Abstract
OBJECTIVES To review the literature in order to estimate how many previously unknown thoracic aortic aneurysms (TAAs) and thoracic aortic dilatations (TADs) might be detected by systematic, cross-sectional aortic imaging of patients with giant cell arteritis (GCA). METHODS A systematic literature review was performed using Ovid Medline, Embase and the Cochrane Library. Studies potentially relevant to TAA/TAD were evaluated by two authors independently for relevance, bias and heterogeneity. Meta-analysis was performed using a random-effects model to estimate pooled prevalence. RESULTS Two analyses of routinely collected administrative data suggested a threefold risk of TAA/dissection in GCA compared with controls. In GCA cohorts without systematic imaging, 2-8% had TAA. In the two best-reported studies, aneurysm dissection/rupture occurred in 1% and 6% of GCA cases. Aortic imaging studies had a variety of TAA/TAD definitions, imaging methods and time points. There were limited data on age-matched controls. Three studies suggested that male sex may be a risk factor for TAA/TAD in GCA. On average, five to ten patients with GCA would need aortic imaging to detect one previously unknown TAA/TAD. CONCLUSIONS The data support an association between GCA and TAA/TAD compared with age-matched controls, but the true relative risk, and the time course of that risk, remains unclear. It is also unclear whether chest radiography is a sufficiently sensitive screening tool. Clinicians should retain a high index of suspicion for aortic pathology in patients with GCA. Before ordering imaging, clinicians should consider whether, and how, detecting aortic pathology would affect a patient's management.

Abstract
OBJECTIVES To evaluate incidence-trends and timing of large-vessel (LV) manifestations in patients with giant cell arteritis (GCA), and to examine the influence of LV manifestations on survival. METHODS A population-based incident cohort of patients diagnosed with GCA between 1950 and 2004 was used. LV involvement was defined as large-artery stenosis or aortic aneurysm/dissection that developed in the 1 year before GCA diagnosis or at any time thereafter. Patients were followed up until death or 31 December 2009. RESULTS The study included 204 patients, 80% women, mean age at diagnosis of GCA 76.0 years (±8.2 years). Median length of follow-up was 8.8 years. The cumulative incidence of any LV manifestation at 10 years was 24.9% for patients diagnosed with GCA between 1980 and 2004 compared with 8.3% for patients diagnosed with GCA between 1950 and 1979. The incidence of any LV event was high within the first year of GCA diagnosis. The incidence of aortic aneurysm/dissection increased 5 years after GCA diagnosis. Compared with the general population, survival was decreased in patients with an aortic aneurysm/dissection (standardized mortality ratio (SMR) 2.63; 95% CI 1.78 to 3.73) but not in patients with large-artery stenosis (SMR 1.44; 95% CI 0.87 to 2.25). Patients with GCA and aortic manifestations had a higher than expected number of deaths from cardiovascular and pulmonary causes than the general population. Among patients with GCA, aortic manifestations were associated with increased mortality (HR=3.4; 95% CI 2.2 to 5.4). CONCLUSIONS Vigilance and screening for aortic aneurysms should be considered in all patients 5 years after the incidence of GCA. Aortic aneurysm/dissection is associated with increased mortality in GCA.

Abstract
Objective.Studies have shown that aortitis may be present in half the patients with recent-onset giant cell arteritis (GCA). We assessed whether aortitis at diagnosis affects longterm outcome in patients with GCA.Methods.We retrospectively analyzed the longterm outcome of a prospective cohort of 22 patients with biopsy-proven GCA who all had aortic computed tomography (CT) evaluation at the time of diagnosis of GCA between May 1998 and November 1999. Longterm outcome, especially vascular events such as aortic aneurysm, mortality, relapses of GCA, and requirement for steroids, was assessed in 2011 by chart review and patient/physician interviews.Results.At disease onset, 10/22 patients had aortitis on CT scan. Patients with and without aortitis had similar baseline characteristics, including cardiovascular risk profile. At the time of the study, 12/22 (57%) patients had died. Vascular causes of death were more frequent in patients with aortitis (5/7 vs 0/5; p = 0.02). A higher number of vascular events was noted in patients with aortitis (mean events per patient 1.33 vs 0.25; p = 0.009). Stroke was more frequent in patients with aortitis. These patients seemed to exhibit a more chronic or relapsing disease course, and they were less likely to completely discontinue steroid therapy (p = 0.009, log-rank test).Conclusion.Our study suggests for the first time that inflammatory aortic involvement present at onset of GCA could predict a more chronic/relapsing course of GCA, with higher steroid requirements and an increased risk for vascular events in the long term.

Abstract
Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are inflammatory diseases that typically affect white individuals >50 years. Women are affected ∼2-3 times more often than men. PMR and GCA occur together more frequently than expected by chance. The main symptoms of PMR are pain and stiffness in the shoulders, and often in the neck and pelvic girdle. Imaging studies reveal inflammation of joints and bursae of the affected areas. GCA is a large-vessel and medium-vessel arteritis predominantly involving the branches of the aortic arch. The typical clinical manifestations of GCA are new headache, jaw claudication and visual loss. PMR and GCA usually remit within 6 months to 2 years from disease onset. Some patients, however, have a relapsing course and might require long-standing treatment. Diagnosis of PMR and GCA is based on clinical features and elevated levels of inflammatory markers. Temporal artery biopsy remains the gold standard to support the diagnosis of GCA; imaging studies are useful to delineate large-vessel involvement in GCA. Glucocorticoids remain the cornerstone of treatment of both PMR and GCA, but patients with GCA require higher doses. Synthetic immunosuppressive drugs also have a role in disease management, whereas the role of biologic agents is currently unclear.

Abstract
Giant cell arteritis (GCA) is the most common form of large vessel arteritis. GCA typically involves the branches of the external carotid artery, but is the leading cause of inflammatory aortitis. However, involvement of the aorta often goes undetected. We present a case of an 81-year-old man, with headache and intense chest pain, who was previously given a diagnosis of GCA with a temporal artery biopsy 6 years ago. Owing to the suspicion of acute aortic syndrome, an emergent computed tomography (CT) was performed. CT showed the development of mega-aorta syndrome, with a diameter of 75.2 mm in the ascending aorta, 61.8 mm in the aortic arch, 76.1 mm in the descending thoracic aorta, and 45.1 mm in the abdominal aorta, presenting a chronic type B aortic dissection. Although there are reported cases secondary to Takayasu arteritis, this is the first case reported in the literature of mega-aorta syndrome associated with GCA in a patient previously diagnosed using temporal artery biopsy.

Abstract
OBJECTIVES To compare patterns of arteriographic lesions of the aorta and primary branches in patients with Takayasu's arteritis (TAK) and giant cell arteritis (GCA). METHODS Patients were selected from two North American cohorts of TAK and GCA. The frequency of arteriographic lesions was calculated for 15 large arteries. Cluster analysis was used to derive patterns of arterial disease in TAK versus GCA and in patients categorised by age at disease onset. Using latent class analysis, computer derived classification models based upon patterns of arterial disease were compared with traditional classification. RESULTS Arteriographic lesions were identified in 145 patients with TAK and 62 patients with GCA. Cluster analysis demonstrated that arterial involvement was contiguous in the aorta and usually symmetric in paired branch vessels for TAK and GCA. There was significantly more left carotid (p=0.03) and mesenteric (p=0.02) artery disease in TAK and more left and right axillary (p<0.01) artery disease in GCA. Subclavian disease clustered asymmetrically in TAK and in patients ≤55 years at disease onset and clustered symmetrically in GCA and patients >55 years at disease onset. Computer derived classification models distinguished TAK from GCA in two subgroups, defining 26% and 18% of the study sample; however, 56% of patients were classified into a subgroup that did not strongly differentiate between TAK and GCA. CONCLUSIONS Strong similarities and subtle differences in the distribution of arterial disease were observed between TAK and GCA. These findings suggest that TAK and GCA may exist on a spectrum within the same disease.

Abstract
OBJECTIVE To assess the utility of the vascular physical examination to detect arteriographic lesions in patients with established large vessel vasculitis (LVV), including Takayasu's arteritis (TAK) and giant cell arteritis (GCA). METHODS In total, 100 patients (TAK = 68, GCA = 32) underwent standardized physical examination and angiography of the carotid, subclavian, and axillary arteries. Sensitivity and specificity were calculated for the association between findings on physical examination focusing on the vascular system (absent pulse, bruit, and blood pressure difference) and arteriographic lesions defined as stenosis, occlusion, or aneurysm. RESULTS We found 67% of patients had at least 1 abnormality on physical examination (74% TAK, 53% GCA). Arteriographic lesions were seen in 76% of patients (82% TAK, 63% GCA). Individual physical examination findings had poor sensitivity (range 14%-50%) and good-excellent specificity (range 71%-98%) to detect arteriographic lesions. Even when considering physical examination findings in combination, at least 30% of arteriographic lesions were missed. Specificity improved (range 88%-100%) if individual physical examination findings were compared to a broader region of vessels rather than specific anatomically correlated vessels and if ≥ 1 physical examination findings were combined. CONCLUSION In patients with established LVV, physical examination alone is worthwhile to detect arterial disease but does not always localize or reveal the full extent of arteriographic lesions. Abnormal vascular system findings on physical examination are highly associated with the presence of arterial lesions, but normal findings on physical examination do not exclude the possibility of arterial disease. Serial angiographic assessment is advisable to monitor arterial disease in patients with established LVV.

Abstract
A 54-year-old white man with a remote history of pars planitis reported transient monocular visual loss (TMVL) in the left eye on standing. The following week he experienced multiple similar episodes. He denied associated systemic symptoms. Initial examination showed old peripheral retinal vascular sheathing and delayed retinal arterial filling time. Complete blood count, erythrocyte sedimentation rate, and MRI studies of the head and neck were normal. One week later, there were multiple cotton wool spots in the posterior pole, a relative afferent pupillary defect, and subtle visual field loss in the left eye. Evaluation for infectious, inflammatory, or embolic etiologies was nonrevealing. Biopsy of the prominent but nontender temporal arteries showed granulomatous inflammation, fragmentation, and duplication of the internal elastic lamina consistent with the temporal arteritis (TA). Radiography and MRI of the chest revealed dilation of the ascending aorta. The patient began treatment with high-dose oral steroids with resolution of his TMVL and retinal cotton wool spots and decrease in the size of the temporal arteries. Our case demonstrates the importance of considering TA in the setting of TMVL, visual loss, cotton wool spots, or dilated nontender temporal arteries in an otherwise asymptomatic patient even with normal inflammatory markers. Long-term follow-up is essential in unusual cases such as this one, given the high risk of ocular and systemic morbidity with TA.

Abstract
Both polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) present with a broad spectrum of clinical manifestations and almost exclusively occur in the population aged over 50 years. After rheumatoid arthritis, PMR is the second most common autoimmune rheumatic disorder. Visual loss is the most feared complication in temporal arteritis, and extracranial arteries and/or aorta are more often involved in GCA than previously estimated. No specific laboratory parameter exists for diagnosis of PMR. Imaging techniques such as ultrasonography, MRI or 18F-fluorodeoxyglucose PET may be helpful in the diagnosis and evaluation of the extent of vascular involvement in these diseases. This article highlights upcoming new classification criteria for PMR, recent advances of diagnostic and therapeutic procedures as well as ongoing research on biomarkers and corticosteroid-sparing medications, which should improve management of PMR and GCA.

Abstract
Giant cell (GCA) and Takayasu's arteritis (TAK) are 2 forms of large-vessel vasculitis (LVV) that involve the aorta and its major branches. GCA has a predilection for the cranial branches, while TAK tends to affect the extracranial branches. Both disorders may also cause nonspecific constitutional symptoms. Although some clinical features are more common in one or the other disorder and the ages of initial presentation differ substantially, there is enough clinical and histopathologic overlap between these disorders that some investigators suggest GCA and TAK may be 2 processes within the spectrum of a single disease. There have been few randomized therapeutic trials completed in GCA, and none in TAK. The lack of therapeutic trials in LVV is only partially explained by the rarity of these diseases. It is likely that the lack of well validated outcome measures for LVV and uncertainties regarding trial design contribute to the paucity of trials for these diseases. An initiative to develop a core set of outcome measures for use in clinical trials of LVV was launched by the international OMERACT Vasculitis Working Group in 2009 and subsequently endorsed by the OMERACT community at the OMERACT 10 meeting. Aims of this initiative include: (1) to review the literature and existing data related to outcome assessments in LVV; (2) to obtain the opinion of experts and patients on disease content; and (3) to formulate a research agenda to facilitate a more data-based approach to outcomes development.

Abstract
OBJECTIVE To assess the clinical relevance of increased circulating cytokines in patients with giant cell arteritis (GCA) after long-term followup. METHODS We performed a cross-sectional evaluation of 54 patients with biopsy-proven GCA prospectively followed for a median of 5.4 years (range 4-10.5 years). GCA-related complications, vascular events, relapses, current prednisone dose, time required to achieve a maintenance prednisone dosage <10 mg/day, cumulated prednisone at that point, and adverse effects during followup were recorded. Serum interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFalpha) were determined by immunoassay. RESULTS All patients were in clinical remission. Both cytokines were significantly higher in patients than in controls (mean +/- SD 21 +/- 35 versus 5 +/- 11 pg/ml; P < 0.001 for IL-6 and mean +/- SD 32 +/- 14 versus 16 +/- 9 pg/ml; P < 0.001 for TNFalpha). No differences were found in patients with or without GCA-related complications or vascular events during followup. Circulating cytokines were significantly higher in patients who had experienced relapses (mean +/- SD 25 +/- 39 versus 10 +/- 11 pg/ml; P = 0.04 for IL-6 and mean +/- SD 34 +/- 15 versus 25 +/- 11 pg/ml; P = 0.042 for TNFalpha). IL-6 was significantly higher in patients still requiring prednisone (mean +/- SD 29 +/- 45 versus 13 +/- 17 pg/ml; P = 0.008), and TNFalpha correlated with cumulated prednisone dose (r = 0.292, P = 0.04). No significant relationship was found between elevated cytokines and prednisone adverse effects or patients' quality of life. CONCLUSION Circulating TNFalpha and IL-6 may persist elevated in GCA patients after long-term followup and remain higher in patients who have experienced more relapsing disease. However, in this patient cohort, elevated circulating cytokines were not associated with increased frequency of GCA complications, vascular events, or treatment-related side effects.

Abstract
[18F]fluorodeoxyglucose positron emission tomography (PET) is a noninvasive metabolic imaging modality that is well-suited to the assessment of activity and extent of large vessel vasculitis. PET imaging has demonstrated its usefulness in diagnosing giant cell arteritis (notably in its silent form), Takayasu's arteritis, and unclassified aortitis. PET imaging could be more effective than magnetic resonance imaging in detecting the earliest stages of vascular wall inflammation. The visual grading of vascular [18F]FDG uptake makes it possible to discriminate arteritis from active atherosclerosis, providing therefore high specificity. High sensitivity can also be achieved provided scanning is performed during active inflammatory phase, preferably before starting corticosteroid treatment. Prospective studies are needed to determine the exact value of PET imaging in assessing other vasculitis subsets, infectious aortitis, and large vessel vasculitis outcome and response to immunosuppressive treatment.

Abstract
This article focuses on the clinical application and technical aspects of imaging methods which are used alternatively or additionally to angiography or magnetic resonance imaging in patients with Takayasu's arteritis or giant cell arteritis. Providing a high spatial resolution, duplex ultrasound is particularly suitable for the evaluation of peripheral arteries. With the exception of cranial arteries, positron emission tomography as a whole body examination is the best imaging modality for the assessment of inflammatory activity. Computed tomography is used for angiographic examinations and enables evaluation of wall thickening in large arteries. It is the method of choice in the case of emergencies due to aortic aneurysm or dissection. In addition to angiographic and ultrasound techniques, ophthalmological methods comprise biomicroscopy, including funduscopy and optical coherence tomography.

Abstract
Objective.To identify the clinical presentation and histopathologic characteristics of noninfectious ascending aortitis.Methods.A retrospective medical record and histopathology review was performed of patients with histologic evidence of active noninfectious aortitis who underwent ascending aortic aneurysm resection at Mayo Clinic between January 1, 2000, and February 28, 2006. Clinicopathologic features were recorded, including demographics, clinical presentation, laboratory, imaging findings, histopathology, complications, treatment, and outcome.Results.Sixty-four patients (50% women) were identified; the majority were Caucasian (83%) and elderly (mean age 69.1 yrs). Upon initial presentation, 45% had aneurysm-related symptoms, 33% were asymptomatic, 12.5% had constitutional symptoms, 4.7% had symptoms referable to cranial arteries, and 9.4% had polymyalgia rheumatica (PMR) symptoms. The majority (81%) were of “isolated” variant, with no rheumatologic history. Mean preoperative erythrocyte sedimentation rate was 16.2 ± 23.3 mm/h (n = 20). Additional vascular imaging abnormalities were present in 72% of patients, including stenoses and/or ectasia of major aortic branches and descending thoracic or abdominal aneurysms. Giant cells were seen in 71.9%. Median followup time was 15.4 months, during which 6 (9.4%) patients died. Only 22 (34%) patients received corticosteroids, with uncertain effect on development of recurrent aneurysms, rupture, or dissections.Conclusion.Noninfectious ascending aortitis frequently occurs even in the absence of history, symptoms, or signs of giant cell arteritis (GCA) or PMR. When discovered, such patients should be followed closely, as a majority have additional vascular abnormalities. More studies are needed to determine optimal strategies for surveillance, detection, and treatment of ascending aortitis, which may represent a clinical entity distinct from classical GCA.

Abstract
Myalgias most commonly occur in polymyalgia rheumatica (PMR). About 45% of patients with giant cell arteritis present with symptoms of PMR. Other vasculitides may also lead to arthralgia and myalgia. While shoulder and pelvic pain is characteristic for PMR pain often also occurs in the back of the neck and in the region of the thoracic spine. In addition, patients often present with malaise, morning stiffness and weight loss. CRP and ESR are elevated. Ultrasound and MRI delineate minor synovitis, tenosynovitis and bursitis in the shoulder. Hip joint synovitis and trochanteric bursitis are also commonly seen. PMR should be distinguished from rheumatoid arthritis. The initial treatment comprises a prednisolone dose of 15-25 mg/day, followed by a weekly decrease of 1-2.5 mg. Once 10 mg/day has been reached the dose should be reduced more slowly.

Abstract
Giant cell arteritis and Takayasu's arteritis are classified as primary large-vessel vasculitides. Inflammatory cell infiltrates and cytokines induce destruction and hyperplasia of the vessel wall, leading to stenoses or aneurysms. When extracranial large arteries are involved, there is often a similar clinical and radiologic disease pattern of an inflammatory aortic arch syndrome. Rare causes of large-vessel vasculitis include Behçet's disease, association with other autoimmune diseases, and infection. Depending on the localization, imaging is usually performed by means of duplex ultrasound, magnetic resonance imaging, computed tomography, or positron emission tomography. These imaging modalities are used not only to establish the diagnosis but also to determine the disease extent and activity and to perform follow-up in the course of medical therapy. Angiography offers the option to perform interventional therapy for vascular stenoses and occlusions.

Abstract
PURPOSE OF REVIEW Ultrasonography, MRI, and PET are increasingly studied in large-vessel vasculitis. They have broadened our knowledge on these disorders and have a place in the diagnostic approach of these patients. RECENT FINDINGS Temporal artery ultrasonography can be used to guide the surgeon to that artery segment with the clearest 'halo' sign to perform a biopsy, or in experienced hands can even replace biopsy. The distal subclavian, axillary, and brachial arteries can also be examined. High-resolution MRI depicts superficial cranial and extracranial involvement patterns in giant cell arteritis (GCA). Contrast enhancement is prominent in active inflammation and decreases under successful steroid therapy. Presence of aortic complications such as aneurysm or dissection can be ruled out within the same investigation. Large thoracic vessel FDG-uptake is seen in the majority of patients with GCA, especially at the subclavian arteries and the aorta. FDG-PET cannot predict which patients are bound to relapse, and once steroids are started, interpretation is hazardous, which makes its role in follow-up uncertain. Increased thoracic aortic FDG-uptake at diagnosis of GCA may be a bad prognostic factor for later aortic dilatation. In patients with isolated polymyalgia rheumatica - who have less intense vascular FDG uptake - symptoms are caused by inflammation around the shoulders, hips, and spine. SUMMARY Ultrasonography, MRI, and PET remain promising techniques in the scientific and clinical approach of large-vessel vasculitis.

Abstract
Introduction Idiopathic aortitis is a rare condition characterized by giant cell or lymphoplasmacytic inflammation of the aorta. The purpose of this study was to describe risk factors for the development of idiopathic aortitis. Methods We conducted a case control study of 50 patients who were age-matched with two control subjects with non-inflammatory ascending aortic aneurysms. We examined whether the prevalences of gender, hypertension, hyperlipidemia, diabetes mellitus, smoking, family history of any aortic aneurysms, and elevated inflammatory markers differed between cases and controls. Results The mean age of cases was 71.6 ± 8.9 years and that of controls was 71.1 ± 8.9 years. We found female gender (odds ratio [OR] 2.41, 95% confidence interval [CI] 1.20 to 4.85; P = 0.014) and active smoking (OR 3.37, 95% CI 1.12 to 10.08; P = 0.03) to be associated with idiopathic aortitis. The association with smoking persisted after adjustment for gender (OR 3.24, 95% CI 1.05 to 9.96; P = 0.04). There was a trend toward lower prevalence of diabetes mellitus in cases (OR 0.39, 95% CI 0.11 to 1.43; P = 0.16) but no difference in prevalences of other risk factors. The median pre-operative erythrocyte sedimentation rate (ESR) was 20 mm/hour in cases (n = 13) and 9 mm/hour in controls (n = 22). The median pre-operative C-reactive protein (CRP) levels were 12 mg/L in cases (n = 8) and 3 mg/L in controls (n = 6) (normal: <8 mg/L). A higher proportion of cases versus controls had elevations in ESR (38% versus 9%; P = 0.075) and CRP (62% versus 0%; P = 0.031). Conclusions Gender and smoking may interact in complex mechanisms with immune and proteolytic pathways in older, less distensible thoracic aortas. Elevated acute-phase reactants as a marker of systemic inflammation may be present in some patients.

Abstract
Clinicians who treat patients with giant cell arteritis (GCA) face many unresolved challenges. Visual loss still occurs in 15% to 20% of patients despite the availability of therapy for the disease that is generally effective. Aneurysm formation and large vessel stenosis are increasingly recognized complications. Substantial iatrogenic morbidity stems from glucocorticoid therapy, and recent trials have failed to identify an efficient steroid sparing agent. In this review, the authors address five major clinical conundrums in the management of GCA.
