Prognosis of second marrow transplantation after leukemia relapse is usually gloomy. We report a patient with AML who was successfully treated by the second marrow transplant following high dose busulfan, etoposide, and Ara-C for the testicular relapse after the first marrow transplantation. A 24-year-old man was diagnosed as having acute myeloid leukemia (AML) in September, 1988. In December of 1989 when he was in early relapse after his 2nd remission, he received the first allogeneic BMT from his HLA identical brother after high dose busulfan and cyclophosphamide conditioning. His posttransplant course was uneventful and graft versus host disease was not observed. Three months after BMT, he noticed swelling on right testicle. Leukemic cell infiltration was confirmed by aspiration cytology. The testicular relapse was followed by marrow relapse. After successful remission induction chemotherapy, he received 17.5 Gy testicular irradiation and second marrow transplantation using high dose busulfan, etoposide, and Ara-C conditioning. Although his posttransplant period was complicated by severe mucositis, high fever and bronchopneumonia, hematologic recovery was obtained by 3 weeks after the second transplant. He is now continuing in complete remission 18 months after the second BMT. This case report suggests that the combination of high dose busulfan, etoposide, and Ara-C could be a choice as a conditioning regimen for resistant AML relapsing after BMT.

A twenty-four-year-old male patient with stage III advanced extragonadal germ-cell tumor obtained complete remission after comprehensive treatment including high-dose combination chemotherapy with autologous bone marrow transplantation. He had massive tumors in cervical, mediastinal, abdominal and inguinal lymph nodes, bilateral lungs and liver. Ascites, plural effusion and pericardial effusion were also noted. Cancer cells were demonstrated from his bloody sputum, pericardial drainage and an aspirate from supraclavicular tumor. His tumor produced hCG, AFP, placental ALP and LDH, and hCG was the best marker for the diagnosis and monitoring. The initial serum hCG level was high at 460,000 mIU/ml, but fell to 13 mIU/ml after 3 courses of PVP therapy. However, it rose ten-fold in a week. After ultra-high dose combination chemotherapy with autologous BMT, the patient's hCG fell to 1.8 mIU/ml and remained at that level thereafter. He has remained well with no sign of recurrence after 25 months.

A case of fulminant rhabdomyolysis occurring 4 months after allogeneic BMT for CML is reported. The patient developed rhabdomyolysis following the empiric institution of antibacterial and anti-tuberculous medication. His inpatient course was complicated by the development of acute anuric renal failure and a severe myopathy. With aggressive supportive care, both of these complications resolved, making this patient the only reported survivor of rhabdomyolysis occurring after BMT.

Ganciclovir is widely used as prophylactic and pre-emptive therapy, as well as treatment, for CMV infection following BMT. We report a case treated with ganciclovir 5 days a week. Following escalation of the ganciclovir dose to a twice daily dose to treat CMV antigenaemia, he developed encephalopathy. His encephalopathy resolved with withdrawal of ganciclovir. Ganciclovir encephalopathy has been described in other groups of patients but has not been reported following BMT to date. With its widespread use this complication is likely to be seen more often.

A 13-year-old splenectomized, multitransfused beta-thalassemia major, male patient received an allogenic BMT from his HLA-compatible brother after suffering grade III regimen-related pulmonary toxicity. He developed features of CMV pneumonitis with positive pp65 CMV antigenemia involving 2.5% peripheral blood neutrophils from day +46. The patient received intravenous immunoglobulin and ganciclovir 5 mg/kg intravenously twice daily. His neutrophil count was maintained above 1 x 10(9)/l by G-CSF 5 microg/kg subcutaneously as and when required. From day 7 onwards following twice daily ganciclovir his peripheral blood smear started showing isolated cytoplasmic inclusions, 1-3 per neutrophil, 3-5 mu in diameter, involving 2-3% of the neutrophils and occasional monocytes. Transmission election microscopy of peripheral blood neutrophils showed type I and type II intranuclear inclusions. These inclusions disappeared within 48 h of stopping ganciclovir. Inclusions were not seen in three patients who were given prophylactic ganciclovir 5 mg/kg once daily for 5 days every week following allogenic BMT after the same conditioning regimen. These patients were also negative for CMV antigenemia. Development of type I and type II intranuclear inclusions in blood neutrophils in patients receiving ganciclovir therapy has not been reported previously, and the striking light microscopic changes provide simple morphological evidence of the toxic effect of this drug on blood neutrophils.

We describe two patients who developed respiratory syncytial virus (RSV) pneumonia after BMT. One died of RSV pneumonia after three courses of steroid pulse therapy. Surprisingly, RSV antigen was identified in the bronchoalveolar lavage fluid (BALF) obtained post mortem. Steroid pulse therapy might have suppressed anti-RSV immunity, leading to persistent RSV infection for more than 1 month. The other patient received donor lymphocyte infusions (DLI) for relapsed plasma cell leukemia, while having active RSV pneumonia. His respiratory condition improved after DLI, and RSV antigen disappeared in BALF and nasal swabs. DLI might be effective in cases of life-threatening RSV pneumonia.

Severe aplastic anemia (SAA) is well described in children following liver transplantation for fulminant hepatic failure (FHF) secondary to non-A, non-B, non-C hepatitis, and is associated with a high mortality rate. Successful immunosuppressive treatment of SAA following liver transplantation has been reported, but death from infectious complications is not uncommon. We report the 8-year follow-up of a 3.5-year-old boy who underwent successful HLA-identical sibling donor bone marrow transplant for SAA 7 months following orthotopic liver transplant for non-A, non-B, non-C hepatitis. His post-bone marrow transplantation course was uneventful with no evidence of liver toxicity. Eight months following BMT he developed renal cell carcinoma metastatic to lymph nodes which was treated surgically. Six years following BMT he developed a mucoepidermoid carcinoma of the parotid gland also treated surgically. Despite these malignancies, he is currently well 8 years following liver and bone marrow transplantation, without signs of GVHD, growth failure or liver graft rejection. This is the first report of long-term follow-up of bone marrow transplantation for SAA following liver transplantation. The occurrence of two subsequent malignancies in this child underscores the need for close follow-up of future similar cases.

ABO incompatibility in allogeneic bone marrow transplantation may be associated with incomplete or delayed erythroid engraftment, being pure red cell aplasia (PRCA) the most severe complication in this setting. Attempts for the treatment of PRCA have been made with erythropoietin or with plasmapheresis with relative success, and some authors have reported the reversibility of PRCA with antilymphocyte globulin (ALG or ATG), based on the assumption that PRCA might be immunologically mediated. We report herewith a patient with acute leukemia who developed post--BMT pure red cell aplasia. His sibling donor (sister) was HLA identical and ABO incompatible, having low agglutinin titers against donor's blood group. PRCA did not improve after treatment with erythropoietin or a boost of hematopoietic progenitor cells obtained from donor's peripheral blood but the problem was resolved completely after treatment with ALG.

We reported a case of adolescent type adrenoleukodystrophy. A 20-year old man noticed slight hemiparesis on his right side. After admission, high level of serum VCLFA and ACTH and a point mutation in ALDP codon 606 were recognized along with white matter lesions in the left medulla, basal ganglia, splenium of the corpus callosum on brain MRI. Then we diagnosed the patient as having adolescent type adrenoleukodystrophy. We started Lorenzo's oil and seaching for BMT donor. Six months later, he received allo-BMT at our hospital. His clinical symptoms gradually deteriorated during waiting allo-BMT, and just before allo-BMT, right hemiparesis, gait disturbance, exaggerated deep tendon reflexes on his right side, right lower quadrantanopia and mild cognitive deterioration. Two months after allo-BMT, gait disturbance and right hemiparesis were alleviated. We also observed improvement of abnormal findings on brain MRI and magnetic stimulation. We believed that allo-BMT is effective for the treatment of adolescent type adrenoleukodystrophy.

Under immunosuppressive conditions after hematopoietic stem cell transplantation (HSCT), even if hepatitis B virus (HBV) antigen is negative but hepatitis B surface antibody (HBsAb) or hepatitis B core antibody (HBcAb) is presented, HBV reactivates and sometimes causes fulminant hepatitis. However, it remains unclear which patients will develop fulminant hepatitis, or whether fulminant hepatitis is caused by host-related factors or by virus-related factors. A 30-yr-old man with a history of aplastic anemia since 3 yr of age underwent allogenic BMT, when HBsAb and HBcAb were positive but HBs antigen (HBsAg) was negative. The donor was negative for HBsAg, HBsAb and HBcAb. After transplantation, the patient was complicated by acute graft-vs.-host disease (GVHD), cytomegalovirus infection, intestinal thrombotic microangiopathy and aspergillus colitis. Chronic GVHD was well controlled by FK506 and prednisolone. Twenty months after transplantation, the patient was admitted with general fatigue and liver dysfunction and was found to be positive for HBsAg and HBeAg. His serum HBV-DNA level was >8.8 log of the genome equivalent (LGE)/mL. Therefore, he was diagnosed as having hepatitis B caused by HBV reactivation and 100 mg/d lamivudine treatment was started. However, jaundice and hepatic failure deteriorated and became fatal. On analysis of the HBV-DNA, two adjacent gene mutations in the core promoter region (T1762/A1764) were detected. Increased replication of the mutated HBV might have caused HBV reactivation which progressed to fulminant hepatitis.
