[Management of Toxoplasmic Seroconversion in the Third Trimester of Pregnancy in Tunisia].

The purpose of our study was to report the particularities of the management of toxoplasmosis seroconversion cases occurred during the third trimester of pregnancy and diagnosed in the Institute Pasteur of Tunis. The study was conducted in the Laboratory of Parasitology-Mycology of the Institute Pasteur of Tunis between January 2005 and December 2017. A total of 27 cases of toxoplasmosis seroconversion during the third trimester were included. Prenatal diagnosis was performed in five cases. PCR was positive in one case. Pyrimethamine-sulfadoxine was prescribed in one case with positive PCR and in another case as soon as maternal infection was confirmed. Spiramycine was prescribed in 24 cases for the duration of the pregnancy. One woman did not take any treatment because seroconversion was diagnosed just before delivery. Twenty newborns had congenital toxoplasmosis: 19 cases were diagnosed by serology and one case was diagnosed after amniocentesis. Two newborns (10%) were symptomatic at birth. All the newborns had neither clinical nor radiological signs during the follow-up.
