Efficacy and Safety of Mucopolysaccharide Polysulfate Cream for Non-Exudative Eczema: A Systematic Review and Meta-Analysis.

Abstract

Background: Mucopolysaccharide polysulfate (MPS) cream as a moisturizer is widely applied to treat eczema, and a lot of clinical trials have demonstrated its efficacy and safety. However, there is no further research to collect and analyze these studies. Objective: This meta-analysis aimed to assess the efficacy and safety of MPS cream as monotherapy or add-on therapy for non-exudative eczema. Methods: Ten databases were searched to identify the eligible randomized controlled trials (RCTs) from their inception to July 31, 2021. Revman 5.3 software was used for the meta-analysis. Results: A total of eligible 20 studies were included. Among the 20 studies, 2 studies compared MPS cream with other moisturizers, 14 compared MPS cream plus topical corticosteroids (TCS) with TCS alone, and 4 compared with MPS cream plus tacrolimus ointment with tacrolimus ointment alone. The pooled results demonstrated that MPS cream had a higher total efficacy rate [Risk ratio (RR) 1.21, 95% CI: 1.12 to 1.30, P < 0.00001], a lower recurrence rate (RR 0.44, 95% CI: 0.26 to 0.74, P = 0.002) and a lower pruritus score [mean difference (MD) -1.78, 95% CI: -2.16 to -1.40, P < 0.00001] than urea cream or vaseline ointment. Moreover, in comparison with TCS or tacrolimus ointment alone, the combination treatment performed better in terms of total efficacy rate, total symptom score, recurrence rate, and pruritus score. For safety, the skin adverse events were mild, and MPS cream as monotherapy or add-on therapy did not increase the risk of skin adverse events. Conclusions: MPS cream as monotherapy or add-on therapy could provide a good effect for treating non-exudative eczema with mild and tolerable skin adverse events. However, due to the suboptimal quality of the included studies, high-quality and large-sample RCTs are needed in the future for update or validation.
