    Notes: The effects of the novel immunosuppressant Deoxyspergualin (DSP) on the development of experimental autoimmune thyroiditis (EAT) in CBA mice were studied. For EAT induction, the mice were immunized with 100 μg of porcine thyroglobulin (p Tg) emulsified in CFA on day 0 and in IFA, for boosting, on day 14. Twenty-eight days after primary immunization, histological and serological signs of EAT occurred in control mice treated with PBS which showed marked lymphoid infiltration of the thyroid glands along with increased serum titres of anti-pTg antibodies. Development of both these EAT features was significantly suppressed when the mice were treated with 2.5 mg/kg body weight DSP, given daily, five times a week, from day —2 to day + 28 after immunization. The effect appeared to be dose-dependent and DSP was ineffective when given under the same experimental conditions at the dose of 0.5 mg/kg body weight. No DSP-toxic effects could be observed during the experiment. These results provide further evidence for the powerful immunosuppressive properties of DSP and suggest that this drug may be used in the treatment of autoimmune thyroid diseases and other T-cell mediated autoimmune disorders in humans.

    Notes: The effects of the administration of the recently discovered immunosuppressant 15-Deoxysper gualin (DSP) on the development of insulin-dependent diabetes mellitus (IDDM) in diabetes prone BB rats were studied. The data show that 2 mg/kg body weight DSP, administered six times a week from the 30th day up to the 105th day of age, significantly reduced the incidence of diabetes in diabetes-prone BB rats as compared with the PBS-injectcd controls. The drug was also able to reduce the signs of pancreatic insulitis and the percentages of W3/25+ and OX6+ splenocytes. Interruption of the treatment resulted in a later onset of diabetes in a high percentage of animals within 41 days. These findings suggest that 15-DSP may temporarily reverse the pathogenic mechanisms leading to beta cell destruction and autoimmune diabetes in a well-known experimental model of human insulin-dependent diabetes mellitus.

    Description / Table of Contents: Zusammenfassung Die immunologischen Wirkungen von Cefodizim (CDZ), einem neuen Cephalosporin, wurden untersucht. In einerin vitro Studie mit Zellen, die aus dem Blut junger, gesunder Spender isoliert wurden, zeigte CDZ keine stimulierenden Wirkungen auf Lymphozyten, NK-Zell-Aktivität, IL-1 Produktion durch haftende mononukleäre Zellen, die Chemilumineszenz und Chemotaxis von polymorphkernigen neutrophilen Granulozyten (PMN). Ein geringer, statistisch nicht signifikanter Anstieg der PMN Phagozytose und des Phagozytose-Index wurde beobachtet. Bei drei Personen mit niedriger IL-1 Produktion in Ruhe konnte ein Anstieg derselben induziert werden. Im Rahmen einer kontrolliertenex vivo Studie erhielten 20 gesunde ältere Versuchspersonen, die aufgrund einer verminderten PMN Phagozytose ausgewählt worden waren, CDZ 2 × 1 g i.m. oder Plazebo über einen Zeitraum von acht Tagen. Die Funktion der PMN wurde vor Behandlungsbeginn und am Tag nach der letzten Dosis bestimmt. In der CDZ-Gruppe kam es zu einem signifikanten Anstieg der Phagozytose und des Phagozytose-Index, während in der Plazebo-Gruppe keine Veränderungen beobachtet wurden. Schlußfolgerung: CDZ konnte bei älteren gesunden Versuchspersonen eine verminderte Phagozytosetätigkeit der PMN wiederherstellen. Patienten mit gestörter PMN-Funktion, die einer antibiotischen Behandlung bedürfen, könnte diese Eigenschaft von CDZ zugute kommen.
    Notes: Summary The biological response modifying activities of cefodizime (CDZ), a new third-generation cephalosporin, were investigatedin vitro andex vivo. In vitro investigations using cells isolated from the blood of young healthy donors showed no stimulating activity of CDZ on peripheral blood lymphocytes, natural killer cell activity, IL-1 production by adherent mononuclear cells, PMN chemiluminescence or PMN chemotaxis. A slight but statistically insignificant increase in PMN phagocytosis and phagocytic index was observed in the same population. IL-1 production was increased in three subjects with low resting state values. In a controlledex vivo study, 20 health elderly subjects selected on the basis of depressed phagocytic function were treated with CDZ 1 g i.m. b.i.d. or placebo for eight days. PMN function was determined at baseline and on the day after the last dose. In the CDZ group a significant increase in both phagocytosis and phagocytic index was found, while there were no changes in the placebo group. In conclusion, CDZ restored depressed PMN phagocytic function in a population of elderly subjects. Patients with impaired PMN function who require antibiotic treatment may benefit from this activity of CDZ.
