Over the past decades, red meat allergy, also known as mammalian meat allergy, which manifests differently from classic food allergies, has been reported in different countries and regions, including China. The allergen of this disease is not a protein but an oligosaccharide: galactose‐α‐1,3‐galactose, i.e., alpha‐gal or α‐gal. Therefore, this clinical syndrome is also called α‐gal syndrome (AGS). It clinically manifests as delayed anaphylaxis, i.e., patients generally develop allergic symptoms 2–6 h after ingesting red meat. This clinical manifestation is believed to be related to sensitization to α‐gal after tick bites. Sensitized individuals may also develop anaphylaxis after ingesting food and medicine or being exposed to medical equipment containing α‐gal, such as cetuximab and gelatin. Here, the literature on AGS is reviewed for a better understanding of its pathogenesis, clinical diagnosis, and treatment. [ABSTRACT FROM AUTHOR] |
