Specialty management differences of syphilis and toxoplasmosis surrounding pregnancy: a prospective cross-sectional study

BACKGROUND: Syphilis and toxoplasmosis are two infectious conditions that can occur during pregnancy. Both these diseases can have ocular manifestations and thus are treated by ophthalmologists and obstetricians. We hypothesized that specialty training would affect the way physicians selected therapy. RESULTS: A total of 209 uveitis specialists and approximately 2500 obstetricians across the USA were surveyed using an online questionnaire distributed via listserv and social media posts. Survey respondents were given a series of clinical vignettes containing case examples of a female patient who was either contemplating pregnancy or in the first trimester and was diagnosed with either syphilis or toxoplasmosis. The questionnaire included a total of four case scenarios with questions relating to the management of these diseases, as well as pregnancy counseling. For the syphilis vignette, a total of 97 physicians responded to the survey questions. Choices of therapy between physician specialty differed significantly (p = 0.0001); however, pregnancy status did not seem to affect therapy choice in syphilis. A total of 96 physicians responded to the survey questions pertaining to the toxoplasmosis vignette. For a non-pregnant patient diagnosed with toxoplasmosis, the differences in therapy choice between specialties were not significant; however, when the patient was pregnant, therapy choice was significantly different between specialties (p = 0.0001). CONCLUSIONS: Differences exist between ophthalmologists and obstetricians concerning the therapy for syphilis and toxoplasmosis during pregnancy. Inter-specialty collaboration is needed to develop consistent criteria to improve the management of these patients.
