Résumé
OBJECTIVE: The objective of this systematic review was to prepare for evidence-based recommendations on the use of vitamin D analogues, and their combination with topical steroids in psoriasis. METHODS: Literature systematic review performed in May 2011. The Cochrane, PubMed and Embase databases were systematically searched with different combinations: including Psoriasis AND calcipotriol expanded to all vitamin D analogues. To assess efficacy across studies, we used two predefined criteria to account for the numerous endpoints found in the literature, 'Treatment success' corresponding to 90% improvement in severity and 'Satisfactory response' corresponding to 75% improvement. We conducted a meta-analysis comparing the efficacy of vitamin D analogues plus topical steroids (VDS) vs. vitamin D analogues alone (VD). To determine the relative cost-efficacy of the topical drugs available on the market, cost/efficacy ratios were calculated for each product according to the approved therapeutic regimen. RESULTS: 51 articles were selected. The application duration varied between three to 52 weeks across studies. VD as monotherapy had a satisfactory response rate between 22% to 96% and a treatment success rate ranging from 4% to 40%. VDS had a satisfactory response rate between 35% to 86% and a treatment success rate ranging from 27% to 53%. A meta-analysis found a probability of success twice higher with VDS than with VD in adult plaque psoriasis. The cost/efficacy ratio was evaluated as 1.2-1.8 times higher for VDS than for VD. CONCLUSION: VDS is twice more effective than VD and displays a better cost per success. Additional studies are needed to clarify maintenance treatment, impact on quality of life, treatment of non-plaque psoriasis. It will be important to harmonize outcome measures in future studies with topical agents in psoriasis to better appraise their efficacy.
