Glomerulonefritis rápidamente progresiva asociada a endocarditis afebril y anca anti-proteinasa 3

Abstract: Resumen La endocarditis asociada a ANCA anti-PR3 e insuficiencia renal plantea un dilema tanto en su diagnóstico como tratamiento. Para abordar una revisión de dicho tema, se presenta el caso de un paciente con glomerulonefritis rápidamente progresiva secundaria a endocarditis subaguda por Enterococcus faecalis y positividad para ANCA anti-PR3. El diagnóstico diferencial principal se establecería entre una afectación renal de una vasculitis asociada a ANCA no diagnosticada previamente vs una glomerulonefritis … Show more

“…ANCA-positive infective endocarditis affects the kidneys in approximately 31% of patients, and they most commonly present with haematuria [3]. In such patients, histological analysis of biopsied renal tissue may vary from focal segmental glomerulonephritis, with or without fibrinoid necrosis, to diffuse proliferative glomerulonephritis, with extra capillary proliferation [8,12,19,20]. Most patients have immunoglobulin deposits and C3 complement present in their glomerular blood vessels during immunofluorescence staining, which can partially explain the hypocomplementemia in our patients [12,19].…”

Most patients have immunoglobulin deposits and C3 complement present in their glomerular blood vessels during immunofluorescence staining, which can partially explain the hypocomplementemia in our patients [12,19]. However, in about 13% of patients, immune complex deposits are absent or rare, and histologic imaging is consistent with pauci-immune glomerulonephritis [20].…”
