Background:
Short courses of adjunctive systemic corticosteroids are commonly used to treat acute urticaria and chronic urticaria flares (both with and without mast cell-mediated angioedema), but their benefits and harms are unclear.
Objective:
To evaluate the efficacy and safety of treating acute urticaria or chronic urticaria flares with versus without systemic corticosteroids.
Methods:
We searched the MEDLINE, EMBASE, CENTRAL, CNKI, VIP, Wanfang, and CBM databases from inception to July 8, 2023, for randomized controlled trials of treating urticaria with versus without systemic corticosteroids. Paired reviewers independently screened records, extracted data, and appraised risk of bias with the Cochrane 2.0 tool. We performed random-effects meta-analyses of urticaria activity, itch severity, and adverse events. We assessed certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluations (GRADE) approach.
Results:
We identified 12 randomized trials enrolling 944 patients. For patients with low or moderate probability (17.5%-64%) to improve with antihistamines alone, add-on systemic corticosteroids likely improve urticaria activity by a 14% to 15% absolute difference (odds ratio [OR], 2.17, 95% confidence interval [CI]: 1.43-3.31; number needed to treat [NNT], 7; moderate certainty). Among patients with a high chance (95.8%) for urticaria to improve with antihistamines alone, add-on systemic corticosteroids likely improved urticaria activity by a 2.2% absolute difference (NNT, 45; moderate certainty). Corticosteroids may improve itch severity (OR, 2.44; 95% CI: 0.87-6.83; risk difference, 9%; NNT, 11; low certainty). Systemic corticosteroids also likely increase adverse events (OR, 2.76; 95% CI: 1.00-7.62; risk difference, 15%; number needed to harm, 9; moderate certainty).
Conclusions:
Systemic corticosteroids for acute urticaria or chronic urticaria exacerbations likely improve urticaria, depending on antihistamine responsiveness, but also likely increase adverse effects in approximately 15% more.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
