BACKGROUND: An omalizumab treatment and a high maintenance venom dose may both help to prevent recurrent systemic allergic reactions (SAR) to venom immunotherapy (VIT). The effectiveness of this combination therapy, however, is unclear. OBJECTIVE: We wanted to explore the possibility whether a temporary treatment with the anti-IgE antibody omalizumab, combined with a VIT using an elevated maintenance dose of >100 μg venom may establish a permanent tolerance of maintenance VIT...

PURPOSE OF REVIEW: This review aims to update the world status of the main allergenic stinging Hymenoptera. RECENT FINDINGS: In this review, we consider the problems that social Hymenoptera (bees, wasps and ants) could represent in the nearest future for human health in different parts of the world. SUMMARY: Distribution and consistency of allergenic species including venomous insects are interested by accelerated dynamics caused by climate changes and globalization...

REVIEW
Laurent L Reber, Joseph D Hernandez, Stephen J Galli
Anaphylaxis is a severe systemic hypersensitivity reaction that is rapid in onset; characterized by life-threatening airway, breathing, and/or circulatory problems; and usually associated with skin and mucosal changes. Because it can be triggered in some persons by minute amounts of antigen (eg, certain foods or single insect stings), anaphylaxis can be considered the most aberrant example of an imbalance between the cost and benefit of an immune response. This review will describe current understanding of the immunopathogenesis and pathophysiology of anaphylaxis, focusing on the roles of IgE and IgG antibodies, immune effector cells, and mediators thought to contribute to examples of the disorder...

The stinging hymenopteran velvet ants (Mutillidae) and bumble bees (Apidae: Bombus spp.) have both undergone extensive diversification in aposematic color patterns, including yellow-red hues and contrasting dark-light body coloration, as a result of Müllerian mimicry. Understanding the genetic and developmental mechanisms underlying shifts in these mimetic colors requires characterization of their pigmentation. In this study, a combination of solubility, spectrophotometry, and melanin degradation analysis are applied to several color forms and species of these lineages to determine that orange-red colors in both lineages are comprised of primarily dopamine-derived pheomelanins...

OBJECTIVES: To discuss medications that cause anaphylaxis in older adults and its treatment, with a focus on epinephrine. DATA SOURCE: A search of PubMed using the terms "anaphylaxis," "drug-induced anaphylaxis," "epinephrine autoinjectable," "anaphylaxis diagnosis," "anaphylaxis treatment," and "epinephrine cost" was performed. English-language articles from January 2000 to August 2016 appearing in these searches were reviewed. STUDY SELECTION/DATA EXTRACTION: Relevant review articles, consensus statements, practice parameters, task force recommendations, and original articles were assessed for recognition and treatment of drug-induced anaphylaxis...

BACKGROUND: Venom immunotherapy (VIT) is highly effective in preventing allergic reactions to insect stings, but the appropriate venom must be used to achieve clinical protection. In patients with multiple positive results to venoms, molecular allergy diagnostics or CAP-inhibition may identify the causative venom. Concerning allergy to venom from Polistes spp. it has been proposed that only the European species P. dominulus should be used for VIT. However, this recommendation is not present in any international guideline...

The current loss of biodiversity has found its way into the media. Especially the loss of bees as pollinators has recently received much attention aiming to increase public awareness about the consequence of pollinator loss and strategies for protection. However, pollinating insects like bees often prompt considerable anxiety. Negative emotions such as fear and disgust often lead to lack of support for conservation and appropriate initiatives for protection. Our study monitored perceptions of bees in the contexts of conservation and danger bees possibly represent by applying a semantic differential using contrasting adjectives under the heading "I think bees are…"...

Various ocular and systemic reactions have been associated with insect sting. However, insect stings have been rarely reported to cause exotropia and diplopia. We encountered exotropia in a 6-year-old child with rhabdomyolysis of the left lower extremities caused by an insect sting. Exotropia and diplopia developed within 1 day after the sting and improved completely 1 week after the onset of symptoms. Clinicians should be aware of the potential for the development of exotropia in patients with insect stings, which requires careful follow-up...

OBJECTIVE: The purpose of this study was to evaluate the clinical characteristics of allergy to stings from the Hymenoptera order of insects in a hospital in Thailand. METHODS: A descriptive retrospective analytical study was carried out in inpatients and outpatients suffering from Hymenoptera stings from 2009 to 2013 in Siriraj Hospital. RESULTS: Medical records of 386 patients with an allergy to Hymenoptera stings were evaluated. Anaphylaxis was more common in patients younger than 15 years, who comprised 22...

The application of insect and arthropod information to medicolegal death investigations is one of the more exacting applications of entomology. Historically limited to homicide investigations, the integration of full time forensic entomology services to the medical examiner's office in Harris County has opened up the opportunity to apply entomology to a wide variety of manner of death classifications and types of scenes to make observations on a number of different geographical and species-level trends in Harris County, Texas, USA...

We experimentally studied the predatory behavior of Polybia rejecta (Vespidae, Polistinae, Epiponini) towards 2-88 mm-long insects attracted to a UV light trap. Foragers, which began to hunt at 6:30, selected 4-14 mm-long prey insects. Prey detection by sight by hovering wasps was confirmed using decoys. After the wasps landed and walked along a sinuous path, prey were detected by contact or from a distance (1-3cm). This was followed by seizure, stinging (contrarily to most other known cases), prey manipulation and retrieval...

Hymenopterans - one of the 'big four' of insect orders - includes the sawflies, wasps, ants and bees. Two phylogenomic studies now resolve hymenopteran phylogeny and provide scenarios for the evolution of major lineages and key lifestyle transitions.

Anaphylaxis is defined as a serious allergic or hypersensitivity reaction in the most cases as a result of an IgE-mediated allergic reaction that is rapid in onset and may cause death. Common triggers are foods, insect stings, and medications. The medical treatment includes, epinephrine, glucocorticoids, antihistamines and inhaled bronchodilators, with the aim to prevent progression to life-threatening respiratory and/or cardiovascular symptoms.

Polybia paulista (Hymenoptera: Vespidae) is a neotropical social wasp from southeast Brazil. As most social Hymenoptera, venom from P. paulista comprises a complex mixture of bioactive toxins ranging from low molecular weight compounds to peptides and proteins. Several efforts have been made to elucidate the molecular composition of the P. paulista venom. Data derived from proteomic, peptidomic and allergomic analyses has enhanced our understanding of the whole envenoming process caused by the insect sting...

BACKGROUND: The Michigan Legislature mandated that all public schools stock epinephrine auto-injectors (EAIs). A minimal amount is known regarding the incremental value of EAIs in schools. Our primary objective was to describe the frequency of administration of epinephrine for EMS patients with acute allergic reactions in public schools. Our secondary objective was to estimate the cost of mandating public schools to stock EAIs. METHODS: We performed a retrospective cohort study of EMS cases with an impression of allergic reaction and who received epinephrine recorded in the 2014 Michigan EMS Information System (MI-EMSIS)...
