GUERRERO, Amanda et al. Toxoplasmosis in pregnancy: Epidemiological, clinical and laboratory characteristics in a reference center. Rev. Inst. Med. Trop. [online]. 2023, vol.18, n.1, pp.12-20. ISSN 1996-3696.

Toxoplasmosis is a zoonosis caused by the protozoan Toxoplasma gondii (T. gondii), with a great impact on fetal health when acquired during pregnancy, due to the risk of vertical transmission. It can produce clinical manifestations in newborns: chorioretinitis, hydrocephalus, calcifications and psychomotor retardation. Early detection and the establishment of adequate therapy are key to avoiding complications associated with fetal-maternal transmission. Objective: To describe the clinical characteristics of pregnant women diagnosed with toxoplasmosis and their newborns, during the years 2018 to 2021 who attended the Infectious Diseases Service of the Social Welfare Institute (IPS). Materials and methods: Observational, descriptive, cross-sectional study, using a data registry of pregnant patients who attended the IPS during the years 2018 to 2021. Results: 62 pregnant women were included; median age 30 years, (21-44 years); 4 (6%) pregnant women had their first consultation in the first trimester, 39 (63%) in the second and 19 (31%) in the third trimester. 9 (15%) patients were classified as having seroconversion, and 53 (85%) with suspected acute infection. 55 patients underwent amniocentesis; 26 (47%) had detectable PCR results for Toxoplasma gondii in amniotic fluid, and 29 (53%) undetectable. Only 19 newborns had serology tests for the diagnosis of congenital toxoplasmosis. Among the fetal complications were macrocephaly, and newborn jaundice.
