To see the levels of Vitamin D in patients of asthma

Background: asthma is a condition,which is increasing worldwide,since 1960.there are several known aggravating factors for asthma like environmental pollution,childhood allergies.etc. but some contributing factors are still in grey zone,like vitamin d in these patients. vitamin d plays an important role in immunomodulation and in inhibition of release of immunoglobulins and interleukins by bcells and t cells respectively. so its deficiency may contribute to severe asthma. to see the association between vitamin d and severity of asthma we conducted a cross sectional observational study at lgh. study design: it was a cross sectional observational study. method: 50 patients of chronic stable asthma and 50 controls were taken. their history was taken and systemic examination was done and level of 1,25 dihydroxycholecalciferol was done. result: a significant correlation was found between low levels of vitamin d and control of asthma. conclusion: vitamin d deficiency may be associated with poor control of asthma,which warrants further studies to be done in asthmatic patients by supplementing them with vitamin d and then seeing the results.
