To determine whether allogeneic bone-marrow transplantation is associated with a graft-versus-leukemia effect, we examined the relation between relapse of leukemia and graft-versus-host disease in 46 recipients of identical-twin (syngeneic) marrow, 117 recipients of HLA-identical-sibling (allogeneic) marrow with no or minimal graft-versus-host disease, and 79 recipients of allogeneic marrow with moderate to severe or chronic disease. The relative relapse rate was 2.5 times less in allogeneic-marrow recipients with graft-versus-host disease than in recipients without it (P less than 0.01). This apparent antileukemic effect was more marked in patients with lymphoblastic than nonlymphoblastic leukemia, and in those who received transplants during relapse rather than during remission, and was most evident during the first 130 days after transplantation. Survival of all patients was comparable since the lesser probability of recurrent leukemia in patients with graft-versus-host disease was offset by a greater probability of other causes of death.

A total of 29 cases of perirectal abscess at Milwaukee Children's Hospital between 1965 and 1975 were retrospectively reviewed. One fourth of these children had a serious underlying chronic disease. Staphylococcus aureaus was the organism that grew most frequently from pus obtained from the abscesses, accounting for 52% of the isolates. Therapy included incision and drainage alone and incision and drainage plus parenteral and/or oral antibiotic treatment. One patient, a child with leukemia, died of this infection. Complications, primarily fistulain-ano or recurrent abscess, occurred in 42% of the survivors.

Five patients with an unusual encephalopathy, possible secondary to measles virus infection, are described. Features common to these patients are: an existing chronic disease, neurologic deterioration 2 1/2 to 6 months after a measles infection, and death several weeks later. These events occurred when the chronic disease (e.g. leukemia or neuroblastoma) was in remission. That the measles virus was the causative agent is suggested only by finding in brain and extracranial tissues intracytoplasmic and intranuclear inclusions which contained measleslike particles. Additional clinical features seen in each of the five patients were: seizures, hypertension, and the inappropriate secretion of antidiuretic hormone.

The syndrome of CD8 hyperlymphocytosis with neutropenia is a heterogeneous disorder ranging from reactive benign state to neoplastic pathology. The prognosis for LGL (Large Granular Lymphocyte) leukemia depends likely on its phenotype:-NK phenotype, extremely poor prognosis and rapidly fatal-T phenotype (CD8+), chronic disease with slow progression. Here, we report four cases of CD8+ hyperlymphocytosis with neutropenia, which are CD2+/-, CD3+, CD4-, CD8+, CD16-, CD56+/-, CD57+ phenotype. These lymphocytic proliferations were associated with clonal rearrangement of T-cell receptor b gene. In two cases, characteristic blood hyperlymphocytosis appeared only after splenectomy, but retrospective bone marrow analysis showed that the CD8+, CD57+ lymphocyte proliferation previously existed. These lymphocytes had a low natural killer activity against K562 cell line. HTLV1 proviral sequence was not integrated in leukemic cell DNA. This monoclonal pathology has a chronic clinical course, with a thirteen year evolution in one case. Splenectomy did not correct neutropenia but allowed the control of hemolytic anemia and auto-immune thrombocytopenia in one case.

The first allogenic bone marrow transplantation (TKD), when for the preparation whole body irradiation was used, was implemented in the Institute of Haematology and Blood Transfusion (UHKT) in Prague in 1986. Before June 1992 36 TKD were performed incl. 28 allogenic, 2 syngenic and 6 autologous. For the first time bone marrow from a non-related donor was transplanted. Of 30 allogenic and syngenic TKD to the present time 17 patients survive, i.e. 56.6% of the whole group. According to individual diagnoses 8 patients with the diagnosis of chronic myeloid leukaemia (CML) survive, 5 of 10 patients with the diagnosis of acute leukaemia (AL) and 3 of 4 patients with the diagnosis of severe aplastic anaemia (SAA) or with Fancon's anaemia (FA) resp. The survival period of the whole group is from 1-62 months since the transplantation. The main cause of death of 8 from 13 patients who died were infections associated with acute or chronic disease of the graft against the host (GVHD). In autologous TKD the bone marrow was treated with etoposide. Of the six transplanted patients with AL five survive 1.5-30 months after transplantation. The authors present some general information of pretransplantation preparation, prevention of GVHD, its incidence and results of TKD.

Investigated age and gender differences in adjustment to chronic disease in children suffering from one of five conditions: diabetes, asthma, cardiac disease, epilepsy, and leukemia. Ratings of adjustment and disease-related restrictions were obtained separately from mothers and fathers. Factor analysis of the adjustment scale yielded 6 subscales which differentiated between children in terms of age and disease type, and to a lesser extent, gender. Mothers' and fathers' ratings of adjustment and restrictions were comparable, though fathers made less differentiation on the basis of disease or age. For both parents, perceived restrictions of the disease were associated with poorer adjustment in the child, and this was particularly reflected on indices of peer relations and work.

We recently showed that hemopoietic stem cells expressing the v-abl oncogene can cause leukemia when injected into lethally irradiated recipient mice. Progenitor cells expressing v-abl did not significantly contribute to disease development, and the leukemia was monoclonal in origin. By serially transplanting v-abl-transduced hemopoietic stem cells into normal, nonirradiated syngeneic recipients, we showed that multiple stem-cell clones do exist in some recipients. These cells fluctuated as normal stem cells do and could home to normal bone marrow. Based on the time course of disease, the recipients developed either an acute or a chronic phase of disorder. All recipients with the acute disease had stem-cell clones with random Abelson murine leukemia virus integration sites. All recipients with the chronic disorder had a specific Abelson murine leukemia virus integration site. We believe this abl-specific integration site, termed ASI, is important in abl-mediated stem-cell leukemogenesis.

Platelet function and the clinical course of the disease were prospectively investigated in 29 patients with myeloproliferative disorders. Serial determinations (median: 5 investigations per patient within 17 months) of platelet aggregation, plasma and intraplatelet concentrations of beta-thromboglobulin (beta TG) and platelet factor 4 (PF4), and of fibrinopeptide A (FPA) plasma levels were carried out. In the chronic phase of polycythaemia vera, patients with thrombohaemorrhagic complications during the study period had higher platelet count, more severe platelet aggregation defects, and increased plasma levels of beta TG and FPA compared to patients without complications. However, thrombohaemorrhagic complications were not predicted by changes in these parameters in the individual patient during the chronic disease phase. When patients with chronic myelogenous leukaemia entered blast crisis, bleeding complications were related to thrombocytopenia, impaired platelet function and low intraplatelet concentrations of beta TG and PF4. Cytoreduction by chemotherapy in the chronic phase of CML did not alter beta TG and PF4 plasma levels, whereas treatment of polycythaemia rubra vera by venesection favourably influenced platelet alpha-granule secretion and increased intraplatelet concentrations of beta TG and PF4.

There is a growing interest in the emotional status of parents and siblings after the death of a child with chronic disease. For the past 7 years physicians at our center have systematically contacted parents who lost a child because of leukemia within the first few months after the death. From this experience it appears that most parents needed to talk at least once with the physicians who took care of their child. As expected, some parents and siblings were found to have significant psychological problems and to need psychologic support. We suggest that the opportunity to talk with a physician of the attending staff should be provided routinely to parents shortly after the death of a child from leukemia.

Chronic myelogenous leukemia (CML) cell growth may be inhibited by exposure to antisense (AS) oligodeoxynucleotides (ODN). Our initial studies targeted the c-myb protooncogene and were carried out on cells derived from patients in CML blast crisis. Subsequently, we extended these studies to cells isolated from patients in chronic disease phase. We found that c-myb AS ODN inhibited growth of CML CFU-GM in a dose dependent, sequence specific manner in approximately 75% of cases evaluated. Bcr-abl expression was either greatly decreased or nondetectable in the residual colonies and no residual leukemic CFU were demonstrable upon re-plating of treated cells. AS ODN that target the c-kit protooncogene also inhibit CML CFU and lead to downregulation of bcr-abl in responding cells in approximately 50% of cases. Therefore, AS ODN may prove to be useful purging agents. Most recently, we have treated SCID mice engrafted with bcr-abl expressing human K562 cell leukemia with phosphorothioate modified AS ODN. We have found that treated mice survive three to eight times longer than their untreated or sense treated controls. In aggregate, these results suggest that AS ODN may prove useful for both ex vivo and in vivo treatment of patients with CML.
