Microvascular networks in the adventitia of large arteries control access of inflammatory cells to the inner wall layers (media and intima) and thus protect the immune privilege of the aorta and its major branches. In autoimmune vasculitis giant cell arteritis (GCA), CD4 T helper 1 (TH1) and TH17 cells invade into the wall of the aorta and large elastic arteries to form tissue-destructive granulomas. Whether the disease microenvironment provides instructive cues for vasculitogenic T cells is unknown. We report that adventitial microvascular endothelial cells (mvECs) perform immunoregulatory functions by up-regulating the expression of the Notch ligand Jagged1...

Large vessels vasculitis includes two diseases : 1) giant cell arteritis, formerly known as Horton's arteritis and 2) Takayasu arteritis. In this article, we will describe and compare the epidemiology, pathogenesis, diagnostic criteria and medical management of both vasculitis. T helper (Th) 1 and Th17 responses, genetic links and the role of viral (varicella zoster) and bacterial infection (Mycoplasma pneumoniae or Chlamydia pneumoniae) will be discussed. Classification criteria, inflammation biomarkers and progress in imaging tools will also be described...

We present a case of supraclinoid internal carotid artery dissection. Eleven months prior, the patient developed isolated periorbital pain and was diagnosed with giant-cell arteritis with iritis. The patient experienced recurrent spells concerning for transient ischaemic attacks and was transferred to our institution for endovascular intervention after head CT revealed an embolic infarct with a 'dense middle cerebral artery sign.' Digital subtraction angiography was negative for occlusion, instead demonstrating luminal stenosis and poststenotic dilatation...

Non-infectious aortitis is usually due to giant-cell arteritis, Takayasu disease or Behçet disease. The main aortic lesions are stenoses, occlusions and aneurysms in the Takayasu disease and aneurysms in the Behçet disease and giant-cell arteritis. Treatment is based on corticosteroid therapy and surgery. Endoluminal management is now the rule. We report a retrospective descriptive study of 10 patients who underwent surgical or endoluminal management of inflammatory lesions of the aorta between January 2000 and December 2015...

If there is no pain in the temporal artery, the diagnosis of giant cell arteritis (GCA) may be delayed and blindness may occur. Therefore, FDG-PET/CT is important as a modality for diagnosis of GCA. When GCA is suspected and F-18 FDG-PET/CT is performed, it is worthwhile to pay attention to shoulder and hip joints as polymyalgia rheumatica commonly presents with GCA.

Giant cell arteritis (GCA) is the most common form of vasculitis in individuals aged 50 years and over. GCA typically affects large and medium-sized arteries, with a predilection for the extracranial branches of the carotid artery. Patients with GCA usually present with symptoms and signs that are directly related to the artery that is affected, with or without constitutional manifestations. The most dreaded complication of GCA is visual loss, which affects about one in six patients and is typically caused by arteritis of the ophthalmic branches of the internal carotid artery...

BACKGROUND/OBJECTIVE: It has been reported that CD40 rs1883832 might be associated with immune-related diseases susceptibility. Owing to mixed and inconclusive results, we conducted a meta-analysis of case-control studies to summarize and clarify this association.Methods/main results: A systematic search of studies on the association between CD40 rs1883832 and immune-related diseases susceptibility was conducted in databases. Odds ratios and 95% confidence intervals were used to pool the effect size...

Temporal artery biopsy is the gold standard investigation for the diagnosis of giant cell arteritis. The aim of this retrospective study was to investigate the use of temporal artery biopsy in diagnosing giant cell arteritis in south-east Scotland over a five-year period. We aimed to quantify success rates, and predictive factors for a positive biopsy, as well as compare the different specialities performing the biopsies. The data should enable the development of better criteria for referral for investigation of giant cell arteritis...

BACKGROUND: Early temporal artery biopsy is recommended in all patients with suspected cranial GCA (Giant Cell Arteritis) by the BSR (British Society of Rheumatology) and BHPR (British Health Professionals in Rheumatology) guidelines. This should be performed within one week ideally. AIM: To assess ACR (American College of Rheumatology) score at presentation and whether temporal artery biopsy result affects clinical management of the clinically suspected GCA patient...

INTRODUCTION: Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are common inflammatory conditions. The diagnosis of PMR/GCA poses many challenges since there are no specific diagnostic tests. Recent literature emphasizes the ability of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) to assess global disease activity in inflammatory diseases. 18F-FDG PET/CT may lead to the diagnosis at an earlier stage than conventional imaging and may also assess response to therapy...

BACKGROUND: Giant cell arteritis (GCA), if untreated, can lead to blindness and stroke. The study's objectives were to (1) determine a new evidence-based benchmark of the extent of diagnostic delay for GCA and (2) examine the role of GCA-specific characteristics on diagnostic delay. METHODS: Medical literature databases were searched from inception to November 2015. Articles were included if reporting a time-period of diagnostic delay between onset of GCA symptoms and diagnosis...

Polymyalgia rheumatica (PMR) is an inflammatory disease characterized by aching and stiffness in the girdles, which affects typically people over 50 years old and could overlap with giant cell arteritis (GCA) in about 15-20% of cases. Although the diagnosis of PMR is usually considered straightforward, clinicians facing this disease should be aware of its atypical manifestations, which can hamper the correct identification of PMR and, conversely, should be aware of other diseases which may present with polymyalgic features...

According to the Chapel Hill Classification, large vessel vasculitides encompass giant cell arteritis (GCA) and the histologically related Takakaysu arteritis (TAK). The two diseases lack autoantibodies and present with a systemic inflammatory response. GCA typically shows a sudden onset with profound sickness, loss of appetite and of body weight, and temporal headache. Due to the substantial risk of sudden blindness, diagnostic work-up has to be performed immediately and treatment started without delay. A close association between polymyalgia rheumatica (PMR) and GCA is well established...

OBJECTIVE: To report two patients with giant cell arteritis (GCA) who developed rheumatoid arthritis (RA) and to review the literature in terms of coexistence of RA, GCA, and polymyalgia rheumatica (PMR). METHODS: We conducted a comprehensive review of the English literature from 1980 to 2015 to analyze data on the coexistence of GCA and RA. The PubMed, Web of Science, Proquest, and Ovid databases were searched for articles using the term RA combined with temporal arteritis, GCA, and PMR...

Aortitis is a broad term describing inflammation of the aorta. The most common causes of aortitis are the large-vessel vasculitides giant cell arteritis and Takayasu arteritis. Other etiologies include aortitis associated with other autoimmune disorders, infectious causes, and paraneoplastic and idiopathic cases. We describe a rare case of a large-vessel arteritis occurring in association with chronic myelomonocytic leukemia (CMML). A 68-year-old female with recent diagnosis of CMML presented to our office for evaluation of abnormal chest computed tomography (CT) that showed inflammation surrounding the entirety of thoracic and abdominal aorta, consistent with aortitis...
