    Description / Table of Contents: Zusammenfassung In einer mehrjährigen Verlaufsstudie werden 2 Patienten mit einer Autoimmun-Thrombozytopenie und 2 Patienten mit einer autoimmunhämolytischen Anämie vom Wärme- bzw. Kälteantikörpertyp beschrieben, die nach der Splenektomie und langfristiger Steroidbehandlung keine Dauerremission zeigten. Eine langfristige klinische Besserung wurde durch Azathioprin erreicht. Während der immunsuppressiven Therapie wurden die Titer der Serumimmunglobuline gesenkt. Hierzu korrelierend konnte im Tierversuch eine vergleichbare Abnahme der Serumimmunglobuline nach der Splenektomie bzw. nach der Azathioprinbehandlung beobachtet werden. Im Gegensatz zum klinischen Erfolg der immunsuppressiven Therapie blieben die spezifischen Immunreaktionen der Patienten unbeeinflußt. Im Hinblick auf einen Auslaßversuch von Azathioprin, der zu einer schweren hämorrhagischen Diathese führte, wird hervorgehoben, daß der autoimmunologische Prozeß dieser Erkrankungen nicht unterbrochen wird solange die Autoantiköpertiter in vitro nachzuweisen sind.
    Notes: Summary Despite the clinical improvement in 4 patients with refractory autoimmune thrombocytopenia and autoimmune haemolytic anaemia treated with azathioprine, no decline in the antibody titre was observed whereas the synthesis of immunoglobulins was depressed. In experimental animals, the inhibitory effect of splenectomy and azathioprine on the immunoglobulin synthesis was confirmed. The missing correlation between the clinical improvement and persisting antibody levels is pointed out.

    Notes: Abstract We determined the lymphokines involved in the immune response to epicutaneously applied dinitrofluorobenzene (DNFB), a sensitizer, and dinitrothiocyanobenzene (DNTB), a tolerogen. Hapten-dependent T-cell proliferation and production of interleukin-2, interleukin-3 and interleukin-4 by lymph node cells (LNC) in mice painted with these cross-reactive haptens were measured by specific lymphokine assays. Proliferation of LNC in tolerized animals was lower than in sensitized mice. LNC from DNTB-treated mice produced lower amounts of interleukin-2, interleukin-3 and interleukin-4 than cells from DNFB-painted mice. These results may explain hapten-specific tolerance induced by DNTB which results in deficient production of both type 1 T-helper cell (Th1) and type 2 T-helper cell (Th2) lymphokines in response to hapten re-exposure. Deficient interleukin-4 production by cells from tolerized mice was corrected by the addition of exogenous interleukin-2. The suppressor function of adoptively transferred T cells from animals tolerized with dinitrothiocyanobenzene may be related to a shift in the balance of Th1 and Th2 lymphokines in favour of the latter, since recipient T cells might provide the source of interleukin-2 that induces interleukin-4 production by donor T cells.
