BACKGROUND: Wasp venom is a complex mixture containing proteins, enzymes and small molecules, including some of the most dangerous allergens. The greater banded wasp (Vespa tropica) is well-known for its lethal venom, whose one of the major components is a hyaluronidase (HAase). It is believed that the high protein proportion and activity of this enzyme is responsible for the venom potency. METHODS: In the present study, cDNA cloning, sequencing and 3D-structure of Vespa tropica venom HAase were described...

BACKGROUND: Hymenoptera stings can cause severe anaphylaxis in untreated venom-allergic patients. A correct diagnosis regarding the relevant species for immunotherapy is often hampered by clinically irrelevant cross-reactivity. In vespid venom allergy, cross-reactivity between venoms of different species can be a diagnostic challenge. To address immunological IgE cross-reactivity on molecular level, seven recombinant antigens 5 of the most important Vespoidea groups were assessed by different diagnostic setups...

The main insects causing allergy reactions to stinging insect in humans are Apidae (bees), Vespidae (wasps, yellow jackets and hornets) and Formicidae (ants). Their venom stings are composed of various biologically active peptides and protein components, some of which can cause toxicity or anaphylaxis in humans. The protein venom demonstrate some common allergenic activity such as for fire ants and vespids, which have two common allergens that are phospholipase A1 (enzymatic activity) and antigen 5 with unknown biological activity...

BACKGROUND: Many institutions recommend a stepwise approach to intradermal testing for venom allergy. This is costly and uncomfortable for the patient. The rationale for this approach is the risk of potential adverse reactions to testing with the maximal dose alone. OBJECTIVE: To evaluate the safety of a single-step approach to venom allergy testing. METHODS: The authors retrospectively reviewed the charts of 300 consecutive patients with suspected hymenoptera venom allergy based on history who underwent venom allergy testing in a single allergist's clinic where a single-step protocol had been adopted...

INTRODUCTION: Sensitization to the Hymenoptera venom is one of the main causes of anaphylaxis in Poland. Venom immunotherapy is the only effective treatment in such cases. Comprehensive patient care includes also education. The aim of our study was to assess the state of knowledge and to evaluate the quality of life and the anxiety level in patients allergic to the Hymenoptera venom after anaphylactic reaction. MATERIAL AND METHODS: The survey was carried out in the period of the insects flight in 61 adult subjects (35 wasp and 26 bee allergic), using a validated Vespid Allergy Quality of Life Questionnaire (VQLQ), Hospital Anxiety and Depression Scale, and subjective assessment of anxiety level...

Recombinant allergens improve the diagnostic precision in Hymenoptera venom allergy (HVA), in particular in patients with double sensitization to both honey bee (HBV) and yellow jacket venom (YJV). While currently available vespid allergens allow the detection of >95% of YJV-allergic patients, the sensitization frequency to the only available HBV marker allergen rApi m 1 in HBV-allergic patients is lower. Here, we demonstrate that sIgE to additional HBV marker allergens rApi m 3 and rApi m 10 allows the detection of genuine HBV sensitization in 46-65% of Api m 1 negative sera...

Experimental studies, epidemiological data, and clinical observations suggest that the gender factor is involved in the development and manifestation of IgE-dependent allergic diseases. We intend to answer the question if sex-related factors may play a role in Hymenoptera venom allergy (HVA). In the majority of recent studies the frequency of HVA symptoms with respect to both LL and SYS reactions is similar for men and women, while proven sensitization to insect venom is less frequent in women. Studies assessing clinical reactivity in HVA indicate that male sex and vespid venom allergy are factors increasing the risk of severe allergic reactions...

REVIEW

BACKGROUND: Stings by Hymenoptera (honey bees, vespids, ants) can cause systemic allergic reactions (SARs). Venom immunotherapy (VIT) is highly effective and reduces an allergic patient's risk of a recurrent SAR to less than 5-20%. The risk of a recurrent SAR to a re-sting decreases the longer VIT is continued. The recommended duration of VIT is at least 3 to 5 years. RISK FACTORS: Risk factors for recurrent SARs to a sting after stopping VIT have been identified and discussed: Recommendations concerning stopping VIT: For patients without any of the identified risk factors, VIT should be continued for 5 rather than 3 years...

AIM: The prevalence of systemic reactions (SR) to Hymenoptera stings in children was estimated in values lower than 1% in early studies but much higher in recent surveys. We evaluated the current prevalence and the incidence of SR and large local reactions (LLR) to Hymenoptera stings in children in Italy. METHODS: The data on children were collected from the database of the population study on the city of Cotignola, analyzing the answers to the part of the questionnaire about Hymenoptera stings, that concerned if the subject was ever stung by apids or vespids, if there has been a SR or a LLR, and if subjects with reactions received a diagnostic evaluation and a medical treatment...

PURPOSE OF REVIEW: Diagnosis of insect sting allergy and prediction of risk of sting anaphylaxis are often difficult because tests for venom-specific IgE antibodies have a limited positive predictive value and do not reliably predict the severity of sting reactions. RECENT FINDINGS: Component-resolved diagnosis using recombinant venom allergens has shown promise in improving the specificity of diagnostic testing for insect sting allergy. Basophil activation tests have been explored as more sensitive assays for identification of patients with insect allergy and for prediction of clinical outcomes...

Antigen-5 is one of the major allergens identified in wasp venoms, and despite the fact that its biological function is still unknown, many studies have demonstrated its allergenicity. In this study, the biochemical and structural characterization of antigen-5 from the venom of the social wasp Polybia paulista are reported. A gel-based mass spectrometry strategy with CID fragmentation methods and classical protocols of protein chemistry, which included N- and C-terminal sequencing, were used to assign the complete sequence and determine the presence/location of the post-translational modifications (PTMs) of this protein...

REVIEW
Leonard Bielory, Kevin Lyons, Robert Goldberg
Allergies are prevalent throughout the United States and impose a substantial quality of life and economic burden. The potential effect of climate change has an impact on allergic disorders through variability of aeroallergens, food allergens and insect-based allergic venoms. Data suggest allergies (ocular and nasal allergies, allergic asthma and sinusitis) have increased in the United States and that there are changes in allergies to stinging insect populations (vespids, apids and fire ants). The cause of this upward trend is unknown, but any climate change may induce augmentation of this trend; the subspecialty of allergy and immunology needs to be keenly aware of potential issues that are projected for the near and not so distant future...

BACKGROUND: Venom immunotherapy is highly efficacious in preventing anaphylactic sting reactions. However, there is an ongoing discussion regarding patient selection and whether and how to apply a cost-benefit analysis of venom immunotherapy. In order to help decision-making, we investigated the re-sting frequency of hymenoptera-venom-allergic patients to single out those at high risk. METHODS: In this retrospective study, re-sting data of 96 bee-venom-allergic patients and 95 vespid-venom-allergic patients living mainly in a rural area of Switzerland were analyzed...
