Crescentic transformation in primary membranous glomerulonephritis.

Comment on "membranous glomerulonephritis associated with mieloperoxidase antineutrophil cytoplasmic antibody-associated glomerulonephritis".

To the Editor: We read with interest the report of Dr. Guang-Yu Zhou, about a case of Membranous Glomerulonephritis with crescentic transformation. Acute crescentic transformation is a rare but well described event in patients with membranous glomerulonephritis. The concomitant occurrence of a vasculitic glomerulonephritis and membranous nephropathy in the same patient is unusual. We report her...

Combined membranous nephropathy and crescentic glomerulonephritis with concurrent anti-glomerular basement membrane antibody and myeloperoxidase-specific anti-neutrophil cytoplasmic antibody.

We report a case of a 71-year-old man with rapidly progressive nephritic syndrome and dual positivity for anti-glomerular basement membrane antibody and myeloperoxidase-specific anti-neutrophil cytoplasmic antibody. Renal biopsy revealed crescentic, mainly cellular, glomerulonephritis with granulomatous lesions, and advanced membranous changes. Membranous nephropathy had apparently existed for ...

Crescentic glomerulonephritis associated with membranous nephropathy in a case with primary Sjögren's syndrome.

A case of membranous nephropathy and myeloperoxidase anti-neutrophil cytoplasmic antibody-associated glomerulonephritis

Membranous nephropathy (MN) may be a primary disease or secondary to autoimmune conditions such as systemic lupus erythematosus, infection (for example, with hepatitis B or C virus), cancer or drugs. In primary MN, crescents are rarely observed. Therefore, the presence of crescents suggests another underlying disease, for example lupus nephritis, anti-glomerular basement membrane disease or ant...

Necrotizing and crescentic glomerulonephritis with membranous nephropathy in a patient exposed to levamisole-adulterated cocaine

Levamisole is an antihelminthic agent widely used as an adulterant of illicit cocaine recently implicated as a cause of antineutrophil cytoplasmic antibody (ANCA)-associated microscopic polyangiitis in cocaine abusers. An isolated case of membranous nephropathy (MN) associated with levamisole exposure has also been reported. We report the first case, to our knowledge, of a patient with both mic...
