ANCA-associated small-vessel vasculitis.
Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis is the most common primary systemic small-vessel vasculitis to occur in adults. Although the etiology is not always known, the incidence of vasculitis is increasing, and the diagnosis and management of patients may be challenging because of its relative infrequency, changing nomenclature, and variability of clinical expression. ...
متن کاملFamilial clusters of ANCA small-vessel vasculitis
Small-vessel vasculitides associated with the presence of antineutrophil cytoplasmic antibodies in the serum are characterized by inflammation and necrosis of small vessels. A pauci-immune necrotizing crescentic glomerulonephritis typically occurs when there is renal damage. Pathogenesis of these diseases remains unclear although infectious, genetic and environmental factors have been involved....
متن کاملPathophysiology of ANCA-Associated Small Vessel Vasculitis
Antineutrophil cytoplasmic autoantibodies (ANCAs) directed to proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA) are strongly associated with the ANCA-associated vasculitides--Wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome. Clinical observations, including the efficacy of B-cell depletion via rituximab treatment, support--but do not prove--a pathogenic role fo...
متن کاملTreatment of ANCA-Negative Small Vessel Vasculitis
Cryoglobulinaemia refers to circulating cryoglobulins. Cryoglobulins are immunoglobulins, which precipitate in temperatures below 37oC and dissolve upon rewarming [2]. Cryoglobu‐ linaemia is classified in 3 types based on clonality and immunoglobulin class. In particular, type I consists of monoclonal IgM or IgG immunoglobulin, type II is a mixture of monoclo‐ nal IgM and polyclonal IgG, while ...
متن کاملPropylthiouracil-induced ANCA-negative cutaneous small vessel vasculitis
Propylthiouracil (PTU) is a commonly used medication for the treatment of hyperthyroidism. PTU is known to cause different adverse reactions including autoimmune syndromes. PTU-induced autoimmune syndromes can be classified into drug-induced lupus or drug-induced vasculitis. Differential diagnoses could be very challenging. PTU-induced vasculitis is more common than PTU-induced lupus, and has a...
