Abstract

Inhaled beclomethasone dipropionate aerosol is a topically active corticosteroid that has proved to be of great value in treating asthma. The authors have examined the effect of inhaled beclomethasone dipropionate aerosol on circulating leukocytes and on immunological measurements in normal adult subjects. Subjects inhaled either 400 micrograms or 1600 micrograms as a single dose. White blood cell counts, total neutrophil counts, total eosinophil counts and total lymphocyte counts were determined at 0, 2, 4 and 6 hours following an 8:00 a.m. inhalation. Among the 11 subjects who inhaled 400 micrograms, the total white blood cell count increased significantly at six hours (p less than 0.05). The total neutrophil count was increased significantly at 2, 4 and 6 hours (p less than 0.05). Total eosinophil counts and total lymphocyte counts were diminished but not significantly. Among the five subjects inhaling 1600 micrograms similar findings were observed. Seventeen volunteers inhaled 200 micrograms of beclomethasone dipropionate qid for 24 hours. In addition to the above studies, T and B cell numbers were determined and lymphocyte transformation studies were performed. Although trends similar to those observed with single larger d...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
