A Case of Rapid Progressive Neurosyphilis in Patient with Ankylosing Spondylitis Who Is Treating Anti-interleukin 17A Monoclonal Antibody, Secukinumab

ABSTRACT

Anti-interleukin 17A agent, secukinumab is remarkably effective for treating patients with ankylosing spondylitis. However, the main safety concern of secukinumab is an increased risk of infection. Generally, neurosyphilis occurs a few years after the primary syphilitic infection. Rare cases of progressing to neurosyphilis with a much lower latency were reported. We report a case of rapid progressive neurosyphilis involving hearing loss in both ears in a patient with ankylosing spondylitis who was treated with secukinumab.
