Allergic reactions to insect stings and bites.

Insect stings are an important cause of anaphylaxis. Anaphylaxis can also occur from insect bites but is less common. Insect venoms contain several well-characterized allergens that can trigger anaphylactic reactions. Effective methods to diagnose insect sting allergy and assess risk of future sting reactions have been developed. Management strategies using insect avoidance measures, self-injectable epinephrine, and allergen immunotherapy are very effective in reducing insect-allergic patients' risk of reaction from future stings. Diagnostic and management strategies for patients allergic to insect bites are less developed.

[Diagnosis in 1348 patients which consulted for a probable spider bite or insect sting].

Accumulate experience, from 1955 to 1995, in an outpatient university parasitology clinic in Santiago, with 1,384 patients referred from diverse public and private medical institutions because of a probable spider bite or insect stings, is presented. It is noteworthy that only 618 (44.7%) of consultations corresponded to clinical conditions originated by arthropods, whereas from the remaining 766, 612 (44.2%) were due to a bacterial, viral or parasitic etiology and 154 (11.1%) were caused by physical or chemical agents. Frequency of diagnosis was: loxoscelism 16.6%, spider bites (excluded Loxosceles laeta) 1.3%, scorpion sting 0.9%, tick stings 2.2%, insect bites 23.7%, impetigo 6.6%, folliculitis 11.3%, boil 22.7%, erysipelas 0.1%, pustula maligna 0.3%, herpes simplex 2.5, palpebral herpes zoster 0.3%, acute Chagas' disease 0.4%, angioneurotic edema 0.1%, ecchymosis 3.0, contact dermitis 7.8% and chemical dermitis 0.2%. These frequencies do not indicate the real occurrence of the diagnosed nosologies, but what happened in a specialized outpatient clinic dealing cheaply with parasitic diseases and arthropod envenomations. Description of relevant clinical features and epidemiological considerations of pathology observed, conjointly with differential diagnosis are presented.

Stinging and biting insect allergy: an Australian experience.

BACKGROUND: Stings and bites from various insects are responsible for many anaphylactic events. OBJECTIVE: To document the clinical features of specific forms of anaphylaxis and investigate clinical concerns regarding stinging and biting insect allergy. METHODS: All patients presenting for evaluation of adverse reactions to insect stings or bites between December 1980 and December 1997 had the clinical details of their reactions recorded and their reactions classified. RESULTS: The spectrum of clinical symptoms and signs is similar to that seen in anaphylaxis from other sources; stings on the head or neck are not more likely to cause life-threatening reactions than stings elsewhere on the body; a lesser reaction will not necessarily lead to a more serious reaction from a future sting; asthmatic patients do appear to have an increased risk of asthma as a feature of their anaphylactic response; anaphylaxis is usually confined to a particular insect species for the individual patient; patients who have had multiple stings at one time may have experienced true anaphylaxis and not a "toxic" response; and patients who have had anaphylaxis from other sources are at no greater risk than that of the general population of reacting similarly to insect stings or bites. CONCLUSIONS: Anaphylactic events from insect stings show the same clinical features as those from other sources. Systemic reactions seem confined to a specific insect species. Patients who experience RXN3 reactions from multiple stings at one time should undergo specific venom testing, because many have experienced true anaphylaxis and not a toxic response. Future consideration should be given to the role of beta-adrenergic antagonists and ACE inhibitors in patients with systemic reactions.

Allergy to stinging and biting insects in Queensland.

Over an eight and a half year period 742 patients were assessed for allergy to stinging and biting insects in Queensland; 452 (61%) had allergic reactions to honey bees, 244 (33%) to wasps, 30 (4%) to various ants, 11 (1.5%) to march flies (Tabanus sp.) and five to tick infestation. One hundred and fifty one patients (20%) presented with large local swelling only (RXN1), 98 (13%) with urticaria and/or facial angioedema distant from the sting site (RXN2) and 492 (66%) with subjective or objective evidence of dyspnoea or hypotension (RXN3). Allergy testing was performed with honey bee and wasp venoms by skin testing or by Radioallergosorbent testing. Fifty nine patients (30%) with RXN3 responses to wasps failed to react to either test, while this applied to only 19 (6%) of the patients with RXN3 responses to bee stings. Thus, a large number of wasp-allergic patients with RXN3 responses could not be offered immunotherapy. A similar problem exists in the lack of availability of specific reagents for anti- and tick-induced dyspnoea or hypotension. A whole-body insect extract of march fly, however, appears useful.
