Abstract

Polymorphisms in the promoter region of CD14 gene have been associated with asthma and atopy although the findings between cohorts have not been uniform. We aimed at investigating the association between CD14 gene (−1145G/A) polymorphism and bronchial asthma in Egyptian children. Genotyping of CD14 gene (−1145G/A) polymorphism was done by real-time PCR in 192 asthmatic children (atopic, n = 100 and non-atopic, n = 92) and 181 age- and gender-matched healthy children. Serum levels of total IgE were measured by ELISA. Skin prick test was performed on all patients. We found that the frequency of AA genotype was significantly higher in asthmatic children compared to healthy controls. Asthmatic children carrying GG genotype had a significantly lower prevalence of atopic asthma. Meanwhile, the “A” allele was significantly higher in atopic asthmatic children compared to healthy and non-atopic children. Moreover, atopic children carrying the “G” allele showed better asthma control. In conclusion, our findings represent an evidence for the role of CD14 gene (−1145G/A) polymorphism in childhood asthma and asthma control.
