Official Title: Assessment Of Vitamin D Role In The Pathogenesis Of Asthma In Vitamin D Resistent Patients
Brief Summary:
Research Title: Evaluation of airway reactivity, allergy and inflammatory mediators in exhaled breath condensate in vitamin D resistant rickets.
Aim: To assess the effect of absence of vitamin D receptors on airway reactivity, allergy and inflammatory mediators in exhaled breath condensate in a prospective study evaluating patients with vitamin D resistant rickets and in healthy controls.
Sample size: 40 participants in the two groups. Primary end point: Airway reactivity as assessed by methacholine challenge test.
Secondary outcome parameters: All other parameters are the secondary end points.
