Clinical effect analysis of ankylosing spondylitis treated by Chinese medical syndrome differentiation

Objective To evaluate the curative effect and safety of Bushen Qiangji Decoction(BQD) and Qingre Qiangji Decoction(QQD) in treating ankylosing spondylitis(AS) patients,and to verify the clinical utility of AS syndrome differentiation and treatment scheme [Shen-deficiency induced stasis obstruction syndrome(SDISOS) and dampness-heat obstruction syndrome(DHOS) being two basic syndrome types,Shen invigorating blood activating method(SIBAM) and heat clearing dampness resolving method(HCDRM) being two basic treatment methods].Methods Totally 354 AS patients of SDISOS and DHOS were randomly assigned to the treatment group and the control group using a multi-center randomized,positive drug parallel-controlled clinical trail.Patients in treatment group were treated by BQD or QQD according to syndrome typing,while those in the control group took Sulfasalazine enteric-coated tablet(SECT),24 weeks as one therapeutic course.After treatment,the clinical efficacy was evaluated by using ASAS20 standard(set by Asessment in Ankylosing Spondylitis working group),Chinese medical efficacy evaluation standards,and BASDAI,BASFI,BASMI,night-pain index,spinal pain index,PGA,C-reactive protein(CRP),and erythrocyte sedimentation rate(ESR).Results After 24 weeks of treatment by BQD or QQD,ASAS20 standard rate was 86.75% in the treatment group,and the total effective rate of Chinese medical syndrome was 85.47%.They could significantly reduce patients' integrals of Chinese medical syndrome,BASDAI,BASFI,BASMI,night-pain index,spinal pain index,and PGA(all P 0.01).Conclusions QQD and BQD got confirmable clinical effects in treating AS,providing strong evidence of evidence-based medicine for syndrome differentiation and treatment of AS.
