A case report of recurrent anaphylaxis in a 36-year-old female:Lipid transfer protein syndrome

Lipid transfer protein (LTP) is a widely cross-reacting allergen in vegetables, fruits, nuts, or cereals. The amino acids sequence of LTP shows high structural similarity in various foods and thus acts as a pan-allergen. LTP syndrome is a new term for the pattern of clinical symptoms and natural course of allergy caused by LTP antigens. It is frequently reported by peaches mainly in the Mediterranean region, and reports in East Asia are rare. Therefore, this case report introduces a 36-year-old female Asian who experienced recurrent anaphylaxis and oral allergy syndrome, and finally diagnosed with LTP syndrome.
