Vasculitis is classified by the size of the blood vessels affected by inflammatory reactions. In vasculitis of skin, many patients show obvious purpura and ulceration. Because many vasculitides can be noticed by these skin manifestations, dermatologists should be well informed about vasculitis. It is difficult to manage vasculitis after the diagnosis has been performed, and it is particularly d...

Kawasaki disease (KD) is a form of systemic vasculitis characterized by inflammation blood vessels throughout the body, and its exact cause remains unknown [...]

BACKGROUND Multiple choroidal granulomas are a rare presentation of tuberculosis. Choroidal granulomas in immunocompetent patients can pose difficulty in diagnosis as in most cases systemic examination may not reveal any evidence of tuberculosis. We report a case of bilateral multiple choroidal granulomas with systemic vasculitis-like features and disseminated tuberculosis in an immunocompetent...

OBJECTIVE To estimate the incidence rate of clinically apparent arterial thrombotic events and associated comorbidities in patients with primary systemic vasculitis. METHODS Using large cohort administrative data from Quebec, Canada, we identified patients with vasculitis, including polyarteritis nodosa (PAN) and granulomatosis with polyangiitis (GPA). Incident acute myocardial infarctions (A...

OBJECTIVES Over the last two decades, increasing interest has been focused on the association between autoimmune polyneuropathies and anti-neuronal autoantibodies in immune-mediated polyneuropathy. The possible appearance of these autoantibodies in systemic diseases that are not limited to the nervous system has not been fully addressed yet. METHODS We evaluated 32 patients with systemic lupu...

LTA: lymphocytic thrombophilic arteritis MLA: macular lymphocytic arteritis NBUVB: narrow-band ultraviolet B INTRODUCTION Macular lymphocytic arteritis (MLA) and lymphocytic thrombophilic arteritis (LTA) are terms used to describe an indolent, cutaneous medium-vessel vasculitis that has been suggested to follow a benign but persistent disease course. Pathologically, this condition is characteri...

Vasculitis (angiitis) is a systemic autoimmune disease that often causes fatal symptoms. We aimed to isolate cDNA markers that would be useful for diagnosing not only vasculitis but also other autoimmune diseases. For this purpose, we used stepwise subtractive hybridization and cDNA microarray analyses to comprehensively isolate the genes whose expressions are augmented in peripheral blood mono...

BACKGROUND Urticarial vasculitis is a small-vessel vasculitis, presenting clinically as persistent urticarial skin lesions and microscopically as leucocytoclastic vasculitis. Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a distinct type of urticarial vasculitis with multiorgan involvement, whose etiology and link with other diseases are still unknown. Some authors have suggested t...

Takayasu's arteritis (TA) is a systemic vasculitis that affects mainly the aorta and its major branches. Despite being the third most frequent vasculitis in childhood, the occurrence of TA in the pediatric age group is scarce. We report three cases of TA in children, emphasizing signs and symptoms, angiographic alterations and therapeutics.

We report a patient with chronic bronchiectasis who developed systemic vasculitis. The patient was initially treated with immunosuppression; however, the addition of antibiotic therapy improved control of her vasculitis and the need for immunosuppression was reduced. Chronic bronchial suppuration may have an aetiological role in the pathogenesis of this condition.
