Factors Determining Serologic Response to Treatment in Patients with Syphilis

Abstract

Syphilis incidence rose 223% from 2003 to 2007, affecting mostly HIV-positive men, men who have sex with men, and immigrants. Men, patients in the late stages of syphilis, and HIV-positive persons may be at increased risk of serologic failure. Antiretroviral therapy significantly reduced the time to achieve response to syphilis treatment in HIV-positive patients.
