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.

Effects of atorvastatin doses on serum level of procalcitonin and predictors for major adverse cardiovascular events in patients with acute myocardial infarction: a pilot study and post hoc analysis

“…In addition, the serum procalcitonin levels in the 80/40-mg group were significantly lower than those in the other two groups at 3 days after PCI. For patients with bronchitis or pneumonia, low-dose atorvastatin treatment (20 mg or 40 mg) did not significantly change the procalcitonin level compared to placebo [34,35]. It is suggested that the early application of atorvastatin can inhibit the inflammatory response, high-dose of atorvastatin before PCI has a strong anti-inflammatory effect, and the anti-inflammatory effect of atorvastatin is dose-dependent.…”
