The improvement of FEV-1 reversibility is a
cumulative result of 4 factors
• decreased IL-4, enhances inhibition of IgE production.
• decreased IL-5, enhances inhibition of eosinophil
maturation in the stem cell, chemo taxis, and prolonged life
span.
• increased IFN-γ enhances isotype switching of
immunoglobuline production in favor of IgG subclass
instead of IgE.
• increased IL-2 enhances the affinity maturation and
differentiation of B cells giving rise to the generation of B
memory cells and antibody secreting plasma cells
producing IgG.

Conclusion
Immunotherapy in asthmatic children
results in elevation of IFN-γ and IL-2, diminish
IL-4 and IL-5.
Addition of inhaled corticosteroid to
immunotherapy results in marked attenuation
of IL-5 correlates with greater elevation of
IL-2 and play an important role in the
modulation of immune response resulting in
the improvement of FEV-1 reversibility.

•Reduce development of Rhinitis to
asthma
•Reduce developing new sensitization
•Prevent allergic children from going on
to develop asthma
•Rhinitis symptom seem to show more

1. The primary mechanism of action is a
shift in the balance of Th-1 and Th-2
cytokine expression in the allergen-
challenged site.
2. Allergen IT is highly form of treatment
of IgE mediated diseases.
3. Highly effective for allergic rhinitis and
hypersensitivity to wasp and bee
venom.
4. Consideration for primary use in
asthma is still controversial in regards
the potential development of adverse
event.
