Allergy status in children tends to differ according to asthmatic phenotype of parents, particularly mothers. Mother's asthmatic phenotype stipulates for differences in structure and time of allergy onset in children.Purpose: To study the influence of maternal asthma phenotype on children's allergy status.Methods: We evaluated the allergy status in children from birth to 7 years of age born from 117 asthmatic mothers with regard to their asthma phenotypes; 88 (75.2%) mothers had early onset asthma phenotype (defined as asthma developing before 16 years of age), 29 (24.8%) – late onset phenotype.Results: The prevalence of allergic asthma and other allergic forms (allergic rhinitis and atopic dermatitis) in children by 7 years of life differed (p<0.001, binomial test) depending on the onset asthma phenotypes of mothers. Children born from mothers with early onset asthma phenotypes will be at higher asthma and others allergic forms risk (OR=3,04 [CI: 1.013-9.132]).Conclusions: Maternal asthma phenotype influences the onset and structure of allergy in children. Understanding of underlying asthma genesis is needed for protective measures and prognosis of the diseases in children. ER -
