Development and implementation of the AIDA International Registry for patients with VEXAS syndrome

Objective: The aim of this paper is to present the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome, describing its design, construction, and modalities of dissemination. Methods: The present registry is a clinical, physician-driven, population- and electronic-based instrument designed for the retrospective and prospective collection of real-life data. Data gathering is based on the Research Electronic Data Capture (REDCap) tool and is intended to obtain real-world evidence for daily patients’ management; the registry may potentially communicate with other on-line tools dedicated to VEXAS syndrome, enhancing international collaboration and data sharing for research purposes. The registry is handy enough to be easily modified to meet future needs regarding VEXAS syndrome. Results: To date (April 2022), 105 Centers from 23 Countries in 4 continents have been involved; 287 users (106 Principal Investigators, 177 Site Investigators, 2 Lead Investigators, and 2 data managers) may already enter the registry for data collection and sharing. The registry includes 4950 fields organised into 18 instruments designed to fully describe patient’s details about demographics, clinical manifestations, symptoms, histologic details about skin and bone marrow biopsies and aspirate, laboratory features, complications, comorbidities, therapies, and healthcare access. Conclusions: This international Registry for patients with VEXAS syndrome will allow the achievement of a comprehensive knowledge about this new disease in a relatively short time with the final goal to obtain real-world evidence data for daily clinical practice.
