    Description / Table of Contents: Summary The behaviour of the Serum Lactate Dehydrogenase activity has been examined in 9 patients with myocardial infarction and in 6 patients with acute liver damage. The increased enzyme activity of the first group of patients decreased to the standard value of LDH 8 times slower than that of the second group. The cause of this might be the different composition of the LDH isoenzyme patterns of both diseases with the corresponding different inactivation of the enzyme activity. In 10 cases of acute myeloid leucemia the LDH isoenzyme patterns of the serum have been compared with those of the LDH in the leucemic myeloblasts of each of the respective patients. In all cases distinct differences between the encyme patterns could be proved. Compared with the composition of the LDH in the myeloblasts the composition of the serum LDH showed a decreasing surplus from the LDH I down to the LDH V. It could be excluded with reasonable certainity that other essential sources than the myeloblasts for the serum-LDH exsisted. A selective effusion of LDH isoencyme fractions out of the leucemic myeloblasts into the environs could not be proved by incubation tests. If we assume that the cause of disproportion between the enzyme patterns of the myeloblasts and the respective sera is a different quick elimination of the LDH isoenzyme fractions, then the elimination rates from LDH I to LDH V should show the following ratios: 1:1,6:4,4:11:26. They resemble those of the animal test regarding their exponential increase from LDH I to LDH V and at least similar in their range.
    Notes: Zusammenfassung Das Verhalten der Serum-Lactatdehydrogenase-Aktivität wurde bei 9 Patienten mit Myokardinfarkt und 6 Patienten mit akutem Leberparenchymschaden untersucht. Die erhöhte Enzymaktivität fiel in der ersten Patientengruppe 8mal langsamer zum Normwert ab als in der zweiten Gruppe. Als Ursache ist die sehr unterschiedliche LDH-Isoenzymzusammensetzung bei beiden Krankheitsbildern mit entsprechend unterschiedlich rasch ablaufendem Inaktivierungsprozeß für die Enzymfraktionen anzunehmen. Bei 10 Fällen akuter Paraleukoblastose wurde das LDH-Isoenzymmuster im Serum mit dem der Paraleukoblasten des jeweiligen Patienten verglichen. In jedem Fall waren deutliche Unterschiede zwischen den Enzymmustern nachzuweisen. Gegenüber der Zusammensetzung der LDH in Paraleukoblasten wies die der Serum-LDH bei allen Patienten übereinstimmend einen von der LDH I zu LDH II abnehmenden Überschuß und ein von der LDH III zur LDH V ansteigendes Defizit an Aktivität auf. In allen Fällen war ein wesentlicher LDH-Einstrom aus anderen Organzellen als den Paraleukoblasten weitgehend auszuschließen. Eine selektive Abgabe von LDH-Isoenzymfraktionen aus den Paraleukoblasten in das Umgebungsmilieu ließ sich bei Inkubationsversuchen nicht nachweisen. Setzt man als Ursache der Dysproportion zwischen den Enzymmustern der Paraleukoblasten und des jeweiligen Serums einen unterschiedlich schnellen Inaktivierungsprozeß für die LDH-Isoenzymfraktionen voraus, dann gelangt man zu Eliminationsraten, die von der LDH I zur LDH V in einem Verhältnis von 1/1,6/4,4/11/26 ansteigen. Sie gleichen den im Tierversuch ermittelten durch ihren exponentiellen Anstieg von LDH I zu LDH V und wenigstens annähernd auch in ihrer Größenordnung.

    Notes: Summary In a prospective study the efficacy of two regimens for selective decontamination of the digestive tract was studied in patients with acute leukaemia during remission induction therapy. Seventy-eight patients were randomized to receive either a combination of cotrimoxazole, polymyxin B and nystatin (group A) or a combination of nalidixic acid, polymyxin B, neomycin and nystatin. With both regimens the gastrointestinal tract could be decontaminated equally effectively from potential pathogens. In the oropharyngeal region the decontamination from Enterobacteriaceae was significantly better in group A (P〈0.01). In both groups less than 10% of the acquired infections were caused by gram-negative bacilli and no gram-negative septicaemia occurred in either group. The median time interval until the first acquired infection was 17 days in group A and 36 days in group B, respectively (P〈0.05). It is concluded that regimen A might be more effective than regimen B though both regimens prevent reliably severe gram-negative infections.

    Notes: Summary Twenty-nine adult patients with acute myelogenous leukemia AML who received 40 treatment courses with high dose cytosine arabinoside (HD-A), alone or combined with other cytotoxic drugs, for remission induction (RI) or postremission intensive consolidation (IC) were retrospectively analysed for types and severity of infectious complications. In this paper, we report the unusually high rate of streptococcal septicemia in our patients. Of 13 bacteremic infections in a total of 45 infectious episodes, 10 were caused by streptococci (9 viridans streptococci, 1 group B hemolytic streptococcus). Three of them were lethal. After reviewing all documented cases of streptococcal septicemia in the same study period, four additional cases among adult patients with AML were identified. Three of them have had antileukemic chemotherapy without HD-A, while one have had HD-A as a conditioning regimen for bone marrow transplantation. Only three cases were documented to occur in adult patients with AML. Patients treated with HD-A for RI or IC had a significantly lower risk of streptococcal septicemia during previous chemotherapy-associated febrile neutropenic episodes (1/55 vs 10/45;P=0.01). Neither prophylactic regimens including trimethoprim-sulfamethoxazole nor those without it were effective in preventing streptococcal septicemia. Further studies are needed to confirm these data before the value of additional or alternative prophylactic antibiotics is proven necessary.

    Notes: Summary From 1972–1983 53 patients underwent bone marrow transplantation. The median age was 18 years (3–41). 27 patients suffered from severe aplastic anaemia, 22 patients had acute leukaemia and 4 patients had chronic granulocytic leukaemia in chronic phase. Out of 22 patients with acute leukaemia, 2 had florid leukaemia, 2 had an early relapse and 18 patients were in first or second remission of their disease. 2/53 patients received a syngeneic transplant, 51/53 patients an allogeneic transplant. 47/51 patients had a HLA-A, B, C-identical, MLC-negative sibling donor, 1/51 had a HLA-A, B-C-identical, MLC-positive sibling donor, 2/51 a HLA-phaenotypical identical parental donor and 1/51 a HLA-identical, MLC-negative unrelated donor. The comparison of the results obtained in patients with severe aplastic anaemia transplanted from 1972–1979 with those transplanted from 1980–1983 shows that the bone marrow transplantation has to be performed in an early stage of the disease before the patients become multiple transfused, sensitized and severely infected and that the conditioning regimen for polytransfused patients has to be more intensive than in untransfused patients. From the patient group transplanted 1972–1979, only 1/14 patients is a long-term survivor in contrast to 8/13 patients transplanted from 1980–1983. 11/22 patients with acute leukaemia are alive between more than 5 years and 14 days after bone marrow transplantation. Only 1/4 patients, who were transplanted not in remission, is alive. For patients with acute leukaemia the bone marrow transplantation should be performed in an early stage of their disease when the tumor burden is small and when the patients are in good clinical condition. 2/4 patients with CGL are alive between 12 months and 3 months after bone marrow transplantation. In our patient group graft versus host disease was the most important problem with a high mortality due to GvHD associated infections.

    Notes: Summary The impact of aggressive chemotherapy on reproductive and endocrine gonadal function was prospectively studied in 44 patients with germ cell tumors. Diagnostic procedures to determine gonadal toxicity consisted of hormone determinations, semen analyses, interviews with a standardized questionnaire, and gonadal histology. After chemotherapy all patients showed elevated serum levels of follicle-stimulating hormone (FSH) and azoospermia due to germ cell and stem cell loss. Recovery of spermatogenesis, as indicated by normalization of serum FSH levels and sperm density, occurred in 77% of the patients 25–60 months after cessation of chemotherapy. In all patients serum testosterone and luteinizing hormone (LH) values remained within normal limits after therapy indicating resistance of Leydig cells to cytotoxic drugs. Three patients fathered four healthy children after completion of chemotherapy. These data suggest significant reproductive dysfunction in all men treated for germ cell tumors. However, most patients showed late and complete recovery of spermatogenesis. In contrast, endocrine gonadal function was unaffected after chemotherapy in all patients. FSH and LH are feasible markers to assess drug-induced gonadal toxicity.

    Description / Table of Contents: Summary Growth of mononuclear cells from human peripheral blood from 10 normal individuals was tested in diffusion chamber culture over a period up to 17 or 21 days. After an initial decrease during the first few days an increase of the total cell number was observed with maximal values on day 13. In all individuals growth of undifferentiated blast cells, lymphocytes, plasma cells, immature and mature granulopoietic cells, macrophages, and megakaryocytes occurred. In all individuals the different cell types had similar growth patterns in diffusion chamber culture. The considerable numerical variations which were seen in the granulopoietic cells were probably due to different stem cell concentrations in the peripheral blood of the investigated individuals. The results indicate that the diffusion chamber technique is a valuable method for the detection of haemopoietic stem cells and the culture of lymphocytic cells in man.
    Notes: Zusammenfassung Das Wachstum mononukleärer Zellen des peripheren Blutes in der Diffusionskammerkultur wurde bei 10 Normalpersonen über einen Zeitraum von 17 bis 21 Tagen untersucht. Während der Kultur kam es nach einem initialen Abfall zu einem Anstieg der Gesamtzellzahl mit einem Maximum am 13. Tag. Bei allen untersuchten Individuen zeigte sich eine gute übereinstimmung in den Wachstumsmustern der einzelnen Zellarten. Erhebliche numerische Schwankungen wurden jedoch bei den granulopoetischen Zellen beobachtet, wo sie auf unterschiedliche Stammzellkonzentrationen im Blut der untersuchten Personen zurückgeführt werden müssen. Die Ergebnisse zeigen, da\ die Diffusionskammertechnik eine wertvolle Methode zum Nachweis hämopoetischer Stammzellen und zur Kultur lymphatischer Zellen beim Menschen darstellt.

    Description / Table of Contents: Summary The efficiency of strict reverse isolation and antimicrobial decontamination in remission induction therapy of acute leukemia was studied retrospectively in 47 patients who were treated with a standardized aggressive chemotherapy of daunorubicin and cytosine arabinoside. Twenty-two patients were treated in strict reverse isolation with antimicrobial decontamination and 25 patients in the open ward without any measures against infections. In the patients in isolation the incidence of new infections per patient was 0.77 compared to 1.42 in the control group. The rate of complete remissions was 77% in the patients in isolation vs. 56 % in the control patients.
    Notes: Zusammenfassung Die Wirksamkeit von strikter reverser Isolation und antimikrobieller Dekontamination bei der Induktionstherapie der akuten LeukÄmie wurde retrospektiv bei 47 Patienten untersucht. Alle Patienten erhielten eine standardisierte aggressive Chemotherapie mit Daunorubicin und Cytosin-Arabinosid. Zweiundzwanzig Patienten wurden in strikter reverser Isolation mit antimikrobieller Dekontamination behandelt, 25 Patienten auf normalen Krankenstationen ohne Ma\nahmen zur Infektionsprophylaxe. Die HÄufigkeit neuer Infektionen pro Patient war 0,77 bei den isolierten Patienten und 1,42 in der Kontrollgruppe. Die Rate kompletter Remissionen betrug bei den isolierten Patienten 77% im Vergleich zu 56% bei den Patienten auf den normalen Krankenstationen.

    Notes: Summary Common manifestations of Wilson's disease are disorders of the liver and brain. A rare complication of this inherited disease is acute intravascular haemolytic anaemia. We report the case of a 33-year old female patient who was admitted to the hospital with acute haemolysis as the initial symptom of Wilson's disease. The haemolysis preceded the definitive diagnosis by 20 months. It is concluded that in any case of unclear haemolytic anaemia, especially in adolescents or in young adults, Wilson's disease should be considered.
