High Body Mass Index and Response to Anti-Tumor Necrosis Factor Therapy in Pediatric Crohn's Disease.

INTRODUCTION: Obesity is common among patients with pediatric Crohn's disease (PCD). Some adult studies suggest obese patients respond less well to anti-tumor necrosis factor (TNF) treatment. This study sought compares anti-TNF response and anti-TNF levels between pediatric patients with normal and high body mass index (BMI). METHODS: The COMBINE trial compared anti-TNF monotherapy with combination therapy with methotrexate in patients with PCD. In this secondary analysis, a comparison of time-to-treatment failure among patients with normal BMI vs BMI Z -score >1, adjusting for prescribed anti-TNF (infliximab [IFX] or adalimumab [ADA]), trial treatment assignment (combination vs monotherapy), and relevant covariates. Median anti-TNF levels across BMI category was also examined. RESULTS: Of 224 participants (162 IFX initiators and 62 ADA initiators), 111 (81%) had a normal BMI and 43 (19%) had a high BMI. High BMI was associated with treatment failure among ADA initiators (7/10 [70%] vs 12/52 [23%], hazard ratio 0.29, P = 0.007) but not IFX initiators. In addition, ADA-treated patients with a high BMI had lower ADA levels compared with those with normal BMI (median 5.8 vs 12.8 µg/mL, P = 0.02). IFX trough levels did not differ between BMI groups. DISCUSSION: Overweight and obese patients with PCD are more likely to experience ADA treatment failure than those with normal BMI. Higher BMI was associated with lower drug trough levels. Standard ADA dosing may be insufficient for overweight children with PCD. Among IFX initiators, there was no observed difference in clinical outcomes or drug levels, perhaps due to weight-based dosing and/or greater use of proactive drug monitoring.

Variability of Psychosocial Services Within the ImproveCareNow Learning Health System: Opportunities for Optimization.

Care for youth with pediatric inflammatory bowel disease (IBD) is the focus of ImproveCareNow (ICN), an international learning health system devoted to quality care and improved outcomes through collaboration, data sharing, and research. Known to be significantly disruptive to normative social development and quality of life, pediatric IBD significantly increases the risk of internalizing distress and secondary developmental sequelae. While multidisciplinary support including psychosocial care (from social workers and pediatric psychologists) is growing, this evidence-based and beneficial set of services is not universally available to youth with IBD. In a survey sent to the more than 100 established ICN centers, psychosocial providers attempted to identify the coverage and practice scope of psychosocial providers within the network. Results indicated that support varies widely by service type and availability of providers. Recommendations for further research and considerations for centers seeking to expand supports are considered.

Personalized Research on Diet in Ulcerative Colitis and Crohn's Disease: A Series of N-of-1 Diet Trials.

INTRODUCTION: Evidence about specific carbohydrate diet (SCD) for inflammatory bowel disease (IBD) is limited. We conducted 54 single-subject, double-crossover N-of-1 trials comparing SCD with a modified SCD (MSCD) and comparing each with the participant's baseline, usual diet (UD). METHODS: Across 19 sites, we recruited patients aged 7-18 years with IBD and active inflammation. Following a 2-week baseline (UD), patients were randomized to 1 of 2 sequences of 4 alternating 8-week SCD and MSCD periods. Outcomes included fecal calprotectin and patient-reported symptoms. We report posterior probabilities from Bayesian models comparing diets. RESULTS: Twenty-one (39%) participants completed the trial, 9 (17%) completed a single crossover, and 24 (44%) withdrew. Withdrawal or early completion occurred commonly (lack of response [n = 11], adverse events [n = 11], and not desiring to continue [n = 6]). SCD and MSCD performed similarly for most individuals. On average, there was <1% probability of a clinically meaningful difference in IBD symptoms between SCD and MSCD. The average treatment difference was -0.3 (95% credible interval -1.2, 0.75). There was no significant difference in the ratio of fecal calprotectin geometric means comparing SCD and MSCD (0.77, 95% credible interval 0.51, 1.10). Some individuals had improvement in symptoms and fecal calprotectin compared with their UD, whereas others did not. DISCUSSION: SCD and MSCD did not consistently improve symptoms or inflammation, although some individuals may have benefited. However, there are inherent difficulties in examining dietary changes that complicate study design and ultimately conclusions regarding effectiveness.

Whole-genome sequencing of African Americans implicates differential genetic architecture in inflammatory bowel disease.

Whether or not populations diverge with respect to the genetic contribution to risk of specific complex diseases is relevant to understanding the evolution of susceptibility and origins of health disparities. Here, we describe a large-scale whole-genome sequencing study of inflammatory bowel disease encompassing 1,774 affected individuals and 1,644 healthy control Americans with African ancestry (African Americans). Although no new loci for inflammatory bowel disease are discovered at genome-wide significance levels, we identify numerous instances of differential effect sizes in combination with divergent allele frequencies. For example, the major effect at PTGER4 fine maps to a single credible interval of 22 SNPs corresponding to one of four independent associations at the locus in European ancestry individuals but with an elevated odds ratio for Crohn disease in African Americans. A rare variant aggregate analysis implicates Ca2+-binding neuro-immunomodulator CALB2 in ulcerative colitis. Highly significant overall overlap of common variant risk for inflammatory bowel disease susceptibility between individuals with African and European ancestries was observed, with 41 of 241 previously known lead variants replicated and overall correlations in effect sizes of 0.68 for combined inflammatory bowel disease. Nevertheless, subtle differences influence the performance of polygenic risk scores, and we show that ancestry-appropriate weights significantly improve polygenic prediction in the highest percentiles of risk. The median amount of variance explained per locus remains the same in African and European cohorts, providing evidence for compensation of effect sizes as allele frequencies diverge, as expected under a highly polygenic model of disease.

Development and Testing of a New Simplified Endoscopic Mucosal Assessment for Crohn's Disease: The SEMA-CD.

OBJECTIVES: Endoscopic mucosal improvement is the gold standard for assessing treatment efficacy in clinical trials of Crohn's disease. Current endoscopic indices are not routinely used in clinical practice. The lack of endoscopic information in large clinical registries limits their use for research. A quick, easy, and accurate method is needed for assessing mucosal improvement for clinicians in real-world practice. We developed and tested a novel simplified endoscopic mucosal assessment for Crohn's disease (SEMA-CD). METHODS: We developed a 5-point scale for ranking endoscopic severity of ileum and colon based on Simple Endoscopic Score for Crohn's disease (SES-CD). Central readers were trained to perform SES-CD and SEMA-CD. Pediatric patients with Crohn's disease undergoing colonoscopy were enrolled. Video recordings of colonoscopies were de-identified and randomly assigned to blinded central readers. The SES-CD and SEMA-CD were scored for each video. The SES-CD was considered the validated standard for comparison. Correlation was assessed with Spearman rho, inter- and intrarater reliability with kappa statistics. RESULTS: Fifty-seven colonoscopies were read a total of 212 times. Correlation between SEMA-CD and SES-CD was strong (rho = 0.98, P < 0.0001). Inter-rater reliability for SEMA-CD was 0.80, and intrarater reliability was 0.83. Central readers rated SEMA-CD as easier than SES-CD. CONCLUSION: The SEMA-CD accurately and reproducibly correlates with the standard SES-CD. Central readers viewed SEMA-CD as easier than SES-CD. Use of SEMA-CD in practice should enable collecting mucosal improvement information in large populations of patients. This will improve the quality of research that can be conducted in clinical registries. External validation is needed.

Transition to Adult IBD Care: A Pilot Multi-Site, Telehealth Hybrid Intervention.

OBJECTIVE: Transition to adult IBD care continues to be a challenge. Efficacious models of improving transition to adult care in the United States are lacking. We present data from a pilot, prospective, non-randomized, intervention implemented at IBD centers in the Midwest and Southeast United States. DESIGN AND METHODS: Adolescents and young adults (AYAs; 16-20 years) with IBD and their parents completed a 4- to 5-month transition program (1 in-person group session; 4 individual telehealth sessions). Primary outcomes were feasibility (i.e., recruitment, retention, fidelity) and acceptability (i.e., program satisfaction). Secondary outcomes were changes in transition readiness, self-management skill acquisition, perceived readiness to transfer to adult care, and disease knowledge. RESULTS: The study exceeded goals for recruitment (target N = 20; actual: 36) and retention (target: 80%; actual: 86.11%). On average, it took participants 20.91 ± 3.15 weeks to complete our 4- to 5-month intervention and there were no deviations from the study protocol. Participant ratings for overall program satisfaction, perceived helpfulness, and program length and format were positive. Increases in transition readiness, t(30) = 8.30, d = 1.49, p < .001, self-management skill acquisition, t(30) = 3.93, d = 0.70, p < .001, and disease knowledge, t(30) = 8.20, d = 1.58, p < .001 were noted. AYA- and parent-perceived transfer readiness also improved (p's < .05; d's = 0.76-1.68). CONCLUSIONS: This article presents feasibility and acceptability data for a 4- to 5-month transition intervention. Improvements in AYA transition readiness, self-management skill acquisition, IBD knowledge, and AYA/parent perceived transfer readiness were also observed.

Technology-Enabled Health Care Collaboration in Pediatric Chronic Illness: Pre-Post Interventional Study for Feasibility, Acceptability, and Clinical Impact of an Electronic Health Record-Linked Platform for Patient-Clinician Partnership.

BACKGROUND: Mobile health (mHealth) technology has the potential to support the Chronic Care Model's vision of closed feedback loops and patient-clinician partnerships. OBJECTIVE: This study aims to evaluate the feasibility, acceptability, and short-term impact of an electronic health record-linked mHealth platform (Orchestra) supporting patient and clinician collaboration through real-time, bidirectional data sharing. METHODS: We conducted a 6-month prospective, pre-post, proof-of-concept study of Orchestra among patients and parents in the Cincinnati Children's Hospital inflammatory bowel disease (IBD) and cystic fibrosis (CF) clinics. Participants and clinicians used Orchestra during and between visits to complete and view patient-reported outcome (PRO) measures and previsit plans. Surveys completed at baseline and at 3- and 6-month follow-up visits plus data from the platform were used to assess outcomes including PRO completion rates, weekly platform use, disease self-efficacy, and impact on care. Analyses included descriptive statistics; pre-post comparisons; Pearson correlations; and, if applicable, effect sizes. RESULTS: We enrolled 92 participants (CF: n=52 and IBD: n=40), and 73% (67/92) completed the study. Average PRO completion was 61%, and average weekly platform use was 80%. Participants reported improvement in self-efficacy from baseline to 6 months (7.90 to 8.44; P=.006). At 6 months, most participants reported that the platform was useful (36/40, 90%) and had a positive impact on their care, including improved visit quality (33/40, 83%), visit collaboration (35/40, 88%), and visit preparation (31/40, 78%). PRO completion was positively associated with multiple indicators of care impact at 3 and 6 months. CONCLUSIONS: Use of an mHealth tool to support closed feedback loops through real-time data sharing and patient-clinician collaboration is feasible and shows indications of acceptability and promise as a strategy for improving pediatric chronic illness management.

Acute pancreatitis in children: Updates in epidemiology, diagnosis and management.

Acute pancreatitis (AP), manifesting as acute onset of abdominal pain, vomiting, and nausea, is increasingly being recognized in children secondary to increased awareness, more identifiable etiologies as well as advances in diagnostic capabilities, like imaging. Despite this increased awareness and ability for more frequent diagnoses, the natural history of AP remains poorly understood leading to gaps in approach and management, especially in children. Coupled with poor epidemiologic and management awareness, there remains a lack of understanding of the long term implications of severe acute pancreatitis (SAP). Hence, the role of the primary care clinician in the early diagnosis, and management, remains critical and may affect the need for consultation with pediatric sub-specialists like gastroenterologists. This review provides guidelines regarding epidemiology, diagnosis, and management strategies to address some of these gaps.

Improving IBD Transition, Self-management, and Disease Outcomes With an In-clinic Transition Coordinator.

OBJECTIVES: Deficits in the preparation of patients with inflammatory bowel disease (IBD) who are transitioning to adult care are known yet studies presenting outcome data of transition interventions in IBD are lacking. We present data evaluating the impact of a transition coordinator on behavioral and clinical transition outcomes. METHODS: A retrospective chart review identified 135 patients who had met with our transition coordinator and completed the Transition Readiness Assessment Questionnaire before, and 1 year after, the intervention. Changes in transition readiness, self-management skill acquisition, and clinical outcomes (eg, number of patients transferred vs "bounced back" to pediatrics, percentage of patients over age 21, changes in disease remission) were examined and compared with patients who received no intervention. RESULTS: Intervention participants demonstrated a significant increase in transition readiness, F(1, 134) = 24.34, P < 0.001, and self-management skill acquisition, F(1, 134) = 5.61, P < 0.05. The percentage of patients in remission significantly increased from pre- to post-intervention, χ(134) = 9.03, P < 0.01. There were no significant changes in the comparison population (Ps > 0.05). Following implementation of our programming, the percentage of patients over age 21 decreased by 33.07%. CONCLUSIONS: A 1-time transition coordinator-led intervention improved adolescent transition readiness and acquisition of self-management skills. The proportion of young adult patients retained in pediatric care was reduced. Benefits of hiring a transition coordinator are discussed.

Multi-Site Comparison of Patient, Parent, and Pediatric Provider Perspectives on Transition to Adult Care in IBD.

PURPOSE: This multi-site study examines patient, parent, and pediatric provider perspectives on what is most important for successful transition. DESIGN AND METHODS: Using the Transition Readiness Assessment Questionnaire, 190 participants recruited from two pediatric IBD centers selected the top five skills they considered "most important for successful transition." Rankings were summarized and compared by group. RESULTS: While patients, parents, and clinicians all identified "calling the doctor about unusual changes in health" and "taking medications correctly and independently" as being important, each stakeholder group qualitatively and statistically differed in terms of transition readiness skills emphasized. Patients endorsed "calling the doctor about unusual changes in health" and "being knowledgeable about insurance coverage," as being most important to successful transition while parents emphasized health monitoring and problem solving. Pediatric providers emphasized adherence to treatment and reporting unusual changes in health. There were statistically significant differences in endorsement rates across participants for seven transition readiness skills. Patients agreed with providers 80% of the time and with their parents 40% of the time. Parent-provider agreement was 60%. CONCLUSIONS: Although there was some overlap across groups, areas of emphasis differed by informant. Patients emphasized skills they need to learn, parents emphasized skills they most likely manage for their children, and providers emphasized skills that directly impact their provision of care. PRACTICE IMPLICATIONS: Patient, parent, and provider beliefs all need to be considered when developing a comprehensive transition program. Failure to do so may result in programs that do not meet the needs of youth with IBD.

Biologics Delay Progression of Crohn's Disease, but Not Early Surgery, in Children.

BACKGROUND & AIMS: Up to 30% of patients with Crohn's disease (CD) require surgery within the first 5 years from diagnosis. We investigated the recent risk of bowel surgery in an inception cohort of pediatric patients with CD and whether early use of biologics (tumor necrosis factor antagonists) alters later disease course. METHODS: We collected data from the Pediatric Inflammatory Bowel Disease Collaborative Research Group registry on 1442 children (age, ≤16 y) diagnosed with CD from January 2002 through December 2014. Data were collected at diagnosis, 30 days following diagnosis, and then quarterly and during hospitalizations for up to 12 years. Our primary aim was to determine the 10-year risk for surgery in children with CD. Our secondary aim was to determine whether early use of biologics (<3 mo of diagnosis) affected risk of disease progression. RESULTS: The 10-year risk of first bowel surgery was 26%. The 5-year risk of bowel surgery did not change from 2002 through 2014, and remained between 13% and 14%. Most surgeries occurred within 3 years from diagnosis. The only predictor of surgery was disease behavior at diagnosis. CD with inflammatory behavior had the lowest risk of surgery compared to stricturing disease, penetrating disease, or both. We associated slowing of disease progression to stricturing or penetrating disease (but not surgery) with early use of biologics, but this effect only became evident after 5 years of disease. Our results indicate that biologics slow disease progression over time (hazard ratio, 0.85; 95% CI, 0.76-0.95). CONCLUSIONS: In an analysis of data from a registry of pediatric patients with CD, we found that among those with significant and progressing disease at or shortly after presentation, early surgery is difficult to prevent, even with early use of biologics. Early use of biologics (<3 mo of diagnosis) can delay later disease progression to stricturing and/or penetrating disease, but this affect could become evident only years after initial management decisions are made.

Perceived medication adherence barriers mediating effects between gastrointestinal symptoms and health-related quality of life in pediatric inflammatory bowel disease.

OBJECTIVES: The primary objective was to investigate the mediating effects of patient-perceived medication adherence barriers in the relationship between gastrointestinal symptoms and generic health-related quality of life (HRQOL) in adolescents with inflammatory bowel disease (IBD). The secondary objective explored patient health communication and gastrointestinal worry as additional mediators with medication adherence barriers in a serial multiple mediator model. METHODS: The Pediatric Quality of Life Inventory™ Gastrointestinal Symptoms, Medicines, Communication, Gastrointestinal Worry, and Generic Core Scales were completed in a 9-site study by 172 adolescents with IBD. Gastrointestinal Symptoms Scales measuring stomach pain, constipation, or diarrhea and perceived medication adherence barriers were tested for bivariate and multivariate linear associations with HRQOL. Mediational analyses were conducted to test the hypothesized mediating effects of perceived medication adherence barriers as an intervening variable between gastrointestinal symptoms and HRQOL. RESULTS: The predictive effects of gastrointestinal symptoms on HRQOL were mediated in part by perceived medication adherence barriers. Patient health communication was a significant additional mediator. In predictive analytics models utilizing multiple regression analyses, demographic variables, gastrointestinal symptoms (stomach pain, constipation, or diarrhea), and perceived medication adherence barriers significantly accounted for 45, 38, and 29 percent of the variance in HRQOL (all Ps < 0.001), respectively, demonstrating large effect sizes. CONCLUSIONS: Perceived medication adherence barriers explain in part the effects of gastrointestinal symptoms on HRQOL in adolescents with IBD. Patient health communication to healthcare providers and significant others further explain the mechanism in the relationship between gastrointestinal symptoms, perceived medication adherence barriers, and HRQOL.

The Role of Combination Therapy in Pediatric Inflammatory Bowel Disease: A Clinical Report from the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

The treatment goal for children suffering from inflammatory bowel disease has been evolving with biologic therapies like anti-tumor necrosis factor agents assuming a more central role in treatment of more aggressive and extensive phenotype. Earlier introduction of anti-tumor necrosis factor agents have shown to be more effective and may even alter the natural history of inflammatory bowel disease. Development of anti-drug antibodies, however, limits long-term usage and leads to dose adjustment in almost half of patients treated with these medications. One of the strategies to minimize the development of anti-drug antibodies has been concomitant use of immunomodulator medications, resulting in fewer infusion reactions and sustained trough levels, potentially lowering the need for dose adjustments. Balanced with these benefits of optimized dosing and likely more sustained response, however, is the concern about increased risk of complications, such as infections and malignancies. The current manuscript reviews the available pediatric literature regarding efficacy, safety, and side effect profile of combination (immunomodulator and biologics) therapy in pediatric Crohn disease and ulcerative colitis, with particular emphasis on cost constraints, and recommendations for selection of patients who would benefit most from combination therapy.

Magnetic Resonance Enterography Cannot Replace Upper Endoscopy in Pediatric Crohn Disease: An Imagekids Sub-study.

OBJECTIVES: Although magnetic resonance enterography (MRE) can accurately reflect ileal inflammation in pediatric Crohn disease (CD), there are no pediatric data on the accuracy of MRE to detect upper gastrointestinal tract (UGI) lesions. We aimed to compare MRE and esophagogastroduodenoscopy (EGD) in detecting the spectrum and severity of UGI disease in children. METHODS: This is an ancillary study of the prospective multi-center ImageKids study focusing on pediatric MRE. EGD was performed within 2 weeks of MRE (at disease onset or thereafter) and explicitly scored by SES-CD modified for the UGI and physician global assessment. Local and central radiologists scored the UGI region of the MRE blinded to the EGD. Accuracy of MRE compared with EGD was examined using correlational coefficients (r) and area under receiver operating characteristic curves (AUC). RESULTS: One hundred and eighty-eight patients were reviewed (mean age 14 ±â€Š1 years, 103 [55%] boys); 66 of 188 (35%) children had macroscopic ulcerations on EGD (esophagus, 13 [7%]; stomach, 34 [18%]; duodenum, 45 [24%]). Most children had aphthous ulcers, but 10 (5%) had larger ulcers (stomach, 2 [1%]; duodenum, 8 [4%]). There was no agreement between local and central radiologists on the presence or absence of UGI inflammation on MRE (Kappa = -0.02, P = 0.71). EGD findings were not accurately detected by MRE, read locally or centrally (r = -0.03 to 0.11, P = 0.18-0.88; AUC = 0.47-0.55, P = 0.53-1.00).No fistulae or narrowings were identified on either EGD or MRE. CONCLUSIONS: MRE cannot reliably assess the UGI in pediatric CD and cannot replace EGD for this purpose.

Improving health maintenance supervision in a paediatric IBD clinic.

BACKGROUND: Previsit planning (PVP) has been an integral part of clinical care for paediatric patients with inflammatory bowel disease (IBD) at Cincinnati Children's Hospital Medical Center since 2007. Over the past years, we have adopted several programmes to improve health maintenance supervision for our paediatric patients with IBD but did not have a sustainable way to provide health maintenance updates for every patient at every encounter that was concise and complete in the setting of an increasing patient population and fewer support staff to complete the work. METHODS: Using quality improvement methods, we completed several Plan-Do-Study-Act (PDSA) cycles aimed at improving our centre's ability to provide complete health maintenance 'bundle' recommendations from 0% to 90% of patients over a period of 11 months. RESULTS: First steps included consensus gathering and summarising evidence into guidelines suitable for the group. PDSAs centred on consensus building from standardised guidelines, using empty checklists for simulated and real patients, and use of autofilled checklists. After several PDSA cycles, we have improved our ability to provide complete health maintenance PVP from 0% to nearly 100% with very little variation. CONCLUSION: Using the health maintenance PVP process, we can now sustainably provide health maintenance guidance for all outpatient clinic visits. We have begun to scale up this work and anticipate over the coming months that we will be able to expand the health maintenance PVP to provide complete PVP for over 90% of patients for any scheduled encounter including biologic infusion visits. We anticipate that using this reliable process we can improve remission rates and reduce preventable infections for these at-risk patients.

NASPGHAN Clinical Report on Postoperative Recurrence in Pediatric Crohn Disease.

Pediatric Crohn disease is characterized by clinical and endoscopic relapses. The inflammatory process is considered to be progressive and may lead to strictures, fistulas, and penetrating disease that may require surgery. In addition, medically refractory disease may be treated by surgical resection of inflamed bowel in an effort to reverse growth failure. The need for surgery in childhood suggests severe disease and these patients have an increased risk for recurrent disease and potentially more surgery. Data show that up to 55% of patients had clinical recurrence in the first 2 years after initial surgery. The current clinical report on postoperative recurrence in pediatric Crohn disease reviews the risk factors for early surgery and postoperative recurrence, operative risk factors for recurrence, and prevention and monitoring strategies for postoperative recurrence. We also propose an algorithm for postoperative management in pediatric Crohn disease.

Patient Health Communication Mediating Effects Between Gastrointestinal Symptoms and Gastrointestinal Worry in Pediatric Inflammatory Bowel Disease.

BACKGROUND: To investigate the effects of patient health communication regarding their inflammatory bowel disease (IBD) to their health care providers and significant others in their daily life as a mediator in the relationship between gastrointestinal symptoms and gastrointestinal worry in pediatric patients. METHODS: The Pediatric Quality of Life Inventory Gastrointestinal Symptoms, Gastrointestinal Worry, and Communication Scales, and Pediatric Quality of Life Inventory 4.0 Generic Core Scales were completed in a 9-site study by 252 pediatric patients with IBD. Gastrointestinal Symptoms Scales measuring stomach pain, constipation, or diarrhea and patient communication were tested for bivariate and multivariate linear associations with Gastrointestinal Worry Scales specific to patient worry about stomach pain or bowel movements. Mediational analyses were conducted to test the hypothesized mediating effects of patient health communication as an intervening variable in the relationship between gastrointestinal symptoms and gastrointestinal worry. RESULTS: The predictive effects of gastrointestinal symptoms on gastrointestinal worry were mediated in part by patient health communication with health care providers/significant others in their daily life. In predictive models using multiple regression analyses, the full conceptual model of demographic variables, gastrointestinal symptoms (stomach pain, constipation, or diarrhea), and patient communication significantly accounted for 46, 43, and 54 percent of the variance in gastrointestinal worry (all Ps < 0.001), respectively, reflecting large effect sizes. CONCLUSIONS: Patient health communication explains in part the effects of gastrointestinal symptoms on gastrointestinal worry in pediatric patients with IBD. Supporting patient disease-specific communication to their health care providers and significant others may improve health-related quality of life for pediatric patients with IBD.

Improving a process to obtain hepatitis B serology among patients treated with infliximab at a large urban children's hospital.

BACKGROUND: Hepatitis B infection is a significant public health challenge despite improvements in vaccination efforts. Patients such as those on chronic immunosuppressive therapy for inflammatory bowel disease (IBD) or rheumatic disease may incur greater risk. The risk of reactivation of hepatitis B while on immunosuppressive therapy may have mortality rates up to 25%. These patients should be screened for acute or chronic infection and vaccinated if necessary. Our aim was to reliably complete hepatitis B screenings in patients receiving infliximab at Cincinnati Children's Hospital Medical Center (CCHMC). METHODS: Eligible patients included all patients with gastroenterology (GI) IBD and rheumatology receiving infliximab between October 2015 and March 2016. Using quality improvement methodology and the 'plan-do-study-act' (PDSA) approach, interventions centred around education of clinical providers, previsit planning and the development of 'talking points' for patients. RESULTS: An initial screen of the IBD population revealed that 48% of the IBD patient population had been screened for anti-HBs alone, but no patients from GI or rheumatology divisions had a complete set of hepatitis B serology prior to the intervention including anti-Hep B Core and Hep B Surface Antigen. Seven PDSA cycles were performed during the 32-week intervention period, resulting in an increase in patients screened from 0% to ~85%. By March 2016, a total of 251 patients (201 GI, 50 rheumatology) had up-to-date hepatitis B serology screening. Automated ordering of the hepatitis B serology and 'talking points' for the provider had the greatest impact on successful screening. CONCLUSIONS: We developed a method to obtain hepatitis B serology on at-risk patients on infliximab within two subspecialty divisions within a large children's hospital. Next steps will be to develop a process to reliably provide vaccines for patients who are seronegative, expand this process to all patients who are identified as immunocompromised within GI and rheumatology and then expand this process to other divisions at the CCHMC.

Hepatic Issues and Complications Associated With Inflammatory Bowel Disease: A Clinical Report From the NASPGHAN Inflammatory Bowel Disease and Hepatology Committees.

Hepatobiliary disorders are common in patients with inflammatory bowel disease (IBD), and persistent abnormal liver function tests are found in approximately 20% to 30% of individuals with IBD. In most cases, the cause of these elevations will fall into 1 of 3 main categories. They can be as a result of extraintestinal manifestations of the disease process, related to medication toxicity, or the result of an underlying primary hepatic disorder unrelated to IBD. This latter possibility is beyond the scope of this review article, but does need to be considered in anyone with elevated liver function tests. This review is provided as a clinical summary of some of the major hepatic issues that may occur in patients with IBD.
