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.

Assuring Quality for Non-hospital-based Biologic Infusions in Pediatric Inflammatory Bowel Disease: A Clinical Report From the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

The primary aim of this Clinical Report by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition is to provide formal guidance to pediatric gastroenterologists and clinicians, health systems, and insurance payers regarding home- and office-based infusions for biologic therapies in pediatric inflammatory bowel disease. Patients in North America are increasingly denied coverage by payers based on "place of service" codes at hospital-based infusion units where the treating clinicians primarily provide care. A task force with topic expertise generated 8 best practice recommendations to ensure quality of care for pediatric patients with inflammatory bowel disease receiving non-hospital-based biologic infusions. Pragmatic considerations discussed in this report include patient safety, pediatric-trained nurse availability, care coordination, patient-centeredness, shared liability, administrative support, clinical governance, and costs of care.

Appropriateness of emergency department use in pediatric inflammatory bowel disease: a quality improvement opportunity.

OBJECTIVES: We sought to characterize emergency department (ED) encounters for pediatric inflammatory bowel disease (IBD) to identify areas for prevention. METHODS: Retrospective chart review of 5 consecutive ED encounters at 7 centers was performed. RESULTS: Of 35 unique encounters by 32 patients, 3 main factors contributed to ED utilization: disease severity or course, day or time of care, and physician instruction. Of the ED encounters, approximately one-fifth were judged medically unnecessary, and one-half avoidable in a more optimal health care system. CONCLUSIONS: ED visits by pediatric patients with IBD may be reduced in a more optimal health care system.

Quality Improvement Methodology Optimizes Infliximab Levels in Pediatric Patients with Inflammatory Bowel Disease.

Achieving and maintaining target serum trough infliximab levels improves outcomes in children and young adults with inflammatory bowel disease. Our goal was to improve adherence to an infliximab therapy guideline. The primary aim was to increase the percentage of patients with infliximab levels ≥5 µg/mL and results checked in the last 12 months from 73% to ≥80% from July 2017 to January 2018. METHODS: We participated in Intermediate Improvement Science Series, a course at Cincinnati Children's Hospital Medical Center designed to catalyze change using quality improvement methodology. We implemented interventions through plan-do-study-act cycles. Our outcome measure was balanced by 2 process measures to determine what actions impacted improvement. These measures included the percentage of infusion plans revised in response to a drug level <5 µg/mL and the proportion of plans for which a follow-up drug level was ordered. RESULTS: We increased the percentage of infusion plans revised before the next infusion from 63% to 87% and the percentage of plans that had an appropriate drug level recheck from 61% to 83% from July 2017 to January 2018. We increased the percentage of patients with an infliximab level >5 µg/mL, and results checked in the last 12 months, from 73% to 80%. CONCLUSIONS: Quality improvement methodology was effective in improving provider adherence to infliximab therapeutic drug monitoring guidelines. Improvement in adherence to guidelines directly improved the percentage of patients achieving target infliximab levels at any time during infliximab therapy.

Maintaining Hepatitis B Protection in Immunocompromised Pediatric Rheumatology and Inflammatory Bowel Disease Patients.

OBJECTIVE: Hepatitis B virus (HBV) infection remains a significant public health challenge, particularly for immunocompromised patients. Our aim was to evaluate the serologic immunity in immunocompromised rheumatology and inflammatory bowel disease (IBD) patients, assess factors for serologic nonimmunity, and evaluate their response to 1 HBV booster dose. METHODS: Immunocompromised rheumatology and IBD patients with completed HBV screening were identified. A chart review was performed to collect demographics, clinical information, baseline HBV serology results, and serologic response to booster vaccination. Serologic nonimmunity was defined as a negative/indeterminate hepatitis B surface antibody (anti-HBs) level. RESULTS: Among 580 patients, 71% were nonimmune. The highest portion of nonimmune patients were 11-18 years old (P = 0.004). There was no significant difference between immune and nonimmune patients with regards to diagnosis (P = 0.34), age at diagnosis (P = 0.64), duration of treatment (P = 0.07), or type of medications (P = 0.08). Sixty-two percent of those who received a booster vaccine were rescreened, and most (68%) seroconverted. In those 18 years or older, only half seroconverted. CONCLUSION: Results of this study support the benefit of HBV screening in immunosuppressed patients. Beginning at age 11 years, most patients lacked serologic immunity to HBV. Seroconversion for most patients 11-18 years occurred after 1 booster vaccine. Thus, for immunocompromised patients without recent HBV serologic data, obtaining the HBV serology beginning at age 11 years might be considered. Those 18 years and older were least likely to seroconvert after 1 booster, indicating that they may benefit from receiving the 3-dose HBV vaccine series.

Effect of a Practice-wide Anti-TNF Proactive Therapeutic Drug Monitoring Program on Outcomes in Pediatric Patients with Inflammatory Bowel Disease.

BACKGROUND: Reports on the feasibility and effectiveness of translating proactive, antitumor necrosis factor (TNF) therapeutic drug monitoring (TDM) for inflammatory bowel disease into practice-wide quality improvement (QI) are lacking. We aimed to determine whether a TDM QI program improved outcomes at a large academic pediatric gastroenterology practice. METHODS: We instituted local anti-TNF TDM practice guidelines to proactively monitor and optimize drug levels (goal >5 µg/mL). We conducted a retrospective single-center cohort analysis of patient outcomes before (pre-TDM) and after (post-TDM) guideline institution and assessed the independent effect by multivariable regression. Primary outcome was sustained clinical remission (SCR22-52), defined as physician global assessment (PGA) of inactive from 22 to 52 weeks and off corticosteroids at 52 weeks. RESULTS: We identified 108 pre-TDM and 206 post-TDM patients. The SCR22-52 was achieved in 42% of pre-TDM and 59% of post-TDM patients (risk difference, 17.6%; 95% CI, 5.4-29%; P = 0.004). The post-TDM group had an increased adjusted odds of achieving SCR22-52 (odds ratio, 2.03; 95% CI, 1.27-3.26; P = 0.003). The adjusted risk of developing high titer antidrug antibodies (ADAs) was lower in the post-TDM group (hazard ratio, 0.18; 95% CI, 0.09-0.35; P < 0.001). Although the risk of anti-TNF cessation for any reason was not significantly different, there was a lower adjusted risk of cessation related to any detectable ADA in the post-TDM group (hazard ratio, 0.45; 95% CI, 0.26-0.77; P = 0.003). CONCLUSIONS: A practice-wide proactive anti-TNF TDM QI program improved key clinical outcomes at our institution, including sustained clinical remission, incidence of high titer ADA, and anti-TNF cessation related to ADA.

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.

Integrating Psychological Screening Into Medical Care for Youth With Abdominal Pain.

BACKGROUND: Pediatric functional abdominal pain disorders are common, costly, and disabling. Clinical anxiety is highly prevalent and is associated with increased pain and functional disability. Thus, a psychological screening process is recommended but is infrequently used in current practice. METHODS: A screening process for patient-reported anxiety (Screen for Child Anxiety and Related Disorders), functional disability (Functional Disability Inventory), and pain levels was implemented in a large gastroenterology division within a major medical center. Quality improvement methods and traditional analytic approaches were used to test the feasibility and outcomes of routine screening in patients ages 8 to 18 with abdominal pain. RESULTS: Screening rates increased from <1% to >80%. A total of 1291 patients who reported having abdominal pain completed the screening during the first 6 months. Clinically significant anxiety (43.1%), at least moderate disability (45%), and elevated pain (61.5%) were common in children with abdominal pain. The presence of clinically significant anxiety corresponded with higher pain and pain-related disability. Twenty-one percent of youth had clinical elevations in all 3 areas. In such instances, medical providers received an automated prompt to tailor care, including to consider a psychological referral. After the project implementation, psychological referral rates increased from 8.3 per 1000 patients to 15.2 per 1000 patients. CONCLUSIONS: Systematic screening for anxiety, pain, and pain-related disability as a routine part of medical care can be reliably implemented with clinically meaningful results. Future directions include examining the role of anxiety over the long-term and reducing clinician burden.

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.

Protocol of a Pilot Study of Technology-Enabled Coproduction in Pediatric Chronic Illness Care.

BACKGROUND: Pediatric chronic illness care models are traditionally organized around acute episodes of care and may not meet the needs of patients and their families. Interventions that extend the patient-clinician interaction beyond the health care visit, allow for asynchronous and bidirectional feedback loops that span visits and daily life, and facilitate seamless sharing of information are needed to support a care delivery system that is more collaborative, continuous, and data-driven. Orchestra is a mobile health technology platform and intervention designed to transform the management of chronic diseases by optimizing patient-clinician coproduction of care. OBJECTIVE: The aim of this study is to assess the feasibility, acceptability, and preliminary impact of the Orchestra technology and intervention in the context of pediatric chronic illness care. METHODS: This study will be conducted in the cystic fibrosis and inflammatory bowel disease clinics at Cincinnati Children's Hospital Medical Center. We will enroll interested patients and their caregivers to work with clinicians to use the Orchestra technology platform and care model over a 6-month period. In parallel, we will use quality improvement methods to improve processes for integrating Orchestra into clinic workflows and patient/family lifestyles. We will use surveys, interviews, technology use data, and measures of clinical outcomes to assess the feasibility, acceptability, and preliminary impact of Orchestra. Outcome measures will include assessments of: (1) enrollment and dropout rates; (2) duration of engagement/sustained use; (3) symptom and patient-reported outcome tracker completion rates; (4) perceived impact on treatment plan, communication with the clinical team, visit preparation, and overall care; (5) changes in disease self-efficacy and engagement in care; and (6) clinical outcomes and health care utilization. RESULTS: Participant recruitment began in mid-2015, with results expected in 2017. CONCLUSIONS: Chronic disease management needs a dramatic transformation to support more collaborative, effective, and patient-centered care. This study is unique in that it is testing not only the impact of technology, but also the necessary processes that facilitate patient and clinician collaboration. This pilot study is designed to examine how technology-enabled coproduction can be implemented in real-life clinical contexts. Once the Orchestra technology and intervention are optimized to ensure feasibility and acceptability, future studies can test the effectiveness of this approach to improve patient outcomes and health care value.

Rapid Infliximab Infusion in Children with Inflammatory Bowel Disease: A Multicenter North American Experience.

BACKGROUND: Infliximab (IFX) infusion may lead to development of anti-IFX antibodies, and subsequent infusion reactions (IRs). The safety of rapid IFX infusion administered over 60 minutes has been under-investigated in children with inflammatory bowel disease. In a multicenter study, the frequency and nature of rapid infusion-associated IRs were examined. METHODS: The medical records of all consecutive children with inflammatory bowel disease receiving rapid IFX infusions between January 2014 and December 2016 were reviewed. Poisson regression analysis was used to identify possible associated factors with IRs. RESULTS: A total of 4120 rapid infusions for 453 children (median age 16 yrs [interquartile range 13.8-17.8], 289 males, 374 with Crohn's disease) were included. One hundred thirty-five participants (29.8%) received rapid IFX infusion for induction and maintenance while the rest received rapid IFX infusion after a median of 5 (interquartile range 4-9) standard infusions. The median dose of IFX using rapid protocol was 8 mg/kg/infusion (interquartile range 6-10). Two hundred sixty-seven (59%) patients received 1 or more premedications and 161 (35.5%) participants received concomitant immunosuppression. Twenty-one participants (4.6%) had IRs with rapid infusions and 2 participants discontinued IFX because of IRs (0.4%). Antihistamine premedications were associated with less frequent IR (adjusted relative risk = 0.30; 95% confidence interval, 0.14-0.64; P = 0.002). CONCLUSIONS: In children with inflammatory bowel disease, rapid IFX infusion administered over 60 minutes is safe and well-tolerated. Antihistamine premedications may reduce frequency of IRs (see Video Abstract, Supplemental Digital Content 1, http://links.lww.com/IBD/B632).

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.

Improving pediatric Inflammatory Bowel Disease (IBD) follow-up.

Standardization of Inflammatory Bowel Disease (IBD) care through participation in the ImproveCareNow (ICN) Network has improved outcomes for pediatric patients with IBD, but under the current care model, our improvements have plateaued. Current ICN model care guidelines recommend health supervision visits every six months. We identified a gap in our practice's ability to ensure either a routine six month follow-up or a rapid follow-up after a disease flare, and a significant number of patients with active disease status during a six month period lacked timely reassessment after interventions or medication changes. Telemedicine provides an alternative method of care delivery to address these gaps, but has had limited use in patients with IBD. A multi-step approach to offer alternative follow-up care options via telemedicine was developed with potential impact on remission rates and quality of life. Short term goals of the pilot were to improve telemedicine access for patients with IBD were to 1) increase the percent of patients with active disease with a follow-up completed within two months of a visit from 40% to 70%, 2) increase the percent of patients with a visit scheduled within two months of their last sick visit from 20% to 70% (interim measure), 3) increase the number of eVisits from zero visits per month to two visits per month during pilot phase, 4) increase electronic communication with patients from zero messages per month to 200 messages per month, 5) no change in complications or adverse events (defined as an unplanned visit or ED (emergency department) encounter within 30 days of an eVisit. The expected outcomes of the e-visit model were to: maintain baseline care standards and health screening capabilities, improve access to care, and provide equivalent care delivery (no increase in the number of unplanned clinical encounters). Using the IHI model for improvement (Plan-Do-Study-Act) we have seen a progressive increase in the rate of patient signups for the electronic medical record patient portal, with a baseline median of 20% per clinic compared with a current median of approximately 70% after six months. We successfully implemented e-messaging in its pilot form among five providers and have seen steady uptake in patient use from 5 patient initiated messages during the first month to 76 messages/month over the past three months. E-visits have replaced a total of 32 visits to date. Medications, nutrition, and disease activity were appropriately screened and managed electronically without the need for a physical office visit by the treating gastroenterologist. Access to care was improved in that all patients completed their e-visits from their homes without missing school or work and did not require a physical office visit. One visit successfully identified worsening of the patient's clinical course and resulted in a scheduled office visit request, but no unplanned office visits or ED visits have occurred. This report represents the first description of telemedicine use in routine clinical care in children with IBD. We anticipate continuing use of this novel mode of health care delivery in pediatrics in an effort to increase the proportion of patients seen for interval follow-up, after IBD diagnosis, or mild flare in an effort to target early treatment changes that should result in improved remission and patient reported outcomes. E-visits are less expensive and time consuming than traditional visits and may serve as an additional method of cost savings by matching care to a patient's individual needs.

Implementable strategies and exploratory considerations to reduce costs associated with anti-TNF therapy in inflammatory bowel disease.

A health care system is needed where care is based on the best available evidence and is delivered reliably, efficiently, and less expensively (best care at lower cost). In gastroenterology, anti-tumor necrosis factor agents represent the most effective medical therapeutic option for patients with moderate-to-severe inflammatory bowel disease (IBD), but are very expensive and account for nearly a quarter of the cost of IBD care, representing a major area of present and future impact in direct health care costs. The ImproveCareNow Network, consisting of over 55 pediatric IBD centers, seeks ways to improve the value of care in IBD, curtailing unnecessary costs and promoting better health outcomes through systematic and incremental quality improvement initiatives. This report summarizes the key evidence to facilitate the cost-effective use of anti-tumor necrosis factor agents for patients with IBD. Our review outlines the scientific rationale for initiating cost-reducing measures in anti-tumor necrosis factor use and focuses on 3 implementable strategies and 4 exploratory considerations through practical clinical guidelines, as supported by existing evidence. Implementable strategies can be readily integrated into today's daily practice, whereas exploratory considerations can guide research to support future implementation.

Increased prevalence of luminal narrowing and stricturing identified by enterography in pediatric Crohn's disease patients with elevated granulocyte-macrophage colony stimulating factor autoantibodies.

BACKGROUND: Crohn's disease (CD) patients with elevated granulocyte-macrophage colony-stimulating factor autoantibodies (GM-CSF Ab) are more likely to develop stricturing behavior requiring surgery. Computed tomography or magnetic resonance enterography (CTE or MRE) may detect luminal narrowing (LN) before stricture development. The objective of this study was to determine whether CD patients with elevated GM-CSF Ab (≥1.6 µg/mL) have a higher prevalence of LN and stricturing on CTE or MRE. METHODS: A single-center, cross-sectional study of 153 pediatric patients with CD and control subjects undergoing diagnostic CTE or MRE. Examinations were evaluated for disease activity using a novel scoring system and for the presence of LN, stricture, intra-abdominal abscess, or fistulae. Dichotomous outcomes were compared with respect to antibody status (high or low) using Fisher's exact test and logistic regression, whereas continuous outcomes were evaluated using unpaired t test. RESULTS: GM-CSF Ab were elevated in CD patients (n = 114) with a median (interquartile range) GM-CSF Ab level of 2.3 µg/mL (0.5-6.6 µg/mL) compared with 0.6 µg/mL (0.3-1.3 µg/mL) in healthy and disease control subjects (n = 39) (P = 0.001). Ileal disease location was more common in CD patients with high GM-CSF Ab (P < 0.001). LN increased from 39% in CD patients with low GM-CSF Ab to 71% in those with high levels (P = 0.004) and remained significantly associated with high GM-CSF Ab in a multivariate logistic model, which included age, gender, small bowel location, and duration of disease. Stricturing prevalence on CTE or MRE examination increased from 4% in CD patients with low GM-CSF Ab to 19% in those with high GM-CSF Ab (P = 0.03). CONCLUSIONS: Pediatric CD patients with high GM-CSF Ab levels have a higher prevalence of LN on CTE or MRE. Further study will be needed to determine whether medical therapy will reduce progression to stricturing behavior in these patients.

Mycophenolate mofetil-related enterocolitis and weight loss: a pediatric case series.

Mycophenolate mofetil (MMF) is an immunosuppressive medication utilized in the management of both autoimmune and solid organ transplant patients. Diarrhea is a common gastrointestinal side effect of MMF, but more severe forms of GI symptoms are described in renal transplant patients with a distinct pattern of histopathologic change, similar to graft-versus-host disease or Crohn's disease. This rare entity, commonly referred to as "MMF-related enterocolitis," has been described in adult patients, mostly in renal transplant patients, and in only two pediatric renal transplant patients. In previously reported cases, symptoms and abnormal histopathology improve with dose reduction of MMF. We describe a series of three pediatric patients with varied underlying disease process who presented with severe diarrhea and histopathologic findings characteristic of MMF-related enterocolitis, who share a novel finding of weight loss as a complication of MMF-related enterocolitis in pediatric patients.
