Objective: To observe the clinical effect of Wenhua Juanbi Recipe (WJR) in treating rheumatoid arthritis (RA), its effects in reducing the dosage of Western medicine used and stabilizing condition of disease, as well as its influences on peripheral blood levels of tumor necrosis factor alpha (TNF-alpha), interleukin 1beta (IL-1beta) and anti-cyclic citrullinated peptide antibody (anti-CCP), for the sake of exploring its preliminary acting mechanism.
Methods: One hundred patients with RA were randomly assigned to 2 groups, the control group and the treated group, 50 in each group. All were treated with oral administration of methotrexate (MTX,7.5 mg per week), sulfasalazine (0.5 g, tid) and meloxicam (Mobic, 7.5 mg, bid), but to the treated group WJR was given additionally. The therapeutic course for both groups was 3 months. Clinical effect, changes of symptoms and physical signs, dosages of western medicines used, and laboratory indices in 2 groups after treatment were observed, and cases of relapse 3 months after treatment were figured out.
Results: The total effective rate in the treated group was higher than that in the control group (88.0% vs 76.0%, P<0.05). The improvements in scores of symptoms and signs [joint pain (0.61 +/- 0.59), swelling (1.49 +/- 1.20), tenderness (0.90 +/- 0.69), movement (0.68 +/- 0.62), griping strength (68.56 +/- 6.50) mm Hg, morning stiff time (23.26 +/- 9.26) min], and in levels of laboratory indices (TNF-alpha, IL-1beta, anti-CCP, RF, ESR, CRP, PLT and Ig) in the treated group after treatment were significantly superior to those in the control group (P<0.05 or P<0.01). The dosages of MTX [(82.11 +/- 11.35) mg vs (94.75 +/- 10.23) mg] and meloxicam [(108.85 +/- 16.13) mg vs (189.63 +/- 18.44) mg] used, and the relapse rate in the treated group were lower significantly (P<0.05, P<0.01) than those in the control group respectively.
Conclusions: Effect of combined therapy of WJR and Western medicines is superior to that of using Western medicines alone in treating RA; WJR can reduce the dosages of Western medicines used and the relapse rate, as well as stabilize the condition of illness. It has the effects of immune regulating and anti-inflammatory reaction. Its mechanism for treating RA is possibly the inhibition on cytokines of TNF-alpha and IL-1beta.
