    Description / Table of Contents: Zusammenfassung Die Verfasser fanden bei Hapten-bedingten Krankheiten den Präalbumingehalt im Serum verringert und die relative Zahl der Präalbumin-tragenden Lymphocyten erhöht. Ihre immunfluorescenzmikroskopischen Untersuchungen ließen bei allergischer Kontaktdermatitis- und Arzneimittelallergie-Patienten in den Gefäßwänden Präalbuminablagerung und in der Dermis Präalbumin-positive Entzündungszellen (Granulocyten, Lymphocyten, Makrophagen) feststellen. Bei arzneimittelallergischen Patienten konnte von der Membran der Lymphocyten ein mitogen wirksames Agens, offenbar ein Antigen, eluiert werden, welches in einigen Fällen auch Präalbumin enthielt. Diese neueren Befunde unterstützen ebenfalls die frühere Hypothese der Autoren von der Hapten-tragenden Rolle des Präalbumins.
    Notes: Summary A significant decrease of serum prealbumin levels and an increased proportion of prealbumin bearing lymphocytes in peripheral blood have been found in patients of hapten-induced diseases. Prealbumin deposition in the vessel walls, and/or prealbumin positive cells (granulocytes, lymphocytes, macrophages) in the dermis have been observed in patients with proved drug allergy as well as allergic contact dermatitis using immunofluorescence technique. The eluates from membrane of lymphocytes of patients with drug allergy contained a mitogenic substance, probably antigen and sometimes prealbumin as well. These results also support the earlier suggested hypothesis that the prealbumin may act as a hapten carrier protein.

    Description / Table of Contents: Zussammenfassung Der autologe Epidermis-Extrakt löste bei 4 von 5 an Pemphigus vulgaris (PV) und bei 6 von 7 an bullösem Pemphigoid (BP) leidenden patienten eine Leukocytenmigrationshemmung aus. Das auf ähnliche Weise hergestellte Antigen verursachte bei Patienten mit bullöser Verbrennung oder Arzneimittel-Allergie keine Migrationshemmung. Die migrationshemmende Wirkung klang zur Zeit der Symptomfreiheit sichenden erhaltenden Therapie ab. Diese Befunde deuten darauf hin, daß die PV- und die BP-Kranken über gegen epidermale Antigene gerichtete celluläre Autoimmunreaktion verfügen.
    Notes: Summary Lymphoid cells from 4 of 5 patients diagnosed as pemphigus vulgaris (PV) and 6 of 7 patients diagnosed as bullous pemphigoid (BP) demonstrated specific cell-mediated immunity by the production of migration inhibitory factor (MIF) in the presence of autologous epidermal saline extracts. Clinical treatment of these patients with immunosuppressive agents resulted in a state of unresponsivenes of their lymphoid cells to similar concentrations of the antigen. Controls consisted of lymphoid cells from patients with bullous burns or various drug allergies which failed to show significant MIF production in the presence of autologous skin extract. These studies suggest that both PV and BP patients posses cell-mediated immunity (CMI) to their own autologous tissue antigens and this CMI may play a role in the pathogenesis of these diseases.
