis and during follow-up in CD, although not in UC/IBDU. Classification of disease extent in CD should be based on both endoscopic and histological criteria.

Abstract
Inflammatory bowel disease (IBD) includes 2 chronic idiopathic inflammatory diseases: ulcerative colitis and Crohn disease. The incidence and prevalence of IBD is increasing worldwide. It can affect people of all ages, including children and geriatric populations, and can impact all aspects of life. In this article, diagnosis and treatment of IBD in adults, pediatric, pregnant, and elderly populations are explored from the perspective of a primary care physician.

Abstract
PURPOSE OF REVIEW After expiry of the patent of originator anti-tumor necrosis factor drug infliximab (Remicade), CT-P13 was in 2013 the first infliximab biosimilar to be approved by the European Medicine Agency (EMA) for the same indications as the reference drug, including paediatric inflammatory bowel disease (IBD). The approval was based on extrapolation, after extensive in-vitro studies and clinical experience in patients with ankylosing spondylitis and rheumatoid arthritis. The extrapolation of CT-P13 to IBD and to paediatric patients raised concerns among paediatric IBD specialists. RECENT FINDINGS Now, almost 4 years later, we can conclude that those concerns have been resolved. There are a growing number of postmarketing studies and real-life data, so far mostly in adults and some in children with IBD. These studies show reassuring comparable efficacy, safety and immunogenicity between CT-P13 and the reference Infliximab. CONCLUSION In Europe, biosimilars are increasingly regularly prescribed drugs in paediatric IBD. Due to their lower cost, treatment expenses have gone down considerably (up to 30% or more in some countries) and patient access has improved. However, additional well designed studies to investigate long term follow-up of biosimilars in children are still needed. In addition, clinical studies addressing pharmacokinetics, pharmacodynamics and optimal use of infliximab (originator as well as biosimilar) are still desirable.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gut characterised by alternating periods of remission and relapse. Whilst the mechanism underlying this disease is yet to be fully understood, old and newer generation treatments can only target selected pathways of this complex inflammatory process. This narrative review aims to provide an update on the most recent advances in treatment of paediatric IBD. A MEDLINE search was conducted using “paediatric inflammatory bowel disease”, “paediatric Crohn’s disease”, “paediatric ulcerative colitis”, “treatment”, “therapy”, “immunosuppressant”, “biologic”, “monitoring” and “biomarkers” as key words. Clinical trials, systematic reviews, and meta-analyses published between 2014 and 2016 were selected. Studies referring to earlier periods were also considered in case the data was relevant to our scope. Major advances have been achieved in monitoring the individual metabolism, toxicity and response to relevant medications in IBD including thiopurines and biologics. New biologics acting on novel mechanisms such as selective interference with lymphocyte trafficking are emerging treatment options. Current research is investing in the development of reliable prognostic biomarkers, aiming to move towards personalised treatments targeted to individual patients.
