Behcet disease (BD) is a chronic systemic vasculitis and considered as an autoimmune disease. Although rare, BD can be fatal due to ruptured vascular aneurysms or severe neurological complications. To date, no known biomarker has been reported for this disease, making it difficult to diagnosis in the clinics. To undertake this challenge, we employed the HuProt arrays, each comprised of~20,000 unique human proteins, to identify BD-specific autoantibodies using a Two-Phase strategy established previously. In Phase I, we profiled the autoimmunity on the HuProt arrays with 75 serum samples collected from 40 BD patients, 15 diagnosed autoimmune patients who suffer from Takayasu arteritis (TA; N=5)), ANCA associated vasculitis(AAV; N=5), and Sjogren's syndrome(SS; N=5), and 20 healthy subjects, and identified 20 candidate autoantigens that were significantly associated with BD...

Merkel cell carcinoma (MCC) is a highly aggressive cutaneous neuroendocrine tumour that is increasing in incidence. We report a case of a 92-year-old white man on long-term immunosuppression for temporal arteritis who presented with a Merkel cell tumour on his left cheek. A wide local excision was performed and the defect was reconstructed with a full-thickness skin graft. Four years later, the patient re-presented with a Merkel cell tumour arising from the right supraclavicular donor site. To our knowledge, this is the first report of a recurrence of MCC into a donor site...

BACKGROUND: Antibody-mediated rejection is a frequent cause of graft failure; however, prognostic indications of this complication have not been well defined. The aim of this study was to evaluate the association of histopathological and clinical features and to determine the effect of these findings on allograft survival in patients with AMR. METHODS: Fifty-two patients suffered from AMR (30 male; mean age 39 ± 11 years) were included in the study. Data were investigated retrospectively and graft survival was analyzed...

Tumor necrosis factor (TNF) inhibitors have exhibited certain clinical efficacy in treating refractory Takayasu arteritis (TA), albeit with severe adverse effects. We aimed to explore the anti-TNF function of resveratrol, a natural compound, in the treatment of TA. A total of 271 patients diagnosed of acute TA were enrolled in this clinical trial, who were then randomized to be administered 250mg resveratrol or placebo on a daily basis for a period of 3 months, and revisited biweekly to assess treatment outcomes...

We herein describe a surgical case of pulmonary involvement in Takayasu's arteritis with pulmonary infections of nontuberculous mycobacteria. A 24-year-old female was admitted to our hospital because of a recurrent fever, and contrast-enhanced computed tomography of the chest revealed the occlusion of the right pulmonary artery and cavitary lesions in the right lower lobe of the lung. A further examination of the neck revealed the occlusion of aortic branches, and the patient was diagnosed with Takayasu's arteritis...

Takayasu arteritis (TA) is a chronic large-vessel vasculitis of unclear pathogenesis. A recent genome-wide association study (GWAS) has revealed that the FCGR2A/FCGR3A, EEFSEC, RPS9/LILRB3, RIPPLY2 and MLX genes confer susceptibility to TA. We investigated the linkage between presumptive TA-related genes (FCGR2A/FCGR3A, EEFSEC, RPS9/LILRB3, RIPPLY2 and MLX) and TA in the Han Chinese population. We performed a large case-control multi-center study of 412 Han Chinese TA patients and 597 ethnically matched healthy controls...

Although a glucocorticoid (GC)-sparing strategy is needed for patients with giant cell arteritis (GCA) suffering from refractory disease or serious treatment-related complications, evidence of efficacy in this setting of immunosuppressive drugs and biotherapies is lacking. Herein, we evaluated the GC-sparing effects and tolerability of addition of dapsone (DDS) to prednisone therapy in patients with GCA. We retrospectively assessed data on 18 GCA patients who received DDS as a first-line treatment (DDS-1 group) and 52 patients who received it as a second- or third-line treatment for refractory GCA, with or without excessive GC-related toxicity (DDS-2 group)...

According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

BACKGROUND: Transient monocular vision loss (TMVL) is an alarming symptom owing to potentially serious etiologies such as thromboembolism or giant cell arteritis. Our objective is to describe the phenomenon of TMVL present on awakening, which may represent a distinct and benign entity. METHODS: We performed a retrospective observational case series of 29 patients who experienced TMVL on awakening. Patients who described monocular dimming or blackout of vision were included, and those with blurred vision, concurrent eye pain, and binocular vision loss were excluded...

Emboli from an atrial myxoma resulted in asymptomatic segmental retinal and choroidal arterial hyperfluorescent lesions on retinal angiography, mimicking an arteritis. The retinal lesions disappeared after removal of the atrial myxoma. Endothelial trauma by embolic material appears to be the mechanism of the angiographic findings.

PURPOSE OF REVIEW: Takayasu arteritis has long been considered as an uncommon disease, rather specific to the Far-East; however recent surveys show that the disease can be seen in all ethnicities around the world with increasing prevalence rates. Nowadays, it would not be fair to consider Takayasu arteritis as a rare disease. RECENT FINDINGS: Although involvement of the thoracic aorta and its branches was more common among females, males had a tendency toward limited involvement of the abdominal aorta and its branches...

OBJECTIVE: Patients with organ- or life-threatening vasculitis receive high cumulative glucocorticoid (GC) doses during their disease course. GC have diabetogenic effects, but the risk of diabetes mellitus (DM) related to vasculitis therapy is not well characterized. We assessed the DM risk among patients diagnosed with giant cell arteritis (GCA) or granulomatosis with polyangiitis (GPA), i.e., patients with relatively common forms of systemic vasculitis. METHODS: We used Danish healthcare registries to identify 1682 patients diagnosed with GCA and 342 patients diagnosed with GPA from 1997 to 2015 and to obtain information regarding medication exposures...
