    Abstract Objective: Relapses are frequent and difficult to predict in antineutrophil cytoplasmic antibody-associated vasculitis (AAV), resulting in long-term use of immunosuppression. Although sinonasal disease is associated with relapse of AAV, detailed characterization of sinonasal symptoms is lacking. Using a patient-reported outcome, the 22-item SinoNasal Outcome Test (SNOT-22), we investigated the relationship between sinonasal symptoms and disease activity in AAV.
    Methods: This was a prospective, longitudinal study of individual with AAV and healthy individuals. Relapse was defined as a Birmingham Vasculitis Activity Score for Wegner's Granulomatosis score >0. Higher SNOT-22 scores indicate worse symptoms. Generalized estimating equation and Cox proportional hazard models evaluated the association between SNOT-22 and relapse.
    Results: There were 773 visits (106 active disease visits) from 168 patients with AAV and 51 controls. Median SNOT-22 at remission was higher in AAV versus controls (20 vs 5; P < 0.001) and higher during active disease versus remission (P < 0.001). In all AAV, and particularly within granulomatosis with polyangiitis, higher SNOT-22 scores were observed months to years before relapse and were associated with increased risk of relapse (hazard ratio 2.7, 95% confidence interval 1.2-6.2; P = 0.02). Similar findings were seen when examining patients with versus without sinonasal disease and after removing relapses limited to the ear, nose, and throat.
    Conclusion: A patient-reported outcome measure of sinonasal disease, the SNOT-22, not only changes with disease activity in AAV, but also is associated with a higher risk of relapse within two years. These findings support the possibility that the SNOT-22 score may enhance prediction of relapse and that persistent sinonasal disease may be important in the pathophysiology of relapse.

    Abstract Objectives: To determine the incidence rate (IR) of myocardial infarction (MI), relative risk of MI, and impact of incident MI on mortality in individuals with biopsy-confirmed giant cell arteritis (GCA).
    Methods: MIs in individuals diagnosed with GCA 1998-2016 in Skåne, Sweden were identified by searching the SWEDEHEART register, a record of all patients receiving care for MI in a coronary care unit (CCU). The regional diagnosis database, with subsequent case review, identified GCA patients receiving care for MI outside of a CCU. A cohort of 10 reference subjects for each GCA case, matched for age, sex and area of residence, was used to calculate the incidence rate ratio (IRR) of MI in GCA to that in the general population.
    Results: The GCA cohort comprised 1134 individuals. During 7958 person-years of follow-up, 102 were diagnosed with incident MI, yielding an IR of 12.8 per 1000 person-years (95% CI 10.3 to 15.3). The IR was highest in the 30 days following GCA diagnosis and declined thereafter. The IRR of MI in GCA to that of the background population was 1.29 (95% CI 1.05 to 1.59). Mortality was higher in GCA patients who experienced incident MI than in those without MI (HR 2.8; 95% CI 2.2 to 3.6).
    Conclusions: The highest incidence of MI occurs within the 30 days following diagnosis of GCA. Individuals with GCA have a moderately increased risk of MI compared with a reference population. Incident MI has a major impact on mortality in GCA.

    Abstract Objective: Relapses of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis are important events that can cause organ dysfunction and reduce quality of life. Understanding the effects of the initial treatments for ANCA-associated vasculitis on the subsequent risk of relapse may help guide monitoring and treatment.
    Methods: We performed a post hoc analysis of participants with severe ANCA-associated vasculitis enrolled in an international two-by-two factorial randomized controlled trial comparing the effects of plasma exchange (PLEX) to no PLEX and a regimen of reduced glucocorticoid exposure to a standard regimen. We estimated the effects of treatments on relapses of any severity using three competing risk time-to-event models adjusted for patient and disease characteristics and other treatments. Each model was adjusted for disease manifestations in different ways.
    Results: Of 704 participants, 649 (92.2%) achieved remission and 147 (22.7%) experienced 204 relapses. The relapse rate was 10.3 (95% confidence interval [CI] 8.4-12.1) relapses per 100 patient-years. Neither the use of PLEX (subhazard ratio 0.91-0.94; 95% CIs range from 0.66 to 1.31) nor a glucocorticoid regimen (subhazard ratio 0.93-0.94; 95% CIs range from 0.67 to 1.35) appreciably changed the risk of relapse. Proteinase 3-ANCA and the presence of nonhemorrhagic respiratory manifestations of the disease at trial entry were associated with increased risks of relapse. Receiving dialysis at baseline and administration of oral cyclophosphamide as induction therapy were associated with lower risks of relapse.
    Conclusion: In patients with severe ANCA-associated vasculitis, relapses remain common; neither the use of PLEX nor an initial glucocorticoid tapering regimen impacted relapse risk.

    Abstract Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is characterised by inflammation and destruction of small to medium sized blood vessels. In the previously reported ADVOCATE study, a phase 3 double-blind, double-dummy randomised controlled trial of patients with newly diagnosed or relapsing ANCA-associated vasculitis, the oral selective complement 5a receptor inhibitor avacopan was shown to be non-inferior with regard to remission induction at week 26 and superior with regard to sustained remission at week 52, compared with a prednisone taper in a standard of care regimen. In this Article, we report an in-depth analysis of prespecified and exploratory patient-reported outcomes from the ADVOCATE study, measuring health-related quality of life and health utilities.
    Methods: We did a post-hoc analysis of patient-reported outcome data from the ADVOCATE study (NCT02994927) of patients with newly diagnosed or relapsing ANCA-associated vasculitis. We analysed summary scores and individual domain scores for the prespecified health-related quality of life outcomes from ADVOCATE, which were evaluated at weeks 26 and 52 by use of the Medical Outcomes Survey 36-Item Short Form Health Survey (SF-36) version 2, the EuroQol 5-Dimensions 5-Levels Questionnaire (EQ-5D-5L), and the EQ-5D health utility measure, assessed in the modified intention-to-treat population. We also calculated the Short Form 6 Dimension (SF-6D) score as an additional health utility measure. We evaluated the proportion of patients who reported scores that met or exceeded minimum clinically important differences in health-related quality of life, and we compared scores to normative values (age-specific and sex-specific scores from healthy populations from the USA matched to the protocol population). We also evaluated the proportion of patients who reported scores that met or exceeded minimum important difference in health utility scores.
    Findings: 331 patients were enrolled in the ADVOCATE trial, of whom 166 were in the avacopan group and 165 were in the prednisone standard of care group. In the avacopan group, the mean age was 61·2 years (SD 14·6), 98 (59%) of 166 patients were men, 68 (41%) were women, and 138 (83%) were White; in the prednisone group, the mean age was 60·5 years (14·5), 88 (54%) of 164 patients were men, 76 (46%) were women, and 140 (85%) were White. Patients treated with avacopan received approximately 2500 mg less median total prednisone up to week 52. Least squares means difference from baseline in physical component summary scores were significantly greater in patients in the avacopan group compared with those in the prednisone group at weeks 26 and 52, as well as in five of eight SF-36 domains at week 26 and two of eight SF-36 domains at week 52. The proportion of patients reporting scores equal to or greater than normative values was higher in the avacopan group than in the prednisone group across all SF-36 domains at both week 26 and 52, although the differences were not statistically significant with the exception of the role physical and vitality domains at week 26. Least squares means change from baseline in EQ-5D-5L visual analogue scale, EQ-5D health utility scores, and SF-6D health utility scores were significantly greater at week 52 in the avacopan group compared with the prednisone group.
    Interpretation: Patients with ANCA-associated vasculitis who received avacopan reported statistically significant and clinically meaningful improvements in health-related quality of life at 26 and 52 weeks and in health utility EQ-5D and SF-6D scores at 52 weeks. These patient-reported outcomes complement investigator assessments and support the efficacy of avacopan in patients with ANCA-associated vasculitis with use of lower prednisone doses.
