Based on the knowledge of the living conditions and habitat of social Aculeatae a series of recommendations have been formulated which can potentially greatly minimize the risk of field re-sting. After a systemic sting reaction, patients should be referred to an allergy specialist for evaluation of their allergy, and if necessary venom immunotherapy (VIT).(More)
The purpose of diagnostic procedure is to classify a sting reaction by history, identify the underlying pathogenetic mechanism, and identify the offending insect. Diagnosis of Hymenoptera venom allergy thus forms the basis for the treatment. In the central and northern Europe vespid (mainly Vespula spp.) and honeybee stings are the most prevalent, whereas(More)
BACKGROUND Severe anaphylaxis to honeybee or vespid stings is associated with a variety of risk factors, which are poorly defined. OBJECTIVE Our aim was to evaluate the association of baseline serum tryptase concentrations and other variables routinely recorded during patient evaluation with the frequency of past severe anaphylaxis after a field sting.

PURPOSE OF REVIEW Epidemiology and especially the natural history of Hymenoptera allergy form the background that is essential to improving the clinical management of insect venom allergic patients. This review focuses on the emergence of recent data which could help provide further enlightenment in this field. RECENT FINDINGS The latest data on the(More)
Hymenoptera stings can cause severe systemic allergic reactions and occasionally fatal anaphylaxis, which contribute significantly to morbidity and deterioration in health-related quality of life. The latest epidemiological data confirm the importance of insect sting allergy as a cause of anaphylaxis. Despite the high prevalence of asymptomatic(More)
BACKGROUND Severe side effects during venom immunotherapy (VIT) are associated with a variety of risk factors. OBJECTIVE Our aim was to evaluate the association of baseline serum tryptase concentration (BTC) and of other parameters, which are routinely recorded during patient evaluation, with the frequency of severe reactions requiring an emergency(More)
Sera of 17 patients receiving immunotherapy for house-dust mite allergy were tested for IgE antibodies against snail and shrimp. Serum samples were taken at the start of immunotherapy and 14-20 months later. While the average IgE response to mite, Der p 1, and Der p 2 did not alter significantly, the average response to snail showed a significant increase.(More)
PURPOSE OF REVIEW Knowledge of the epidemiology, natural history and risk factors of insect-venom allergy is crucial for improving the clinical management of allergic patients. This review focuses on the recent research on these aspects of Hymenoptera-sting anaphylactic reactions. RECENT FINDINGS The latest data from population-based studies of(More)
OBJECTIVES To evaluate the performances of an allergen microarray in multi-sensitized allergic patients with respiratory symptoms. DESIGN AND METHODS 321 patients and 92 controls were included in this study. Specific serum IgE were assayed using ImmunoCAP ISAC, a microarray containing 103 components derived from 47 allergens and results were compared with(More)
