    Notes: Summary In the present study, 8 Type 1 diabetic patients with normal creatinine clearance and 8 matched controls were examined. Tamm Horsfall glycoprotein was isolated with the NaCl precipitation procedure. Its purity was checked by gelelectrophoresis, immunodiffusion and isoelectric focussing. Tamm Horsfall glycoprotein of diabetic patients had higher glucose (p〈0.05) and lower N-acetylneuraminic acid content (p〈0.01) than controls. 14C-furosemide binding by Tamm Horsfall glycoprotein was examined using an Amicon ultrafiltration system at 0 °C. In nominally sodium-free medium, furosemide binding by Tamm Horsfall glycoprotein was significantly (p〈0.01) higher in diabetic patients than in matched controls. The increment of binding capacity with sodium was similar in controls and diabetic patients so that maximal binding capacity in a NaCl system was 1.7±0.3 in controls and 3.64±0.5 in diabetic patients (p〈0.025). Half maximal furosemide binding by Tamm Horsfall glycoprotein occured at 1.4±0.2mmol Na/l in controls and 0.52±0.12 in diabetic patients (p〈0.01). Abnormal radiofurosemide binding of Tamm Horsfall glycoprotein of diabetic patients may be the consequence of abnormal postribosomal modification of the glycoprotein which is synthesized in an insulin- and glucose-sensitive nephron segment.

    Notes: Summary The respective rôles of arterial blood pressure and metabolic control in different stages of diabetic nephropathy were analyzed retrospectively in 52 sequentially-followed Type 1 (insulin-dependent) diabetic patients. A negative correlation was found between median post-prandial blood glucose and median duration of diabetes until onset of persistent proteinuria (p〈0.01). Systolic blood pressure was higher in patients who subsequently developed persistent proteinuria than those who did not (140 versus 121 mmHg; p〈0.05), but duration of the interval until onset of persistent proteinuria was not related to blood pressure. After onset of persistent proteinuria, hypertensive diabetic patients developed elevated serum creatinine concentrations more frequently than normotensive diabetic patients (67% versus 14%, p〈0.05). In these patients, the delay until elevation of serum creatinine concentration was negatively correlated with blood glucose (p〈0.01). Once serum creatinine was raised, decay of renal function occurred faster in patients with persistent than intermittent hypertension (p〈0.05). No effect of metabolic control was demonstrable at this stage of nephropathy. It is concluded that metabolic control determines the early course of diabetic nephropathy, whereas blood pressure is more important in advanced stages of nephropathy.

    Notes: Summary Increased oxidative stress and subsequent activation of the transcription factor NF-kB has been linked to the development of late diabetic complications. To determine whether oxidative stress dependent NF-kB activation is evident in patients with diabetic nephropathy we used an Electrophoretic Mobility Shift Assay based semiquantitative detection system which enabled us to determine NF-kB activation in ex vivo isolated peripheral blood mononuclear cells. We examined 33 patients with diabetes mellitus (Type I and Type II). Patients with diabetic nephropathy showed higher NF-kB binding activity in Electrophoretic Mobility Shift Assays and stronger immunohistological staining for activated NF-kBp65 than patients without renal complications. NF-kB binding activity correlated with the degree of albuminuria (r = 0.316) and with thrombomodulin plasma concentrations (r = 0.33), indicative for albuminuria associated endothelial dysfunction. In a 3 day intervention study in which 600 mg of the antioxidant thioctic acid (α-lipoic acid) per day were given to nine patients with diabetic nephropathy oxidative stress in plasma samples was decreased by 48 % and NF-kB binding activity in ex vivo isolated peripheral blood mononuclear cells by 38 %.

    Notes: Summary In insulin-dependent diabetes mellitus (IDDM) elevated exchangeable sodium (Na) levels are found even in the absence of hypertension, but it is not known whether this is associated with increased sensitivity of blood pressure to sodium level. To clarify this issue we compared 30 patients with IDDM (19 without and 11 with microalbuminuria, i.e. more than 30 mg albumin/day) and 30 control subjects matched for age, gender and body mass index. The subjects were studied on the 4th day of a low-salt diet (20 mmol/day) under in-patient conditions and were subsequently changed to the same diet with a high-salt supplement, yielding a total daily intake of 220 mmol Na/day. Circadian blood pressure, plasma renin activity (PRA), plasma atrial natriuretic factor (p-ANF), plasma cyclic guanosine 5′-phosphate (p-cGMP) and urinary albumin were measured. The proportion of salt-sensitive subjects, i.e. showing increment of mean arterial pressure ≥ 3 mmHg on high-salt diet, was 43% in diabetic patients (50% of diabetic patients with and 37% without microalbuminuria) and 17% in control subjects (p〈0.05). Lying and standing PRA levels on low- or high-salt diet were significantly lower in diabetic patients than in control subjects. Salt-sensitive diabetic patients had significantly higher lying ANF on high-salt (38.7±4.2 pmol/l vs 20.1±2.3 pmol/l, p〈0.005) than on low-salt diet. The results suggest that (i) the prevalence of sodium sensitivity is high in IDDM (ii) sodium sensitivity is found even in the absence of nephropathy as indicated by albuminuria.

    Notes: Summary The objective of this study was to examine diabetic patients at the time of admission to maintenance haemodialysis and to follow them for 36 months in order to define predictors of cardiovascular and non-cardiovascular death. This prospective study comprised all consecutive diabetic patients admitted to 28 German dialysis centres between January 1985 and October 1987; 196 patients were examined, 67 Type 1 (insulin-dependent) diabetic (43 male, 24 female; median age 49 years, range 22–73) and 129 Type 2 (non-insulin-dependent) diabetic patients (54 male, 75 female; 64 years, range 37–82). Outcome measures were death, i.e. myocardial infarction, sudden death, cardiac death of other causes, stroke and noncardiovascular death. Actuarial survival 36 months after the beginning of dialysis was similar in Type 1 (40%) and Type 2 diabetic patients (43%) despite the age difference. Causes of death were myocardial infarction (18%), sudden death (18%), other cardiac causes (18%); stroke (6%); septicaemia (17%) mostly originating from diabetic foot problems; and interruption of therapy. Survival rates and the proportion dying from cardiac causes were similar in patients with diabetic nephropathy or with other primary chronic renal disease and coincidental diabetes. On dialysis, de novo amaurosis or de novo amputation was not observed in any patient. The strongest predictor of myocardial infarction or sudden death was serum lipids on admission. Duration of hypertension, blood pressure at the time of admission to dialysis, left ventricular hypertrophy or end-diastolic diameter by echocardiography, Sokolow index and average predialysis blood pressure, smoking, interdialytic weight gain and type of dialysis were not predictive of cardiovascular death or death by all causes. Patients with myocardial infarction were more frequently male (70% of myocardial infarction), tended to be younger, more frequently had a history of myocardial infarction (relative risk 3.0) and more frequently had angina pectoris, proliferative retinopathy (relative risk 2.8) or somatosensory polyneuropathy (relative risk 3.0). Patients dying from myocardial infarction or other cardiac causes had more frequent episodes of intradialytic hypotension and tended to be less frequently on beta blocker treatment. We conclude that cardiac death accounts for most fatalities of diabetic patients on dialysis. Some, but not all, classic risk factors are predictive of cardiac death.

    Description / Table of Contents: Zusammenfassung Die Erhöhung der Dialysat-Magnesium-Konzentration von 1,5 mval/l auf 2,5 mval/l bei Verwendung einer Dialysat-Calcium-Konzentration von 3,5 mval/l führte zu keiner signifikanten Reduktion der radioimmunologisch gemessenen Serum-Parathormonspiegel. Bei ausreichend hohen Dialysat-Calcium-Konzentrationen bewirkt somit die Erhöhung der Dialysat-Magnesiumspiegel keine weitere meßbare Reduktion der PTH-Ausschüttung.
    Notes: Summary An inerease of dialysate magnesium concentration from 1.5 mval/l to 2.5 mval/l did not reduce significantly i PTH levels in haemodialysed patients, dialysed against 3.5 mEq Ca/l in the dialysate. Thus, when sufficiently high Ca concentrations in the dialysate are used, no further reduction of serum PTH levels is seen by elevating Mg in dialysate.

    Description / Table of Contents: Summary Plasma dopamin-β-hydroxylase (DBH) was studied in 70 healthy control persons and in 37 hemodialysed patients. Basal DBH in controls corresponded to 50.0±29.3 IU. There was no significant difference between males (53.9±33.8 IU) and females (47.4±25 IU); no correlation could be found between age and plasma DBH. In hemodialysed patients basal DBH levels were significantly (p〈0.01) decreased (32.5±17.6 IU), suggesting lowered sympathetic activity and/or abnormalities in release, distribution space, or metabolism of DBH. During hemodialysis plasma DBH activity rose during ultrafiltration. This finding indicates a directionally appropriate sympathetic reflex response to volume depletion in dialysed patients.
    Notes: Zusammenfassung Die Plasma Dopamin-β-Hydroxylase-Aktivität (DBH) wurde bei 70 gesunden Kontrollpersonen und 37 Hämodialysepatienten untersucht. Bei Kontrollpersonen wurde eine basale DBH-Aktivität von 50,0±29,3 IE gefunden. Es bestand kein signifikanter Unterschied zwischen Männern (53,9±33,8 IE) und Frauen (47,4±25 IE). Es wurde keine Korrelation zwischen Lebensalter und basaler DBH-Aktivität gefunden. Die basale DBH-Aktivität war bei Hämodialysepatienten signifikant (p〈0,01) vermindert (32,5±17,6 IE); der Befund ist vereinbar mit verminderter Sympathikusaktivität und/oder Störungen der Freisetzung, des Verteilungsvolumens oder des Abbaues von DBH. Unter Hämodialyse stieg die Plasma DBH-Aktivität während Ultrafiltration an. Dieser Befund belegt eine Aktivierung sympathischer Reflexe durch Volumendepletion bei hämodialysierten Patienten.

    Description / Table of Contents: Zusammensetzung Die kritische und lebenswichtige Rolle von anorganischem Phosphat ist in der Veterinärmedizin und der tierexperimentellen Forschung seit Jahrzehnten bekannt. Das Syndrom der Phosphat-Depletion fand in der Klinik jedoch erst seit kurzem stärkere Beachtung. Eine Hypophosphatämie wird bei folgenden Krankheitsbildern gehäuft beobachtet: chronischer Alkoholismus, Erholungsphase der diabetischen Ketoazidose, parenterale Ernährung mit Phosphat-freien Lösungen, schwere respiratorische Alkalose und Fruktose-Infusion. Die Organfunktionsstörungen bei Hypophosphatämie sind auf die Verarmung des Zytoplasmas an anorganischem Phosphat zurückzuführen. Eine derartige Phosphat-Verarmung kann (1) durch negative Phosphat-Bilanz des Gesamtorganismus als Folge renaler oder intestinaler Phosphat-Verluste oder (2) ohne negative äußere Phosphat-Bilanz durch Verschiebung von Phosphat aus dem extra- in den intrazellulären Raum auftreten. Die Phosphat-Depletion beeinträchtigt im Prinzip die Funktion aller Organe. Klinisch stehen bei der akuten Phosphat-Depletion Funktionsstörungen der Skelettmuskulatur (Rhabdomyolyse mit myoglobinurischem akutem Nierenversagen), Herzmuskulatur (akute Herzinsuffizienz) und des hämatologischen Systems (Hämolyse, gestörte Leukozyten- und Thrombozytenfunktion) im Vordergrund, während bei chronischer Phosphat-Depletion Skelettstörungen (Osteomalazie) vorherrschen. Die Organfunktionsstörungen sind wahrscheinlich auf verminderte Synthese von ATP und anderen organischen Phosphat-Metaboliten zurückzuführen. Verminderte 2,3-DPG-Spiegel in Erythrozyten und die hierdurch bedingte Hypoxie sind eine weitere mögliche Ursache von Organfunktionsstörungen.
    Notes: Summary The essential and critical role of inorganic phosphate has been known in veterinary medicine and experimental research on animals for decades. However, only recently has the phosphate depletion syndrome found widespread attention by clinicians. Hypophosphatemia is usually observed in the following clinical situations: chronic alcoholism, recovery phase of diabetic ketoacidosis, administration of phosphate-free solutions in parenteral nutrition, severe respiratory alkalosis, and infusion of fructose. Disturbed organ function in hypophosphatemia is the result of a depletion of inorganic phosphate in the cytoplasm of somatic cells. Such phosphate depletion may be due to either of the following mechanisms or a combination of both. (1) Negative external phosphate balance resulting from phosphate loss in urine or feces or (2) translocation of phosphate from the extracellular into the intracellular space with or without concomitant negative external phosphate balance. In principle, phosphate depletion interferes with the function of all somatic cells. In acute phosphate depletion, the clinically most important disturbances are observed in striated muscle (rhabdomyolysis with myoglobinuric acute renal failure), heart muscle (acute heart failure), and hematological systems (hemolysis, disturbed leukocyte and thrombocyte functions). In contrast, in chronic phosphate depletion skeletal abnormalities (osteomalacia) predominate. Organ disturbances are thought to result from diminished synthesis of ATP and other organic phosphate esters and/or from hypoxia secondary to changes in erythrocyte 2,3-DPG.

    Description / Table of Contents: Summary The risk of thromboembolic complications in patients with the nephrotic syndrome (NS) is higher than in any other condition encountered in internal medicine. Such thromboembolic complications comprise venous thromboses (calf, thigh, renal vein) with or without pulmonary embolism and arterial thromboses (coronary thromboses, cerebral artery thromboses, peripheral arterial thromboses). Several defects of the plasmatic coagulation system, fibrinolysis and platelet function had been recognized in the nephrotic syndrome. Increased hepatic synthesis causes a rise of coagulation factors, I, II, VII, VIII, X and increased renal loss causes lowering of the plasma concentration of antithrombin III concentration. There is little evidence for DIC. Plasminogen concentration is diminished, whereas total antiplasmin activity is increased. Low alpha-1-antitrypsin concentration secondary to renal loss is outweighed by increased concentrations of other inhibitors especially alpha-2-macroglobulin and alpha-2-antiplasmin. The common presence of material in the urine reacting as fibrin degradation products with passive hemagglutination techniques appears to be proteolytically degraded fibrinogen excreted as a result of non-selective glomerular proteinuria. Platelet counts are normal or slightly elevated and platelet survival time is slightly, decreased. Definite abnormalities of spontaneous aggregation and ADP- or collagen-induced aggregation are demonstrable. Furthermore, arachidonic acid induced platelet aggregation and malondialdehyde formation by platelets of NS patients are increased. Addition of albumin to platelets of NS patients normalises platelet aggregation. This finding points to some acquired defect of platelet function. There is a clearcut relation between the risk of thromboembolic complications and plasma albumin concentration: thromboses are particularly frequent at plasma albumin concentrations below 2 g/dl. Consequently, it is suggested, that NS patients with plasma albumin 〈2 g/dl should be given platelet aggregation inhibitors prophylactically. If there is a history of venous thrombosis, long term anticoagulation with dicumarol is indicated.
    Notes: Zusammenfassung Das nephrotische Syndrom (NS) ist die intern-medizinische Grunderkrankung mit dem höchsten Risiko an venösen (Unterschenkelvenen-Thrombose, Beckenvenen-Thrombose, Cava- und Nierenvenen-Thrombose ggf. mit Lungenembolie) und arteriellen (Herzinfarkt, Cerebralarterien-Thrombose, periphere arterielle Thrombose) thromboembolischen Komplikationen. Aufgrund neuerer hämostaseologischer Untersuchungen können beim NS Defekte des plasmatischen Gerinnungssystems, der Fibrinolyse und der Plättchenfunktion festgestellt werden. Infolge der globalen Synthesesteigerung hepatischer Exportproteine ist die Plasmakonzentration der meisten Gerinnungsfaktoren (speziell Faktor I, II, VII, VIII und X) gesteigert; infolge erhöhten renalen Verlustes ist die Plasma-Konzentration des Inhibitors Antithrombin III vermindert. Die Änderung der Plasma-Konzentration ist das Ergebnis gesteigerter hepatischer Synthese und/oder renalen Verlustes im Rahmen der Proteinurie. Hinweise für eine intravasale Gerinnung fanden sich — im Gegensatz zu Angaben der Literatur — in eigenen Untersuchungen nur selten. Die Plasminogenkonzentration ist vermindert, während die Gesamt-Aktivität der Plasmin-Inhibitoren erhöht ist. Allerdings ist die Alpha-1-Antitrypsin-Konzentration wegen gesteigerten renalen Verlustes meist vermindert, was jedoch durch erhöhte Konzentration anderer Inhibitioren, speziell Alpha-2-Makroglobulin und Alpha-2-Antiplasmin kompensiert wird. Obwohl im Urin Material gefunden wird, welches in der passiven Hämagglutination wie Fibrinspaltprodukte reagiert, zeigten neuere Untersuchungen, daß dieses Material Fibrinogensplatprodukte darstellt (nicht selektive glomeruläre Proteinurie) und nicht Fibrinspaltprodukte infolge lokaler oder systemischer Fibrinolyse. Die Plättchenzahlen sind normal oder mäßig erhöht und die Plättchen-Überlebenszeit ist geringfügig verkürzt. Hingegen lassen sich deutliche Abweichungen der Spontanaggregation sowie der ADP- und Kollagen-induzierten Aggregation nachweisen. Desgleichen ist die Plättchen-Aggregation durch Arachidonsäure gesteigert und die Malondialdehyd-Bildung erhöht. Die Plättchen nephrotischer Patienten weisen nach Zugabe von Albumin ein normales Aggregationsverhalten auf, was auf eine erworbene Funktionsstörung hinweist. Das wichtige Gebiet der Plättchenfunktion bei NS ist derzeit noch wenig erforscht. Aus den klinischen und hämostaseologischen Befunden wird die Forderung abgeleitet, bei Patienten mit nephrotischem Syndrom in jedem Falle Plättchen-Aggregationshemmer zu verabfolgen; bei Vorliegen venöser Thrombosen ist eine Langzeit-Antikoagulation mit Marcumar anzuraten.

    Description / Table of Contents: Summary In 40 patients with non-metastasising (n=31) and metastasising (n=9) renal cell carcinoma, evidence of Stauffer's syndrome (increase in alkaline serum phosphatase and prolongation of prothrombin time) was found in 18 patients. Prolongation of prothrombin time was not due to depletion of vitamin K-dependent coagulation factors or manifest fibrinolysis, but due to the presence of circulating fibrinogen fibrinmonomer-FDP complexes. Ethanol gelation test was found to be positive in 28/40 subjects and soluble fibrin monomer complexes were increased in 38/40 patients. The resulting disturbance of fibrinogen-fibrin conversion was reflected by an increase in thrombin coagulase time and reptilase time. These findings suggests a state of latent compensated intravascular coagulation (presumably triggered within the vascular tumor). For diagnostic purposes the most sensitive indicator is thrombin coagulase time. Thrombin coagulase time normalised after tumor resection and was positive in patients with recurrent metastases. The increase in alkaline serum phosphatase was due to an increase in the hepatic isoenzyme. Such an increase was much more common than the elevation of total alkaline serum phosphatase. Regan's isoenzyme was only found in 1 subject. In parallel, gamma-GT was elevated in 24 patients. The study shows that Stauffer's syndrome occurs more frequently than commonly assumed when thrombin coagulase time, gamma-GT and the hepatic isoenzyme of alkaline serum phosphatase are determined in patients with renal cell carcinoma. DIC and low grade fibrinolysis may account for the coagulation abnormalities of the syndrome.
    Notes: Zusammenfassung Ein Stauffer-Syndrom (erhöhte alkalische Phosphatase und verlängerte Prothrombinzeit) wurde bei 18 von 40 Hypernephrom-Patienten gefunden. Es konnte gezeigt werden, daß die verlängerte Prothrombinzeit nicht auf eine Verminderung Vitamin K-abhängiger Gerinnungsfaktoren, sondern auf zirkulierende Fibrinogen-Fibrinomer-Fibrinspaltproduktkomplexe zurückzuführen ist. Der Alkoholtest nach Godal war bei 28 von 48 Patienten positiv und erhöhte Mengen an zirkulierenden Fibrinmonomeren wurden bei 38 von 40 Patienten gefunden. Eine gesteigerte Fibrinolyse ließ sich in 19 von 40 Patienten nachweisen. Die Verlängerung der Thrombinkoagulase-und Reptilasezeit wird auf die zirkulierenden Fibrinmonomer-Fibrinspaltproduktkomplexe zurückgeführt, die die gestörte Umwandlung von Fibrinogen in Fibrin verursachen. Die vorliegenden Befunde sprechen für eine latente kompensierte intravasale Verbrauchskoagulopathie, die wahrscheinlich innerhalb des gefäßreichen Tumors ausgelöst wird. Als empfindlicher Indikator für diagnostische Zwecke erwies sich die Thrombinkoagulasezeit. Die Thrombinkoagulasezeit normalisierte sich nach chirurgischer Entfernung des Tumors und wurde nach Auftreten von Metastasen wieder pathologisch. Die Erhöhung der alkalischen Phosphatase war in der Regel nur auf einen Anstieg des hepatischen Isoenzyms zurückzuführen. Zum Nachweis des Stauffer-Syndroms erwiesen sich das hepatische Isoenzym der alkalischen Phosphatase und die Gamma-GT empfindlicher als die Gesamt-alkalische Phosphatase.
