BACKGROUND Hypersensitivity to raw fruits and vegetables is often associated with respiratory allergy to birch (Betula verrucosa) pollen and is considered to be the most prevalent form of food allergy in adults sensitized to birch pollen. OBJECTIVE The aim of the study was to investigate the association of clinical allergy and IgE profiles in individuals(More)
Mosquito bites usually cause wealing and delayed bite papules. Cetirizine decreases wealing, bite papules and pruritus but the effect of other antihistamines on mosquito bites is unknown. We studied the effect of ebastine in 30 mosquito bite-sensitive adult subjects. Ebastine 10 mg or 20 mg and placebo were given for 4 days in a cross-over fashion. Aedes(More)
BACKGROUND Respiratory allergy to environmental molds is relatively common, and fungal allergen-specific reactivity seems to cluster in certain persons. However, generalized reactions caused by ingested fungi have seldom been described. OBJECTIVE To describe a mold-sensitized patient who developed multiple anaphylactic reactions after ingesting a yeast(More)
BACKGROUND Occupational contact urticaria (CU) from plants is often reported, but it is less often attributed to decorative houseplants. We present an atopic gardener and caretaker of plants who developed CU when occupationally exposed to weeping fig, spathe flower, and yucca. METHODS Sensitization was evaluated by skin prick tests (SPT) and analyses for(More)
BACKGROUND Within a large prospective study, the Global Asthma and Allergy European Network (GA(2) LEN) has collected skin prick test (SPT) data throughout Europe to make recommendations for SPT in clinical settings. OBJECTIVE To improve clinical interpretation of SPT results for inhalant allergens by providing quantitative decision points. METHODS The(More)
Wealing and pruritic, long-lasting papules are a common nuisance from mosquito bites. Antihistamines can be expected to decrease wealing, but their effect on the delayed bite symptoms needs to be elucidated. We studied the effect of ebastine in 28 mosquito-bite sensitive adult subjects exposed to Aedes communis bites in the field. Ebastine 20 mg and placebo(More)
People frequently experience whealing and delayed papules from mosquito bites. Various antihistamines have previously been tried for the treatment of this condition. We performed a double-blind, placebo-controlled, cross-over study with levocetirizine 5 mg and matched placebo in 30 adults who were sensitive to mosquito bites. On the third treatment day the(More)
BACKGROUND People frequently experience whealing and delayed papules from mosquito bites. Whealing is mediated by antisaliva immunoglobulin (Ig)E antibodies and histamine. Cetirizine, ebastine and loratadine have earlier shown effects on mosquito-bite reactions but no comparative studies exist. METHODS A double-blind, placebo-controlled, cross-over study(More)
BACKGROUND Children frequently experience harmful whealing and delayed papules from mosquito bites. Whealing is mediated by antisaliva IgE antibodies and histamine, but the effect of antihistamines on mosquito-bite symptoms has not been evaluated in children. METHODS The effect of loratadine (0.3 mg/kg) was examined in 28 mosquito-bite-sensitive children(More)
