Abstract:

Ten White children with bronchial asthma and exercise-induced bronchoconstriction were assessed immunologically before and 1, 3 and 6 months after the commencement of standard therapy supplemented with ascorbate 1 g/d. The tests of cellular immune function were neutrophil chemotaxis, phagocytosis and resting and stimulated nitroblue tetrazolium reduction, and lymphocyte mitogen-induced transformation. Humoral functions measured were secretory IgA, serum immunoglobulins, alpha 1-antitrypsin, C3, C4 and total haemolytic complement, antistreptolysin O (ASO) and C-reactive protein. Radio-allergosorbent testing to the common allergens Cynodon dactylon (grass), Dermatophagoides pteronyssinus (mite), house dust and cat epithelium was performed on each child before and 3 and 6 months after treatment. Two children had depressed neutrophil motility, 4 had depressed lymphocyte transformation, and 7 had elevated levels of ASO. These functions normalized after 6 months of ascorbate-supplemented therapy. Serum total IgE levels but not specific IgE levels were likewise reduced after 6 months of therapy. Reduced levels of serum alpha 1-antitrypsin were observed in 2 children, and remained unchanged throughout the study.
