The effect of atorvastatin on inflammatory markers in sulfur mustard gas induced bronchitis: a randomized double-blinded, placebo-control clinical trial.


ABSTRACT:

Background

This study was performed to evaluate the anti-inflammatory effect of atorvastatin in patients with chronic bronchitis, exposed to sulfur mustard gas.

Methods

In this randomized double-blinded clinical trial we recruited patients with chronic bronchitis after exposure to sulfur mustard gas. Ninety men 45-75 years old diagnosed with chronic bronchitis after exposure to mustard gas during the Iran-Iraq war, were randomly assigned to receive either atorvastatin (40 mg) or placebo once a day for 3 months. The interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), procalcitonin, highly sensitive CRP and COPD assessment test (CAT) score was compared at baseline and after 12 weeks.

Results

After consuming atorvastatin for 12 weeks, IL-6 level (mean difference [95%CI]; 0.2 [- 0.05, 0.5]), TNF-α (mean difference [95%CI]; - 0.07 [- 0.2, 0.07]), high sensitive CRP (mean difference [95%CI] - 0.1 [- 1.2, 0.9]), and procalcitonin (mean difference [95%CI]; 0.003 [- 0.02, 0.03]) did not change significantly. However, in the placebo group, only IL-6 (mean difference [95%CI]; 0.6 [0.2, 1.05]) decreased significantly after 12 weeks, but levels of high sensitive CRP (mean difference [95%CI]; - 0.3 [- 1.4, 0.8]) TNF-α (mean difference [95%CI]; - 0.2 [- 0.34, - 0.06]) and procalcitonin (mean difference [95%CI]; 0.02 [- 0.001, 0.04]) did not change significantly. After 12 weeks, the mean differences in TNF- α, IL-6 level, high sensitive CRP, procalcitonin, and CAT score did not significantly differ between the two groups.

Conclusions

The administration of 40 mg atorvastatin for 3 months did not significantly change the inflammatory markers or the quality of life of patients exposed to mustard gas with chronic bronchitis.
