Immune Complex-positive Glomerulonephritis in Antineutrophil Cytoplasmic Antibody-positive Patients

Antineutrophil cytoplasmic antibody-positive pauci-immune glomerulonephritis associated with mantle cell lymphoma

Renal involvement in non-Hodgkin lymphoma, especially mantle cell lymphoma (MCL) is rare. A 77-year-old man presented with acute kidney injury (AKI), which rapidly progressed to dialysis dependence. Kidney biopsy revealed patchy B-cell lymphocytic aggregates in the interstitium, which were positive for cyclin D1, consistent with atypical CD5-negative MCL as confirmed by the detection of translo...

Myeloperoxidase-antineutrophil cytoplasmic antibody-positive crescentic glomerulonephritis associated with benzylthiouracil therapy: report of the first case.

Grave’s disease is a common form of autoimmune thyroiditis which has been successfully treated with anti-thyroid drugs for more than half a century. However, these drugs may cause major complications including agranulocytosis, hepatotoxicity and immunological disturbances such as lupus erythematosus syndrome. Anti myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) mediated crescenti...

HLA-B52-positive Aortitis with Antineutrophil Cytoplasmic Antibody-associated Vasculitis

A 73-year-old man presented with a 1-month history of fever and numbness of the bilateral upper and lower extremities. Laboratory tests showed positive myeloperoxidaseantineutrophil cytoplasmic antibody (ANCA) results (296 U/ mL). Computed tomography (CT) showed wall thickening in the thoracic aorta and common carotid arteries (Picture A), and gallium single-photon emission CT/CT showed accumul...

Antineutrophil cytoplasmic antibody-associated glomerulonephritis in type II diabetes mellitus.

Antineutrophil cytoplasmic antibody-positive conversion and microscopic polyangiitis development in patients with idiopathic pulmonary fibrosis

BACKGROUND Increasing evidence indicates that antineutrophil cytoplasmic antibody (ANCA)-positive conversion occurs in patients initially diagnosed with idiopathic pulmonary fibrosis (IPF) and as a result, some of these patients develop microscopic polyangiitis (MPA). However, the incidence density of these patients is not well known. OBJECTIVES To explore the incidence of ANCA-positive conve...
