Efficacy and safety of Tripterygium wilfordii hook F versus acitretin in moderate to severe psoriasis vulgaris: a randomized clinical trial.
BACKGROUND: Few clinical trials have evaluated the efficacy and safety of Tripterygium wilfordii Hook F (TwHF) compared with acitretin in psoriasis. We aimed to compare the efficacy and safety of TwHF compared with acitretin in the treatment of moderate to severe psoriasis vulgaris. METHODS: Adults with Psoriasis Area Severity Index (PASI) score ≥ 10 and psoriasis-affected body surface area ≥ 10% were randomized into a TwHF (20 mg, 3 times a day) or acitretin group (30 mg, once a day). The treatment course lasted for 8 weeks. Patients were assessed at baseline and at 2, 4, and 8 weeks. Laboratory tests were performed at baseline, week 4, and week 8. The data were analyzed using paired samples t-test or analysis of variance (ANOVA). RESULTS: A total of 115 patients was enrolled (58 TwHF; 57 acitretin). The median PASI score improved in the TwHF group by 50.4% and in the acitretin group by 42.7%. There was no significant difference in median PASI improvement between two groups at 2, 4, and 8 weeks. There was also no significant difference in PASI 25, PASI 50, PASI 75, and PASI 90 response between the two groups at 2, 4, and 8 weeks. There was a significant increase in the level of aspartate transaminase and triglycerides in the TwHF group (P = 0.026 and P = 0.011, respectively). In the acitretin group, there was a significant increase in the level of alanine transaminase, cholesterol, and high-density lipoprotein (P = 0.030, P < 0.01, and P < 0.01, respectively). CONCLUSIONS: There was no significant difference in treatment efficacy between the TwHF and acitretin groups within 8 weeks, but there were fewer treatment-related adverse events in the TwHF group.[1]References
