Abstract:

Objective

To observe the effects of fluticasone furoate/vilantrol (FF/VI) on lung function, peripheral blood Th1/Th2 drift, glutathione peroxidase (GSH-PX), malondialdehyde (MDA) and 8-hydroxy-2′-deoxyguanosine (8-OHdG) levels in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).

Methods

A total of 100 patients with acute exacerbation of COPD were selected from the hospital and randomly divided into two groups by number table method. The control group were given conventional treatment. On the basis, the experimental group were additionally treated with FF/VI. Lung function indexes [the ratio of residual volume to total lung capacity (RV/TLC%), the percentage of forced expiratory volume in one second in the predicted value (FEV1%)], levels of GSH-PX, MDA and 8-OhdG and adverse reactions were compared between the two groups before and after treatment. 50 healthy people were selected and included in the health group at the same time. The situation of peripheral blood Th1/Th2 drift [interferon γ (INF-γ), interleukin 4 (IL-4) and IL-4/INF-γ] in the experimental group and the control group was analyzed.

Results

After treatment, the FEV1% in the experimental group was significantly higher than that in the control group (P<0.05), and the RV/TLC% was significantly lower than that in the control group (P<0.05). Before treatment, INF-γ and IL-4 were significantly higher in the experimental group and the control group than in the healthy group (P<0.05), while INF-γ/IL-4 was significantly lower than the healthy group (P<0.05). After treatment, INF-γ and IL-4 in the experimental group and the control group decreased significantly (P<0.05), and INF-γ/IL-4 increased significantly (P<0.05). INF-γ and IL-4 in the experimental group were significantly lower than those in the control group (P<0.05), and INF-γ/IL-4 was significantly higher than the control group (P<0.05). After treatment, the GSH-PX level in the experimental group was significantly higher than that in the control group (P<0.05), and the levels of MDA and 8-OhdG were significantly lower than the control group (P<0.05). There was no significant difference in the overall incidence of adverse reactions between the two groups (P>0.05).

Conclusion

FF/VI can effectively regulate the peripheral blood Th1/Th2 drift in patients with acute exacerbation of COPD, improve the expression levels of GSH-PX, MDA and 8-OhdG, and enhance the immune capacity, with antioxidant effect. It also can promote the recovery of lung function.
