BACKGROUND: ANCA-associated vasculitis (AAV) is a rare multisystem autoimmune disease in which diagnostic delay remains common and contributes to organ damage. This study aimed to develop a multispecialty, consensus-based set of clinical, laboratory, and imaging red flags to facilitate early recognition across medical disciplines.
METHODS: A structured consensus process inspired by modified Delphi methodology and the RAND/UCLA Appropriateness Method was conducted. A multispecialty panel including rheumatologists, nephrologists, and specialists in internal medicine, otolaryngology, pulmonology, ophthalmology, and neurology evaluated a comprehensive list of AAV manifestations. All items were scored on a 0-10 relevance scale through inter-specialty voting. Following five intra-specialty Scientific Discussion Sessions to interpret scores and refine items, a second-round evaluation was performed, and a final meeting validated the definitive checklist.
RESULTS: Organ-specific manifestations without a better explanation involving the upper airways, kidneys, nervous system, lungs, and eyes were consistently rated as the most relevant red flags for early AAV recognition. High relevance was attributed to refractory ENT (Ear, Nose and Throat) disease, active urinary sediment, otherwise unexplained central or peripheral neurological deficits in young individuals, inflammatory ocular involvement, and pulmonary hemorrhagic features. Systemic symptoms showed lower relevance scores and were considered supportive rather than specific indicators. In parallel, a unified panel of first-level laboratory and instrumental investigations was defined to facilitate early multisystem assessment when AAV is suspected.
CONCLUSIONS: This multispecialty consensus-based checklist provides a pragmatic tool to support early suspicion of AAV in routine clinical practice and may help reduce diagnostic delay.
