Criteria for hysterical psychosis set forth by Hollender and Hirsch were systematically applied to a representative sample of 217 patients hospitalized for the first time in their lives for functional psychiatric illness. Surprisingly, no patients who met all of these criteria were found.
The role of T cells in the regulation of IgE synthesis by human PBMC was studied. PBMC or separated and recombined populations of T and B cells from both normal and atopic donors were cultured for 10 days with and without cycloheximide. IgE and IgG synthesis were determined by specific RIA. IgE synthesis was detected in 0/30 non-atopic, 6/34 mildly atopic and 25/31 severely atopic subjects. Autologous T cells from 10/26 atopic donors, whose B cells synthesised IgE, significantly suppressed this IgE synthesis. The addition of allogeneic T cells from atopic or non-atopic subjects to atopic B cells resulted in greater suppression of IgE synthesis than the addition of autologous T cells. These data support the notion that atopic subjects have naturally occurring IgE isotype-specific suppressor T cells as well as suppressor T cells which can be activated during incubation with alloantigen.
