Sepsis is one of the important complications on the treatment of severe hematological diseases. In this report, we analyzed sepsis in 309 patients with hematological diseases who were admitted to the First Department of Internal Medicine of Yokohama City University Hospital from 1979 to 1986. Positive blood culture were found in 17.8% (55/309 cases) and total positive cases were 73 including recurrent patients. Positive rate by underlying diseases was 30.3% in acute leukemia, 20.8% in chronic myelocytic leukemia, 17.2% in aplastic anemia, 8.0% in multiple myeloma, 6.0% in malignant lymphoma and 6.5% in others. The organisms causing sepsis were as follows; gram negative bacilli 56.4%, gram positive organisms 34.6%, fungus 6.4% and anaerobic bacteria 2.6%. Pseudomonas aeruginosa was found in 19.2%. The mortality rate of patients with sepsis was 34.2% (25/73 cases). The significant prognostic factors in patients with sepsis were the degree of neutropenia, duration of neutropenia (500 less than microliters), the species of organisms, simultaneous complication with shock and the site of other infections.

Splenic erythropoiesis was demonstrated by surface counting of 59Fe in 129 of 1,350 ferrokinetic studies performed over a 15 year period. These 129 studies were carried out in 108 patients, including 40 with chronic myelogenous leukemia (CML), 24 with agnogenic myeloid metaplasia (AMM), 18 with polycythemia vera (PV), six with a myelodysplastic syndrome, five with acute leukemia, three with prostate or breast carcinoma, two each with aplastic anemia or Hodgkin's disease, and one each with idiopathic thrombocythemia, multiple myeloma, chronic renal failure, or treated hypopituitarism. Splenomegaly was present in 83% of the studies and hepatomegaly in 72%. Grade II-III myelofibrosis was demonstrated in 62% of the cases. Hepatic erythropoiesis was present in 77% of the studies (only 38% in PV), and marrow erythropoiesis was undetectable in 33%. Total erythropoiesis was about twice normal (range 0.2 to 8 times normal) but was ineffective to varying degrees in 86% of the studies. Relationships between organomegaly, myelofibrosis, and extramedullary erythropoiesis, as well as differences among clinical disorders, are discussed. Differences observed between CML in chronic or blastic phase suggested that the erythroid cell line was involved in the proliferative process. It is concluded that splenic erythropoiesis 1) is encountered in a variety of clinical conditions; 2) is not necessarily associated with splenomegaly or myelofibrosis, even in the myeloproliferative disorders; 3) is part of a predominantly extramedullary (in the liver as well as in the spleen), expanded, and largely inefficient total erythropoiesis; and 4) can be evaluated in a semiquantitative manner by surface counting.

The incidence and the outcome of cytomegalovirus (CMV) infections were evaluated in 83 adult recipients of allogenic bone marrow transplantation. Virological and serological surveillance was performed weekly for 3 months posttransplant, and then every other week or every month until 1 year. CMV infection occurred in 45 patients, with a cumulative risk of 62% at 1 year and 66% at 2 years. In multivariate analysis, two factors significantly influenced the incidence of CMV infection: patients with pretransplant positive anti-CMV titres had a risk of infection of 72% at 1 year versus 33% for patients with negative titres. Patients with acute myeloid leukemia were also infected more frequently (85% at 1 year) than patients with acute lymphoblastic leukemia (56%), chronic granulocytic leukemia (45%), or aplastic anemia (47%). In both univariate and multivariate analysis, CMV infection was not associated with a worse prognosis. However, 5 (out of 10) cases of lethal interstitial pneumonitis were associated with CMV, and two patients died of possible CMV encephalitis. All these patients had been suffering from severe acute or chronic graft versus host disease.

Between April 1982 and March 1983, 10 of 26 (38.4%) allogeneic bone marrow transplant recipients housed on a newly opened bone marrow transplant unit developed invasive aspergillosis. By contrast, between September 1977 and March 1982, only 3 of 46 (6%) transplant recipients developed invasive aspergillosis. A case-control study to identify host factors related to Aspergillus infection found that aspergillosis was more common in patients with chronic myelogenous leukemia and aplastic anemia, older patients, patients having cytomegalovirus disease, patients who experienced prolonged granulocytopenia, patients conditioned with ara-C (100-200 mg/day), and patients who received longer duration of antimicrobial therapy. A series of logistic regression analyses revealed that underlying disease was the single best predictor of Aspergillus infection. This study demonstrates that underlying disease is an important risk factor for aspergillosis and that special measures may be warranted when transplanting certain patients.

Ten children between the ages of five and fifteen years old with leukemia (two with acute nonlymphocytic leukemia in first remission, four with acute lymphocytic leukemia in first or second remission, one with acute lymphocytic leukemia in relapse, and one with chronic myelocytic leukemia in chronic phase), malignant lymphoma (one) or severe aplastic anemia (one) were given transplants from HLA-matched or mismatched family members between March, 1982 and April, 1984. Two patients died of leukemia relapses on days 107 and 257 following transplantation. One patient died of cardiac failure on day 157. One patient who received HLA-mismatched marrow from his father died of pulmonary edema and acute graft versus host disease on day 32. Six are alive 268-843 days post transplantation. None of the ten patients developed interstitial pneumonia due to cytomegalovirus which is one of the major causes of death reported in other published studies.

Bone marrow transplantation was performed between IV/82 and X/85 in 64 patients with acute leukemia (n = 36), chronic myelogenous leukemia (CML; n = 13), severe aplastic anemia (n = 12), and neuroblastoma stage IV (n = 3). Of these patients 57 received allogeneic marrow from HLA-ABCDR identical, MLC-negative sibling donors. Six transplants were performed with syngenic marrow and one with autologous marrow. Of the 64 patients 48 survived 40-1,250 days after transplantation, resulting in a survival rate (SR) of 75% and a survival probability (SP) of 71%. Of the 36 patients suffering from acute leukemia (SR = 64%, SP = 51%), patients with acute myelogenous leukemia (AML) in first complete remission (n = 11; SR = 81%, SP = 76%), as well as patients with acute lymphatic leukemia (ALL) in 1st to 4th complete remission at the time of transplantation (n = 14; SR = 81%, SP = 76%) show a favorable prognosis. A poor survival rate was seen for patients with AML when transplanted in second or partial remission (1/5; SR = 20%), as well as for patients suffering from ALL and transplanted during relapse or partial remission (1/6; SR = 16%). Of 13 patients suffering from CML 12 survived the transplantation free of relapse (SR = 93%, SP = 92%), and one patient died from varicella zoster pneumonia. Of the transplanted patients with severe aplastic anemia, 12 of 13 are surviving with complete hematologic reconstitution; one patient, however, died on day 10 from a sepsis. In our patient group, the SR as well as the SP has been improved through changes in the irradiation protocol concomitant with prophylactic application of anti-CMV hypergammaglobulin, as well as through additional oral medication of Azyklovir. The 41 patients (BMT No. 7-47) with total body irradiation at one time show an SR of 44% and an SP of 41%. The following 46 patients (BMT No. 48-93) have reached an SR of 83% and an SP of 74% under the regimen of fractionated total body irradiation, plus prophylaxis with anti-CMV hypergammaglobulin and Azyklovir. Within this group, no fatal CMV pneumonia was encountered as opposed to six patients lost from CMV pneumonia in the first group.

Determination of AK types in 372 patients of Hematologic Clinic, revealed in many cases changes in electrophoretic pattern of AK1 type namely the occurrence of an additional protein band. These changes were observed mostly in the acute granulocytic leukemia, lymphoblastic leukemia, and aplastic anemia. In the chronic granulocytic leukemia they were present as a rule, during the blastic crisis. Phenotypic changes were transient and the repeated examinations showed disappearance of an additional band in some patients. Etiology of the changes observed is still unclear.

Bone marrow transplantation is impossible without effective support with blood components during the period of pancytopenia before graft function appears. We analyzed 39 patients with leukemia and three patients with severe aplastic anemia with regard to the pre- and postgrafting requirements for RBC and PLT transfusions. Overall a median of eight RBC and four PLT concentrates were necessary in all 42 patients after allogeneic BMT (ranges, 1-32 RBC and 1-11 PLT units). Requirements were identical irrespective of the underlying disease (ALL, AML, CML, SAA). Transfusion need for RBC and PLT concentrates increased in patients over 30 years old and with a major red blood group AB0 barrier between marrow donor and recipient. The presence of grade II-IV GvHD increased RBC requirements significantly, but not PLT requirements. In addition these patients were dependent on RBC transfusions for significantly longer periods. Only one patient required therapeutic granulocyte transfusions. In a CMV-negative patient with a CMV-negative marrow donor, who died of veno-occlusive disease, cytomegalovirus was transmitted inadvertently by a seropositive PLT concentrate in his final course. Our transfusion strategy included frozen deglycerolized RBC concentrates and single donor PLT concentrates, collected mainly from the marrow donor by a cell separator. All blood products were irradiated in vitro with 1500 cGy before transfusion. An optimal transfusion policy starting before BMT can contribute to successful bone marrow transplantation.

From December 1975 until October 1988 292 bone marrow transplantations (bmt) have been performed at the Center for Tumor Research and Tumor Therapy, University Hospital Essen; 251 of these transplantations were allogeneic, 30 autologous and 11 syngeneic. The main indications were ALL (n = 39), AML (n = 132), CML (n = 75) and severe aplastic anemia (n = 26). Now the transplantation rate is one bmt per week. Early transplantation during a controlled stage of disease provides the best chance of cure. Important prerequisites of a successful allotransplantation are patient age under 45-50 years, good general condition and a histocompatible donor. In case of autologous bmt, being mainly tested in acute leukemias and malignant lymphomas, the age limit is 50-55 years. If the allogeneic transplantation is performed during an early stage of disease, the cure expectancy is about 50% for acute leukemia in first remission and CML in chronic phase. In the case of severe aplastic anemia the cure rates are even higher, provided that the transplant is grafted before multiple blood transfusions have been given. In AML the risk of relapse after autologous bmt is higher than after allogeneic transplantation, but the preliminary data are promising. The question of whether or not autologous bmt is superior to conventional chemotherapy of AML, has to be investigated.

481 cases of adult leukemia (115 acute lymphoblastic leukemia, ALL, and 366 acute nonlymphoid leukemia, ANLL) diagnosed at the Hematology Division of Pavia between 1976 and 1985 were reviewed to evaluate how many patients had an aplastic presentation. In 8 cases (1.6%) typical marrow hypoplasia preceded overt leukemia. At the leukemic transformation, the morphological and immunological findings were diagnostic for non-T non-B ALL in 2 cases, for ANLL in 5 cases (2 M1, 2 M2, 1 M5) and for Ph'-negative chronic granulocytic leukemia in 1 case. Median survival from the onset of leukemia was 5 months. In a certain proportion of cases aplastic anemia may be considered as a preleukemic state with a low propensity to develop into acute leukemia.
