    Notes: Summary The severe and complicated course of a Legionella pneumonia in an 18-year-old female patient is reported. The serogroup 8 ofLegionella pneumophila was identified as the infecting agent for the first time in West Germany. The etiological diagnosis was confirmed by immunofluorescence, enzyme immunoassay, and immunoblot. We emphasize the importance of serological testing of allLegionella pneumophila serogroups available.

    Notes: Summary The pathogenesis of gluten-sensitive enteropathy is as yet unknown. According to one theory gluten may act as a lectin with toxic properties for the intestinal cells. We can now confirm this theory by laser nephelometric measurements and demonstrate the oligomannosyl specificity of this lectin-like protein gluten. Furthermore, we demonstrate the highly more intensive binding capacity of gluten for the glycoproteins of the immature crypt cells of the intestinal brush border compared to those from the mature villous zone. It is discussed that gluten-sensitive enteropathy is caused by a genetically determined defect-glycosylation of intestinal glycoproteins with the synthesis of more mannosylated glycoproteins.

    Notes: Summary The corn protein gluten causes the gluten-sensitive enteropathy in susceptible persons (HLA-antigens). The diagnosis is made on the basis of the morphological criteria of villous atrophy of the jejunal mucosa and the clinical observation that the malabsorption can be healed by a gluten-free diet. The disease, which occurs in children and adults, is a distinct entity. Life-long adherence to a gluten-free diet is difficult. Intentional or unintentional reintroduction of gluten often causes masked disease states. These are best classified on the basis of electron-microscopy study of the jejunal biopsy. We propose a new classification of the phases of remission. A group of diseases exist which are closely related to gluten-sensitive enteropathy. Frequently villous atrophy is detectable. However, the disease does not respond to a gluten-free diet. The pathophysiology of these diseases is at present unclear. Diseases involving autoimmune processes also appear to be associated with gluten-sensitive enteropathy. The common factor is probably an immuno-genetic defect. This is supported by the existence of common HLA-antigen constellations. Gluten has been characterised in vitro as a lectin with oligomannose specifity. This provides a new pathomechanism for the gluten induced enterocytic destruction.

    Description / Table of Contents: Summary The results of three different stimulation tests for ADH (17 hours thirst period, Carter-Robbins-test, osmotic diuresis) correlate well in the same patient. Because of this we propose a simplified procedure for the detection of failure to produce a concentrated urine. In most cases merely on the basis of a precisely executed thirst period test, one can either recognize an abnormality of concentration (highest urine osmolality less than 500 mOsm/kg), or exlude it (highest urine osmolality greater than 750 mOsm/kg). Only when the highest urine osmolality lies between 500 and 750 mOsm/kg after a 17 hour thirst must more painstaking tests (e.g. Carter-Robbins test) be employed to determine both the presence of and the degree of a failure to produce a concentrated urine. An injection of ADH can be used to differentiate between a deficiency of ADH and a defective response of the kidneys to ADH. Our investigations on hypophysectomized patients (n=29) showed that also in patients without the syndrome of polyuria-polydypsia (n=22), there was a significantly reduced capacity to concentrate urine during a 17 hour thirst period, as compared with normal people.
    Notes: Zusammenfassung Verschiedene, am gleichen Patienten durchgeführte Stimulationsteste für die ADH-Sekretion (17-Std.-Durstversuch, Carter-Robbins-Test, osmotische Diurese) zeigen eine ausgezeichnete Korrelation. Auf Grund dieser Ergebnisse werden Richtlinien zur möglichst einfachen Diagnostik einer Konzentrationsstörung vorgeschlagen. In den meisten Fällen kann allein schon auf Grund eines exakt durchgeführten Durstversuchs eine Konzentrationsstörung nachgewiesen (höchste Urinosmolalität 〈 500 mOsm/kg) bzw. ausgeschlossen (höchste Urinosmolalität 〉 750 mOsm/kg) werden. Lediglich bei einer höchsten Urinosmolalität im 17-Std.-Durstversuch zwischen 500 und 750 mOsm/kg müssen aufwendigere und den Patienten mehr belastende Tests (z. B. Carter-Robbins-Test) eingesetzt werden, um das Vorliegen bzw. den Grad einer Konzentrationsstörung endgültig diagnostizieren zu können. ADH-Injektionen dienen dabei zur Differenzierung zwischen einem ADH-Mangel und einer mangelhaften ADH-Ansprechbarkeit der Niere. Unsere Untersuchungen an hypophysektomierten Patienten (N=29) zeigen auch bei Patienten ohne polyurisch-polydiptisches Syndrom (N=22) eine gegenüber Normalpersonen signifikant eingeschränkte Konzentrationsleistung im 17-Std.-Durstversuch.

    Description / Table of Contents: Summary ACTH-contents of 1 ml specimens of human plasma were assayed by measurement of increases of corticosterone output in the adrenal vein of acutely hypophysectomized rats. This procedure is not sensitive enough to measure normal ACTH-levels acurately, neither when blood was drawn from the bulbus cranialis venae jugularis, nor from the vena cubitalis. In patients having pathologically elevated ACTH-levels, the ACTH-content of plasma is significantly higher in the bulbus cranialis venae jugularis than in peripheral venous blood. An equation is presented formulating the relation of peripheral ACTH-levels, differences of ACTH-levels between bulbus cranialis venae jugularis and vena cubitalis, and of the biological halflife of endogenous ACTH. On the basis of the results of the determinations of socalled normal ACTH-levels it can be concluded, that the biological halflife of endogenous ACTH is longer than 4 min. From the data of patients with elevated ACTH-levels a halflife of approximately 40 min and a mean ACTH-secretion of approx. 100 units per day could be calculated.
    Notes: Zusammenfassung Der Anstieg der Corticosteroninkretion in das Nebennierenvenenblut frisch hypophysektomierter Ratten diente zur Bestimmung von ACTH-Spiegeln in 1 ml nativen, menschlichen Plasma. Normale ACTH-Plasmaspiegel sind sowohl bei Punktion der Vena cubitalis als auch des Bulbus cranialis venae jugularis durch diese Methode nicht oder nur ungenau zu erfassen. Bei Patienten mit pathologisch erhöhten ACTH-Spiegeln in der Vena cubitalis sind die ACTH-Spiegel im Bulbus cranialis venae jugularis signifikant höher. Es ließ sich eine Beziehung zwischen ACTH-Spiegel in der Peripherie (Vena cubitalis), Differenz der ACTH-Spiegel zwischen Bulbus cranialis venae jugularis und Vena cubitalis und biologischer Halbwertszeit von endogenem ACTH aufstellen. Nach den Ergebnissen der Bestimmung von ACTH-Spiegeln bei Nebennierengesunden läßt sich folgern, daß die biologische Halbwertszeit von endogenem ACTH größer als 4 min sein muß. Bei Patienten mit erhöhten ACTH-Spiegeln ließ sich die biologische Halbwertszeit von endogenem ACTH größenordnungsmäßig mit ca. 40 min berechnen. Bei diesen Patienten betrug die mittlere tägliche ACTH-Inkretion ca. 100 E.
