RESUMEN
Introducción:
La identificación de las bases genéticas del asma puede contribuir al descubrimiento de una terapia antiasmática efectiva.Objetivo:
Estimar la asociación entre polimorfismos del receptor beta2-adrenérgico (RB2A) y el asma nocturna en niños egipcios.Métodos:
Se genotiparon los polimorfismos de RB2A Gly16 y Glu27 en 200 niños egipcios (90 con asma nocturna y 110 controles sanos), mediante la técnica de la reacción en cadena de la polimerasa.Resultados:
El genotipo homozigoto (Gly16) incrementa el riesgo de padecer asma nocturna (OR 3.2, 95% CI, 1.3-7.7) (p=0.003) y el alelo Gly se asocia significativamente con el riesgo de padecer asma nocturna (OR 1.8, 95% CI, 1.2-2.8).Conclusión:
Este estudio demuestra una asociación de polimorfismos Arg/Gly del RB2A con el asma nocturna y una falta de asociación del polimorfismo Gln/Glu con dicho tipo de asma (AU)ABSTRACT
Background:
Identification of the genetic basis of asthma may contribute to the discovery of effective asthma drugs.Objective:
Our aim was to estimate the association between B2 adrenergic receptor (ADRB2) polymorphisms and nocturnal asthma in Egyptian children.Methods:
ADRB2 polymorphisms Gly16 and Glu27 were genotyped in 200 Egyptian children (90 with nocturnal asthma and 110 healthy controls) using allele-specific polymerase chain reaction.Results:
The homozygous (Gly16) genotype significantly increased the risk of nocturnal asthma (odds ratio [OR], 3.2; 95% CI, 1.3-7.7; P=.003), as did the Gly allele (OR, 1.8 95% CI, 1.2-2.8).Conclusions:
Our study demonstrated that nocturnal asthma was associated with ADRB2 Arg/Gly polymorphisms but not with ADRB2 Gln/Glu polymorphisms (AU)
