Key clinical point: Patients with atopic dermatitis (AD) have an increased risk of developing food allergy (FA), food sensitivity (FS), and challenge-proven food allergy (CPFA), and vice versa.
Major finding: AD was significantly associated with an increased risk for FS (pooled odds ratio [pOR] 4.17; 95% CI 3.03-5.75), FA (pOR 3.91; 95% CI 3.44-4.45), and CPFA (pOR 4.99; 95% CI 2.20-11.35). A significantly increased risk for AD was observed in individuals with FS (pOR 3.92; 95% CI,2.88-5.33), FA (pOR 4.06; 95% CI 3.54-4.65), and CPFA (pOR 4.93; 95% CI 2.74-8.84).
Study details: Findings are from a meta-analysis of 465 studies involving patients with AD (n = 225,568); reference individuals without AD (n = 1,128,322); individuals with FS, FA, and CPFA (n = 1,357,793); and reference individuals without FS, FA, and CPFA (n = 1,244,596).
Disclosures: This study did not receive any funding. Some authors declared serving as advisors, speakers, or consultants for or receiving speaking or consulting fees from various sources.
