Sliding Cupping Therapy Matches NBUVB in Psoriasis Severity Reduction at 8 Weeks
This randomized controlled trial evaluated the efficacy of sliding cupping therapy compared to narrowband ultraviolet B (NBUVB) therapy in 60 patients with plaque psoriasis. Participants were randomized to receive either sliding cupping or NBUVB treatment three times per week for eight weeks. The primary endpoint was the percentage reduction in Psoriasis Area and Severity Index (PASI) score at week 8. Results showed a mean percentage reduction in PASI of 62.4% (95% CI, 54.9-69.8) in the sliding cupping group and 66.9% (95% CI, 59.6-74.2) in the NBUVB group, with no significant difference between the groups (P=.526). Secondary endpoints, including Physician's Global Assessment (PGA), body surface area, and quality of life measures, also showed no significant differences between the groups at weeks 0, 4, 8, and 12. The total response rates were 69.23% for sliding cupping and 79.17% for NBUVB, which was not statistically significant (P=.526). Safety profiles were similar between the two treatments, with no significant adverse events reported. These findings suggest that sliding cupping therapy may be a viable alternative to NBUVB for managing plaque psoriasis, offering similar efficacy and safety.
