Severe anaphylactic reaction to mediterranean jellyfish (Ropilhema nomadica) envenomation: Case report

We present a 15-year-old female patient with an anaphylactic reaction to a jellyfish sting, sustained while surfing in the Mediterranean Sea. She experienced immediate difficulty in breathing, hoarseness and itching and was taken by ambulance to the emergency department, receiving intramuscular adrenaline on the way. She presented with periorbital swelling and facial edema and improved with systemic steroids and antihistamines. She was discharged 2 days later with allergy service follow up at our institution. This is the first case report documenting anaphylaxis due to Mediterranean jellyfish envenomation.

‚ÄčA 25-year-old woman presented with a rash, and reported that she was in South Carolina when she felt a stinging sensation. That was followed by blisters on her foot.She noticed swelling of her foot, and had continued pain. She took pictures of the bite on days two and six. (Below.) She reported that she had a similar sting the previous summer. She said she had no fever, shortness of breath, or dizziness. Her vital signs were a temperature of 98.6°F, a heart rate of 80 bpm, a blood pressure of 100/60 mm Hg, a respiratory rate of 16 bpm, and an SPO2 of 100% on room air.She was alert and in no distress. Her oropharynx ...

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 22.3% of patients in this study. The most common sting type was from wasps (58.3%). Eighty-five percent of patie...

Purpose of review Guidelines on insect sting allergy and venom immunotherapy (VIT) have been updated. This review describes the evolution of these guidelines and their similarities and differences. Recent findings The US and European guidelines show the evolution of guideline development in the grading of recommendations and the transparency of the evaluation of evidence. The US and European guidelines on VIT are similar in most areas and complimentary in others. The European guidelines are limited to VIT and are based on a published systematic review; the US practice parameters cover all areas of the diagnosis and ma...

Purpose of review To update the influence of the global climate change on Hymenoptera venom allergy. Recent findings Climate change facilitates biological invasions of hymenopteran species and plays a role in the impact of introduced species relevant for human health. It contributes to a rise in the incidence of sting injuries and allergy reactions across the world. Summary Global climate change has contributed to the expansion and the redistribution of allergenic insect species, increasing the number of allergy cases caused by stinging insects worldwide. Imported insects are trending species in systemic reactions ...

Hymenoptera stings may cause both local and systemic allergic reactions and sometimes even life threatening anaphylaxis. Along with pharmaceutical drugs and foods, hymenoptera venom is one of the most common causes of anaphylaxis in humans. To date, no parameter has been identified that may predict which sensitized people will have a future anaphylactic reaction, however many risk factors such as mast cell activation syndromes associated with the severity of the re-sting reaction are known. Venom immunotherapy (VIT) is the most effective method of treatment for people who had systemic reactions to an insect sting, which is...

Tryptase is produced primarily by mast cells. Mast cell degranulation results in release of tryptase and anaphylaxis may result in elevated tryptase levels, with return to normal levels over a few hours.1 Persistent or episodic elevation of tryptase levels can be indicative of increased body mast cell burden or mast cell activation, typically seen in mastocytosis and mast cell activation disorder (MCAD).2 Elevated serum tryptase levels represent a significant risk factor for severe anaphylaxis to hymenoptera stings.

Conclusions: In the most important procedures, there is a very high compliance with the guidelines. In the areas where the guidelines are not precise, we observed a large spread of results. PMID: 31333352 [PubMed]

Conclusions: The treatment after the sting in a significant percentage of episodes still deviates from the recommendations of the guidelines, especially in the field of adrenaline recommendations for patients in case of a resting by an insect. PMID: 31333347 [PubMed]

Hymenoptera venom allergy ranks among the top three causes of anaphylaxis worldwide, and approximately one quarter of sting-induced reactions are classified as severe. Fatal sting reactions are exceedingly rare, but certain factors may entail a considerabl...
