Efficacy of Thunder-Fire Moxibustion In Treating Ankylosing Spondylitis of Kidney Deficiency And Governor Meridian Cold And Its Influence On Bone Metabolism:Study Protocol For A Randomized Controlled Trial
Abstract Background: Ankylosing spondylitis(AS) is a common chronic inflammatory spondyloarthropathy,.It is considered in Traditional Chinese Medicine(TCM) that the pathogenesis of AS is mainly due to Yang deficiency of kidney governor meridian and internal prosperity of cold evil. Thunder-fire moxibustion is a kind of moxibustions and characterized in abundance in drug composition, high heat radiation and strong penetration. Thunder-fire moxibustion on spinal segment of governor meridian in treating AS seems compatible with the main pathogenesis of kidney deficiency and governor meridian cold. The Trial aims to explore the efficacy of thunder-fire moxibustion in patients with AS of kidney deficiency and governor meridian cold and its influence on bone metabolism, through a prospective randomized trial. Methods: Sixty patients with AS of kidney deficiency and governor meridian cold will be recruited and randomly assigned to the treatment group (thunder-fire moxibustion three times a week plus basic treatment)and the control group (basic treatment) at the Center of TCM of Beijing Luhe Hospital Affiliated to Capital Medical University (Beijing, China), Each patient will be treated for 4 weeks.Primary outcome indexes will include efficacy of TCM syndrome,Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI),with observation once respectively prior to the treatment, 2 weeks post to the treatment, and at the end of the treatment. Secondary outcome indexes will include tumor necrosis factor-α(TNF-α) and receptor activator of nuclear factor-κ B ligand(RANKL), which will be determined once respectively before and after treatment.Side effects during the treatments will be recorded and analyzed as well. Inter-group comparison and analysis will be performed based on intention-to-treat set and per-protocol set. Discussion: This prospective randomized trial will help verify the efficacy of thunder-fire moxibustion in treating AS of kidney deficiency and governor meridian cold, discuss preliminarily its mechanism in treating this disease, and provide high-quality evidences for scientific researches on clinical treatment with thunder-fire moxibustion against AS.
