Corticosteroids for the common cold.

Area of Science:

• Respiratory Medicine
• Pharmacology

Background:

• The common cold is a prevalent illness causing significant healthcare consultations and lost productivity.
• Current treatments for the common cold offer limited symptomatic relief.
• Corticosteroids, known for their anti-inflammatory properties, are effective in other upper respiratory infections and may benefit the common cold.

Purpose of the Study:

• To evaluate the efficacy of corticosteroids compared to usual care for the common cold in pediatric and adult populations.
• To assess the clinical response rates in patients treated with corticosteroids for common cold symptoms.

Main Methods:

• Systematic review of randomized, double-blind, controlled trials comparing corticosteroids to placebo or standard care.
• Searched multiple databases including CENTRAL, DARE, MEDLINE, and EMBASE for relevant studies.
• Data extraction and quality assessment were performed independently by two reviewers; meta-analysis was not possible, necessitating a narrative synthesis of findings.

Main Results:

• Two trials with 253 participants were included, both using intranasal corticosteroids versus placebo; no oral corticosteroid trials were found.
• Intranasal corticosteroids showed no significant benefit in reducing the duration or severity of common cold symptoms.
• No differences were observed in adverse events, complications, viral presence, or secondary infection rates between groups.

Conclusions:

• Existing evidence does not support the use of intranasal corticosteroids for symptomatic relief of the common cold.
• The current evidence base is limited by the small number of trials and participants, suggesting a need for further investigation.
• Larger, randomized, placebo-controlled trials in both adults and children are recommended to definitively answer the question of corticosteroid efficacy for the common cold.
