    Description / Table of Contents: Summary Peripheral blood lymphocytes from 32 patients with defined paraproteinaemia (16 IgG, 9 IgA and 7 IgM) and from 15 healthy donors were studied for their in vitro response to various stimuli, including unspecific mitogens such asPhytohaemagglutinin (PHA),Pokeweedmitogen (PWM) and Concanavalin A (ConA) as well as specific antigens such as purified Tuberculin, Candida, Varidase, Tetanus Toxoid, Vaccinia antigen and Vaccinia-control antigen. Mitogens and antigens were lyophilized in Microtiter plates. The lymphocytes of all tested patient-groups responded (measured by H3-Thymidin-up-take) significantly lower towards the unspecific mitogens than those of the control group. If the patients' lymphocytes were stimulated by the specific antigens, their in vitro response was significantly diminished to candida and vaccinia. Macroglobulinaemia showed significantly lower response to ConA if compared to myelomas of IgG- and IgA-type. No correlation was found between mitogen and antigen response and the serum concentration of the paraproteins or immunoglobulins. The results show that monoclonal gammopathy and especially macroglobulinaemia are associated with abnormalities of the cellular immunity which correlates with the clinical observation of increased fungal and viral infections.
    Notes: Zusammenfassung Periphere Lymphozyten von 32 Patienten mit monoclonaler Gammopathie (16 IgG, 9 IgA and 7 IgM) und von 15 gesunden Spendern wurden hinsichtlich ihrer in vitro-Antwort auf folgende Stimuli untersucht: unspezifische Mitogene wiePhytohämagglutinin (PHA),PokeweedMitogen (PWM) andConcanavalinA (COnA), sowie die spezifischen Antigene Tuberkulin, Candida, Varidase, Tetanus Toxoid, Vaccinia-Antigen and Vaccinia-Kontroll-Antigen. Mitogene und Antigene wurden in lyophilisierter Form in Microtiter-Platten benützt. Die Lymphozyten aller getesteten Patienten-Gruppen antworteten signifikant niedriger auf Mitogenstimulation (gemessen am H3-Thymidin-Einbau) als diejenigen der Kontrollgruppe. Wenn die Patientenlymphozyten mit spezifischen Antigenen stimuliert wurden, ergab sich eine signifikant erniedrigte Antwort auf Candida- und Vaccinia-Antigen. Es zeigte sich eine signifikant erniedrigte Antwort auf ConA-Stimulation in Makroglobulinämie im Vergleich mit den Myelomen vom IgG-und IgA-Typ. Es bestand keine Korrelation zwischen Mitogen- oder Antigen-Antwort und der Serumkonzentration der Paraproteine oder polyclonalen Immunglobuline. Die Resultate zeigen, daß monoclonale Gammopathien, und hier besonders IgM-Paraproteinämien, mit einer gestörten zellulären Immunfunktion einhergehen, was mit der klinischen Beobachtung gehäufter viraler und fungaler Infektionen übereinstimmt.

    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 Twenty-one patients with chronic granulocytic leukaemia underwent marrow transplantation. The donors were human-lymphocyte antigen-identical siblings in 19 cases. In the remaining 2 cases the donor was a parent in one and an identical twin in the other. The preparatory regimen included cyclophosphamide and 8.6 Gy total body irradiation given at either a dose of 0.1 Gy/min or 0.04 Gy/min. Five patients were in the accelerated phase of the disease, one was in remission following blast crisis, and the rest were all in the chronic phase. After chemotherapy and irradiation, all patients received bone marrow transplants. To date, nine patients are still alive, with a median survival of 64 days (range 28–683 days). One patient continued to have leukaemic cells and in another, the leukaemia recurred 18 months following transplantation. Interstitial pneumonitis was the cause of death of eight patients (38%). Graft-versus-host disease occurred in ten patients (47%).

    Notes: Summary In a 45-year-old woman with severe normochromic anemia (Hb 2.8 g%) an extensive myelofibrosis and infiltration of the bone marrow with small blasts was observed histologically. Cytochemical examination of the blasts showed a negative peroxidase and a strongly positive alpha-NE reaction. PAS reaction was slightly granular positive in the cytoplasmic protuberances of the blasts and in the platelets. Marker analysis yielded no evidence of lymphatic origin of the blasts. In flow-cytometric studies of 230,000 cells a homogeneous 2c blast population could be identified. Cytogenetic analysis revealed an abnormal pseudo-diploid karyotype characterized by 2 acrocentric marker chromosomes caused by a translocation of chromosomes 8 and 14, as usually seen in Burkitt type lymphoma. Finally the reaction product of platelet-specific peroxidase could be demonstrated in the perinuclear cisternae of the endoplasmic reticulum by electron microscopy. Highly elevated β-thromboglobulin and platelet factor 4 plasma levels were also measured. Following an ineffective treatment with daunoblastine and ARA-C, the patient died of pseudomonas aeruginosa septicemia after having received high-dose ARA-C treatment.

    Notes: Summary In 23 children with mild iron-deficiency anemia, 22 children with latent iron-deficiency, and in 46 healthy controls the3H-thymidine incorporation in blood lymphocytes after stimulation with phytohemagglutinin, concanavalin A, pokeweed mitogen, and serum against thymocytic cells was measured. In 11 of the children with iron-deficiency anemia, in 13 of the children with latent iron-deficiency, and in 20 controls the lymphotoxin secretion after phytohemagglutinin stimulation was also performed. All patients studied were without intercurrent infections and were well nourished. No alteration of the lymphocyte function in the patients was found. The concentrations of immunoglobulins and the components C3 and C4 of complement system were also found to be normal. It is suggested that lymphocyte functions are eventually only altered in more severe states of iron-deficiency anemia.

    Notes: Abstract Multiple sclerosis patients-111 of them-were typed for theHLA-D allelesw1, w2, andw3 and a new determinant, EI. Statistically significant increase was obtained for thew2 andw3 frequencies as compared to healthy controls. The distribution of HLA-D phenotypes among MS patients revealed a good fit according to the Hardy-Weinberg law. By calculating linkage disequilibrium parameters, theHLA-B7,Dw2 allele combination was found to be more closely associated than in normal controls, whereas forHLA-Bw35, Dw1, no linkage disequilibrium could be detected in the patients' group. From these data we conclude that in multiple sclerosis, the disturbance affects the frequency ofDw3 and the gametic association between alleles of theHLA-B andD loci, as well as the already known increase ofHLA-B7 andDw2.

    Notes: Abstract A linkage between C2 deficiency and the HLA-A10,B18/BfS antigens has been found in a French family from the Strasbourg area. The propositus, suffering from a chronic glomerulonephritis, is homozygous forHLA-A10,B18/BfS and totally C2-deficient. The parents and the brother are heterozygous for C2 deficiency and share theHLA-A10,B18/BfS haplotype. MLC tests and HLA-D typing revealed that the homozygous C2-deficient patient is also homozygous at theHLA-D locus for the w2 specificity. Evidence was obtained for a heterogeneity of the HLA-Dw2 specificity. This observation confirms the remarkable association between C2 deficiency and theHLA-A10,B18,Dw2 haplotype.

    Notes: Zusammenfassung Die Verwendung des Kulturverfahrens zur Aufdeckung der Gonorrhöe in der Praxis ist notwendig. Ein hierfür geeignetes Verfahren muß ohne bakteriologische Hilfsmittel, Kenntnisse und Erfahrung für den Praktiker durchführbar sein. Wir konnten zeigen, daß die Dauer der Erhaltung der Wachstumsfähigkeit der Gonokokken mit steigender Temperatur abnimmt, und daß die Gonokokken in nährstofffreien Lösungen bei Temperaturen von −3° bis 5° bis zu 6 Tagen wachstumsfähig bleiben. Dies letztere hat seinen Grund in der Entwicklungshemmung der Gonokokken durch niedrige Temperaturen (−3° bis 5°). Diese Ergebnisse führten zur Entwicklung des „Kaltbewahrungsverfahrens”: Sekretentnahme mit feuchtem (Aqua dest., physiologische Kochsalzlösung) Watte-Holztupfer; Einbringung des beschickten Watte-Holztupfers in ein durch Korken verschließbares und am Boden mit feuchtem Wattebausch versehenes Reagensglas; Versendung in eisgefüllter Thermosflasche an ein geeignetes Laboratorium zur Überimpfung auf D-Platte. Mit Hilfe dieses „Kaltbewahrungsverfahrens” konnten von sicher positiven Sekreten (mikroskopisch oder kulturell gesichert) 92,5% als positiv erfaßt werden. Unter den Bedingungen der Praxis verhalten sich die durch die mikroskopische Untersuchung aufgedeckten positiven Befunde zu denen durch das „Kaltbewahrungsverfahren” ermittelten wie 14∶49! Das „Kaltbewahrungsverfahren” ist also geeignet, auch immer dann, wenn die Anlegung einer Sofortkultur nicht möglich ist, ohne Schwierigkeiten die Vorzüge der kulturellen Sicherung zu verwerten. Die Vorweisung eines geeigneten Versandtgefäßes glauben wir in Aussicht stellen zu können.
