Background: Asthma is the most common chronic illness in childhood and really affects the everyday life of patients who suffer from it. Since asthma is a common disease, there is a great endeavour to achieve the most appropriate treatment option. Despite inhaled corticosteroids and leukotrien receptor antagonists both being routinely used in asthma treatment, specific immunotherapy is still questioned. There are numerous aspects affecting asthma-related quality of life, such as age; seasons; disease control and severity etc, which are well studied-apart from the type of treatment. With this study we aimed to stress the influence of asthma treatment on quality of life.
