Syphilis: Follow-up
Updated: Jul 17, 2009
Follow-up
Further Outpatient Care
- Patients treated for primary and secondary syphilis should have follow-up VDRL at 3, 6, and 12 months after treatment. Patients with HIV should be monitored closely, as they are known to have more rapid progression of disease.
- Most patients with primary syphilis who are treated adequately have a nonreactive VDRL within 1 year, and almost all patients treated for secondary syphilis have a negative VDRL result within 2 years.
- A small minority of patients remain seropositive in spite of successful treatment.
- Therapy is considered a failure if the signs and symptoms of syphilis return.
- This occurs when the titer of the nontreponemal test increases 4-fold or a 4-fold decrease from the initial VDRL titer does not occur within 1 year.
- Patients with neurosyphilis should have follow-up at 6-month intervals for at least 3 years with physical examinations and CSF and serologic testing.
- Pregnant women treated for syphilis should have monthly VDRL testing for the duration of their pregnancy.
Deterrence/Prevention
- Safe sex practices
- Use of condoms
- Partner testing
- Prenatal testing
Complications
- Cardiovascular disease
- CNS disease
- Membranous glomerulonephritis
- Paroxysmal cold hemoglobinemia
- Irreversible end-organ damage
- Jarisch-Herxheimer reaction
Prognosis
- The prognosis in treated primary and secondary syphilis is excellent. T pallidum remains highly responsive to the penicillins and cure is likely.
- The prognosis in tertiary syphilis is less sanguine, although a significant number of patients demonstrate cure with antibiotic therapy.
Patient Education
- As with all STDs, patient education must stress the importance of safer sexual practices and the need for prompt medical evaluation of chancres and other symptoms of STDs. All patients diagnosed with an STD should be screened for HIV.
- For excellent patient education resources, visit eMedicine's Sexually Transmitted Diseases Center and Pregnancy and Reproduction Center. Also, see eMedicine's patient education articles Sexually Transmitted Diseases, Syphilis, Birth Control Overview, and Birth Control FAQs.
Miscellaneous
Medicolegal Pitfalls
- Failure to conduct testing for syphilis because the lesion or rash is suggestive of another entity is the major potential pitfall in patients with syphilis.
- Given the ability of syphilis to masquerade as a number of illnesses, routine serologic testing for syphilis is prudent when rendering a diagnosis of pityriasis rosea or another generalized rash. Similar logic applies to genital lesions.
- If the alternative diagnosis is an STD, such as chancroid, good medical care includes testing for syphilis.
- Regardless of the symptoms, testing for coexisting syphilis is recommended when diagnosing other STDs, such as urethritis or cervicitis. An increase in attention to this issue in women with suspected STDs is needed.
Special Concerns
- Pregnancy
- The penicillin regimen appropriate to the stage of disease is the only treatment recommended.
- Do not administer tetracycline or doxycycline during pregnancy.
