ObjectivesLarge-vessel involvement (LVI) can occur in giant-cell arteritis (GCA) and may represent a distinct disease subgroup with a higher risk for aortic dilation. This study aimed to better characterize the presentation and evolution of LVI in patients with GCA.Patients and methodsA retrospective multicenter study enrolled 248 GCA patients with LVI and 301 GCA patients without LVI on imaging. Factors associated with aortic dilation were identified in a multivariable model.ResultsThe patients with LVI were younger (p<0.0001), more likely to be women (p=0.01), and showed fewer cephalic symptoms (p<0.0001) and polymyalgia rheumatica (p=0.001) but more extracranial vascular symptoms (p=0.05) than the patients without LVI. Glucocorticoids (GC) management did not differ between the two groups, but the GC discontinuation rate was lower in the patients with LVI (p=0.0003). Repeated aortic imaging procedures were performed at 19months [range: 5–162months] and 17months [range: 6–168months] after diagnosis in 154 patients with LVI and 123 patients without LVI, respectively, of whom 21% and 7%, respectively, presented new aortic dilations (p=0.0008). In the patients with LVI, aortic dilation occurred on an aorta segment shown to be inflammatory on previous imaging in 94% of patients. In the multivariate analysis, LVI was the strongest predictor of aortic dilation (hazard ratio: 3.16 [range: 1.34–7.48], p=0.009).ConclusionsLVI represents a distinct disease pattern of GCA with an increased risk of aortic dilation. Control of the aortic morphology during follow-up is required.
