[Eczema and hyper-IgE. Effect of cephalosporins]

Atopic dermatitis is a disease in which staphylococcal cutaneous superinfection and immune disorders, especially hyper IgE, are closely related. Cephalosporins are very effective on exacerbations of superinfections; among them, Cefadroxil diminishes immunoglobulins E in vivo. In vitro, this antibiotic promotes from the macrophage the PgE2 synthesis to which the T suppression is classically sensitive. In DNP-OVA sensitized rats which produce anti DNP IgE, the secondary response is inhibited by Cefadroxil. From clinical to research experiments, the hypothesis is the effect of cephalosporins, and especially Cefadroxil, on IgE synthesis.
