Popis: Sera from 210 patients with APSGN, were tested for the presence of ANCA (IgG-isotype). Indirect immunofluorescence (IF) on ethanol fixed human PMNs was used, and for those positive sera, ELISA kits for PR3 (Proteinase 3) and MPO (Myeloperoxidase) was performed. ANCA were detected in 9% (18 out of 210 cases) in a predominantly diffuse cytoplasmic staining pattern in 14 cases (77%), and in a perinuclear pattern in the remaining 4 cases (22%). Anti-MPO was found in 4 cases (C-ANCA 3; P-ANCA 1) and anti-PR3 was always negative. The presence of ANCA was significantly associated with a more severe glomerular disease as assessed by the serum creatinine value and the crescents formation.
