ABSTRACT

BACKGROUND: The incidence of eosinophilic esophagitis (EoE) is increasing in some regions of the world. Retrospective studies have found an inverse association with Helicobacter pylori infection (H. pylori). A recent prospective study has questioned this relationship. We aimed to evaluate this relationship in Mexican patients. PATIENTS AND METHODS: We evaluated adult patients without prior eradication of H. pylori. Cases were defined by the presence of esophageal symptoms and >15 eosinophils/high power field (HPF) in the esophageal biopsy. Controls were defined by the presence of <15 eosinophils/HPF in esophageal biopsy. H. pylori infection was defined by histology. Patients were matched by age and gender assigning four controls per case. RESULTS: We included 190 patients: 38 cases and 152 controls. Cases had higher frequency of atopy, dysphagia, food impaction, peripheral eosinophilia, and endoscopic EoE abnormalities. The overall prevalence of H. pylori was 63.6%. Cases had significantly lower prevalence of H. pylori than controls (36.8% vs. 70.4%, OR 0.21 95% CI 0.08-0.69, p = 0.001). Atopic patients had lower prevalence of H. pylori than non-atopic: 13.1% vs. 50.5% (OR 0.20, 95% CI 0.06-0.69, p < 0.001), particularly allergic rhinitis and food allergy. CONCLUSIONS: We observed an inverse relationship between H. pylori and EoE as well as atopy. Studies in experimental models of EoE that clarify the role of H. pylori in this interaction are required, as well as robust studies that include other factors (socioeconomic, cultural, microbiota, etc.) in order to clarify this relationship.

ABSTRACT

Canine atopic dermatitis (cAD) is a multifactorial allergic disease associated with immune dysfunction and abnormal skin barrier. Several immunological mediators play a role in its pathogenesis. Such molecules are produced by the activation of T helper lymphocytes (Th) through polarization to Th1 and/or Th2, which contributes to different lesion patterns. Acute lesions are mediated by an activation of the Th2 cytokine axis, which clinically induces erythema and pruritus. Conversely, in chronic injuries a mixed immune response of Th1/Th2 cytokines occurs, leading to hyperpigmented and lichenified skin. The clinical understanding of these patterns and the mode of action of immunomodulators are crucial for the best clinical management of the atopic patient. In this context, this review discussed the role of the immune response and the immunomodulatory drugs in dogs with atopic dermatitis and suggested a therapeutic protocol based on clinical phenotype. Based on the evidences showed in this review, it is considered appropriate to use immunomodulatory drugs that target cytokine spectrum related with the clinical phenotype of cAD.


A dermatite atópica canina (DAC) é uma doença alérgica multifatorial associada à disfunção imune e barreira cutânea anormal. Vários mediadores imunológicos desempenham um papel na sua patogênese. Tais moléculas são produzidas pela ativação de linfócitos T auxiliares (Th) por meio da polarização para Th1 e/ou Th2, o que contribui para diferentes padrões de lesão. Lesões agudas são mediadas pela ativação do eixo de citocinas Th2, que clinicamente induz eritema e prurido. Por outro lado, nas lesões crônicas ocorre uma resposta imune mista de citocinas Th1/Th2, levando à pele hiperpigmentada e liquenificada. O entendimento clínico desses padrões e o modo de ação dos imunomoduladores são cruciais para o melhor manejo clínico do paciente atópico. Esta revisão visa discutir o papel da resposta imune e das drogas imunomoduladoras em cães com dermatite atópica e sugerir um protocolo terapêutico baseado no fenótipo clínico. Baseado nas evidências apresentadas nessa revisão, é considerado apropriado utilizar drogas imunomoduladoras que abrangem o espectro de citocinas relacionadas ao fenótipo clínico da DAC.

ABSTRACT

BACKGROUND: Recent information on the prevalence of allergic sensitization (AS) in children from low-income urban areas is limited. METHODS: We conducted a cross-sectional, randomized, population-based study to determine the prevalence of AS, and its relationship with asthma and rhinitis in low-income schoolchildren in Santiago, Chile. The parents answered a standardized questionnaire on respiratory symptoms, and a skin prick test (SPT) for common aeroallergens was performed on all children. RESULTS: In the 545 schoolchildren studied (mean age 8.3 ± 0.9 years), the prevalence of positive SPT was 25.5%. The current prevalence of asthma, rhinitis, and rhinoconjunctivitis was 20%, 43.4%, and 27.8%, respectively. SPT was positive in 30.6%, 32.8%, and 38.0% of children with current asthma, rhinitis, and rhinoconjunctivitis, respectively. Positive SPT was significantly associated with rhinitis and rhinoconjunctivitis (p < 0.001) but not with asthma. Breastfeeding for at least 4 months was significantly protective against AS (odds ratio [OR] 0.48, 95% confidence interval [CI] 0.26-0.78; p = 0.008); no other factor studied was associated with AS. CONCLUSIONS: The prevalence of AS was low; less than 40% of children with current asthma, rhinitis, or rhinoconjunctivitis symptoms evidenced AS. The prevalence of non-atopic asthma and rhinitis is consistent with previous findings in children from low-income urban areas. Other environmental factors, such as the high burden of respiratory infections and environmental pollution, might be more critical than atopy for developing asthma and rhinitis in schoolchildren from deprived urban areas.


INTRODUCCIÓN: La información reciente sobre la prevalencia de sensibilización alérgica (SA) en niños de áreas urbanas de bajos recursos es limitada. MÉTODOS: Se realizó un estudio transversal, aleatorio, a nivel poblacional, para determinar la prevalencia de SA y su relación con asma y rinitis en escolares de bajos recursos en Santiago de Chile. Los padres respondieron un cuestionario estandarizado de síntomas respiratorios y se realizaron pruebas cutáneas (PC) para alérgenos comunes en los niños. RESULTADOS: En los 545 escolares estudiados (media de edad 8.3 ± 0.9 años) la prevalencia de PC positivas fue del 25.5%. La prevalencia actual de asma, rinitis y rinoconjuntivitis fue del 20%, 43.4% y 27.8%, respectivamente. Las PC fueron positivas en el 30.6%, 32.8% y 38.0% de los niños con síntomas actuales de asma, rinitis y rinoconjuntivitis, respectivamente. La rinitis y la rinoconjuntivitis se asociaron significativamente con PC positiva (p < 0.001), pero no el asma. La lactancia materna por al menos cuatro meses protegió significativamente contra SA (razón de momios [RM] 0.48, intervalo de confianza [IC] 95% 0.26-0.78; p = 0.008); ningún otro factor estudiado se asoció con SA. CONCLUSIONES: La prevalencia de SA fue baja; menos del 40% de los niños con síntomas actuales de asma, rinitis o rinoconjuntivitis evidenció SA. La alta prevalencia de asma y rinitis no atópicas concuerda con hallazgos previos en niños de áreas urbanas de bajos ingresos. Otros factores ambientales como la alta carga de infecciones respiratorias y contaminación ambiental podrían ser más importantes que la atopia para el desarrollo de asma y rinitis en escolares de áreas urbanas desfavorecidas.

ABSTRACT

Desde la perspectiva clínica, la atopia o atopía es un fenómeno dual, de una parte tiene la connotación de una repuesta inmunitaria genéticamente determinada, y, de otro lado, una expresión clínica enmarcada en la denominada marcha atópica; con la identificación de diversos signos, síntomas o entidades clínicas, que conforman múltiples fenotipos que pueden expresarse en el curso de vida del paciente atópico se identifican más avances sustantivos en la descripción de haplotipos condicionantes de la respuesta inmunitaria y sus variantes, así como de la diversa presentación de enfermedades atópicas y de la respuesta a los tratamientos utilizados. Objetivo: realizar una actualización de la atopia y de los avances inmunopatológicos / inmunogenéticos, en interrelación a factores propios (físicos y psíquicos) y de interacción con el microbioma y el ambiente externo. Material y Métodos: se realizó una búsqueda en diferentes fuentes de acceso electrónico y manual, utilizando como descriptores clave: atopia, hipersensibilidad, respuesta inmune, microbioma, epigenética, autoinmunidad. Conclusión: Se reconoce a la alergia como la expresión clínica de los mecanismos de respuesta inmunitaria, frente a posibles invasores (alérgenos) que proceden del ambiente externo. Un error inmunológico de respuesta exagerada, generalmente mediada por células Th2 e IgE, por intolerancia antigénica es la explicación de la atopia...(AU)

ABSTRACT

Abstract The aim was to determine the prevalence and types of the allergies present among dental professionals in Costa Rica. We performed a cross-sectional study on 664 dentists who completed a self-reported questionnaire. A descriptive cross-sectional study with inferential analysis was carried out. Dentists reported allergies prior to studying dentistry in 39% of cases, 36% reported chronic illnesses, and 61% of the dentists reported first-degree relatives with some type of allergic reaction. Different allergies had a similar prevalence among the dental professionals (ranging between 19%-26%), all allergic manifestations occurred within the first 120 minutes after exposure. The average time of exposure to dentistry-related environments was 16 years (95% CI) among all the dentists surveyed. There is a positive correlation between the presence of a chronic illness and the predisposition to develop allergic reactions among dentists. In addition, there is a directly proportional relationship between age, time of exposure to dental environments, and the risk of developing allergic conditions to dental materials. The main adverse reactions reported due to exposure to dental materials, medicines and/or food were gastrointestinal, skin, and respiratory problems.


Resumen El objetivo del estudio fue determinar la prevalencia y tipo de alergias presentes entre los odontólogos en Costa Rica. Se realizó un estudio transversal descriptivo en 664 dentistas que completaron un cuestionario, utilizando análisis inferencial para el procesamiento de los resultados. Los odontólogos reportaron alergias previo a estudiar odontología en un 39% de los casos, el 36% informó enfermedades crónicas y el 61% de los dentistas mencionó tener familiares en primer grado que habían presentado algún tipo de reacción alérgica. Diferentes tipos de alergias tuvieron una prevalencia similar entre los odontólogos (oscilando entre el 19% y el 26%), todas las manifestaciones alérgicas ocurrieron dentro de los primeros 120 minutos después de la exposición al alergeno. El tiempo medio de exposición a entornos relacionados con la odontología fue de 16 años (IC del 95%) entre todos los dentistas encuestados. Existe una correlación positiva entre la presencia de una enfermedad crónica y la predisposición a desarrollar reacciones alérgicas entre los dentistas. Además, existe una relación directamente proporcional entre edad, tiempo de exposición a entornos dentales, y el riesgo de desarrollar reacciones alérgicas a los materiales dentales. Las principales reacciones adversas notificadas posterior a la exposición a materiales dentales, medicamentos y/o alimentos fueron problemas gastrointestinales, cutáneos y respiratorios.

ABSTRACT

Neste artigo tomamos os conceitos de ideologia e utopia a partir de Paul Ricoeur, de distopia a partir de François Ost e apresentamos o conceito de entopia, a fim de resgatar uma dimensão de factibilidade, ausente nos dois primeiros e distorcida no terceiro, presente em uma nova forma de compreender a relação natureza-cultura. Para tanto, dentro de um contexto de abertura cognitiva para o mundo empírico, usamos como base um caso paradigmático cuja interpretação contemplou tais conceitos e alguns de seus usos. Trata-se da trajetória da família de Leonel Siqueira da Silva que, ao longo de vinte e cinco anos, reivindicou o direito de permanecer no Morro das Andorinhas, região oceânica da cidade de Niterói/RJ. O acompanhamento das controvérsias conduziu a construção do conceito de entopia, que convida a nos reencantarmos com o mundo, tornar lugares habitáveis permanentemente, acoplar, harmonizar as representações locais, as formas culturais vividas, com novos regramentos do tempo, do espaço e do direito.(AU)


In this article we take the concepts of ideology and utopia from Paul Ricoeur, of dystopia from François Ost and offer the concept of understanding the relationship between nature and culture. We will describe, from a cognitive openness to the empirical world, a paradigmatic case whose interpretation contemplated such concepts and some of their uses. That's the saga of Leonel Siqueira da Silva's family who, for twenty-five years, claims the right to remain in the Morro das Andorinhas, oceanic region of the city of Niterói / RJ. The follow up of the controversies led the construction of the concept of entopia, which invites us to rekindle with the world, to make places permanently habitable, to couple, to harmonize local representations, to live cultural forms with new rules of time, space and law "atopia" in order to recover the dimension of feasibility, absent in the two first and distorted in the third, in a new way of.(AU)

ABSTRACT

Introdução: Esofagite eosinofílica (EoE) é uma doença inflamatória crônica do esôfago, mediada imunologicamente e caracterizada por sintomas relacionados com disfunção esofágica e infiltração da mucosa esofágica por eosinófilos (Eo). Os objetivos foram caracterizar os doentes com diagnóstico de EoE e analisar as diferenças entre doentes com diagnóstico em idade pediátrica (Cr, < 18 anos) e adulta (Ad, ≥ 18 anos). Métodos: Estudo observacional retrospetivo dos doentes seguidos no serviço de Imunoalergologia, no período de Fev/2009 a Jul/2017, com diagnóstico de EoE. Foram divididos em dois grupos, Cr e Ad, caracterizados de acordo com dados demográficos, história de atopia, sintomas, sensibilizações alimentares, IgE Total, eosinofilia, achados na endoscopia digestiva alta e biópsias. Avaliou-se a correlação entre sensibilização alimentar, clínica grave (ClinG), ou seja, idas ao serviço de urgência ou internamento por complicações de EoE ou histologia grave (HistG), biópsia com Eo > 50 e/ou microabcessos. Resultados: 74 pacientes (81% sexo masculino, média de idades 27±17 anos), 36 Cr e 38 Ad. Os sintomas mais frequentemente reportados foram, no grupo Cr disfagia (73%) e refluxo gastroesofágico (46%), enquanto no grupo Ad impactação (85%) e disfagia (56%). Foram referidos antecedentes de atopia em 96% das Cr, e 67% dos Ad. Em 77% das Cr e 69% dos Ad havia sensibilização alimentar. Os achados endoscópicos mais frequentes no grupo Cr foram estriação (65%) e placas brancas (50%), enquanto que no grupo Ad foram placas brancas (42%) e anéis esofágicos (35%). HistG (46%) associou-se a ClinG (35%), p = 0,001, nas Cr, mas o mesmo não foi objetivado no grupo Ad [ClinG (22%) e HistG (17%), p = 0,5]. Conclusão: Os nossos resultados estão de acordo com o descrito na literatura, observando-se um predomínio do sexo masculino e uma maior frequência de história de atopia e sensibilização alimentar no grupo Cr. As situações graves de impactação e estenose esofágica foram mais frequentes nos Ad, e objetivou-se uma associação de histologia grave com clínica grave, apenas nas Cr.


Background: Eosinophilic esophagitis (EoE) is an immunologically mediated chronic inflammatory disease of the esophagus characterized by symptoms related to esophageal dysfunction and eosinophilic infiltration in the esophageal mucosa. This study aimed to characterize patients with a diagnosis of EoE and analyze differences between patients with EoE diagnosed at pediatric age (Ch, <18 years) and at adult age (Ad, ≥18 years). Methods: This was a retrospective study of patients with a diagnosis of EoE who were followed in the immunoallergology department from February 2009 to July 2017. Patients were divided into Ch and Ad groups and characterized according to demographic data, history of atopy, symptoms, food sensitization, total IgE, eosinophils (Eo), upper digestive endoscopy (UDE) findings, and biopsy findings. Correlations were assessed between food sensitization, clinical severity (SClin; determined by number of ER visits or hospital admissions for EoE complications), and severe histology (SHist; defined as biopsy with Eo >50 and/or microabscesses). Results: 74 patients (81% male, mean age 27±17 years), 36 Ch and 38 Ad. The most commonly reported symptoms were dysphagia (73%) and gastroesophageal reflux (46%) in the Ch group, and impaction (85%) and dysphagia (56%) in the Ad group. History of atopy was reported in 96% of Ch vs 67% of Ad. Food sensitization was found in 77% of Ch vs 69% of Ad. The most common UDE findings were striation (65%) and white plaques (50%) in the Ch group, and white plaques (42%) and esophageal rings (35%) in the Ad group. SHist (46%) was associated with SClin (35%) in Ch (p=0.001), but not in Ad (SClin [22%] and SHist [17%], p=0.5). Conclusion: Our results are consistent with those reported in the literature, with a male predominance and a higher prevalence of atopy and food sensitization in Ch. Severe impaction and esophageal stenosis were more frequent in Ad, but an association between SHist and SClin was found only in Ch.

ABSTRACT

A dermatite atópica canina (DAC) é uma dermatopatia inflamatória, crônica e pruriginosa que afeta indivíduos geneticamente predispostos, sendo comumente associada à produção de anticorpos do tipo IgE. O presente relato objetivou descrever um caso de DAC, evidenciando seus sinais clínicos, diagnóstico e tratamento. Foram realizados teste com lâmpada de Wood, raspado profundo de pele, imprint cutâneo, cultura fúngica e bacteriana, citologia de ouvido, exame sorológico para leishmaniose visceral canina (LVC) e teste de sensibilidade a alérgenos. O paciente apresentava uma série de lesões dermatológicos disseminadas acompanhadas de prurido intenso, onde pode-se observar presenças de infecções secundárias por bactérias e leveduras fúngicas. Dessa forma, optou-se por tratamento tópico com shampoo a base de clorexidina 2% associado a miconazol 2,5% e uso de creme hidratante. Para otite bilateral, prescreveu-se solução otológica de ciclopirox olamina 1% e ácido glicirrízico 0,5%. Após resposta negativa ao tratamento inicial, introduziu-se o uso oral de prednisolona associado à hidroxizina e logo depois a ciclosporina, ocorrendo um controle do quadro. Embora várias alternativas terapêuticas estejam disponíveis, a cura ainda não é possível, sendo o controle do quadro lesional a melhor abordagem de tratamento.(AU)


The canine atopic dermatitis (CAD) is an inflammatory skin disease, chronic itchy that affects genetically predisposed individuals, being commonly associated with production of IgE antibodies. The aim of this study was to describe a case of CAD, evidencing its clinical signs, diagnosis and treatment. A Wood lamp, skin deep scraping, skin imprint, fungal and bacterial culture, ear cytology, serological examination for canine visceral leishmaniasis (LVC) and allergen sensitivity test were performed. The animal presented a series of disseminated dermatological lesions accompanied by intense pruritus, where it is possible to observe presences of secondary infections by bacteria and yeasts fungi. Thus, it was decided to topical treatment with shampoo chlorhexidine base 2% associated with miconazole 2.5% and use moisturizer. For bilateral otitis, otologic solution of cyclopirox olamine 1% and glycyrrhizic acid 0.5% was prescribed. After negative response to the initial treatment, the oral use of prednisolone associated with hydroxyzine and soon after cyclosporine was introduced, and clinical control was performed. Although several therapeutic alternatives are available, cure is still not possible, and lesion control is the best treatment approach.(AU)

ABSTRACT

A dermatite atópica canina (DAC) é uma dermatopatia inflamatória, crônica e pruriginosa que afeta indivíduos geneticamente predispostos, sendo comumente associada à produção de anticorpos do tipo IgE. O presente relato objetivou descrever um caso de DAC, evidenciando seus sinais clínicos, diagnóstico e tratamento. Foram realizados teste com lâmpada de Wood, raspado profundo de pele, imprint cutâneo, cultura fúngica e bacteriana, citologia de ouvido, exame sorológico para leishmaniose visceral canina (LVC) e teste de sensibilidade a alérgenos. O paciente apresentava uma série de lesões dermatológicos disseminadas acompanhadas de prurido intenso, onde pode-se observar presenças de infecções secundárias por bactérias e leveduras fúngicas. Dessa forma, optou-se por tratamento tópico com shampoo a base de clorexidina 2% associado a miconazol 2,5% e uso de creme hidratante. Para otite bilateral, prescreveu-se solução otológica de ciclopirox olamina 1% e ácido glicirrízico 0,5%. Após resposta negativa ao tratamento inicial, introduziu-se o uso oral de prednisolona associado à hidroxizina e logo depois a ciclosporina, ocorrendo um controle do quadro. Embora várias alternativas terapêuticas estejam disponíveis, a cura ainda não é possível, sendo o controle do quadro lesional a melhor abordagem de tratamento.

ABSTRACT

A dermatite atópica canina ganha destaque mundial pela alta incidência e recentes descobertas sobre sua complexa fisiopatogenia. Este estudo avaliou os efeitos da terapia com oclacitinib a sobre o escore de prurido de 20 cães com dermatite atópica, diagnosticados com estritos critérios de exclusão, em três momentos (dias 0, 14 e 28) segundo escalas quantitativa e qualitativa, na óptica dos proprietários. A terapia via oral reduziu em mais de 50% a intensidade do prurido em 85% dos cães, em doses de 0,4 a 0,6 mg/kg a cada 12 horas. O uso da mesma dose a cada 24 horas mostrou que 80% dos animais obtiveram redução do prurido, em média de 44%. Não houve reações adversas ao uso do ativo nos 28 dias de avaliação. O oclacitinib ' mostrou ser eficiente no tratamento de cães com dermatite atópica, com altos índices de redução de prurido em ambas as posologias, sobretudo no uso a cada 12 horas.(AU)

Canine atopic dermatitis gains worldwide attention due to its high incidence, and to recent discoveries about its complex pathophysiology. This study evaluated the effects of oclacitinib on pruritus scores of 20 dogs with atopic dermatitis. Levels of pruritus described by owners were diagnosed based on strict exclusion criteria, at 3 moments (days 0, 14 and 28), by quantitative and qualitative scales. In 85% of the dogs, oral admnistration of 0.4 - 0.6 mg/kg twice daily resulted in more than 50% reduction in pruritus leveI. The same dose once daily reduced pruritus in 80% of the animals, being 44% the average reduction. None of them presented adverse reactions during the 28 days of evaluation. Oclacitinib has shown efficiency in the treatment of dogs with atopic dermatitis, with high rates of pruritus reduction in both dosages, especially when used every 12 hours.(AU)

ABSTRACT

RESUMEN La anafilaxia se define como una reacción de hipersensibilidad, sistémica, de instauración rápida y potencialmente fatal, con manifestaciones clínicas y severidad variable, que resulta de la liberación súbita de mediadores de mastocitos y basófilos. El diagnóstico de esta entidad es fundamentalmente clínico, basándose en los patrones de manifestación y la exposición a un posible detonante. Actualmente varios estudios indican deficiencias en la identificación y manejo de esta enfermedad, lo que genera un riesgo elevado de mortalidad. En esta revisión presentamos puntos prácticos del manejo e identificamos las principales consideraciones a tener en cuenta en el primer nivel de atención.


SUMMARY Anaphylaxis is defined as a systemic, rapid onset, and potentially fatal hypersensitivity reaction, with variable clinical manifestations and severity resulting from the sudden reléase of mast cell and basophil mediators. The diagnosis of this entity is fundamentally clinical, based on the patterns of manifestation and the exposure to a possible trigger. Currently several studies indicate deficiencies in the identification and management of this disease, which generates an increase in mortality. In this review we present practical points of management and identify the main considerations to be taken into account in the first level care.

ABSTRACT

Se realizó un estudio epidemiológico analítico, de casos y controles en fase exploratoria, con vistas a determinar si la frecuencia de infecciones respiratorias en niños y adolescentes con asma de la provincia de Pinar del Río superaba la observada en aquellos que no presentaban esa enfermedad, desde julio del 2014 hasta junio del 2015. Para ello se conformaron 2 grupos de 585 integrantes cada uno, o sea un control por cada caso. Luego de procesada la información, se obtuvo un predominio del sexo masculino, en tanto, el catarro común fue la infección que afectó con mayor frecuencia fundamentalmente a los pacientes de 5-9 años de edad. Asimismo, se destacó un incremento del riesgo de padecer -- por orden de frecuencia -- afecciones, tales como catarro común, amigdalitis aguda y neumonía, bronconeumonía, así como neumonía intersticial(AU)


An analytic epidemiologic, of cases and controls study in exploratory phase, aimed at determining if the frequency of breathing infections in children and adolescents with asthma from Pinar del Río exceeded the one observed in those that didn't present that disease, was carried out from July, 2014 to June, 2015. Two groups of 585 members each one were conformed for that purpose, that is to say a control for each case. After having processed the information, there was a prevalence of the male sex, while, the common cold was the infection that affected with higher frequency fundamentally those patients aged 5-9. Also, it was emphasized an increment of the risk from suffering -- in order of frequency -- disorders, such as common cold, acute tonsillitis and pneumonia, bronchopneumonia, as well as interstitial pneumonia(AU)

ABSTRACT

Respiratory viral infections have been implicated in the origin and exacerbation of asthma symptoms in a variety of ways. A growing body of evidence indicates that viral infections are closely linked to infantile wheezing and suggest that severe bronchiolitis in early infancy may predispose to chronic childhood asthma. Alternatively, it could represent a marker of susceptible individuals. In contrast, mild repetitive infections in early years may provide a protective role against the development of asthma or atopy by switching the immune system towards Th1 responses. However, evidence on this hypothesis is not consistent as far as viruses are concerned. On the other hand, in the presence of asthma, the role of viral infections on exacerbations is well established. Several factors, such as the presence of atopy, timing of the exposure and severity of the infections, interactively contribute to the asthma-infection relationship. In the present report, recent data on the involvement of viral infections in the development and progression of asthma are reviewed


Las infecciones virales respiratorias han sido involucradas en el origen y en las exacerbaciones de los síntomas del asma en una variedad de formas. Cada vez hay más indicios de que las infecciones virales están estrechamente relacionadas con sibilancias en la niñez y sugieren que la bronquiolitis grave en la primera infancia puede predisponer a asma crónica infantil; por otra parte, podría representar un marcador de individuos susceptibles. Por el contrario, las infecciones leves repetidas en los primeros años brindarían un efecto protector contra la aparición de asma o atopia mediante la desviación del sistema inmunitario hacia respuestas Th1. Sin embargo, la información relacionada con esta hipótesis no es firme en lo que a virus se refiere. Por otra parte, en presencia de asma, el papel de las infecciones virales sobre las exacerbaciones está bien establecido. Varios factores, como la presencia de atopia, el momento en el que se produce la exposición y la gravedad de las infecciones, interactúan en la relación entre asma e infección. En este artículo se revisan datos acerca de la participación de las infecciones virales en la aparición y progresión del asma

ABSTRACT

El dermografismo, conocido como "escritura sobre la piel", fenómeno que ocurre en forma espontánea o a la provocación física de la misma, es un síntoma, signo o síndrome semiológico, característico de procesos clínicos alérgicos y no alérgicos. Se expresa comúnmente como dermografismo rojo (urticaria dermatográfica, con o sin angioedema acompañante), con eritema y/o roncha muy frecuente en procesos alérgicos, pero también en las urticarias físicas, autoinmunes o tóxicas por aditivos alimentarios, infecciones, medicamentos y otros agentes. El dermografismo blanco, que se evidencia como un área que palidece alrededor de la línea de estimulación física, muy característico de la atopia; y, el que en esta comunicación hemos denominado dermografismo "mixto o bifásico", por su carácter bimodal, en el que se alternan las expresiones de los dermografismos rojo y blanco, en forma casi simultánea o en sucesión de blanco temprano en el primer minuto a rojo tardío a los cinco minutos o más, o al contrario, rojo inmediato y blanco posterior, típico de atopia. El paciente con hiperreactividad atópica en piel es el que exhibe el dermografismo mixto o bifásico, pues muestra el dermografismo blanco como estigma de atopia y el dermografismo rojo de la urticaria sintomática aguda o crónica. Esta última forma de dermografismo no se encuentra en las descripciones clásicas y es el objetivo de esta comunicación, que se acompaña de una amplia discusión sobre la ocurrencia de dermografismo en la práctica clínica. Material y Métodos: Se realizó una extensa revisión bibliográfica, consultando bases de datos como Medline, PubMed, DocChek, Wiley, Amedeo, Cochrane, Scielo, Hinari y Lilacs; se presentan viñetas clínicas de casos de pacientes atópicos. Conclusión: En esta revisión se ha presentado la ocurrencia clínica del dermografismo como un fenómeno frecuente de diferentes orígenes, pero que, muchas veces, es acompañante casi invariable de expresiones atópicas, en donde el dermografismo es un signo de ayuda para la tipificación del paciente alérgico...(AU)

ABSTRACT

Introducción: Las enfermedades atópicas, asma, rinitis alérgica y dermatitis atópica son enfermedades crónicas comunes, presentando una alta prevalencia a nivel mundial y la cual se desconoce su prevalencia en Guatemala. Objetivos: El presente estudio es el de evaluar la incidencia de enfermedad atópica en una población pediátrica que asiste a un hospital estatal de la Ciudad de Guatemala, así como, conocer la prevalencia de cada una de estas condiciones por separado. Metodología: Se tomó una muestra de 386 sujetos ambulatorios escogiendo dos grupos entre 5 a 6 años de edad el primero y de 11 a 12 años en el segundo. Se usó un cuestionario adaptado de la versión validada en español del estudio ISAAC. (11) Resultados: Se estimó una prevalencia de síntomas de asma, rinoconjuntivales y cutáneos en niños de 5 a 6 años de 13%, 14% y 7% respectivamente. En el grupo de 11 a 12 años fue de 16%, rinoconjuntivales 16%, y cutáneos 14 %. Discusión: La prevalencia varía comparada con la de otros países de Latino América probablemente por diferencias geográficas, poblacionales, inmunológicas y genéticas. El 59% de los pacientes no contaban con diagnóstico ni tratamiento, lo cual indicó que no se cuenta con herramientas para la detección temprana de enfermedades atópicas.


diseases with a high worldwide prevalence not known in Guatemala. Objectives: The main purpose of the study is to know de prevalence of atopic diseases in children followed as outpatients in a public hospital in Guatemala. Methodology: A population of 386 children was studied and divided in two groups, one ages 5 to 6 years and the second one ages 11 to 12 years. An adapted questionnaire from the study of ISAAC (11) was validated and used. Results: The estimated prevalence of asthma, rhinoconjuntivitis and cutaneous symptoms in children aged 5 to 6 year old was 13%, 14% and 7%, respectively. In the group ranged 11 to 12 prevalence of symptom of asthma was 16%, rhinoconjuntival 16% and cutaneous 14%. Discussion: A high prevalence of symptoms of the 3 diseases, in both age groups was found, however this prevalence varies compared with other Latin American countries; this is probably due to geographical, demographic, immunological and genetic differences. Fifty-nine (59%) of subjects had no diagnosis or treatment indicating the absence of screening tools for the early detection of atopic diseases.
