Fundamentos: Os alergénios envolvidos na alergia alimentar exacerbada por cofator (CEFA) variam geogra‑ ficamente; no Sul da Europa, as Lipid transfer proteins (LTP) têm maior relevância e Ásia a ómega-5-gliadina (ω5G). As características clinicas parecem diferir consoante o alergénio envolvido. Objetivos: Comparação caracte‑ rização dos doentes com CEFA LTP (CEFA-LTP) e/ou ω5G (CEFA- ω5G). Métodos: Estudo observacional re‑ trospetivo CEFA-LTP ω5G, entre 01/2012 12/2020. Análise demográfica,...
