ABSTRACT

La enfermedad de Behçet es una vasculitis crónica, multisistémica y autoinmune caracterizada por una tríada de signos claves presentes en los pacientes que la padecen. Se presenta una paciente femenina, caucásica, de 16 años, con cefalea, mareos y paresia en hemicuerpo izquierdo que, tras examen físico y métodos complementarios, se diagnosticó como enfermedad de Behçet con manifestaciones neurológicas (neurobehçet), y a la que se impuso tratamiento, con buena respuesta. Se cuantificó IgG, IgA, IgM y albúmina en suero y LCR, por inmunodifusión radial simple, encontrándose síntesis intratecal de las 3 clases de inmunoglobulinas mayores. Los hallazgos en este caso constituyen el primer estudio donde se utiliza el reibergrama para evaluar la respuesta neuroinmunológica en un paciente con enfermedad de Behçet, siendo indicativo este medio diagnóstico de fase activa de la enfermedad


Behçet's disease is a chronic, multisystem, autoimmune vasculitis characterized by a triad of key signs. We report the case of a 16-year-old Caucasian girl, who complained of headache, dizziness and paresis of the left side of her body. After physical examination and ancillary tests, she was diagnosed with Behçet's disease with neurological manifestations (neuro-Behçet's disease). She had a good response to treatment. IgG, IgA, IgM and albumin were quantified in serum and cerebrospinal fluid by single radial immunodiffusion. Intrathecal synthesis was found for the 3 classes of immunoglobulins. This is the first case in which the Reibergram was used to evaluate the neuroimmunological response in a patient with Behçet's disease, suggesting the use of this diagnostic means for the active phase of the disease

ABSTRACT

En las meningoencefalitis de etiología viral se encuentran implicados los paramixovirus (virus de la parotiditis, sarampión y rubeola). Las vacunas combinadas trivalentes han sido utilizadas durante años en muchos países. El objetivo del trabajo es determinar la respuesta poliespecífica de anticuerpos de tipo IgG anti parotiditis, rubeola y sarampión en pacientes pediátricos con meningoencefalitis víricas agudas. Se realizó un estudio retrospectivo en el año 2018 en muestras de pacientes pediátricos con meningoencefalitis viral aguda vacunados con la triple viral, donde se utilizó el índice de anticuerpos específicos anti-parotiditis, anti-rubeola y anti-sarampión para identificar el estado de respuesta inmunológica contra dichos virus en la muestra estudiada, procedentes de la serorraquioteca de LABCEL. Las determinaciones se hicieron por ELISA. Todos los pacientes presentaron respuesta poliespecífica intratecal, disminución significativa del índice de anticuerpos IgG anti-parotiditis con respecto a la edad y al tiempo de respuesta. Se evidencia un acortamiento del tiempo de respuesta de los anticuerpos de tipo IgG específicos anti-parotiditis en relación a la edad de vacunación(AU)


Paramixovirus like mumps, rubella and measles are involved in some viral meningoencephalitis. Triple combined vaccines have been employed for several years in many countries. The aim of this work is to determine the IgG anti mumps, rubella and measles polyspecific response in pediatric patients with acute viral meningoencephalitis. A 2018 retrospective study in pediatric patients with acute viral meningoencephalitis previously vaccinated with the triple viral vaccine MMR was performed to identify the immune response status against mumps, rubella and measles in samples from LABCEL serum and cerebrospinal fluid collection. Quantification of IgG specific antibody was performed by ELISA. Intrathecal polyspecific response was present in all patients. A significant decrement of anti IgG mumps specific antibody index was observed according to age and response time. A shortage of the response time of IgG mumps specific antibodies according to the age of vaccination was demonstrated(AU)

ABSTRACT

Introducción: la meningitis/meningoencefalitis criptococócica es una forma infrecuente de infección del sistema nervioso central, producida por Cryptococcus neoformans. Objetivo: mostrar la respuesta neuroinmunológica, a través del reibergrama, en un paciente con meningoencefalitis crónica por Cryptococcus neoformans. Presentación del caso: se cuantificaron los niveles de IgA, IgM, IgG y albúmina en suero y líquido cefalorraquídeo a partir de las cinco punciones lumbares que se le realizó a la paciente y se confeccionó el reibergrama correspondiente. Se comprobó la ocurrencia de síntesis intratecal de, por lo menos, dos clases de inmunoglobulinas mayores, se observó un porciento mayor de síntesis intratecal de IgG. No existió disfunción de la barrera sangre/líquido cefalorraquídeo. Conclusiones: el estudio neuroinmunológico del líquido cefalorraquídeo indica la cronicidad de la entidad. La síntesis intratecal de inmunoglobulinas y el estado de la barrera sangre/líquido cefalorraquídeo constituyen elementos claves en el diagnóstico de la neuroinflamación(AU)

ABSTRACT

Los anticuerpos antinucleares se presentan en el suero de pacientes con enfermedades de origen reumáticas, como el lupus eritematoso sistémico, síndrome de Sjögren, esclerosis sistémica progresiva y polimiositis. En 1948, descubrieron la célula lupus eritematoso y su relación con el lupus eritematoso sistémico, señalando el carácter autoinmune de la enfermedad, al demostrar la existencia de unas sustancias que la llamarían autoanticuerpos. Las pruebas de los anticuerpos antinucleares son muy útiles en el estudio de las enfermedades autoinmunes del tejido conjuntivo. Cada una de ellas dispone de una colección particular de anticuerpos que ayuda, en unos casos, a poder establecer el diagnóstico y, en otros, además, a señalar el pronóstico de la enfermedad


Antinuclear antibodies present in the serum of patients with rheumatic diseases origin, such as Systemic Lupus Erythematosus, Sjögren's syndrome, Progressive Systemic Sclerosis and Polymyositis. In 1948, they discovered the lupus Erythematosus cell and its relationship with Systemic Lupus Erythematosus, pointing to the autoimmune nature of the disease, by demonstrating the existence of substances that autoantibodies call. Testing antinuclear antibodies are very useful in the study of autoimmune connective tissue diseases. Each has a private collection of antibodies that help, in some cases, be able to establish the diagnosis, in others point the prognosis of the disease. There proteins is very important, and it constitutes a valuable tool like marker inflammatory in rheumatologic illnesses of immunological origin

ABSTRACT

Introducción: Angiostrogylus cantonensis es un helminto que vive en las arterias pulmonares de dos especies de ratas: Rattus rattus y Rattus norvergicus. El hombre es un hospedero accidental que se infecta al ingerir las larvas de tercer estadio a través de vegetales o frutas mal lavados y por la ingestión de diferentes especies de moluscos, que constituyen los hospederos intermediarios. Objetivo: caracterizar las condiciones de humedad, temperatura y lluvia caída en las zonas donde se reportaron los pacientes y su vinculación con la aparición de los casos de meningoencefalitis eosinofílica por Angiostrongylus cantonensis. Material y Métodos: se estudiaron 34 pacientes diagnosticados con esta enfermedad que fueron ingresados en el Hospital Pediátrico San Miguel del Padrón, en La Habana, Cuba, en el período de enero de 1991 hasta enero del 2014. Para la obtención de los datos correspondientes a las variables meteorológicas se acudió con la fecha de ingreso de los enfermos a los registros diarios y mensuales del Instituto de Meteorología. Se calcularon los coeficientes de correlación para cada variable meteorológica y el número de casos y se ajustaron las rectas de regresión correspondientes. Resultados: los enfermos se concentraron en períodos en que la humedad promedio anual osciló entre 75 y 76 por ciento, mientras que la humedad ambiental varío entre 65 y 80 por ciento. La probabilidad de encontrar casos enfermos es mayor entre los años con lluvia anual promedio entre 68 y más de 120 mm. Para la temperatura, la correlación fue negativa, a medida que se registra un aumento de temperatura hay una disminución del número de enfermos. Conclusiones: el mayor número de casos de enfermos coincide con las condiciones de humedad ambiental y temperatura optimas para el desarrollo de las larvas de tercer estadio en los caracoles(AU)


Introduction: Angiostrongylus cantonensis is a helmint that lives in the pulmonary arteries of two rats species: Rattus rattus and Rattus norvergicus. Human is an accidental host that is infected by ingestion of third larvae stage in bad washed vegetables, fruit and different species of mollusks which constitute the intermitted hosts. Objective: to characterize the humidity, temperature and rain fall in zones where were reported the patients and its relation with the eosinophilic meningoencephalitis cases by Angiostrongylus cantonensis. Material and Methods: 34 patients were diagnosed with this illness. They were admitted at Hospital Pediatric San Miguel del Padrón, Havana, Cuba from January 1991until January 2014. In order to obtain of meteorological variables data we remit to the admission patient date and dairy and monthly register of the Meteorology Institute. Were calculated the correlation coefficient for each meteorological variable and the number of cases related to the different variables and the regression lines were performed. Results: the more quaintly of patients were grouped in periods where annual average fluctuated between 75 y 76 % and environment humidity oscillated between 65 y 80 percent.The probability to find illness cases is major in the years with average annual rain between 68 and more of 120mm. An inverse correlation was observed for temperature. Conclusions: the larger number of reported cases coincides with the best conditions of environmental humidity and temperature for the development of the third stage larvae in mollusks(AU)

ABSTRACT

Angiostrongylus cantonensis is a zoonotic pathogen that occasionally causes human angiostrongyliasis; its main clinical manifestation is eosinophilic meningitis. This report defines the concept of intrathecal activation of complement as evidence of intrathecal synthesis of major immunoglobulins during this disease. Details are presented of the activation of complement system components in cerebrospinal fluid, and their application to our understanding of this tropical disease, which is emerging in the Western hemisphere. Intrathecal synthesis of at least one of the major immunoglobulins and a wide spectrum of patterns may be observed. Although intrathecal synthesis of C3c is always present, C4 intrathecal synthesis does not occur in every patient. The diversity of intrathecal synthesis and activation of the different complement pathways enables their division into three variant groups (A, B, and C). Variant group A includes the classical and/or lectin pathway and involves two or more major immunoglobulins with C3 and C4 intrathecal synthesis. Variant group B involves C4 in cerebrospinal fluid that comes from blood in the intrathecal activation of the classical pathway. Variant group C includes the alternative pathway.
