Omalizumab is a monoclonal anti-immunoglobulin E antibody currently only approved for use in severe, refractory asthma. In recent years, many authors have reported satisfactory results with omalizumab in patients with difficult-to-treat chronic urticaria. As a result, clinical trials were undertaken to broaden the indication of omalizumab to include chronic urticaria, and the drug was recently ...

BACKGROUND Eosinophilic esophagitis (EoE) has been defined as "asthma of the esophagus" for the large number of similarities between the two diseases. Omalizumab is an anti-Immunoglobulin E (IgE) antibody currently approved only in allergic IgE-mediated severe persistent uncontrolled asthma and in chronic spontaneous urticaria unresponsive to antihistamines, but it has been tried in other disea...

BACKGROUND To evaluate long-term effectiveness of omalizumab in 'real-life' setting of Thai asthmatic patients. METHODS We conducted multi-center, observational study in severe asthma patients who received omalizumab in Thailand. Outcomes were asthma exacerbation (hospitalization and ER visit), asthma control test (ACT), and daily ICS dose. Data were evaluated at baseline, 16 Week, and 52 Wee...

Background Anti-IgE treatment represents a major breakthrough in the therapeutic management of severe allergic asthma. To date, omalizumab is the only biological drug currently licensed as add-on therapy in children aged > 6 years with moderate-to-severe and severe allergic asthma uncontrolled after treatment with high dose of inhaled corticosteroids plus long-acting inhaled beta2-agonist. The ...

BACKGROUND Omalizumab is licensed as add-on therapy for patients with severe allergic asthma. Response is in most studies scored by the physician's global evaluation of treatment effectiveness (GETE). A good clinical and validated parameter for treatment response is currently missing. Also, there are no established criteria for identifying patients who will respond to omalizumab based on pre-tr...

The treatment of antihistamine and steroid resistant Chronic Idiopathic Urticaria (CIU) during pregnancy poses a challenge due to teratogenicity of immunosuppressants. Omalizumab is a recently FDA approved therapy for CIU and is classified as pregnancy category B. We present an initial series of subjects treated at a tertiary care center for antihistamine and steroid resistant CIU with omalizum...

Summary The first case of disappearance of apple-induced oral allergy syndrome in a birch pollen-allergic patient following omalizumab treatment is reported. This observation in a case of type 2 food allergy suggests that omalizumab is potentially an effective preventive treatment for patients with severe, type 1 food allergies.

Omalizumab is an anti-human IgE humanized monoclonal antibody produced against CƐ3 domain of the Fc fragment of IgE molecule. Omalizumab suppresses the effector roles of IgE by preventing binding to high-affinity receptors (FcεR1) on allergy-related immune effector cells and blocking mast cell or basophil mediator release.4 Based on this mechanism of action, Omab also provides symptomatic relie...

Introduction In Canada the use of Omalizumab is restricted to patients with moderate to severe allergic asthma. However there are some cases reports showing its effectiveness in other conditions like chronic urticaria, ABPA and patients with nasal polyps and asthma. Although there are also reports of using omalizumab in patients with cystic fibrosis and ABPA, there are not controlled trials con...
