    Description / Table of Contents: Zusammenfassung Neben medikamentöser Therapie kommt der supportiven Transfusionstherapie mit Blutzellen in der Behandlung der Knochenmarksinsuffizienz zentrale Bedeutung zu. Neu entwickelte Verfahren zur Separation von Blutzellen und grundlegende Erkenntnisse über deren Antigenizität ermöglichen eine rationell angelegte und therapeutisch effektive Substitution bei Mangelzuständen einzelner Blutzelltypen. Durch Verwendung leukocyten-und thrombocytenarmer Erythrocytenpräparationen werden Alloimmunisierung gegen leukocyten- und thrombocytengebundene Antigene und nicht-hämolytische Transfusionsreaktionen vermieden. Längerwährende effektive Thrombocytensubstitution ist, als Folge der unvermeidlichen Alloimmunisierung, nur mit Thrombocyten HL-A-kompatibler Spender möglich. Die klinische Bedeutung von Granulocytentransfusionen ist derzeit noch nicht endgütlig zu beurteilen, jedoch bestätigen erste Untersuchungen ihre therapeutische Wirksamkeit.
    Notes: Summary Supportive care with blood component transfusions has greatly improved prognosis in patients with bone marrow failure. This progress has been made possible by newly developed techniques for separation of blood cells and by a better understanding of the antigenicity of human blood cells and of immunologic reactions following their transfusion. Transfusion of white cell and platelet-poor red cell preparations prevents alloimmunization to leukocyte and platelet-bound alloantigens, or non-hemolytic transfusion reactions in already alloimmunized patients. Alloimmunization can be circumvened and effective long-term platelet support to thrombocytopenic patients can be provided by matching donor and recipient for HL-A antigens. The place of granulocyte transfusions in clinical therapy has yet to be defined, although their usefulness in infected granulocytopenic patients is suggested by the few studies reported so far.

    Notes: Summary The influence of prospective HLA-DR matching on the graft survival rate was investigated in a multicenter analysis of 85 transplants. Simultaneously in a retrospective analysis of graft outcome the importance of matching for MT-antigens MT1, MT2 and MT3 as a newly defined B-cell alloantigen system was evaluated. HLA-DR antigens and MT-specificities were determined on B-cells enriched by nylon-wool filtration using locally well characterised HLA-DR antisera and the antiserum set of the 8th International Histocompatibility Workshop (“discase set”) which allowed the definition of the HLA-DR specificities HLA-DR 1–9 and of the MT-antigens MT 1–3. HLA-DR matching showed a significantly improved graft outcome only in HLA-DR identical donor-recipient combinations. In 11 of 60 patients with one HLA-DR compatibility additional matching for two MT-antigens, however, improved the two year graft survival rate from 60% to 91%. Altogether 17 patients were matched for two MT-specificities with their kidney donor and showed a superior prognosis of 94% at two years compared to 53% or 17% of recipients with one or zero MT compatibility. Graft outcome in this patient group was also superior to that of HLA-DR identical or HLA-AB identical grafts. These data suggested that the MT-system rather than the HLA-DR antigens may be of critical importance in cadaver kidney transplantation. In addition a favorable influence of pretransplant blood transfusions on less HLA-DR matched grafts was confirmed.

    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: Abstract Three infants with severe combined immunodeficiency and adenosine deaminase (ADA) deficiency were treated by T-cell depleted bone marrow transplantation (BMT), using human leukocyte antigen (HLA)-haploidentical parents as donors. In the first patient, two initial transplants failed to engraft and no change of the immunodeficiency was observed. In order to overcome this graft resistance, cytoreductive conditioning was used prior to a third transplant. In the other two patients, similar conditioning was used prior to initial transplants. In all three patients, complete and permanent immunological reconstitution was observed and they survive from 3.5 to 5 years after transplantation. In biopsies obtained from iliac bones prior to BMT, osteochondral abnormalities characteristic of ADA-deficiency were noted in all three patients. After successful transplantation, these abnormalities had completely resolved. Our results demonstrate that cytoreductive conditioning prior to HLA-haploidentical BMT is useful in order to obtain stable engraftment and reversal of abnormalities associated with ADA deficiency.

    Notes: Summary Ten families with 82 members were investigated for C4A- and B polymorphism in a blind trial. Phenotyping was done on neuraminidase treated sera by immunofixation and simulataneously by hemolytic overlay electrophoresis. In addition Rg, Ch, BF, C2, HLA-A, B, C, DR, and GLO were determined. After decoding the samples the reliability of blind typing was found to be 84.4% according to segregation patters. Inconsistencies occurred mostly when A 4, A 2, or A 92 were present. The detection of silent A*Q0 and B*Q0 alleles was more critical than that of “difficult” allotypes. The quantitation of the C4A/B ratio by densitometry of stained gels or by conventional immunochemical measurements of serum C4 level could not substantially improve the identification of A*Q0 or B*Q0. C4 dependent activity in radial diffusion hemolysis showed satisfactory correspondence with the number of expressed C4B alleles. At least three haplotypes with two C4A genes (duplicated A genes) were observed as ascertained from offspring analysis in accordance with the MHC segregation pattern. Individuals with the duplicated C4A gene (C4A*3. A*2. in the absence of any other expressed A allele or together with C4A*92) showed only partial inhibition of Rodgers antisera. Partial inhibition of Chido antisera was seen in individuals with C4B 2 (in the absence of other B allotypes). The findings support the hypothesis of at least two structural C4 loci. The also demonstrate the inconsistency of quantitative data in the recognition of silent alleles.

    Notes: Summary The segregation of factor B(BF)F subtypes was analyzed in conjunction with other MHC markers in 15 families with 89 offspring. Informative data for BF F subtypes were obtained from 11 families, 6 of them with known recombinant individuals for the HLA-B/DR/GLO region. The subtypes did not contribute further to the localization of the cross-overs, but followed the known segregation of conventional BF allotypes. In 2 families of one kinship, the recognition of heterozygous BF*FAFB individuals could be established following the inclusion of three generations. The rarer of the two BF F subtype alleles, BF*FA, is positively associated with the HLA haplotypes BW62, CW3, C4A*3 and A29, CWX, B44, C4A*3, B*1, DR7. BF F subtypes are regarded as a very useful additional tool for studies of MHC organization and disease association.
