Abstract
Platelet recovery after allogeneic haemopoietic stem cell transplant (HSCT) and predictive factors were analysed in 342 patients with haematological malignancies. All patients were prepared with cyclophosphamide plus total body irradiation, and received an unmanipulated HSCT from an HLA-identical sibling (n = 270), a matched unrelated donor (n = 67) or an identical twin (n = 5). The source of stem cells was peripheral blood (n = 15) or bone marrow (n = 327). Graft-vs.-host disease (GvHD) prophylaxis consisted of cyclosporin A with or without methotrexate. The proportion of patients with < 50 x 10(9)/l platelets on d +50, d +100, d +200 and d +365 after HSCT was 26%, 27%, 14% and 11% respectively. Thrombocytopenia was independent of the degree of complete donor chimaerism. Four variables were predictive of platelet recovery: donor type, acute GvHD, cytomegalovirus (CMV) infection and number of cells infused at transplant. Recipients of an unrelated graft had lower platelet counts (49 x 10(9)/l) on d +50 than identical sibling grafts (10(8) x 10(9)/l) (P < 0.001) and twin grafts (149 x 10(9)/l) (P < 0.001). Patients with GvHD grades 0, I, II, III and IV had significantly different platelet counts on d +50 (153 x 10(9)/l, 102 x 10(9)/l, 85 x 10(9)/l, 32 x 10(9)/l and 22 x 10(9)/l; P < 0.001) and thereafter. Thrombocytopenia was more frequent in patients with high-level CMV antigenaemia (> four positive cells/2 x 105) (P < 0.0001) and in patients who received a low cell dose at transplant (< or = 4.1 x 10(8)/kg) (P = 0.009). Platelet counts predicted transplant-related mortality (TRM) and were higher at all time intervals in patients surviving the transplant. Patients with grade II GvHD and > 50 x 10(9)/l platelets had a lower TRM than patients with grade II GvHD and < or = 50 x 10(9)/l platelets (14% vs. 40%, P < 0.0001). In conclusion, (i) a significant proportion of allogeneic HSCT recipients are thrombocytopenic long-term, irrespective of complete donor chimaerism, (ii) thrombocytopenia identifies patients at greater risk of lethal complications, and (iii) platelet recovery is influenced by GvHD, donor type, CMV infections and cell dose, not by stem cell source or other patient-disease-related variables.

Abstract
Preparative regimens without total body irradiation (TBI) have been reported for alternative donor hemopoietic stem cell transplants (HSCT). Between 7 September 1994 and 7 June 1999 48 patients with advanced hematologic malignancies were conditioned with thiotepa (THIO) 15 mg/kg, cyclophosphamide (CY) 150 mg/kg and antithymocyte globulin (ATG). Donors were HLA mismatched family members (1-2 antigens) (FAM) (n = 24, median age 31 years) or HLA matched unrelated donors (UD) (n = 24, median age 34 years). GVHD prophylaxis was cyclosporine and methotrexate. Stem cell source was peripheral blood (n = 8) or bone marrow (n = 40). Hematologic recovery was seen in 42/46 (91%) evaluable patients and complete chimerism in 31/37 patients (85%). Acute GVHD grades III-IV were seen in 10/46 patients surviving 10 days (21%) and extensive chronic GVHD in 2/36 patients surviving 100 days (5%). Twenty-six patients died (54%), eight of recurrent disease (17%) and 18 of transplant-related complications (37%): main causes of TRM were GVHD (15%), infections (15%) and graft failure (4%). Twenty-two patients (46%) survive with a median follow-up of 877 days (287-1840). The actuarial 3-year survival is 49% for FAM and 42% for UD transplants. Results obtained with this regimen in unrelated grafts for advanced CML (n = 15) were not significantly different when compared to 21 concurrent UD grafts for advanced CML prepared with CY-TBI. In conclusion, the combination of THIO-CY-ATG allows engraftment of alternative donor hemopoietic stem cells. Results are similar when using unrelated matched donors or partially mismatched family donors, and not significantly different when compared to patients conditioned with CY-TBI.

Abstract
Unrelated donor bone marrow transplant (UD-BMT) has become an attractive alternative source of hematopoietic cells for patients lacking a matched sibling. The aim of this paper was to report on results of the 696 UD BMTs performed in 31 Italian institutions during the first 10 years of activity of the Italian Bone Marrow Donor Registry (IBMDR). In 1989 the Italian Bone Marrow Transplant Group (GITMO) established the IBMDR to facilitate donor search and marrow procurement for patients lacking an HLA identical sibling. By end of December 1999, 260,000 HLA-A, B typed volunteer donors had been cumulatively registered and 2,620 searches had been activated for Italian patients. At least one HLA-A, B, DRB1 matched donor was found for 54% of the patients and 696 UD BMTs were performed. In 50% of cases the donor was found in the IBMDR and in 50% in 15 other Registries. The average time from search activation to transplant was 6 months for disease other than CML. For CML it was 14 months. Actuarial 12-month transplant-related mortality (TRM) was 68% in patients grafted between 1979 and 1992 and 44% for patients grafted after 1993. Twenty-eight per cent of patients developed grade III or IV acute GvHD and 24% developed extensive chronic GvHD. The rate of disease free survival at three years was 57% for patients with 1st chronic phase CML, 37% for patients with 1st or 2nd CR ALL, 31% for AML or MDS patients < or = 18 years of age and 54% for patients with inborn errors. We conclude that the IBMDR has benefited a substantial number of patients lacking a matched sibling and has facilitated the recruitment of UDs into the international donor pool. The long time required for the search is the major obstacle to the success of this programme. This suggests that early transplant and a decrease in TRM could further improve these encouraging results.

Abstract
The number of long-term survivors after allogeneic bone marrow transplantation (BMT) has been increasing over the past years, and quality of life (QOL) has become an important end-point. We studied 244 patients undergoing an allogeneic BMT to identify factors and events influencing psychosocial outcome. Patients enrolled received the Psychosocial Adjustment to Illness Scale (PAIS) questionnaire assessing psychological and social adjustment to chronic illness or its sequelae. Eighty-two per cent of patients had a haematological disease. The median age was 28 years at BMT, and the median follow-up was 61 months. The median overall PAIS score for all patients was 56 (range 22-76): 25% (n = 61) of patients were considered to have a good QOL (</= 25 percentile score); 44% (n = 108) of patients had an intermediate QOL (26-75 percentile score) and 31% (n = 75) had a poor QOL (> 75 percentile score). Factors associated with a poor QOL in multivariate analysis were: patients' age at BMT (> 25 years, P < 0.01); presence of long-term sequelae (P < 0.01); chronic graft-versus-host disease (GVHD) (P < 0.05); and a short interval from BMT (< 5 years; P < 0.05). The QOL improved with time: 12% of patients reported a good QOL within 5 years compared with 38% after this time point and, conversely, 38% reported a poor QOL within 5 years compared with 24% after this time point (P < 0. 0001). Older patients had significantly poorer QOL compared with younger patients (< or = 25 years; P = 0.01). Females had significantly poorer scores when compared with males in the sexual (P < 0.0001) and psychological domains (P = 0.001). The data suggest that (i) one-third of patients undergoing allogeneic BMT report a poor QOL; (ii) factors associated with poor QOL are older age, presence of long-term sequelae, chronic GVHD and short follow-up; (iii) QOL is superior in long-term survivors; and (iv) BMT affects different aspects of life in males and females. A longitudinal study is ongoing to prove the effect of time on quality of life.

Abstract
This is a dose-finding study using foscarnet for CMV prophylaxis after allogeneic bone marrow transplantation (BMT) in 20 high risk patients (unrelated donors, or T cell depleted, and/or advanced disease). Foscarnet was started on day +1 after BMT and continued until day +100. We explored four different dose levels, patients being entered at the lowest dose level until one patient experiences CMV-reactivation, identified as two consecutive positive CMV antigenemias (CMVAg-emia). The four dose levels expressed as mg/kg/day between days 1 and 30 (induction) and between days 31 and 100 (maintenance) were respectively: dose level I = 60/30 (n = 5); dose level II = 120/60 (n = 4); dose level III = 120/90 (n = 5) and dose level IV = 120/120 (n = 6). All patients showed engraftment: PMN > or =0.5 x 109/l at a median interval of 16, 21, 17, 15 days after BMT, and Plt > or =30x10(9)/l on days 19, 16, 17, 17 respectively. CMVAg-emia was seen in 10 patients at a median interval of 53 days post-BMT (range 33-89) with a median of 10 CMV antigen+ cells (range 1-16). There was a dose effect of foscarnet on CMVAg-emia: respectively 4/5 patients (80%), 2/4 (50%), 3/5 (60%) and 1/6 (18%) at dose levels I, II, III, IV (P = 0.1). CMV disease was seen in 3/9 (33%) at dose levels I, II and 0/11 at dose levels III, IV (P = 0. 07). The median number of CMV antigen-positive cells at diagnosis of CMV infection was different: 13 in dose levels I-II and two in dose levels III-IV (P = 0.01). Increased creatininine was seen in 15 patients with a mean of 1.8 mg% (range 1.5-5.7) and was the cause of discontinuation in nine patients (45%). Renal toxicity was reversible in all nine patients. Overall actuarial TRM at 2 years was 31%: 47% for patients at dose levels I-II and 19% for patients at dose levels III-IV. In conclusion, foscarnet exhibits a dose-dependent prophylactic effect on CMVAg-emia, CMV disease and transplant-related mortality with acceptable and reversible renal toxicity.

Abstract
UNLABELLED Transplant-related mortality (TRM) remains a major problem in older patients undergoing allogeneic haemopoietic stem cell transplants (HSCTs). We have therefore explored a less intensive conditioning in 33 patients with a median age of 52 years (range 43-60) transplanted from human leucocyte antigen (HLA)-identical siblings. The underlying disease was chronic myeloid leukaemia (n = 15), acute myeloid leukaemia (n = 6), myelodysplasia (n = 7) or a chronic lymphoproliferative disorder (n = 5); 15 patients (45%) had advanced disease. The regimen consisted of thiotepa (THIO; 10 mg/kg) on day -5 and cyclophosphamide (CY; 50 mg/kg) on days -3 and -2 (total dose 100 mg/kg). The source was bone marrow (BM) (n = 17) or granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood (PB) (n = 16), which were infused without manipulation. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporin A (CyA) and a short course of methotrexate. Mean time to achieve a neutrophil count of 0.5 x 109/l was 17 d (range 11-23) and full donor chimaerism was detected in 79% of patients by day 100. Acute GVHD grade III or IV occurred in 3% of patients. Chronic GVHD was seen in 45% of patients, with a significant difference for PB (69%) compared with BM transplants (23%) (P = 0.009). For BM grafts, the actuarial 2-year TRM was 6%, the relapse 56% and survival 87%; for PB grafts, these figures were, respectively, 27%, 33% and 68%. Twenty-five patients are alive at a median follow-up of 762 d (range 216-1615) and 20 patients (60%) remain free of disease. Thirteen patients (39%) received donor lymphocyte infusion (DLI) either for persisting or relapsing disease and six patients had complete remission. IN CONCLUSION (i) patients up to the age of 60 years can be allografted with reduced intensity conditioning; (ii) the procedure was associated with a low transplant-related mortality, particularly for bone marrow grafts, because of a lower risk of chronic GVHD; and (iii) DLI were required after transplant in half the patients for persisting disease or relapse.

Abstract
One hundred and fifty acute myeloid leukaemia (AML) patients in first remission received an allogeneic bone marrow transplant (BMT), after conditioning with cyclophosphamide 120 mg/kg and total body irradiation (TBI) 3.3 Gy x 3 (total nominal dose 9.9). The received dose, as recorded by thermoluminescent dosimeters, ranged between 7. 83 and 12.25 Gy. Patients who received TBI < 9.9 Gy (n = 34) had a significantly higher relapse rate when compared with patients receiving >/= 9.9 Gy (n = 116) (43% vs. 19%; P = 0.002). Graft versus host disease (GvHD) prophylaxis consisted of cyclosporin A (CyA) with or without methotrexate (MTX). The dose of CyA was either 1 or 5 mg/kg/day i.v. from day -1 to + 20, then 10 mg/kg/day orally until day + 365. Patients receiving 5 mg/kg CyA (n = 40) had a higher risk of relapse (49% vs. 15%; P = 0.0001). Thus, low-dose TBI (< 9.9 Gy) and high-dose CyA (5 mg/kg) were significant predictors of leukaemia relapse. Patients were then divided into three groups: those who had both negative predictors (< 9.9 Gy TBI and 5 mg/kg CyA; n = 26); those who had only one (either < 9.9 Gy TBI or 5 mg/kg CyA; n = 22); and those who had neither (>/= 9.9 Gy TBI and 1 mg/kg CyA; n = 102). The three groups were comparable for FAB subtype, interval diagnosis transplant and age. The 5-year actuarial relapse rate for these three groups of patients was 49%, 41% and 15%, with no difference between the first two and a significant difference when compared with the latter (P < 0.01). These data indicate that acute myeloid leukaemia can be cured with allogeneic bone marrow transplantation given an intensive conditioning regimen and low-dose immunosuppression post-graft. Either alone is insufficient to produce long-term disease-free survival. These results may be relevant for programmes of reduced intensity conditioning designed for patients with acute leukaemia.

Abstract
BACKGROUND AND OBJECTIVE Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disease of the hemopoietic stem cell (HSC) characterized by intravascular hemolysis and increased risk of venous thrombosis. There are different therapeutic approaches for PNH which do not cure the disease, but can decrease its complications. Allogeneic bone marrow transplantation (BMT) may cure PNH. We reports here our experience of seven PNH patients who underwent allogeneic BMT. DESIGN AND METHODS Between January 1991 and January 1999 seven patients with PNH, aged 23 to 37, were transplanted with unmanipulated bone marrow from HLA identical siblings. Median time from diagnosis to BMT was 2.5 years (range: 1-16). All patients were transfusion-dependent and had received various treatments before BMT: steroids, vitamins, cyclosporin A (CyA), growth factors. One patient had also been treated with anti-thymocyte globulin. One patient was HbsAg positive and one anti-HCV positive. At the time of BMT the median value of hemoglobin (Hb) was 9 g/dL (range 6.5-11), white blood cells 5&10(9)/L (range: 2.9-7.7), platelets 97&10(9)/L (range: 31-355), LDH: 2726 U/L. The conditioning regimen was cyclophosphamide (160 mg/kg) and busulfan (10-14 mg/kg), followed by unmanipulated bone marrow (median of 5&10(8) cells/kg) and CyA (+MTX in two patients) for prophylaxis of graft-versus-host disease (GvHD). RESULTS All seven patients are alive, full chimeras, with complete hematologic recovery and no evidence of PNH, at a median follow up of 51 months post-BMT (6-103). Time to achieve a granulocyte count of 0.5&10(9)/L, platelets 30&10(9)/L and Hb 10 g/dL was respectively 16, 19 and 22 days. Acute GvHD was limited or mild in six patients, and severe in one. Chronic GvHD was extensive in two patients. INTERPRETATION AND CONCLUSIONS This study confirms that HLA identical sibling BMT is an effective therapeutic option for PNH, also in the hemolytic phase of the disease: it also suggests that HBV and HCV infections are not an absolute contraindication.

Abstract
Transplant-related mortality (TRM) following allo- geneic bone marrow transplantation (BMT) remains a major concern and early identification of patients at risk may be clinically relevant. In this study we describe a predictive score based on bilirubin and blood urea nitrogen (BUN) levels on day +7 after BMT. The patient population consisted of 309 consecutive patients who underwent BMT from sibling (n = 263) or unrelated donors (n = 46) for hematologic disorders between December 1990 and December 1996. Of 27 laboratory tests taken on day +7 after BMT, serum bilirubin (P = 0.02) and BUN (P = 0.007) were found to be independent predictors of TRM in multivariate analysis. The median levels of bilirubin (0.9 mg/dl) and of BUN (21 mg/dl) were then used as a cut-off and a score of 1 was given for values equal/greater than the median. There were 216 patients with scores 0-1 (low risk) on day +7 (bilirubin <0.9 and/or BUN <21) and 93 patients with score 2 (high risk) (bilirubin >/=0.9 and BUN >/=21): the latter had more grade III-IV acute graft-versus-host disease (P = 0.03), slower neutrophil (P = 0.02) and slower platelet engraftment (P = 0.002). The actuarial 5 year TRM is 22% for low risk vs44% for high risk patients (P = 0.0003). For HLA-identical siblings TRM is 20% vs35% (P = 0.01), for unrelated donors it is 20% vs 65% (P = 0.01). Day +7 score was highly predictive of TRM on multivariate analysis (hazard ratio 1.9, P < 0.01), after adjustment for year of transplant (P < 0.00001), unrelated vs sibling donors (P = 0.001), patient age (P = 0.01) and diagnosis (P = 0.01). These results were validated on an independent group of 82 allogeneic BMT recipients in a pediatric Unit who showed an actuarial TRM of 16% for low risk vs 46% for high risk patients (P = 0.002). This study suggests that it may be possible to identify patients with different risks of TRM on day +7 after BMT: high risk patients could be eligible for programs designed to intensify prophylaxis of post-transplant complications.

Abstract
BACKGROUND AND OBJECTIVE The best post-remission therapy for patients with acute lymphoblastic leukemia (ALL) is controversial, and hemopoietic stem cell transplantation (HSCT) is one therapeutic option. The goal of this study is to describe long term results of HSCT in high risk ALL patients. DESIGN AND METHODS Between 1978 and 1996, 170 patient with ALL and a median age of 22 years (1-49), underwent an allogeneic HSCT from HLA-identical siblings (n = 149), family mismatched donors (n = 18) or unrelated HLA matched donors (n = 3); 92% of patients had at least one adverse prognostic factor for high risk ALL at diagnosis; one third (33%) were in first remission (CR1) and the majority (85%) received an unmanipulated HSCT with cyclosporin-methotrexate prophylaxis of graft-versus-host disease (GvHD). RESULTS After a median follow-up of over 6 years, 59 patients are alive and 111 patients have died of leukemia (46%) or transplant related complications (54%). The actuarial 10 year survival is 53%, 38% and 20%, for patients in CR1, CR2 or advanced phase, respectively. The actuarial survival of patients with (n = 24) of without (n = 46) cytogenetic abnormalities, grafted in CR1/CR2 was respectively 45% and 48% (p = 0.5). The year of transplant had a significant impact in multivariate analysis on transplant related mortality (TRM) (p = 0.0009) but not on relapse (p = 0.3). Chronic GvHD was the most important favorable prognostic factor for survival (p = 0.0014) and relapse (p = 0.0019). INTERPRETATION AND CONCLUSIONS This study confirms that long term survival can be achieved with HSCT in ALL patients, even those with cytogenetic abnormalities. Transplant mortality has been significantly reduced in recent years, whereas leukemia rate relapse has remained unchanged: the latter is influenced by the occurrence of chronic GvHD. Immune intervention post-HSCT may be considered to address this problem.

Abstract
A 44-year-old man with splenectomised refractory autoimmune thrombocytopenic purpura (AITP) of 10 years' duration underwent an autologous, T cell-depleted marrow transplant following conditioning with thiotepa and CY. There was no response to the transplant procedure. This is the fourth case in the literature to show failure following autologous stem cell transplantation, although complete, steroid-independent remissions were obtained in the first two patients for over 1 year.

Abstract
Between January 1989 and July 1995 the search for an unrelated donor (UD) was started for 379 consecutive Italian patients with Philadelphia positive (Ph+) chronic myelogenous leukaemia (CML). 89 (23%) were transplanted. The overall probability of transplant before and after December 1991 was 16% and 49%, respectively (P=0.0001), and average interval between search activation and graft was 23 months and 13 months, respectively (P=0.0001). Disease-free survival (DFS) following 60 consecutive transplants performed before February 1996 was 41.5% at 48 months and was 64% for patients grafted after January 1993. In univariate analysis, five variables had a favourable effect on DFS: year of bone marrow transplantation (BMT) after 1993 (P=0.0002), HLA-DRB1 donor/recipient (D/R) match (P=0.0006), total body irradiation (TBI) containing regimen (P=0.0006), graft-versus-host disease (GvHD) prophylaxis including 'early' cyclosporin before the transplant, and a marrow cell dose > 3 x 10(8)/kg of recipient body weight (P=0.04). Multivariate analysis confirmed that HLA identity (P=0.006), TBI-containing regimen (P=0.0001) and 'early cyclosporin' (P=0.04) were associated with higher DFS. Transplant-related mortality (TRM) was 67% in patients grafted before January 1993 and 30% in patients grafted subsequently (P=0.002). Multivariate analysis confirmed DRB1 identity (P=0.03) and TBI-containing regimen (P=0.0005) to be independent factors predictive of low TRM. This suggests that the outcome of patients transplanted from an HLA DRB1 matched donor, after a TBI-containing preparative regimen, is similar to results recently reported in patients transplanted from geno-identical siblings. These results indicate that the search should be initiated at diagnosis for patients < 45 years of age and UD BMT should be considered early in the disease course for those with an available DRB1-matched unrelated donor.

Abstract
This trial was designed to compare foscarnet with ganciclovir as pre-emptive therapy for CMV infection in patients undergoing allogeneic hemopoietic stem cell transplant (HSCT). Thirty-nine patients were randomized to receive foscarnet 90 mg/kg every 12 h (n = 20) or ganciclovir 5 mg/kg every 12 h (n = 19) for 15 days at the time of development of CMVAg-emia. Primary-end points of the study were (1) outcome of CMVAg-emia; (2) progression to CMV disease; and (3) side-effects of treatment. The secondary end-point was transplant-related mortality (TRM). The two groups were comparable for diagnosis, status of disease, donor type, acute graft-versus-host (aGVHD) prophylaxis, interval between HSCT and CMVAg-emia and number of CMVAg positive cells; the donor and recipient age were borderline older in the foscarnet group. Increments of serum creatinine in the foscarnet group, and cytopenia in the ganciclovir group were controlled by reducing the administered dose: in the first 15 days of therapy 9/20 foscarnet and 10/19 ganciclovir patients had a dose reduction greater than 20% (P = 0.43). Clearance of CMVAg-emia was faster in the foscarnet group although with borderline statistical significance. Failures of treatment occurred in 3/20 patients in foscarnet group vs 8/19 patients in ganciclovir group (P= 0.06): causes of failure were the need for combination therapy to control antigenemia (1/20 vs 5/19), and reactivation during treatment for 2 vs 3 patients, respectively. CMV disease was diagnosed in 1 vs 2 patients (P = 0.5) who subsequently died. The actuarial 1-year TRM was 25 vs 12%, respectively (P = 0.3). This study suggests that foscarnet and ganciclovir are both effective for pre-emptive therapy of CMVAg-emia, although the number of failures would seem to be slightly higher in the ganciclovir patients. Side-effects are seen in both groups and can be managed with appropriate dose reduction.

Abstract
This is a retrospective study of 97 patients who received either allogeneic bone marrow transplant (BMT) (n=52) or peripheral blood cell transplant (PBCT) (n=45) at our institution from human leukocyte antigen (HLA)-identical sibling donors between January 1994 and January 1997. The two groups were comparable with respect to diagnosis, age, sex, interval from diagnosis, and disease phase. They were prepared with cyclophosphamide (CY) and fractionated total-body irradiation (TBI) (n=51) or CY and thiotepa (n=46). Graft-vs.-host disease (GVHD) prophylaxis consisted of cyclosporin A and methotrexate. Patients who received PBCT exhibited faster neutrophil engraftment (day 14 vs. day 16, p = 0.002) than those in the BMT group, as well as higher platelet counts on day 20 (32x10(9)/kg vs. 21x10(9)/kg, p = 0.001), but graft function as assessed by platelet counts on days 50, 100, and thereafter was comparable. The number of days spent in the hospital, days on intravenous antibiotics, and days of fever were lower in the PBCT group, but not significantly. Acute GVHD, chronic GVHD, and cytomegalovirus infections were comparable between the two groups. The overall actuarial 3-year transplant-related mortality (TRM) rate for BMT vs. PBCT patients was 20 vs. 33% (p = 0.1), the survival rate was 53 vs. 48% (p = 0.3), and the relapse rate was 42 vs. 43% (p = 0.8). For patients in first complete remission, these figures were TRM 12 vs. 22% (p = 0.2), survival rate 75 vs. 70% (p = 0.4) and relapse rate 31 vs. 9% (p = 0.4), respectively, for the BMT and PBCT groups. These data suggest that the short-term outcome of allogeneic PBCT is not significantly different from that of allogeneic BMT in patients with hematologic malignancies. Long-term results are not available at present.

Abstract
Sixty patients undergoing allogeneic bone marrow transplant for acute myeloid leukemia (AML) in first remission (CR1; n = 49) or more advanced phase (n = 11) were entered in a prospective trial of graft-versus-host disease (GvHD) prophylaxis: low-dose cyclosporin A (IdCSA; 1 mg/kg/d from day -1 to +20 day; n = 28) or IdCSA plus low-dose methotrexate (IdMTX; 10 mg/m2 for day +1, 8 mg/m2 for days +3, +6, and +11; n = 32). Primary end points were acute GvHD (aGvHD) and transplant-related mortality (TRM); secondary end points were relapse and survival. The conditioning regimen consisted of cyclophosphamide (120 mg/kg) and fractionated total body irradiation (3.3 Gy/d for 3 consecutive days). The actuarial risk of developing aGvHD grade II-III was 61% for IdCSA alone and 34% for IdCSA + IdMTX (P = .02). The actuarial risk of TRM at 1 year was 11% versus 13%, respectively, and older patients (>/= 29 years) had higher TRM than younger patients (22% v 5%, P = .01). The age effect was significant in the IdCSA group (P = .04) but not in the IdCSA + IdMTX group (P = .1). The median follow-up is 4.4 years, with an overall actuarial survival of 78% for CR1 patients and 36% for patients with advanced disease. For patients in CR1 the outcome of the two regimens was as follows: survival 77% versus 80% (P = .6), relapse 20% versus 9% (P = .1), and TRM 13% versus 17% (P = .6). This study suggests that TRM can be reduced in AML patients undergoing allogeneic marrow transplants with a mild conditioning regimen and low-dose immunosuppression, and this translates in a 78% 5-year survival for CR1 patients. Beyond CR1 the major obstacle remains leukemia relapse, which is not prevented by low-dose in vivo immunosuppression.

Abstract
BACKGROUND AND OBJECTIVE The role of high dose intravenous IgG (HDIgG) and of hyperimmune CMV IgG (CMV-IgG) in patients undergoing allogeneic hemopoietic stem cell transplantation (HSCT) is still unclear. The aim of this study was to compare prophylactic CMV-IgG with HDIgGin a randomized prospective trial in allogeneic HSCT recipients: primary end point of the study was the occurrence of post-transplant CMV antigenemia (CMVAg-emia). Secondary end-points were severity of acute and chronic graft-versus-host disease (GvHD), infections and transplant related mortality (TRM). DESIGN AND METHODS Patients were randomized to receive 100 mg/kg/week of CMV-IgG (group A; n = 64) or 400 mg/kg/week of HDIgG (group B; n = 64) from day -7 to day +100. The two groups were comparable for age, diagnosis, disease status, and acute graft-versus host (aGvHD) prophylaxis. RESULTS The actuarial risk at 1 year of CMV antigenemia was lower for CMV-IgG (61% vs. 71%) but not significantly (p = 0.37); CMVAg-emia occurred at the same interval from HSCT (47 vs. 48 days, p = 0.9), with a comparable number of CMVAg positive cells (3 vs. 3 p = 0.9). Eight patients died of interstitial pneumonia (IP) (4 in each group), two in group A of CMV-IP. Acute GvHD was scored as O-I, II and III-IV in 39 vs. 35, 23 vs. 22 and 2 vs. 7 patients respectively for the two groups (p = not significant). The actuarial risk of developing acute GvHD grade II-IV was lower for CMV-IgG (39% vs. 45%) but not significantly (p = 0.43). Chronic GvHD scored as absent in 7 vs. 10 patients, limited in 39 vs. 37 and extensive in 19 vs. 17 patients respectively (p = not significant). Numbered days with intravenous antibiotics, days in hospital, days of fever, number of local and disseminated infections, number of patients with fever of unknown origin were not significantly different. Actuarial 1 year TRM is 18% vs. 19%, respectively (p = 0.9). INTERPRETATION AND CONCLUSIONS This study confirms that CMV antigenemia is comparable in recipients of hyperimmune CMV-IgG and of polyvalent HDIgG, although the former had a 32% lower cost. It also shows that the potential immunomodulating effect on acute GvHD and transplant mortality is similar with 100 or 400 mg of IgG/kg/week: this is relevant, in view of the high cost of prophylactic HDIgG.

Abstract
This is a report on 60 consecutive patients with chronic myeloid leukemia (CML) who received an allogeneic bone marrow transplant (BMT) in this Unit. Donors were HLA-identical siblings (SIB) (n = 36) or unrelated donors (MUD) (n = 24) matched by serology for HLA A and B and by molecular biology for HLA DR. All patients were prepared with cyclophosphamide 120 mg/kg and fractionated total body irradiation 10-12 Gy. GVHD prophylaxis consisted of cyclosporin A (CsA) starting on day -7 and short-course methotrexate. Bone marrow was unmanipulated in all cases. Cytomegalovirus prophylaxis consisted of acyclovir for SIBs and foscarnet for MUDs. When compared to SIB transplants, MUD patients were younger (29 vs 36 years; P = 0.002), had younger donors (31 vs 39; P = 0.001), had a longer interval between diagnosis and BMT (1459 vs 263 days; P < 0.001) and received a smaller number of nucleated cells at transplant (3.3 vs 4.4 x 10(8)/kg; P = 0.003). More MUDs had advanced disease (50 vs 17%, P = 0.005). The median day to 0.5 x 10(9)/l neutrophils was similar in both groups (18 days for SIBs vs 17 days for MUDs; P = 0.06); the median platelet count on days +30, +50, +100 was significantly (P < 0.01) higher in SIB than in MUD patients (122 vs 38, 113 vs 50 and 97 vs 45 x 10(9)/l, respectively). Acute GVHD was scored as absent-mild, moderate, or severe, in 36, 58 and 6% of SIBs vs 25, 42 and 33% in MUD patients (P = 0.01). Chronic GVHD was comparable (P = 0.1). The actuarial risk of CMV antigenemia at 1 year was 60% in both groups. There were six deaths in SIB patients (two leukemia, two infections, one GVHD, one pneumonitis) and four deaths in MUD patients (three acute GVHD and one infection). Fifty patients survive with a median follow-up of 656 days for SIBs and 485 for MUDs. The actuarial 3-year transplant-related mortality is 12% in SIBs and 17% in MUDs (P = 0.5); the actuarial relapse is 18% in SIBs vs 6% in MUDs (P = 0.4) and 3-year survival 78% in SIBs vs 82% in MUDs (P = 0.7). This study suggests that survival of CML patients after marrow transplantation from unrelated or sibling donors is currently similar, provided the former are well matched. The increased incidence of GVHD in MUD patients is possibly compensated by a lower risk of relapse.

Abstract
This trial was designed to test the use of CD34+ selected haemopoietic stem cells (HSC) in HLA-mismatched donor-recipient pairs, following intensive conditioning with thiotepa, antilymphocyte globulin (ALG), cyclophosphamide and single-dose total-body irradiation (sTBI). 10 patients aged 16-50 with advanced malignancies and a two- or three-antigen mismatched family donor entered this study. Donor marrow and G-CSF primed peripheral blood cells were processed separately on CD34 columns (Ceprate). The median number of infused CD34+ cells were 5.66 x 10(6)/ kg, with 0.55 x 10(6)/kg CD3+ cells. Nine patients received cyclosporin for graft-versus-host disease (GvHD) prophylaxis. Median neutrophil counts on day 21 were 2 x 10(9)/l with a median platelet count of 60 x 10(9)/l, but CD4 counts remained extremely depressed throughout the study. Acute GvHD was scored as grade 0-I in two patients, as grade II in seven, and grade III in one. Eight patients died at a median interval of 72 d from HSCT (range 20-144) due to cytomegalovirus (CMV) associated interstitial pneumonitis (IP) (n = 5), renal failure (n = 1). GvHD (n = 1) and Aspergillus meningitis (n = 1). Two patients are alive 365-495 d post transplant, one in remission and one in relapse. This study suggests that large numbers of positively selected mismatched HSC can rapidly engraft after intensive conditioning regimen: however, profound post-transplant immunodeficiency leads to a high risk of lethal infectious complications.

Abstract
Donor lymphocyte infusions (DLI) were given between June 1990 and March 1996 to 18 patients with chronic myeloid leukemia (CML) for the treatment of cytogenetic (n = 6) or hematologic relapse (n = 12) following an allogeneic bone marrow transplant (BMT). Patients were divided in two groups: patients in group A (n = 8) received a large dose of donor lymphocytes (> or = 1 x 10(8)/kg), whereas patients in group B (n = 10) received escalating numbers of cells (2 x 10(5) up to 2 x 10(8)/kg). The median number of DLI in group A was 2 (range 1-3); the median number of infusions in group B was 7 (range 3-9). Acute GVHD occurred in 12 patients (grades I-III) and was a major cause of death in two. The risk of developing GVHD correlated with the number of cells infused: 37%, 14%, 5% and 0% for DLI with cells > or = 1 x 10(8), 2 x 10(7)/kg, 2 x 10(6)/kg, and 2 x 10(5)/kg, respectively (P = 0.01). Median transaminase levels were found to be significantly increased in patients with, as compared to patients without, acute GVHD (GPT 412 vs 28 IU/l; P = 0.03). Severe aplasia occurred in four and was a contributing cause of death in two patients. Overall, four patients died as a consequence of DLI and all received > 1 x 10(8)/kg cells: the actuarial risk was 38% in group A and 14% in group B (P = 0.1). There were 10 complete and three partial cytogenetic responses: the actuarial probability at 5 years of being Ph negative was 69%: it was 46% for group A and 85% for group B (P = 0.1). The longest patient is now 6 years post-DLI, Ph negative, BCR-ABL negative. The actuarial 3 year survival is 38% in group A and 86% in group B (P = 0.06). The study confirms that DLI post-BMT is not innocuous and that there is a definite long-lasting antileukemic effect in patients with CML. It also suggests that: (1) the risk of developing GVHD correlates with the number of infused cells; (2) that significant elevations of serum GPT levels are associated with GVHD; and (3) that the use of escalating doses of cells may allow the identification of side-effects and discontinuation of infusions before life-threatening GVHD has developed.

Abstract
Thirty two allogeneic bone marrow transplant (BMT) recipients, aged 16-55 (median 35), with CMV antigenemia (= > 5 positive cells) developing at a median interval from BMT of 49 days, were given combined treatment with foscarnet and ganciclovir for 15 days. Maintenance was given with foscarnet and ganciclovir on alternate days for an additional 2 weeks. 31/32 patients were on cyclosporin 30 on systemic antibiotics and 9 were on intravenous amphotericin Median laboratory values on day 1 and 15 of treatment were respectively creatinine 1.0-1.1 mg%; WBC 5.7-4.1 x 10(9)/l; platelets 78 72 x 10(9)/l. All patients cleared CMV-antigenemia by day +15, though 5 reactivated on and 14 off maintenance: the dose of foscarnet (but not ganciclovir) received in the first 15 days was significantly lower in patients reactivating within 30 days (p = 0.0002). Six patients died, one with i.p., one with multiorgan failure, and four with infections. Eighteen patients survive 119-1051 days post-transplant. The actuarial TRM at 1 year is 23%. This study shows that combined foscarnet-ganciclovir is one therapeutic option for allogeneic BMT recipients developing CMVAg-emia with a high number of CMVAg+ cells: treatment can be given together with cyclosporin and antibiotics with appropriate dose reductions; it produces prompt clearing of CMV infection, and may reduce transplant related mortality when compared to single agent therapy.

Abstract
BACKGROUND Cytogenetic abnormalities have been described in a few patients with otherwise typical severe aplastic anemia (SAA), and the possible clonal nature of this disease is a controversial issue. MATERIALS AND METHODS Sixty-nine patients with acquired severe aplastic anemia underwent cytogenetic examination on bone marrow cells at the time of diagnosis (n = 34) and/or at least twice after immunosuppressive therapy (IS) (n = 35). RESULTS We identified 2 major groups. Group A: 51 patients (74%) were normal and remained normal. Group B: 18 patients (26%) had at least one abnormal cytogenetic analysis. This second group could be further subdivided as follows: (B1) chromosomal abnormalities not present at first examination and acquired in the course of the disease (n = 7); (B2) clonal cytogenetic abnormalities present at first examination and persisting (n = 3); (B3) reversible cytogenetic abnormalities (n = 8). The most frequent abnormality was trisomy 8 (n = 8) followed by monosomy 7 (n = 2); 82% of patients are alive in group A and 61% in group B. Three patients developed acute leukemia, all from group B. This represents 4% of all patients or 17% of those with at least one abnormal cytogenetic test. CONCLUSIONS Thus the majority of SAA patients have normal karyotypes in marrow cells at presentation and at follow-up. Patients with abnormal karyotypes exist and can be further subdivided into those with reversible and those with persistent abnormalities. The latter are at risk of developing myelodysplasia or acute leukemia.

Abstract
In a previous study, we showed that patients undergoing allogeneic hemopoietic stem cell transplantation (HSCT) who had cytomegalovirus (CMV) antigenemia with more than 4 CMV antigen-positive cells/200,000 have a high transplant-related mortality (TRM) rate, despite treatment with ganciclovir or foscarnet. In an attempt to reduce TRM, 32 allogeneic HSCT recipients, between the ages of 16 and 55 years (median, 35 years), with CMV antigenemia (> or = 5 positive cells) developing at a median interval from HSCT of 49 days, were given combination treatment with foscarnet and ganciclovir for 15 days. The prescribed dose was 180 mg/kg/day of foscarnet and 10 mg/kg/day of ganciclovir: the median administered dose in the first 15 days, after adjusting for creatinine levels and peripheral blood counts, was 64% for foscarnet and 53% for ganciclovir. Maintenance was given with foscarnet and ganciclovir on alternate days for an additional 2 weeks. Thirty-one of 32 patients were on cyclosporine, 30 were on systemic antibiotics, and 9 were on intravenous amphotericin. Median laboratory values on days 1 and 15 of treatment were 1.0 and 1.1 mg/100 ml creatinine, 5.7 x 10(9)/L, and 4.1 x 10(9)/L white blood cells, and 78 x lO(9)/L and 72 x 10(9)/L platelets. All patients cleared CMV antigenemia by day +15, although CMV antigenemia recurred in 5 patients on maintenance therapy and in 14 patients off maintenance therapy: the dose of foscarnet (but not ganciclovir) received in the first 15 days was significantly lower in patients in whom antigenemia recurred within 30 days (P=0.0002). Six patients died, one with interstitial pneumonia, one with multiorgan failure, and four with infections. Twenty-six patients survived 119-1051 days after transplant. The actuarial TRM rate at 1 year is 23%. Eighteen patients who had received unmanipulated bone marrow transplants from HLA-identical siblings were compared with 15 matched controls who had been treated with a single drug (either foscarnet or ganciclovir) for CMV antigenemia (> or = 5 cells): the actuarial 1 year TRM rate was 13% for patients receiving combined treatment, compared with 47% for controls receiving a single drug (P=0.02). This study shows that combined foscarnet-ganciclovir is one therapeutic option for allogeneic HSCT recipients who develop CMV antigenemia with a high number of CMV antigen-positive cells. Treatment can be given together with cyclosporine and antibiotics with appropriate dose reductions. It produces prompt clearing of CMV infection, and may reduce TRM rates in comparison to single-agent therapy.

Abstract
Thirty-one patients (median age, 44 years) with advanced hematologic malignancies were given thiotepa 15 mg/kg, and cyclophosphamide 120 (n = 14) or 150 (n = 17) mg/kg followed by unfractionated peripheral blood stem cell transplants (PBSCT) from genotypically identical siblings (n = 28) or one antigen mismatched family donor (n = 3). Donors were mobilized with granulocyte colony-stimulating factor 5 to 10 microgram/kg/d for 6 days and underwent two to three leukapheresis on days +5, +6, +7. The median cell yield per donor expressed/kg of recipients body weight was as follows: nucleated cells 13 x 10(8)/kg; CD34+ cells 6 x 10(6)/kg; colony-forming unit-granulocyte macrophage 38 x 10(4)/kg, and CD3+ cells 449 x 10(6)/kg. The diagnoses were chronic myeloid leukemia (n = 4), acute myeloid (n = 9) or lymphoid leukemia (n = 2), acute myelofibrosis (n = 2), multiple myeloma (n = 1), lymphoma (n = 6), chronic lymphocytic leukemia (n = 1) myelodysplasia (n = 6). Twenty-eight patients had advanced disease, 29 patients were first grafts, and 2 were second transplants 3 and 9 years after the first. Neutrophil counts of 0.5 x 10(9)/L and platelet counts of 30 x 10(9)/L platelets were both achieved on day +14 (median). Engraftment could be proven by sex markers or DNA polymorphism in 29 of 31 patients: one had early leukemia relapse and one patient was unevaluable because of early death. Acute graft-versus-host disease (GVHD) was scored as minimal or absent (grade 0 to 1) in 14 patients, moderate (grade II) in 13, and severe (grade III to IV) in four. Causes of death were leukemia (n = 4), acute GVHD (n = 4, with associated cytomegalovirus infections in three), sepsis (n = 1), liver failure (n = 1), multiorgan failure (n = 1), and hemorrhage (n = 1). The actuarial transplant mortality is 29%, the actuarial relapse rate 22%. Nineteen patients survive with a median follow up of 288 days (100-690). The actuarial 2-year survival is 57%. Three patients received PBSCT from family donors mismatched for one class II antigen: all engrafted, one developed grade I aGVHD; one died of leukemia on day +155; two are alive disease free 267 to 290 days postgraft. This study suggests that thiotepa cyclophosphamide followed by unfractionated PBSC allograft may be an alternative form of transplant for adults with advanced leukemia, also in the setting of one antigen mismatched donor. The engraftment is rapid with acceptable GVHD and relatively low transplant-related mortality.

Abstract
From 1 September 1988 to 30 September 1993, a search for an unrelated donor (URD) was started for 633 Italian patients. Eighty-five of them (13%) were transplanted. Despite the introduction of more strict criteria for the selection of compatible donors, the percentage of patients who reached transplant increased significantly after December 1992. For patients who started a search before and after January 1993, respectively the probability of transplant by 8 and 16 months from search activation was 4 and 10%, compared to 22 and 37% (P = 0.0001). The average intervals between search activation and graft were 15 and 8 months respectively, for the first and second group (P = 0.0001). Data of 75 consecutive transplants performed up to March 1994 were analyzed. Actuarial 2-year survival was 15% for patients grafted before 1992 and 40% for those grafted after January 1992. In this latter period, survival of patients with malignant and non-malignant disorders was 32 and 67%, respectively. In univariate analysis, patients younger than 16 years (P = 0.01), patients grafted after 1992 (P = 0.01) and patients receiving the marrow from a 6-antigen matched donor (P = 0.01) showed a higher survival probability. Multivariate analysis did not show any difference, probably due to the low number of patients and to short follow-up. The adoption of stricter and more accurate HLA-matching criteria and the consequent reduction of deaths related to acute GVHD were the main reasons for the improvement of survival observed in patients grafted after 1992.
