Prognostic Value of Histologic Classification of ANCA-Associated Glomerulonephritis

Histopathologic classification of ANCA-associated glomerulonephritis.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is the most common cause of rapidly progressive glomerulonephritis worldwide, and the renal biopsy is the gold standard for establishing the diagnosis. Although the prognostic value of the renal biopsy in ANCA-associated glomerulonephritis is widely recognized, there is no consensus regarding its pathologic classification. We pre...

Infective endocarditis mimics ANCA associated glomerulonephritis

Background: Sub-acute bacterial endocarditis (SBE) rarely presents with features of a small vessel vasculitis. Patients with SBE can also develop multiple serological abnormalities including ANCA. In this report, we present a case of infective endocarditis mimicked ANCA associated glomerulonephritis.Case presentation: A 57-year old male with a clinical picture of rapidly progressive renal failu...

The Histopathological Classification of ANCA-associated Glomerulonephritis Comes of Age.

Pathological classification of anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis.

What drives human beings to classify? It seems as if it is within our nature to do so. Clinical classification systems for the systemic vasculitides were composed a long time ago, and they are constantly being revised and altered. The histopathological features of many diseases are so diverse that classification is called for. The histopathological classification for anti-neutrophil cytoplasmic...

ANCA serotype and histopathological classification for the prediction of renal outcome in ANCA-associated glomerulonephritis.

BACKGROUND The phenotype of renal involvement in anti-neutrophil cytoplasmic antibodies (ANCA) vasculitis has a major influence on survival, and histological subgrouping of diagnostic renal biopsies has been proposed to aid in the prediction of renal outcome. We aimed to validate this histological subgrouping and to investigate the additional value of ANCA serotype in the prediction of renal ou...
