Title: Vasculitis Poster III: Immunosuppressive Therapy in Giant Cell Arteritis and Polymyalgia Rheumatica
Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: Giant cell arteritis (GCA) is a large vessel vasculitis with a predisposition for the cranial branches of the external carotid artery. However, aorta and / or its main branches may also be involved (1-4). In a series of patients with GCA who presented extracranial vessel involvement, our aim was to assess a) the vascular territories most frequently affected and b) correlation of a major extension of extracranial vascular involvement with a more severe clinical and analytical features.
Methods: Multicenter study of 68 patients with GCA who presented a compromise of extracranial vessels confirmed by PET/CT. Visual analysis of vascular uptake was performed on supra-aortic trunks (SAT), aortic arch (AA), thoracic aorta (TA), abdominal aorta (AA), iliac arteries (IA), lower limb arteries (LLA), and upper limb arteries (ULA).
Results: We evaluated 68 patients with GCA (51w/17m) with a mean age of 68.0±8.3 years. The vascular territories affected were: TA (n=58, 85.29%), SAT (n=38, 55.88%), AA (n=28, 41.18%), AA (n=18, 26.47%), LLA (n=17, 25%), IA (n=13, 19.12%) and ULA (n=6, 8.82%). We considered 3 groups according to the number of vascular territories affected: a) 1 or 2 territories, b) 3 or 4 territories and c) 5 or more territories and made a comparative study between this groups. In patients with ³5 vascular territories affected, we observed a higher baseline ESR, and the most frequent systemic manifestations were polymyalgia rheumatica and constitutional symptoms with statistical significance (TABLE). Distribution of categorical variables was compared by the Pearson Chi-squared test. Quantitative variables were analyzed using the ANOVA test.
Conclusion: In patients with GCA the involvement of TA is very frequent, followed by the SAT and the AA. Regarding the laboratory findings, patients with higher levels of ESR presented a major extension of extracranial vascular involment, as well as presenting PMR and/or constitutional symptoms was also related to more affection of extracranial territories.
