[Syphilis and pregnancy].
OBJECTIVE
The aim of our study was to assess the impact of maternal syphilis on pregnancy and foetal/neonatal outcomes.


METHODS
A retrospective study, conducted from 1 June 1992 to 31 December 2004, involved 85 seropositive pregnant women at the West Guyanese hospital in French Guyana. Inclusion criterias were a positive treponemal pallidum hemagglutination assay (TPHA) with a titre greater or equal to than 1/2560 and a positive Venereal Disease Research Laboratory (VDRL) with a titre greater or equal to than 1/16 for a pregnant woman with different stages of pregnancy. We evaluated maternal characteristics, antenatal care, type of treatment, the presence of coinfections, fetal ultrasound characteristics, outcome of pregnancy, umbilical cord biological diagnosis and neonatal clinical exams. We evaluated the efficiency of early and complete syphilis treatment in the prevention of vertical infection.


RESULTS
The proportion of seropositive pregnant women with lack or inadequate antenatal care was high (40%), hence, the diagnosis and treatment were performed late in pregnancy. The incidences of adverse obstetric outcomes were the following: perinatal deaths (20%), stillbirths (12,9%), preterm deliveries (18,8%) and low birth weight (28,2%). Specific ultrasound findings of congenital syphilis (stillbirth excluded) were found in six cases out of 61 (9,8%) and specific neonatal clinical features of early congenital syphilis were found in four cases. There is a high correlation demonstrated between vertical infections and late or inadequate syphilis treatment in a pregnant woman.


CONCLUSIONS
Antepartum syphilis represents a health problem in developing countries and tends to reappear in developed countries. All pregnant women should receive an adequate prenatal care including obligatory screening test for syphilis, we should keep in mind the possibility of syphilitic infection in case of maternal clinical features or foetal signs especially hepatosplenomegaly, hydrops fetalis or intestinal hyperechogenicity.
