Characterization of T cell subsets in patients with atopic dermatitis using OKT monoclonal antibodies.

The distribution of T cell subsets has been studied by means of OKT monoclonal antibodies in 19 children with atopic dermatitis. In these patients a decreased percentage of circulating OKT4+ cells has been observed, while no difference has been found between atopic and normal subjects, regarding the percentages of circulating OKT8+ and OKT11+ cells. An increased OKT4+/OKT8+ ratio has been detected only in three children with a particularly severe and extensive atopic eczema.

Evaluation of allergic etiology in perennial rhinitis.

In 197 patients with perennial rhinitis, 49 patients (24.9%) were found to be allergic to perennial inhalant allergens, 37 patients (18.8%) allergic to seasonal allergens, 52 patients (26.4%) had food intolerance, 12 patients (6.6%) showed evidence of nasal infection, and in 46 patients (23.3%) etiology was undetermined.

Functional characterization of specific IgE antibodies for tetanus toxoid.

The specific IgE response that appears in subjects immunized with tetanus toxoid does not induce hypersensitivity reactions at subsequent immunizations. The type I immune response, therefore, was studied both in vivo and in vitro, in 11 subjects who had specific IgE antibodies for tetanus toxoid. The results showed that: 1. the specific IgE antibodies are heterogeneous regarding their affinity for the mast cell and basophil receptors; 2. the specific IgG antibodies for tetanus toxoid, at serum concentrations, are not able to interfere with the in vitro specific basophil degranulation; 3. in the PEG precipitate there are aggregates of specific IgE antibodies for tetanus toxoid. In vitro, these molecular aggregates are not able to sensitize the basophil cells.
