Zafar Majeed Babar, Mazhar Hussain, Sadia Abdul Majeed


Background and Objective: Vitamin D deficiency has strong association with various respiratory disorders in which bronchial asthma is one of them. The objective was to determine the efficacy of vitamin D supplementation in cases with bronchial asthma.

Methods: This case control study was conducted at private clinical set up of district, Rahim Yar Khan from August to October 2016 in which 100 cases of bronchial asthma were randomly divided into Group-A and Group-B each contained 50 patients. Group-A was given placebo and Group-B with vitamin D in a dose of 50,000 units per day orally. Both the groups were followed in terms of improvement in FEV1 at 1, 2 and 3 months.

Results: There was no significant difference in both groups in terms of BMI and duration of asthma at start of study. The mean pre treatment vitamin D level of Group-A was 14.23±1.66 and of Group-B, 15.30±2.05 ng/dl (p= 0.23). FEV1 in pre treatment Group-A was 64.35±3.16 and of Group-B was 62.35±2.16 with p= 0.95. There was no significant difference in terms of FEV1 in both the groups at one month (p= 0.32). While at two months it was significantly higher in Group-B with p= 0.04. At 3 months the final outcome was seen where the post treatment FEV1 in Group-A was 66.13±2.75 and in Group-B, 75.15±2.04 with p value of 0.001.

Conclusion: Vitamin D supplementation improves FEV1 significantly at two months and these can be even highly significant if it is extended up to 3 months.
