Comparing four immunosuppressive agents for chronic spontaneous urticaria-A network meta-analysis

Area of Science:

• Immunology
• Dermatology
• Pharmacology

Background:

• Immunosuppression is crucial for chronic spontaneous urticaria (CSU) treatment.
• Limited literature exists on the comparative efficacy of multiple immunosuppressive agents for CSU.

Purpose of the Study:

• To compare the efficacy and safety of four immunosuppressive drugs (tripterygium glycosides, methotrexate, cyclosporine A, azathioprine) combined with antihistamines for CSU.
• To provide evidence-based medicine for CSU treatment.

Main Methods:

• Systematic literature search of RCTs and cohort studies from multiple databases (PubMed, Cochrane Library, EMBASE, etc.).
• Primary outcomes included weekly urticaria activity score 7 (UAS7) and adverse effects.
• Meta-analysis of pooled data from seven RCTs involving 410 participants.

Main Results:

• Cyclosporine A and tripterygium glycosides showed significant improvements in UAS7 scores when combined with antihistamines.
• Methotrexate and azathioprine also demonstrated potential benefits, though with varying effect sizes.
• No significant differences in side effects were observed among the studied immunosuppressive agents in the limited trials.

Conclusions:

• Cyclosporine A combined with antihistamines significantly improved UAS7 scores in CSU patients.
• Tripterygium glycosides are also effective in treating CSU.
• Further investigation into the comparative efficacy and safety of immunosuppressive agents in CSU is warranted.
