    Notes: Homozygous typing cells (HTC) for two new HLA-D determinants, EI and RE, defined by family studies, are described. The HLA-D typing experimtens among more than 300 unrelated individuals showed phenotype frequencies of 0.045 for El and 0.098 for RE. Since the tested population was also typed for its HLA-A and -B alleles, linkage disequilibrium parameters could be calculated: HLA-D type El was statistically significantly associated with HLA-B13 and Bwl7, HLA-D type RE with HLA-Bw40. These data support the working hypothesis that both EI and RE are new alleles of the HLA-D series.

    Description / Table of Contents: Zusammenfassung Im Rahmen der Arbeitsgemeinschaft Knochenmarktransplantation München wurden von August 1975 bis Juni 1980 insgesamt 17 Patienten mit rezidivierter, akuter Leukämie mit Knochenmark von HLA-identischen Geschwistern transplantiert. Die antileukämische und immunsuppressive Vorbehandlung bestand aus BCNU, Cytosin-Arabinosid, Cyclophosphamid in hoher Dosierung und Ganzkörperbestrahlung mit etwa 9 Gy Körpermitteldosis an einer60Co-Doppelbestrahlungsanlage. Die Prophylaxe einer Graft-versus-Host Krankheit (GvHK) wurde in allen Fällen mit Methotrexat durchgeführt, bei neun Patienten wurde als zusätzliche GvHK-Prophylaxe das Knochenmark mit Anti-T-Zell-Globulin inkubiert, von dem die Antikörper gegen hämopoetische Stammzellen absorbiert waren. Zwei von fünf auswertbaren Patienten, die unbehandeltes Knochenmark erhalten hatten, entwickelten chronische GvHK, während kein Patient nach ATCG-Inkubation des Knochenmarkes eindeutige GvH-Krankheit bekam. Sechs Patienten leben in Vollremission zwischen einem und 33 Monaten nach Knochenmarktransplantation (KMT). Fünf Patienten starben mit Rezidiven zwischen 3 1/2 und 24 Monaten nach KMT, drei Patienten mit interstitieller Pneumonie innerhalb von 3 Monaten nach KMT und drei Patienten innerhalb von 4 Wochen ohne ausreichende Knochenmarkfunktion. Vier von 13 Patienten, die vor mehr als 6 Monaten transplantiert wurden, überleben zur Zeit 11, 14, 19 und 33 Monate in Vollremission. Unsere Ergebnisse bestätigen, daß selbst in fortgeschrittenen Stadien akuter Leukämie durch KMT noch langfristige Remissionen erreichbar sind.
    Notes: Summary Seventeen patients with relapsed, acute leukemia were grafted with bone marrow from HLA-identical siblings by the ‘Munich Cooperative Group for Bone Marrow Transplantation’ during the period from August 1975 to June 1980. The antileukemic and immunosuppressive conditioning treatment consisted of high doses of Bischlorethyl nitrosourea, Cytosine-Arabinoside and Cyclophosphamide, as well as, total body irradiation of about 9 Gy (midline body dose) from dual60Cobalt sources. Methotrexate was given to all patients for prophylaxis of graft-versus-host disease (GvHD). Nine patients received marrow that was treated with anti-T-cell globulin (ATCG) “in vitro”. — Crossreacting antibodies against hemopoietic stem cells were removed by absorption. Two of 5 evaluable patients given untreated marrow developed chronic GvHD, while patients given ATCG-treated marrow did not show unequivocal symptoms of GvHD. Six patients are in complete remission one to 33 months following bone marrow transplantation (b.m.t.) Five patients died with relapses of leukemia between 3 1/2 and 24 months following b.m.t., 3 patients died with interstitial pneumonia within 3 months of b.m.t. and 3 patients died with insufficient graft function within 4 weeks of b.m.t. Four of thirteen patients that were grafted more than 6 months ago are presently alive and in continuous complete remission at 11, 14, 29 and 33 months following b.m.t. Our results confirm that longterm remissions can be obtained with b.m.t. in patients with acute leukemia in advanced stage.

    Description / Table of Contents: Zusammenfassung Im Rahmen der Arbeitsgemeinschaft Knochenmarktransplantation — München (AG-KMT) wurden vom März 1975 bis Mai 1980 insgesamt 12 Patienten wegen schwerer, aplastischer Anämie mit Knochenmarktransplantation (KMT) behandelt. Sechs Patienten überleben derzeit mit normalem Blutbild und Knochenmark zwischen 10 Monaten und mehr als 5 Jahren nach KMT von HLA-identischen Geschwistern, eine Patientin steht noch in ambulanter Behandlung wegen lokalisierter, chronischer Graft-versus-Host Krankheit (GvHK), fünf Patienten sind klinisch gesund. Sechs Patienten starben, ein Patient starb am Tag vor KMT mit Hirnblutung, drei Patienten 32, 40 und 55 Tage nach KMT an den Folgen der Transplantatabstoßung, einer an schwerer GvHK 85 Tage nach KMT und einer 87 Tage nach KMT vermutlich an interstitieller Pneumonie nach Hirnblutung. Drei von 6 Patienten, die nur mit Cyclophosphamid (CY) vorbehandelt waren, starben infolge Abstoßung des Transplantates. Zwei erwachsene Patienten, die mit CY und „total lymphoid irradiation“ vorbehandelt waren, und drei Kinder, die nach KMT unbestrahlte Leukocytenkonzentrate von Knochenmarkspender erhalten hatten, stießen das Transplantat nicht ab. Die Ergebnisse der AG-KMT sind vergleichbar denen großer, spezialisierter Zentren für KMT und zeigen die Möglichkeiten einer Heilung schwerer aplastischer Anämien durch KMT von HLA-identischen Geschwistern. Die Erfolge sind besser bei frühzeitiger KMT.
    Notes: Summary From March 1975 until May 1980 twelve patients with severe aplastic anemia were grafted with bone marrow from HLA-identical siblings by the Munich Cooperative Group for Bone Marrow Transplantation. Six patients are alive between 10 months and more than 5 years after grafting with normal blood values and marrow. One patient is treated as an out patient for chronic localized graft-versus-host disease (GvHD), five patients are well and without treatment. Six patients have died, one patient with a cerebral hemorrhage the day before transplantation, three patients following rejection of grafts 32, 40 and 55 days after grafting, one patient with severe GvHD 85 days after grafting and one patient, probably with interstitial pneumonia, following cerebral hemorrhage. Three of 6 patients who were conditioned with Cyclophosphamide (CY) only died following rejection of the graft. Two adults who were conditioned with CY and “total lymphoid irradiation” and three children, who were given unirradiated leukocyte concentrates from the marrow donor after grafting, did not reject their grafts. The results of the Munich-Cooperative Group for Bone Marrow Transplantation are comparable to those of large, specialized centers for bone marrow transplantation, they indicate possibilities of cure of severe aplastic anemia by marrow grafts from HLA-identical siblings. They confirm that better results are obtained with earlier transplantation in the course of the disease.

    Notes: Summary The specificity of an antiserum against ALL-cells lacking B-and T-cell markers was characterized. The antiserum was used in several indicator systems to investigate the expression of leukaemia-associated antigens on normal lymphocytes, lymphoid cell lines and various leukaemia cells. The relevance of such antisera for the detection and classification of leukaemic cell populations is discussed.

    Notes: Summary The lymphoblasts from 100 patients with acute lymphocytic leukaemia were investigated for the expression of receptors for sheep erythrocytes (E) and of a specific heterologous T cell antigen (T). In 17 cases, both T cell markers were expressed simultaneously on the leukaemic cells. In 13 cases only T antigens could be demonstrated on the lymphoblasts. A quantitative analysis of T antigens by immunoautoradiography revealed that the T expression of E−T+-lymphoblasts was in general like that of E+T+-lymphocytes in the blood of normal persons, in several cases even higher. Therefore, the failure of E-rosette formation cannot be correlated to a decrease of the other T cell differentiation marker. In 7 out of 9 tested cases, a strong acid phosphatase reaction product located paranuclearly could be demonstrated. Complement-receptors were expressed in 3 of 5 cases which were also demonstrated in some cases of the E+T+-ALL group. The latter group was characterized by a T antigen expression like that of thymocytes. 4 cases of the E−T+ALL group were adults. Since the leukaemia cells of 2 cases were negative for acid phosphatase, PAS and all surface markers including cALL antigen, the T antigen can classify undifferentiated and otherwise unclassificable leukaemias. The clinical significance of the E−T+-ALL seems to be important since 5 out of 9 children with this type of ALL died soon after diagnosis.

    Description / Table of Contents: Summary An in vitro incubation of incompatible donor bone marrow by xenogenic anti-T-cell globulin (ATG) suppressed an otherwise lethal GvH reaction in animal models. An application of this principle to clinical bone marrow transplantation was successfully tried in three patients with acute lymphoblastic leukemia. Preparation of the specific anti-human T-cell globulin (ATCG-H) was carried out by absorption of anti-human thymocyte globulin with liver-kidney homogenate, chronic lymphocytic leukemia cells of B-cell type, and erythrocytes. Subsequent testing revealed that the serum still reacted with human T-cells but no longer reduced the number of colony-forming units in culture (CFU-C). All three bone marrow recipients were treated by chemotherapeutic conditioning and total body irradiation followed by grafting of in vitro treated bone marrow from HLA-identical siblings. The transplantation of the bone marrow was well tolerated and no major side effects were encountered. No patient so far (24, 7, 6 months) has shown any signs of GvHD. The in vitro pretransplantation treatment of bone marrow with anti T-globulin may be a new approach to the prevention for GvHD in man.
    Notes: Zusammenfassung Tierexperimentelle Befunde ergaben den Hinweis, daß bei Knochenmarktransplantation mit inkompatiblem Spendermark eine Vorinkubation des Spendermarkes mit xenogenem Anti-T-Zell-Globulin eine sonst toxisch verlaufende Graft versus Host-(GvH)Erkrankung vermeidet. Bei drei Patienten mit akuter lymphatischer Leukämie wurde dieses Prinzip bei der Knochenmarktransplantation erfolgreich klinisch angewandt. Zur Anwendung gelangte ein spezifisches antihumanes Anti-T-Zell-Globulin (ATCG-H), das durch mehrere Absorptionsschritte aus rohem antihumanem Globulin (ATG) gewonnen wurde. Eine Vortestung des Serums ergab eine unveränderte Reaktion gegen menschliche T-Zell-Lymphozyten ohne toxische Nebenwirkungen auf in vitro nachweisbare Vorläuferzellen der Hämopoese (CFU-C). Die Knochenmarktransplantation wurde bei allen drei Patienten nach üblicher Chemotherapie („Konditionierung“) und Ganzkörperbestrahlung mittels vorinkubiertem Spendermark von HLA-identischen Geschwisterndurchgeführt. Toxische Nebenwirkungen durch die Vorinkubation traten nicht auf. Anzeichen einer GvH wurden bisher (24, 7, 6 Monate) bei den Empfängern nicht beobachtet. Die in vitro -Vorinkubation von Spenderknochenmark kann somit als ungefährlicher neuer Versuch zur Vermeidung einer GvH beim Menschen empfohlen werden.

    Description / Table of Contents: Zusammenfassung Hämatologische und immunsuppressive Wirkung von einmaligen Stickstofflost(HN3)-Gaben wurde an 20 Hunden untersucht. HN3 verursachte bei allen Tieren eine starke Erniedrigung der peripheren Blutwerte. Bei Hunden, die die akute gastrointestinale Toxizität von HN3 überlebten, war die Erholung der Gesamtleukozyten am Tag 15 vollständig. Die Wiederherstellung der Ausgangswerte von Thrombozyten und Lymphozyten nahm einen protrahierteren Verlauf. Granulopoetische Vorläuferzellen (CFU-C) im Knochenmark wurden durch in vitro Kulturen bestimmt. Die CFU-C-Konzentrationen waren einen Tag nach der Behandlung mit HN3 deutlich vermindert, zeigten aber selbst nach nahezu letalen Dosen schnelle Regeneration zu Normalwerten innerhalb 4 bis 7 Tagen. Die reduzierte Fähigkeit von Hundelymphozyten, nach Stimulation mit Mitogenen in vitro zu proliferieren, wies auf eine langanhaltende Beeinträchtigung der zellulären Immunfunktion bei HN3-behandelten Hunden hin. Die humorale Immunfunktion war ähnlich betroffen, wie sich aus der verminderten und verzögerten Bildung von Antikörpern gegen Schaferythrozyten ergab. Zusammenfassend lassen unsere Ergebnisse eine unterschiedliche Wirkung von HN3 auf lymphatische und myeloische Vorläuferzellen vermuten.
    Notes: Summary Hématologic and immunosuppressive effects of single doses of nitrogen mustard (HN3) were evaluated in 20 dogs. HN3 caused profound depression of peripheral blood counts in all animals. Recovery of total white blood cell counts in dogs surviving the acute gastrointestinal toxicity of HN3 was complete by day 15. Recovery of platelet and lymphocyte counts to initial levels took a more prolonged course. Granulopoietic progenitor cells (CFU-C) in the bone marrow were assayed by an in vitro culture system. Concentrations of CFU-C were markedly decreased one day after HN3-treatment, but showed at near-lethal doses rapid restoration to normal values within 4 to 7 days. Cellular immune function of HN3-treated dogs was impaired for prolonged periods as indicated by the reduced capacity of canine lymphocytes to prolifferate in vitro in response to stimulation with mitogens. Humoral immune function was similarly affected as determined by the depressed and delayed antibody formation against an intravenous challenge with sheep red blood cells. In conclusion, our results suggest a different effect of HN3 on lymphoid and myeloid precursor cells.

    Notes: Summary Anti-human-thymocyte globulin (AHTZG) was applied to prevent GvHD in clinical bone marrow transplantation. AHTZG produced by absorption with several cell preparations reacted specifically with T-lymphocyte populations and was no longer inhibitory to human CFUc and bone marrow growth in diffusion chambers. Marrow grafts of 14 patients with ALL were incubated in vitro with AHTZG and transferred to the recipients conditioned with antileukemic chemotherapy and total body irradiation of 1000 rad. Ten patients were transplanted after relaps, four patients during remission. The patients tolerated the marrow without side effects and a hemopoietic engraftment was seen in 12 cases. Three patients showed signs of GvHD on the skin, two of them showed later on also manifestations in the liver. In the other cases no GvHD could be detected. Five out of 14 patients are still alive between 144 and 964 days post transplantation in remission.

    Notes: Summary One hundred and eight children with acute lymphocytic leukemia (ALL) were admitted to a prospective therapeutic regime. Remission induction was achieved in 94% of the cases with vincristine, L-asparaginase, adriamycine and prednisone. One hundred and one patients received three intermediate dose methotrexate (MTX) infusions combined with intrathecal MTX, followed by L-asparaginase 24 h later. High risk (HR) patients (n=50) were treated in addition with high dose cyclophosphamide and Ara-C over 3 weeks. One hundred and one patients received cranial irradiation (1,800 rads standard risk (SR)-patients, 2,400 rads HR-patients) and intrathecal MTX. Maintenance therapy was performed with the usual two drug combination of daily 6 mercaptopurine (6 MP) and weekly MTX orally. Based on phenotyping 67% of patients had common type ALL, and pre-T or T-cell type in 18%. Six per cent of the patients had leukemic blasts expressing both common ALL and T-cell markers (c/T-type); 9% had acute undifferentiated leukemia (AUL). Out of 108, 101 achieved a complete remission, 6 patients died during induction therapy, 1 was a non-responder and 9 patients relapsed. Of these 6 had haematological relapses, 2 had CNS relapse and 1 had a testicular relapse. Four patients died in continuous complete remission (CCR). For 101 patients the 30 months probability of CCR is 0.85 (± 0.05). For 51 patients with standard risk CCR probability is 0.98 (± 0.03), for 50 patients with high risk indices it is 0.65 (±0.11). Patients with c-ALL have a CCR survival of 0.85 (±0.07), those with T- or pre-T-ALL 0.88 (±0.09), all 5 patients with c/T-ALL alive in CCR. In our study pediatric AUL patients have the most unfavourable prognosis.
