ObjectivesTo determine the prevalence of cerebrovascular events (CVE) in giant cell arteritis (GCA) and to alert clinicians to the importance of early detection of CVE in this disease.MethodsRetrospective observational study involving a cohort of GCA patients. Demographic, clinical and laboratory data were collected. All patients fulfilled the American College of Rheumatology (ACR) 1990 GCA classification criteria and had a positive ultrasound test for GCA in agreement with the EULAR recommendations. Demographic and clinical parameters were recorded with special attention paid to ischemic cranial events.ResultsWe studied 123 consecutive GCA patients, 74 (60.2%) women with a mean age of 79 years. Twelve patients (9.75%) suffered from neurologic symptoms other than AION, of whom 9 (7.3%) experienced ischemic events related to GCA and 3 (2.44%) likely experienced CVE due to other common causes. Of the 9 patients with CVE caused by GCA, 5 were diagnosed with transient ischemic attacks (TIAs), 2 with ischemic stroke, and 2 were cases involving cranial nerve palsies. High rates of mortality were found in patients with a TIA or stroke, while polymyalgia rheumatica (PMR) appeared to confer some protection against ischemic pathologies in GCA patients.ConclusionsStroke and TIA are common presentation patterns associated with GCA and should be suspected in all CVE-related cases with high acute-phase reactants commonly present in the elderly. This ischemic subgroup exhibited a higher mortality rate.Copyright © 2020 Elsevier España, S.L.U. All rights reserved.
