Every child with asthma who remain symptomatic despite the therapy, must be carefully evaluated.
First, the diagnosis of asthma must be confirmed, and confounding or exacerbating factors like ongoing allergen presence or additional lung diseases must be evaluated and treated.
There are number of conditions that can mimic or coexist with asthma.
One of these condition is the allergic rhinitis.
Exposure to allergens in sensitized children or cigarette smoke can cause ongoing poorly controlled symptoms and steps to reduce exposure will help to improve control.
A combination of intranasal steroid and anti- histamine may reduced asthma exacerbations (attacks of worsened asthma), and Leukotriene receptor antagonists are effective in treating both, asthma and rhinitis.
There is a clinical data about beneficial effect of subcutaneous immunotherapy in children with allergy and asthma.
Young patients with rhinitis receiving SIT are less likely to develop subsequent asthma or new allergic sensitivities.
