OBJECTIVES: Giant cell arteritis (GCA) is a vasculitis that occurs in older adults, affecting vessels of medium and large caliber. GCA diagnosis is a challenge for general practitioners and specialists. The aim of this study was to retrospectively analyse performances of temporal artery biopsy (TAB) and color duplex ultrasonography (CDU) for GCA diagnosis. METHODS: All patients with suspicion of GCA and who underwent both TAB and CDU between April 2009 and March 2014 were included in the study...

Nowadays noninvasive vascular imaging has an important role in the diagnostic work-up of the large vessel vasculitides (LVV), most importantly giant cell arteritis (GCA) and Takayasu arteritis. Among the imaging modalities available, ultrasound (US) has several important advantages, including low costs, rapid and repetitive availability without exposure to radiation, and high spatial resolution for assessment of large and medium-sized arteries. Therefore, US can be regarded the first line imaging method in suspected LVV...

PURPOSE: To describe a patient presenting with suspected giant cell (temporal) arteritis (GCA) in whom subsequent temporal artery biopsy showed luminal narrowing by medial calcification, metaplastic ossification, and fibrointimal proliferation, consistent with calciphylaxis. METHODS: A 55-year-old man with end-stage renal disease presented with unilateral loss of vision and elevated erythrocyte sedimentation rate and was initially treated as though he had GCA; however, a subsequent temporal artery biopsy showed marked luminal narrowing by medial calcification, metaplastic ossification, and fibrointimal proliferation, consistent with calciphylaxis...

OBJECTIVE: Data on the presence of varicella-zoster virus (VZV) in temporal arteries of patients with giant cell arteritis (GCA) are controversial. We analyzed VZV infection in temporal arteries from Italian patients with temporal artery biopsy (TAB)-positive GCA, TAB-negative GCA, and controls. METHODS: A total of 79 formalin-fixed, paraffin-embedded (FFPE) TABs performed between 2009 and 2012 at a single institution from 34 TAB-positive GCA patients, 15 TAB-negative GCA patients, and 30 controls were retrieved...

Giant cell arteritis may lead to irreversible blindness due to an anterior ischemic optic neuropathy or central retinal artery occlusion. Diagnosis of the giant cell arteritis is sometimes a problem: Difficulties may arise since a negative biopsy can not rule out the diagnosis. This case report demonstrates acute changes in the temporal artery as demonstrated by Ultrasound Biomicroscopy and documents its course during therapy with corticosteroids.

Although clinical signs and symptoms of giant cell arteritis improve promptly after starting glucocorticoid therapy, reports have suggested that the vascular inflammation may persist. To assess the duration and quality of histopathologic changes in treated patients, we prospectively obtained second temporal artery biopsies in patients treated for 3 to 12 months after their first diagnostic biopsy. Forty patients (28 women, 12 men, median age 77 years) agreed to have a second temporal artery biopsy randomly assigned to 3, 6, 9, or 12 months subsequent to the first...

OBJECTIVES: To assess the validity of Doppler ultrasound in the diagnosis of giant cell arteritis (GCA), using the American College of Rheumatology (ACR) criteria and biopsy and using as gold standard the patient's definitive clinical diagnosis. METHODS: An observational, descriptive and analytical study of 451 consecutive patients with suspected GCA was conducted, and the clinical history and ultrasound findings of the patients were reviewed. The validity of ACR criteria, temporal arteritis biopsy (TAB) and Doppler ultrasound in the diagnosis of GCA was calculated using the final diagnosis of the doctor in charge as the gold standard...

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...

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: 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) and the use of glucocorticoids have both been associated with increased risk of venous thromboembolism (VTE). However, the possibility of confounding by indication has not been investigated. We undertook this study to examine the temporal risk of VTE in GCA patients before and after GCA diagnosis, accounting for confounders including glucocorticoid treatment. METHODS: We conducted a matched cohort study using an electronic medical record database representative of the UK population (1990-2013)...

While DNA replication and mitosis occur in a sequential manner, precisely how cells maintain their temporal separation and order remains elusive. Here, we unveil a double-negative feedback loop between replication intermediates and an M-phase-specific structure-selective endonuclease, MUS81-SLX4, which renders DNA replication and mitosis mutually exclusive. MUS81 nuclease is constitutively active throughout the cell cycle but requires association with SLX4 for efficient substrate targeting. To preclude toxic processing of replicating chromosomes, WEE1 kinase restrains CDK1 and PLK1-mediated MUS81-SLX4 assembly during S phase...

INTRODUCTION: In giant cell arteritis (GCA) headache of new onset due to inflammatory involvement of the temporal artery (TA) represents a diagnostic criterion. A widespread headache (WH) with scalp tenderness due to cranial arteritis can represent another manifestation of GCA. MATERIAL AND METHODS: In 225 elderly patients with polymyalgia rheumatica (PMR) followed in our rheumatologic outpatient clinic from 2004 until June 2016, the frequency of WH as the first clinical manifestation of GCA was evaluated...

BACKGROUND: Giant cell arteritis (GCA) is a relatively common form of primary systemic vasculitis, which, if left untreated, can lead to permanent sight loss. We compared ultrasound as an alternative diagnostic test with temporal artery biopsy, which may be negative in 9-61% of true cases. OBJECTIVE: To compare the clinical effectiveness and cost-effectiveness of ultrasound with biopsy in diagnosing patients with suspected GCA. DESIGN: Prospective multicentre cohort study...

Langerhans cell histiocytosis (LCH) is a rare histiocytic disorder of unpredictable clinical course and varied modes of presentation. The spectrum of presentation is wide, ranging from isolated eosinophilic granulomas to multiple lesions and diffuse systemic involvement. We present the case of a 52-year-old man, who presented with an 8-week history of worsening otalgia and superficial temporal tenderness attributed to otitis externa within the community and subsequently giant cell arteritis. Computed tomography and magnetic resonance imaging were undertaken due to atypical features, which demonstrated bony destruction within the right greater wing of the sphenoid, squamous part of temporal and mastoid bone, with middle cranial fossa communication...
