Background: The aim of this study was to determine the mean of the
serum level of vitamin D in chronic obstructive pulmonary disease (COPD)
patients referred to Rasoul-E-Akram Hospital, Tehran, Iran in 2010-11.
Methods: In this sectional study 56 patients with COPD were
recruited. The COPD condition was confirmed in these patients following
spirometry. Serum vitamin D level of all patients was measured and categorized
according to the 5 stages of 0,1,2,3, and 4 suggested by Global Initiative on
Obstructive Lung Disease (GOLD). The data were analyzed using SPSS v. 18.
Results: The mean age of patients was 68.1 ± 10.3. About%76 of
patients were men. The study indicated that%85.1 of the patients were suffering
from vitamin D deficiency with the level less than 30 mg /dl. Also, it was
indicated that there is a direct and linear relation between serum vitamin D
level and forced expiratory volume in one second (FEV1) volume(p= 0.03), (B=
0.4).
Conclusion: The study demonstrated that vitamin D deficiency in
COPD patients is highly prevalent. Thus, diagnostic examinations of vitamin D
deficiency and on time treatment can prevent from many related problems in
these patients.
