Background:AAV (ANCA-associated vasculitis) is a group of progressive, rare, severe autoimmune diseases1,2. AAV can affect blood vessels in different parts of the body resulting in damage to vital organs such as the lungs, kidneys, nervous system, gastrointestinal system, skin, eyes, and heart.2 There are currently no approved therapies for remission-induction in patients with AAV. The current treatment armamentarium for AAV is comprised of various immunosuppressive therapies in combination with steroid treatment. Understanding clinical practice gaps in the management of AAV, can inform development of tools to improve physician practices.Objectives:This medical education activity aims to assess physicians’ knowledge on the various manifestations of antineutrophil cytoplasmic antibody-associated vasculitis (AAV), current guideline-recommended treatment strategies for remission induction in patients with AAV, as well as recent clinical trial data for combination therapies used for remission induction.Methods:A 24-question survey consisting of multiple-choice knowledge and case-based questions was made available to nephrologists and rheumatologists without monetary compensation or charge. The questions were designed to evaluate knowledge regarding the various manifestations of AAV and the results from clinical trials that have compared the efficacy of combination therapies used for remission induction in patients with AAV. As well as application of guideline-recommended therapies and clinical trial data for remission induction in patients with AAV within clinical practice. The survey launched online on a website dedicated to continuous professional development. (www.medscape.org/viewarticle/920320) on July 15, 2020. Data were collected until October 1, 2020.Results:363 nephrologists and 190 rheumatologists completed the survey. Physicians demonstrated gaps in the following areas:TopicIncorrect Responses to Knowledge and Clinical Decision-Making Questions (%)NephrologistsRheumatologistsSystemic diseases associated with AAV59%45%How to confirm diagnosis of AAV42%25%Therapy selection to induce remission that would be consistent with guidelines recommendations71%51%Guideline-recommended therapy for patients that do not respond to the induction regimen32%34%Definition of refractory disease95%94%Most effective maintenance strategy for a patient once remission is achieved80%64%Where would an emerging therapy such as a C5a receptor inhibitor fit into the therapeutic armamentarium of AAV?62%47%What are the guideline-recommended therapies to reduce remission in patients without organ-threatening disease?71%51%Most effective maintenance strategy for a patient once remission is achieved80%64%Guideline-recommendations on length of time to continue maintenance therapy31%35%Conclusion:This educational research on assessment of physicians’ (nephrologists and rheumatologists) clinical practices yielded important insights into clinical gaps related to understanding of the disease pathophysiology and progression of AAV, guideline recommendations on diagnosing and managing AAV with guideline-directed medical therapies (GDMTs), strategies for the management of relapsing and refractory disease in AAV and positioning of emerging therapies in the treatment paradigm.References:[1]www.medscape.org/viewarticle/920320.[2]Hutton HL, et al.
