Abstract

PENA-WILCHES, Adalberto et al. ANCA-associated rapidly progressive glomerulonephritis in a patient with IgA nephropathy, case report. Rev. colom. nefrol. [online]. 2017, vol.4, n.2, pp.200-209. ISSN 2500-5006.  https://doi.org/10.22265/acnef.4.2.272.

IgA nephropathy is the most common glomerulonephritis, in which less than 10% of patients have a rapid decline of renal function. The histological findings of this group resemble those of vasculitis, with presence of crescents and fibrinoid necrosis. The coexistence of IgA nephropathy and neutrophil anti-cytoplasmic antibodies is infrequent, and the pathogenic role of these antibodies in IgA nephropathy is unclear. Here we describe a case of a patient with IgA nephropathy, rapidly progressive glomerulonephritis and neutrophil positive anti-cytoplasmic antibodies, and literature review is presented.

Keywords : IgA nephropathy; rapidly progressive glomerulonephritis; vasculitis; ANCA; crescents.
