Efficacy of herb-separated moxibustion combined with sulfasalazine enteric-coated tablets for ankylosing spondylitis with cold-dampness obstruction type

Abstract

To compare the clinical efficacy between herb-separated moxibustion and conventional moxibustion on ankylosing spondylitis (AS) based on oral administration of sulfasalazine enteric-coated tablets. A total of 64 patients with AS of cold-dampness obstruction type were randomly divided into an herb-separated moxibustion group and a conventional moxibustion group, 32 cases in each one. Based on oral administration of sulfasalazine enteric-coated tablets, the patients in the conventional moxibustion group were treated with moxibustion at the area with Dazhui (GV 14) to Changqiang (GV 1) as center and about 10 cm in width; the moxibustion was given for 1 hour. In the herb-separated moxibustion group, the gauze was soaked in the medicinal liquor and ginger juice, and placed on the same moxibustion area as the conventional moxibustion group, followed by moxibustion for 1 hour. The treatment in the two groups was given once a week, three treatments constituted a course and totally three courses were given. The symptom quantification score, occipital-wall distance, Schober test, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels were observed before and after treatment in the two groups, and the clinical efficacy was evaluated. Compared before treatment, the symptom quantification score, occipital-wall distance, CRP and ESR levels were lower but the Schober test was higher after treatment in the two groups (all P<0.05). The symptom quantification score, Schober test, CRP and ESR levels in the herb-separated moxibustion group were superior to those in the conventional moxibustion group (all P<0.05), but no significant difference was observed on occipital-wall distance (P>0.05). The total effective rate was 90.0% (27/30) in the herb-separated moxibustion group, which was higher than 73.3% (22/30) in the conventional moxibustion group (P<0.05). The herb-separated moxibustion combined with sulfasalazine enteric-coated tablets has significant efficacy for AS with cold-dampness obstruction type, which could obviously relieve pain symptoms, improve occipital-wall distance, Schober test and other physical signs, and improve the quality of life.
