An allogenic bone marrow transplantation (BMT) in an acute nonlymphocytic leukemia (ANLL) patient with post-transfusion hepatitis C is presented. A 13-year-old girl was admitted to our hospital on May 1988, and diagnosed as having ANLL M2 according to the FAB classification. During the induction and post-induction chemotherapy, 116 units of blood products were transfused to her as the supportive therapy until October 1988, when non-A non-B
hepatitis
developed. As the persistent liver dysfunction interfered with anti-leukemic chemotherapy on the protocol, allogeneic BMT from her HLA identical
MLR
nonreactive brother was done on July 1989. Preconditioning regimen consisted of busulfan and cyclophosphamide. GVHD prophylaxis consisted of cyclosporine A and short term methotrexate. After the BMT, her liver dysfunction once improved; her serum amino-transferase levels were normal for about 3 months. Soon after discontinuation of cyclosporine A, however, her liver function deteriorated again. The examination of hepatitis C virus antibody in her sera, which had been harvested sequentially and stored at -40 degrees C, on November 1989 revealed that she had been already seropositive at the time of BMT. The BMT-induced immunologic changes may have influenced the natural course of hepatitis C virus infection in the patient.

Two patients of acute myeloblastic leukemia (M2) with post-transfusional
hepatitis
(non-A, non-B) were treated with alpha-IFN and high-dose SNMC before allogeneic bone marrow transplantation. Bone marrow transplantation from HLA identical and
MLR
negative sibling donor was carried out when their hepatic functions were almost normalized. In the early phase after bone marrow transplantation, the hepatic function in both two cases has been stable, thus indicating that this treatment should be tried for reducing hepatic dysfunction and for safety bone marrow transplantation.

Cellular immune responses to hepatitis B virus (HBV) play an important role in the resolution of acute infection. They also influence the course of chronic infection and disease but are inadequate to completely clear the infection. Woodchuck
hepatitis
virus (WHV) infection of the woodchuck can provide a model to study these processes. Lymphocyte responses of woodchucks were assessed by in vitro proliferation and/or interleukin (IL)-2 assays using mitogen (Concanavalin A [ConA]), cytokine (IL-2), superantigen (Staphylococcus aureus enterotoxin B [SEB]), major histocompatibility complex (MHC) allo-antigen (mixed lymphocyte reaction [
MLR
]), and viral antigens (woodchuck
hepatitis
virus core antigen [WHcAg] and woodchuck
hepatitis
virus surface antigen [WHsAg]). ConA-stimulated woodchuck lymphocytes underwent cell division based on cell counting experiments and produced IL-2 as detected using an IL-2-dependent murine cell line but failed to incorporate sufficient tritiated thymidine; however, they did incorporate sufficient tritiated adenosine and deoxyadenosine to permit development of a meaningful proliferation assay. The IL-2 assay was sensitive and specific for detection of woodchuck IL-2 induced by mitogen, superantigen, and
MLR
, as shown by quantitative titration analysis and anti-body neutralization of ConA-supernatant activity. Cyclosporin A and FK506 specifically inhibited ConA- and SEB-induced IL-2 production by woodchuck lymphocytes. Positive two-way MLRs were detected by IL-2 production and proliferation assay between woodchucks from different geographic regions, thus indicating divergence among MHC molecules; however, occasional negative
MLR
reactions among indigenous pairs of woodchucks indicated that some woodchucks were mutually immunocompatible to some degree. The radioadenosine proliferation assay was sensitive for detecting peripheral blood lymphocyte responses to WHcAg and WHsAg in adult woodchucks with recently resolved acute infections. The above systems should facilitate the design of adoptive therapy and liver transplantation experiments in the woodchuck, and also enable modeling of immune responses that promote and maintain chronic hepadnavirus infection.

We analysed the use of allogeneic bone marrow transplantation (BMT) in the treatment of acute myelogenous leukemia (AML). We evaluated 271 adult patients with newly diagnosed AML treated here between 1983 and 1992; 113 patients (42%) were eligible for BMT because of their age (< 45 years until 1986 and < 50 years later). Of these, HLA typing was performed on 81 patients (72%); 32 patients were not typed (19 had no sibling, 8 had a primary refractory leukemia, 3 died during induction, 1 had important previous toxicity and for one patient there was no recorded reason). Of the 81 typed, 36 patients (44.4%) were found to have an HLA-matched sibling donor and 21 (25%) underwent BMT (8% of the total population); 15 patients did not undergo BMT (6 relapsed before transplantation and did not obtain a second remission, 3 declined the procedure, 1 died during induction, 1 had positive
MLR
, 1 had positive
MLR
and HCV
hepatitis
, 1 was a drug addict with HCV
hepatitis
, 1 had previous organ toxicity, 1 was psychotic). These data show that only a small fraction of unselected patients with AML can undergo BMT. Such findings make the comparison of BMT with other types of post-remission therapy more complex.
