Clinical benefits of Seven years treatment with Omalizumab in severe uncontrolled asthmatics.

Severe asthma is characterized by inadequate symptom control and by high rate of inflammation despite high doses of steroids. Omalizumab, a recombinant humanized monoclonal anti-IgE, provides a new therapeutic strategy in severe allergic asthma. Aims. This study was aimed to assess whether long-term treatment with omalizumab improved clinical control in severe asthmatics. Methods. We investigated omalizumab effects on asthma outcomes evaluating seven severe allergic asthmatic patients who were treated for 7 years with add-on omalizumab. Number of exacerbations, use of antibiotics, additional asthma medications (systemic steroids, nebulized steroids and bronchodilators), and spirometry were analyzed before and after omalizumab treatment. Results. Omalizumab was well tolerated by all the studied patients. It improved FEV1 and FEV1/FVC ratio and reduced symptom score, asthma exacerbations, use of antibiotics, and use of nebulized steroids, bronchodilators, and oral corticosteroids. These effects were evident after 4 years of treatment and more pronounced after 7 years of treatment. Conclusions. This study underlines the utility of a long-term treatment with omalizumab to improve asthma clinical outcomes in severe asthmatics.
