ABSTRACT

Introduction: The home environment is one of the most favorable spaces for the development of mites because of its low light, humidity, and temperature. Thus, it contributes to the growing cases of allergies among atopic individuals. Objective: To investigate the faunal profile of house dust mites in the city of Rio de Janeiro and the allergenic potential in this region. Methods: Thirty dust samples were collected from homes in the city of Rio de Janeiro, and the species found were classified according to their morphology, family, and genus by classification key. For the collection region, the total protein level was assessed by the Lowry method and electrophoresis under denaturing conditions (SDSPAGE). Results: There was a predominance of Pyroglyphidae mites, accounting for 84.9% of samples; Tyrophagus putrescentiae accounted for 8%, Blomia tropicalis for 6%, Cheyletus malaccensis for 1%, and Acarus siro for 0.1%. The allergen protein content of the samples was the following: group 1 ­ 25 kDa (Der 1, Der p 1, and Blo t 1), group 2 ­ 15 kDa (Der f 2, Der 2, Tyr p 2, and Blo t 2), and group 3 ­ 29-30 kDa (Der f 3 and Blo t 3), which indicates that people in this region are susceptible to sensitization to these mites. Conclusion: Knowledge of the mite fauna in the region under study allows the guidance of health care professionals to perform skin tests for specific mites and conduct treatment according to the pool of mite extracts containing antigens, making immunotherapy more effective.


Introdução: O ambiente domiciliar é um dos espaços favoráveis para o desenvolvimento de ácaros, tendo em vista a baixa luminosidade, umidade e temperatura, o que contribui para os crescentes casos de alergias em indivíduos atópicos. Objetivo: Investigar o perfil faunístico dos ácaros na cidade do Rio de Janeiro e o potencial alergêncio para essa região. Métodos: Foram coletadas 30 amostras de poeira em residências na cidade do Rio de Janeiro, e as espécies encontradas foram classificadas quanto à morfologia, família e o gênero por chave de classificação. Para as regiões das coletas, a carga total de proteínas contendo os alérgenos foi determinada pelo método de Lowry e eletroforese em condições desnaturantes (SDS-PAGE). Resultados: Os resultados mostram a predominância de 84,9% de ácaros da família Pyroglyphidae; para os demais ácaros o percentual corresponde a 8% Tyrophagus putrescentiae, 6% Blomia tropicalis, 1% Cheyletus malaccensis, e 0,1% de Acarus siro. O conteúdo proteico alergêncio constituinte das amostras foram, grupo 1: 25 kDa (Der 1, Der p 1 e Blo t 1); grupo 2: 15 kDa (Der f 2, Der 2, Tyr p 2 e Blo t 2); e para o grupo 3: 29-30 kDa (Der f 3 e Blo t 3), o que indica uma região passível à sensibilização de indivíduos por estes ácaros. Conclusão: O conhecimento da acarofauna nas regiões em estudo permite orientar a comunidade médica quanto à realização de testes cutâneos, além da terapêutica a partir do pool de extratos de ácaros contendo os antígenos, a fim de tornar a imunoterapia mais eficaz.

ABSTRACT

Objetivo Determinar la relación del ejercicio con los niveles séricos de la apoA-I y las subpoblaciones de HDL2 y HDL3, en personas hipertensas de la Ciudad de Armenia - Quindío. Métodos La intervención fueron dos meses de ejercicio. La presión arterial se tomó con las recomendaciones del Ministerio de Salud de Colombia. Las subpoblaciones de HDL se midieron con el método del precipitado ionico y la apoA-I se midió con la técnica de nefelometría de bindig site. Resultados Los datos se analizaron con estadística descriptiva e inferencial. Se captaron 160 pacientes de los cuales 125 permanecieron hasta el final del proyecto, es decir, hubo un 78,12 % de permanencia; el 28 % hicieron ejercicio. El análisis mostró una reducción altamente significativa de la tensión arterial sistólica y diastólica mayor en las personas que hicieron que en las que no hicieron ejercicio. Las cifras de HDL estaban por debajo de lo normal antes del ejercicio aumentaron significativamente con el ejercicio pero aún se mantuvieron por debajo de los valores de referencia, las HDL2 aumentaron significativamente, mientras las HDL3 descendieroncon niveles normales de apoA-I. Conclusiones Este trabajo muestra que el ejercicio aumenta las HDL totales, pero lo más importante es que modifica la subpoblaciones de HDL en una relación que favorece aquellas que parecen tener propiedades ateroprotectivas. Y la evidencia de la interrelación entre factores protectores, aporta nuevos argumentos para las acciones en salud pública, frente al riesgo cardiovascular y la hipertensión Arterial.


Objetive Determine the relationship of exercise with serum levels of apoA-I and HDL2 and HDL3, subpopulations in hypertensive individuals from the city of Armenia - Quindío. Methods The interventions were two months of exercise. Blood pressure was taken with the recommendations of the Ministry of Health of Colombia. HDL subpopulations were measured with the method of precipitate ionicand the apoA-I was measured using nephelometry of Bindig site. Results Descriptive and inferential statistics were used for data analysis. A total of 160 patients of whom 125 remained until the end of the project were gathered, that is, there was a 78.12 % retention, 28 % did the exercise. The analysis showed a highly significant reduction of systolic and diastolic blood pressure, higher in people who did exercise. The HDL were below normal before exercise, significantly increased with exercise but still remained below the reference values, the HDL2 increased significantly, while HDL3 decreased with normal levels of apoA-I. Conclusion This study shows that exercise increases the total HDL, but the most important is that exercise modified the HDL subpopulations in a relationship that favors those which seem to have ateroprotective properties. The evidence of the interrelationship between protective factors provides new arguments for public health actions against the cardiovascular risk and hypertension.
