Resumen

BRIZUELA, Martín et al. Congenital toxoplasmosis in twins: case report. Rev. chil. infectol. [online]. 2020, vol.37, n.3, pp.316-321. ISSN 0716-1018.  http://dx.doi.org/10.4067/s0716-10182020000300316.

Congenital toxoplasmosis in twin pregnancies is infrequent. We present the case of a monozygotic and monocorial twin pregnancy with maternal toxoplasmosis infection diagnosed at 33 weeks gestation by detecting reactive IgM and IgG and low avidity test for IgG. The detection of the parasite in amniotic fluid could not be performed because the amniocentesis was not done. The term newborns presented cerebral calcifications and bilateral active chorioretinitis without other associated clinical manifestations. They had IgG and IgM reactive for toxoplasmosis. The detection of Toxoplasma gondii was not performed by placental PCR or cord blood. They received treatment during the first year of life with pyrimethamine, sulfadiazine and folinic acid. They had no adverse events associated with the therapy. The diagnostic assessment and treatment does not differ from pregnancies with a single fetus. One or both newborns may be compromised. Multidisciplinary monitoring is essential for the early detection of reactivations or progression of lesions.
