Reaginic and non-reaginic antibodies against mammalian danders.

Solid phase enzyme immunoassay (EIA) and passive haemagglutination techniques were used to study the occurrence of IgG-type antibodies against feline and bovine epithelial extracts among RAST-positive patients, senior veterinary students, cat fanciers (representing exposed subjects) and healthy controls. In most groups both techniques exhibited equal sensitivity being positive in about half of the RAST-positive cases. The levels of both EIA-reactive IgG-class and IgA-class antibodies were increased in most of the sera (greater than mean + 2 s.d. of controls), while only a few sera showed increased IgM values.

Haemagglutinating antibodies to cat dander in relation to exposure and respiratory allergy.

Cat epithelial extract was coupled with chromic chloride to red cells and used as an antigen in a haemagglutination assay. Agglutinins coexisted with IgE type antibodies in 44% of patients with respiratory allergy and sensitivity to cat dander but occurred in only 1% of asthmatic patients sensitized to other allergens or in controls. The agglutinins were detected in six out of 104 cat fanciers, and three of those with agglutinins had asthma. The agglutinins were of IgG type and were heterogeneous in specificity.

Unsuitability of bakery work for a person with atopy: a study of 234 bakery workers.

A disease of the atopic group was established in 25% of bakery employees investigated: 9% had asthma, 25% allergic rhinitis and 5% atopic eczema. The definite role of flour dust as an allergen maintaining asthma was established in 14 of 21 bakery employees with asthma. The onset of asthma in bakery work occurred after an average of 4.2 years of exposure to flour dust. The study revealed that 71% of the bakers suffering from an atopic disease had close relations with a history of atopic disease, whereas the corresponding percentage for the healthy group was 17. The results indicated that no person with current atopic disease or earlier signs of one should be given employment in the bakery branch. A relative bar to employment appears to be also the occurrence of these forms of diseases in the applicant's close relations.

Comparison of the effect of the beta1-blocking drugs atenolol and metoprolol on bronchial asthma.

Twenty patients with severe or medium severe asthma were given atenolol (Atenol ICI-Pharma) and/or metoprolol (Seloken Hässle) for tachycardia, hyperkinetic tremor, arterial hypertension or symptoms of angina pectoris. These cardioselective beta-blocking drugs caused only a very slight decrease in PF values. There was no difference between atenolol and metoprolol as regards the PF values. A 24 hourly dose of 100 mg atenolol caused a distinct fall in diastolic fall in diastolic pressure as compared with the same amount of metoprolol. Both these two beta1-blockers moderated the tachycardia which occurs in asthma; atenolol in this dose had a slightly stronger action. The subjective condition of five patients with severe or medium severe asthma was considerably relieved by atenolol and/or metoprolol. The relief manifested as a lessening of dyspnoea and improvement of the general status. No essential change was observed in the PF values despite the subjective effects. The most noteworthy change was the amelioration of tachycardia which had continued longer than expected in these patients. The heart rate dropped from 140-120/min to 90-70/min and dyspnoea was relieved at the same time.

Immunoglobulin E specific to wheat and rye flour proteins.

We have used the radioallergosorbent test (RAST) to determine IgE antibodies specific to wheat flour proteins in the sera of seven groups of patients. In some cases rye-specific IgE was also determined. Wheat and rye RAST scores showed a good correlation, presumably due to cross-reactions. Among bakers with asthma, positive scores, 0.5-3, occurred with a prevalence of 43%, and among children with eczema, scores in the range 0.5-4 were found with a prevalence of 54%. A score of 0.5 was a marginal value which was also occasionally encountered with sera from patient groups with no history of immediate hypersensitivity to wheat or rye. These groups included adults and children with allergic rhinitis and asthma, children from the general population and children with coeliac disease. The RAST appeared useful in the diagnosis of allergy to inhaled flour dust among bakers. Among children with eczema, positive wheat and rye RAST results were a common finding, which only occasionally could be linked to strong and unequivocal reactions to the foods in question. Both in bakers and children with eczema, wheat and rye RAST results showed good agreement with intracutaneous skin test results.
