Prevalence of antineutrophil cytoplasmic antibody positivity in patients with Hodgkin's and non-Hodgkin lymphoma: a single center experience

Abstract

Hematological malignancies are associated with the release of different autoantibodies and rheumatological manifestations. Systemic vasculitides are rare in hematological malignancies, and antineutrophil cytoplasmic antibodies (ANCA) have not been described sufficiently in hematological malignancies. In this present prospective study, we examined the prevalence of ANCA and related disease in Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) patients in the southeast region of Turkey. We examined 119 patients with previously or newly diagnosed NHL and 60 patients with HL for the presence of ANCA and related autoimmune diseases between December 2002 and February 2007. ANCA positivity was detected in only 8 patients (4.4%); and all of these ANCA positivities were detected in patients in the HL group (13.3%); p-ANCA positivity was detected in 6 patients (3.3%); and c-ANCA positivity was detected in 2 patients (1.1%). There was statistically significant difference between patients with HL and NHL in terms of p-ANCA (p = 0.001) but none in c-ANCA (p = 0.111) positivity. None of the ANCA positive patients had vasculitides or rheumatic manifestations. In addition, we did not detect any ANCA positivity in the NHL group. In conclusion, ANCA positivities were detected only in HL patients; but we did not detect the association between ANCA positivities and rheumatic manifestations or vasculitis and also the different treatment responses in HL patients.
