Oral allergy syndrome to chicory associated with birch pollen allergy

BACKGROUND: A few cases of IgE-mediated chicory allergy with oral, cutaneous, and/or respiratory symptoms are reported. We present 4 patients with inhalant birch pollen allergy and oral allergy syndrome to chicory. IgE-binding proteins in chicory and cross-reactivity with birch pollen were studied. METHODS: Chicory extract was prepared and immunoblotting was used to study IgE reactivity and cross-reactions with birch pollen. RESULTS: The pattern of IgE binding to chicory was variable among the patients, with protein bands recognized at 18, 21, 40, 52 and 71 kD. Bet v 1-like proteins were detected in chicory by monoclonal antibody binding. Chicory-birch pollen cross-reactivity, as studied in 2 patients from whom enough serum was available, could be demonstrated but did not involve the Bet v 1 protein family. In one of these cases, a 51-kD protein of birch pollen was found to be responsible for cross-reactivity. CONCLUSIONS: Chicory should be added to the list of foods that can cross-react with birch pollen and cause the birch pollen-associated oral allergy syndrom

The Welfare Agenda of the Populist Radical Right in Western Europe: Combining Welfare Chauvinism, Producerism and Populism*

Recent scholarship on the populist radical right tends to imprecisely describe the welfare agenda of this party family with reference to its key ideological characteristics of nativism, authoritarianism, and populism. We propose an alternative analytical framework that considers the multidimensionality of welfare state positions and the “deservingness criteria” that underlie ideas about welfare entitlement. Applying this framework to a sample of four European populist radical right parties, we conclude that three interrelated frames inform their welfare agenda. These parties, we argue, advocate social closure not only on the basis of the deservingness criterion of identity (welfare chauvinism), but also on criteria of control, attitude, and reciprocity (welfare producerism) and on an antagonism between the people and the establishment (welfare populism). Understanding the welfare agenda of the populist radical right requires us to move beyond welfare chauvinism and to reconsider the concept of welfare producerism and its interaction with welfare chauvinism
