    Description / Table of Contents: Summary Chronic uremia caused by diabetic glomerulopathy accounts for about 25 percent of new patients treated by maintenance hemodialysis. At the onset of glucose intolerance, insulin dependent diabetics have larger than normal kidneys, with a markedly increased glomerular filtration rate. During the subsequent 15 to 20 years of insulin use, glomerulosclerosis progresses silently, until a clinically overt nephrotic syndrome becomes evident. Thereafter, the clinical manifestations of nephropathy appear rapidly with an exponential decline in creatinine clearance to less than 5 ml/min within one to five years. Putting together a life plan for a nephrotic and azotemic diabetic involves awareness, and coordinated management of not only renal but extrarenal vasculopathic complications of diabetes, especially proliferative retinopathy. Carefully made preparations for hemodialysis and/or renal transplantation will increase chances for at least a short-term favorable outcome, which can now be anticipated in a growing proportion of patients.
    Notes: Zusammenfassung Eine diabetische Glomerulosklerose ist für ca. 25% der neu ins Hämodialyseprogramm aufzunehmenden Urämiepatienten verantwortlich. Zu Beginn ihrer Glukoseintoleranz zeigen insulinpflichtige Diabetiker eine erhöhte glomeruläre Filtrationsrate und übernormal große Nieren. Während der sich anschließenden Therapieperiode mit Insulin schreitet die Glomerulosklerose zunächst unmerklich fort, bis sich nach 15–20 Jahren ein nephrotisches Syndrom demaskiert. Innerhalb einer Zeitspanne von 5 Jahren kommt es sodann zu einer raschen Manifestation der Niereninsuffizienz mit einer exponentiall abnehmenden Kreatininclearance auf weniger als 5 ml/min. Der Therapieplan des nephrotischen Diabetikers mit Azotämie umfaßt neben der detaillierten Aufklärung des Patienten eine koordinierte Behandlung aller im Rahmen der diabetischen Grunderkrankung auftretenden renalen und extrarenalen Komplikationen, insbesondere der proliferativen Retinopathie. Sorgfältig getroffene Vorbereitungen für die Hämodialyse und/oder die Nierentransplantation erhöhen — zumindest für eine begrenzte Zeit — die Chancen auf eine verbesserte Lebensqualität.

    Notes: Summary The acute effects of i.v. disopyramide (1.5 mg/kg) on the hemodynamics of postischemic hearts were investigated in comparison to normal ventricles. Infusion (7 min) was started in rats 20 min after 3×4 min of global ischemia during the period of stable postischemic dysfunction. 15 minutes after disopyramide i.v. (vs. NaCl control data) the cardiac output was reduced to 82±4% (vs. 101±5%;p〈0.01) anddp/dt max to 77±5% (vs. 83±3%). The maximum isovolumic pressure generating capacity as load-independent index of myocardial contractility was reduced to 89±2% (vs. 95±2%;p〈0.05). In contrast to the results on postischemic myocardium no measureable change of the hemodynamics was detectable after the identical dose in normal animals without left ventricular dysfunction. Our results indicate an increased sensitivity of postischemic myocardium with modestly reduced contractile function to the hemodynamic effects of disopyramide, especially to the negative-inotropic effects.
