Due to issues such as cross\u2010reactivity, diagnosis of shrimp allergy is still inaccurate, requiring the need for double\u2010blind, placebo\u2010controlled food challenges (<jats:styled-content style=\"fixed-case\">DBPCFC<\/jats:styled-content>). A better understanding of the relationship between laboratory findings and clinical reactivity is needed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To determine whether sensitization to certain shrimp allergens or recognition of particular IgE epitopes of those allergens are good biomarkers of clinical reactivity to shrimp.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirty\u2010seven consecutive patients were selected with clinical histories of shrimp allergy. Skin prick test, specific IgE determinations, <jats:styled-content style=\"fixed-case\">DBPCFC<\/jats:styled-content> and immunoblot assays to shrimp extract were performed.

By microarray, patients with positive challenges showed more intense binding to shrimp peptides than those with negative challenges. Statistically significant differences in terms of the frequency and intensity of IgE binding to some epitopes were observed between the two groups. Diagnostic efficiency was higher for individual epitopes than for proteins. Particularly, efficiency was highest for certain Lit v 1 and Lit v 2 epitopes, followed by Lit v 3 and Lit v 4 epitopes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion and Clinical Relevance<\/jats:title><jats:p>Patients with positive shrimp challenges present in general more intense and diverse epitope recognition to all four shrimp allergens. IgE antibodies to these shrimp epitopes could be used as biomarkers for prediction of clinical reactivity in subjects with sensitization to shrimp. Patients with positive shrimp challenges show more intense sensitization and more diverse epitope recognition. Several IgE\u2010binding shrimp epitopes could be used as biomarkers for predicting clinical reactivity in subjects with sensitization to shrimp.<\/jats:p><\/jats:sec>","DOI":"10.1111\/j.1365-2222.2011.03920.x","type":"journal-article","created":{"date-parts":[[2011,12,22]],"date-time":"2011-12-22T20:08:05Z","timestamp":1324584485000},"page":"293-304","source":"Crossref","is-referenced-by-count":71,"title":["Is epitope recognition of shrimp allergens useful to predict clinical reactivity?"],"prefix":"10.1111","volume":"42","author":[{"given":"R.","family":"Ayuso","sequence":"first","affiliation":[{"name":"Division of Allergy &amp; Immunology and The Jaffe Food Allergy Research Institute Mount Sinai School of Medicine New York NY USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"S\u00e1nchez\u2010Garcia","sequence":"additional","affiliation":[{"name":"Division of Allergy &amp; Immunology and The Jaffe Food Allergy Research Institute Mount Sinai School of Medicine New York NY USA"},{"name":"Allergy Section Hospital Infantil Universitario del Ni\u00f1o Jes\u00fas Madrid Spain"},{"name":"Section of Allergy Fundaci\u00f3n Jimenez D\u00edaz Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Pascal","sequence":"additional","affiliation":[{"name":"Division of Allergy &amp; Immunology and The Jaffe Food Allergy Research Institute Mount Sinai School of Medicine New York NY USA"},{"name":"Department of Immunology Allergy Unit Centre de Diagn\u00f2stic Biom\u00e8dic (CDB) Hospital Cl\u00ednic, Institut d'Investigacions Biom\u00e8diques August Pi i Sunyer (IDIBAPS) Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Lin","sequence":"additional","affiliation":[{"name":"Division of Allergy &amp; Immunology and The Jaffe Food Allergy Research Institute Mount Sinai School of Medicine New York NY USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Grishina","sequence":"additional","affiliation":[{"name":"Division of Allergy &amp; Immunology and The Jaffe Food Allergy Research Institute Mount Sinai School of Medicine New York NY USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Z.","family":"Fu","sequence":"additional","affiliation":[{"name":"Division of Allergy &amp; Immunology and The Jaffe Food Allergy Research Institute Mount Sinai School of Medicine New York NY USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
