Omalizumab with allergen immunotherapy in respiratory & food allergy.

Allergen Immunotherapy (AIT) is the only disease modifying treatment option for patient with IgE mediated allergic disorder. Conventional subcutaneous immunotherapy is associated with adverse events during build-up and maintenance phase but cluster allergen immunotherapy with monoclonal anti-IgE antibody (omalizumab) has complementary and synergistic effect. Omalizumab plus AIT can significantly enhance the efficacy, safety, and steroid-sparing effect of AIT by increasing target maintenance dose (TMD) and sustained unresponsiveness (SU) to allergen while decreasing the adverse events and severe systemic reactions. This review aims to highlight that combination of omalizumab plus AIT is superior than AIT alone.
