Abstract

Background: VITAMIN D has a potential to modulate inflammatory response against noxious particles in patients with CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD). The present study was conducted to determine the status of serum VITAMIN D in COPD versus healthy group.Methods: The patients presented to the outpatient pulmonary clinic of Ayatollah Rouhani Hospital, Babol Iran. Diagnosis of COPD was confirmed based on airflow limitation defined as FEV1/FVC ratio<70% and FEV1<80% of predicted. All eligible patients aged³40 years old entered the study. Pulmonary infection, tuberculosis, pleural effusion, congestive heart failure, pulmonary hypertension and embolism, restrictive airway disease, conditions leading changes in VITAMIN D metabolism and absorption were excluded. Serum 25-hydroxyVITAMIN D (25-OHD) was determined by electrocheminluminescence method and levels<20, 20-29, and³30ng/ml were considered as DEFICIENCY, INSUFFICIENCY, and sufficiency. In statistical analysis, the frequency of serum 25-OHD DEFICIENCY and INSUFFICIENCY in patients were compared regarding age of£50 or>50 years old. All patients were males and age and sex-matched controls were selected among healthy subjects accompanied COPD patients.Results: Ninety patients and 100 controls with respective mean (±SD) age of 64.8±11.7 and 62.6±11.7 years old (P=0.19) were studied. Compared with control, proportions of serum 25-OHD DEFICIENCY and INSUFFICIENCY in patients>50 years were higher and DEFICIENCY was lower (61.5% vs 87.5%, P=0.11).Conclusion: These findings indicate that a significant proportion of young COPD patients have insufficient serum 25-OHD. Regarding a positive relationship between 25-OHD and FEV1 in COPD, these findings highlight serum 25-OHD assessment in COPD for recognizing high risk patients.
