Filter by:Giant cell arteritis (GCA) is a medium to large vessel vasculitis with a predilection for the superficial cranial and intrathoracic arteries. Diagnosing the condition and predicting which patients will develop large vessel complications remains a challenge. There are limitations with temporal artery biopsy, magnetic resonance angiography and ultrasound of temporal arteries and American College of Rheumatology classification criteria. Positron emission tomography (PET) has been shown to be a useful modality in detecting inflammation in large intra-thoracic vessels but previously has not been able to accurately detect FDG uptake in the superficial cranial arteries due to poor spatial resolution. Newer scanners can perform finer cuts of the head and can detect uptake in these arteries. This study has three main components: 1. Cross sectional study assessing the accuracy of PET uptake in the superficial cranial and intrathoracic arteries of suspected GCA patients for the diagnosis of GCA 2. Cohort study assessing the prognostic implication of FDG aortic uptake on aortic diameter at 24 months 3. Cohort study assessing the Th1 and Th17 cytokine profile in patients with and without FDG PET uptake at 0, 6 and 24 months
Arterial inflammation will be compared using PET scanning in 3 groups: 1) Non-smokers, 2) Tobacco cigarette smokers, 3) Electronic cigarette users.
Giant cell arteritis (GCA or temporal arteritis or cranial arteritis) or Horton disease is a vasculitis that occurs in older adults, affecting vessels of medium and large caliber. The diagnosis of GCA is a challenge for general practitioners and specialists. Since 1970, it is based on a combination of clinical, biological and histological signs. Temporal artery biopsy (TAB) was the reference method until recently. However, TAB has many drawbacks. Therefore, researches of the past 20 years have been intended to develop alternative diagnostic methods. This was notably the case of the color Doppler ultrasound (CDU) since the description by Wolfgang Schmidt of the halo sign. Although European and British recommendations put CDU as second line method, many authors suggest the possibility to do without TAB in many cases. In addition, many practitioners believe that it is not "ethical" to use an invasive unprofitable procedure like TAB, and have already been using CDU in their routine practice. However, no diagnostic algorithm validating this approach in a prospective series has been published to date. Therefore, the present study aim at validating a diagnostic algorithm of giant cell arteritis using color Doppler imaging of temporal arteries and cervicocephalic axes as first screening method.
The purpose of this study is to measure arterial 99mTc-Tilmanocept uptake using single photon emission computed tomography (SPECT/CT) scanning in HIV infected subjects known to have subclinical coronary atherosclerosis as assessed by contrast-enhanced coronary computed tomography angiography (CCTA).
The purpose of this study is to learn about the impact of vasculitis on employment and income in patients with different systemic vasculitides. All patients enrolled in the Vasculitis Clinical Research Consortium (VCRC) Patient Contact Registry, living in USA or Canada, and followed for more than 1 year since the vasculitis diagnosis will be invited via email to participate in this study, based on an online survey.
The purpose of this study is to provide validation of patient-reported data in the VCRC Patient Contact Registry by comparing patient-reported data with data provided by the physician who is the primary provider caring for the patient's vasculitis. Patients enrolled in the Patient Contact Registry with Behcet's disease, eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA), giant cell arteritis (GCA), granulomatosis with polyangiitis (Wegener's) (GPA), microscopic polyangiitis (MPA), polyarteritis nodosa (PAN), and Takayasu's arteritis (TAK) were invited via email to participate in this study.
A cross-sectional study design and online questionnaire was used to assess the informational needs of patients with several different types of systemic vasculitis. Patients were recruited from within the Vasculitis Clinical Research Consortium (VCRC) online Patient Contact Registry1. Survey responses from participants in the VCRC Patient Contact Registry were compared to responses from a similar survey recently administered to patients within a United Kingdom (UK) based vasculitis support group (Vasculitis UK).
The purpose of this study is to learn about how patients with vasculitis think about their illness and to assess to what extent patient perceptions of illness are associated with physical, mental, and social functioning
The purpose of this study is to learn about reproductive health, including fertility and pregnancies, in people with vasculitis.
First-line tocilizumab treatment during 6 months could permit rapid steroid-tapering and induction of remission in Takayasu arteritis (TA).
