Treatment for Syphilis in a 62-year-old Diabetic Patient with Breast Abscess and Positive VDRL Test
For a 62-year-old diabetic patient with uncontrolled diabetes, recent breast abscess, and a positive VDRL test of 1:80, the recommended treatment is parenteral penicillin G, with the specific regimen determined by the stage of syphilis. 1
Diagnostic Considerations
- The positive VDRL test of 1:80 indicates active syphilis infection, but this nontreponemal test should be confirmed with a treponemal test (FTA-ABS or TP-PA) for complete diagnosis 2
- Both nontreponemal and treponemal tests are necessary for accurate diagnosis, as using only one type of test is insufficient 2, 1
- The high VDRL titer (1:80) suggests active infection, as nontreponemal test titers correlate with disease activity 3
- The stage of syphilis (primary, secondary, latent, or tertiary) must be determined through clinical evaluation to guide appropriate treatment duration 3, 1
Treatment Recommendations
- Parenteral penicillin G is the preferred drug for all stages of syphilis 3, 1
- For early syphilis (primary, secondary, or early latent syphilis of less than one year's duration):
- Benzathine penicillin G 2.4 million units IM in a single dose 1
- For late latent syphilis (more than one year's duration) or latent syphilis of unknown duration:
- Benzathine penicillin G 2.4 million units IM once weekly for three consecutive weeks 1
- For tertiary syphilis or neurosyphilis:
- Aqueous crystalline penicillin G 18-24 million units daily, administered as 3-4 million units IV every 4 hours for 10-14 days 1
Special Considerations for This Patient
- The patient's uncontrolled diabetes requires attention as it may:
- The recent breast abscess is likely related to the uncontrolled diabetes, as there is a strong association between diabetes and breast abscesses in nonlactating women 5, 7
- Diabetic patients with breast abscesses typically have:
Monitoring and Follow-up
- Clinical and serological evaluation should be performed at 6 and 12 months after treatment 1
- A fourfold decline (2 dilutions) in VDRL titer indicates adequate treatment response 2, 1
- Persistent or recurrent signs/symptoms, or a sustained fourfold increase in titer, should prompt evaluation for treatment failure or reinfection 1
- Diabetic control should be optimized during and after treatment to improve outcomes 5, 7
- The breast abscess should be managed appropriately with incision and drainage if needed, along with appropriate antibiotics 7
Common Pitfalls and Considerations
- Failure to confirm the VDRL result with a treponemal test may lead to misdiagnosis 2
- Inadequate treatment duration based on incorrect staging of syphilis 3
- Overlooking the need for neurosyphilis evaluation in patients with high VDRL titers, especially with uncontrolled diabetes 8
- Neglecting diabetic control during treatment, which may compromise outcomes 5
- Inadequate follow-up of serological response to treatment 1
