Ketotifen in pollen-induced asthma: a double blind placebo-controlled study.

Twenty-nine children with an average age of 10.5 years were studied with respect to the protective effect of ketotifen on pollen-induced bronchial asthma. All of them were sensitive to deciduous tree pollen, the diagnosis being verified by bronchial challenge. The children were stratified in matched pairs and randomly allocated to two treatment groups, placebo or ketotifen 1 mg twice daily. The study was double-blind and was performed during the whole of the deciduous tree pollen season. Daily pollen counts were made, allergic symptoms were noted, additional medication was given and the expiratory pulmonary flow was recorded. During the birch pollen peak the ketotifen group showed significantly fewer, and less severe asthma and rhinoconjunctivitis than the placebo group. The anti-asthmatic medication was also used significantly less than in the placebo group. Ketotifen appeared to have good protective properties in the treatment of pollen-induced asthma and rhinoconjunctivitis.

Cord blood T lymphocyte subpopulations in premature and full-term infants.

Cord blood lymphocyte preparations from premature and full-term infants were examined for T cell subsets using monoclonal antibodies. The number of T cells in relation to the total number of lymphocytes, the proportions of T helper (Th), and T suppressor (Ts) phenotypes, respectively, were the same in preterm infants of gestational age (GA) 26-36 weeks and term infants (GA 38-41) weeks). There was no correlation between GA and Th/Ts ratio. The relative number Ts was significantly lower in infants than in adult women.

The relevance of anti-food antibodies for the diagnosis of food allergy.

All individuals are exposed to large amounts of potentially immunogenic food proteins. Most people respond by producing IgG, IgA, or IgM antibodies. The presence of such antibodies in serum is a normal, but not necessarily physiologic phenomenon. In certain groups of individuals, such as young infants, persons with a selective IgA deficiency and patients with inflammatory gastrointestinal disorders, especially high levels of such antibodies are commonly found despite complete tolerance to intake of the food in question. Obviously the finding of IgG, IgA or IgM antibodies to food proteins in serum is of limited clinical relevance. The presence in serum of IgE antibodies to food antigens is not uncommon in some patients with atopic dermatitis, although the clinical relevance of the antibodies for the dermatitis is not always clear. Young, atopic children have low levels of such antibodies as a normal, transient phenomenon. High concentrations of IgE antibodies not only to classical food antigens such as egg, fish, cow's milk, nuts, shellfish, peanuts and cereals but also to less typical allergens such as celery, some spices and other vegetables often indicate a pronounced food allergy that can give rise to a serious reaction upon contact. In contrast to the case with non-IgE antibodies, the presence of IgE antibodies in serum is a non-physiologic state of clinical relevance.

Comparison of the protective effect of ketotifen and disodium cromoglycate on exercise-induced asthma in asthmatic boys.

Fourteen boys with a mean age of 12.2 years were studied with respect to the protective effect of ketotifen on exercise-induced asthma (EIA) in comparison with disodium cromoglycate (DSCG). All had a positive history of EIA and a post-exercise fall in FEV1 of more than 20%. A double blind cross-over technique was used with a 1 week wash-out period between the two treatment alternatives. Both drugs gave some, but not significant protection for EIA and no differences between the two active substances tested were found. Great individual differences in the response to the two drugs were noted.
