Background.
End-stage renal disease (ESRD) risk in patients with antineutrophil cytoplasmic antibody- (ANCA-) associated glomerulonephritis (ANCA-GN) according to ANCA serotype and stratified by histological classification has not been previously investigated.
Methods.
Patients from the Norwegian Kidney Biopsy Registry (NKBR) between 1991 and 2012 who had biopsy-verified pauci-immune glomerulonephritis and positive antineutrophil cytoplasmic antibody serology were included.
Cases with ESRD during follow-up were identified in the Norwegian Renal Registry.
ESRD-free survival with proteinase 3 (PR3) versus myeloperoxidase- (MPO-) ANCA positivity stratified into 4 histological classes was investigated.
Results.
Three hundred fifty-eight patients, of whom 87 progressed to ESRD during follow-up, were included.
Patients with PR3- as compared to MPO-ANCA were younger (58 versus 64 years, p=0.001), had a higher percentage of males (62 versus 41%, p<0.001), had a lower percentage with a sclerozing glomerulonephritis pattern (4 versus 16%, p<0.001), and had a significantly higher cumulative ESRD-free survival (90 versus 80%, p=0.007) at 1-year follow-up.
No significant differences in cumulative ESRD-free survival with PR3- as compared to MPO-ANCA were observed by histological stratification.
Conclusion.
Advanced glomerular sclerosis is found more frequently in patients with MPO-ANCA, explaining the higher risk of ESRD.
ANCA serotypes have no impact on prognosis of patients with similar histological findings.
