ABSTRACT

Introducción: El nuevo coronavirus tiene material genético. Esto permite a un receptor transformarse en el sitio de acción polibásica y es capaz de infectar a través de múltiples receptores de entrada y resaltar a las proteínas de tipo espiga (S). La proteína 'espiga' es una proteína de fusión viral de la Covid-19, es por ello que en la búsqueda terapéutica se establece las siguientes preguntas, ¿la hibridación de anticuerpos logrará ganar la guerra contra la pandemia de la Covid-19?; o ¿el plasma rico en anticuerpos puede mantener a las personas fuera de las unidades de cuidados intensivos? Estas preguntas radican en que los estudios actuales no establecen la verdadera utilidad de la terapia inmunológica. Objetivo: Presentar la utilidad de anticuerpos híbridos ante la actual pandemia de la Covid-19 y otros coronavirus. Métodos: Se desarrolló una revisión bibliográfica a partir de la evidencia existente acerca del panorama de la proteómica en el estudio del sistema inmune para combatir infecciones. Se utilizó un margen de tiempo entre el año 1999 al 2020. Se seleccionaron un total de 37 documentos que cumplen con los protocolos de inclusión en idioma inglés o español; en la búsqueda se utilizaron términos MeSH. Se escogieron estudios de orden observacional o analíticos; de carácter experimental, reporte de casos que dataran aspectos bioquímicos, biológicos, patológicos y clínicos del sistema inmune como blanco terapéutico ante la pandemia actual. El análisis documental fue realizado por el Grupo de Investigación en Salud de la Universidad del Cauca-Popayán, con apoyo y dirección de la Universidad de Houston, Texas (EEUU), con el apoyo de profesorado del Programa de Investigación Humana de la NASA. Resultados: La respuesta positiva para controlar esta pandemia está basada en los cuidados preventivos y en las posibles terapias innovadoras ante los nuevos coronavirus que logren transmitirse de animales a humanos. Se resalta el posible uso de anticuerpos de dominio único híbridos para frenar infecciones víricas nuevas. Conclusiones: Se resalta el posible uso de anticuerpos de dominio único híbridos para frenar infecciones víricas nuevas(AU)


Introduction: The new coronavirus has genetic material. This allows a receptor to transform into the polybasic site of action and it is capable of infecting through multiple entry receptors and highlighting spike-like (S) proteins. The spike protein is a viral fusion protein of Covid-19, which is why in the therapeutic search the following questions are established, will antibody hybridization succeed in winning the war against the Covid-19 pandemic? Or can antibody-rich plasma keep people out of intensive care units? These questions are that current studies do not establish the true utility of immune therapy. Objective: To settle the usefulness of hybrid antibodies to the current Covid-19 pandemic and other coronaviruses. Methods: A bibliographic review was developed from the existing evidence about the panorama of proteomics in the study of the immune system to fight infections. A time frame was used between 1999 and 2020. A total of 37 documents, in English or Spanish, that comply with the inclusion protocols were selected; MeSH terms were used in the search. Observational or analytical studies were chosen; experimental, case report dating biochemical, biological, pathological and clinical aspects of the immune system as a therapeutic target in the current pandemic. The documentary analysis was carried out by the Health Research Group of the Universidad del Cauca-Popayán, with the support and direction of the University of Houston, Texas (USA), with the support of faculty from NASA Human Research Program. Results: The positive response to control this pandemic is based on preventive care and possible innovative therapies for the new coronaviruses that manage to be transmitted from animals to humans. Conclusions: The possible use of hybrid single domain antibodies to stop new viral infections is highlighted(AU)

ABSTRACT

O presente artigo busca informar o médico generalista sobre os aspectos clínicos da infecção causada pelo vírus varicela zoster. O autor cita o comportamento viral de inatividade nos gânglios das raízes dorsais e as causas prováveis para sua reativação, tais como idade avançada, ou extremamente precoce, doenças do sistema imunológico e determinados tumores entre outras circunstâncias, que são capazes de propiciar condições para a reinfecção conhecida como herpes zoster, cujas características clínicas são também apresentadas, bem como seu diagnóstico e tratamento. As complicações neurológicas relacionadas à infecção pelo vírus varicela zoster são estudadas no artigo. É feita, ainda, a conceituação da neuralgia pós-herpética, e a atualização da abordagem terapêutica deste tipo de dor neuropática. São estudados os vários fatores fisiopatológicos responsáveis por sua gênese, cujo conhecimento fundamenta o tratamento medicamentoso eficiente.


The aim of the present article is to inform the internist on the clinical aspects of the varicella zoster virus infection. The author refers the viral inactivity behavior, harbored in the dorsal root ganglia. The probable causes to its reactivation are mentioned, such as advanced or very precocious age, immunocompromised states and some tumors among other circunstances. These conditions are capable to create the right enviromnent to the reinfection, called herpes zoster, whose clinical aspects, diagnosis and treatment are presented. The neurological complications related to the Varicella Zoster Virus infection are studied in the article. The post herpetic neuralgia is defined as a specific type of naturopathic pain. The author brings up to date the therapeutical approach of the painful condition caused by herpes zoster and emphasizes the significance of understanding the post herpetic neuralgia pathophysiologic mechanisms to its effective treatment.
