Randomized Controlled Trial
Response to therapy following retreatment of serofast early syphilis patients with benzathine penicillin.
Persistent nontreponemal titers after treatment are common among patients with early syphilis. We retreated 82 human immunodeficiency virus-negative early syphilis participants who were serofast at 6 months using benzathine penicillin. Only 27% exhibited serological response after retreatment and after an additional 6 months of follow-up.
