E3S14 - Syphilis Management for Australian Clinical Exams

Welcome to Season 3 of AMC Clinical Deep Dive!

Driven by Treponema pallidum, syphilis prevalence is rising across Australia, particularly among women of reproductive age. This episode deconstructs the ASHM guidelines for OSCE success. Learn to differentiate early (<2 years) versus late (>2 years) syphilis, interpret complex serology (CMIA screening, TPPA confirmation, and RPR activity tracking), and administer first-line Benzathine Benzylpenicillin (2.4 MU IMI stat vs. 3 weekly doses). We cover critical safety steps: warning patients about the Jarisch-Herxheimer reaction, managing syphilis in pregnancy, executing 3/6/12-month contact tracing, and evaluating a 4-fold RPR drop at follow-up.

Pro Tip: In your OSCE, never mistake early latent syphilis for late latent syphilis! If the exact duration of infection is uncertain, always treat as late latent (>2 years) with 3 weekly doses of Benzathine Benzylpenicillin (2.4 MU IMI weekly). Always forewarn patients about the Jarisch-Herxheimer reaction (fever, rigours, and headache 6–12 hours post-treatment) so they aren't alarmed by acute systemic symptoms. For pregnant patients, penicillin is non-negotiable—if allergic, they must undergo hospital desensitisation because alternative regimens are not proven effective in preventing congenital syphilis. Finally, document mandatory Syphilis Registry / Health Department notification and schedule RPR testing at 3 and 6 months, aiming for a 4-fold drop in titer (e.g., from 1:16 to 1:4) to secure top clinical reasoning marks!
