Introduction
Asthma is a common chronic inflammation that needs a lot of health care and it has a lot of high risks (1). Asthma is one of 10 most common situation that restricted activities (2). It seems that vitamin D supplements are associated with a reduction in mortality (3).
Studies show that low levels of vitamin D can lead to deformation of the airways, release cytokines and increase the smooth muscle lining of the bronchi. Vitamin D can potentially increase the answer of glucocorticoids in steroid resistant asthma (4).
There are at least two important aspects of the relationship between vitamin D and asthma. the first claim is that lack of vitamin D in utero and early life is associated with an …show more content…
Upper respiratory infection, acute One of the most common diseases in children before school and children in early for an average of 6 to 8 times a year are affected in any case likely Effects such as acute otitis media, 15% to 30%, sinusitis 10 to 13% and less than 1% of community-acquired pneumonia River (7).
In a recent survey the role of vitamin D in the immune system fight against the pathogen is unknown. Vitamin D as a hormone that regulates a key role in the differentiation of lymphocytes is immune. The role must be appropriate concentrations. A study that has shown a lack of vitamin D, we have suppressed immune delayed response. Vitamin D in patients with AIDS has a direct relationship to the number of the CD4 ratio is inversely related to mortality rate (8).
Examination of a variety of subclinical vitamin D deficiency indicates that the increased risk of pneumonia and asthma attacks have increased hospital stay (9).
Recent epidemiologic studies of the association between vitamin D deficiency and an increased incidence of respiratory infections clearly show
