Giant cell arteritis (GCA) is a systemic inflammatory vasculitis affecting medium and large vessels with potentially sight and life-threatening complications. Early diagnosis and prompt treatment are imperative in order to prevent vision loss and progression of the disease. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are inflammatory markers which are elevated in the majority of patients and support the diagnosis of GCA among patients who present with typical symptoms. GCA is confirmed with superficial temporal artery biopsy which demonstrates characteristic pathological findings...

OBJECTIVES: To assess the long-term continuation of MTX in a cohort of patients with GCA in daily clinical practice. Factors associated with its discontinuation rate were also investigated. METHODS: A longitudinal study from 1991-2014, was performed. GCA patients with MTX and followed-up in a rheumatology outpatient clinic of Madrid during the study period were included. PRIMARY OUTCOME: discontinuation of MTX due to: adverse drug reaction (ADR moderate and severe); inefficacy; sustained clinical response; patient decision...

OBJECTIVE: To compare the efficacy of abatacept to placebo for giant cell arteritis (GCA). METHODS: In this multicenter trial, patients with newly-diagnosed or relapsing GCA were treated with abatacept 10 mg/kg IV on days 1, 15, 29, week 8, together with prednisone. At week 12, patients in remission underwent a double-blinded randomization to continue monthly abatacept or switch to placebo. Patients in both study arms received a standardized prednisone taper with discontinuation of prednisone at week 28...

Giant cell arteritis and Takayasu arteritis are the two major forms of idiopathic large vessel vasculitis. High doses of glucocorticoids are effective in inducing remission in both conditions, but relapses and recurrences are common, requiring prolonged glucocorticoid treatment with the risk of the related adverse events. Areas covered: In this article, we will review the standard and biological treatment strategies in large vessel vasculitis, and we will focus on the current approaches to these diseases. Expert commentary: The results of treatment trials with conventional immunosuppressive agents such as methotrexate, azathioprine, mycophenolate mofetil, and cyclophosphamide have overall been disappointing...

Giant cell arteritis (GCA) causes autoimmune inflammation of the aorta and its large branches, resulting in aortic arch syndrome, blindness, and stroke. CD4(+) T cells and macrophages form organized granulomatous lesions in the walls of affected arteries, destroy the tunica media, and induce ischemic organ damage through rapid intimal hyperplasia and luminal occlusion. Pathogenic mechanisms remain insufficiently understood; specifically, it is unknown whether the unopposed activation of the immune system is because of deficiency of immunoinhibitory checkpoints...

BACKGROUND: To evaluate the relative frequencies of arteritic and nonarteritic anterior ischemic optic neuropathy (AION) in an Arab population and to compare and contrast these findings with known epidemiological data from Caucasian populations. METHODS: A retrospective review of the medical records of all patients diagnosed with AION at the King Khaled Eye Specialist Hospital (KKESH) in Riyadh, Saudi Arabia, between 1997 and 2012. RESULTS: Of 171 patients with AION, 4 had biopsy-proven giant-cell arteritis (GCA)...

OBJECTIVE: Our aim was to describe patients with giant cell arteritis (GCA)-related stroke and to compare them with a control group of GCA patients without stroke. METHODS: We created a retrospective multicenter cohort of patients with (1) GCA diagnosed according to the American College of Rheumatology criteria between 1995 and 2015, and (2) stroke occurring at the time of GCA diagnosis or occurring within 4 weeks of starting GCA therapy. The control group consisted of GCA patients without stroke...

OBJECTIVE: To evaluate the associations between GCA and vascular diseases and other comorbidities in patients with GCA compared with non-vasculitis patients. METHODS: Using the UK-based Clinical Practice Research Datalink we identified 9778 newly diagnosed GCA patients in 1990-2014, and up to 10 non-vasculitis patients randomly matched to each case on age, sex, practice and years of history before cohort entry. We compared the distributions of 9 different pre-existing vascular diseases and 11 other comorbidities, and risks of incident vascular diseases and other comorbidities after cohort entry between GCA and non-vasculitis patients...

Giant cell arteritis is one of the most frequent causes of pyrexia of unknown origin after infectious or malignant causes have been ruled out. In this case report we describe a 66-year old female patient, who after five weeks of remitting fever developed a life-threatening, painless severe aortic dissection. The timely use of modern imaging technologies such as magnetic resonance angiography or positron emission computed tomography could in the future be of help to recognize aortic involvement early and to avoid this devastating complication in patients with fever of unknown origin...

Giant cell arteritis and Takayasu arteritis classified to large vessel vasculitides have similar histopathology in the vascular wall proposing that these entities can be different phenotypes on a spectrum of a single disorder. Glucocorticoids are the mainstay of therapy combined with cyclophosphamide, azatioprine and mycofenolate mofetil, when it is required. However, a significant proportion of patients are glucocorticoid-dependent despite of the conventional disease-modifying antirheumatic drugs and suffer from serious side effects of the steroids, therefore alternate options for more effective disease management are needed...

OBJECTIVES: Autoantibodies are useful biomarkers for diagnosing and monitoring treatment in some autoimmune diseases. Antibodies against isoforms of 14-3-3 protein have been proposed as biomarkers for the presence of aortic aneurysm in large-vessel vasculitis (LVV). Here, we aimed to evaluate the diagnostic role and potential immunopathological involvement of anti-14-3-3 antibodies in newly diagnosed LVV patients. METHODS: Antibodies against three isoforms of 14-3-3 (γ, ε and ζ) were measured in 90 subjects: 48 GCA and 3 Takayasu's arteritis (TA) patients, and 39 controls (non-inflammatory and inflammatory diseases), using a multiplexed bead-based immunoassay and immunoprecipitation studies...

Giant cell arteritis (GCA) is the most common form of vasculitis in individuals older than 50 years in Western countries. To shed light onto the genetic background influencing susceptibility for GCA, we performed a genome-wide association screening in a well-powered study cohort. After imputation, 1,844,133 genetic variants were analyzed in 2,134 case subjects and 9,125 unaffected individuals from ten independent populations of European ancestry. Our data confirmed HLA class II as the strongest associated region (independent signals: rs9268905, p = 1...

BACKGROUND: Previous studies of mortality associated with GCA have shown conflicting results. We conducted a systematic review and meta-analysis to determine the mortality risk in GCA patients compared to the general population. METHODS: We searched for published studies indexed in MEDLINE and EMBASE and the Cochrane database from inception to June 18, 2015 using the terms "giant cell arteritis" and "temporal arteritis" combined with the terms for death, mortality, and survival...

OBJECTIVE: Giant cell arteritis (GCA) is an inflammatory vasculitis preferentially affecting large and medium-sized arteries. High-dose oral glucocorticoids (GCs) are the mainstay of GCA therapy. Using data from the UK Clinical Practice Research Datalink (CPRD), we examined the risk of oral GC-related serious adverse events (SAEs) in a UK population of patients with giant cell arteritis (GCA). METHODS: We conducted a series of nested case-control analyses in GCA patients to examine the effect of increasing dose of prednisolone on the risk of developing diabetes, glaucoma, osteoporosis, fractures, serious infection requiring hospitalization, and death...

Ischemic optic neuropathy (ION) describes a state of hypoxic injury of the optic nerve. Clinically, ION is divided into anterior and posterior forms defined by the presence or absence of optic disc swelling, respectively. It is further classified as arteritic when secondary to vasculitis, and nonarteritic when not. The site of vascular occlusion for anterior ION from giant cell arteritis is the short posterior ciliary arteries, but mechanical vascular obstruction does not play a role in most nonarteritic cases...
