Omalizumab rescue therapy in refractory status asthmaticus.

Introduction: Refractory status asthmaticus (RSA) is a severe, life-threatening form of asthma exacerbation that persists despite aggressive treatment with systemic corticosteroids, bronchodilators, and other supportive measures. Omalizumab, a monoclonal antibody that targets IgE, has been approved for treating severe allergic asthma and is effective in reducing the frequency of exacerbations and improving asthma control. Limited evidence exists regarding the use of Omalizumab in RSA, but some studies have suggested that it may have a role in its management.
