HLA DQA1*05 and risk of anti-TNF treatment failure and anti-drug antibody development in children with Crohn's Disease: HLA DQA1*05 and Pediatric Crohn's Disease.

Objectives: HLA DQA1*05 has been associated with the development of anti-drug antibodies (ADA) to tumor necrosis factor antagonists (anti-TNF) and treatment failure among adults with Crohn's disease (CD). However, findings from other studies have been inconsistent with limited pediatric data.

Methods: We analyzed banked serum from patients with CD < 21 years of age enrolled in COMBINE, a multi-center, prospective randomized trial of anti-TNF monotherapy vs.

Low Anti-Tumor Necrosis Factor Levels During Maintenance Phase Are Associated With Treatment Failure in Children With Crohn's Disease.

Background: Higher drug levels and combination therapy with low-dose oral methotrexate (LD-MTX) may reduce anti-tumor necrosis factor (TNF) treatment failure in pediatric Crohn's disease. We sought to (1) evaluate whether combination therapy with LD-MTX was associated with higher anti-TNF levels, (2) evaluate associations between anti-TNF levels and subsequent treatment failure, and (3) explore the effect of combination therapy on maintenance of remission among patients with therapeutic drug levels (>5 µg/mL for infliximab and >7.5 µg/mL for adalimumab).

Implementation and evaluation of an electronic consult program at a large academic health system.

Background: Although the benefits of eConsults in increasing access and lowering unnecessary utilization have been well described, the development of a successful program can be challenging.

Objective: We sought to share the experiences of a large academic health system in implementing and evaluating a high-volume electronic consultation (eConsult) program across 34 adult and pediatric medical and surgical specialties.

Methods: Using a multi-method approach, we collected qualitative and quantitative data on operational and process outcomes to describe adoption of eConsults, and survey data to capture satisfaction and experience among referring and specialist clinicians.

Isolated Terminal Ileitis in Children.

Isolated terminal ileitis in adults is a well described entity that rarely progresses to Crohn disease (CD), and pediatric literature on this topic is very limited. We describe the prevalence, clinical, endoscopic, histologic, and radiological features, along with long-term outcome of isolated terminal ileitis in our institution. We reviewed charts of 956 children who underwent colonoscopy from 2013 to 2017.

Sustained Improvement in Patient Experience by Optimizing Patient Flow in Ambulatory Settings.

Patient experience has become a priority for healthcare institutions as it affects clinical quality of care, financial reimbursement, provider, and patient satisfaction. We report our experience of improving patient experience measured by Press Ganey surveys in a busy multidisciplinary clinic over 65 months. We optimized patient flow in the clinic by technology-facilitated communication among the clinic staff and by a modest space redesign.

A Quality Improvement Project to Improve First Case On-time Starts in the Pediatric Operating Room.

Background: Delays in the operating room (OR) can lead to increased hospital costs as well as patient and provider dissatisfaction. Starting the first case on time in the OR can potentially prevent subsequent delays. We designed a quality improvement project to improve the first case on-time starts in the pediatric OR at a tertiary care children's hospital.

Implementing a Novel Quality Improvement-Based Approach to Data Quality Monitoring and Enhancement in a Multipurpose Clinical Registry.

Objective: To implement a quality improvement based system to measure and improve data quality in an observational clinical registry to support a Learning Healthcare System.

Data Source: ImproveCareNow Network registry, which as of September 2019 contained data from 314,250 visits of 43,305 pediatric Inflammatory Bowel Disease (IBD) patients at 109 participating care centers.

Study Design: The impact of data quality improvement support to care centers was evaluated using statistical process control methodology.

Complementary and Alternative Medicine Use in Children With Inflammatory Bowel Disease.

Complementary and alternative medicine (CAM) consists of products and practices that are not considered to be a part of conventional medicine. This article reviews pediatric studies on CAM in inflammatory bowel disease (IBD) along with relevant adult studies. Prevalence of CAM use ranges from 22% to 84% in children with IBD all over the world.

Prevalence of Anti-tissue Transglutaminase Antibodies and Celiac Disease in Children With Inflammatory Bowel Disease.

Objectives: Celiac disease can occur in children with inflammatory bowel disease (IBD) and poses a diagnostic challenge. We evaluated the presence of anti-tissue transglutaminase (tTG) antibodies and celiac disease among children with IBD.

Methods: In a retrospective chart review, we assessed the prevalence of tTG antibodies and celiac disease and compared with a control group of children with gastrointestinal symptoms without IBD.

Prevalence and Patterns of Marijuana Use in Young Adults With Inflammatory Bowel Disease.

Objectives: Recent studies in adults report symptom relief with marijuana use in patients with inflammatory bowel disease (IBD). We assessed the prevalence, pattern, effects, and adverse effects of marijuana use in young adults with IBD.

Methods: We conducted a prospective questionnaire survey study at a pediatric IBD clinic.

Correlation of Erythrocyte Sedimentation Rate and C-Reactive Protein With Pediatric Inflammatory Bowel Disease Activity.

We aimed to examine correlation of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) with diagnosis of inflammatory bowel disease and with clinical, endoscopic, histological, and radiographic disease activity during follow-up. We reviewed charts of 135 children with inflammatory bowel disease and correlated their ESR and CRP values with disease activity in various encounters during 5 years. Normal ESR and CRP values were observed in up to 28% of children with Crohn disease and 42% of children with ulcerative colitis at diagnosis, respectively.

Prevalence and Clinical, Endoscopic, and Pathological Features of Duodenitis in Children.

Objectives: Although gastritis and esophagitis are well studied in children, there is very limited literature on duodenitis in children. We aimed to assess the prevalence, etiology, clinical, endoscopic, and pathological features in a large cohort of unselected children with duodenitis.

Methods: We reviewed the pathology reports of all the upper endoscopies performed at our institution during 5 years to identify children with duodenitis.

Obesity and gastrointestinal disorders in children.

Obesity in children has become a global pandemic during the last decade. Recent studies have reported an association between obesity and functional gastrointestinal (GI) disorders. In addition, obesity is also becoming increasingly recognized at diagnosis of organic GI diseases such as celiac disease and inflammatory bowel disease.

Histopathology of duodenal mucosal lesions in pediatric patients with inflammatory bowel disease: statistical analysis to identify distinctive features.

Histopathologic lesions of the upper gastrointestinal tract (UGT) are common in inflammatory bowel disease (IBD) patients. Pediatric patients have a higher incidence of IBD-associated gastritis and duodenitis than do adults. This study aimed to identify histopathologic features of duodenal lesions in the pediatric population that are characteristic of IBD, compared to duodenal pathology of different etiopathogenesis.

Individual exome analysis in diagnosis and management of paediatric liver failure of indeterminate aetiology.

Background & Aims: In children with liver failure, as many as half remain of indeterminate aetiology. This hinders timely consideration of optimal treatment options. We posit that a significant subset of these children harbour known inherited metabolic liver diseases with atypical presentation or novel inborn errors of metabolism.
