    Notes: Summary Among a total of 2147 patients admitted to our hospital for acute myocardial infarction between 1978 and 1987, three young patients aged 24, 29, and 39 years had previously been treated for Hodgkin's disease. Staging laparotomy, including splenectomy, had been performed in all three patients. Two patients had both mediastinal irradiation (21 and 27 months before infarction) and chemotherapy. In the first patient, postmortem histologic examination of the coronary arteries revealed fibrotic changes, which were probably induced by radiotherapy. In our second patient, myocardial infarction developed 5 days after vinblastine treatment; early angiography showed thrombotic occlusion of the proximal right coronary artery, which was recanalized using the diagnostic Sones catheter. Subsequent angiography revealed normal coronary arteries. This is, to our knowledge, the first case of documented coronary artery thrombosis after treatment with vinca-alkaloids. In our third patient, neither mediastinal irradiation nor chemotherapy had been performed prior to myocardial infarction. However, a marked increase in platelet counts following splenectomy was observed in this patient. The role of radiotherapy, chemotherapy, and splenectomy with consecutive thrombocytosis as a third possible pathogenic factor for subsequent development of myocardial infarction is discussed.

    Description / Table of Contents: Summary Background: Prognosis in patients with cystic fibrosis (CF) has changed in the last years due to improved therapeutical strategies. Nephrological complications including secondary AA-amyloidosis and IgA-nephropathy are reported in literature linked with increased lifespan of CF-patients. Patients: 5 Patients developed proteinuria without erythrocyturia between the age of 24 and 40 years. Kidney biopsy demonstrated secondary AA-amyloidosis in 3 patients, and IgA-nephropathy and membraneous glomerulonephritis in the others. Proteinuria in patients with glomerulonephritis decreased spontaneously, but the course of amyloidosis patients was unfavourable. One died due to end stage renal failure 4 years after diagnosis of amyloidosis; in the second treatment with colchicine for 32 months prevented nephrotic syndrome and renal insufficiency, but later he died due to pulmonnary infectious complications. The 3rd patient with biopsy-proven amyloidosis developed severe nephrotic syndrome and gastrointestinal symptoms within 6 months and he died due to pulmonary insufficiency and exhaustion. Conclusions: Chronic inflammation and duration of the disease are well known risk factors for the development of reactive systemic amyloidosis. Periodical urinanalysis especially in adult patients is necessary, and early kidney biopsy in CF-patients with unexplained proteinuria is recommendable. Colchicine therapy may have a beneficial effect in patients with biopsy proven amyloidosis.
    Notes: Zusammenfassung Hintergrund: Die Prognose von Patienten mit Mukoviszidose hat sich in den letzten Jahren deutlich gebessert. Mit zunehmendem Lebensalter wird gehäuft über nephrologische Komplikationen, v.a. über IgA-Glomerulonephritiden und über die Entwicklung der sekundären Amyloid-A-Amyloidose (AA-Amyloidose) berichtet. Patienten: Wir berichten über 5 Patienten, die im Alter zwischen 24 und 40 Jahren eine Proteinurie ohne Erythrozyturie entwickelten. Bei 3 Patienten wurde bioptisch eine sekundäre Amyloidose, bei den beiden anderen eine IgA-Nephropathie und eine membranöse Glomerulonephritis nachgewiesen. Bei den Patienten mit Glomerulonephritis war die Proteinurie ohne therapeutische Maßnahmen rückläufig; bei Diagnose einer Amyloidose waren die Verläufe ungünstig. Ein Patient starb 4 Jahre nach Amyloidosenachweis an terminaler Niereninsuffizienz, ein weiterer Patient wurde 32 Monate lang mit Kolchizin behandelt. Ein nephrotisches Syndrom und eine Niereninsuffizienz konnten verhindert werden; der Patient verstarb jedoch an einer durch einen pulmonalen Abszeß ausgelösten Sepsis. Der 3. Patient entwickelte ein schweres amyloidbedingtes nephrotisches Syndrom und eine Magen-Darm-Amyloidose innerhalb von 6 Monaten. Er starb an schwerer Kachexie und pulmonaler Insuffizienz. Schlußfolgerungen: Bedeutsame Risikofaktoren für die Entstehung einer sekundären AA-Amyloidose sind anhaltend hohe Entzündungsaktivität und Dauer der Erkrankung. Daher sollte v.a. bei älteren Mukoviszidosepatienten auf die routinemäßige Urindiagnostik geachtet werden. Bei ersten Anzeichen einer Proteinurie ist frühzeitig zur differentialdiagnostischn Abklärung eine Nierenbiopsie durchzuführen, denn die Proteinurie kann sowohl Folge einer Glomerulonephritis als auch Symptom einer Amyloidose sein. Beim Nachweis einer Amyloidose ist eine Kolchizinbehandlung zu diskutieren, denn Patienten mit dem Vollbild einer Amyloidose haben eine schlechte Prognose.

    Notes: Abstract Two patients developed renal Fanconi syndrome (RFS) after intensive long-term chemotherapy for metastatic Ewing sarcoma and disseminated neuroblastoma. Whereas RFS was diagnosed in patient 1 before he developed osteomalacia, patient 2 experienced severe rickets and growth retardation. Renal function studies revealed slight glomerular impairment and severe tubular defects leading to increased excretion of glucose, amino acids, inorganic phosphate and low molecular weight proteins, indicating proximal tubular damage. Patient 2 additionally showed distal tubular dysfunction with acidosis and diminished concentrating capacity. Renal biopsy in patient 1 revealed marked proximal tubular defects without interstitial lymphocytic infiltration. In both patients renal damage could most likely be ascribed to previous ifosfamide (IFOS) therapy. Our patients showed no improvement in renal function after cessation of IFOS treatment, indicating a poor prognosis of once established RFS after IFOS therapy. Measurement of tubular reabsorption capacities provides exact information on the extent of tubular toxicity induced by IFOS and may be used to monitor IFOS treated patients.
