    Notes: We compared three treatments: sodium cromoglycate 5 mg aerosol and placebo syrup (39 patients), placebo aerosol and ketotifen syrup (39 patients), and placebo aerosol and syrup (36 patients). The patients (mean age 11.7 years) had mostly allergic, moderately severe asthma. Treatments were added to current therapy (mostly bronchodilators only) for 3 months. Aerosols were taken four times daily and syrups twice daily. The following results were significant at a level of 5%. At the final clinic visit, the changes from baseline in lung function favored sodium cromoglycate over the other treatments. During month 3, sodium cromoglycate was superior to ketotifen for night symptoms, morning tightness, daytime symptoms, and cough. Bronchodilator use decreased more with sodium cromoglycate than ketotifen. Patients’ and clinicians’ overall opinions of treatment effectiveness favored sodium cromoglycate over ketotifen and placebo. In these patients, sodium cromoglycate was both effective and superior to ketotifen.

    Notes: Background: The aim of the present study was to determine the existence of sensitization to the fungus Hemileia vastatrix (coffee leaf rust) in a sample of the Brazilian population. This fungus attacks coffee plantations, and in some regions of Brazil the concentration of its spores in the air can be very high. Methods: A total of 378 individuals underwent skin tests (prick and intradermal tests) with H. vastatrix extract. The subjects were divided into four groups according to the occurrence of atopy and the region where they lived (coffee-growing or non-coffee-growing regions), and another group (V) consisted of 50 rural workers employed on coffee plantations. The presence of specific IgE against the fungus H. vastatrix in sensitized individuals was demonstrated in vitro by immunoblotting. Results: There was no statistical difference in comparing the results with intradermal or prick tests. The incidence of positive tests was significantly higher among atopic individuals residing in coffee-growing regions (14.7%). Among rural workers, 10% showed positive tests. Immunoblotting revealed specific IgE against 20 protein bands of H. vastatrix. Conclusions: The fungus H. vastatrix may be an important allergen in coffee-producing countries. The sensitization is more frequent among atopic individuals residing in coffee-growing regions.
