Abstract
The transition of young patients with inflammatory bowel disease (IBD) from pediatric to adult-centered healthcare presents a significant challenge, particularly in regions like Oman, where transfer occurs as early as 14 years old. Although both pediatric and adult patients require multidisciplinary management, key differences in disease characteristics, vaccination needs, growth considerations, and treatment approaches necessitate a carefully structured transition process. Effective communication between pediatric and adult gastroenterologists is crucial for ensuring optimal management for these young patients. This mini-review explores the complexities involved in transitioning young patients with IBD to adult healthcare services.

Abstract
BACKGROUND/OBJECTIVES Growth in childhood and adolescence is influenced by a complex interaction of genetic, environmental, and hormonal factors, with growth hormone (GH) and insulin-like growth factor 1 (IGF-1) playing crucial roles in linear growth and development. However, chronic inflammation, often detected in situations like inflammatory bowel disease and juvenile idiopathic arthritis, can significantly disrupt the GH/IGF-1 axis, causing a relevant growth impairment. METHODS We conducted a retrospective review focusing on the role of cytokines in the GH-IGF-1 axis and growth. RESULTS Inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 have been shown to contribute to GH resistance through an array of mechanisms that involve the downregulation of GH receptors and alterations in IGF-1 metabolism. This disruption negatively impacts the growth plate, particularly by impairing chondrocyte proliferation and differentiation, which are essential for proper bone elongation. This review delves into the intricate relationship among growth, chronic inflammation, and GH-IGF-1 axis, emphasizing the contribution of inflammatory cytokines in modulating GH signaling. It also highlights how cytokines can interfere with the molecular pathways that regulate skeletal growth, ultimately leading to growth disturbances in children suffering from chronic inflammatory diseases. CONCLUSIONS The findings underscore the importance of controlling inflammation in affected individuals to mitigate its detrimental effects on growth and ensure that children may reach their growth full potential.

Abstract
BACKGROUND AND AIMS Treatment guidelines for paediatric Crohn's disease [CD] suggest early use of anti-tumour necrosis factor alpha [anti-TNFα] in high-risk individuals. The aim is to evaluate the effect of early anti-TNF in a real-world cohort. METHODS Children with newly diagnosed CD were prospectively recruited at 28 participating sites of the international observational PIBD-SETQuality study. Outcomes were compared at 3 months, 1 and 2 years between patients receiving early anti-TNF [<90 days after diagnosis] and those not receiving early anti-TNF. Outcomes included sustained steroid-free remission [SSFR] without treatment intensification [specified as SSFR*] and sustained steroid-free mild/inactive disease without treatment intensification [specified as SSFMI*]. Penalised logistic regression model-based standardisation was applied to estimate the relative risks [RR] of early therapy on outcomes. RRs were estimated for high-risk and low-risk patients, based on presence of predictors of poor outcome [POPOs] and disease activity at diagnosis. RESULTS In total, 331 children (median age 13.9 years [IQR 12.2-15.3]) were enrolled, with 135 [41%] receiving early anti-TNF. At 1 year, patients on early anti-TNF had higher rates of SSFR* [30% vs 14%, p <0.001] and SSFMI* [69% vs 33%, p <0.001], with RRs of 2.95 [95% CI 1.63-5.36] and 4.67 [95% CI 2.46-8.87], respectively. At 1 year, the RRs for SSFMI* were higher, and statistically significant in high-risk patients, i.e. those with moderate/severe disease compared with mild/inactive disease at diagnosis (5.50 [95% CI 2.51-12.05] vs 2.91 [95% CI 0.92-9.11]), and those with any POPO compared with no POPO (5.05 [95% CI 2.45-10.43] vs 3.41 [95% CI 0.54-21.7]). CONCLUSION In this cohort of children with newly-diagnosed CD, early anti-TNF demonstrated superior effectiveness in high-risk patients.

Factors Associated with Reaching Mid-Parental Height in Patients Diagnosed with Inflammatory Bowel Disease in Childhood and Adolescent Period. Gut Liver 2024; 18:106-115. [PMID: 37638380 PMCID: PMC10791497 DOI: 10.5009/gnl220421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 02/01/2023] [Accepted: 04/06/2023] [Indexed: 08/29/2023] Open
Abstract
BACKGROUND/AIMS The recent update on the Selecting Therapeutic Targets in Inflammatory Bowel Disease initiative has added normal growth in children as an intermediate target in Crohn's disease and ulcerative colitis. We aimed to investigate factors associated with reaching mid-parental height (MPH) in patients diagnosed with inflammatory bowel disease in childhood and the adolescent period. METHODS This multicenter retrospective observational study included pediatric patients with inflammatory bowel disease that had reached adult height. Factors associated with reaching MPH were investigated by logistic regression analyses. RESULTS A total of 166 patients were included in this study (128 Crohn's disease and 38 ulcerative colitis). Among them, 54.2% (90/166) had reached their MPH. Multivariable logistic regression analysis revealed that height Z-score at diagnosis and MPH Z-score were independently associated with reaching MPH (odds ratio [OR], 8.45; 95% confidence interval [CI], 4.44 to 17.90; p<0.001 and OR, 0.11; 95% CI, 0.04 to 0.24; p<0.001, respectively). According to the receiver operating characteristic curve analysis, the optimal cutoff level of "height Z-score at diagnosis minus MPH Z-score" that was associated with reaching MPH was -0.01 with an area under the curve of 0.889 (95% CI [0.835 to 0.944], sensitivity 88.9%, specificity 84.2%, positive predictive value 87.0%, negative predictive value 86.5%, p<0.001). CONCLUSIONS Height Z-score at diagnosis and MPH Z-score were the only factors associated with reaching MPH. Efforts should be made to restore growth in pediatric patients who present with a negative "height Z-score at diagnosis minus MPH Z-score."

Abstract
BACKGROUND There is increasing recognition that children with Crohn's Disease (CD) can develop obesity. METHODS Using the RISK Study, an inception cohort of pediatric CD participants, and Bone Mineral Density in Childhood Study (BMDCS), a longitudinal cohort of healthy children, multivariable linear mixed effects, generalized linear mixed effects, and logistic regression models were used to evaluate factors associated with change in body mass index z-score (BMIZ), obesity, and excessive weight gain, respectively. RESULTS 1029 CD participants (625 exposed to antitumor necrosis factor (anti-TNF) therapy) and 1880 healthy children were included. Change in BMIZ was higher in CD exposed to anti-TNF as compared to CD unexposed to anti-TNF and the healthy reference group. Sex, age, baseline BMIZ, C-reactive protein, anti-TNF, and steroids were associated with changes in BMIZ in CD. CD exposed (odds ratio [OR] 4.81, confidence interval [CI] 4.00-5.78) and unexposed (OR 3.14, CI 2.62-3.76) had a greater likelihood of becoming obese versus the healthy reference group. While the prevalence of obesity was higher at baseline in the healthy reference group (21.3%) versus CD participants (8.5% exposed vs. 11.1% unexposed), rates of obesity were similar by the end of follow-up (21.4% healthy vs. 20.3% exposed vs. 22.5% unexposed). Anti-TNF therapy was an independent risk factor for the development of obesity and excessive weight gain in CD participants. CONCLUSIONS Patients with CD have dynamic changes in BMIZ over time, and while for most, this is restorative, for some, this can lead to obesity and excessive weight gain. It is important to understand the factors that may lead to these changes, including anti-TNF therapy. Counseling of patients and early lifestyle intervention may be necessary.

Abstract
BACKGROUND Growth is an important clinical outcome, especially in childhood-onset inflammatory bowel disease (IBD). Prior research has demonstrated growth improvements with infliximab therapy. There are limited studies evaluating whether clinical and growth outcomes in children initiated on the infliximab originator and infliximab biosimilar are similar. METHODS This was a single-center retrospective review of patients with IBD, younger than 17 years old, and initiated on the infliximab originator or biosimilar for at least 12 months between April 2016 and February 2021. Propensity score matching was utilized. Laboratory values, disease activity scores, and growth values were collected at baseline (prior to infliximab initiation), 6 months, and 12 months post initiation. Linear mixed models with random intercepts were used to test differences in measures over time and between study groups. RESULTS There were 113 patients on the originator and 39 patients on a biosimilar who met eligibility criteria. Propensity score methodology identified 37 dyads (1:1 match). Weight, height, and body mass index z scores increased over time (from baseline to 12 months) for both groups ( P < 0.05) and there was a similar rate of change between study groups. Clinical outcomes of lab values (albumin, C-reactive protein, and hemoglobin) and disease activity scoring were similar from baseline to 12 months between study groups. CONCLUSIONS There were similar improvements in growth and clinical outcomes in patients initiated on the infliximab originator compared to an infliximab biosimilar agent. This study adds to the limited research evaluating whether infliximab biosimilars have similar growth outcomes in children with IBD.

Abstract
Vitamin D can not only regulate calcium and phosphorus metabolism, but also exert an immunoregulatory effect. Vitamin D deficiency is common in patients with Crohn's disease (CD). Studies have shown that vitamin D is associated with CD and other autoimmune diseases and can improve the condition of patients with CD and promote their recovery by regulating intestinal immunity, repairing the intestinal mucosal barrier, inhibiting intestinal fibrosis, enhancing the response to infliximab, and regulating intestinal microbiota. Exogenous vitamin D supplementation can induce disease remission while increasing the serum level of vitamin D. However, only a few randomized, double-blind, and placebo-controlled trials have investigated the therapeutic effect of vitamin D in CD, and the optimal form of vitamin D supplementation, the specific dosage of vitamin D supplementation, and the optimal serum maintenance concentration of vitamin D remain to be clarified. This article mainly discusses the mechanism of action of vitamin D in CD and the beneficial effect of exogenous vitamin D supplementation on CD.

Abstract
OBJECTIVES We investigated the therapeutic drug monitoring of adalimumab (ADL) on clinical remission (CR) and mucosal healing (MH) rates in paediatric patients with Crohn disease (CD). Furthermore, long-term treatment efficacy of ADL in paediatric CD was evaluated through 3-year follow-up. METHODS We conducted a prospective study of 31 patients with CD who received ADL maintenance therapy and underwent endoscopic evaluation of MH and pharmacokinetic analysis. Patients in CR were identified based on Paediatric Crohn Disease Activity Index (PCDAI) scores less than 10. Patients with MH were identified based on Simple Endoscopic Scores for Crohn Disease (SES-CD) of less than 2. RESULTS At 4 months and 1 year of ADL treatment, 28 and 26 patients, respectively, were under CR; 13 and 17 patients, respectively, achieved MH. The median trough levels (TLs) of ADL were higher in patients in CR (7.6 ± 3.5 μg/mL) than in patients with active disease (5.1 ± 2.2 μg/mL). ADL TLs were significantly higher in patients who achieved MH than in those who did not (14.2 ± 7.6 vs 7.8 ± 5.2 μg/mL). The optimal cut-point for predicting MH at 1 year of ADL treatment was 8.18 μg/mL. During long-term follow-up, ADL TLs were stably maintained over 10 μg/mL; not only CR and MH but also histologic remission was obtained at a high rate. ADL administration maintained a positive effect on growth during the maintenance period. CONCLUSIONS ADL TLs were significantly higher in paediatric patients with CD who achieved CR or MH. ADL treatment showed long-term stable efficacy and positive effects on growth indicators.

Abstract
To further explore genetic links between complex traits, we developed a comprehensive framework to harmonize and integrate extensive genotype and phenotype data from the four well-characterized cohorts with the focus on cardiometabolic diseases deposited to the database of Genotypes and Phenotypes (dbGaP). We generated a series of polygenic risk scores (PRS) to investigate pleiotropic effects of loci that confer genetic risk for 19 common diseases and traits on body height, type 2 diabetes (T2D), and myocardial infarction (MI). In a meta-analysis of 20,021 subjects, we identified shared genetic determinants of Crohn's Disease (CD), a type of inflammatory bowel disease, and body height (p = 5.5 × 10-5). The association of PRS-CD with height was replicated in UK Biobank (p = 1.1 × 10-5) and an independent cohort of 510 CD cases and controls (1.57 cm shorter height per PRS-CD interquartile increase, p = 5.0 × 10-3 and a 28% reduction in CD risk per interquartile increase in PRS-height, p = 1.1 × 10-3, with the effect independent of CD diagnosis). A pathway analysis of the variants overlapping between PRS-height and PRS-CD detected significant enrichment of genes from the inflammatory, immune-mediated and growth factor regulation pathways. This finding supports the clinical observation of growth failure in patients with childhood-onset CD and demonstrates the value of using individual-level data from dbGaP in searching for shared genetic determinants. This information can help provide a refined insight into disease pathogenesis and may have major implications for novel therapies and drug repurposing.

Abstract
BACKGROUND Tumour necrosis factor (TNF)-α inhibitors have been widely used for the treatment of moderate-to-severe inflammatory bowel disease (IBD). TNFα also plays an important role in the regulation of weight homeostasis and metabolism and has been linked to variations in anthropometric responses. This relationship in patients with IBD has yet to be determined. OBJECTIVES Our objective was to evaluate the effects of TNFα inhibitors on changes in anthropometric measures in both adults and children with IBD through a systematic review and meta-analysis. METHODS Multiple database searches identified studies involving children and adults with IBD and treated with TNFα inhibitors and reporting at least one primary outcome measure. Where possible, data were combined for meta-analysis. The primary outcomes included weight, body mass index (BMI), waist circumference, height, height/velocity, and fat and lean mass. Secondary outcomes included surrogate markers of disease activity. A random-effects model was used to estimate the standardised mean difference (SMD). RESULTS In total, 23 cohort studies (total 1167 participants) met the inclusion criteria. Meta-analysis was performed on 13 of these studies. In children, 6-29.3 months of anti-TNFα therapy had a small but statistically significant effect on weight (SMD 0.31; 95% confidence interval [CI] 0.12-0.49; P = 0.001) with a mean gain in z score of 0.30 (standard error [SE] 0.12). In adults, 2-22.4 months of treatment had a moderate effect on BMI (SMD 0.72; 95% CI 0.17-1.26; P = 0.010; mean gain 1.23 kg/m2; SE 0.21). A small but statistically significant increase in BMI z score was found in children (SMD 0.28; 95% CI 0.03-0.53; P = 0.026; mean change 0.31 ± standard deviation [SD] 0.14) after 12-29.3 months of therapy. A meta-analysis of four studies found a negligible but statistically significant increase in height (SMD 0.16; 95% CI 0.06-0.26; P = 0.002; mean change 0.17 z score [SE 0.05]). A negligible effect on fat mass (SMD 0.24; 95% CI -0.19-0.66; P = 0.272) was found in a meta-analysis of five studies. Of note, despite the high heterogeneity among the studies that addressed the issue, these results were also consistently supported by findings from studies not included in the meta-analysis and reviewed in the systematic review. Unfortunately, a lack of data meant we were unable to perform moderator analysis on observed heterogeneity. CONCLUSION Anti-TNFα treatment appears to be associated with an increase in body weight, BMI, and other anthropometric parameters. Given the differing courses of IBD between children and adults, this association should be considered before initiating biologics for undernourished, overweight, and obese patients.

Abstract
OBJECTIVES Growth impairment is common in children with Crohn disease (CD). We aimed to assess the effect of adalimumab (ADL) treatment on linear growth in children with CD in a post-hoc analysis of the Pediatric Crohn's Disease AdalImumab Level-based Optimization Treatment randomized controlled trial. METHODS Children 6 to 17 years who responded to ADL induction were assessed consecutively for anthropometric parameters. Associations of these parameters with disease characteristics and disease activity were analyzed. RESULTS Overall, 66 patients completed 72 weeks of follow-up (25% girls, mean age of 15.6 ± 2.5 years). Median (interquartile range [IQR]) height z score improved from -0.6 (-1.6-0.15) at baseline to -0.33 (-1.3-0.5) at week 72 (P = 0.005) with lesser improvement in patients with perianal disease. Similar effect was noted in children with growth potential (boys younger than 16 years, girls younger than 14 years). Median (IQR) height velocity standard deviation was -0.32 (-1.5-0.8) at week 26, and +0.11 (-1.1-1.3) at week 72. Median weight z score increased from -0.54 (-1.2-0.15) to -0.1 (-0.9-0.6), P < 0.001 and body mass index from -0.4 (-1.0-0.5) to 0.0 (-0.8-0.9), P = 0.005. Pediatric CD activity index and erythrocyte sedimentation rate at week 4 correlated negatively with height z score changes (P = 0.043 and P = 0.048, respectively), whereas sustained clinical and biologic remission (week 4-72) were positively associated with changes in height z scores. Significant improvement in linear growth was predicted by lower pediatric CD activity index and erythrocyte sedimentation rate at the end of induction and sustained clinical remission (P = 0.05) and sustained normal C-reactive protein (P = 0.001) at all visits. CONCLUSION In children with moderate-to-severe CD, ADL treatment had a significant effect on linear growth, with normalization of weight and body mass index (clinicaltrials.gov no: NCT02256462).

Abstract
BACKGROUND & AIMS We aim to provide guidance for medical treatment of luminal Crohn's disease in children. METHODS We performed a systematic search of publication databases to identify studies of medical management of pediatric Crohn's disease. Quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach. We developed statements through an iterative online platform and then finalized and voted on them. RESULTS The consensus includes 25 statements focused on medical treatment options. Consensus was not reached, and no recommendations were made, for 14 additional statements, largely due to lack of evidence. The group suggested corticosteroid therapies (including budesonide for mild to moderate disease). The group suggested exclusive enteral nutrition for induction therapy and biologic tumor necrosis factor antagonists for induction and maintenance therapy at diagnosis or at early stages of severe disease, and for patients failed by steroid and immunosuppressant induction therapies. The group recommended against the use of oral 5-aminosalicylate for induction or maintenance therapy in patients with moderate disease, and recommended against thiopurines for induction therapy, corticosteroids for maintenance therapy, and cannabis in any role. The group was unable to clearly define the role of concomitant immunosuppressants during initiation therapy with a biologic agent, although thiopurine combinations are not recommended for male patients. No consensus was reached on the role of aminosalicylates in treatment of patients with mild disease, antibiotics or vedolizumab for induction or maintenance therapy, or methotrexate for induction therapy. Patients in clinical remission who are receiving immunomodulators should be assessed for mucosal healing within 1 year of treatment initiation. CONCLUSIONS Evidence-based medical treatment of Crohn's disease in children is recommended, with thorough ongoing assessments to define treatment success.

Abstract
PURPOSE Pediatric Crohn's disease (CD) is directly related to growth and has a high probability of requiring surgical intervention(s); therefore, more active treatment for CD is required for children. This study investigated the impact of biologics on growth and disease course associated with surgery. METHODS This was a retrospective cohort study involving patients diagnosed with CD at the Seoul National University Children's Hospital (Seoul, Korea) between January 2006 and October 2017. The aim was to determine the characteristics of pediatric patients with CD and whether biologics affected growth and the surgical disease course. RESULTS Among patients who underwent surgery for CD, the mean number of operations per patient was 1.89. The mean time from initial diagnosis to surgery was 19.3 months. The most common procedure was fistulectomy (34%), followed by incision and drainage (25%). In all patients, the use of biologics increased the height (p=0.002) and body mass index (BMI) (p=0.005). Among patients who underwent surgery, height (p=0.004) and BMI (p=0.048) were increased in the group using biologics. Patients who used biologics exhibited a low operation rate only within 2 years after diagnosis, with no differences thereafter (p=0.027). CONCLUSION Although biologics could not mitigate the operation rate in pediatric patients who underwent surgery for CD, biological therapy delayed disease progression within 2 years of disease onset. Additionally, biologics conferred growth and BMI benefits in this window period. Therefore, it may be helpful to use biologics for optimal growth in pediatric patients with a high probability of undergoing future surgery.

Abstract
Pharmacologic treatment of children and adolescents with inflammatory bowel diseases (IBD) [Crohn's disease and ulcerative colitis] requires consideration of disease and medication effects on growth and nutrition, the importance of durability of biologics, and concerns for long-term sequelae of disease and therapies. Achieving early remission in children with Crohn's disease correlates with improved outcomes and therefore allows a window of opportunity for maximizing growth. Thus, there is a great need to treat children and adolescents with the right drug at the right time while achieving adequate exposure. Improved understanding of disease phenotypes, disease natural history, and risk stratification will play a critical role in treatment selection for children, particularly as more therapeutic options become available. Here we summarize data supporting newer concepts of treating the individual child with IBD through targeted early biologic treatment, including utilization of therapeutic drug monitoring to optimize treatment effects and the use of early antitumor necrosis factor (TNF)-α therapies to mitigate long-term sequelae of the disease. Recent inception cohort studies provide important data regarding the risk stratification of children and adolescents with IBD, which support a move toward a personalized therapeutic approach to IBD in children and adolescents.

Abstract
The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient's developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients' knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients' adherence to therapy, maintain the appropriate health status, improve patients' self-management, and promote self-reliance among patients.

Abstract
Impairment of growth is recognized as one of the most significant complications of inflammatory bowel disease (IBD) in pediatric patients. The reported incidence of growth failure at diagnosis is 15-40% in pediatric onset Crohn's disease (CD) and 3-10% in ulcerative colitis (UC). Growth failure is associated with decreased appetite, abdominal symptoms, malabsorption due to mucosal inflammation, growth hormone (GH) resistance due to inflammation, and even genetic factors. Several population-based studies and cohort studies suggest that patients with pre-pubertal onset CD have a higher risk of growth failure at disease onset. Final adult height is still lower than that of healthy controls; however, its prevalence is generally lower than that at the disease onset. Several IBD treatments were reported to improve patients' growth. In addition to enteral nutrition therapy, treatment with anti-tumor necrosis factor (TNF) agents was reported to have favorable effects on growth of patients with pre-pubertal onset CD. Avoiding corticosteroids (CS) and achieving deep remission seems to be important to maintain optimal growth in patients with pediatric onset IBD.

Abstract
The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient’s developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients’ knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients’ adherence to therapy, maintain the appropriate health status, improve patients’ self-management, and promote self-reliance among patients.

Abstract
Background/Aims Information regarding the efficacy of early infliximab treatment in pediatric patients with Crohn’s disease (CD) is limited. We aimed to evaluate the impact of early combined immunosuppression on linear growth in pediatric patients with CD by performing step-up comparisons. Methods This retrospective study included pediatric patients with moderate-to-severe CD, who received a combination therapy with infliximab and azathioprine for at least 3 years and sustained corticosteroid-free remission without loss of response. The z-scores of the growth indicators obtained at the time of diagnosis and annually for 3 years thereafter were compared between the two groups. Results The early combined immunosuppression group displayed significantly increased linear growth 3 years after diagnosis (p=0.026). A significant difference was also observed in the linear growth 3 years after diagnosis between subgroups of Tanner stages 1–2 (p=0.016). Conclusions The early introduction of biologics should be considered to improve linear growth in pediatric patients with CD.

Abstract
The emergence of mucosal healing as a treatment goal that could modify the natural course of Crohn's disease and the accumulating evidence showing that biologics are most effective in achieving mucosal healing, along with the success of early treatment regimens for rheumatoid arthritis, have led to the identification of early Crohn's disease and development of the concept of catching the therapeutic window during the early disease course. Thus, an increasing number of pediatric gastroenterologists are adopting an early biologic treatment strategy with or without an immunomodulator. Although early biologic treatment is effective, cost and overtreatment are issues that limit its early use. Currently, there are insufficient data on who will benefit most from early biologics, as well as on who will not need early or even any biologics. For now, top-down biologics should be considered for patients with currently known high-risk factors of poor outcomes. For other patients, close, objective monitoring and accelerating the step-up process by means of a treat-to-target approach seems the best way to catch the therapeutic window in early pediatric Crohn's disease. The individual benefits of immunomodulator addition during early biologic treatment should be weighed against its risks and decision on early combination treatment should be made after comprehensive discussion with each patient and guardian.

Abstract
BACKGROUND Children with active inflammatory bowel disease (IBD) are frequently underweight. Anti-tumor necrosis factor (anti-TNF) agents may induce remission and restore growth. However, its use in other autoimmune diseases has been associated with excess weight gain. Our aim was to examine whether children with IBD could experience excess weight gain. METHODS A centralized diagnostic index identified pediatric IBD patients evaluated at our institution who received anti-TNF therapy for at least 1 year between August 1998 and December 2013. Anthropometric data were collected at time of anti-TNF initiation and annually. Excess weight gain was defined as ΔBMI SDS (standard deviation score) where patients were (1) reclassified from "normal" to "overweight/obese," (2) "overweight" to "obese," or (2) a final BMI SDS >0 and ΔSDS >0.5. RESULTS During the study period, 268 children received anti-TNF therapy. Of these, 69 had sufficient follow-up for a median of 29.3 months. Median age at first anti-TNF dose was 12.8 years. At baseline, mean weight SDS was -0.7 (SD 1.4), while mean BMI SDS was -0.6 (1.3). Using baseline BMI SDS, 11.6% were overweight/obese. At last follow-up (LFU), however, the mean ΔBMI SDS was 0.50 (p < 0.0001). However, 10 (17%) patients had excess weight gain at LFU; 3 patients were reclassified from "normal" to "obese," and 7 had a final BMI SDS >0 and ΔSDS >0.5. CONCLUSIONS Pediatric patients with IBD may experience excess weight gain when treated with anti-TNF agents. Monitoring for this side effect is warranted.

Abstract
INTRODUCTION In most European countries, an infliximab biosimilar (CT-P13) is currently in common use. In vitro and in vivo studies have proved a high similarity between CT-P13 and the reference infliximab. CT-P13 was licensed for use in patients with Crohn disease (CD) based on the extrapolation of data from preclinical studies and clinical trials in rheumatology indications. The aim of this study was to assess the similarity between CT-P13 and the originator infliximab in induction therapy in CD paediatric patients. METHODS Thirty-six CD paediatric patients from 3 Polish academic centres who started biological therapy with CT-P13 were enrolled in this prospective, observational study. Patients received 3 induction doses (5 mg/kg) of CT-P13 at weeks 0, 2, 6. Assessment was performed before the first infusion and at week 14. RESULTS Overall 34/36 (94.4%) patients completed induction therapy with CT-P13. A clinical response or remission after 3 initial doses was achieved in 31/36 (86%) and 24/36 (67%) of patients, respectively. Clinically and statistically significant decreases in Paediatric Crohn's Disease Activity Index, C-reactive protein, and erythrocyte sedimentation rate were observed in the responders group. An allergic reaction during infusion, which led to treatment discontinuation, was observed in one case. CONCLUSIONS Induction therapy with CT-P13 in children with CD is effective. The profile appears similar to that reported for the reference infliximab. No unexpected adverse events occurred.

Abstract
Objective To determine whether reduced growth velocity (GV) in extremely low birth weight infants is preceded by elevated inflammatory cytokines. Study Design GV was determined at 36 weeks' postmenstrual age (PMA) in 768 infants 401 to 1,000 g birth weight (BW). Association between blood cytokines measured through day of life 21 and GV was explored using linear regression models that adjusted for late-onset sepsis (LOS), BW, small for gestational age (SGA), gender, race, energy intake, and center. Results Serum interleukin-6 (IL-6) was increased at days 14 and 21 in LOS infants. LOS was associated with reduced energy intake and GV for weight (weight-GV) at 36 weeks' PMA. Linear regression analysis controlling for LOS and energy intake showed significant relationships between increased IL-6 at days 14 and 21 with reduced weight-GV at 36 weeks' PMA (p < 0.0001). The relationship between day 21 IL-6 and weight-GV was not associated with LOS (p = 0.12) when controlling for BW and energy intake. Both BW (p = 0.02) and energy intake (p = 0.003) influenced the relationship between day 14 IL-6 and weight-GV. Conclusion IL-6 elevation during the first month of life is associated with lower weight-GV at 36 weeks' PMA and may have a direct effect upon energy balance and postnatal growth.

Abstract
BACKGROUND Growth failure is well-recognized in pediatric inflammatory bowel disease (PIBD; <18 years). We aimed to examine whether antitumor necrosis factor (TNF) therapy improves growth in a PIBD population-based cohort. METHODS A retrospective review of all Scottish children receiving anti-TNF (infliximab [IFX] and adalimumab [ADA]) from 2000 to 2012 was performed; height was collected at 12 months before anti-TNF (T-12), start (T0), and 12 (T+12) months after anti-TNF. RESULTS Ninety-three of 201 treated with IFX and 28 of 49 with ADA had satisfactory growth data; 66 had full pubertal data. Univariate analysis demonstrated early pubertal stages (Tanner 1-3 n = 44 vs T4-5 n = 22), disease remission, disease duration ≥2 years, and duration of IFX ≥12 months were associated with improved linear growth for IFX; for ADA only improvement was seen in Tanner 1-3. For IFX, Tanner 1-3 median Δ standard deviation scores for height (Ht SDS) -0.3 (-0.7, 0.2) at T0 changed to 0.04 (-0.5, 0.7) at T+12 (P < 0.001) versus -0.01 (-0.5, 0.9) at T0 in T4-5 changed to -0.01 (-0.4, 0.2) at T+12 (P > 0.05). For IFX disease duration ≥2 year, median Δ Ht SDS was -0.13 (-0.6, 0.3) at T0 then 0.07 (-0.3, 0.6) at T+12 (P < 0.001). Remission improved Δ Ht SDS (median Δ Ht SDS -0.14 [-0.6, 0.3] at T0 to 0.17 [-0.2, 0.7] at T+12 [P < 0.001]). Multiple regression analysis demonstrated corticosteroid usage at T0 predicted improved Δ Ht SDS at T+12 for IFX and ADA. CONCLUSIONS Anti-TNF therapy is more likely to be associated with growth improvement when used at earlier stages of puberty with remission a key growth-promoting strategy in pediatric Crohn disease.

Abstract
Inflammation contributes to growth failure associated with inflammatory bowel diseases. Anti-TNFα therapy induces sustained remission and short-term improvements in height velocity and/or height standard deviation score (H-SDS) patients with Crohn's disease. The purpose of this study was to evaluate growth and adult height in patients with Crohn's disease taking maintenance infliximab or adalimumab therapy.This university-hospital based retrospective study included 61 patients, with a median follow-up of 2.6 years (2.0; 3.3). 38 patients (62%) reached their adult height. H-SDS was collected at diagnosis and together with disease activity markers (Harvey-Bradshaw Index, albumin, and C-reactive protein) at treatment initiation (baseline), and follow-up completion. Wilcoxon's signed-rank test was chosen for comparisons. Median H-SDS decreased from diagnosis to baseline (-0.08 [-0.73; +0.77] to -0.94 [-1.44; +0.11], p<0.0001) and then increased to follow-up completion (-0.63 [-1.08; 0.49], p = 0.003 versus baseline), concomitantly with an improvement in disease activity. Median adult H-SDS was within the normal range (-0.72 [-1.25; +0.42]) but did not differ from baseline H-SDS and was significantly lower than the target H-SDS (-0.09 [-0.67; +0.42], p = 0.01). Only 2 (6%) males had adult heights significantly below their target heights (10.5 and -13.5 cm [-1.75 and -2.25 SD]). In conclusion, anti-tumor necrosis factor α (TNF) therapy prevented loss of height without fully restoring the genetic growth potential in this group of patients with CD. Earlier treatment initiation might improve growth outcomes in these patients.

Abstract
BACKGROUND Growth impairment remains a major concern in children with Crohn's disease, but evidence remains unclear, in particular, whether steroid use is implicated. We aimed to (1) determine the frequency of temporary (TGI) and permanent (PGI) growth impairment in children administered steroids and (2) examine whether cumulative steroid administration was associated with TGI and/or PGI. METHODS A retrospective cohort study was performed in patients with Crohn's disease (<18 yr) administered steroids at the gastroenterology clinics of Sainte-Justine Hospital, Montreal. Steroid dosage, height during follow-up, adult height (after age 20), and parental heights were ascertained. Patients with height z score <-1.64 on more than 1 occasion before age 18 were considered as patients with TGI. Patients with adult heights <8.5 cm below the expected target heights were considered as patients with PGI. Association between steroid dosage and TGI/PGI was studied using logistic regression analyses. Data from the Swiss IBD Cohort Study were analyzed for comparison. RESULTS A total of 221 children were studied. Approximately 19% (42/221) children were deemed as TGI, and 8/137 patients (5.8%) had PGI. TGI was associated with diagnosis at younger age (P value 0.002) and steroid administration at younger age (P value 0.001), but not with steroid dosage. Final adult height was associated with target height, but not with cumulative steroid dosage. Rates of PGI in the Swiss cohort were ∼ 9.1% in steroid users and 2.7% in nonusers. CONCLUSIONS Most children with TGI attain normal adult heights. Cumulative steroid use does not seem to be associated with either TGI or PGI in children with Crohn's disease.

Abstract
BACKGROUND AND AIMS There is growing evidence that in Crohn's disease the achievement and maintenance of mucosal healing (MH) through anti-TNFα antibodies may change the natural history of the disease. Few studies evaluating such outcome as a therapeutic goal are available in paediatrics. The primary aim of the study was to assess the efficacy of biologics in obtaining MH in a paediatric Crohn's disease cohort. The secondary aims were: (1) to assess response based on early or late treatment introduction and on combination therapy with immunomodulators versus biologics alone; and (2) to evaluate clinical outcome 2 years after the second endoscopy. METHODS Biologic-naive paediatric Crohn's disease patients starting anti-tumour necrosis factor α (TNFα) treatment were enrolled. Patients' demographic and treatment data were recorded. Clinical [Pediatric Crohn's Disease Activity Index (PCDAI)] and endoscopic [Simple Endoscopic Score for Crohn's Disease (SES-CD)] evaluations were performed at time 0 (T0) and after 9-12 months (follow-up). Appropriate induction and maintenance therapeutic schemes were applied. RESULTS Thirty-seven patients were enrolled. At enrolment, mean age was 12.3 ± 3.4 years and mean disease duration was 13.0 ± 16 months. At follow-up there was a significant decrease in PCDAI and SES-CD compared with T0 (p < 0.01). No statistical difference in frequency of MH between the early and late treatment introduction groups was found. Combination therapy was superior in obtaining complete plus partial MH (p < 0.01). One and 2 years after the second endoscopy, all and 79% of patients with complete MH and 75 and 67% of those with partial MH were still in clinical remission, respectively. CONCLUSIONS Biologics improve mucosal lesions, apparently more effectively if given in combination with immunomodulators. MH appears to sustain a better disease course.

Abstract
PURPOSE The aim of this study was to investigate the therapeutic role of an elective ileocecal resection in children with active localized Crohn's disease. METHODS This was a retrospective multicenter study which included five European referral centers which included all children with Crohn's disease who underwent ileocecal surgery from 2000 to 2011 and had a minimum of 12 months follow-up. RESULTS Altogether 68 patients fulfilled inclusion criteria. Median age at diagnosis was 13.7 years (6.6-17.9 years) and at surgery 15.2 years (8.6-18.5 years). Median duration of postoperative clinical remission was 20 months (3-95 months). Overall 54 patients (79.4%) were in remission one year after surgery and 38 (55.9%) during the total postsurgical follow up (median 30 months; range 12-95 months). Z score height for age significantly improved postoperatively in children who were at the time of surgery younger than 16 years of age (mean difference 0.232 SD; p=0.029). Cox proportional hazard regression model failed to indicate risk factors associated with postsurgical relapse. CONCLUSION Elective ileocecal resection is a valid treatment option which should be considered in a subset of pediatric patients with localized Crohn's disease with the aim of achieving clinical remission and to improve growth.

Abstract
BACKGROUND Anti-tumor necrosis factor alpha (TNFα) therapy is effective in pediatric patients with inflammatory bowel disease (IBD) but associated with a risk of developing anti-drug antibodies (ADA) which lower the efficacy. Incorporating measurement of trough levels and ADA (therapeutic drug monitoring) may prevent the development of neutralizing ADA or could contribute to more optimal treatment strategies if ADA are already formed. The aim of this review was to investigate the role of therapeutic drug monitoring in children and adolescents with IBD exposed to anti-TNFα agents. METHODS A literature search identified publications that measured anti-TNFα drug trough levels and/or ADA in children or adolescents with IBD. Studies were eligible when (1) article was written in English, (2) original data were available, (3) full text article or abstract was available, (4) measurement of antibodies against anti-TNFα drugs or trough level of anti-TNFα drugs were reported, and (5) levels were measured in pediatric patients with IBD. RESULTS The search yielded 811 articles, of which 795 articles were excluded based on title or abstract. A total of 14 studies were included in the review. CONCLUSIONS Therapeutic drug monitoring within the pediatric IBD population certainly has a potential benefit. As occurrence of immune reactions to anti-TNFα agents varies widely, incorporating measurement of IFX trough levels at week 8 or week 14 predicts therapy response and allows for dose adjustments to reach therapeutic drug concentrations. However, a clinically relevant cutoff level for ADA has not been defined yet, and the optimal intervention strategy still has to be determined.

Abstract
Adalimumab is a fully humanized anti-tumor necrosis factor alpha monoclonal antibody that was recently granted regulatory approval in the USA for the treatment of moderate to severe Crohn’s disease (CD) in children. Like infliximab, the first biologic agent used to treat pediatric CD, regulatory approval was secured many years following approval for adults. The long delay between adult and pediatric approval has led to many years of off-label use of adalimumab, although it is anticipated that the use of adalimumab may further increase with official regulatory approval. To date, pediatric literature on the use of adalimumab for treatment of CD is limited, and pediatric practitioners have mostly extrapolated from research and experience provided by the adult literature. The aim of this paper is to review the literature regarding adalimumab for the treatment of pediatric CD, and includes a review of landmark adult studies as well as the pivotal pediatric study that facilitated regulatory approval. We also discuss the role of anti-tumor necrosis factor alpha agents including adalimumab in the current treatment paradigm for pediatric CD.

Abstract
Growth failure associated with delayed puberty is a unique feature in pediatric patients with inflammatory bowel disease (IBD), especially those with Crohn's disease, which has a negative effect on quality of life, emotional functioning, social functioning, and body image. Although the underlying mechanisms are not fully clear, the condition may be induced by the effects of malnutrition, inflammatory process and glucocorticoid on the growth hormone/insulin-like growth factor-1 axis or on the growth plate. Nutrition, biologic agents, intestinal resection and glucocorticoids are main treatments. Standards for monitoring and treatment of impaired growth and development in pediatric IBD patients need to be formulated. To achieve optimal growth, the efforts of hospitals, families and society are necessary.

Abstract
BACKGROUND Management of refractory inflammatory bowel disease (IBD) in children is challenging and once response to conventional medical therapy deviates from the expected, options are often limited. Sirolimus is commonly used in post-transplantation management and is used sparsely as rescue therapy in refractory Crohn's disease. In the present study, we report the efficacy of sirolimus as an adjuvant immunosuppressive therapy in a retrospective case review of a selected group of IBD children who were refractory to the conventional treatments. METHODS Medical records of children with refractory IBD unresponsive to conventional therapy and started on sirolimus between 2006 and 2012 were retrospectively reviewed. Clinical response, through Pediatric Ulcerative Colitis Activity Index (PUCAI) and Pediatric Crohn's Disease Activity Index (PCDAI), as well as intestinal inflammation, through specific histological scores, was evaluated. RESULTS The records of 14 patients were analyzed. Eleven of them had ulcerative colitis (UC) and 3 Crohn's disease (CD); mean age at diagnosis was 9.1 years (standard deviation 3.8). Of UC patients, 5 (45%) achieved clinical remission and 2 (18%) showed clinical response. All CD patients went into clinical remission. Mucosal healing was achieved by 5 children (45%) with UC and 2 (67%) with CD patients. One child with ulcerative colitis was weaned off adalimumab, while 2 children with CD were weaned off prednisolone and methotrexate successfully. CONCLUSION Our data provide evidence that sirolimus seems to be effective as rescue therapy in a subgroup of children with severe IBD refractory to conventional therapies by inducing both clinical remission and mucosal healing.

Abstract
OBJECTIVE Pediatric Crohn's disease (CD) is often debilitating, with upper gastrointestinal (GI) involvement and complications over time. Treatment with tumor necrosis factor (TNF) blockers can induce and maintain remission. We wanted to evaluate the outcome of patients medically treated for CD to investigate whether clinical, endoscopic and biochemical factors at diagnosis are associated with the early initiation of treatment with the TNF blocker infliximab. MATERIALS AND METHODS Patients aged <18 years, diagnosed with CD were characterized according to the Porto criteria, with endoscopy, magnetic resonance imaging and biochemical tests before individual treatment. They were followed prospectively until a prescheduled examination within 2 years. RESULTS Thirty-six pediatric patients were included, 18 (50%) received infliximab. Infliximab-treated patients had shorter disease duration, more upper GI involvement (p = 0.03) and higher median C-reactive protein (CRP) (28 vs. 7.5 mg/l, p = 0.02), erythrocyte sedimentation rate (ESR) (32 vs. 18 mm/h, p = 0.01) and fecal calprotectin (1506 vs. 501 mg/kg, p = 0.01) levels. Infliximab treatment was well tolerated, and 15/18 of patients achieved clinical remission. At follow-up, 11/17 in the infliximab group and 8/13 in the non-infliximab group achieved ileocolonic mucosal healing. A majority in the infliximab group had a marked reduction of CD-specific upper GI lesions but persistence of unspecific upper GI inflammation at follow-up. CONCLUSION High levels of inflammatory markers and upper GI lesions were associated with initiation of infliximab treatment. A substantial proportion of patients still had unspecific lesions in the upper GI tract regardless of treatment. Future studies must clarify the prognostic role of persistent upper GI-involvement despite mucosal healing in the ileocolon.

Abstract
Crohn's disease in childhood causes linear growth retardation, which has a substantial effect on management of this disease. By contrast, growth is rarely a problem in children presenting with ulcerative colitis. Depending on how growth failure is defined, approximately one-third of children with Crohn's disease have growth retardation at diagnosis. Although corticosteroids can suppress growth, decreased height at diagnosis demonstrates that this finding is a consequence of the disease and not merely an adverse effect of treatment. Both inflammation and undernutrition contribute to decreased height velocity. Increased cytokine production acts both on the hepatic expression of insulin-like growth factor 1 (IGF-1) and at chondrocytes of the growth plates of long bones. Growth hormone insensitivity caused by deranged immune function is a major mechanism in growth retardation. Resolution of inflammation is the cornerstone of treatment, but current studies on growth hormone and IGF-1 might yield therapies for those children whose inflammation is refractory to treatment.

Abstract
Children and adolescents with Crohn's disease (CD) present often with a more complicated disease course compared to adult patients. In addition, the potential impact of CD on growth, pubertal and emotional development of patients underlines the need for a specific management strategy of pediatric-onset CD. To develop the first evidenced based and consensus driven guidelines for pediatric-onset CD an expert panel of 33 IBD specialists was formed after an open call within the European Crohn's and Colitis Organisation and the European Society of Pediatric Gastroenterolog, Hepatology and Nutrition. The aim was to base on a thorough review of existing evidence a state of the art guidance on the medical treatment and long term management of children and adolescents with CD, with individualized treatment algorithms based on a benefit-risk analysis according to different clinical scenarios. In children and adolescents who did not have finished their growth, exclusive enteral nutrition (EEN) is the induction therapy of first choice due to its excellent safety profile, preferable over corticosteroids, which are equipotential to induce remission. The majority of patients with pediatric-onset CD require immunomodulator based maintenance therapy. The experts discuss several factors potentially predictive for poor disease outcome (such as severe perianal fistulizing disease, severe stricturing/penetrating disease, severe growth retardation, panenteric disease, persistent severe disease despite adequate induction therapy), which may incite to an anti-TNF-based top down approach. These guidelines are intended to give practical (whenever possible evidence-based) answers to (pediatric) gastroenterologists who take care of children and adolescents with CD; they are not meant to be a rule or legal standard, since many different clinical scenario exist requiring treatment strategies not covered by or different from these guidelines.

Abstract
BACKGROUND & AIMS Many physicians hesitate to recommend anti-tumor necrosis factor (TNF) therapy for pediatric patients with inflammatory bowel disease (IBD) because of concerns about risk of infection and cancer. We performed a systematic review to quantify the incidence of serious infection, lymphoma, and death among pediatric patients with IBD who received anti-TNF therapy. These values were compared with those expected from other treatments, from adults with IBD, and from the general pediatric population. METHODS We searched MEDLINE, EMBASE, the Cochrane Collaboration, and Web of Knowledge for studies of infliximab therapy for children with ulcerative colitis or Crohn's disease, or adalimumab therapy for children with Crohn's disease. Standardized incidence ratios (SIRs) were calculated, comparing rates of infection and cancer among pediatric patients exposed to anti-TNF agents vs expected rates from pediatric patients not exposed to anti-TNF therapies or adult patients exposed to anti-TNF agents. Our analysis included 5528 patients with 9516 patient-years of follow-up evaluation (PYF). RESULTS The rate of serious infections among pediatric patients treated with anti-TNF agents (352/10,000 PYF) was similar to that of pediatric patients who received immunomodulator monotherapy (333/10,000 PYF; SIR, 1.06; 95% confidence interval [CI], 0.83-1.36), but significantly lower than the expected rate for pediatric patients treated with steroids (730/10,000 PYF; SIR, 0.48; 95% CI, 0.40-0.58) or adults treated with anti-TNF agents (654/10,000 PYF; SIR, 0.54; 95% CI, 0.43-0.67). Five treatment-related deaths occurred (4 from sepsis and 1 from arrhythmia). Two patients developed lymphoma (2.1/10,000 PYF). This value was similar to the expected rate of lymphoid neoplasia in the entire pediatric population (5.8/100,000 PYF; SIR, 3.5; 95% CI, 0.35-19.6), and lower than the population of pediatric patients receiving thiopurine monotherapy (4.5/10,000 PYF; SIR, 0.47; 95% CI, 0.03-6.44), and among adults treated with anti-TNF agents (6.1/10,000 PYF; SIR, 0.34; 95% CI, 0.04-1.51). CONCLUSIONS Based on a systematic review, the risk of lymphoma was no greater among children with IBD who received anti-TNF therapy than those treated with other IBD therapies or adults treated with anti-TNF agents. The rate of serious infection was significantly lower among pediatric patients with IBD treated with anti-TNF agents than those treated with steroids, or adults with IBD who received anti-TNF therapy.

Abstract
BACKGROUND Infliximab induces and maintains clinical remission in children with Crohn's disease (CD), but specifically pediatric long-term data remain sparse. METHODS Patients (N = 195) who received infliximab ± immunomodulator for luminal CD were retrospectively reviewed. Outcomes included clinical response, linear growth, and mucosal healing. Durability of response was assessed using Cox proportional hazards models. Levels of infliximab and antibodies (antibodies to infliximab) were measured when response was lost. RESULTS Among 195 patients (median age, 13.9 yr; median CD duration, 1.6 yr), 81% experienced complete response (judged by physician global assessment and pediatric Crohn's disease activity index ≤10). Longer duration of diagnosed CD and female gender were associated with lower response. During first year of follow-up, 35% of subjects had regimen individualized through dose escalation/interval shortening. Despite regimen optimization, 16/157 complete responders experienced loss of response at a rate of 2% to 6% per year over 5 years, associated with development of antibodies to infliximab. Concurrent immunomodulation for ≥30 weeks significantly decreased loss of response (hazard ratio = 0.25, 95% confidence interval, 0.08-0.76; P = 0.014). Follow-up endoscopic examination was performed in 40 responders, of whom 22 (73%) demonstrated complete resolution of mucosal ulceration. Patients with growth potential (Tanner 1/2 at induction) demonstrated significant improvements in mean height z-score from induction to years 1 and 2 of follow-up (P < 0.001). With infliximab initiation within the first 18 months after diagnosis, mean height z-score normalized to 0 after 3 years. CONCLUSIONS These data demonstrate sustained effectiveness of infliximab in children and adolescents with luminal CD. Durability of response is increased by concomitant immunomodulation. Clinical response is associated with enhanced linear growth, particularly when therapy is initiated early.

Abstract
Inflammatory bowel disease, particularly Crohn's disease (CD), can potentially cause growth failure during childhood as well as a reduction in final adult height. The underlying mechanism is multifactorial and includes poor nutrition, chronic inflammation, and the prolonged use of steroids. Despite major advances in the treatment of CD, current cohorts of children continue to display a deficit in linear growth and may qualify for growth-promoting hormonal therapy. However, currently there is limited evidence to support the use of endocrine therapy directed primarily at improving growth. This review is aimed at summarising the current evidence for growth impairment in inflammatory bowel disease and discusses the rationale for using growth promoting therapy.

Abstract
AIM Children with inflammatory bowel disease (IBD) have a high prevalence of growth retardation and low bone mineral density (BMD). This retrospective study investigated whether the start of infliximab treatment (IFX) was associated with improvement of growth and bone health. METHODS Anthropometry, BMD and bone markers were measured 1 year before and after the start of IFX treatment in 33 patients (51% males), with a median age of 13.5 years at baseline. Outcomes were growth with treatment and indicators of improved bone health. RESULTS Twenty-one children (64%) experienced a positive catch-up growth after IFX. Height standard deviation scores (SDS) were significantly higher in children in remission. Treatment with IFX was associated with a statistically significant increase in 25-hydroxycholecalciferol (25-OHD, p = 0.01). IFX had no influence on BMD. Children with low BMD < -2 had significantly higher inflammation scores, lower body mass index, weight, height SDS and 25-ODH after IFX. CONCLUSION After treatment with IFX, children with IBD improved significantly in weight, with the majority achieving positive catch-up growth. Bone mass tended to remain static with time of treatment with IFX, despite a significant increase in 25-OHD. Improved nutritional status positively predicts improved bone mineralisation.

Abstract
IBD includes two classic entities, Crohn's disease and ulcerative colitis, and a third undetermined form (IBD-U), characterized by a chronic relapsing course resulting in a high rate of morbidity and impaired quality of life. Children with IBD are vulnerable in terms of growth failure, malnutrition and emotional effects. The aims of therapy have now transitioned from symptomatic control to the achievement of mucosal healing and deep remission. This type of therapy has been made possible by the advent of disease-modifying drugs, such as biologic agents, which are capable of interrupting the inflammatory cascade underlying IBD. Biologic agents are generally administered in patients who are refractory to conventional therapies. However, there is growing support that such agents could be used in the initial phases of the disease, typically in paediatric patients, to interrupt and cease the inflammatory process. Until several years ago, most therapeutic programmes in paediatric patients with IBD were borrowed from adult trials, whereas paediatric studies were often retrospective and uncontrolled. However, guidelines on therapeutic management of paediatric IBD and controlled, prospective, randomized trials including children with IBD have now been published. Here, the current knowledge concerning treatment options for children with IBD are reported. We also highlight the effectiveness and safety of new therapeutic advances in these paediatric patients.

Abstract
: Anti-tumor necrosis factor agents are now considered to be a vital component of the treatment algorithm for pediatric inflammatory bowel disease. Despite the clear benefit of these agents and the realignment of treatment goals to achieve early mucosal healing, the decision to initiate therapy is often delayed due to uncertainties regarding risks and benefits. The purpose of this review was to summarize the currently available data regarding anti-tumor necrosis factor agents in pediatric inflammatory bowel disease. Specifically, we review their expected efficacy in both Crohn's disease and ulcerative colitis and the likelihood of side effects associated with these agents. In addition, we address the barriers physicians face when communicating these data and help to identify how pediatric patients and their parents can be more involved in a shared decision-making process. Through the creation of a new decision aid (Option Grid), we hope to allow for a more clear line of communication at the bedside when helping patients and parents make these difficult treatment decisions.

Abstract
BACKGROUND Anti tumor necrosis factor alpha (TNFα) agents have become widely used in pediatric inflammatory bowel disease (IBD). So far, only few studies examined the long-term results of anti-TNFα treatment in children with IBD. METHODS The long-term outcome of pediatric patients with IBD was assessed retrospectively in a multicenter cohort of children treated with anti-TNFα beyond induction treatment. Short- and long-term response rates, predictors for loss of response, data on growth and laboratory parameters were assessed. RESULTS 120 patients [101 crohn's disease (CD), 19 ulcerative colitis (UC) or indeterminate colitis (IC)] received either infliximab or adalimumab. The mean age at initiation of anti-TNFα was 13.4 ± 3.9 years and the median duration of anti-TNFα treatment was 15 months (range: 2-90). Overall, 89% of the cohort experienced short-term response following induction. Response was associated with improvement in weight and BMI Z-scores (p<0.001) but not with linear growth. Responders experienced a significant decrease in erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) during treatment (p<0.001). Albumin and hemoglobin both improved but only albumin increased significantly (p<0.001). The cumulative probability of losing response to anti-TNFα treatment was 17%, 38%, and 49% after 1, 3, and 5 years, respectively. Responders had a significantly lower weight and BMI Z-scores at initiation of anti-TNFα treatment in compared to non-responders (p=0.04 and 0.02 respectively). CONCLUSIONS Our long term cohort supports the current evidence on the effectiveness and safety of anti-TNFα treatment in children with IBD. Response to treatment was interestingly associated with lower weight and BMI.

Abstract
OBJECTIVES Children with Crohn's disease grow poorly, and inflammation depresses the response of insulin-like growth factor-1 (IGF-1) to growth hormone. Correcting the inflammation normalises growth velocity; however, removing inflammation cannot be achieved in all children. Our lack of understanding of IGF-1 kinetics has hampered its use, particularly as high IGF-1 concentrations over long periods may predispose to colon cancer. We hypothesised that mathematical modelling of IGF-1 would define dosing regimes that return IGF-1 concentrations into the normal range, without reaching values that risk cancer. DESIGN Pharmacokinetic intervention study. SETTING Tertiary paediatric gastroenterology unit. PARTICIPANTS 8 children (M:F; 4:4) entered the study. All completed: 5 South Asian British; 2 White British; 1 African British. INCLUSION CRITERIA Children over 10 years with active Crohn's disease (C reactive protein >10 mg/l or erythrocyte sedimentation rate >25 mm/h) and height velocity <-2 SD score. EXCLUSION CRITERIA closed epiphyses; corticosteroids within 3 months; neoplasia or known hypersensitivity to recombinant human IGF-1 (rhIGF-1). INTERVENTIONS Subcutaneous rhIGF-1 (120 μg/kg) per dose over two admissions: the first as a single dose and the second as twice daily doses over 5 days. PRIMARY OUTCOME Significant increase in circulating IGF-1. SECONDARY OUTCOMES Incidence of side effects of IGF-1. A mathematical model of circulating IGF-1 (Ac) was developed to include parameters of endogenous synthesis (Ksyn); exogenous uptake (Ka) from the subcutaneous dose (As): and IGF-1 clearance: where dAc/dt=Ksyn - Kout×Ac+Ka×As. RESULTS Subcutaneous IGF-1 increased concentrations, which were maintained on twice daily doses. In covariate analysis, disease activity reduced Ksyn (p<0.001). Optimal dosing was derived from least squares regression fitted to a dataset of 384 Crohn's patients, with model parameters assigned by simulation. CONCLUSIONS By using age, weight and disease activity scaling in IGF-1 dosing, over 95% of children will have normalised IGF-1 concentrations below +2.5 SDs of the normal population mean, a level not associated with cancer risk.

Abstract
Growth failure is a typical complication of pediatric inflammatory bowel disease. Factors responsible for stunting are multiple, and proinflammatory cytokines such as TNF-α and IL-6 play a pivotal role. Other determinants are disease severity and location, malnutrition, increased nutritional needs, genetics and drugs. The achievement of optimal linear growth and the remission of gastrointestinal symptoms are the principal targets of pediatric inflammatory bowel disease treatment. Thus, it is very important to assess and monitor linear growth at diagnosis and during follow-up of disease until final adult height achievement. The main strategies for management or prevention of growth impairment in these children are aimed to ensure optimal nutrition, obtain a rapid and complete remission of the disease avoiding or minimizing steroid usage and consider surgical resection, in particular in case of localized ileo or ileocecal disease, to achieve remission in early or mid-puberty. In the last few years, some authors have evaluated the effects of recombinant human growth hormone treatment in children and adolescents with inflammatory bowel disease. However, further studies are needed to better assess its efficacy.

Abstract
OBJECTIVE Treatment of Crohn's disease (CD) with anti-tumor necrosis factor α (TNFα) decreases intestinal inflammation, but the effect on fibrosis remains unclear. We hypothesized that treatment with rat-specific anti-TNFα will decrease the development of intestinal fibrosis in a rat model of CD. We further hypothesized that magnetization transfer magnetic resonance imaging (MT-MRI) will be sensitive in detecting these differences in collagen content. METHODS Rats were injected in the distal ileum and cecum with peptidoglycan-polysaccharide (PG-PS) or human serum albumin (control) at laparotomy and then received intraperitoneal injections of rat-specific anti-TNFα or vehicle daily for 21 days after laparotomy. Rats underwent MT-MRI abdominal imaging on day 19 or 20. MT ratio was calculated in the cecal wall. Cecal tissue histologic inflammation was scored. Cecal tissue procollagen, cytokine, and growth factor messenger RNAs were measured by quantitative real-time PCR. RESULTS PG-PS-injected rats treated with anti-TNFα had less histologic inflammation, and cecal tissue expressed lower levels of proinflammatory cytokine messenger RNAs than vehicle-treated PG-PS-injected rats (IL-1β: 5.59 ± 1.53 versus 10.41 ± 1.78, P = 0.02; IL-6: 23.23 ± 9.33 versus 45.89 ± 11.79, P = 0.07). PG-PS-injected rats treated with anti-TNFα developed less intestinal fibrosis than vehicle-treated PG-PS-injected rats by tissue procollagen I (2.87 ± 0.66 versus 9.28 ± 1.11; P = 0.00002), procollagen III (2.25 ± 0.35 versus 7.28 ± 0.76; P = 0.0000009), and MT-MRI (MT ratio: 17.79 ± 1.61 versus 27.95 ± 1.75; P = 0.0001). Insulin-like growth factor I (2.52 ± 0.44 versus 5.14 ± 0.60; P = 0.0007) and transforming growth factor β1 (2.34 ± 0.29 versus 3.45 ± 0.29; P = 0.006) were also decreased in anti-TNFα-treated PG-PS-injected rats. CONCLUSIONS Anti-TNFα prevents the development of bowel wall inflammation and fibrosis in the PG-PS rat model of CD. MT-MRI measurably demonstrates this decrease in intestinal fibrosis.

Abstract
The traditional goals of Crohn's disease therapy, to induce and maintain clinical remission, have not clearly changed its natural history. In contrast, emerging evidence suggests that achieving and maintaining mucosal healing may alter the natural history of Crohn's disease, as it has been associated with more sustained clinical remission and reduced rates of hospitalization and surgical resection. Induction and maintenance of mucosal healing should therefore be a goal toward which therapy is now directed. Unresolved issues pertain to the benefit of achieving mucosal healing at different stages of the disease, the relationship between mucosal healing and transmural inflammation, the intensity of treatment needed to achieve mucosal healing when it has not been obtained using standard therapy, and the means by which mucosal healing is defined using current endoscopic disease activity indices. The main clinical challenge relates to defining the means of achieving high rates of mucosal healing in clinical practice.
