Patients with this condition frequently test positive for ANCA and, even more frequently, for c-ANCA, ANA, antiphospholipid antibodies, leukopenia, and neutropenia.
The c-ANCA pattern is more related to GW, with a specificity of 90%, but its negativity is insufficient to rule out the diagnosis.
His serology was also positive for c-ANCA (anti-PR3), antinuclear antibody, and weakly positive for type III cryoglobulinemia.
Positive serum c-ANCA suggested the diagnosis of Wegener's granulomatosis, featuring with pauci-immune crescentic glomerulonephritis.
5-5 g/dL P-ANCA Positive * Negative C-ANCA Negative Negative Myeloperoxidase Ab 3 * < 0.
Asi, en la GPA el patron detectado mayoritariamente es el c-ANCA y en la PAM es el p-ANCA (20-22).
Six patients were positive for c-ANCA and 4 for p-ANCA.
WG is much more frequently associated with c-ANCA (figure 1).
Blood chemistry, blood counts, ESR, urine analysis, coagulation profile and antithrombin III, protein C, protein S, activated protein C resistance and antiphospholipid antibodies were within normal limits and immunological markers including immunoglobulins (Ig A, Ig G, Ig M), C3, C4, p-ANCA, c-ANCA and anti-DNA were negative.
