Congenital toxoplasmosis: The importance of adherence to guidelines and clinical implications in Colombia

Background: Congenital toxoplasmosis continues to be a public health problem. Although clinical guidelines have been divulgated and are well known, they are not implemented in some health institutions, in addition of an inappropriate interpretation of the serological tests in pregnant women. This situation can lead to lack of screening and treatment in pregnant women with primary Toxoplasma gondii infection. Case reports: We report two cases of congenital toxoplasmosis, one with a fatal outcome. In both cases, the clinical guidelines were not initially followed, leading to a delayed diagnosis and, consequently, an inappropriate management in conditions with severe damage. Conclusions: Toxoplasmosis is a congenital infection still prevalent in some countries, with severe sequelae, neurological disability, and even late risk of ocular damage. Additionally, some varieties of the T. gondii strains have a more aggressive pattern in Latin America, worsening the clinical presentation of cases and including a high risk of death.
