The prevalence of work-related asthma, rhinitis and urticaria was measured in a scientific establishment working with locusts. Twenty-six percent of those handling the locust in the research centre had work-related wheeze or breathlessness, and one-third had work-related rhinitis and urticaria. Work-related symptoms were uncommon in scientists exposed to locusts in the field, and in other employees at the centre. Antigens were prepared from the locusts, Schistocerca gregaria and Locusta migratoria, as well as the moth, Chilo partellus, which was also bred at the centre. Skin prick testing with the locust antigens showed positive reactions in 55% of the atopic workers at the centre, but were also present in 43% of unexposed atopic workers. In this latter group there was a correlation between positive reaction to locust and dermatophagoides antigens. Atopic workers handling the locusts developed occupational asthma more often and more quickly than similarly exposed non-atopic workers. IgG and IgE antibodies to the locust antigens were found to correlate significantly with both the degree of exposure and the presence of disease.

This communication describes the first known report of sulindac-induced anaphylaxis. A 17-year-old patient who ingested a single tablet of sulindac developed pruritus, hives, and dyspnea. Blood pressure was not detectable. The patient was treated with epinephrine, a corticosteroid, and an antihistamine. Recovery was complete. The ability of this class of drugs to produce dangerous reactions is discussed.

Cefotiam (CTM) is one of the most popular cephem antibiotics in Japan. Recently we experienced two cases of nurses with CTM-induced contact anaphylaxis. When they were preparing drip infusions of antibiotics or working around other nurses doing so, they suddenly fell into shock with other symptoms such as flushing, urticaria, abdominal distress, vomiting, dyspnoea and/or loss of consciousness. The symptoms never occurred after they avoided exposure to CTM. Passive cutaneous or open patch tests were positive for CTM. Histamine release was induced by CTM from washed leucocytes. RAST analysis using CTM-human serum albumin-coupled discs showed high % RAST count, suggesting that these reactions were mediated by IgE antibodies. A RAST inhibition test suggested that the methyl-thiotetrazole side-chain was the main antigenic determinant. Both patients had hand dermatitis that had appeared preceding the episodes of anaphylaxis. Although the dermatitis had been resistant to treatments, it also disappeared after they avoided exposure to CTM. It seemed likely that it was also induced or exacerbated by CTM and facilitated the penetration of CTM to cause anaphylaxis. The literature is also reviewed.

We identify and describe clinical findings in hypocomplementemic urticarial vasculitis syndrome (HUVS), an uncommon to rare illness related to systemic lupus erythematosus (SLE). A patient with recurrent, idiopathic urticaria-like lesions was diagnosed as having HUVS if a lesional biopsy showed leukocytoclastic vasculitis, the serum C1q was markedly decreased, and antibody to C1q was detected in the patient's serum. The clinical characteristics, serologic findings, and outcome of patients who met these criteria were determined from prospective and retrospective data, including hospital and office records, patient interviews, previously banked serum samples, and freshly drawn sera. Eighteen patients with HUVS were identified, and high incidences of angioedema, ocular inflammation, glomerulonephritis, and obstructive pulmonary disease were found. Renal and lung biopsies showed mesangial or membranoproliferative glomerulonephritis and severe pulmonary emphysema without vasculitis. Pulmonary function was measured in 17 patients, 11 of whom had dyspnea. All dyspneic patients had moderate to severe airflow obstruction, which progressed in all 11 and subsequently improved in only 1. Six of these 11 patients died of respiratory failure, 1 underwent lung transplantation, and 3 of the remaining 4 have moderately severe to life-threatening respiratory insufficiency. Treatment did not appear to alter the progression of obstructive lung disease. In contrast, renal insufficiency improved with treatment in 2 of 2 patients. Angioedema, ocular inflammation, obstructive lung disease, and glomerulonephritis appear to be common in HUVS, and lung disease causes substantial morbidity and mortality. The pathogenesis of HUVS may involve humoral autoimmunity, although it is not clear how autoimmunity would participate in development of obstructive lung disease. Cigarette smoking appears to be a risk factor for fatal lung disease in HUVS. All patients with HUVS should be made aware of this possibility and should be advised, encouraged, and helped to avoid tobacco smoke.

We report the case of a 33 year old atopic female patient, who worked for the last 4 years as a cleaner in the surgical area of a hospital. One year after starting the work in this area, the patient noticed upper respiratory symptoms and soon later dyspnea immediately after entering the operating room. Other allergic symptoms were perennial rhinoconjunctivitis and urticaria after contact with peaches. Common skin prick tests were positive for Dermatophagoides pteronyssinus. Fifteen min later a skin prick test with latex was done with a strong positive result after 10 min. At the same time, several allergens (cat dander, grass and olive pollens) showed positive results. The patient experienced a fall in the FEV1 that returned to basal levels after two inhalations of a bronchodilator. New skin tests to common allergens performed one week later were only positive to mites.

A 14 years old boy experienced an anaphylactic reaction of dyspnea, vomiting, urticaria and hypotension after he ate sunflower seeds. Specific IgE-mediated hypersensitivity to sunflower seen extract was demonstrated by skin tests and radioallergosorbent test (RAST). By immunoblotting test analysis (SDS-PAGE, Western blotting method), the allergenic activity of sunflower seem were shown to be in the MW range of 13.5 Kd.

An 18-year-old girl experienced anaphylactic reactions three times and frequent urticaria with exercise after meals that included wheat. Allergy evaluation showed a strong prick test reaction to wheat, and RAST score was 2 for wheat. Exercise provoked a decrease of FEV1 of 7.4% and increase of plasma histamine with no symptoms. Exercise after eating wheat provoked an FEV1 decrease of more than 18.7%, further increase of plasma histamine, urticaria and mild dyspnea. Oral administration of disodium cromoglycate before ingestion of bread and exercise challenge caused a maximal FEV1 increase of 6%, no increase of the plasma histamine, and no symptoms.

In 1993, 4521 schoolchildren in Oslo, Norway, participated in a European study on air pollution and respiratory health. Incorporated in the primary questionnaire were five questions taken from a study performed 12 years earlier on 1772 schoolchildren in the same city. The response rate was 85% in 1993 vs 95% in 1981. The current and cumulative prevalences of doctor-diagnosed asthma in 1993 were 4.2% and 8.0%, respectively, compared to 2.2% (P < 0.01) and 3.4% (P < 0.01) in 1981. Attacks of breathlessness during the last 3 years were experienced by 7.1% in 1993 and 3.3% in 1981 (P < 0.05). Wheezing or breathlessness on exposure to pollen in 1993 and 1981 was reported by 6.1% and 3.7% (P < 0.01), respectively; to animals by 4.0% and 2.8% (P < 0.05); and to exercise by 10.2% and 4.8% (P < 0.01). The prevalence of occasional wheezing and the cumulative prevalence of doctor-diagnosed eczema, urticaria, and hay fever were not significantly altered. To summarize, a higher prevalence of both doctor-diagnosed asthma and symptoms of obstructive airways disease was reported by children attending primary school in Oslo in 1993 than 12 years earlier. No increase was observed in the prevalence of other atopic diseases.

A 31-old male nurse of anesthesiology was exposed to rubber gloves over a period of ten years. An atopic diathesis was known. From time to time he had episodes of pollinosis. Since nine months he had suffered from conjunctivitis, rhinitis and shortness of breath while wearing latex gloves. During a night shift ten minutes after consumption of tropical fruit (bananas, kiwi) he had to care for a patient in the emergency room. He wore rubber gloves and had to clean the emergency room. Initially, his palms and feet itched. Then he experienced angor and increased perspiration 90 seconds later he suffered severe dyspnea and dysesthesia in the lower extremities. Treatment with theophylline and beta sympathomimetics, steroids and antihistaminics was successful. This male nurse had a positive history for contact urticaria after exposition to rubber. He suffered a dramatic exacerbation when wearing latex gloves and inhaling latex-contaminated air after eating tropical fruits. Fruit could have been a potent booster. Hospital employees with a history of atopic disease should be screened for potential latex allergy before occupational exposure.

Nowadays the pollens are the principal allergens implicated in anaphylactic reactions. Now one of our observations is of a case history of recurring acute urticaria, with malaise, hypotension, Quincke's oedema and dyspnea, linked with Aspergilus. The etiology is based on clinical observation, skin tests and specific IgE with a significant atopy. This observation shows that the anaphylactic reaction can also be associated with a mould such as Aspergillus.
