Arterial lesions in giant cell arteritis: A longitudinal study.

OBJECTIVES: To evaluate large-vessel (LV) abnormalities on serial imaging in patients with giant cell arteritis (GCA) and discern predictors of new lesions. METHODS: Clinical and imaging data from patients with GCA (including subjects diagnosed by LV imaging) enrolled in a prospective, multicenter, longitudinal study and/or a randomized clinical trial were included. New arterial lesions were defined as a lesion in a previously unaffected artery. RESULTS: The study included 187 patients with GCA, 146 (78%) female, mean (±SD) age at diagnosis 68.5 ± 8.5 years; 39% diagnosed by LV imaging. At least one arterial lesion was present in 123 (66%) on the first study. The most frequently affected arteries were subclavian (42%), axillary (32%), and thoracic aorta (20%). In 106 patients (57%) with serial imaging, new arterial lesions were noted in 41 patients (39%), all of whom had a baseline abnormality, over a mean (±SD) follow-up of 4.39 (2.22) years. New abnormalities were observed in 33% patients by year 2; clinical features of active disease were present at only 50% of these cases. There were no differences in age, sex, temporal artery biopsy positivity, or disease activity in patients with or without new lesions. CONCLUSIONS: In this cohort of patients with GCA, LV abnormalities on first imaging were common. Development of new arterial lesions occurred in patients with arterial abnormalities at first imaging, often in the absence of symptoms of active disease. Arterial imaging should be considered in all patients with GCA at diagnosis and serial imaging at least in patients with baseline abnormalities.

Impact of vasculitis on employment and income.

OBJECTIVES: Work disability associated with rheumatic diseases accounts for a substantial financial burden. However, few studies have investigated disability among patients with vasculitis. The purpose of this study was to examine the impact of vasculitis on patient employment and income. METHODS: Patients enrolled in the Vasculitis Clinical Research Consortium (VCRC) Patient Contact Registry, living in the USA or Canada, and followed for >1 year post-diagnosis, participated in an online survey-based study. RESULTS: 421 patients with different systemic vasculitides completed the survey between June and December 2015. The majority of patients were female (70%) and Caucasian (90%); granulomatosis with polyangiitis (GPA) was the most common type of vasculitis (49%), and the mean age at the time of diagnosis was 53 years. At the time of their diagnosis of vasculitis 76% of patients were working a paid job, 6% were retired, and 2% were on disability. Over the course of their disease, and with a mean follow-up of 8±6.4 years post-diagnosis, 26% of participants became permanently work disabled or had to retire early due to vasculitis. Variables that were independently associated with permanent work disability included work physicality, less supportive work environment, and symptoms such as respiratory disease, pain, and cognitive impairment. Overall, patients reported a mean productivity loss of 6.9% and income was reduced by a median of 45%. CONCLUSIONS: Due to their vasculitis, patients frequently suffer substantial limitations in work and productivity, and personal income loss.

Experience With Direct-to-Patient Recruitment for Enrollment Into a Clinical Trial in a Rare Disease: A Web-Based Study.

BACKGROUND: The target sample size for clinical trials often necessitates a multicenter (center of excellence, CoE) approach with associated added complexity, cost, and regulatory requirements. Alternative recruitment strategies need to be tested against this standard model. OBJECTIVES: The aim of our study was to test whether a Web-based direct recruitment approach (patient-centric, PC) using social marketing strategies provides a viable option to the CoE recruitment method. METHODS: PC recruitment and Web-based informed consent was compared with CoE recruitment for a randomized controlled trial (RCT) of continuing versus stopping low-dose prednisone for maintenance of remission of patients with granulomatosis with polyangiitis (GPA). RESULTS: The PC approach was not as successful as the CoE approach. Enrollment of those confirmed eligible by their physician was 10 of 13 (77%) and 49 of 51 (96%) in the PC and CoE arms, respectively (P=.05). The two approaches were not significantly different in terms of eligibility with 34% of potential participants in the CoE found to be ineligible as compared with 22% in the PC arm (P=.11) nor in provider acceptance, 22% versus 26% (P=.78). There was no difference in the understanding of the trial as reflected in the knowledge surveys of individuals in the PC and CoE arms. CONCLUSIONS: PC recruitment was substantially less successful than that achieved by the CoE approach. However, the PC approach was good at confirming eligibility and was as acceptable to providers and as understandable to patients as the CoE approach. The PC approach should be evaluated in other clinical settings to get a better sense of its potential.
