Hymenoptera venom allergy in children.

From a taxonomic point of view, Hymenoptera are subclassified into families: Apidae, including honeybees (Apis mellifera) and bumblebees (Bombus), and Vespidae, which, in turn, are divided into the subfamilies of Vespinae (wasps, including hornets, vespules, dolichovespules) and Polistinae (paper wasp). Hypersensitivity to Hymenoptera venom can be linked to immunological (IgE-mediated or non-IgE-mediated) and non-immunological mechanisms. Reactions are classified into local reactions, large local reactions, systemic reactions, toxic reactions, and unusual reactions.

Activation of mouse skin mast cells and cutaneous afferent C-fiber subtypes by bee venom.

In mammals, many Hymenopteran stings are characterized by pain, redness, and swelling - three manifestations consistent with nociceptive nerve fiber activation. The effect of a Western honeybee (Apis mellifera) venom on the activation of sensory C-fibers in mouse skin was studied using an innervated isolated mouse skin preparation that allows for intra-arterial delivery of chemicals to the nerve terminals in the skin. Our data show that honeybee venom stimulated mouse cutaneous nociceptive-like C-fibers, with an intensity (action potential discharge frequency) similar to that seen with a maximally-effective concentration of capsaicin.

Long-term tolerance and efficacy of venom immunotherapy after an episode of Crohn's disease and ankylosing spondylitis after up-dosing.

Hymenoptera stings can cause severe anaphylactic reactions in patients with an underlying Hymenoptera venom allergy (HVA). In such cases, venom immunotherapy (VIT) is a highly effective measure to prevent future anaphylaxis. The management of patients with a clear allergological indication for VIT and contraindications to VIT (e.

BAX pores facilitate mitochondrial DNA release in wasp sting-induced acute kidney injury.

The role of B-cell lymphoma 2 (BCL2)-associated X (BAX) macropores in the leakage of mitochondrial DNA (mtDNA) and their impact on acute kidney injury (AKI) has recently been brought to the focus of researchers. This study aimed to explore the relationship between mtDNA leakage and BAX macropores during wasp sting-induced AKI. BAX mitochondrial translocation and macropores opening increased in both in vivo and in vitro models of wasp sting-induced AKI.

A rare concurrence of acute tubular necrosis and chronic glomerular sclerosis in a patient with wasp stings.

Wasp venom injections from wasp stings can damage several organs, most commonly the kidneys. Despite literature evidence, wasp sting-induced acute kidney injury (AKI) is rare and involves complex pathophysiological processes. While acute tubular necrosis (ATN) is the most prevalent histological result of wasp sting-induced AKI, uncommon combinations of chronic renal lesions have been described, alerting us to the patient's underlying illness.

Unraveling Complexities: Rhabdomyolysis, Acute Renal Injury, and Compartment Syndrome Following a Wasp's Sting.

This study delves into the rare occurrence of rhabdomyolysis induced by wasp stings, emphasizing its toxic systemic repercussions. Drawing parallels with documented instances of insect bites worldwide, including those by honey bees and Africanized bees, the research explores the correlation between multiple wasp stings and acute renal failure associated with rhabdomyolysis. The venom's active components, such as amines, kinins, and histamine-releasing peptides, underpin toxic systemic reactions, leading to hemolysis, coagulopathy, and severe cytotoxicity-induced acute renal failure.

False-Positive Iodine-131 Uptake Due to Wasp Sting.

A 38-year-old woman with papillary carcinoma of the thyroid who underwent total thyroidectomy followed by high-dose radioiodine ablation was called for Iodine-131 (I-131) whole-body follow-up scan. Her follow-up scan revealed focal tracer accumulation in the lower aspect of the right posterior neck region. Her stimulated serum thyroglobulin and anti-thyroglobulin antibodies were 0.

Cerebral venous sinus thrombosis accompanied by cerebral venous infarction and multiorgan dysfunction after wasp stings, A case report.

Introduction: The high incidence of wasp stings have been causing a variety of injuries in China, but systemic complications are rarely reported.

Case Presentation: A 59-year-old man was severely attacked by wasps. He developed an acute onset of right hemiplegia and chest distress and was admitted to our emergency department 13 hours after being attacked.
