Vasculitis and Multicenter Trial of Treatment in ANCA Associated Vasculitis

Differentiation of Cocaine-Induced Midline Destructive Lesions from ANCA-Associated Vasculitis

Introduction: Cocaine-induced midline destructive lesions (CIMDL) are complications of regular nasal cocaine inhalation. CIMDL can mimic systemic diseases with positive anti-neutrophil cytoplasmic antibodies (ANCA), such as granulomatosis with polyangiitis (GPA).   Case Report: In this article, we describe the case of a young woman who presented with nasal perforation induced by cocaine, al...

Infective endocarditis mimics ANCA associated glomerulonephritis

Background: Sub-acute bacterial endocarditis (SBE) rarely presents with features of a small vessel vasculitis. Patients with SBE can also develop multiple serological abnormalities including ANCA. In this report, we present a case of infective endocarditis mimicked ANCA associated glomerulonephritis.Case presentation: A 57-year old male with a clinical picture of rapidly progressive renal failu...

C-ANCA Positive Vasculitis in a Case of Amyloidosis

Severity-based treatment for Japanese patients with MPO-ANCA-associated vasculitis: the JMAAV study

We (JMAAV [Japanese patients with MPO-ANCA-associated vasculitis] Study Group) performed a prospective, open-label, multi-center trial to evaluate the usefulness of severity-based treatment in Japanese patients with myeloperoxidase-anti-neutrophil cytoplasmic antibodies (MPO-ANCA)-associated vasculitis. Patients with MPO-ANCA-associated vasculitis received a severity-based regimen according to ...

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. ...
