Caused by Treponema pallidum
Associated with increased risk of HIV sexual acquisition and transmission
Increased incidence in men who have sex with men
HIV infection may somewhat alter diagnosis, natural history, and management of syphilis, but principles of management are the same with or without HIV infection Syphilis: Epidemiology June 2013 www.aidsetc.org 4<br>

HIV may make clinical lesions more apparent and accelerate progression of syphilis
Primary syphilis
Painless nodule at site of contact, rapidly ulcerates (chancre)
In HIV-infected patients, may see multiple or atypical chancres, or no primary lesion Syphilis: Clinical Manifestations June 2013 www.aidsetc.org 5<br>

Secondary syphilis (2-8 weeks after primary inoculation)
Protean symptoms, may involve almost any organ system and include:
Rash (macular, maculopapular, papulosquamous, or pustular); or condyloma lata
Generalized lymphadenopathy
Constitutional symptoms (fever, malaise, anorexia, arthralgias, headache)
CNS symptoms
Symptoms last days-weeks
In advanced HIV infection, may be more severe or progress more rapidly
Distinguish from primary HIV infection Syphilis: Clinical Manifestations (3) June 2013 www.aidsetc.org 7<br>

Direct detection of T pallidum
Darkfield microscopy of mucocutaneous lesion, DFA-TP, biopsy with silver stain
Presumptive serologic diagnosis tests
Nontreponemal serologic tests (VDRL, RPR)
Treponemal tests (eg, FTA-ABS, TP-PA, EIAs, chemiluminescence immunoassays) Syphilis: Diagnosis June 2013 www.aidsetc.org 11<br>

Testing algorithms:
Traditional: screening for nontreponemal antibodies + confirmation of reactive tests by treponemal assay
Newer: screening with treponemal test (EIA or CIA), with reflex nontreponemal test if positive
May identify previously treated syphilis infection more often than untreated infection
If positive treponemal screening test and negative reflex nontreponemal test: second treponemal test should be done (using different antigens) to confirm
If second treponemal test is positive: assess risk factors and prior syphilis treatment
If suspected primary syphilis: treat empirically, retest with nontreponemal test in several weeks to confirm diagnosis
If no evidence of primary syphilis: treat for late-latent syphilis (unless past treatment can be confirmed)
If second treponemal test is negative: no treatment indicated Syphilis: Diagnosis (2) June 2013 www.aidsetc.org 12<br>

Early-stage disease:
Nontreponemal serologic tests (VDRL, RPR) may show atypical responses (higher, lower, or delayed) in HIV-infected patients
False-negative tests possible (as in HIV-uninfected patients); pursue other diagnostic tests if high suspicion of syphilis (eg, repeat serology, biopsy, DFA of lesion material; exclude prozone phenomenon) Syphilis: Diagnosis (3) June 2013 www.aidsetc.org 13<br>

Neurosyphilis:
All with syphilis (regardless of stage) should be evaluated for clinical evidence of CNS or ocular involvement
CSF exam should be done for any patient with:
Neurologic, auditory, or ophthalmic symptoms or signs
Tertiary syphilis
Treatment failure (on basis of serologic tests)
CSF abnormalities (elevated protein, mononuclear pleocytosis) common in early syphilis and in HIV, without neurologic symptoms: no evidence that clinical and prognostic significance is different in HIV-infected and HIV-uninfected with early syphilis Syphilis: Diagnosis (6) June 2013 www.aidsetc.org 16<br>

Neurosyphilis:
No single test used to diagnose; instead, various combinations of reactive serologic tests, CSF cell count and protein, and reactive CSF-VDRL with or without clinical manifestations support the diagnosis Syphilis: Diagnosis (7) June 2013 www.aidsetc.org 17<br>

18
Neurosyphilis:
CSF examination
Mild mononuclear pleocytosis (6-200 cells/µL), normal or mildly elevated protein
CSF VDRL
Specific; not sensitive (reactive test establishes neurosyphilis; nonreactive test does not exclude it)
CSF FTA-ABS
Highly sensitive; less specific (reactive test does not establish the diagnosis; nonreactive test excludes neurosyphilis)
PCR-based methods not recommended Syphilis: Diagnosis (8) June 2013 www.aidsetc.org 18<br>

Neurosyphilis testing, considerations:
Reactive CSF VDRL plus CSF WBC ≥10 cells/µL supports diagnosis of neurosyphilis
Mild mononuclear CSF pleocytosis (6-15 cells/µL) may be associated with HIV infection itself and may complicate diagnosis of neurosyphilis; using cutoff of >20 cells/µL may improve specificity of neurosyphilis diagnosis in HIV-infected patients
Elevated CSF protein concentration should not be used as sole diagnostic criterion Syphilis: Diagnosis (9) June 2013 www.aidsetc.org 19<br>

20
Risk screening should be routine
Client-centered risk-reduction messages; give specific actions to reduce risk of acquiring STIs and for transmitting HIV
Routine serologic testing for syphilis at least annually; Q 3-6 months if multiple partners, unprotected intercourse, injection drug or methamphetamine use, or partners with risks
Consider referral for behavioral intervention
Evaluate for other STIs Syphilis: Preventing Exposure June 2013 www.aidsetc.org 20<br>

For persons exposed sexually to someone with syphilis: evaluate clinically and serologically and treat presumptively
Persons exposed within the 90 days preceding diagnosis of primary, secondary, or early-latent syphilis in a sex partner may be infected even if tests are seronegative: treat presumptively
Persons exposed >90 days before diagnosis of primary, secondary, or early-latent syphilis in a sex partner: treat presumptively if serologic test results are not available immediately and follow-up is uncertain Syphilis: Preventing Disease June 2013 www.aidsetc.org 21<br>

22
Management similar to that for HIV-uninfected persons, but rates of serologic treatment failure and neurologic complications may be higher in HIV infection; closer follow-up is recommended
Penicillin is treatment of choice
Patients with penicillin allergy whose compliance or follow-up cannot be ensured: desensitize and treat with penicillin
Use alternatives to penicillin only with close clinical and serologic monitoring
Azithromycin resistance and treatment failure; especially in men who have sex with men (MSM) Syphilis: Treatment June 2013 www.aidsetc.org 22<br>

No special considerations, no evidence that ART should be delayed until after treatment for syphilis
IRIS is uncommon
Use of ART associated with:
Decreased risk of serologic failure of syphilis treatment
Lower risk of neurosyphilis
Normalization of CSF parameters after treatment Syphilis: Starting ART June 2013 www.aidsetc.org 26<br>

Monitor clinical and serologic response to treatment; assure at least 4-fold decline from titer done at time of treatment:
Early stage: at 3, 6, 9, 12, 24 months
Late-latent: at 6, 12, 18, 24 months
Consider treatment failure: persistence or recurrence in clinical signs and symptoms or sustained 4-fold increase in nontreponemal test titer
Neurosyphilis: if CSF pleocytosis present initially, repeat CSF exam at 6 months; also repeat if symptoms recur or nontreponemal titer increases by 4-fold
Consider retreatment if no decrease in CSF WBC by 6 months or if WBC not normal by 2 years Syphilis: Monitoring and Adverse Events June 2013 www.aidsetc.org 27<br>

After successful treatment, nontreponemal tests may remain “serofast,” ie, reactive at stable titer, usually low (≤1:8)
Sustained ≥4-fold increase in titer indicates reinfection Syphilis: Monitoring and Adverse Events (2) June 2013 www.aidsetc.org 28<br>

Use penicillin, if possible, as in nonpregnant HIV-infected adults
Penicillin is effective for preventing syphilis transmission to the fetus and for treatment of fetal infection
Optimal penicillin regimen is not clear
In early syphilis, consider second injection of benzathine penicillin G 1 week after first dose
No alternatives to penicillin proven effective and safe for treatment of syphilis during pregnancy or prevention of fetal infection
Pregnant women with syphilis and history of penicillin allergy should undergo desensitization and treatment with penicillin Syphilis: Considerations in Pregnancy (2) June 2013 www.aidsetc.org 36<br>

Jarisch-Herxheimer reaction in 2nd half of pregnancy may precipitate preterm labor or fetal distress
In 2nd half of pregnancy, sonographic evaluation for fetal or placental syphilis
Consult with OB specialists
After treatment, repeat serologic titers in 3rd trimester and at delivery
Insufficient data on serologic responses after therapy
Treatment likely inadequate if delivery ≤30 days of treatment, if woman has sign of infection at delivery, or if maternal titer is 4-fold higher than pretreatment titer Syphilis: Considerations in Pregnancy (3) June 2013 www.aidsetc.org 37<br>
