Popis: BackgroundLarge-vessel vasculitis are characterized by the wall inflammation of the involved vessels, which can be detected by imaging tools (1-3). Ultrasound (US) is one of the most commonly used tools for the diagnosis of giant cell arteritis (GCA), especially in patients with a cranial phenotype. Tocilizumab (TCZ) has shown efficacy in large-vessel vasculitis (LVV) including GCA (4,5). However, the improvement objectified by imaging techniques such as US after TCZ therapy is poorly documented.ObjectivesTo assess the effectiveness of TCZ improving the wall vessel inflammation by US.MethodsObservational, multicenter study of 26 GCA patients treated with TCZ. GCA was diagnosed according to: a) ACR criteria, and/or b) biopsy of temporal artery, and/or c) presence of signs of vessel wall inflammation by US, defined by the presence of halo sign. In all the cases a baseline US and in the follow-up was mandatory.Patients were divided into two subgroups: a) with, and b) without signs of improvement (partial or total) in the follow-up US.ResultsWe studied 26 patients (19 women/7 men; mean age, 76.3±9.7 years). Main clinical features of GCA with and without US improvement are shown in Table 1. We found no significant differences in any of the variables studied between the two groups.Table 1.Main features of 27 GCA patients treated with tocilizumab followed by Ultrasound (US).With US improvement (n=21)Without US improvement (n=5)pBaseline characteristics at TCZ onsetGeneral characteristicsAge(years), mean±SD77.3±8.972.2±12.90.270Sex, female/male (% female)17/4 (80,95)2/3 (40)0.101Time from GCA diagnosis to TCZ onset (months), median [IQR]6 [3-9]3 [1-6]0.452Systemic manifestations, n (%)Fever, n (%)1/21 (4.76)1/5 (20)0.354Constitutional syndrome, n (%)10/21 (47.62)2/5 (40)0.999PmR, n (%)11/21 (52.38)1/5 (20)0.330Ischaemic manifestations, n (%)Visual involvement, n (%)1/21 (4.76)1/5 (20)0.354Headache, n (%)15/21 (71.43)5/5 (100)0.298Jaw claudication, n (%)4/15 (26.67)¼ (25)0.999Laboratory dataESR, mm 1st hour, median [IQR]33 [22-49]55 [54-80]0.216CRP, mg/dL, median [IQR]1.5 [0.7-6.7]3.8 [1-4.2]0.948Prednisone dose, mg/day, median [IQR]13.7 [10-30]30 [12.5-30]0.505Time from TCZ onset and follow-up US (months)3.9±3.63.1±2.10.456After TCZ onset, 21 of 26 patients (80.7%) showed US signs of improvement (12 complete, 9 partial). In 4 out of 5 patients in whom there was no improvement in US findings, clinical improvement was observed at first month after starting TCZ.ConclusionTCZ seems to be effective controlling GCA including vascular involvement detected by US. This improvement can be seen by follow-up US, especially when performed at least 3 months after TCZ onset.References[1]Loricera J, et al. Rev Esp Med Nucl Imagen Mol. 2015; 34: 372-7.
