Asymptomatic latent syphilis in geriatric patients in association with stoke: Analysis using routine syphilis tests.

Introduction: We investigated the association between stroke and asymptomatic latent syphilis (ALS) in geriatric patients.

Methods: This retrospective observational study included patients aged >65 years who underwent routine qualitative rapid plasma reagin (RPR) and Treponema pallidum Latex Agglutination (TPLA) tests at a 161-bed community acute care hospital with long-term care facilities in Kamakura, Japan, from August 2014 to February 2019. Asymptomatic patients with a positive TPLA test result were diagnosed with ALS.
