Feedback received in the OMERACT community around the 3 projects is given in the sections below. Open in a separate window Figure 1 The OMERACT Filter 2.0 Instrument Selection Algorithm (OFISA) and red-amber-green checklist. OMERACT delegates endorsed the use of the PROMIS devices for fatigue, physical functioning, and pain interference (87.6% overall endorsement) and the disease-specific AAV-PRO instrument (89.4% overall endorsement). Conclusion The OMERACT Vasculitis Working Group gained endorsement by OMERACT for use of the PROMIS and the AAV-PRO in clinical trials of vasculitis. These devices are complementary to each other. The PROMIS and the AAV-PRO need further work to assess their power in longitudinal settings, including their ability to discriminate between treatments of varying efficacy in the setting of a randomized controlled trial. strong class=”kwd-title” Key Indexing Terms: ANCA-ASSOCIATED VASCULITIS, PATIENT-REPORTED OUTCOMES, PROMIS, ICF, OMERACT Antineutrophil cytoplasmic antibodyCassociated vasculitis (AAV) consists of 3 multisystem diseases caused by inflammation of the small blood vessels: granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis (Churg-Strauss), and microscopic polyangiitis. Because of their relative rarity and overlapping disease features, these vasculitides are commonly studied together within randomized controlled trials (RCT)1. Modern therapeutic regimens, including high-dose glucocorticoids and immunosuppressive medications, have transformed AAV from a nearly universally fatal disease to a usually treatable problem2. However, patients still often experience persistent and/or relapsing disease and irreversible damage3 from the effects of both the disease manifestations and the toxicities of treatments4. From the onset of disease in AAV, patients health-related quality of life (HRQOL) is usually impaired5. There is a discrepancy between the perspectives of patients with AAV, who rank constitutional symptoms such as fatigue/reduced energy levels as having the best relevance to their disease, and that of their physicians, who rank the effects of organ damage such as requirement for renal replacement therapy or oxygen dependence as being of greater importance6. Therefore, it is essential to collect patient-reported outcomes (PRO) within clinical trials of new treatment regimens to ensure that outcomes of importance to patients are accurately measured7. Generic HRQOL instruments, such as the Medical Outcomes Study Short Form-36 (SF-36) or the EQ-5D, can be applied in a range of different disease populations and interventions GDC-0449 (Vismodegib) and facilitate comparisons between both diseased and general populations8. However, these tools may not be specific enough to identify Mouse monoclonal to DKK3 the complexity of experiences of patients within particular diseases. Disease-specific instruments, for example the Rheumatoid Arthritis Impact of Disease score9 or the Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire10, may perform better at identifying such experiences. It is generally recommended that both generic steps and disease-specific PRO be GDC-0449 (Vismodegib) used to provide a comprehensive and relevant description of any individual population11. In 2010 2010, the Outcome Steps in Rheumatology (OMERACT) Vasculitis Working Group received endorsement for a core set of domains and outcome measures for use in clinical trials in AAV12. Within the patient-reported outcome domain name, the SF-36 was presented as GDC-0449 (Vismodegib) the generic instrument for GDC-0449 (Vismodegib) use in AAV12. The lack of a disease-specific PRO and the relative lack of research into PRO in vasculitis were noted12. The SF-36 was included in the core set because it can discriminate between disease says of importance in AAV, i.e., remission versus active disease, and its scores correlate moderately well with disease activity, as measured by the clinician-completed Birmingham Vasculitis Activity Score/WG13. However, there have been concerns that this SF-36 does not sufficiently identify specific disease manifestations identified by patients with AAV as being important6,14,15. The OMERACT Vasculitis Working Group established a strategy to analyze the patient perspective in more depth, and to develop and/or validate new PRO for use in clinical trials of AAV. This strategy has been facilitated through workshops held at the 2012 and 2014 OMERACT conferences, 2 face-to-face meetings in the United States and United Kingdom, and monthly teleconferences with an international Steering Committee of patient partners, qualitative and quantitative GDC-0449 (Vismodegib) methodologists, and clinician investigators16.
