Rare adverse effect of a common drug: nitrofurantoin-induced 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...

Propylthiouracil Induced Vasculitis: A Rare Adverse Event

Microscopic polyangiitis: a rare ANCA-associated small-vessel vasculitis.

Microscopic Polyangiitis (MPA) is an autoimmune disease characterized by pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation. Because many different organ systems may be involved, a wide range of symptoms are possible in MPA. Cutaneous involvement is not frequent. We describe a young girl who presented with multi...

ANCA associated vasculitis and chronic lymphocytic leukemia: a rare association.

The aim of the present work is to discuss the report of a patient who had simultaneous diagnosis of two rare diseases, vasculitis related to antineutrophil cytoplasmic antibodies and chronic lymphocytic leukemia. Both are diseases that may be multisystemic and thus cause diagnostic confusion. In this case, the patient had renal, pulmonary, hematological, and ocular symptoms, which could be seco...

Concomitant drug- and infection-induced antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis with multispecific ANCA.

OBJECTIVE To report the first case of concomitant drug- and infection-induced antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) in a patient treated with propylthiouracil (PTU) and suffering from tuberculosis. PRESENTATION AND INTERVENTION A 28-year-old woman with PTU-treated hyperthyroidism presented with fever, purpura, pulmonary cavitations and ANCA to myeloperoxidas...
