Clinical Relevance

IgE-mediated reactions

IgE antibodies to spiny lobster have been measured in both atopic and non-atopic patients

When searching for possible shared antigens in assessing crustacea sensitivity, IgE antibodies to spiny lobster were measured in both atopic and non-atopic patients (1). In a study of adult shrimp-hypersensitive patients, a common major allergen of 36kd was identified in shrimp (f24), crayfish, crab (f23), and spiny lobster, which may explain the clinical histories of patients with immediate hypersensitivity reactions to the crustacea family (2).

Molecular Aspects

Cross-reactivity

Langust has a major allergen of 36 kD in common with shrimp (f24), crayfish (Rf320) and crab (f23).Crossreactivity with other Crustaceans can also be expected.(2)
