[Moxibustion on plaque psoriasis of blood stasis: a randomized controlled trial].

ABSTRACT

OBJECTIVE: To observe the short-term and long-term effects of moxibustion on plaque psoriasis of blood stasis, and to compare the curative effect between moxibustion and calcipotriol ointment. METHODS: A total of 80 patients with plaque psoriasis of blood stasis were randomly divided into an observation group (40 cases, 2 cases dropped off) and a control group (40 cases, 4 cases dropped off). Both groups were given routine medical vaseline topical emollient basic treatment. In the observation group, moxibustion was applied to ashi point (target skin lesions), Zusanli (ST 36), Xuehai (SP 10) and Qihai (CV 6) for 30 min each time, 3 times a week. The control group was treated with calcipotriol ointment (0.25 g each time, once in the morning and evening) on the target skin lesions. Both groups were treated for 8 weeks. The psoriasis area and severity index (PASI) score before and after treatment, main clinical symptoms of TCM score and dermatology life quality index (DLQI) score before and after treatment and 3 and 6 moths follow-up were observed in the two groups; the clinical efficacy after treatment was evaluated and the recurrence rates of the two groups were followed up for 3 and 6 months after treatment. RESULTS: After treatment, the PASI scores in the both groups were lower than before treatment (P<0.01). After treatment and 3 and 6 months follow-up, the main clinical symptoms of TCM scores and DLQI scores of the two groups were lower than those before treatment (P<0.05), and at 3 and 6 months follow-up, those in the observation group were lower than the control group (P<0.01). There was no statistically significant difference between the observation group and the control group in overall effective rate and target skin lesion effective rate (P>0.05). At 3 and 6 months follow-up, the overall recurrence rate and target skin lesion recurrence rate in the observation group were lower than those in the control group (P<0.05). CONCLUSION: Both moxibustion and calcipotriol ointment have good short-term effects on plaque psoriasis of blood stasis. Moxibustion has more advantages in reducing the recurrence rate of psoriasis, improving the main clinical symptoms of TCM and quality of life.
