    Abstract:

    ABSTRACT Objective: To determine the Australian native Ant species associated with Ant Sting anaphylaxis, geographical distribution of allergic reactions, and feasibility of diagnostic venom-specific IgE (sIgE) teSting. Design, setting and participAnts: Descriptive clinical, entomological and immunological study of Australians with a history of Ant Sting anaphylaxis, recruited in 2006-2007 through media exposure and referrals from allergy practices and emergency physicians nationwide. We interviewed participAnts, collected entomological specimens, prepared reference venom extracts, and conducted serum sIgE teSting against Ant venom panels relevAnt to the species found in each geographical region. Main outcome measures: Reaction causation attributed using a combination of Ant identification and sIgE teSting. Results: 376 participAnts reported 735 systemic reactions. Of 299 participAnts for whom a cause was determined, 265 (89%; 95% CI, 84%-92%) had reacted clinically to Myrmecia species and 34 (11%; 95% CI, 8%-16%) to green-head Ant (Rhytidoponera metallica). Of those with reactions to Myrmecia species, 176 reacted to jack jumper Ant (Myrmecia pilosula species complex), 18 to other jumper Ants (15 to Myrmecia nigrocincta, three to Myrmecia ludlowi) and 56 to a variety of bulldog Ants, with some participAnts reacting to more than one type of bulldog Ant. Variable serological cross-reactivity between bulldog Ant species was observed, and sera from patients with bulldog Ant allergy were all positive to one or more venoms extracted from Myrmecia forficata, Myrmecia pyriformis and Myrmecia nigriceps. Conclusion: Four main groups of Australian Ants cause anaphylaxis. Serum sIgE teSting enhances the accuracy of diagnosis and is a prerequisite for administering species- MJA 2011; 195: 69-73 specific venom immunotherapy

  • fatal anaphylaxis following jack jumper Ant Sting in southern tasmania
    The Medical Journal of Australia, 2001
    Co-Authors: Simon G A Brown, Qixuan Wu, Robert G H Kelsall, Robert J Heddle, Brian A Baldo
    Abstract:

    The "jack jumper" Ant (Myrmecia pilosula) is a major cause of anaphylaxis in Tasmania. We describe four deaths attributed to Stings by this Ant between 1980 and 1999. All victims were men aged 40 years or over with significAnt comorbidities; two were taking angiotensin-converting enzyme inhibitors, which may increase risk of severe anaphylaxis. Three victims had known Ant-Sting allergy, but only one carried adrenaline, which he did not use. Another believed he was protected by previous attempts at hyposensitisation with whole Ant-body extract. There is potential to prevent deaths by careful education of people with known allergy, prescribing of adrenaline for auto-injection and development of an effective hyposensitisation therapy.

  • fire Ant Sting anaphylaxis in australia
    The Journal of Allergy and Clinical Immunology, 2004
    Co-Authors: Graham O Solley, C Vanderwoude
    Abstract:

    Abstract Rationale Fire Ants have only recently been detected in Australia. Methods The case reports of 2 persons who have suffered anaphylaxis from fire Ant Stings, the first in Australia. Results Ant Sting anaphylaxis in Australia is relatively common but had been restricted to Stings from native Ant species; eg of the Myrmecia sp. Colonies of Solenopsis invicta species [Red Imported Fire Ant-RIFA] were first detected in Brisbane in February 2001. Intensive measures were established to try to eradicate or at least control their spread. The 2 subjects of this report were both employed in the RIFA detection and eradication program. Subject 1. A male,47 years, had experienced at least 20 RIFA Stings resulting in the expected local pustules. He then had 2 RIFA Stings at the one time on his knee. Within 10 minutes he developed widespread pruritus followed by nasal congestion and acute chest tightness with dyspnea. The reaction subsided within 2 hours following IV saline and 200 mg hydrocortisone. Subsequent specific allergenic intradermal teSting with the RIFA reagent proved positive and as a consequence he underwent a trial of desensitization with the whole body extract [WBE-RIFA]. He has since tolerated a RIFA Sting. Subject 2. A male,49 years, had had “30” RIFA Stings resulting in the usual local responses. Then within 5 minutes of 2 RIFA Stings, he developed generalized urticaria, chest pains without dyspnea and nausea. He made a slow recovery without therapy over 2 days. Specific RIFA teSting proved positive. He is undergoing desensitization with WBE-RIFA without any problems. He has not had any further Stings.

  • anaphylaxis due to red imported fire Ant Sting
    The Medical Journal of Australia, 2002
    Co-Authors: Graham O Solley, C Vanderwoude, Gregory K Knight
    Abstract:

    The invasive Red Imported Fire Ant (Solenopsis invicta Buren) is well established at two locations in the Brisbane area, and we report a patient with anaphylaxis after a Sting. The potential for anaphylactic events in Australia due to S. invicta will be greater than for native Ants because of its unusual venom, its habit of forming supercolonies in grassy areas, and its aggressive group territorial defence, which can result in multiple Stings.
