Tocilizumab in cranial and extracranial giant cell arteritis: a national multicenter study of 471 cases.

Objective: The spectrum of giant cell arteritis (GCA) includes different vascular phenotypes. Tocilizumab (TCZ) is the only biologic currently approved regardless these phenotypes. We aimed to assess the effectiveness of TCZ in different phenotypes.

Sustained Drug-Free Remission in Giant Cell Arteritis.

Objetive: To evaluate the frequency and timing of sustained drug-free remission (SDFR) in patients with giant cell arteritis (GCA) and to identify potential predictive factors of this outcome.

Methods: Retrospective review of all patients included in the large Spanish multicentre registry for GCA (ARTESER) with at least two years of follow-up. SDFR was defined as the absence of typical signs, symptoms, or other features of active GCA for ≥12 months after discontinuation of treatment.

18F-FDG-PET/CT Scan for Detection of Large Vessel Involvement in Giant Cell Arteritis: Arteser Spanish Registry.

Imaging studies have transformed the diagnosis of large vessel vasculitis (LVV) involvement in giant cell arteritis (GCA). A positron emission tomography/computed tomography (PET/CT) scan with 18-fluorodeoxyglucose (18F-FDG) has emerged as a valuable tool for assessing LVV. We aimed to determine the utility of an 18F-FDG-PET/CT scan in detecting LVV in GCA in the ARTESER registry.

Subcutaneous vs intravenous abatacept in rheumatoid arthritis-interstitial lung disease. National multicentre study of 397 patients.

Background: Evidence on abatacept (ABA) utility for rheumatoid arthritis (RA) - associated interstitial lung disease (ILD) is growing. Clinical trials have shown equivalence in subcutaneous (SC) and intravenous (IV) administration of ABA for articular manifestations. However, this has not been studied in respiratory outcomes.
