The Effect of Maternal Age on Childhood Asthma

Some studies indicate that children born to younger mothers are at a higher risk of wheezing and asthma.  To investigate the maternal age associated with asthma in children, a case-control study on 310 asthmatic and 310 non-asthmatic children aged 3 to 4 years was organized during a one-year period.  A questionnaire was used to obtain information about the child’s personal susceptibility factor...

IL-23 Gene and Protein Expression in Childhood Asthma

Background: Asthma is the chronic inflammation of airways characterized by eosinophilic infiltration, mucus overproduction, airway hyper-responsiveness and airway remodeling. These changes are induced mostly by cytokines which are produced by T helper (Th) 2 cells. Recently, the role of interleukin-23 (IL-23) in the pathogenesis of adultallergic asthma has been studied. Objective: To explore IL...
