RESUMO

Veno-occlusive disease (VOD) of the liver is a serious and often lethal sequela to bone marrow transplantation. Although a history of prior hepatitis moderately increases the risk of VOD, reliable screening methods for identifying high risk patients are not available. New approaches to managing patients who develop serious VOD are needed. One approach may be the use of orthotopic liver transplantation in selected patients who are likely to die of the disease. In this report we describe a patient who underwent liver transplantation for life-threatening VOD following allogeneic transplantation for CML. Although this patient died early from interstitial pneumonitis, the orthotopic liver functioned well up to her death. Other reports describing successful liver transplants in patients with advanced VOD or graft-versus-host disease of the liver are discussed and the possible indications for liver transplantation for VOD after marrow transplantation are considered. Taken together, these reports suggest that orthotopic liver transplantation may be a feasible and potentially effective approach to managing select patients with life-threatening liver dysfunction after marrow transplantation.

RESUMO

Patients with acute myeloid leukaemia who fail to show substantial bone marrow cytoreduction by day 6 of induction therapy enter complete remission (CR) less frequently than patients with good bone marrow leukaemic cytoreduction. The objective of the current study was to determine whether an increase in the intensity of therapy on days 8, 9 and 10 ('augmentation' of remission induction therapy) for patients with poor bone marrow cytoreduction detected in the day 6 bone marrow could improve the complete remission rate without increasing the number of toxic deaths. Patients from six centres were entered and treated with standard dose ara-C for 7 or 10 d and an anthracycline for the first 3 d. Patients aged less than 60 years and with greater than 30% bone marrow biopsy cellularity or greater than 10% abnormal cells on the aspirate obtained 6 d after the start of therapy were augmented with cytosine arabinoside 3 g/m2 every 12 h on days 8, 9 and 10. Therapy was augmented in 116 of the 252 patients less than 60 years. There was a highly statistically significant difference between augmented and nonaugmented patients (P less than 0.001) for the per cent biopsy cellularity and per cent abnormal cells in the day 6 marrow. The CR rate for augmented patients was 69% and for nonaugmented patients 60% suggesting that augmentation therapy abrogated the prognostic significance of more extensive residual leukaemia in the day 6 bone marrow. The results suggest that augmentation of remission induction for patients with poor bone marrow cytoreduction detected 6 d after initiation of therapy, may salvage patients who are destined to fail remission induction because of resistant disease without producing excessive toxicity.

RESUMO

Sixty-seven patients with newly diagnosed acute nonlymphocytic leukemia (ANLL) who were considered to be poor candidates for treatment with cytosine arabinoside (ara-C)/anthracycline antibiotic therapy were treated with high-dose ara-C (HDara-C) remission induction therapy. Thirty-four of the 67 patients had a hematologic disorder before developing acute leukemia or had a history of exposure to marrow toxins, 23 patients were greater than 70 years old, and 10 patients had medical problems that were felt to be a contraindication to therapy with an anthracycline antibiotic. Forty-two percent of patients entered complete remission (CR), whereas 22% failed to enter remission because of persistent leukemia. Treatment was associated with substantial toxicity varying from nausea and vomiting to irreversible cerebellar toxicity. Thirty-four percent of patients died during therapy. Poor performance status, a low serum albumin, and a low platelet count were associated with death during remission induction therapy, whereas a high pretherapy leukemic cell mass and a large number of residual leukemic cells in the marrow after six days of therapy were associated with treatment failure due to persistent leukemia.

RESUMO

The presence of teardrop-shaped red cells in peripheral blood has traditionally been felt to reflect altered marrow architecture, namely myelofibrosis. We evaluated two patients with splenomegaly, moderately severe hemolytic anemia due to warm-reactive IgG anti-red cell autoantibody, and bone marrow erythroid hyperplasia without myelofibrosis. A striking predominance of teardrop-shaped red cells was noted upon examination of their blood films. Removal of a spleen containing extramedullary hematopoiesis in one and resolution of splenomegaly in the other were accompanied by disappearance of these cells. Our observations support a role for the spleen and for extramedullary hematopoiesis in the pathogenesis of this distinctive red cell morphologic abnormality.
