    Creating a multi-center rare disease consortium - the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR)
    (IOS Press, 2017-12-18) Cheng, Katherine; Gupta, Sandeep K.; Kantor, Susanna; Kuhl, Jonathan T.; Aceves, Seema S.; Bonis, Peter A.; Capocelli, Kelley E.; Carpenter, Christina; Chehade, Mirna; Collins, Margaret H.; Dellon, Evan S.; Falk, Gary W.; Gopal-Srivastava, Rashmi; Gonsalves, Nirmala; Hirano, Ikuo; King, Eileen C.; Leung, John; Krischer, Jeffrey P.; Mukkada, Vincent A.; Schoepfer, Alain; Spergel, Jonathan M.; Straumann, Alex; Yang, Guang-Yu; Furuta, Glenn T.; Rothenberg, Marc E.; Pediatrics, School of Medicine
    Eosinophilic gastrointestinal disorders (EGIDs) affect various segments of the gastrointestinal tract. Since these disorders are rare, collaboration is essential to enroll subjects in clinical studies and study the broader population. The Rare Diseases Clinical Research Network (RDCRN), a program of the National Center for Advancing Translational Sciences (NCATS), funded the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) in 2014 to advance the field of EGIDs. CEGIR facilitates collaboration among various centers, subspecialties, patients, professional organizations and patient-advocacy groups and includes 14 clinical sites. It has successfully initiated two large multi-center clinical studies looking to refine EGID diagnoses and management. Several pilot studies are underway that focus on various aspects of EGIDs including novel therapeutic interventions, diagnostic and monitoring methods, and the role of the microbiome in pathogenesis. CEGIR currently nurtures five physician-scholars through a career training development program and has published more than 40 manuscripts since its inception. This review focuses on CEGIR's operating model and progress and how it facilitates a framework for exchange of ideas and stimulates research and innovation. This consortium provides a model for progress on other potential clinical areas.

    PedsQL™ Eosinophilic Esophagitis Module: Feasibility, Reliability and Validity
    (Wiley, 2013) Franciosi, James P.; Hommel, Kevin A.; Bendo, Cristiane B.; King, Eileen C.; Collins, Margaret H.; Eby, Michael D.; Marsolo, Keith; Abonia, J. Pablo; von Tiehl, Karl F.; Putnam, Philip E.; Greenler, Alexandria J.; Greenberg, Allison B.; Bryson, Ronald A.; Davis, Carla M.; Olive, Anthony P.; Gupta, Sandeep K.; Erwin, Elizabeth A.; Klinnert, Mary D.; Spergel, Jonathan M.; Denham, Jolanda M.; Furuta, Glenn T.; Rothenberg, Marc E.; Varni, James W.; Pediatrics, School of Medicine
    Objective: Eosinophilic esophagitis (EoE) is a chronic esophageal inflammatory condition with a paucity of information on health-related quality of life (HRQOL). The objective of the study was to report on the measurement properties of the PedsQL EoE Module. Methods: The PedsQL EoE Module was completed in a multisite study by 196 pediatric patients with EoE and 262 parents of patients with EoE. Results: The PedsQL EoE Module scales evidenced excellent feasibility (0.6%-3.1% missing), excellent group comparison reliability across total scale scores (patient α 0.93; parent proxy α 0.94), good reliability for the 7 individual scales (patient α 0.75-0.87; parent proxy α 0.81-0.92), excellent test-retest reliability (patient intraclass correlation coefficient 0.88; parent intraclass correlation coefficient 0.82), demonstrated no floor effects and low ceiling effects, and demonstrated a high percentage of scaling success for most scales. Intercorrelations with the PedsQL Generic Core Scales were in the medium (0.30) to large (0.50) range. PedsQL EoE Module scores were worse among patients with active histologic disease (≥ 5 eos/hpf) compared with those in remission (patient self-report: 63.3 vs 69.9 [P < 0.05]; parent proxy report: 65.1 vs 72.3 [P < 0.01]), and those treated with dietary restrictions compared with those with no restrictions (patient self-report: 61.6 vs 74.3 [P < 0.01]; parent proxy report: 65.5 vs 74.7 [P < 0.01]). Conclusions: The results demonstrate excellent measurement properties of the PedsQL EoE Module. Patients with active histologic disease and those treated with dietary restrictions demonstrated worse PedsQL scores. The PedsQL EoE Module may be used in the evaluation of pediatric EoE disease-specific HRQOL in clinical research and practice.
