Abstract Background: Denatonium benzoate (DB), one of the bitterest compounds known to man, is currently added to a wide range of products and is also used for alcohol denaturation. Some reports demonstrated that asthmatic symptoms are associated with DB exposure but the possible links between DB and IgE-mediated allergy susceptibility have not been examined to date. We investigated the effects of DB on IgE-mediated mast cell degranulation in vitro and in the ovalbumin (OVA)-induced mouse model of allergy.Methods: DB treatments were given to RBL-2H3 IgE-sensitized rat mast cell/basophil cells and KU812 human basophilic cells together with OVA-induced allergic BALB/c mice. Allergic mediator release, Ca2+ influx and OVA-specific IgE anaphylactic shock symptoms were measured along with the cell-surface expression of the α-subunit of high-affinity IgE receptor FcεRI on mast cells.Results: DB increases β-hexosaminidase (β-hex) release and Ca2+ mobilization in IgE-mediated activated RBL-2H3 and KU812 cells, and enhanced the cell-surface expression of FcεRIα. DB also promoted the severity of OVA-induced anaphylactic and diarrheic symptoms which was accompanied by mucus thickness in jejunum and the levels of β-hex, histamine and OVA-specific IgE in allergy mice, as well as the levels of FcεRIα mRNA and the FcεRIα proteinin isolated mucosal mast cells. Conclusions: DB treatments can promote the IgE-mediated mast cell degranulation in vitro and OVA-induced allergic susceptibility in mice by upregulating mast-cell-surface FcεR1α expression, providing evidence for DB exposure in promoting allergy susceptibility.

Cutaneous manifestations are uncommon with malaria. These include urticaria, purpura fulminans, and petechial rash. We report on a series of three patients from a single family who had an urticarial rash with fever that was subsequently diagnosed to be caused by malaria. Urticarial rash has been previously reported with both falciparum and vivax malaria infections. Although the exact pathogenesis is not clear urticarial rash might be related with IgE mediated mast cell degranulation.
