Alcohol hypersensitivity (AH), an exacerbation of respiratory symptoms in response to alcohol consumption, is common in aspirin-exacerbated respiratory disease and other forms of chronic rhinosinusitis (CRS). We speculated that these reactions relate to the activation of innate immune cells including basophils and, in particular, platelet-adherent basophils by polyphenolic compounds contained within eliciting alcoholic beverages. We investigated the absolute numbers of these cells in patients with AH and the ability of relevant polyphenolic compounds to cause cellular activation. Data were collected from 412 consecutive adults presenting to a tertiary care sinonasal clinic in whom the presence of AH was elicited. The CRS phenotype was determined and results from complete blood cell count and differential were analyzed. A subset of patients was invited to donate blood samples that were used to explore the ability of relevant compounds associated with alcohol consumption to activate platelet-nonadherent and platelet-adherent basophils. Activation was quantified by flow cytometry as up-regulated expression of CD63 and as secretion of lipid metabolites. Of the 412 patients enrolled, 69 (16.7%) endorsed having AH. Significantly higher platelet counts were seen in patients reporting AH. Red wine extract and several polyphenolic compounds produced basophil activation and this was primarily observed among platelet-adherent basophils. Platelet activation was further established as the release of thromboxane B2. The presence of AH is associated with significantly higher platelet levels and compounds present in alcoholic beverages can directly mediate both their activation and the activation of platelet-adherent basophils.
