The aim of the present study was to investigate the seropositivity of parvovirus B19 in patients with ankylosing spondylitis (AS). Material and Methods: The patient group consisted of 43 patients with ankylosing spondylitis; the control group consisted of 70 subjects who did not have any bone joints complaints. Anti-parvovirus B19 IgM and IgG antibodies were measured by ELISA. Results: Parvovirus B19 IgM antibody positivity in patients with AS was significantly higher than that in the control group (p<0.001). Conclusion: The high frequency of anti-parvovirus B19 IgM positivity in patients with AS suggests that the virus reactivates or persists in these patients due to immuno deficiency.trinfo:eu-repo/semantics/openAccessAnkylosing spondylitisimmuno deficiencyparvovirus B19Article601374010.5152/tftrd.2014.280002-s2.0-84899736811N/AWOS:000340590100008Q4
