    Description / Table of Contents: Summary Complete blood counts, bone marrow aspirations and autoradiographs of bone marrow smears were performed in twelve persons to whom Thorotrast (thorium dioxyde) had been given intravenously about 20 yars ago. Peripheral blood cell counts were within normal limits in all subjects; however, marrow smears of ten persons showed increased erythropoiesis. Furthermore an increase of binucleated red cell precursors which normally are rarely found, was noted. Thorotrast deposits were present in all marrow smears, and autoradiographs demonstrated many alpha-tracks radiating from the incorporated radio-active material. The question arises whether the cytologic abnormalities in the erythroblasts are due to the effect of continous exposure to low levels of ionising radiation.
    Notes: Zusammenfassung Bei 12 Personen, die vor ca. 20 Jahren Thorotrast erhalten hatten, wurden eine Blut- und Knochenmarkuntersuchung durchgeführt und von den Markausstrichen Autoradiographien angefertigt. Während das periphere Blutbild keine wesentlichen Abweichungen von der Norm zeigte, fand sich in 10 Fällen eine gesteigerte Erythropoese im Mark und in 8 Fällen das gehäufte Vorkommen von binukleären roten Vorstufen. Das Vorhandensein von Thorotrast im Knochenmark wurde autoradiographisch durch den Nachweis von α-Spuren im Bereich phagozytierender Retikulumzellen bestätigt. Es wird diskutiert, ob es sich bei den beobachteten mitoseabhängigen Zellatypien um Spätfolgen einer sogenannten “low level exposure” handeln könnte.

    Description / Table of Contents: Summary During the German 1964 Himalayan expedition, which reached its goal by conquering the 7,349-m-high Talung Peak for the first time, studies were carried out concerning the erythropoietic action of high altitude climate. For the determination of the erythrocyte number, blood was collected in a Gowers-Kleine solution and studied with the Hellige “Erymat” in Germany, after the termination of the expedition. Despite the most severe conditions (temperature influences of −20 to +40° C, etc.), this method produced perfectly utilizable results. Accordingly, this method, which proved its values for the general laboratory a long time ago, can also be highly recommended for expeditions to high altitudes.
    Notes: Zusammenfassung Während der Deutschen Himalaya-Expedition 1964, die ihr Ziel mit der Erstbesteigung des 7349 m hohen Talungpeak erreicht hat, sind Untersuchungen über die erythropoetische Wirkung des Höhenklimas durchgeführt worden. Zur Bestimmung der Erythrozytenzahl wurde das Blut inGowers-Kleine-Lösung abgenommen und nach Beendigung der Expedition in Deutschland mit dem Hellige-Erymat untersucht. Trotz schwerster Bedingungen (Temperatureinflüsse −20 bis +40°C usw.) konnten mit dieser Methode tadellos verwertbare Ergebnisse erhalten werden. Die Methode, die sich im Routinelabor längst bewährt hat, kann somit auch für Hochgebirgsexpeditionen bestens empfohlen werden.

    Description / Table of Contents: Zusammenfassung Bei 47 Patienten mit akuter Leukämie wurden die Ergebnisse einer voneinander unabhängigen Klassifizierung aufgrund der panoptischen Färbung einerseits und dem Ausfall cytochemischer Reaktionen andererseits (Peroxydase, PAS-Reaktion, Naphthol-AS-Acetat-Esterase) sowie das Ansprechen auf eine adäquate Induktionstherapie in den cytologisch und cytochemisch definierten Gruppen miteinander verglichen. In 42 Fällen stimmte die cytologische und cytochemische Differenzierung miteinander überein. Hinsichtlich des Ansprechens auf Therapie ergeben sich keine signifikanten Unterschiede, gleichgültig, ob man die AL nach cytologischen oder cytochemischen Kriterien gruppiert. Eine Ausnahme bildet der bei undifferenzierten AL cytochemisch charakterisierbare PAS-Typ, bei dem ein besseres Ansprechen auf Therapie als bei den Fällen ohne diagnostisch verwendbare cytochemische Aktivität wie auch bei den granulocytär differenzierten AL gefunden wurde. Hinsichtlich des Ansprechens auf Therapie verhalten sich die Erwachsenen mit PAS-Typ ähnlich günstig wie die Kinder.
    Notes: Summary The leukaemic blast cells of 47 cases of acute leukaemia have been independently subclassified on the basis of panoptic stains on the one side and cytochemical reactions (peroxydase, PAS, naphthol-AS-acetate-esterase) on the other. In 42 cases the results of the cytochemistry were concordant to those of the panoptic stains. The percentage of responders to adaequate inductive chemotherapy failed to show any differences between the groups defined according to the different criteria. However, within the group of acute leukaemias which on the basis of panoptical staining could not be attributed to one of the normal cell lines, patients with PAS-positive leukaemic cells seem to have a better response than all other cases. This may be true for adults as well as for children.

    Description / Table of Contents: Zusammenfassung Sechs Patienten mit einer immunoblastischen Lymphadenopathie wurden beobachtet. Es wurden charakteristische morphologische und klinische Merkmale gefunden, die eine Abgrenzung von malignen lymphoproliferativen Erkrankungen einerseits und von benignen Pseudolymphomen andererseits gestatten. Zur klinischen Symptomatik gehören ausgeprägte subjektive Beschwerden, generalisierte Lymphknotenschwellungen, Hepatosplenomegalie, Hauterscheinungen, sowie der Nachweis von quantitativ und qualitativ pathologischen Reaktionen im B-Zell-Plasmazell-System wie Hypergammaglobulinämie, passageres Auftreten von Autoantikörpern und Erscheinen von Plasmazellen im peripheren Blut. Kriterien für eine maligne Neoplasie fehlen. Der Verlauf kann trotzdem rasch progredient zum Tode führen, wobei die Infektanfälligkeit als Todesursache im Vordergrund steht. Andererseits sind auch spontan remittierende Verläufe über viele Jahre zu beobachten. Zur Therapie sind vorwiegend supportive Maßnahmen zu empfehlen; Immunosuppressiva, vor allem Nebennierenrindensteroide, können vor allem bei immunologischen Komplikationen einen positiven Effekt haben.
    Notes: Summary Six patients have been observed which exhibited the features of the so called immunoblastic lymphadenopathy. The histological and clinical findings allow to distinguish the disease from both the malignant lymphomas and other forms of benign pseudolymphomas. The most important clinical features are severe general symptoms, generalised lymphadenopathy, hepatosplenomegaly, skin rash and a variety of abnormal reactions in the B-cell system such as hypergammaglobulinaemia, a transient positive Coombs test and the appearance of plasma cells in the peripheral blood. Evidence for a neoplastic nature of the disease is lacking. Nevertheless, the course of the disease may be progressive and fatal, but spontaneous remissions and subsequent relapses have also been observed. Supportive measures are at present the most essential part of the therapeutic strategy. Immunosuppressants such as corticosteroids may have a positive effect in cases with immunological complications.

    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: Abstract In 15 infants with severe combined immunodeficiency (SCID), immunological reconstitution was attempted by bone marrow transplantation (BMT) from HLA-haploidentical parents. To prevent graft versus host disease (GvHD), marrow grafts were depleted of contaminating T-lymphocytes using lectin agglutination and rosette formation with sheep red blood cells. Thirteen patients received transplants without undergoing prior cytoreductive conditioning. Eleven of these developed donor-dependent T-cell functions, two failed to do this. One of these two as well as two further patients received cytoreductive treatment prior to repeat and to first transplants and in two, complete lymphohemopoietic reconstitution was observed. Of the 15 patients who received transplants, 11 are currently alive. Two recently treated patients remain in the hospital, nine are at home with stable T-cell functions. Normal humoral immune functions have developed upto now in three patients. In the others, gammaglobulins are regularly substituted. Complications of acute or chronic GvHD were not observed with the exception of one case who developed transient GvHD of the skin. These results suggest that in a majority of patients with SCID, T-cell functions can develop without GvHD following haploidentical, T-cell-depleted BMT. Exceptional patients require preconditioning to allow donor cell engraftment, an approach that also appears to facilitate reconstitution of humoral immune functions

    Notes: Summary In two patients with acute leukaemia, the development of progressive interstitial pulmonary fibrosis was observed following chemotherapy with BCNU, Cytoxan and Ara-C. The x-ray changes were accompanied by restrictive changes of pulmonary function and, later on, by severe hypoxia. Serologic tests did not reveal infection with cytomegaly virus or mycoplasma pneumoniae. These findings, together with reports in the literature, suggest a toxic effect of BCNU on the lung. The combination with Cyclophosphamide may contribute to this toxic reaction.
