Toxocara canis: migración larval y eosinofilia en el hospedador paraténico

Toxocariasis is a parasitic infection produced by helminths that cannot reach their adult stage in humans. For their etiological species (Toxocara canis and Toxocara cati), man is a paratenic host. Infection by such helminths can produce a variety of clinical manifestations, such as: visceral larvae migrans syndrome, ocular larvae migrans syndrome and covert toxocariasis. In the visceral larvae migrans syndrome, the organs that are mainly involved include liver, lungs, skin, nervous system, muscles, kidneys and the heart. Regarding the latter, the importance of cardiovascular manifestations in toxocariasis, as well as its clinical relevance, has increasingly begun to be recognized. The current article is based on a systematic information search, focused mainly on the clinical and pathological aspects of cardiovascular manifestations in toxocariasis, including its pathophysiology, laboratory findings, diagnosis and therapeutical options, with the objective of highlighting its importance as a zoonosis and its relevance to the fields of cardiovascular medicine in adults and children.

RESUMENSe determinó la frecuencia de serorreactores y riesgo de exposición a Toxocara canis en el personal que laboraba en clínicas y consultorios veterinarios de la ciudad de Lima. Se consideró un grupo expuesto, en contacto directo con canes (n=135) y un grupo no expuesto, de personal administrativo (n=108). Los sueros fueron evaluados mediante una prueba de ELISA con antígenos de excreción / secreción de larvas L2 de T. canis, en diluciones de 1/200, 1/400, 1/800, 1/1600 y más de 1/1600, en búsqueda de anticuerpos IgG. En el grupo expuesto, el 95.6, 58.5, 37.0, 23.7 y 9.6% resultaron positivos en las diluciones indicadas, respectivamente, en tanto que en el grupo no expuesto se encontró el 97.2, 50.0, 32.4, 17.6 y 3.7%, respectivamente. No se encontró asociación entre la proporción de positivos y los grupos de exposición. Se concluye que la práctica profesional no representa un factor de riesgo para la presentación de infecciones humanas a T. canis. Palabras clave: toxocariasis, T. canis, médicos veterinarios, clínicas ABSTRACTThe frequency of seropositives and risk of exposure to Toxocara canis in the personnel working in veterinary clinics in the city of Lima was determined. An exposed group with direct contact to dogs (n=135) and a non-exposed group of administrative staff (n=108) were evaluated. Sera samples were analyzed by ELISA test using excretion/ secretion antigens of L2 larvi of T. canis in dilutions of 1/200,
