Assessment of the Value of Rescreening for Syphilis in the Third Trimester of Pregnancy

摘要

Objectives. Our aim is evaluating the need for repeatingtests for syphilis on pregnant women in the third trimester.Study design. A single-center retrospective cohort studywas performed on all women delivering 7/03–6/04.Results. During the study interval, 2244 women deliveredat our hospital. Of those women having available records andattending at least one prenatal visit, 1940 (98.9%) werescreened for syphilis at the first prenatal visit. Of the 1627women beginning prenatal care prior to 27 weeks and deliveringafter 32 weeks, 1377 (84.6%) were rescreened in the thirdtrimester. No cases of syphilis were identified with either theinitial (upper limit of 95% CI 0.24%) or repeat (upperlimit of 95% CI 0.34%) screening. Conclusions. Inour obstetric population, syphilis is so uncommon that mandatedprenatal screening on more than one occasion seemsunjustified and laws requiring repeated screening shouldbe reevaluated.
