For decades, the approach to clinical care has involved assessment of a fairly small set patients' signs and symptoms, sampled over short period time with limited attention given individual variations in aetiology pathophysiology. Subsequently, therapy is assigned predominantly "one shoe fits all" approach. Precision medicine approaches are now starting change ways test, treat develop new thera...

relationship to proportion of regulatory T cells. Methods: Forty-five patients with history of systemic symptoms of allergy to Hymenoptera venom were included. Basophil reactivity before the treatment and after one year of allergen immunotherapy (AIT) was measured by CD63 expression, CD203c marker used for basophil identification. Cells were stimulated by aqueous solution of allergen in concent...

Dear Editor, both the paper by Pereira Santos et al and the Editorial on the latest issue of this Journal, stressed on the essential, fairly irreplaceable role of basophil activation test (BAT) in allergy diagnosis (1,2). Certainly, BAT is a cell-based test and in this sense it should give fundamental insights about the role of these circulating leukocytes in hypersensitivity reactions, chronic...

BACKGROUND Sensitization to hazelnut (HN) is frequent and requires clarification to determine whether this sensitization is clinically relevant. The aim of this study was to investigate basophil activation profiles in HN-sensitized and allergic subjects. METHODS Basophil activation was determined by flow cytometric analyses of CD63 and CD203c expression using several HN allergen concentration...

The basophil activation test (BAT) has been suggested as a complementary method for diagnosing drug allergies. The aim of this study was to evaluate the clinical utility of this test in patients with drug-induced anaphylaxis. In total, 19 patients, all of whom had a history of moderate to severe anaphylaxis, were enrolled. None of the causative drugs had available in vitro tests or reliable ski...

Background Local allergic rhinitis (LAR) is characterized by negative skin testing and serum specific IgE. Diagnosis is based on nasal provocation test (NPT), very sensitive but time-consuming, and/or presence of local synthesis of specific IgE (sIgE) which shows low sensitivity (22%). The aim of the study was to evaluate the presence of specific D. pteronyssinus (DP) activation of basophils by...
