Primary Institution: University of Texas Health Science Center
Hypothesis
The study aims to assess the effect of several maternal variables on the serologic response following the treatment of syphilis in pregnancy.
Conclusion
An absence of a history of syphilis and a high initial RPR titer are predictive of a positive response following treatment.
Supporting Evidence
- Patients without a prior history of syphilis were more likely to have a positive treatment response.
- Patients with a high initial RPR titer had a significantly higher likelihood of a positive response.
- Only 55% of observations at 3 months showed a positive response, indicating potential undertreatment.
Takeaway
If pregnant women have never had syphilis before and have a high initial titer, they are more likely to respond well to treatment.
Methodology
A retrospective chart review over 5 years identified patients with serologically confirmed syphilis who received complete treatment and had follow-up RPR titers.
Potential Biases
Potential retrospective bias due to reliance on accurate documentation of staging and treatment.
Limitations
The study was limited by the small number of eligible patients and reliance on chart documentation, which may lead to misclassification.
