Objectives: To evaluate differences in presentation and outcome of giant cell arteritis (GCA) patients with and without polymyalgia rheumatica (PMR) symptoms.
Methods: Consecutive patients diagnosed with GCA between 2000 and 2020 and followed for ≥12 months at the University Hospitals Leuven (Belgium), were included retrospectively.
Results: We included 398 GCA patients, of which 181 (45%) with PMR symptoms.
Background: Giant cell arteritis is an age-related vasculitis that mainly affects the aorta and its branches in individuals aged 50 years and older. Current options for diagnosis and treatment are scarce, highlighting the need to better understand its underlying pathogenesis. Genome-wide association studies (GWAS) have emerged as a powerful tool for unravelling the pathogenic mechanisms involved in complex diseases.
