Previous studies showed Rhodiola had anti-inflammatory effects, but no study of Rhodiola as an immunomodulator in patients with COPD has been reported. In this study, patients with COPD took Rhodiola crenulata 500 mg (n=38) or placebo (starch/phosphate buffered saline) (n=19) daily for 12 weeks and were compared with untreated, age- and sex-matched 79 non-COPD control (79 healthy smokers). The results showed that serum levels of IL-2, IL-10 and IFN-γ in patients with COPD before treatment are significantly higher than levels in non-COPD controls (p < 0.05). A significant decrease in IFN-γ was seen in the Rhodiola treatment group (p < 0.05) but not in the placebo group (p> 0.05). The effects of Rhodiola treatment in patients with COPD were shown to decrease the IFN-γ concentration and CD8+ count but increase the expressions of CD4+CD25+FOXP3+ and CD4+CD25+CD45+FOXP3+ in the blood significantly (p < 0.05). The results suggested that Rhodiola treatment had beneficial anti-inflammation effects, lower COPD assessment test(CAT) score and decreased high sensitivity C- reactive protein in patients with COPD (p< 0.05). This is the first trial using Rhodiola as a complementary therapy in patients with COPD. T cells play an important role in the pathogenesis of COPD through the increased expression of CD8+ T cells and IFN-γ and may be a viable target for potential therapy.慢性阻塞性肺病細胞激素紅景天T細胞COPDcytokineRhodiolaT cellsthesis
