Ninety patients suffering from recurrent urticaria were orally exposed to 500 mg acetyl salicylic acid (ASA). 36.6% proved to be ASA intolerant in this group. 26 ASA-positive and 18 ASA-negative probands were selected to take part in an additional provocation test with 8 different food additives (preservative and colouring matters). Altogether 31 tests sheets were exaluated. Urticarial reactions were seen after administration of p-hydroxybenzoic acid methylester (5), p-hydroxybenzoic acid propylester (6), benzoic acid (9), sodium benzoate (6), tartrazine (6). Ponceau rouge (5) and indigo carmine (3). Detailed research was carried out on the occurrence of the tested substances. With a diet avoiding salicylates, benzoates and colouring matter 20% of these patients recovered spontaneously and became symptom-free, whilst a further 55% of cases showed marked improvement.

Sixty patients of ages ranging from 11 to 64, with chronic urticaria from 2 months to 50 years duration, were studied with the provocation test. We found responses in 33.3% of patients. Tartrazine was the most common inducer, specially in those patients sensitive to aspirin with increased salicilate blood levels. As we did not use aspirin as inducer the results with tartrazine are more relevant and can be used to detect a positive response to aspirin. The relation between tartrazine and aspirin was not observed in patients with pressure or cholinergic urticaria. The provocation test is most useful in patients with chronic urticaria of unknown cause. 4 hydroxybenzoic acid and sodium acid and sodium benzoate were the more common inducers in the latter patients. We feel that the provocation test is a useful tool to study patients with chronic urticaria. Tartrazine, 4 hydroxybenzoic acid, sodium benzoate, tiramin and penicilin are included in the test. The responders should eliminate the offender from their diet.

In 131 patients with chronic urticaria, including physical urticarias, oral provocation tests were done with aspirin. A total of thirty-one patients showed a reaction on aspirin challenge. Reactions were seen in 35% of patients with idiopathic urticaria, 52% of patients with cholinergic urticaria, and 43% of those with pressure urticaria. The patients with reactions to aspirin were also tested with tartrazine, sodium benzoate, 4-hydroxybenzoic acid, sodium- and phenyl salicylate and the analgesics indomethacin, paracetamol and mefanamic acid. In nineteen of twenty three aspirin sensitive patients, positive reactions to one or more of these substances were observed. Indomethacin and tartrazine had the highest scores. There was no statistically significant correlation between aspirin reactions and the presence of nasal polyposis, sinusitis, asthma or atopy.

IgE levels in faecal extracts (Copro-IgE levels) were investigated in food allergy (FA) patients before and after the challenge test administration of food allergens. IgE levels were measured by time-resolved fluoroimmunometric assay. In addition, the effects of administration of oral sodium cromoglycate (SCG) on the Copro-IgE levels were studied. Copro-IgE levels in patients with FA, who were placed on an elimination diet, did not differ from those of healthy children. After a challenge test immediate symptoms of urticaria and wheezing were observed in all FA patients. Copro-IgE levels in each patient increased markedly within 24 h of the challenge test. Moreover, FA patients treated orally with SCG showed neither the increase in Copro-IgE levels nor any remarkable symptoms after the challenge. Our results suggest that the increased Copro-IgE levels may be a specific consequence of the local immune response to food allergen stimulation in the gut mucosa.

Human urine samples, purified on octadecasilyl-silica cartridges, contained immunoreactive angiotensin I, II, arginine vasopressin and oxytocin. The daily excretion of these peptides in healthy volunteers was 190.00 +/- 38.43 (n = 12), 17.48 +/- 3.09 (n = 12), 63.43 +/- 14.84 (n = 8) and 13.52 +/- 1.42 (n = 7) pmol/24 hr, respectively (mean +/- s.e.m.). Patients with a history of anaphylactoid reactions to drugs or food additives showed clinical symptoms such as urticaria, flush, nausea, dizziness and hypotension after oral provocation with cyanocobalamine, propyphenazone, acetylsalicylic acid and sodium benzoate. In five of the seven patients, angiotensin I and II were increased several fold in the urine fractions after symptoms were reported. The average increase in the urine concentration of both peptides was fourfold and 5.5-fold. In three out of five patients, the mean excretion of arginine vasopressin and oxytocin immunoreactive material was also elevated by a factor of 5.7 and 4.4, respectively. Oral provocation with a placebo failed to elicit anaphylactoid symptoms or an increase in the urine levels of angiotensin I or angiotensin II. Angiotensin I and angiotensin II-like immunoreactivity could be characterized on HPLC as Ile5-angiotensin I, Ile5-angiotensin II and angiotensin II metabolites. HPLC characterization of immunoreactive arginine vasopressin and oxytocin in two different gradient systems showed retention times different than the retention times of the corresponding synthetic standard peptides indicating that both peptides are not authentic AVP and OXT. These results suggest that angiotensin I and angiotensin II may be involved in the clinical events observed during some forms of anaphylactoid reactions.

We examined 70 patients reporting hypersensitivity reactions caused by latex articles. All patients suffered from urticaria, 36 from rhinitis, 31 from conjunctivitis, 22 from dyspnea, and 17 from systemic reactions, and four patients developed severe systemic complications during surgery. By means of inhalative challenge tests with powdered latex gloves, it could be demonstrated that the glove powder (cornstarch) obviously functions as a carrier for latex allergens, which then become airborne. Five of 18 patients undergoing such challenge tests demonstrated a significant increase of specific airway resistance; 17, acute rhinitis and/or conjunctivitis; and two, a systemic reaction. Sixty-two percent of the patients demonstrated specific IgE antibodies to natural latex, 58% to an irradiatively cross-linked, so-called, "hypoallergenic" latex preparation, and 46% to commercial-latex RAST disks (Pharmacia). No specific antibodies to cornstarch or a mixture of rubber chemicals were found. A good correlation (82%) exists between latex IgE RAST and latex skin prick test, as revealed in a subgroup of 45 subjects. By means of sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the latex allergen appears to be a mixture of proteins in a molecular weight range from 10 to 67 kd.

A case of metabisulfite-induced anaphylaxis is presented in which convincing evidence of an IgE-mediated mechanism of action was found. The patient demonstrated urticaria, angioedema, nasal congestion, and apparent nasal polyp swelling following provocative challenge with sodium metabisulfite. Skin test to metabisulfite was positive as was a basophil histamine release test when the patient's cells were incubated with metabisulfite. A review of metabisulfite-induced allergic reactions in which an IgE-mediated mechanism has been demonstrated is presented.

334 electrocardiographic recordings obtained from 109 patient who underwent cerebral angiography with low osmolality contrast media (CM) were analysed. CM used in this study included meglumine sodium ioxaglate, iopamidol, and iohexol. A tachycardial effect greater than 10% was seen in 8.3% of recordings, while a bradycardial effect greater than 10% was seen in 11.1%. Assessment was based on the type of CM used, age of the patients, usage of atropine sulfate as premedication, and the vessel injected. Patients who were under 19 years of age, and unpremedicated had a significantly higher incidence of bradycardia. On the other hand, there was no significant difference of the incidence of electrocardiographic abnormality between the three CM, and between two injected vessel groups. We have also analysed the incidence of generalized adverse effect. There was no serious complication, however, 11.9% of the patients who underwent cerebral angiography with ioxaglate developed urticaria and this was significantly higher incidence than in the other two CM groups.

Historical data were obtained by questionnaire and telephone survey on 20 of 24 women with reported allergic reactions to a psyllium-containing cereal, Heartwise. Protein fractions from this new cereal, as well as from psyllium mucilloid and a psyllium-containing laxative, Metamucil, were extracted, quantitated, and separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Patients' sera were collected, and specific IgE and IgG antibodies to these psyllium antigens were detected by immunoblotting techniques. Of the 20 women evaluated, all but six were nurses. Eighteen (90%) of the women had historical and/or laboratory evidence of atopy. Exposures included ingestion or dispensing of psyllium-containing products. Only three women denied prior exposure to psyllium. Symptoms developed shortly after small amounts of the cereal were ingested and most commonly included moderate to severe wheezing, throat and chest tightness, and urticaria. All the women required medical therapy, 11 (55%) in an emergency room. Specific IgE and IgG antibodies to various psyllium protein fractions were documented in all the subjects. It was concluded that individuals sensitized by occupational exposure to psyllium dust are at high risk for allergic reactions to ingested psyllium-containing products.

Since 1979 several reports of contact urticaria due to natural latex have been well documented. Recent case reports suggest that rhinitis and asthma may also be due to rubber exposure. We describe an operating room nurse who was exposed at work to natural rubber (latex) due to the use of latex surgical gloves. After 25 years, she developed contact urticaria, rhinoconjunctivitis and acute asthma following the handling of rubber gloves for surgical purposes. She was symptom-free when on vacation. Skin prick testing demonstrated an immediate skin reaction to latex. Rub testing with surgical gloves was positive. Specific IgE antibodies to latex were found by indirect ELISA. Specific bronchial challenge with latex extract elicited an isolated immediate asthmatic reaction that was inhibited with cromolyn sodium pretreatment. Patch testing to common rubber additives was negative. These results suggest that latex present in surgical rubber gloves and probably acting as inhalant allergen may produce occupational asthma in exposed subjects, probably by means of an IgE-mediated mechanism.
