Oral Intake of Mg in Controlled Asthmatic Patients

Asthma is one of the main non-communicable chronic diseases and affects a huge portion of the population. It is a multifactorial disease, classified into several phenotypes, being the allergic the most frequent. The pathophysiological mechanism of asthma involves a Th2-type immune response, with high concentrations of allergen-specific immunoglobulin E, eosinophilia, hyperreactivity and airway remodeling. These mechanisms are orchestrated by intracellular signaling from effector cells, such as lymphocytes and eosinophils. Ion channels play a fundamental role in maintaining the inflammatory response on asthma.The mainstay of management is a beta-agonist and corticosteroids inhaler. However, new investigations into the pathogenesis of the disease are emerging. For example, many reports have observed that low blood levels and low dietary intake of magnesium are factors that possibly contribute to the development of asthma. In addition, low levels of magnesium have been detected in asthmatics compared with non-asthmatics, especially those that have presented to the emergency department with exacerbations.The role of intravenous and inhaled magnesium in the management of acute asthma has been extensively studied and the guidelines are well established. IV or inhaled routes can be used as a last resort for severe, persistent asthma that fails to respond to conventional treatment. Nevertheless, oral magnesium is not included in these guidelines. so on, this study has these objectives : To detect any disturbance in magnesium blood level in patients with controlled bronchial asthma . 2. To compare frequency of asthma exacerbations in asthma controlled patients in patients who will be treated with oral magnesium supplementations and those who will not receive it . 3. To determine if oral magnesium supplementation is an adjunctive from the start for adequate effective control of bronchial asthma. 4. To determine the relationship between oral magnesium supplementation and FEV1 improvement .
