ABSTRACT

Involvement of the cardiovascular system in patients with infectious and parasitic diseases can result from both intrinsic mechanisms of the disease and drug intervention. Malaria is an example, considering that the endothelial injury by Plasmodium-infected erythrocytes can cause circulatory disorders. This is a literature review aimed at discussing the relationship between malaria and endothelial impairment, especially its effects on the cardiovascular system. We discuss the implications of endothelial aggression and the interdisciplinarity that should guide the malaria patient care, whose acute infection can contribute to precipitate or aggravate a preexisting heart disease.


O acometimento do sistema cardiovascular em pacientes com doenças infecciosas e parasitárias pode ocorrer tanto por mecanismos intrínsecos à doença como em decorrência de intervenção medicamentosa. A malária é uma dessas doenças, tendo em vista que a agressão endotelial generalizada que se observa na infecção por Plasmodium pode causar distúrbios circulatórios. O objetivo deste artigo é discutir a relação entre malária e o comprometimento endotelial, em especial suas consequências sobre o sistema cardiovascular, a partir de uma revisão da literatura. Discutem-se as repercussões da agressão endotelial, bem como a interdisciplinaridade que deve nortear a atenção ao paciente malárico cuja infecção aguda pode contribuir para precipitar ou agravar doença cardíaca preexistente.

ABSTRACT

La toxocariasis es una infección parasitaria producida por un helminto que en el ser humano no alcanza su estadio adulto. El hombre es para sus especies, Toxocara canis y Toxocara cati, un hospedador paraténico. Dicha infección puede producir el síndrome de larva migrans visceral, el síndrome de larva migrans ocular y la toxocariasis inaparente. En el síndrome de larva migrans visceral el compromiso de órganos puede incluir hígado, pulmón, piel, sistema nervioso, musculoesquelético, riñón y corazón. Sobre este último, cada vez se reconoce más la importancia que pueden tener las manifestaciones cardiovasculares de la toxocariasis y la relevancia clínica de considerarlas. En el presente artículo, haciendo una búsqueda sistemática de información, se revisan los principales aspectos clinicopatológicos de las manifestaciones cardiovasculares de la toxocariasis incluyendo su fisiopatología, hallazgos de laboratorio, diagnóstico y opciones terapéuticas, con el objeto de llamar la atención acerca de la importancia de esta zoonosis y su relevancia para la medicina cardiovascular en adultos y en niños.


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 toxoca-riasis. 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.
