    Description / Table of Contents: Summary 2 weeks after initiation of carbamazepine therapy a 3 year old boy presented with skin rash, fever, lymphadenopathy, hepatosplenomegaly and nephritis. After exclusion of infectious diseases our differential diagnosis focussed on carbamazepine induced hypersensitivity syndrome. We found a positive lymphocyte transformation assay and patch test to carbamazepine, indicating a specific response, but no anti-carbamazepine antibody, no circulating immune complexes and no decrease in complement components. The hypersensitivity syndrome refers to a severe hypersensitivity response due to a idiosyncratic reaction. The origin is unknown. The similarity to other multisystem disorders is discussed. Discussion: Not only aromatic antiepileptic agents (carbamazepine, phenobarbital, phenytoin) sulfonamides but as well allopurinol and gold salts are associated with the syndrome. Withdrawal of the drug and treatment with corticosteroids usually lead to complete recovery.
    Notes: Zusammenfassung Wir berichten über einen 3 jährigen Jungen, der 2 Wochen nach Beginn einer antiepileptischen Behandlung an einem Carbamazepin-induzierten Hypersensitivitätssyndrom, bestehend aus therapieresistentem Fieber, polymorphem Exanthem, oropharyngealen Läsionen, generalisierter Lymphadenopathie, Hepatosplenomegalie und Nephritis, erkrankte. Wir fanden positive Lymphozytenstimulations- und Epikutantests auf Carbamazepin als Ausdruck einer spezifischen Überempfindlichkeit. Spezifische Anti-Carbamazepin-Antikörper, zirkulierende Immunkomplexe oder eine Komplementerniedrigung waren nicht nachweisbar. Es handelt sich um eine Überempfindlichkeitsreaktion unbekannter Ätiologie im Sinn einer Idiosynkrasie. Nach Ausschluß infektiöser Ursachen wird die Differentialdiagnose zu anderen Systemerkrankungen erörtert. Diskussion: Neben aromatischen Antikonvulsiva (Carbamazepin, Phenobarbital, Phenytoin) sind Sulfonamide und Goldsalze mögliche Auslöser eines Hypersensitivitätssyndroms. Absetzen des Induktors und systemische Kortikosteroide führen in der Regel zur vollständigen Remission.

    In vivo activity of asialo-erythropoietin in combination with asialo-glycoproteins (1982)

    Notes: Summary In vitro active asialo-erythropoietin has no effect on hemesynthesis in vivo. Asialo-glycophorin induces a very low 59Fe-uptake rate in heme in exhypoxic polycythemic mice. The combination of asialo-erythropoietin and asialo-glycophorin or asialo-fetuin induced an activation comparable to the activation by native erythropoietin. Obviously the combination of asialo-erythropoietin and tested glycoproteins influence the activity of erythropoiesis-stimulating capacity of asialo-erythropoietin.

    Influence of haemodialysis and renal transplantation on trace element concentrations in children with chronic renal failure (1986)

    Notes: Abstract Whole blood levels of Cd and Pb (μg/g Hb), serum concentrations of Sr and Zn and their urinary excretion were measured in healthy, renal transplant and dialyzed children by atomic absorption spectroscopy. Furthermore, before and after dialysis the concentrations of these elements were determined in blood/serum as well as in the dialysis fluid. The predialytic concentrations of Cd, Pb and Sr in blood/serum were significantly increased compared to controls. Haemodialysis had only minor effects on whole blood Cd and Pb levels but serum Sr and Zn concentrations increased as a result of high metal levels in dialysis fluid. Children after renal transplantation showed no alterations in Pb, Sr and Zn concentrations compared to healthy children but whole blood Cd was increased. According to the renal function the Pb, Cd and Zn urinary excretion decreased in the following order: healthy, renal transplant and dialysis children. Sr urinary excretion was increased in haemodialysis and renal transplant patients. In conclusion, we found no Zn deficiency. Elevated blood levels of Cd and Pb and elevated Sr serum concentrations in paediatric patients undergoing dialysis and increased Cd whole blood levels in renal transplant children could be of clinical interest.

    Notes: Abstract Anaemia is a frequent symptom in children with chronic uraemia. There is only limited information about committed haemopoietic stem-cell function in renal insufficiency. The ability of bone-marrow cells to form erythropoietic and granulopoietic cell colonies in vitro was therefore tested in 13 children with chronic renal insufficiency. Following separation of mononuclear cells from bone-marrow aspirates by Ficoll-Isopaque gradient centrifugation, erythropoietic precursor cells were stimulated in plasma clots by erythropoietin. Granulopoietic precursor cells were stimulated in soft-agar gel using feeder layers of normal human leukocytes. The colonies were identified by staining and counted. The number and proliferative capacity of erythropoietic precursor cells (CFU-E) did not seem to be significantly suppressed. Under in vitro conditions, the responsiveness of CFU-E to erythropoietin seemed to be normal. Addition of autologous serum resulted in different degrees of inhibition of erythroid colony formation. The inhibitory effect of the sera was also obvious when uraemic sera were added to bone-marrow cells from subjects without renal disease. Preliminary data indicate that haemodialysis is effective in reducing this inhibitory activity which may be an important factor in the pathogenesis of anaemia in chronic renal insufficiency. The numbers and proliferative capacity of granulopoietic precursor cells (CFU-C) were normal in all the children tested.
