    Notes: Summary Antihypertensive therapy influences kidney function by different mechanisms depending on the mode of action of the drug used. The GFR is improved by calcium entry blockers and ACE inhibitors, unaffected by vasodilators, α-blockers and centrally acting sympatholytics and impaired by β-blockers. The same is true for renal blood flow and is due to changes of renal vascular resistance. Renal sodium excretion is impaired mostly by vasodilators, by α-blockers, sympatholytics and β-blockers; in contrast, calcium entry blockers and ACE inhibitors acutely induce natriuresis. The RAAS is stimulated by vasodilators, unaffected by α-blockers and sympatholytics and suppressed by β-blockers. Plasma catecholamines are stimulated by vasodilators and suppressed by centrally acting sympatholytics and unaffected by the others. Induction of acute renal functional impairment is reported for ACE inhibitors under conditions of compromised renal perfusion pressure such as in renal artery stenosis. These data from the literature reviewed are supported by our own experimental data on sodium balance under different drugs and micropuncture data in experimental renal artery stenosis. To achieve effective antihypertensive treatment with a low profile of side effects, careful monitoring of renal function seems to be mandatory.

    Description / Table of Contents: Summary During reuse of formaldehyde sterilized Kiil-dialysers, red cell survival, measured by means of51Cr t/2, was significantly reduced (p〈0.001) in 16 patients with anti-N-like positive sera, when compared with 19 antibody negative control patients (Mean±SD: 16.5±2.7 versus 22.4±3.1 days.) In antibody negative patients (n=10) replacement of form-aldehyde sterilized dialysers by ethylene-oxide sterilized disposable dialysers resulted in a significant increase (p〈0.002) of51Cr t/2 (Mean±SD, days: Kiil-dialyser 16.3±1.9; disposable dialyser 20.3±3.5). This improvement took place, although antibody titres persisted during the51Cr-measurements and declined thereafter only slowly. In antibody negative patients (n=6) red cell survival did not increase, when formaldehyde as a sterilant was avoided. In antibody positive patients mean haematocrit rose significantly (p〈0.05), whereas in none of the antibody negative patients a definite change of haematocrit occurred. The data demonstrate, that formaldehyde sterilisation of dialysers may cause antibody-mediated haemolysis contributing to the extent of renal anaemia. This immunohaemolysis may be corrected, in spite of continuing antibody persistance, when formaldehyde exposure is totally avoided, or possibly when minimized.
    Notes: Zusammenfassung Während der Wiederverwendung Formaldehyd-sterilisierter Kiil-Dialysatoren war die mit51Cr bestimmte Erythrocytenüberlebenszeit bei 16 Patienten mit Anti-N-artigen Antikörpern significant (p〈0,001) kürzer als bei 19 Antikörper-negativen Kontrollpatienten (MW±SD: 16,5±2,7 bzw. 22,4±3,1 Tage). Bei Antikörper-positiven Patienten (n=10) führte das Umsetzen von Formaldehyd-sterilisierten Kiil-Dialysatoren auf Ethylenoxid-sterilisierte Einmaldialysatoren vergleichbarer Effektivität zu einem sofortigen, signifikanten (p〈0,002) Anstieg der Erythrocytenüberlebenszeit (MW±SD: 16,3±1,9 Tage, Kiil-Dialysator; 20,3±3,5 Tage Einmaldialysator). Die Antikörper-Titer blieben während der Messung der Erythrocytenüberlebenszeit unverändert, danach fielen sie im Verlauf von Monaten langsam ab. Bei Antikörper-negativen Kontrollpatienten (n=6) führte das Umsetzen von Formaldehyd-sterilisierten Kiil-Dialysatoren auf die Ethylenoxid-sterilisierten Einmaldialysatoren nicht zum Anstieg der Erythrocytenüberlebenszeit. Bei den Antikörper-positiven Patienten stieg der mittlere Hämatokritwert nach dem Umsetzen signifikant (p〈0,05) an, dagegen kam es nach dem Umsetzen bei keinem der Antikörper-negativen Patienten zu einer gerichteten Veränderung der Hämatokritwerte. Die Untersuchungen belegen, daß die Formaldehyd-Sterilisation von Dialysatoren zu einer Antikörper-vermittelten Hämolyse führen kann, die zum Ausmaß der renalen Anämie dieser Patienten beiträgt. Diese Immunhämolyse kann, auch bei Persistenz der Anti-N-artigen Antikörper, zumindest teilweise verhindert werden, wenn eine weitere Formaldehyd-Exposition des Patienten vermieden wird.

    Description / Table of Contents: Zusammenfassung Das Zusammentreffen von Nebennierenrinden- und Schilddrüseninsuffizienz wird in der Literatur als Schmidt-Syndrom bezeichnet. Bei 2/3 dieser Patienten findet man einen koexistenten Diabetes mellitus Typ I. Da in der Gruppe der Diabetiker das Auftreten von pluriglandulären Erkrankungen beschrieben ist, sollte ein Krankheitsprozeß mit auffälliger Adynamie, Erbrechen, Bauchschmerzen, Exiskkose und Hypotonie auch an das gleichzeitige Vorliegen eines M. Addison denken lassen. Zusätzlich ist das frühzeitige Erkennen einer beginnenden Addison-Krise sehr wichtig, da trotz Intensivmedizin dieses Krankheitsbild mit einer hohen Letalität behaftet ist.
    Notes: Summary The coexistance of thyroid- and adrenocortical insufficiency is known as Schmidt's syndrome. In two-thirds of these patients you find also diabetes mellitus. In the group of diabetic patients one sees pluriglandular endocrine dysfunction more often than in non-diabetic patients. Therefore, one should be aware of a coexisting Addision's disease in diabetic patients who are complaining of tireness, weakness, vomiting, abdominal pain, and circulatory disturbances. It is very important to detect this combination as early as possible, because the lethality of an Addisionian crisis is still high.
