Brief Summary

Asthma is a disease that represents a public health problem worldwide, there are several barriers, especially in pediatric patients with this disease, them, prevent the adequate control of their condition, in addition every day there are new processing aids for this entity; within these novel research we founded the relationship between decreased vitamin D serum levels and his role in the regulating of the immune response, also this relationship in the pathophysiology of this disease and responses in the event of infectious diseases of the respiratory tract which can exacerbate symptoms in pediatric patients. We have been some of clinical trials with the aim of improving serum levels of vitamin D in asthmatic patients, however, these studies have different sources of bias and thus far there is no solid evidence that favors or denies the relationship between asthma and vitamin D, this paper aims to help generate this evidence to improve clinical management of these patients and their lung function and increase the free time crisis. In this trial two study groups which are divided for each of the interventions described below: Group low supplementation dose: 1 tablet of 400 IU was administered every 24 hours via oral, regardless of time or if it is before or after food, preferably in the morning to improve adherence to treatment, will be completed one year of treatment without suspension. Group high supplementation dose: 1 tablet of 1600 IU should be administered every 24 hours via oral, regardless of time or if it is before or after food, preferably in the morning to improve adherence to treatment, will be completed one year of treatment without suspension thereof.
