CM. Pregnancy as a risk factor to disease and the vertical transmission to the fetus, of a host of parasitic ailments

This article is a tour de force that reviews all the perils of pregnant women exposed to a myriad of parasites from our tropical regions in Latin America. The authors guide us to a host of conditions that favor numerous ailments of the most vulnerable population of our region, subjected as they are, to unhealthy environments and common parasites from protozoan to worms, that may invade and populate pregnant women, as well as their offspring. Through this extensive and terrifying tale, the readers will encounter all possible points of parasite entry, as well as the barriers, that may prevent such risks and vertical transmission to occur, from the whole body of the mother to the placenta and the fetus. The authors, not only describe the pathophysiology of the many instances and social conditions where a parasite infection may happen to a pregnant mother, in need of help and protection, but they also go the long way to explain in excruciating detail, all the available protocols of treatment to such diseases, as well as the necessary measures of prevention at a population scale. This warning and advice comes at a timely occasion of this humanitarian crisis, aggravated by Covid-19. The information comes from the best source of medical and science experts of this field, our premier institute of the Central University of Venezuela, The Institute of Tropical Medicine.

  1. Arturo J Martí-Carvajal

    Señor editor: reciba mi más sentida palabra de felicitación por este nuevo artículo. El tema es un problema de salud pública que abre un sin fin de potenciales estudios de la parasitología en la mujer embarazada. Las autoras han realizado un enjundioso trabajo, fácil de leer y comprender sobre la interacción embarazada, feto y parásito. Ellas son valiosas, no por ser mujeres, sino porque demuestran que su condición biológica no tiene nada que ver con el elevado nivel de formación intelectual. ¿Quién en Venezuela desconoce la biografía de la Dra. Ruíz? Esa resiliencia la llevó a un sitial de honor, debemos sentirnos satisfechos por los logros de sendas investigadoras de primer nivel. Son nuestras Maríe Curie. Les felicito, así como al Dr. Rangel-Aldao porque les abrió una ventana para que el mundo científico venezolano y extranjero se enteren que, a pesar de nuestra anomia, aquí sí se puede, de existir voluntad para no publicar doxa, sino logo de primer mundo. Esa episteme es eso que los primeros griegos decían: conocimiento. Ellas están en el extremo derecho de la Alegoría de la Línea y están fuera de la Caverna: iluminando con la luz de la verdad. Son virtuosas.

    1. Academia Nacional de Medicina

      Muchas gracias, Dr. Martí Carvajal, por ese reconocimiento a quienes son, realmente, nuestros héroes anónimos, científicos y médicos de una preparación formidable y distinguida trayectoria asistencial, que en forma silenciosa trabajan día a día por la salud, producción de conocimiento y educación avanzada en nuestro país. Apreciamos mucho su nobleza por este gesto.

  2. Excelente lección sobre medicina tropical complementada con la impronta y la experiencia propia en algunos de los tópicos reflejados en tan interesante artículo. Raramente vemos en la literatura un coordinado multi-análisis sobre patógenos que amenazan poblaciones desfavorecidas y mucho menos relacionando su efecto sobre el ser más importante del conglomerado humano, la mujer en gestación.
    Felicitaciones a las distinguidas autoras y al editor por su tino en su escogencia.
