WHAT IS KNOWN AND OBJECTIVE: In this study, the effect of carvacrol (CAR) on pulmonary function tests (PFT), haematological indices and oxidant/antioxidant biomarkers in patients with sulphur mustard (SM)-induced lung disorders was examined.

METHODS: Twenty patients exposed to SM 27-30 years ago were divided into two groups and treated with either placebo (P) or CAR (1.2 mg/kg per day) (n = 10 for each group). Forced vital capacity (FVC), peak expiratory flow (PEF), total and different white blood cell (WBC), haematological parameters and oxidant/antioxidant biomarkers were measured at the baseline (step 0), one and two months (steps I and II, respectively) after starting the treatment.

RESULTS AND DISCUSSION: PEF was significantly increased in the CAR-treated group in step II compared to step 0 (P < .01). Total WBC (P < .01) and neutrophil (P < .05) count in the CAR-treated group were significantly decreased in the group in steps I and II (P < .01 for both cases) compared to step 0. The levels of thiol, superoxide dismutase and catalase in the CAR-treated group were significantly increased (P < .05 to P < .001) in steps I and II, but malondialdehyde significantly decreased in step II compared to step 0 (P < .01). The percentage of total and differential WBC, oxidant/antioxidant biomarkers, FVC and PEF values following a two-month treatment period were significantly improved in the CAR-treated group compared to the placebo group (P < .05 to P < .001).

WHAT IS NEW AND CONCLUSION: Two-month treatment with CAR reduced inflammatory cells and oxidant biomarkers, whereas increased antioxidant biomarkers and improved PFT tests in SM-exposed patients.
