The efficiency of stored platelet transfusion was evaluated in terms of clinical status in 141 thrombocytopenic patients. In a paired prospective study in which fresh platelets were used as controls, clinical efficiency was assessed on the basis of the ability to increase platelet count (recovery) and the time to the next transfusion (D). In 48 clinically stable patients, recovery of fresh and stored platelets was similar (47% and 41%, respectively) and the interval to the next transfusion was D4 and D3. In contrast, 27 patients who had bacterial infections showed significantly different recoveries (24%/5%) and the interval to the next transfusion was D3/D1 for fresh and stored platelets respectively. Similarly, in 16 patients who were treated concurrently with amphotericin B, 18 other patients with
graft-versus-host disease
, nine with splenomegaly and four with
veno-occlusive disease
(
VOD
), fresh platelets performed better than stored platelets, showing recoveries of 27%/18%, 29%/15%, 16%/3% and 15%/2%. Furthermore, the need for retransfusion within 24 h was significantly increased with stored platelets. In 19 patients with anti-HLA alloimmunization who were transfused with HLA-matched fresh and stored apheresis platelet concentrate (APC), efficiency was similar (38%/36% and D4/D3). This study indicates that the storage induces an impressive decrease in the in-vivo platelet recovery and survival in patients with certain clinical conditions.

Differential diagnosis of hepatic complications after bone marrow transplantation (BMT) is often difficult. To assess whether serum concentrations of the aminopropeptide of type III procollagen (PIIINP) could facilitate diagnosis, we measured serum PIIINP, corrected for age by conversion to standard deviation scores (SDS), serially after BMT in 27 children. A preliminary study of 11 patients showed that a PNIIINP-SDS cutoff of 8.0 was an optimum for diagnosis of
veno-occlusive disease
(
VOD
). PIIINP-SDS was increased above cut-off 1-25 days before the onset of clinical signs in the 12 patients (4 from the preliminary group, the others from a group of 16 studied prospectively) who developed
VOD
, with subsequent changes in PIIINP-SDS mirroring the course of
VOD
. By contrast, PIIINP-SDS remained below cut-off in all other patients, including 7 with liver
graft-versus-host disease
and 3 with drug hepatotoxicity. PIIINP-SDS values greater than 8.0 predict, diagnose, and monitor
VOD
after BMT.

Cytokine gene expression in peripheral blood mononuclear cells during the development of
graft-versus-host disease
(
GVHD
) in patients who underwent allogeneic bone marrow transplantation (allo BMT) was analysed using a semiquantitative reverse-transcriptase polymerase chain reaction (RT-PCR). The expression of interleukin (IL)-1 beta, IL-6, and tumour necrosis factor (TNF)-alpha mRNA was increased during the development of
GVHD
and the degree of this increment depended on the severity of the disease. IL-2 expression was not detected at all and interferon-gamma expression was not much changed during
GVHD
. In patients with hepatic veno-occlusive disease (
VOD
), another transplantation-related complication, the expression of IL-1 beta and TNF-alpha mRNA was increased but IL-6 mRNA expression showed little increase. These findings suggest that IL-1 beta, IL-6 and TNF-alpha produced by peripheral blood mononuclear cells play an important role in the development of
GVHD
. Furthermore, liver dysfunction due to
GVHD
or
VOD
may be distinguishable by this type of cytokine analysis. Analysis of cytokine mRNA expression in peripheral blood mononuclear cells after allogeneic bone marrow transplantation may provide important information concerning the immune response and the cytokine network system in marrow transplant patients.

In a retrospective multicentre study, we analyzed 184 consecutive patients who underwent bone marrow transplantation (BMT) from identical siblings for adult acute lymphoblastic leukemia in first complete remission between March 1980 and May 1989. The main causes of transplant-related mortality were
GVHD
and interstitial pneumonitis. Univariate and multivariate analyses identified the mode of total body irradiation (TBI) as the only independent predictive factor of transplant-related mortality. Ninety-one patients received single-dose TBI and 93 received fractionated-dose TBI as part of the conditioning regimen prior to BMT. Transplant-related mortality was more frequent in the single dose group (p = 0.017). The incidence of interstitial pneumonitis, acute and chronic
GVHD
and
veno-occlusive disease
of the liver was not statistically different between the two irradiation groups. However, fatal interstitial pneumonitis was significantly more frequent in the single dose irradiation group (p = 0.031). These results show that transplant-related mortality is closely associated with the mode of TBI administration. The increased relapse rate in the fractionated group explains why there was no difference between the two groups in terms of overall leukemia-free survival.

Case 1: A 26-year-old female was admitted because of leukocytosis with 43.6% myeloblasts and 33.6% monocytes, and trilineage myelodysplasia (T-MDS) was detected on bone marrow (BM) smear. She was diagnosed as having acute myeloid leukemia (AML) (M4) with T-MDS and was treated with the Japan Adult Leukemia Study Group (JALSG) AML87 protocol. After completion of chemotherapy, leukemic myeloblasts remained minimally and myelodysplastic changes were still detected on BM smear. She underwent allo-BMT from an HLA-identical sibling. The conditioning regimen consisted of busulfan and cyclophosphamide. Cyclosporine A and short term methotrexate were administered prophylactically for
graft-versus-host disease
(
GVHD
). She developed slight
veno-occlusive disease
and pancytopenia, which improved soon. She is surviving free of disease for 37 months from BMT. Case 2: A 41-year-old male was diagnosed as having T-MDS AML (M2) and achieved complete remission with the AML89 protocol, but relapsed soon. He underwent allo-BMT from an HLA-identical sibling. The conditioning regimen and prophylaxis against
GVHD
were the same as in case 1. He developed mild acute
GVHD
, pleural effusion and later mild chronic
GVHD
. These improved soon. He is surviving free of disease for 21 months from BMT. Some reports suggest that intensive chemotherapy can induce CR in 40%-70% of patients with T-MDS AML, but most of them tend to relapse and rarely survive long. We consider that the best strategy for treatment of T-MDS AML is allo-BMT at present, if suitable donors are available.

Patients receiving allogeneic bone marrow transplant experience multiple complications. Specifically, infection, renal complications,
VOD
, and
GVHD
can produce life-threatening toxicity. Many of the treatments cause further compromise of major organs. Astute nursing assessment and prompt interventions can decrease the severity experienced by the patient. Each of these complications requires ongoing study to develop new therapies for management.

Between October 1988 and December 1992, 167 patients with leukemia receiving marrow transplants from HLA-identical donors and conditioned with cyclophosphamide (120 mg/kg) were randomized to additional treatment with either busulfan (16 mg/kg, n = 88) or total body irradiation (TBI; n = 79). The busulfan-treated patients had an increased cumulative incidence of
veno-occlusive disease
of the liver, ie, 12% compared with 1% in the TBI group (P = .009). Furthermore, hemorrhagic cystitis occurred in 24% of the busulfan patients versus 8% in the TBI patients (P = .003). In patients with advanced disease beyond first remission or first chronic phase, transplantation-related mortality was 62% among the busulfan-treated patients compared with 12% among the TBI recipients (P = .002). These differences between the two groups were statistically significant in multivariate analysis. Seizures were seen in 6% of the busulfan-treated patients and were absent in the TBI group (P = .03). Grade II-IV of acute
graft-versus-host disease
(
GVHD
) was similar in the two groups, but grade III-IV and chronic disease was more common in the busulfan-treated group (P = .04). Death associated with
GVHD
occurred in 17% of the busulfan-treated group and 2% of the TBI group (P = .003). Patients treated with busulfan had a 3-year actuarial survival of 62%, which was worse than the 76% among those treated with TBI (P < .03). In multivariate analysis, poor survival was associated with advanced disease (P < .0001), no posttransplant septicemia (P = .0006), grade II-IV
GVHD
(P = .006), and busulfan treatment (P < .02). The incidence of relapse did not differ between the two groups. Relapse-free survival was also similar in the two treatment groups on analysis of data from all patients, children, patients with early disease, and those with acute myeloid leukemia, acute lymphoblastic leukemia, and chronic myeloid leukemia. However, in adults (P = .05) and patients with advanced disease (P = .005), leukemia-free survival was significantly better in those treated with TBI. We conclude that patients treated with busulfan have more early toxicity and an increased transplant-related mortality in patients with advanced disease. TBI is therefore the treatment of choice, especially in adults and patients with advanced disease. However, busulfan is an acceptable alternative for patients with early disease and for those in whom TBI is not feasible.

In 19 patients with anti-HLA allo-immunization who were transfused with HLA-matched fresh and stored APC, efficiency was similar (38%/36% and D4/D3). This study indicates that the storage has a major detrimental effect on platelet recovery and survival in patients with certain clinical conditions.

A 14-year-old girl with acute lymphoblastic leukemia in second remission received an allogeneic marrow graft from her HLA identical brother. Cyclosporine A and short term methotrexate were given for prophylaxis against
graft versus host disease
. On day 42 post transplantation elevation of SGOT and SGPT was recognized, rising the next day to 8,560IU and 2,590IU, respectively. Prothrombin activity dropped below 10%. HCV antibody and HBs antigen were both negative. Fulminant hepatitis was diagnosed, therefore plasma exchange was initiated. However, hepatic encephalopathy developed and she died on day 57. The postmortem liver appearance was consistent with early changes of
veno-occlusive disease
. Such atypical cases of
VOD
with late onset are difficult to distinguish from fulminant hepatitis but should be kept in mind.

We report the development of a double-cycle elutriation (DCE) technique separating 3 or greater logs of T cells from a stem-cell-enriched marrow fraction and the results of phase I T-cell depletion studies with HLA-disparate related bone marrow transplantation (BMT) donors in two patient groups. In group 1, 10 patients with refractory hematopoietic malignancies received combination chemotherapy, total body irradiation (TBI), and immunosuppression (pre- and post-BMT), and hematopoietic rescue with a marrow transplant, depleted of T cells by elutriation. Potentially to promote engraftment and a graft-versus-leukemia (GVL) effect, 0.5 to 0.75 x 10(5) T cells/kg were added back. All 10 patients engrafted. Five patients developed acute
graft-versus-host disease
(
GVHD
; four grade II, one grade III) and two subsequently developed chronic
GVHD
. Two patients have relapsed (median follow-up, 206 days; range, 46 to 1,035). Four patients died of BMT-related complications (three of infection, one of
veno-occlusive disease
[
VOD
]). Four patient are disease-free survivors (median follow-up, 960 days; range, 670 to 1,035). Group 2 included five infants, four with congenital lymphohematopoietic deficiencies and one with refractory acute lymphocytic leukemia (ALL). In these infants, busulfan and increased cyclophosphamide were substituted for TBI. Only the ALL patient received added T cells. Three patients engrafted: one has stable mixed chimerism, one relapsed with ALL, and one rejected the marrow. One patient had primary autologous recovery, while another failed to engraft. None developed
GVHD
. We conclude that, in this setting of HLA-disparate BMT with post-BMT antithymocyte globulin (ATG) and corticosteroids, DCE significantly depletes T cells from the marrow and that a defined number of T cells can be added without the occurrence of severe
GVHD
.
