Abstract
Background Bruceine D (BD) is a major bioactive component isolated from the traditional Chinese medicinal plant Brucea javanica which has been widely utilized to treat dysentery (also known as ulcerative colitis [UC]). Methods To improve the water solubility and absolute bioavailability of BD, we developed a self-nanoemulsifying drug delivery system (SNEDDS) composing of MCT (oil), Solutol HS-15 (surfactant), propylene glycol (co-surfactant) and BD. The physicochemical properties and pharmacokinetics of BD-SNEDDS were characterized, and its anti-UC activity and potential mechanism were evaluated in TNBS-induced UC rat model. Results The prepared nanoemulsion has multiple beneficial aspects including small mean droplet size, low polydispersity index (PDI), high zeta potential (ZP) and excellent stability. Transmission electron microscopy showed that nanoemulsion droplets contained uniform shape and size of globules. Pharmacokinetic studies demonstrated that BD-SNEDDS exhibited enhanced pharmacokinetic parameters as compared with BD-suspension. Moreover, BD-SNEDDS significantly restored the colon length and body weight, reduced disease activity index (DAI) and colon pathology, decreased histological scores, diminished oxidative stress, and suppressed TLR4, MyD88, TRAF6, NF-κB p65 protein expressions in TNBS-induced UC rat model. Conclusion These results demonstrated that BD-SNEDDS exhibited highly improved oral bioavailability and advanced anti-UC efficacy. In conclusion, our current results provided a foundation for further research of BD-SNEDDS as a potential complementary therapeutic agent for UC treatment.

Abstract
Adverse clinical events in primary sclerosing cholangitis (PSC) happen too slowly to capture during clinical trials. Surrogate endpoints are needed, but no such validated endpoints exist for children with PSC. We evaluated the association between gamma glutamyltransferase (GGT) reduction and long-term outcomes in pediatric PSC patients. We evaluated GGT normalization (< 50 IU/L) at 1 year among a multicenter cohort of children with PSC who did or did not receive treatment with ursodeoxycholic acid (UDCA). We compared rates of event-free survival (no portal hypertensive or biliary complications, cholangiocarcinoma, liver transplantation, or liver-related death) at 5 years. Of the 287 children, mean age of 11.4 years old, UDCA was used in 81% at a mean dose of 17 mg/kg/day. Treated and untreated groups had similar GGT at diagnosis (314 versus 300, P= not significant [NS]). The mean GGT was reduced at 1 year in both groups, with lower values seen in treated (versus untreated) patients (99 versus 175, P= 0.002), but 5-year event-free survival was similar (74% versus 77%, P= NS). In patients with GGT normalization (versus no normalization) by 1 year, regardless of UDCA treatment status, 5-year event-free survival was better (91% versus 67%, P< 0.001). Similarly, larger reduction in GGT over 1 year (> 75% versus < 25% reduction) was also associated with improved outcome (5-year event-free survival 88% versus 61%, P= 0.005). Conclusion:A GGT < 50 and/or GGT reduction of > 75% by 1 year after PSC diagnosis predicts favorable 5-year outcomes in children. GGT has promise as a potential surrogate endpoint in future clinical trials for pediatric PSC.

Abstract
Endoscopy is a central tool for the evaluation and management of inflammatory bowel disease (IBD). In the last few decades, gastrointestinal (GI) endoscopy has undergone significant technological developments including availability of pediatric-size equipment, enabling comprehensive investigation of the GI tract in children. Simultaneously, professional organization of GI experts have developed guidelines and training programs in pediatric GI endoscopy. This prompted the Porto Group on Pediatric IBD of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition to develop updated guidelines on the role of GI endoscopy in pediatric IBD, specifically taking into considerations of recent advances in the diagnosis, disease stratification, and novel therapeutic targets in these patients.

Abstract
Anti-tumor necrosis factor (TNF) agents have changed the therapeutic approach to inflammatory bowel disease (IBD). However, a considerable proportion of patients either do not primarily respond or lose response to treatment. Despite the long-standing experience in the use of these drugs, still there is the need of identifying the possible predictors of efficacy. Areas covered: We critically review the current knowledge on predictors of response to anti-TNF therapy - both those available in clinical practice and those still under investigation. Multiple factors are involved in treatment success, including disease phenotype and severity, adherence to medications, and pharmacogenomic, pharmacokinetic, and immunologic factors. Literature search was conducted in PubMed using keywords 'inflammatory bowel disease,' 'Crohn's disease,' and 'ulcerative colitis,' matched with 'antitumor necrosis factor,' 'biologic therapy,' 'clinical response,' 'predictors,' and 'efficacy,' Relevant articles were selected for review. Expert commentary: While the role of several factors in clinical practice is clearly established, other investigational markers have been proposed, mostly in small studies, yet for many of them little external validation exists. Therapeutic drug monitoring is emerging as a pivotal strategy to guide decisions in clinical practice. In the near future, novel markers could improve our ability to direct treatment and personalize therapy.

Abstract
The disease course of children with ulcerative colitis (UC) varies substantially. Published data on predictors of disease outcomes in children remain scarce. We validate clinical predictors of outcomes in 93 children with UC in a single centre (age range: 2-18 years, minimum follow-up: 18 months). We stratified children into 3 groups according to their disease course, that is, 1 = mild (38/93, 40.9%), 2 = moderate (38/93, 40.9%), 3 = severe (17, 18.2%). Comparison of clinical and biochemical parameters was performed between groups using Chi-square, Mann-Whitney, and log-rank tests. Predictors of a severe disease course included pancolitis (P 0.01), low albumin (P 0.005), low haemoglobin at diagnosis (P 0.04), paediatric ulcerative colitis activity index (PUCAI) at 3 months, and nonresponse to steroids at 3 months (P 0.0001). In our cohort, failure to achieve remission at 3 months implied an 80% likelihood to require biologics or major surgery within 18 months. A specific 3-month review point is recommended to guide future management.

Abstract
BACKGROUND The contemporary management of ambulatory ulcerative colitis (UC) continues to be challenging with ∼20% of children needing a colectomy within childhood years. We thus aimed to standardize daily treatment of pediatric UC and inflammatory bowel diseases (IBD)-unclassified through detailed recommendations and practice points. METHODS These guidelines are a joint effort of the European Crohn's and Colitis Organization (ECCO) and the Paediatric IBD Porto group of European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). An extensive literature search with subsequent evidence appraisal using robust methodology was performed before 2 face-to-face meetings. All 40 included recommendations and 86 practice points were endorsed by 43 experts in Paediatric IBD with at least an 88% consensus rate. RESULTS These guidelines discuss how to optimize the use of mesalamine (including topical), systemic and locally active steroids, thiopurines and, for more severe disease, biologics. The use of other emerging therapies and the role of surgery are also covered. Algorithms are provided to aid therapeutic decision-making based on clinical assessment and the Paediatric UC Activity Index (PUCAI). Advice on contemporary therapeutic targets incorporating the use of calprotectin and the role of therapeutic drug monitoring are presented, as well as other management considerations around pouchitis, extraintestinal manifestations, nutrition, growth, psychology, and transition. A brief section on disease classification using the PIBD-classes criteria and IBD-unclassified is also part of these guidelines. CONCLUSIONS These guidelines provide a guide to clinicians managing children with UC and IBD-unclassified management to provide modern management strategies while maintaining vigilance around appropriate outcomes and safety issues.

Abstract
BACKGROUND Diagnosis of pediatric inflammatory bowel diseases (IBD) remains challenging. We aimed at the value of immunohistochemical assessment of CD30+ lymphocytes in the intestinal mucosa in differential diagnosis between pediatric Crohn's disease (CD) and ulcerative colitis (UC) and its utility as a predictor of future differentiation in patients with IBD unclassified (IBDU). METHODS Seventy-four treatment naive pediatric patients with IBD (33 CD, 30 UC and 11 IBDU) were enrolled into the study. Biopsy samples from six different regions (terminal ileum, cecum, ascending colon, transverse colon, descending colon and rectum) were immunohistochemically stained with anti-CD30 antibody, and the number of positive cells per one high power field was quantified. RESULTS Significant differences between CD and UC were found when compared total counts of CD30+ cells in median numbers, mean values and maximal numbers and also for separate counts in terminal ileum, transverse colon, descending colon and rectum. The most profound difference between CD and UC was shown for total median values of CD30+ cells and for the values in rectal localization. The difference was independent on the intensity of inflammation. A cutoff value of 2.5 CD30+ cells with sensitivity 83% and specificity 90% was found for the rectum. There was no difference between patients with CD and IBDU, but a marked difference between UC and IBDU patients was revealed. CONCLUSION Histopathological assessment of biopsy with rectal CD30+ count is reliable and simple method that could help in differential diagnosis among IBD subtypes in children with IBD.

Abstract
BACKGROUND AND AIMS Use of anti-TNF therapies varies internationally. As an initiative of the international Pediatric IBD Network (PIBDNet), we compared global pediatric IBD anti-TNF practice patterns. METHODS Physicians were surveyed about anti-TNF use in Crohn's disease (CD) and ulcerative colitis (UC). Chi-squared, independent samples Mann-Whitney U, or related samples Wilcoxon signed rank tests were used to compare groups. RESULTS 344 physicians treating pediatric IBD responded from 43 countries (54% North America, 29% Europe, 6% Oceania, 6% Asia, 3% Africa, and 2% South America). Respondents treated a median 40 IBD patients. CD was more commonly treated with anti-TNF than UC (40% vs. 10%, p<0.001). North Americans more often used anti-TNF (median 50% vs. 30%, p<0.001) and before immunomodulator (80% vs. 35% CD, p<0.001; 76% vs. 43% steroid-dependent UC, p<0.001). Anti-TNF monotherapy was more common in North America. Anti-TNF in combination with methotrexate, instead of thiopurine, characterized North American practices. North Americans more often continued immunomodulator indefinitely and less often adhered to standard infliximab induction dosing. Access limitations were more common outside North America and Europe for both CD (67% vs. 31%, p<0.001) and UC (62% vs. 33%, p<0.001). CONCLUSIONS Anti-TNF use in North America varies significantly from elsewhere.

Abstract
Background Pediatric ulcerative colitis (UC) presents at an earlier age and increasing prevalence. Our aim was to examine morbidity, steroid sparing strategies, and surgical outcome in children with active UC. Methods A national prospective audit was conducted for the inpatient period of all children with UC for medical or surgical treatment in the United Kingdom (UK) over 1 year. Thirty-two participating centers recruited 224 children in 298 admissions, comparisons over 6 years were made with previous audits. Results Over 6 years, recording of Paediatric Ulcerative Colitis Activity Index (PUCAI) score (median 65)(23% to 55%, P < 0.001), guidelines for acute severe colitis (43% to 77%, P < 0.04), and ileal pouch surgery registration (4% to 56%, P < 0.001) have increased. Corticosteroids were given in 183/298 episodes (61%) with 61/183 (33%) not responding and requiring second line therapy or surgery. Of those treated with anti-TNFalpha (16/61, 26%), 3/16 (18.8%) failed to respond and required colectomy. Prescription of rescue therapy (26% to 49%, P = 0.04) and proportion of anti-TNFalpha (20% to 53%, P = 0.03) had increased, colectomy rate (23.7% to 15%) was not significantly reduced (P = 0.5). Subtotal colectomy was the most common surgery performed (n = 40), and surgical complications from all procedures occurred in 33%. In 215/224 (96%) iron deficiency anemia was detected and in 51% treated, orally (50.2%) or intravenously (49.8%). Conclusions A third of children were not responsive to steroids, and a quarter of these were treated with anti-TNFalpha. Colectomy was required in 41/298 (13.7%) of all admissions. Our national audit program indicates effectiveness of actions taken to reduce steroid dependency, surgery, and iron deficiency. 10.1093/ibd/izy042_video1izy042.video15769503407001.

Abstract
OBJECTIVES Measuring fecal calprotectin (FC) in a laboratory is time-consuming and that is why home tests have been developed. We studied the use of an FC home test in pediatric patients with inflammatory bowel disease (PIBD) in real-life settings. METHODS The patients were asked to perform the IBDoc FC home test monthly for 6 months and to report their clinical disease activity at testing. Clinical decision-making, however, was guided by routine FC enzyme-linked immunosorbent assay (ELISA) for patients with raised IBDoc values. Spare frozen samples were analyzed using ELISA and IBDoc in the laboratory. The participants completed a questionnaire about FC testing at the start and end of the study. RESULTS Of the 52 patients, 35 (67%) ages 5 to 18 years completed the study, and 197 home tests were performed. Of these, 15% failed, mainly because of technical reasons. Just under half of the patients (47%) considered home testing comparable or superior to routine testing. In contrast, the parents were unsatisfied (61%), mostly because the IBDoc results were significantly different from ELISA and they found the phone application difficult to handle but whenever the IBDoc was performed by a laboratory professional it was comparable with ELISA, suggesting that practical issues hampered home testing. Despite their reservations, more than 80% of parents felt that home testing would improve disease management. CONCLUSIONS PIBD patients and their families were interested in FC home monitoring and willing to adopt testing as a part of their disease management, but this approach requires thorough guidance.

Abstract
OBJECTIVES The aims of this retrospective study were to describe ulcerative colitis (UC) phenotype at diagnosis and follow-up and to identify possible predictors of severe disease course. METHODS This was a retrospective, single-center study. We reviewed the charts of patients with UC diagnosed between 2 and 18 years at our referral center from January 2007 to January 2016. Laboratory and clinical features at diagnosis, such as disease extent, atypical phenotypes, extraintestinal manifestations, and therapies, and pattern changes during the follow-up, including relapse rate, disease extension, and the cumulative risk for colectomy were collected. RESULTS One hundred eleven patients were enrolled. Atypical phenotypes were identified at diagnosis in 55 out of 111 patients (49.5%). Extraintestinal manifestations were detected in 16 out of 111 (14.4%) at the diagnosis. During the follow-up 60 out of 111 (54%) patients needed to start azathioprine, 9 out of 111 (8.1%) patients started biologic therapy and 10 out of 111 (patients underwent surgery, resulting in a cumulative risk of 8% at 5 years and 16% at 10 years. Steroid refractoriness (hazard ratio: 13.9) and starting of biologic therapy (hazard ratio: 25.3) represented the best predictors for surgery. The cumulative probability of first relapse was 47% at 6 months and 63% at 1 year. Disease extension was reported in 21 out of 70 patients (30%). CONCLUSION Pediatric UC is associated with a severe phenotype and a high percentage of atypical features. Surgery rate seems to be decreased from early reports.

Abstract
GOALS We conducted a case-control association analysis to establish the role of a common CB2 functional variant, Q63R, in the susceptibility to inflammatory bowel disease (IBD). BACKGROUND Endocannabinoids may limit intestinal inflammation through cannabinoid receptor 1 and/or 2 (CB1, CB2). STUDY We genotyped 217 pediatric IBD patients [112 Crohn's disease (CD), 105 ulcerative colitis (UC)] and 600 controls for the CB2-Q63R variant by Taqman assay. Data were collected from clinical records on age at diagnosis, disease activity, duration and location, extraintestinal manifestations, therapy, clinical relapses, and need for surgery. RESULTS We found a significant association of the CB2-R63 variant with IBD (allele frequencies, P=0.04; genotype distributions, P=0.0006), in particular with CD (allele frequencies, P=0.002; genotype distributions, P=0.00005) and with UC only for genotype distributions (P=0.03). RR carriers showed an increased risk for developing IBD [odds ratio (OR)=1.82; P=0.0002 for IBD; OR=2.02; P=10 for CD; OR=1.63; P=0.02 for UC at 95% confidence interval]. Upon genotype-phenotype evaluation, RR patients showed an increased frequency of moderate-to-severe disease activity at diagnosis in the case of both CD and UC (P=0.01 and P=0.02, respectively) and also an earlier clinical relapse in UC (P=0.04). In UC, all the clinical features related to the CB2 risk allele were still significantly associated with the variant when analyzed using a multivariate logistic regression model (P=0.001). CONCLUSIONS The CB2-Q63R variant contributes to the risk for pediatric IBD, in particular CD. The R63 variant is associated with a more severe phenotype in both UC and CD. Taken together, our data point toward the involvement of the CB2 receptor in the pathogenesis and clinical features of pediatric IBD.

Abstract
Inflammatory bowel disease (IBD) is a chronic nonspecific intestinal inflammatory disease of unknown etiology. This disease includes three main types: Crohn′s disease (CD), ulcerative colitis (UC), and IBD-unclassified (IBD-U). IBD is frequently presented in adults, but in recent years, there is a rising incidence in pediatric populations. Very early onset IBD (VEO-IBD) is a fraction of pediatric IBD, but they have exclusive phenotypic and genetic characteristics such that they are accompanied by severe disease course and resistance to conventional therapy. The purpose of this review is to provide a contemporary overview of the clinical features, pathogenesis, and management of VEO-IBD.

Abstract
PURPOSE OF REVIEW Therapeutic drug monitoring (TDM) has emerged as a useful tool to optimize the use of drug therapies in adults with inflammatory bowel disease (IBD), including both Crohn's disease (CD) and ulcerative colitis (UC), especially during the use of biological therapies, for which the pharmacokinetics and pharmacodynamics are highly variable among patients. Fewer data exist in children. This review examines the current literature on TDM in pediatric IBD. RECENT FINDINGS Drug clearance is affected by a number of patient and disease factors. For thiopurines, adjusting dosing by monitoring 6-thioguanine (6TGN) and 6-methylmercaptopurine ((6MMP) levels is demonstrated to maximize response and minimize toxicity, while monitoring metabolite levels when treating with anti-tumor necrosis factor (anti-TNF) remain controversial. While in adults the use of TDM in the setting of loss of response to anti-TNF therapy is established, in children, only a small number of studies exist, but these too have encouraging results. There are however, conflicting data regarding the optimal timing of TDM, comparing "reactive" monitoring and "proactive" monitoring. No such data exist in pediatrics. TDM is cost-effective, and dose reduction may represent a safety benefit. There are limited adult data for use of TDM for the newer biologics, vedolizumab and ustekinumab, but early results suggest similarly promising utility. The use of TDM in pediatric IBD is increasing in clinical practice, with similar efficacy to adults demonstrated in children with loss of response to anti-TNF therapy. More prospective studies are needed in children to examine proactive monitoring and utility of TDM with newer biologics.

Abstract
BACKGROUND AND AIMS A growing body of evidence supports the need for detailed attention to nutrition and diet in children with inflammatory bowel disease (IBD). We aimed to define the steps in instituting dietary or nutritional management in light of the current evidence and to offer a useful and practical guide to physicians and dieticians involved in the care of pediatric IBD patients. METHODS A group of 20 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to Nutrition Committee of the European Society of Pediatric Gastroenterology, Hepatology and Nutrition Porto, IBD Interest, and Nutrition Committee. A list of 41 predefined questions was addressed by working subgroups based on a systematic review of the literature. RESULTS A total of 53 formal recommendations and 47 practice points were endorsed with a consensus rate of at least 80% on the following topics: nutritional assessment; macronutrients needs; trace elements, minerals, and vitamins; nutrition as a primary therapy of pediatric IBD; probiotics and prebiotics; specific dietary restrictions; and dietary compounds and the risk of IBD. CONCLUSIONS This position paper represents a useful guide to help the clinicians in the management of nutrition issues in children with IBD.

Abstract
Granulocyte/monocyte apheresis (GMA) selectively removes circulating granulocytes and monocytes; important producers of proinflammatory cytokines. Seven children with new-onset inflammatory bowel disease (IBD) colitis were treated with GMA together with mesalazine, and had significant decreases in Pediatric UC Activity Index (P = 0.018) and Mayo endoscopic score (P = 0.013). We investigated the colonic mucosal cytokine profiles (analyzed with real-time polymerase chain reaction), before and after induction treatment, and in 6 non-IBD controls. Significant decreases were seen in Colony Stimulating Factor 2 (P = 0.018), tumor necrosis factor-α (P = 0.028), interleukin (IL)-23α (P = 0.043), IL-1β (P = 0.028), IL-36γ (P = 0.018), IL-10 (P = 0.028), and transforming growth factor beta 1 (P = 0.043) after treatment. In 6 non-IBD controls there were significantly lower levels of IL-12β (P = 0.023) and IL-23α (P = 0.046) compared to the patients with IBD at onset, and IL-22 (P = 0.088) and IL-36γ (P = 0.062) showed lower values without reaching significant differences. We speculate that the decreases in colonic mucosal cytokine profiles after treatment may explain the observed clinical efficacy in the GMA-treated children with IBD.

Abstract
BACKGROUND Vulvar manifestations of inflammatory bowel disease (IBD) are variable in presentation and challenging to treat. We describe vulvar manifestations and treatment response in female adolescents with IBD. CASES We identified 6 patients with vulvar manifestations of IBD and documented treatments using retrospective chart review. Vulvar symptoms occurred without gastrointestinal (GI) symptoms in 1 patient. For the remaining 5 patients, 2 had GI symptoms before the onset of vulvar symptoms (mean time difference, 4.5 years); 3 patients had vulvar symptoms precede the onset of GI symptoms (mean time difference, 3.3 years). Vulvar IBD manifestations included pain, 100% (n = 6); enlargement, "fullness" or "edema" of the labia minora or majora, 66% (n = 4); ulcers, 50% (n = 3); and abscess, 50% (n = 3). Gynecologic procedures included biopsies, incision and drainages, and partial vulvectomies. All patients were treated with multiple systemic therapies. None of the patients responded to surgical or medical treatment alone; all had recalcitrant vulvar symptoms. SUMMARY AND CONCLUSION Vulvar manifestations of IBD might precede GI symptoms in adolescents with IBD. Treatment is challenging and in this series, systemic therapies were the most successful in achieving symptomatic improvement.

Abstract
BACKGROUND AND AIMS Conventional follow-up of teenagers with inflammatory bowel diseases [IBD] is done during scheduled outpatient visits regardless of how well the patient feels. We designed a telemonitoring strategy for early recognition of flares and compared its efficacy with conventional follow-up. METHODS We used a multicentre randomized trial in patients aged 10-19 years with IBD in clinical remission at baseline. Participants assigned to telemonitoring received automated alerts to complete a symptom score and send a stool sample for measurement of calprotectin. This resulted in an individual prediction for flare with associated treatment advice and test interval. In conventional follow-up the health check interval was left to the physician's discretion. The primary endpoint was cumulative incidence of disease flares. Secondary endpoints were percentage of participants with a positive change in quality-of-life and cost-effectiveness of the intervention. RESULTS We included 170 participants [84 telemonitoring; 86 conventional follow-up]. At 52 weeks the mean number of face-to-face visits was significantly lower in the telemonitoring group compared to conventional follow-up [3.6 vs 4.3, p < 0.001]. The incidence of flares [33 vs 34%, p = 0.93] and the proportion of participants reporting positive change in quality-of-life [54 vs 44%, p = 0.27] were similar. Mean annual cost-saving was €89 and increased to €360 in those compliant to the protocol. CONCLUSIONS Telemonitoring is as safe as conventional follow-up, and reduces outpatient visits and societal costs. The positive impact on quality-of-life was similar in the two groups. This strategy is attractive for teenagers and families, and health professionals may be interested in using it to keep teenagers who are well out of hospital and ease pressure on overstretched outpatient services.

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

Abstract
The incidence of pediatric inflammatory bowel disease (IBD) is rising, as is the employment of immunosuppressive and biological drugs. Most patients with IBD receive immunosuppressive therapies during the course of the disease. These molecules are a double-edged sword; while they can help control disease activity, they also increase the risk of infections. Therefore, it is important that pediatricians involved in primary care, pediatric gastroenterologists, and infectious disease physicians have a thorough knowledge of the infections that can affect patients with IBD. Areas covered: A broad review of the major infectious diseases that have been reported in children and adolescents with IBD was performed, and information regarding surveillance, diagnosis and management were updated. The possible correlations with IBD pharmacological tools are discussed. Expert commentary: Opportunistic infections are possible in pediatric IBD, and immunosuppressive and immunomodulator therapy seems to play a causative role. Heightened awareness and vigilant surveillance leading to prompt diagnosis and treatment are important for optimal management.

BACKGROUND Data on the clinical course and outcomes of pediatric patients with cytomegalovirus (CMV) infection complicating acute severe ulcerative colitis (ASC) are very limited. The aim of our study was to compare outcomes of children with ASC who were CMV positive or CMV negative. METHODS This was a multicenter retrospective case-controlled study, from centers affiliated with the Pediatric Inflammatory Bowel Disease Porto Group of European Society of Pediatric Gastroenterology, Hepatology, and Nutrition. We included CMV-positive children hospitalized for ASC and compared their colectomy rate during hospitalization and up to 1 year thereafter, matched with CMV-negative controls. RESULTS A total of 56 children were included; 15 CMV positive and 41 CMV negative. More CMV-positive patients were resistant to intravenous corticosteroids as compared with CMV negative (93% and 56% respectively, P = 0.009). Fourteen of the CMV-positive children (93%) were treated with ganciclovir [5/14 (36%) with 5 mg/kg and 9/14 (64%) with 10 mg/kg]. During hospitalization, 3 (20%) CMV-positive and 3 (7.8%) CMV-negative patients required colectomy (P = 0.17). By 12 months, 5 (33%) and 5 (13%) CMV-positive and CMV-negative patients required colectomy, respectively (P = 0.049); the significance was not retained on multivariate analysis. CONCLUSIONS A higher prevalence of CMVpositivity was found in pediatric ulcerative colitis patients who required colectomy within 12 months of hospitalization for ASC. Further studies are needed to clarify the impact of CMV infection on the outcome of acute severe colitis in pediatric patients.

Abstract
Exclusive enteral nutrition (EEN) is the first line therapy for paediatric Crohn's disease, providing a complete nutritional feed whilst simultaneously inducing remission in up to 80% of cases. The effect of EEN on systemic/local intestinal immune function and subsequent inflammation (including barrier permeability, direct anti-inflammatory effects and cytokine signalling pathways), alongside changes in the microbiome (specific species and broad taxonomic shifts, functional changes) are becoming clearer, however the exact mechanism for induction of remission in Crohn's disease remains uncertain. The evidence of efficacy in paediatric Crohn's disease is strong, with selected adult populations also benefiting from EEN. However despite recommendations from all major societies (ECCO, ESPGHAN, NASPGHAN and ESPEN) first-line use of EEN is varied and Europe/Australasia/Canada show significantly more routine use than other parts of North America. Growth and nutritional status are significantly improved with EEN compared to corticosteroids but long-term outcomes are sparse. This review discusses the evidence underlying the use of EEN, highlighting the mechanisms thought to underlie how EEN induces remission in Crohn's disease, when and how to use EEN, including practical issues in both paediatric and adult practice (formulation, compliance, volumes and administration), and summarises the ongoing research priorities.

Abstract
BACKGROUND AND AIMS The incidence of childhood-onset [< 18 years] inflammatory bowel disease [IBD] is increasing worldwide, and some studies suggest that it represents a more severe disease phenotype. Few nationwide, population-based studies have evaluated the surgical burden in patients with childhood-onset IBD, and whether the improved medical treatment has influenced the need for gastrointestinal surgery. The aim was to examine whether the surgical treatment at any age of patients with childhood-onset IBD has changed over time. METHODS In a nationwide cohort study we identified 4695 children [< 18 years] diagnosed with incident IBD in 2002-2014 through the Swedish Patient Register [ulcerative colitis: n = 2295; Crohn's disease: n = 2174; inflammatory bowel disease-unclassified: n = 226]. Abdominal [intestinal resections and colectomies] and perianal surgeries were identified through the Swedish Patient Register. The cumulative incidences of surgeries were calculated using the Kaplan-Meier method. RESULTS In the cohort, 44% were females and 56% males. The median age at inflammatory bowel disease diagnosis was 15 years and the maximum age at end of follow-up was 31 years. The 3-year cumulative incidence of intestinal surgery was 5% in patients with ulcerative colitis and 7% in patients with Crohn's disease, and lower in children aged < 6 years at inflammatory bowel disease diagnosis [3%] than in those aged 15-17 years at diagnosis [7%]. Calendar period of inflammatory bowel disease diagnosis was not associated with risk of surgery. CONCLUSION Over the past 13 years, the risk of surgery in childhood-onset inflammatory bowel disease has remained unchanged.

Abstract
AIM All Irish children with ulcerative colitis (UC) attend the National Centre for Paediatric Gastroenterology at Our Lady's Children's Hospital, Crumlin. The aim of this study was to determine the outcomes of children with acute severe ulcerative colitis (ASC) and the impact of infliximab on these outcomes following its introduction for this indication in 2011. METHODS A retrospective chart review of all patients admitted with ASC between January 1, 2009 and December 31, 2015 was undertaken. Patients were identified from the departmental database cross-referenced with the hospital inpatient enquiry system. Inpatients with a paediatric ulcerative colitis activity index (PUCAI) of ≥65 were included. Data collected included baseline demographic and laboratory data, concomitant treatments, PUCAI scores on days 3 and 5, second-line treatments, surgery, and discharge outcomes. Infliximab dose, frequency, and available therapeutic drug monitoring results were recorded, along with clinical response outcomes (remission, primary, and secondary loss of response). The cohort was sub-analysed to determine if there was any era effect pre- and post-introduction of infliximab (2009-2010 and 2011-2015, respectively). RESULTS Fifty-five patients (M:F = 1.4:1) were treated for acute severe colitis over the study period (8 in the pre-infliximab and 47 in the post-infliximab era) and 46/55 (86%) had steroid-refractory disease. Of these, 7/8 (88%) required colectomy in the pre-infliximab era, compared with 15/47 (36%) in the post-infliximab era. The remission rate with second-line infliximab was 61% at maximal follow-up. There were no identifiable factors that predicted likely success or failure of infliximab, including gender, CRP, day-3 and day-5 PUCAI scores. Of the 33 patients treated with infliximab, dose increase was required in 23/33 (70%); 21/33 (64%) received an accelerated dose schedule, and 9/33 (27%) eventually needed colectomy. Primary and secondary loss of response to infliximab was seen in one and nine patients, respectively. CONCLUSION This is the first population-based study of the outcomes of severe UC in Irish children, and suggests a higher burden of steroid-refractory disease compared with previous international studies. While infliximab treatment has led to reduction in colectomy rates, a significant proportion of patients lose therapeutic effect.

Abstract
BACKGROUND The concept of an altered collective gut microbiota rather than identification of a single culprit is possibly the most significant development in inflammatory bowel disease research. We have entered the "omics" era, which now allows us to undertake large-scale/high-throughput microbiota analysis which may well define how we approach diagnosis and treatment of inflammatory bowel disease (IBD) in the future, with a strong steer towards personalised therapeutics. AIM To assess current epidemiological, experimental and clinical evidence of the current status of knowledge relating to the gut microbiome, and its role in IBD, with emphasis on reviewing the evidence relating to microbial therapeutics and future microbiome modulating therapeutics. METHODS A Medline search including items 'intestinal microbiota/microbiome', 'inflammatory bowel disease', 'ulcerative colitis', 'Crohn's disease', 'faecal microbial transplantation', 'dietary manipulation' was performed. RESULTS Disease remission and relapse are associated with microbial changes in both mucosal and luminal samples. In particular, a loss of species richness in Crohn's disease has been widely observed. Existing therapeutic approaches broadly fall into 3 categories, namely: accession, reduction or indirect modulation of the microbiome. In terms of microbial therapeutics, faecal microbial transplantation appears to hold the most promise; however, differences in study design/methodology mean it is currently challenging to elegantly translate results into clinical practice. CONCLUSIONS Existing approaches to modulate the gut microbiome are relatively unrefined. Looking forward, the future of microbiome-modulating therapeutics looks bright with several novel strategies/technologies on the horizon. Taken collectively, it is clear that ignoring the microbiome in IBD is not an option.

Abstract
OBJECTIVE The aim of the study was to analyze the effect of granulocyte and monocyte apheresis (GMA) with mesalazine for induction of remission in pediatric patients with newly onset chronic inflammatory bowel disease (IBD) colitis. METHODS Thirteen pediatric patients with newly onset extensive IBD colitis were investigated per the ECCO/ESPGHAN IBD protocol. Of these 13, 12 received 10 treatments with Adacolumn (ADA) during a median of 6.25 weeks in combination with low-to-moderate doses of mesalazine, which was continued after apheresis. A control colonoscopy was performed 12 to 16 weeks after GMA treatment. Primary outcomes were mucosal healing (Mayo endoscopic score) and histopathologic grading of biopsies. A secondary outcome was disease activity as measured by the Pediatric Ulcerative Colitis Activity Index. RESULTS Twelve children (6 girls) with a median age of 14.6 years and a median duration of symptoms at diagnosis of 3.2 months received all planned 10 treatment sessions with ADA. Ten of 12 patients had pancolitis and 2 of 12 extensive colitis. A final diagnosis, however, indicated ulcerative colitis in 10 children and Crohn disease in 2 children. At control colonoscopy, 8 of 12 children were in clinical remission and the Mayo endoscopic score showed significant improvement in 9 of 12 patients (P = 0.006). Complete microscopic remission, according to the Geboes score, was observed in 2 patients. CONCLUSIONS In this small study GMA for induction of remission of newly onset pediatric IBD colitis was effective in 8 of 12 patients. Further controlled studies are warranted to confirm the efficacy of this treatment model.

Abstract
OBJECTIVES The objective of this project was to assess a pediatric institution's use of infliximab and develop and evaluate electronic health record tools to improve safety and efficiency of infliximab ordering through auditing and improved communication.
METHODS Best use of infliximab was defined through a literature review, analysis of baseline use of infliximab at our institution, and distribution and analysis of a national survey. Auditing and order communication were optimized through implementation of mandatory indications in the infliximab orderable and creation of an interactive flowsheet that collects discrete and free-text data. The value of the implemented electronic health record tools was assessed at the conclusion of the project.
RESULTS Baseline analysis determined that 93.8% of orders were dosed appropriately according to the findings of a literature review. After implementation of the flowsheet and indications, the time to perform an audit of use was reduced from 60 minutes to 5 minutes per month. Four months post implementation, data were entered by 60% of the pediatric gastroenterologists at our institution on 15.3% of all encounters for infliximab. Users were surveyed on the value of the tools, with 100% planning to continue using the workflow, and 82% stating the tools frequently improve the efficiency and safety of infliximab prescribing.
CONCLUSIONS Creation of a standard workflow by using an interactive flowsheet has improved auditing ability and facilitated the communication of important order information surrounding infliximab. Providers and pharmacists feel these tools improve the safety and efficiency of infliximab ordering, and auditing data reveal that the tools are being used.

Abstract
The incidence of pediatric-onset ulcerative colitis (UC) is rising. Children often present with a more severe disease phenotype as compared to adults with over a third requiring hospitalization for the management of acute severe ulcerative colitis (ASUC). Further, in pediatric patients presenting with inflammatory bowel disease (IBD) limited to the colon, a definitive diagnosis of UC vs. Crohn's disease is often unclear. Here, we review the unique aspects of pediatric ASUC including the epidemiology, diagnosis, medical, and surgical management of this disease.

Abstract
Inflammatory bowel disease (IBD) is a chronic complex disease of children and adults requiring a range of medications and surgical techniques to induce and maintain remission. In common with other immune-mediated inflammatory disorders, it has shown an ever-increasing rise in incidence worldwide over the last 50 years. The cause of IBD arises from interactions between the microbiome in the gut and the gastrointestinal and systemic immune system in genetically susceptible persons, and with environmental triggers to both develop IBD and have relapses of IBD. The burden of IBD in children and adolescents can be high, and treatment needs a multi-disciplinary approach aiming to abolish symptoms, promote growth and development, and support a restriction-free life. Achieving healing of the intestinal mucosa promotes long-term remission and helps to avoid disease complications.

Abstract
Inflammatory bowel diseases (IBD) are chronic autoimmune conditions of the gut affecting both pediatric and adult patients. Medical therapy is often successful at inducing and maintaining remission and preventing disease complications. The mainstays of treatment are medications and other therapies that reduce inflammation and suppress the overactive immune system. Here we review current medical therapies for pediatric IBD, discuss future therapeutics, and present current treatment goals and approaches.

Abstract
The human gut microbiome exerts a major impact on human health and disease, and therapeutic gut microbiota modulation is now a well-advocated strategy in the management of many diseases, including inflammatory bowel disease (IBD). Scientific and clinical evidence in support of complementary and alternative medicine, in targeting intestinal dysbiosis among patients with IBD, or other disorders, has increased dramatically over the past years. Delivery of "artificial" stool replacements for fecal microbiota transplantation (FMT) could provide an effective, safer alternative to that of human donor stool. Nevertheless, optimum timing of FMT administration in IBD remains unexplored, and future investigations are essential.

Abstract
BACKGROUND Chronic granulomatous disease (CGD) is a primary immunodeficiency of phagocytes, characterized by life-threatening infections and hyperinflammation. Due to survival improvement, inflammatory bowel disease (IBD) is becoming increasingly relevant. Here, we report our 20 year experience. METHODS We retrospectively analyzed clinic, endoscopic, and histologic features, as well as the management of CGD-IBD patients referred to the Bambino Gesù Children's Hospital in Rome, Italy. RESULTS Of 20 patients with CGD, 9 presented with CGD-IBD at diagnosis and/or during follow-up. Symptoms occurred at a median age of 16 years (range 3.2-42), with a median delay of 6 months for endoscopic confirmation. Patients mainly complained of nonspecific diarrhea (55%), with discrepancy between symptom paucity and severe endoscopic appearance, mainly represented by extensive colonic involvement (44%). Histology revealed at least 2 characteristic features (epithelioid granulomas, pigmented macrophages, and increased eosinophils) in 78% of patients. Eight of 9 patients received oral mesalamine, and 5 required systemic steroids. One patient received azathioprine due to steroid dependence. No patient required biological therapy or surgery. Clinical remission was obtained in all patients, but the majority complained of mild relapses. Two episodes of severe infection occurred early after steroid therapy. CONCLUSIONS Penetrance of CGD-IBD increases with age. Clinical manifestations may be subtle, and clinicians should have a low threshold to recommend endoscopy. Treatment with NSAIDs and/or steroids achieves a good response, but relapses usually occur. Infection surveillance is mandatory during treatment, to prevent opportunistic infections. A close collaboration between pediatric immunologists and gastroenterologists is pivotal, including combined follow-up.

Abstract
We describe the case of a pediatric patient on azathioprine therapy with previously undiagnosed homozygote thiopurine S-methyltransferase (TPMT) deficiency, resulting in myelotoxic thiopurine metabolite levels. The patient was successfully treated with a very low azathioprine dose of 50 mg once a week (4% of standard dose), guided by frequent thiopurine metabolite measurement and a close clinical surveillance. We demonstrate that azathioprine therapy still might be an effective and safe therapeutic option in pediatric thiopurine S-methyltransferase-deficient IBD patients.

Abstract
OBJECTIVE There are inconsistent reports on age-related differences in inflammatory bowel disease (IBD). On the basis of patient information, we describe the clinical presentation and therapy in relation to age at diagnosis in longstanding pediatric IBD. PATIENTS AND METHODS Two surveys were conducted in children and young adults (age: 10-25 years) by pretested postal questionnaires. The main analyses are descriptive, showing proportions and distributions per grouped age of diagnosis. Exploratory logistic regression was used to identify sociodemographic and disease-related factors associated with prognosis. Recent disease course, use of biological therapy, and resecting surgery were chosen as indicators of disease severity. Patients with a diagnosis in infancy (<2 years of age) are presented as a case series. RESULTS Information of 1280 cases was available [804 Crohn's disease (CD), 382 ulcerative colitis (UC), 94 IBD not specified] (response: 44.6 and 49.6%). Stable remission during the preceding year was reported by 675 (56.7%) patients; 825 (60.9%) patients reported feeling currenty well. Anti-tumor necrosis factor therapy was reported by 33% of CD patients and 9.3% of UC patients, immunomodulation in 82.1 and 63.2%, and corticosteroids by 78.4 and 76.1%, respectively (ever use). Age at diagnosis was not associated with indicators of severe disease. Diagnosis in infancy was reported by 37 patients. CONCLUSION Our data do not support age at diagnosis-related differences in prognosis in pediatric-onset IBD.

Abstract
To characterize rectal histology in an inception cohort of children newly diagnosed with ulcerative colitis (UC) and to explore its relationship with clinical indices of disease severity. The PROTECT (Predicting Response to Standardized Pediatric Colitis Therapy) Study enrolled children 17 years of age and younger newly diagnosed with UC. Baseline rectal biopsies were evaluated for acute and chronic inflammation, eosinophilic inflammation (peak eosinophil count > 32 eosinophils/high powered field, eosinophilic cryptitis or abscesses), and architectural/nonarchitectural chronic changes. Correlation with clinical indices including Mayo endoscopy subscore and Pediatric Ulcerative Colitis Activity Index was performed. Rectal biopsies from 369 patients (mean age, 12.9±3.1 y, 50% female) were reviewed. Cryptitis was found in 89%, crypt abscesses in 25%, and eosinophilic inflammation in 58%. Crypt distortion/atrophy was present in 98% of specimens. Higher grades of acute and chronic inflammation were associated with the presence of basal plasmacytosis (P<0.0001), basal lymphoid aggregates (P<0.0001), and surface villiform changes (P<0.0001). A severe Mayo endoscopy subscore was most common among those with severe acute and chronic inflammation, although this relationship was not linear. Severe Pediatric Ulcerative Colitis Activity Index scores were associated with the absence of or only mild eosinophilic inflammation (<32 eosinophils/high powered field) (P<0.03) and the presence of surface villiform changes (P<0.005). Acute and chronic inflammation, eosinophilic inflammation and chronic changes are common in children newly diagnosed with UC. The clinical and biological implication of low to absent eosinophilic inflammation and the presence of surface villiform changes requires further study.

Abstract
OBJECTIVES 5-Aminosalicylic acid (5-ASA) is an important maintenance drug for patients with ulcerative colitis. A proportion of the ingested dose is excreted in the urine. Measuring 5-ASA and its metabolites in urine requires mass spectrometry, which is not widely available for this purpose. Urinary 5-ASA can be measured by colorimetry using the serum salicylic acid assay and is a surrogate marker of recent 5-ASA ingestion. We evaluated whether measuring 5-ASA in first morning voids or in random spot urine samples correctly identifies teenagers with poor adherence to oral 5-ASA. METHODS Teenagers who were prescribed a current regimen including >40 mg · kg · day of 5-ASA were invited to collect their spot urine with various time lapses since their last presumed 5-ASA ingestion. Classification of adherence was based on a composite method that included a patient-reported adherence scale and 6-thioguanine levels in erythrocytes. RESULTS Teenagers who were classified as "good adherers" had 66 of 69 (96%; 95% confidence interval 87%-99%) spot urine samples with detectable 5-ASA levels. "Poor adherers" had 30 of 45 (67%; 95% confidence interval 52%-79%) spot urine samples with undetectable 5-ASA levels. The "good adherers" with false-negative urine tests were on a once daily dosing regimen and had collected a spot urine sample shortly before the next dosage. Their first morning voids had detectable 5-ASA levels. CONCLUSIONS Undetectable 5-ASA levels in the first morning void confirms short-term nonadherence to oral 5-ASA.

Abstract
UNLABELLED Low bone mineral density (BMD) and an increased fracture incidence are two extraintestinal complications associated with inflammatory bowel disease (IBD). We aimed to evaluate musculoskeletal traits and assess vertebral fracture (VF) rate in children and adolescents with IBD. Seventy patients with IBD with a median age of 13.8 years were included. The BMD and geometric parameters of the non-dominant tibia were assessed using pQCT. Dynamic muscle functions were evaluated using jumping mechanography. VFs were assessed according to the semiquantitative standardized method by Genant. The muscle functions adjusted for the patients' weight did not differ from the reference population. A low trabecular BMD (Z-score - 1.6; p < 0.001) and cortical thickness (Z-score - 0.7; p < 0.001) were found in children and adolescents with IBD. Conversely, an increased cortical BMD (Z-score 1.1; p < 0.001) was noted. No significant association was found between the 25-OHD serum levels and the bone or muscle measurements. One patient with asymptomatic VF was identified. CONCLUSION IBD in childhood or adolescents affects bones but not muscles. Bone changes are independent of the 25-OHD serum level. A thoracolumbar spine X-ray should not be routinely recommended in children with IBD. What is Known: • Low bone mineral density and an increased fracture rate are the complications associated with IBD. • Bone strength and structural development is strongly dependent on skeletal muscle stimulation. What is New: • Children with IBD have altered bone density and geometry but normal dynamic muscle functions. • Thoracolumbar spine X-ray should be indicated on an individual basis in children with IBD.

Abstract
Objective To assess risk of cancer in patients with childhood onset inflammatory bowel disease in childhood and adulthood.Design Cohort study with matched general population reference individuals using multivariable Cox regression to estimate hazard ratios.Setting Swedish national patient register (both inpatient and non-primary outpatient care) 1964-2014.Participants Incident cases of childhood onset (<18 years) inflammatory bowel disease (n=9405: ulcerative colitis, n=4648; Crohn's disease, n=3768; unclassified, n=989) compared with 92 870 comparators from the general population matched for sex, age, birth year, and county.Main outcome measures Any cancer and cancer types according to the Swedish Cancer Register.Results During follow-up through adulthood (median age at end of follow-up 27 years), 497 (3.3 per 1000 person years) people with childhood onset inflammatory bowel disease had first cancers, compared with 2256 (1.5 per 1000 person years) in the general population comparators (hazard ratio 2.2, 95% confidence interval 2.0 to 2.5). Hazard ratios for any cancer were 2.6 in ulcerative colitis (2.3 to 3.0) and 1.7 in Crohn's disease (1.5 to 2.1). Patients also had an increased risk of cancer before their 18th birthday (2.7, 1.6 to 4.4; 20 cancers in 9405 patients, 0.6 per1000 person years). Gastrointestinal cancers had the highest relative risks, with a hazard ratio of 18.0 (14.4 to 22.7) corresponding to 202 cancers in patients with inflammatory bowel disease. The increased risk of cancer (before 25th birthday) was similar over time (1964-1989: 1.6, 1.0 to 2.4; 1990-2001: 2.3, 1.5 to 3.3); 2002-06: 2.9, 1.9 to 4.2; 2007-14: 2.2, 1.1 to 4.2).Conclusion Childhood onset inflammatory bowel disease is associated with an increased risk of any cancer, especially gastrointestinal cancers, both in childhood and later in life. The higher risk of cancer has not fallen over time.

Abstract
BACKGROUND To individualize timing of infliximab (IFX) treatment in children and adolescents with inflammatory bowel disease (IBD) using a patient-managed eHealth program. METHODS Patients with IBD, 10 to 17 years old, treated with IFX were prospectively included. Starting 4 weeks after their last infusion, patients reported a weekly symptom score and provided a stool sample for fecal calprotectin analysis. Based on symptom scores and fecal calprotectin results, the eHealth program calculated a total inflammation burden score that determined the timing of the next IFX infusion (4-12 wk after the previous infusion). Quality of Life was scored by IMPACT III. A control group was included to compare trough levels of IFX antibodies and concentrations and treatment intervals. Patients and their parents evaluated the eHealth program. RESULTS There were 29 patients with IBD in the eHealth group and 21 patients with IBD in the control group. During the control period, 94 infusions were provided in the eHealth group (mean interval 9.5 wk; SD 2.3) versus 105 infusions in the control group (mean interval 6.9 wk; SD 1.4). Treatment intervals were longer in the eHealth group (P < 0.001). Quality of Life did not change during the study. Appearance of IFX antibodies did not differ between the 2 groups. Eighty percent of patients reported increased disease control and 63% (86% of parents) reported an improved knowledge of the disease. CONCLUSIONS Self-managed, eHealth-individualized timing of IFX treatments, with treatment intervals of 4 to 12 weeks, was accompanied by no significant development of IFX antibodies. Patients reported better control and improved knowledge of their IBD.

Abstract
INTRODUCTION Ulcerative colitis (UC) is a chronic, relapsing condition characterised by colonic inflammation. Increasing prevalence in early-age diagnosis provides opportunities for additional complications in later life as a result of prolonged exposure to inflammatory and therapeutic insults, necessitating novel avenues for therapeutics which may result in fewer side effects. Faecal microbiota transplantation (FMT) has previously demonstrated potential therapeutic benefit in an adult randomised-controlled trial and several recurrent Clostridium difficile infection studies. This phase Ib pilot will be the first randomised, single-blinded, placebo-controlled trial to assess feasibility and patient outcomes in a paediatric inflammatory bowel disease (IBD) population. METHODS AND ANALYSIS Fifty patients will be randomised 1:1 to receive normal saline control or active sample. Enema administrations will be performed two times per week for 6 weeks, followed at a 6-month follow-up period. Feasibility outcomes will include measures of patient eligibility, recruitment, willingness to participate, samples collections, hospitalizations and drop-out rate. Improvements in disease symptoms will determine the efficacy of treatment. Clinical disease scores will be taken throughout the study period using the Paediatric Ulcerative Colitis Activity Index (PUCAI). Monitoring of inflammatory markers in blood and stool will be performed at regular intervals. Microbiome analysis will be conducted on stool samples collected throughout the trials period. Imaging and endoscopic surveillance will be conducted if clinically necessary. ETHICS AND DISSEMINATION Ethics was obtained from local hospital research ethics boards across all three sites. Health Canada and FDA approval was obtained for the use of an Investigatory New Drug product. Results from this trial will be presented in international conferences and published in peer-review journals. TRIAL REGISTRATION NUMBER Trial registration number: NCT02487238; preresults.

Abstract
Patients with inflammatory bowel diseases (IBD) require life-long medications, which even if effective have the potential to cause adverse effects as additional morbidity factors. In pediatric patients, drug therapy has more serious limitations, including impaired physical and mental development. A non-drug therapeutic option is believed to be depletion of elevated and activated granulocytes and monocytes known to release inflammatory cytokines, like the CD14+CD16+ monocyte phenotype known to release tumor necrosis factor-α. Areas covered: Granulomonocyteapheresis (GMA) with an Adacolumn as a treatment option for IBD patients has been applied for the past 15 years. This article reviews the argument that GMA is a relevant and effective non-pharmacologic intervention in pediatric IBD setting. Expert commentary: GMA with an Adacolumn has shown promise in adult, pediatric, and adolescent patients with active IBD. There is evidence of post-GMA immunomodulation in terms of increased regulatory T-cell and B-cell activities. Additionally, patients who respond to GMA may attain a favorable long-term clinical course by avoiding pharmacologicals during an early phase of their active IBD. GMA has a good safety profile, especially in difficult-to-treat and pediatric settings. An additional trial is warranted to assess the efficacy of GMA in the early phase of pediatric IBD to optimize patient selection.

Abstract
INTRODUCTION Intestinal complications in inflammatory bowel disease indicate active inflammation and typically result in the intensification of therapy. AIM To analyse whether the rates of intestinal complications were associated with age at disease onset. PATIENTS AND METHODS Data from 1506 individuals with Crohn's disease (CD) and 1201 individuals with ulcerative colitis (UC) were obtained from the Swiss inflammatory bowel disease cohort study database, classified into groups on the basis of age at diagnosis (<10, <17, <40 and >40 years of age), and retrospectively analysed. RESULTS In CD patients, the rates of stricturing (29.1-36.2%), abdominal penetrating disease (11.9-18.2%), resectional surgery (17.9-29.8%) and perianal disease (14.7-34.0%) were correlated with disease duration, but not age at diagnosis. However, paediatric-onset CD was associated with higher rates of multiple, rectal and anal strictures and earlier colon surgery. In addition, perianal disease occurred earlier, required earlier surgical intervention, and was more often combined with stricturing and penetrating disease. Finally, anal fissures were more prevalent among younger patients. In UC patients, the rates of progression or extension of disease (0-25.8%) and colectomy (3.0-8.7%) were dependent on disease duration, but not age at disease onset. Paediatric-onset disease was associated with a higher rate of extensive colitis at diagnosis and earlier progression or extension of disease, and nonsurgically treated patients with the youngest ages at onset more frequently required antitumour necrosis factor-α treatments. CONCLUSION The higher rates of intestinal complications, including those of the small and large bowel and in the anal region, in paediatric-onset CD patients point towards a level of inflammation that is more difficult to control. Similar findings were also evident in UC patients.

BACKGROUND Paediatric ulcerative colitis [UC] is more extensive than adult disease, and more often refractory to mesalamine. However, no prospective trials have evaluated mesalamine enemas for inducing remission in children. Our goal was to evaluate the ability of mesalamine enemas to induce remission in mild to moderate paediatric UC refractory to oral mesalamine. METHODS This was an open-label arm of a previously reported randomised controlled trial of once-daily mesalamine in active paediatric UC [MUPPIT trial]. Children aged 4-18 years, with a Paediatric Ulcerative Colitis Activity Index [PUCAI] score of 10-55, were enrolled after failing at least 3 weeks of full-dose oral mesalamine. Patients treated with steroids or enemas in the previous month and those with isolated proctitis were excluded. Children received Pentasa® enemas 25 mg/kg [up to 1g] daily for 3 weeks with the previous oral dose. The primary endpoint was clinical remission by Week 3. RESULTS A total of 38 children were enrolled (mean age 14.6 ± 2.3 years; 17/38 [45%] with extensive colitis). Clinical remission was obtained in 16 [42%] and response was obtained in 27 [71%] at Week 3. Eight children deteriorated and required steroids. There were no differences in baseline parameters between those who entered or failed to enter remission, including disease extent [43% in left-sided and 41% in extensive colitis] and disease activity [44% in mild and 41% in moderate activity]. CONCLUSION Clinical remission can be markedly increased in children who are refractory to oral mesalamaine by adding mesalamine enemas for 3 weeks, before commencing steroids.

Abstract
UNLABELLED There are limited data on the natural history of primary sclerosing cholangitis (PSC) in children. We aimed to describe the disease characteristics and long-term outcomes of pediatric PSC. We retrospectively collected all pediatric PSC cases from 36 participating institutions and conducted a survival analysis from the date of PSC diagnosis to dates of diagnosis of portal hypertensive or biliary complications, cholangiocarcinoma, liver transplantation, or death. We analyzed patients grouped by disease phenotype and laboratory studies at diagnosis to identify objective predictors of long-term outcome. We identified 781 patients, median age 12 years, with 4,277 person-years of follow-up; 33% with autoimmune hepatitis, 76% with inflammatory bowel disease, and 13% with small duct PSC. Portal hypertensive and biliary complications developed in 38% and 25%, respectively, after 10 years of disease. Once these complications developed, median survival with native liver was 2.8 and 3.5 years, respectively. Cholangiocarcinoma occurred in 1%. Overall event-free survival was 70% at 5 years and 53% at 10 years. Patient groups with the most elevated total bilirubin, gamma-glutamyltransferase, and aspartate aminotransferase-to-platelet ratio index at diagnosis had the worst outcomes. In multivariate analysis PSC-inflammatory bowel disease and small duct phenotypes were associated with favorable prognosis (hazard ratios 0.6, 95% confidence interval 0.5-0.9, and 0.7, 95% confidence interval 0.5-0.96, respectively). Age, gender, and autoimmune hepatitis overlap did not impact long-term outcome. CONCLUSION PSC has a chronic, progressive course in children, and nearly half of patients develop an adverse liver outcome after 10 years of disease; elevations in bilirubin, gamma-glutamyltransferase, and aspartate aminotransferase-to-platelet ratio index at diagnosis can identify patients at highest risk; small duct PSC and PSC-inflammatory bowel disease are more favorable disease phenotypes.
