A case of sjögren's syndrome with severe anemia due to myelitis
1986
An unusual case of Sjögren's syndrome presenting with severe anemia as the predominant clinical feature is described. Histological examination of a bone marrow biopsy specimen demonstrated that the patient's anemia was caused by myelitis and vasculitis of the small intraosseous vessels. Our report might stimulate a more thorough investigation of bone marrow in patients with connective tissue diseases and anemia.
IL-33 is overexpressed in the inflamed arteries of patients with giant cell arteritis.
2013
OBJECTIVE: To study the expression of interleukin (IL)-33 and to evaluate its relationship with macrophage polarisation in artery biopsy specimens from patients with giant cell arteritis (GCA). METHODS: IL-33, ST2, p-STAT-6 and perivascular IL-1 receptor-associated kinase 1 (p-IRAK1) tissue distribution was evaluated by immunohistochemistry. Inducible nitric oxide synthase and CD163 were also used by immunohistochemistry to evaluate the M1 and M2 polarisation, respectively. Quantitative gene expression analysis of IL-33, T-helper (Th)2-related transcription factor STAT6, Th2 cytokines (IL-4, IL-5, IL-25) and interferon (IFN)-γ was performed in artery biopsy samples obtained from 20 patients…
Color Doppler Hemodynamics of Giant Cell Arteritis
1994
Objectives: To determine quantitative and qualitative hemodynamic alterations within the ophthalmic, central retinal, and short posterior ciliary arteries in patients with giant cell arteritis (GCA) proved by biopsy specimen. Design, Patients, and Setting: A consecutive case series of patients with GCA referred to an urban eye hospital who were evaluated with color Doppler imaging that was used to analyze orbital blood flow velocities and vascular resistance in 22 consecutive patients with GCA compared with age and sex-matched controls. Results: Patients with GCA all demonstrated significantly reduced central retinal and short posterior ciliary arterial mean flow velocities as well as signi…
Giant cell arteritis-related aortitis with positive or negative temporal artery biopsy: a French multicentre study.
2019
Objective: To compare the clinical presentation and outcome of giant cell arteritis (GCA)-related aortitis according to the results of temporal artery biopsy (TAB).Method: Patients with GCA-related...
Temporal headache and jaw claudication may be the key for the diagnosis of giant cell arteritis
2018
Background Temporal artery biopsy (TAB) is a surgical procedure with a low positive yield. The purpose of this study is to determine which variables are the most important in the giant cell arteritis (GCA) diagnosis. The objective of this evaluation is to improve the percentage of positive temporal artery biopsy and if possible, avoid the biopsy in some cases. Material and Methods A retrospective clinical study consisted of 90 patients who had undergone TAB at the Río Hortega Hospital (Spain) from January 2009 to December 2016. Clinical findings, erythrocyte sedimentation rates (ESR) and other laboratory parameters, American College of Rheumatology (ACR) criteria for GCA score and biopsy re…
Aneurysms of the coronary arteries in infants and children. A review, and report of six cases.
1977
In recent years large numbers of the so-called “mucocutaneous lymph node syndrome” or “Kawasaki's disease” have been described by Japanese workers, but instances of this disorder are only now being reported as isolated cases by European or North American physicians. The disease has, therefore, been considered to be a new entity. One of its most striking features is the development of aneurysms of the coronary arteries in infants or children, which may lead to sudden death. Aneurysms of the coronary arteries in childhood are rare, and hence it was considered relevant to report six such cases, and to examine their possible relationship to Kawasaki's disease. The pathological changes underlyin…
Stroke associated with giant cell arteritis: a population-based study
2014
Background Giant cell arteritis (GCA) is the most common vasculitis in people ≥50 years and can be associated with stroke. We aimed to evaluate the epidemiology and characteristics of stroke in patients with GCA. Methods All patients with a biopsy-proven diagnosis of GCA were identified among residents of the city of Dijon, France (152 000 inhabitants), between 2001 and 2012 using a prospective database. Among these, patients who suffered from stroke were retrieved by crossing data from the population-based Dijon Stroke Registry. Demographics and clinical features were recorded. We considered that the stroke was GCA-related if the stroke revealed GCA or occurred between the onset of symptom…
Brucellar aortitis and brucellar spondylitis
2015
Brucellosis is the most common bacterial zoonosis, and causes a considerable burden of disease in endemic countries. Cardiovascular involvement is the main cause of mortality due to infection with Brucella spp., and most commonly manifests as endocarditis, peripheral and cerebrovascular aneurysms, or arterial and venous thrombosis. We report a case of brucellosis presenting as bacteremia and aortic endarteritis 18 years after the last known exposure to risk factors for brucella infection. The patient was treated with doxycycline, rifampin, and gentamicin, and underwent surgical repair of a penetrating aortic ulcer, with a good clinical recovery. We review the signs and symptoms, diagnostic …
Polymyalgia rheumatica and vertebral fractures: a 1-year pilot controlled study
2010
No data exist about the possibility that vertebral fracture in PMR patients could be independent of steroid therapy. For this reason, we aimed to investigate this topic by a case cohort study with a 1-year follow-up for each patient. We selected ten consecutive patients who experienced vertebral fractures (VF-group) during the first month of 1-year follow-up period and without any other significant associated condition. As a control group we studied ten control patients, without vertebral fractures and with a follow-up of 1 year, randomly selected among a larger group of patients affected by polymyalgia rheumatica. The following data were analysed: eritrosedimention rate (ESR), visual analo…
OP0193 Inflammation of adventitial nerves occurs in giant cell arteritis patients and it is characterized by inflammasomes, upr and autophagy activat…
2017
Background Vascular adventitia is a major site of immune surveillance and inflammatory cell trafficking and is the most complex compartment of the vessel wall comprising fibroblasts, dendritic cells and macrophages, progenitor cells, vasa vasorum, pericytes and adrenergic nerves. It has been proposed that activation of adventitial nerves and release of sensory neuropeptides from their peripheral terminals may leads to neurogenic inflammation. Giant cell arteritis (GCA) is an immune-mediated disease of unknown etiology in which the inflammatory process seems to start from the adventitia of affected arteries. Objectives aim of the study was to evaluate the occurrence of adventitial nerves inf…
