Unpredicted adverse reaction to omalizumab
Despite promising reports of the use of omalizumab as add-on therapy in patients with systemic mastocytosis and recurrent anaphylaxis during specific venom immunotherapy (VIT), unpredicted adverse effects may lead to therapy failure. We present the case of a patient with systemic mastocytosis and Hymenoptera venom allergy who was administered omalizumab as add-on therapy to improve VIT tolerability after repeated severe adverse reactions despite H1/H2-antihistamine prophylaxis. We describe an unexpected discontinuation of omalizumab following successful initiation of VIT in a patient with systemic mastocytosis, with subsequent lack of tolerability of VIT. An interesting aspect of this case is the correlation of basophil activation test results with both clinical tolerability and VIT intolerance

Robust expression of CCR3 as a single basophil selection marker in flow cytometry
Basophil activation tests (BAT) rely on different combinations of basophil selection and activation markers. Whereas activation markers, especially CD63, are widely validated, the most suitable and robust marker for basophil selection is still a matter of debate
Continuous apple consumption induces oral tolerance in birch-pollen-associated apple allergy
Patients with birch pollen allergy (major allergen: Bet v 1) have often an associated oral allergy syndrome (OAS) to apple, which contains the cross-reactive allergen Mal d 1. As successful birch pollen immunotherapy does not consistently improve apple related OAS symptoms, we evaluated whether regular apple consumption has an effect on OAS and immune parameters of Mal d 1 or Bet v 1 allergy
