    Immunopathogenesis of Orthopoxviridae: insights into immunology from smallpox to monkeypox (mpox)

    Get PDF
    Since 2019, notable global viral outbreaks have occurred necessitating further research and healthcare system investigations. Following the coronavirus disease 2019 (COVID-19) pandemic, in 2022, whilst severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains evolved, monkeypox virus (MPXV) infections became more evident. MPXV is of the Orthopoxviridae genus, belonging to the family Poxviridae. Zoonotic transmission (animal-to-human transmission) may occur. The Orthopoxviridae genus includes other orthopoxviruses (OPXVs) present in animal host reservoirs that include cowpox viruses (CPXVs), vaccinia virus (VACV), and variola virus (VARV), with the latter being a causal agent of smallpox and excessive mortality. This review aims to present facts about MPXV-specific pathogenesis, epidemiology, and immunology alongside historical perspectives. MPXV was rarely reported outside Africa before April 2000. Early research since 1796 contributed towards the eradication of VARV leading to immunisation strategies. The World Health Organisation (WHO) announcement that VARV had been eradicated was confirmed in 1980. On the 23rd of July 2022, the WHO announced MPXV as a health emergency. Therefore, concern due to the propagation of MPXV causing monkeypox (mpox) disease requires clarity. Infected hosts display symptoms like extensive cellular-initiated rashes and lesions. Infection with MPXV makes it difficult to differentiate from other diseases or skin conditions. Antiviral therapeutic drugs were typically prescribed for smallpox and mpox disease; however, the molecular and immunological mechanisms with cellular changes remain of interest. Furthermore, no official authorized treatment exists for mpox disease. Some humans across the globe may be considered at risk. Historically, presenting symptoms of mpox resemble other viral diseases. Symptoms include rashes or lesions like Streptococcus, but also human herpes viruses (HHVs), including Varicella zoster virus (VZV)

    Introduction: Inflammation is a homeostatic response of the body. It is one of the main reasons for consultation in Cuba and throughout world. There is a misperception that it is an isolated and always pathological entity. It is a dynamic, complex, systemic, and multifactorial process. Therefore, it is a challenge to elucidate the elements and the tissue changes that it causes to establish the best way to improve the clinical practice related to an inflammatory process.Objective: To describe inflammation, its classification, elements involved, and systemic changes from an immunological perspective.Material and Methods: A review of the topic was made using the updated bibliography. Free-access articles were consulted in Pubmed and Scielo databases in the period from January 2013 to December 2018.Development: Inflammation can be classified according to the damage, time or effectors involved. 聽The main molecules are the cytokines like TNF-伪, IFN-纬, IL-1尾, IL-10, IL-6, TGF-尾. Some cells participate such as neutrophils, mastocytes, macrophages, T-lymphocyes, and the vascular endothelium.聽 During the inflammatory process, the functions of almost all organ systems are modified. It produces systemic changes that are observed in physiological processes such as pregnancy or aging. Sometimes inflammation triggers diseases such as cardiovascular and neurological ones, and cancer. The pathophysiological mechanisms have not been clarified.Conclusions: Currently, the events that trigger chronic inflammation and how tissue damage occurs are unknown. The biggest challenge is to elucidate the causes and immunological mechanisms that lead to inflammatory manifestations that are expressed as systemic neurological, cardiovascular and autoimmune diseases, among others.Keywords: Acute inflammation, chronic inflammation, proinflammatory mediators, sepsis.Introducci贸n: La inflamaci贸n es una respuesta homeost谩tica del organismo. Es uno de los principales motivos de consulta en Cuba y el mundo. Existe una percepci贸n err贸nea de que es una entidad aislada y siempre patol贸gica. Es un proceso din谩mico, complejo, sist茅mico y multifactorial. Por eso constituye un reto el dilucidar los elementos, cambios tisulares que causa y c贸mo proceder en la cl铆nica ante un cuadro inflamatorio.Objetivo: Describir la inflamaci贸n, su clasificaci贸n, elementos involucrados y cambios sist茅micos desde una perspectiva inmunol贸gica.Material y M茅todos: Se realiz贸 una revisi贸n sobre el tema empleando la bibliograf铆a actualizada y luego se consultaron art铆culos de libre acceso en las bases de datos Pubmed y Scielo en el per铆odo de enero de 2013 a diciembre de 2018.Desarrollo: La inflamaci贸n puede clasificarse seg煤n el da帽o, tiempo o los efectores involucrados. Las principales mol茅culas son las citocinas como TNF-伪, IFN-纬, IL-1尾, IL-10, IL-6, TGF-尾. Participan c茅lulas como los neutr贸filos, mastocitos, macr贸fagos, linfocitos T y las del endotelio vascular. Durante el proceso inflamatorio se modifican las funciones de casi todos los sistemas de 贸rganos. En ciertos tipos de inflamaci贸n, es la respuesta adaptativa quien origina y perpet煤a el proceso inflamatorio.Conclusiones: En la actualidad se desconocen los acontecimientos que desencadenan inflamaci贸n cr贸nica y c贸mo ocurre el da帽o tisular. El mayor desaf铆o consiste en dilucidar las causas y mecanismos inmunol贸gicos que conllevan a las manifestaciones inflamatorias sist茅micas que se manifiestan como enfermedades neurol贸gicas, cardiovasculares y autoinmunes, entre otras.Palabras claves: Inflamaci贸n aguda, inflamaci贸n cr贸nica, mediadores proinflamatorios, sepsis

    The complement system is activated in three pathways: classical, alternative and lectins. The lest one belongs to the innate immune system and it is the oldest in the phylogeny is still under descovering. It is vital in the defense against numerous microorganisms, but sometimes its activation produces inflammatory processes harmful to the host that cause many diseases such as some rheumatic disorders.El sistema del complemento se activa por tres v铆as: cl谩sica, alternativa y la de las lectinas. Esta 煤ltima que pertenece al sistema inmune innato y es la m谩s antigua en la filogenia pero a煤n est谩 en un proceso de esclarecimiento de su cascada definitiva.

    Introduction: Neurological manifestations associated to dengue virus are being reported more frequently.Objective:To identify the neuroimmune response evaluated by Reibergram in patients with neurological manifestations because of dengue virus.Material and methods: The highest levels of immunoglobulin and albumin were quantified in serum and the cerebrospinal fluid in six adult patients with neurological manifestations of dengue. Q function was calculated with the concentration values in serum and cerebrospinal fluid of these analytes. Values of immunoglobulin Q vs Q albumin were introduced in the specific Reibergrams for each immunoglobulin. Albumin was used as a marker for the evaluation of blood-cerebrospinal fluid barrier.Results:Reibergram allowed to establish the incidence of intrathecal synthesis of higher immunoglobulins (three types of patterns) in both the postinfectious and parainfectious neurological manifestations, except a patient who developed Guillain-Barre Syndrome.聽 It also allowed to evaluate the blood-cerebrospinal fluid barrier in each patient.Conclusions:The use of Reibergram is important in the assessment of the immune response in patients with neurological manifestations of dengue virus.Keywords: neurological complications, dengue, Reibergram, Guillain-Barre Syndrome, acute disseminated encephalomyelitis, encephalitis.Introducci贸n: Las manifestaciones neurol贸gicas asociadas al virus del dengue est谩n siendo m谩s frecuentemente reportadas.Objetivo: Identificar la respuesta neuroinmunol贸gica, evaluada por Reibergrama, en pacientes con manifestaciones neurol贸gicas por virus del dengue.Material y m茅todos: Se cuantificaron en suero y l铆quido cefalorraqu铆deo los niveles de inmunoglobulinas mayores y alb煤mina en seis pacientes adultos con manifestaciones neurol贸gicas por dengue.
