Monti S, Quinn KA, Christensen R, et al. - A systematic literature review of randomized trials was conducted to evaluate the use and reporting of outcome measures in randomized trials for anti-neutrophil cytoplasmic antibody-associated vasculitis. Researchers performed a systematic literature review of outcome measures (as specified in the methods section as primary and/or secondary outcomes) in randomized controlled trials (RCTs) of ANCA-associated vasculitis (AAV). This study was carried out to search Medline, Cochrane CENTRAL, and ClinicalTrials.gov were searched from inception until April 30, 2019, for RCTs enrolling patients with granulomatosis with polyangiitis and/or microscopic polyangiitis. In this study, 68 RCTs were eligible out of 1101 identified records. For disease evaluation, outcome measures applied in AAV trials commonly included vasculitis-specific tools, but with heterogeneity in endpoint-definitions and timing of assessments. The data revealed that in AAV, other core outcomes, including patient-reported outcomes, and damage measures, are often omitted in AAV trials.
