Effectiveness and Safety of the Combination of the Traditional Chinese Medicine Prescription Jade Screen and Desloratadine in the Treatment of Chronic Urticaria: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective: The aim of this study is to systematically evaluate the clinical efficacy and safety of the traditional Chinese medicine prescription Jade Screen combined with desloratadine in the treatment of chronic urticaria.

Methods: Two researchers independently conducted literature searches. The extracted data were analyzed using Rev Man 5.2.3 software. The established retrieval time range of the various databases was up to 15 March, 2017.

Results: Sixteen randomized controlled trials were included in this study. The results of the meta-analysis showed that the total effective rate of using Jade Screen and desloratadine in combination to treat chronic urticaria was higher than that with desloratadine alone ( < 0.00001), while its recurrence rate ( < 0.00001) and symptom score ( = 0.006) were both significantly lower than the latter. The rate of adverse reaction in the combination group was lower than that when orally taking desloratadine alone ( = 0.74), and the serum level of total IgE in the combination group was lower than that when orally taking desloratadine alone ( = 0.82); however, the results of the rate of adverse reaction and the serum level of total IgE were insignificant.

Conclusion: Using Jade Screen and desloratadine together to treat chronic urticaria gains a better clinical effect than using desloratadine alone.
