Syphilis
How to diagnose?
next step after dx?
Screen with nontreponemal test: RPR (rapid plasma reagin) or VDRL (venereal dz research lab)
^use this to direct treatment as treponemal tests are positive for life
Confirm with treponemal test: flourescent treponemal antibody absorption or t. pallidum particle agglutination
report to health department
Causes of false positive RPR or VDRL
older age, pregnancy, cardiovascular disease, malaria, leprosy, recent immunizations

symptoms
how long until they resolve
painless chancre and lymphadenopathy 10-90 days from exposure
3-6 wks regardless of treatment

4-8 weeks after chancre
maculopapular rash/lymphanopathy, malaise, fever, condyloma lata
resolve after 2-6 wks regardless of treatment
Early Latent Syphilis
how to diagnose?
treatment
- +serology
- no past dx of syphilis
- no evidence of primary, secondary, or late
- suspect infection was in the last 12 months
must treat because of transplacental transmission
Late Latent Syphilis
how to diagnose?
- +serology
- no past dx of syphilis
- no evidence of primary, secondary, or late
- suspect infection was over a year ago
Tertiary syphilis
symptoms
gumma,
cardiovascular,
neurosyphilis,
benign late syphilis
symptoms of neurosyphilis

3-4 mill units IV q4hr for 10-14 days
OR procaine PCN 2.4 mil units IM daily x 10-14 days PLUS probenicid 500mg 4x daily 10-14 days
you start treating syphilis and the patient breaks out in a rash and fever in the first 2-8 hrs.
Whats the management?
jarisch-herxheimer reaction from killing the spirochete, treat with tylenol
occurs 95% of the time in primary and secondary symphilis
Syphilis
How to follow patients after initiating treatment?
Check titers at 6 and 12 months
Primary and secondary syphilis: expect to see a 4 fold drop (1:16–> 1:4) at 6 months
8-fold drop at 12 months
Early latent syphilis: check titers at 6, 12, 24 months
4-fold drop 12 months
You treat syphilis appropriately, but titers are not decreasing. next steps
check HIV, re-treat, CSF exam
your patient informs you that a previous partner was dx with syphilis within the last 90 days. What do you tell her?
treat her since her exposure was within the last 90 days.
If greater than 90 days, but we don’t have serology on her, then treat her.
