ABSTRACT
Background: Component-resolved diagnosis plays a key role in the diagnosis and treatment of honeybee venom allergy (HVA). Our aimwas to study whether any of the allergens not included in the usual diagnostic platforms are relevant in our population.Patients and Methods: The allergenic sensitization profile of Spanish patients who experienced a systemic reaction after a honeybee stingand were diagnosed with HVA was studied by immunoblotting based on raw autochthonous Apis mellifera venom characterized usingSDS-PAGE and mass spectrometry and a commercial assay (ImmunoCAP).Results: Allergens in the International Union of Immunological Societies database were detected in the raw A mellifera venom extract used,except Api m 12. Sera from 51 patients with a median (IQR) age of 46.2 years (35.6-54.6) were analyzed. ImmunoCAP revealed Api m 1and Api m 10 to be major allergens (88.2% and 74.5%, respectively). Moreover, Api m 6 (85.4%) was detected by immunoblotting.Conclusion: Api m 1, Api m 6, and Api m 10 are major A mellifera venom allergens in our population (AU)
RESUMEN
Antecedentes: El diagnóstico molecular puede ser una herramienta valiosa en el diagnóstico y el tratamiento de la alergia al veneno deabeja. Este estudio investiga si alguno de los alérgenos no incluidos en las plataformas diagnósticas habituales son relevantes en nuestrapoblación.Pacientes y métodos: Estudiamos mediante immunoblotting el perfil de sensibilización alergénica en pacientes españoles diagnosticadosde alergia al veneno de abeja. Los resultados se compararon con los obtenidos usando un ensayo comercial (ImmunoCAP). El venenocrudo de Apis mellifera autóctona se obtuvo y caracterizó mediante SDS-PAGE y espectrometría de masas.Resultados: Los alérgenos descritos en la base de datos International Union of Immunological Societies (IUIS) fueron detectados enel extracto crudo de veneno de A. mellifera utilizado. Se analizaron sueros de 51 pacientes con una edad media de 46,2 años (rangointercuartil 35,6–54,6). Api m 1 y Api m 10 fueron detectados como alérgenos mayoritarios (88,2% y 74,5%, respectivamente) usandoImmunoCAP. Además, se encontró Api m 6 (85,4%) mediante immunoblotting.Conclusión: Nuestra población reconoce Api m 1, Api m 6 y Api m 10 como alérgenos mayoritarios del veneno de A. mellifera (AU)
