Özet

© 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.Increased DNA damage has been suggested to contribute to the pathogenesis of chronic inflammatory diseases, but controlled studies are lacking in ankylosing spondylitis (AS). Therefore, we assessed oxidative stress, oxidative DNA damage, chromosomal DNA damage, cell proliferation and cell death in the peripheral blood lymphocytes of patients with AS as well as the possible role of DNA damage in the development of the disease. In total, 25 newly diagnosed AS patients who had not received anti-inflammatory agents and 25 healthy controls were recruited. Oxidative DNA damage was assessed by plasma 8-hydroxy-2′-deoxyguanosine (8-OHdG) levels, and chromosomal DNA damage was assessed by the cytokinesis-block micronucleus cytome (CBMN-cyt) method. Compared to controls, the micronucleus (MN) frequencies, nucleoplasmic bridge (NPB) frequencies, nuclear bud (NBUD) frequencies, apoptotic cell frequencies, necrotic cell frequencies and plasma 8-OHdG levels were significantly higher in patients with AS (p < 0.001, p < 0.05, p < 0.01, p < 0.001, p < 0.001, and p < 0.001, respectively), and the metaphase cell numbers, binucleated (BN) cell frequencies and nuclear division index (NDI) values were significantly lower in patients with AS (p < 0.01, p < 0.001 and p < 0.001, respectively). Thus, the present findings suggested that oxidative stress, oxidative DNA damage, and chromosomal DNA damage may be involved in the pathogenesis of AS similar to other chronic inflammatory diseases. In addition, the increased plasma 8-OHdG levels, MN frequencies, NPB frequencies and NBUD frequencies in AS patients may reflect an increased cancer risk.
