Background: The effects of serum vitamin D levels on its evolution or its severity have been widely researched, however, with conflicting results. This study was designed to evaluate the relation between serum Vitamin D levels and pulmonary function tests in asthmatics of Vitamin D deficient population.

Methods: This was a prospective cross-sectional study on healthy adults and asthmatic patients. Standard spirometry and measurements of serum 25 hydroxy Vitamin D were performed for all participants.

Results: Forty asthmatic patients and 40 healthy controls were tested. The mean age of participants was 42.86 ± 1.6. High prevalence of Vitamin D deficiency was found in both the asthmatic/control groups. No significant correlation was found between serum Vitamin D levels and spirometry parameters in either of the groups (p=0.83).

Conclusions: Serum levels of 25 hydroxy Vitamin D were not correlated with the severity of asthma as evaluated by pulmonary function tests in asthmatics.
