Assessing Biomarker in Giant Cell Arteritis and Polymyalgia Rheumatic

The GCAIO study is an innovative, multimodal research initiative designed to enhance the understanding, diagnosis, and management of giant cell arteritis (GCA) and frequently associated polymyalgia rheumatica (PMR). This longitudinal study aims to dissect the complex immunological landscape and systemic manifestations of these conditions through a combination of diagnostic imaging and detailed immunological profiling. The study focuses on three primary objectives: (1) Identifying and analyzing cytokine profiles and immune cell phenotypes, employing techniques like flow cytometry, enzyme-linked immunosorbent assays (ELISA), and next-generation sequencing to predict disease activity and therapeutic responses. (2) Advancing diagnostic and monitoring capabilities through the application of novel and established imaging technologies, including MRI, optical coherence tomography angiography (OCTA), and ultrasound. These modalities aim to improve the detection of neuro-ophthalmological, cardiac, and aortic complications in GCA, potentially offering more precise monitoring and earlier diagnosis. (3) Enhancing the understanding of PMR within the context of GCA by exploring specific biomarkers and advanced imaging to refine diagnostic accuracy and treatment strategies, thus improving patient outcomes.
