    Description / Table of Contents: Summary The immunologic status of patients with Hodgkin's diesease is characterized by a depression of delayed-type hypersensitivity. The defect of cellular immunity correlates with the activity of the disease and is demonstrated by cutaneous anergy to various bacterial and fungal antigens, by inability to acquire active sensitization with the contact allergens DNCB and DNFB, and by delayed homograft rejection. Lymphocyte counts in peripheral blood, lymphocyte transformation in vitro, cytotoxicity of lymphocytes, and the reactivity of lymphocytes following lymphocyte transfer are reduced. These changes indicate that the number or the functional capacity of T lymphocytes responsible for cellular immunity is reduced. Humoral immunity seems to be rather well preserved during the early stage of Hodgkin's disease. However, during terminal stages, the ability to form humoral antibodies may be impaired in some cases, as shown by a decreased serum concentration of IgM, a depressed primary response and a reduced duration or even a total failure of antibody production.
    Notes: Zusammenfassung Die immunpathologischen Veränderungen bei der Lymphogranulomatose sind vorwiegend durch eine Verminderung der Allergie vom Spättyp charakterisiert. Die Beeinträchtigung des zellulären Immunsystems manifestiert sich bereits in den Frühstadien der Erkrankung, nimmt jedoch in späteren Krankheitsphasen an Intensität und Häufigkeit zu. Sie korreliert mit der Aktivität des Krankheitsprozesses und äußert sich in negativen Hauttests gegen verschiedene Bakterien-und Pilzantigene sowie gegen die Kontaktallergene DNCB und DNFB und in einer verzögerten Transplantatabstoßung. Ferner sind eine Lymphozytopenie im perppheren Blut, eine herabgesetzte Lymphozytentransformation in vitro, eine verminderte Zytotoxizität der Lymphozyten und eine pathologische Lymphozyten-Transfer-Reaktion nachweisbar. Diese Veränderungen deuten darauf hin, daß entweder die Zahl oder die funktionelle Kapazität der für die zelluläre Immunität verantwortlichen T-Lymphozyten vermindert ist. Die Allergie vom Soforttyp scheint zumindest im Anfangsstadium der Erkrankung weitgehend erhalten zu sein. Auf eine mögliche Beeinträchtigung des humoralen Immunsystems deuten jedoch die verschiedentlich, vor allem in späteren Stadien nachgewiesene Reduktion der Serumkonzentration von IgM, die Verminderung der Primärreaktion, die mangelhafte Aufrechterhaltung oder das völlige Fehlen der Antikörper-Synthese hin.

    Description / Table of Contents: Summary A decreased activity of both DPNH- and TPNH-Glutathione-Oxido-Reductase (GSSG-Reductase) was found in the erythrocytes of a 16-year-old boy suffering from congenital non-spherocytic haemolytic anaemia. The optimal pH, the inhibition by GSSG and the Michaelis-Menten constants of both enzymes were found to be normal in comparison with controls. A diminished level of the normal enzyme protein rather than alteration of the protein configuration is discussed as a factor in the development of this type of anaemia.
    Notes: Zusammenfassung In den Erythrocyten eines 16jährigen Jungen mit einer angeborenen nichtsphärocytären hämolytischen Anämie wurde eine Aktivitätsminderung der DPNH- und TPNH-abhängigen Glutathionreduktase festgestellt. Da sich die pH-Optima, die Substrathemmung und die Michaelis-Menten-Konstanten beider Enzyme nicht von den Werten eines Normalkollektivs unterschieden, wird als Ursache der Erkrankung der Mangel eines normal strukturierten Enzymproteins und nicht das Vorliegen eines pathologischen Genproduktes diskutiert.

    Notes: Summary A strong correlation exists between the presence of an in vitro plasma coagulation inhibitor, named “lupus anticoagulant”, and a clinical syndrome of recurrent arterial and venous thromboses, neurological abnormalities, repeated obstetrical complications, thrombocytopenia, a biologic false-positive serological test for syphilis, and a variety of rarer manifestations. This syndrome has predominantly been observed in patients with autoimmune diseases, but it may be of similar importance in association with monoclonal gammopathies. As an introduction to a detailed analysis of ten observations which will also be published in this journal, this article reviews the clinical findings, the proposed pathogenetic mechanisms and the approaches to management of the lupus anticoagulant associated syndrome.

    Notes: Summary The clinical and laboratory findings in seven female patients with primary autoimmune diseases, one female patient with lymphoplasmacytoid (LP) immunocytoma and IgM paraproteinemia, and two male patients with multiple myeloma are described. The common denominator in all patients was a lupus anticoagulant or a closely related coagulation disorder. Recurrent thrombosis was observed in six patients with autoimmune diseases and in two patients with malignant monoclonal gammopathies. Other clinical manifestations included cerebral disorders (four patients with autoimmune disease/two patients with monoclonal gammopathy), repeated obstetric complications (6/1), asymptomatic valvular heart disease (6/1), renal dysfunction (6/2), hepatic involvement (2/2), and arthropathy (2/0). Laboratory investigations revealed a biologic false-positive serological test for syphilis in six patients with autoimmune disease and one with monoclonal gammopathy, antinuclear antibodies (4/0), antibodies against DNA (4/1), and a positive direct Coombs test (3/1) which was accompanied by hemolytic anemia in two patients (1/1). Additionally slight leucocytopenia (2/1) and thrombocytopenia (6/2) were observed; abnormal bleeding was only seen in one patient with severe thrombocytopenia. Other complications characteristic of LP immunocytoma or multiple myeloma were missing. The obvious similarities between the patients with autoimmune diseases and the patients with malignant monoclonal gammopathies suggest analogous pathogenetic mechanisms. Since the clinical syndrome associated with the lupus anticoagulant in patients with autoimmune disorders has been proposed to arise from the action of autoantibodies against phospholipids, it is attractive to hypothesize that the findings in the patients with malignant diseases were caused by an autoantibody activity of the monoclonal immunoglobulin. This assumption is substantiated by the observation that in one patient the paraprotein level correlated with the prolongation of the coagulation times and the severeness of the clinical perturbations. Although paraproteins mimicking the laboratory alterations of the lupus anticoagulant have been reported before, the corresponding clinical features have not yet been described in malignant monoclonal gammopathies. The syndrome may be juxtaposed to other systemic disorders complicating paraproteinemias, and is possibly more frequent than is as yet known.

    Description / Table of Contents: Summary A case of a 16-year-old boy with a congenital non-spherocytic haemolytic anaemia is reported whose erythrocytes were deficient in both DPNH- and TPNH-Glutathione-Oxido-Reductase (GSSG-Reductase). In the erythrocytes of one of his brothers with no signs of haemolytic anaemia we found a smaller decrease of the DPNH-GSSG-Reductase, whereas two healthy brothers demonstrated a normal DPNH, GSSG-Reductase. The TPNH-GSSG-Reductase was decreased in all brothers. Among the examined family members the patient showed the most extensive decrease of the DPNH-GSSG-Reductase. It is suggested that development of this particular type of haemolytic anaemia is determined by the degree of DPNH-GSSG-Reductase deficiency.
    Notes: Zusammenfassung In den Erythrocyten eines 16jährigen Jungen mit einer angeborenen nichtsphärocytären hämolytischen Anämie wurde eine Aktivitätsminderung der DPNH- und TPNH-abhängigen Glutathionreduktase festgestellt. Drei klinisch gesunde Brüder zeigten ebenfalls eine Aktivitätsminderung der TPNH-abhängigen Glutathionreduktase, während nur bei einem dieser Geschwister gleichzeitig ein Mangel an DPNH-abhängiger Glutathionreduktase bestand. Da die Aktivitätsminderung der DPNH-abhängigen Glutathionreduktase bei dem Patienten am stärksten war, wird angenommen, daß das Ausmaß dieses Enzymdefektes für das Auftreten der hämolytischen Anämie von Bedeutung ist.

    Notes: Summary Among the substances causing an unspecific stimulation of lymphocytes in vitro pokeweed mitogen (PWM), a glycoprotein isolated from pokeweed (Phytolacca americana L.), is of special interest. Studies performed at the light and electron microscope level have shown the production in vitro by PWM of large phytohemagglutinin (PHA) -like blasts and of a unique intermediate sized cell type exhibiting a well developed rough-surfaced endoplasmic reticulum and ribosomal aggregates. These plasmacytic cells have also been observed in the peripheral blood of humans who sustained systemic exposure to pokeberries. Further studies regarding the functional properties of these cells are required to determine whether or not PWM is able totransform lymphocytes into true plasma cells in vitro and in vivo.

    Notes: Zusammenfassung 1. Durch wiederholte Ultrazentrifugation von beschleunigt senkenden Seren lassen sich Agglomerine in den höhermolekularen Serumproteinanteilen anreichern. 2. Die Heterogenität der Agglomerine wird dadurch weiter belegt, daß zur 50% igen Blockung von beschleunigt senkenden Plasmen mit gleicher Senkungsaktivität unterschiedliche Mengen des Senkungsblockers Phenylbutazon benötigt werden. 3. Bei der Prüfung der Senkungsaktivität von gereinigten Plasmaproteinen zeigte sich, daß Haptoglobin, Fibrinogen und Coeruloplasmin zu den Agglomerinen gehören, da diese Plasmaproteine zur beschleunigten Senkung von Humanerythrocyten führen. Präalbumin, Albumin, saures α1-Glykoproteid und Transferrin besitzen dagegen in vergleichbarer Konzentration keine Senkungsaktivität. 4. In Dextran-Lösungen kommt es in Abhängigkeit vom Molekulargewicht der Dextrane zu einer beschleunigten Senkung von Humanerythrocyten. 5. Das Linearprotein Myosin bewirkt ebenfalls eine beschleunigte Senkung von Humanerythrocyten. 6. Poly-l-Aminosäuren sind schon in sehr geringen Konzentrationen senkungsaktiv. In höheren Konzentrationen führen sie zur Agglutination. 7. Die Ergebnisse werden in ihrer Bedeutung für das Verständnis der Blutkörperchensenkung diskutiert.

    Notes: The authors analysed the effect of protein kinase A (PKA) activation on the protein synthesis and secretion in the T-helper 2 cell line D10.G4.1 (D10) using an assay that allows the detection of almost all secreted proteins of a cell. IL-4 and IL-10 were quantified. Three groups of secretory products could be defined. The T-cell receptor (TCR)-induced production of the first group (A) of proteins including IL-4 was enhanced by low concentrations of PKA activators. At higher concentrations the enhancement was less marked. The synthesis and secretion of a second group (B) of proteins including IL-10 remained unaffected. The production of a third group (C) of proteins was inhibited in a concentration-dependent manner. Biochemical analysis revealed a block of phospholipase C γ (PLCγ) activity by PKA activators. When D10 cells were stimulated by a phorbol ester plus calcium ionophore the production of group A proteins was enhanced almost fourfold, whereas production of group B proteins was unaffected by PKA activation. This effect was observed at all concentrations of various PKA activators tested. The secretion of group C proteins was no longer inhibited. The same results were obtained when analysing IL-4 and IL-10 m-RNA by Northern blotting. The data demonstrate a lymphokine specific mode of action on a single cell basis. Furthermore, it suggests that the inhibitory action of PKA in D10 cells is due partly to blocking of PLCγ activity.
