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.
