oral intake of mg in controlled asthmatic patients

Conditions: Bronchial Asthma

Summary: the goal of this clinical trial is to assess the efficacy of oral magnesium supplements in controlled asthmatic patients for proper effective asthma management to reduce frequency of asthma exacerbation \& to test the effect of oral magnesium supplementation on improvement of both clinical symptoms and lung functions in patients with bronchial asthma.. the main questions it aims to answer are: • can oral supplementation of magnesium play a role in decrease the number of bronchial asthma exacerbations , number of er visits , number of doctor visits and improve lung function ? researchers will compare patients on usual treatment according to gina guidelines 2024 group b and those taking oral magnesium together with the usual group a . participants will: * take oral magnesium treatment with usual asthma medications according to gina guidelines (2024) every day for 1year * visit the clinic once every 2 weeks for checkups and tests * keep a diary of their day and night symptoms and the number of times they had activity limitation due to asthma and the number of use reliever.

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 .
