Asthma is a chronic inflammatory airway disease characterized by variable airway obstruction and bronchial hyperresponsiveness. There are many factors affecting the development and severity of childhood asthma such as genetic predisposition, atopy, environmental factors, obesity, diet, socioeconomic status, and infectious triggers. In the present study we aimed to investigate the frequency of Mycoplasma pneumoniae, Chlamydia pneumoniae, and Helicobacter pylori infections in asthmatic children. We investigated also whether there is a relationship between these agents and asthma attacks.
