In this single-center study, we retrospectively analyzed incidence and risk factors for hepatic veno-occlusive disease (VOD) in 249 consecutive patients who underwent allogeneic hematopoietic stem cell transplantation between January 1990 and June 1995. Twenty-four of the 249 transplanted patients developed VOD. The probabilities of developing VOD were 17% among women and 7% in men (P =.01). In women treated with norethisterone, the incidence was 27% compared with 3% in women without this treatment (P =.007). One-year survival rates were 17% and 73% in patients with (n = 24) or without VOD (n = 225), respectively. The use of heparin prophylaxis (100 IE/kg/24 hours for 1 month) did not alter the incidence or 1-year mortality of VOD. In multivariate analysis, the following risk factors were significant: norethisterone treatment (P <.001), bilirubin >26 micromol/L before bone marrow transplantation (BMT) (P =.002), one HLA-antigen mismatch (P =.003), previous abdominal irradiation (P =.02), and conditioning with busulphan (P =.02). Our conclusion is that norethisterone treatment should not be used in patients undergoing BMT and heparin prophylaxis did not affect the incidence or mortality of VOD.  相似文献

PURPOSE: Advances in bone marrow transplantation (BMT) have consistently improved long-term survival. Therefore, evaluation of late complications such as cataracts is of paramount importance. METHODS AND MATERIALS: We analyzed data of 2149 patients from the EBMT registry. A cohort of 1063 patients were evaluable for survival and ophthalmologic status after transplant for acute leukemia (AL) in first or second complete remission. Conditioning therapy included either single-dose total body irradiation (STBI) or fractionated TBI (FTBI) grouped in different dose rates (low: LDR < or = 0.04 Gy/min; high: HDR > 0.04 Gy/min). RESULTS: The overall 10-year estimated cataract incidence (ECI) was 50%. It was 60% in the STBI group, 43% in the FTBI group < or = 6 fractions, and 7% in the FTBI group > 6 fractions (p < 10(-4)). It was significantly lower (30%) in the LDR than in the HDR groups (59%;p < 10(-4)). Patients receiving heparin for veno-occlusive disease prophylaxis had fewer cataracts than those who did not (10-year ECI: 33% vs. 53%, respectively;p = 0.04). The 10-year ECI was 65% in the allogeneic vs. 46% in the autologous BMT patients (p = 0.0018). Factors independently associated with an increased risk of cataract were an older age (> 23 years), higher dose rate (> 0.04 Gy/min), allogeneic BMT, and steroid administration (> 100 days). The use of FTBI was associated with a decreased risk of cataract. Heparin administration was a protective factor in patients receiving STBI. In terms of cataract surgery, the unfavorable factors for requiring surgery were: age > 23 yr, STBI, dose rate > 0.04 Gy/min, chronic graft-vs.-host disease (cGvHD), and absence of heparin administration. Among the patients who required cataract surgery (111 out of 257), secondary posterior capsular opacification was observed in 15.7%. CONCLUSION: High dose rate and STBI are the main risk factors for cataract development and the need for surgery, and the administration of heparin has a protective role in cataractogenesis.  相似文献

Transplantation of peripheral blood progenitor cells (PBPCs) has largely replaced autologous bone marrow transplantation. The same might occur in the allogeneic setting if the favourable initial experience with allogeneic PBPCT is confirmed. We analysed all primary transplants utilizing unmodified PBPC from HLA-identical sibling donors reported to the European Group for Blood and Marrow Transplantation (EBMT) for 1994. 59 patients with a median age of 39 years received myeloablative therapy for acute myelogenous leukaemia (23 patients, acute lymphoblastic leukaemia (13), chronic myelogenous leukaemia (nine), lymphoma (seven), or other diagnoses (seven) mostly of advanced stages followed by transplantation of allogeneic PBPC. Three patients died soon after grafting, the others showed prompt haemopoietic recovery with median times to recover an absolute neutrophil count (ANC) above 0.5 and 1.0 x 10(9)/I of 15 (range 9-27) and 17d (range 10-28) respectively. Time to platelet recovery above 20 or 50 x 10(9)/I was 16 (range 9-76) and 18d (range 12-100) respectively. 27 patients (46%) developed no or mild acute graft-versus-host disease (GVIID). The incidence of moderate (grade II) disease was 27%; 24% of the patients developed severe acute GVHD (grades III or IV), 55% of patients who were alive 90d after transplantation developed chronic GVHD, the probability to develop extensive chronic GVHD was 32% (95% confidence interval 22-42) with a median follow-up of 14 months. Overall and event-free survival (EFS) at 1 year were 54% (CI 48-60) and 50% (CI 43-57), respectively, the relapse incidence was 23% (CI 17-29). EFS was 67% (CI 55-79) in patients transplanted for acute leukaemias in first complete remission, chronic myelogenous leukaemia in first chronic phase, or severe aplastic anaemia. Transplantation of allogeneic PBPC resulted in prompt and durable engraftment. The incidence and severity of acute and chronic GVHD seemed comparable to that observed after allogeneic BMT. Overall and event-free survival in this cohort of patients, most of whom suffered from advanced leukaemia or lymphoma, is encouraging, suggesting that the high numbers of T lymphocytes and/or natural killer cells contained in a typical PBPC collection product exert a vigorous graft-versus-leukaemia effect. Further evaluation of allogeneic PBPCT is highly desirable.  相似文献

We performed retrospective analysis of hepatic veno-occlusive disease (VOD) in 57 cases with leukemia after allogeneic bone marrow transplantation (BMT). Prostaglandin E1 (PGE1) was used to prevent VOD in 8 cases at a dose of 0.3 micrograms/kg/hr from day -8 to day 30. No VOD was noted in the PGE1 group, while the incidence of VOD was 8/49 (16.3%) in the non PGE1 group. In twelve patients with pretransplant liver dysfunction, VOD was noted in 0/3 in the PGE1 group and 4/9 (44.4%) in the non PGE1 group, respectively. However, prophylactic effects of PGE1 on VOD is not significant in this study, so further studies are needed to determine the efficacy of PGE1. One of 8 patients with PGE1 prophylaxis had edema and erythema on extremities, however, severe toxicity was not experienced.  相似文献

In a multicentre trial involving 20 transplant centres from 10 countries haematopoietic stem cells were obtained either from the bone marrow of 33 sibling donors or from the peripheral blood of 33 such donors after administration of filgrastim (10 microg/kg/day). The haematopoietic stem cells were infused into their HLA-identical recipients suffering from acute leukaemias in remission or chronic myeloid leukaemia in chronic phase. PBPC donors tolerated filgrastim administration and leukapheresis well with the most frequent side-effects being musculoskeletal pain, headache, and mild increases of LDH, AP, Gamma-GT or SGPT. Pain and haematoma at the harvest site and mild anaemia were the most frequent complaints of BM donors. Severe or life-threatening complications were not seen with any type of harvest procedure. Time to platelet recovery greater than 20 x 10(9)/l was 15 days (95% confidence interval (CI) 13-16 days) in the PBPCT group and 19 days (CI 16-25) in the BMT group. Time to neutrophil recovery greater than 0.5 x 10(9)/l was 14 days (CI 12-15 days) in the PBPCT group as compared to 15 days (CI 15-16 days) in the BMT group. The numbers of platelet transfusions administered to PBPCT and BMT patients were 12 (range: 1-28) and 10 (range: 3-39), respectively. Sixteen patients (48%) transplanted with bone marrow and 18 patients (54%) transplanted with PBPC developed acute GVHD of grades II-IV; acute GVHD of grades III or IV developed in six (18%) and seven (21%) patients, respectively. Kaplan-Meier plots for transplant-related mortality until day 100 and leukaemia-free survival at a median of 400 days after BMT or PBPCT showed no significant differences. Administration of filgrastim and leukapheresis in normal donors were feasible and well tolerated. The number of days with restricted activity and of nights spent in hospital was lower in donors of PBPC. Transplantation of PBPC to HLA-identical siblings with early leukaemia resulted in earlier platelet engraftment. The incidence of moderate to severe acute GVHD, transplant-related mortality, and leukaemia-free survival did not show striking differences. Further investigation of allogeneic PBPCT as a substitute for allogeneic BMT is warranted.  相似文献

The purpose of this study was to determine the long-term results of allogeneic bone marrow transplantation for chronic myeloid leukemia. A retrospective analysis was carried out of the outcome of 373 consecutive transplants performed at 38 European institutions between 1980 and 1988 and reported to the registry of the European Group for Blood and Marrow Transplantation. All transplants were carried out for first chronic phase of chronic myelogenous leukemia using unmanipulated marow cells from HLA-identical sibling donors. The probability of survival and leukemia-free survival at 8 years were 54% (95% CI: 49-59) and 47% (95% CI: 41-52) respectively. The probabilities of developing acute GVHD (II-IV) at 100 days and chronic GVHD at 4 years after transplant were 47% (95% CI: 41-53) and 52% (95% CI: 46-58) respectively. The probabilities of transplant-related mortality and leukemic relapse 8 years after BMT were 41% (95% CI: 36-48) and 19% (95% CI: 14-25), respectively. Transplant within 12 months of diagnosis was associated with reduced transplant-related mortality (34 vs 45%, P = 0.013) and resulted in improved leukemia-free survival (52 vs 44%, P = 0.03). The probability of relapse was significantly reduced in patients who developed chronic GVHD (RR = 0.33, P = 0.004). The probability of relapse occurring more than 2 years after transplant was increased more than five-fold in patients transplanted from a male donor (RR = 5.5, P = 0.006). Sixty-seven patients in hematologic remission were studied for residual disease by two-step RT/PCR for BCR-ABL mRNA and 61 (91%) tested negative. We conclude that bone marrow transplantation can induce long-term survival in approximately one-half of CML patients; the majority of survivors have no evidence of residual leukemia cells when studied by molecular techniques. The probability of late relapse is increased with use of a male donor.  相似文献

One hundred and forty children with hematologic malignancies undergoing allogeneic BMT were reviewed in order to clarify the incidence, onset time, and risk factors for veno-occlusive disease (VOD) of the liver. Thirty-eight patients (27.1%) developed VOD diagnosed according to the Seattle clinical criteria. Seventeen patients developed VOD within 20 days of transplantation (early-onset) and in 21 patients developed after day 20 (late-onset) including eight patients with histological confirmation. Late-onset VOD occurred from day 21 to day 508 (median day 39). Moderate or severe VOD developed in 11 early-onset and 13 late-onset patients. Death occurred in eight early-onset and 10 late-onset patients. Serum albumin and cholinesterase levels prior to the start of pretransplant conditioning were significantly lower in early-onset VOD than in late-onset VOD. Multivariate analysis showed that low serum albumin levels (< or =3.7 g/dl) prior to the start of pretransplant conditioning was most strongly associated with the development of VOD. Donor mismatch (other than HLA-matched relatives), use of minocycline, and a long interval (> or =13 months) between diagnosis and BMT were also significantly associated with the development of VOD. In contrast, use of fosfomycin was associated with a decreased risk. Our data suggest that hepatic function reserve is important in the development and onset time of VOD. Veno-occlusive disease of the liver is a complication which may occur a long time after transplantation.  相似文献

BACKGROUND: Analysis of clinical characteristics of acute renal failure (ARF) after allogeneic bone marrow transplantation (BMT). PATIENTS AND METHODS: Analysis of 92 patients who developed ARF of 260 patients following BMT. RESULTS: ARF incidence was 35.4%. Sixty three percent of ARF occurred before day 20 after BMT. Duration of ARF was less of 10 days in 72.8%. ARF was non oliguric in the 80.4% of cases. Most common ARF etiologies were: multifactorial (37%), nephrotoxicity (NPH) (33.7%) and veno-occlusive disease of the liver (VOD) (14.1%). ARF secondary to VOD was the most severe: and the longest, where the secondary to NPH was less lever and shorter. Hemodialysis (HD) was necessary in 22.8% of ARF. Mortality in ARF group was 45.6%, higher in HD group (80.9%) than in non-HD group (35.2%) (p < 0.0002). CONCLUSIONS: ARF is a frequent complication following BMT. It occurs early, has short duration, is non oliguric, mainly hemodynamic and carries a whose prognosis.  相似文献

This report details the evolution of bone marrow transplantation in Europe over a 20-year period. In 1973, 8 teams undertook a total of 16 allogeneic bone marrow transplants; in 1983, 97 teams performed 1353 transplants. In 1993, the numbers had risen to 260 teams and 7737 transplants. Donor source in 3092 cases was an allogeneic donor (2464 HLA-identical sibling transplants, 147 non-identical family donor transplants, 25 twin donor transplants and 456 unrelated donor transplants). For 4645 patients the transplant was autologous (2450 autologous bone marrow transplants, 1830 autologous peripheral blood stem cell transplants and 365 combined autologous peripheral blood and bone marrow transplants). Indications for transplants in 1993 were leukemias in 3419 patients (44%; 2332 allogeneic, 1087 autologous), lymphoproliferative disorders in 2666 patients (34%; 197 allogeneic, 2469 autologous), solid tumors in 1077 patients (14%; 9 allogeneic, 1068 autologous), aplastic anemia in 251 patients (3%; 250 allogeneic, 1 autologous), inborn errors in 244 patients (3%; 242 allogeneic, 2 autologous) and miscellaneous disorders in 80 patients (1%; 62 allogeneic, 18 autologous). These data illustrate the increase of hematopoietic stem cell transplants as a therapeutic modality over the last 20 years in Europe.  相似文献

Ninety-five patients undergoing an allogeneic bone marrow transplant (BMT) and developing acute graft-versus-host disease (aGvHD) were randomized to receive low-dose intravenous 6-methylprednisolone (6MPred; 2 mg/kg /d; n = 47) or high-dose 6MPred (10 mg/kg/d; n = 48) for 5 days, with subsequent tapering doses. On day 5 patients not responding or progressing on low-dose 6MPred could be switched to high-dose 6MPred. All patients, aged 1 to 55 years, were recipients of unmanipulated BMT from HLA identical sibling donors. Patients were stratified at randomization for age (/= 20 years), disease (acute leukemia, chronic myeloid leukemia [CML], nonneoplastic disease), disease status (early/advanced), and GvHD prophylaxis (cyclosporin/cyclosporin + methotrexate). Primary endpoints were response to treatment and evolution of aGvHD to grade III-IV. Secondary endpoints were cytomegalovirus (CMV) infections, transplant-related mortality (TRM), and relapse. The median interval between BMT and treatment was 12 days (6 to 43). Results in the two groups (2 v 10 mg/kg) were as follows: response of aGvHD 68% versus 71% (P = .9), evolution to aGvHD grade III-IV 17% versus 20% (P = . 6), CMV infections 55% versus 60% (P = .7), 3-year actuarial TRM 28% versus 32% (P = .7), relapse 17% versus 7% (P = .1). The actuarial survival at 3 years was 63% versus 62% (P = .9) with a median follow up of 580 and 778 days. On day 5 of therapy, 26 patients assigned to low-dose (2 mg/kg) 6MPred were switched to a higher dose of 6MPred because of no response or progression. Their actuarial TRM was 46%, which is significantly higher than TRM of patients who responded on 2 mg/kg and continued with tapering doses (TRM = 16%, P = .007). In conclusion, early treatment of acute GvHD with 6MPred 10 mg/kg/d does not improve the response rate as compared with 2 mg/kg/d, nor does it prevent evolution to aGvHD grade III-IV. CMV infections, TRM, and survival were also comparable. A group of patients at high risk of TRM can be identified after 5 days of treatment with 6MPred 2 mg/kg and could be eligible for alternative forms of therapy.  相似文献

The purpose of this report is to review the Fred Hutchinson Cancer Research Center experience of treating patients with venocclusive disease of the liver (VOD) after marrow transplantation using recombinant human tissue plasminogen activator (rh-tPA) and heparin. The charts of 42 patients who had received rh-tPA and heparin for the treatment of VOD between February 1991 and December 1995 were reviewed. Response to rh-tPA and heparin was defined as a reduction in total serum bilirubin by 50% within 10 days of starting treatment. Total serum bilirubin, percent weight gain, and serum creatinine before, after, and at the start of rh-tPA and heparin were examined to determine whether these laboratory values distinguished patients who responded to treatment from those who did not. We also evaluated whether evidence of multiorgan failure (requirement for supplemental oxygen, requirement for hemodialysis, requirement for mechanical ventilation) or whether the calculated probability of a fatal outcome from VOD could discriminate responders from nonresponders. In addition, the incidence and outcome of bleeding as a major complication of thrombolytic therapy was examined. Twelve patients responded to rh-tPA and heparin and 30 patients did not. There were no statistically significant differences between responders and nonresponders in the day treatment was started, dose of rh-tPA, total serum billirubin, and percent weight gain before, after, or at the start of treatment, or the calculated probability of dying from VOD on the day treatment with rh-tPA and heparin was begun. More nonresponding patients required dialysis or mechanical ventilation (11 of 30) before or at the start of rh-tPA and heparin than responding patients (0 of 12), P = .0183. Serum creatinine was greater at the start of treatment in nonresponding patients (1.9 +/- 1.3 mg/dL) than in responding patients (1.1 +/- 0.4 mg/dL), P = .0794. Ten patients had severe bleeding episodes, which resulted in death in three patients and may have contributed to death in an additional three patients. Treatment for VOD using rh-tPA and heparin was successful in 29% of patients but was associated with a significant risk of life-threatening hemorrhage. Requirement for supplemental oxygen, dialysis, or mechanical ventilation before the start of treatment were prognostic indicators of no response to thrombolytic therapy. We do not recommend treatment using tPA and heparin in patients with severe VOD who have already developed multiorgan dysfunction.  相似文献

Little is known about the profile of infection with Mycobacterium tuberculosis in bone marrow transplant (BMT) recipients. Of five BMT series with a total of more than 5,000 patients, only 10 cases of M. tuberculosis infection were described, with an overall incidence of 0.19%. We have conducted a prospective evaluation of 183 consecutive BMT recipients, and 10 patients were found to develop pulmonary tuberculosis post-BMT, yielding an incidence of 5.5%. We described the clinical features of these 10 patients, and analyzed the risk factors for development of tuberculosis using age- and sex-matched case control subjects who did not develop the disease. The median age of the 10 patients who developed tuberculosis was 29 yr (range, 17 to 40 yr). The median time for onset of symptoms was 150 d (range, 23 to 550 d), mainly presenting with fever and cough, with infiltrates on chest radiograph. Respiratory tract specimens, mostly sputum, yielded positive smears for acid-fast bacilli in three and positive M. tuberculosis culture in eight, whereas lung tissue histology was the first diagnostic test in two patients. Treatment with standard antituberculosis drugs for a longer duration was highly effective, with no excessive side effects. Risk factors identified for development of tuberculosis included allogeneic BMT (p < 0.05, relative risk [RR] = 23.7), total body irradiation (p < 0. 05, RR = 4.9), and chronic graft-versus-host disease (GVHD) (p < 0. 05, RR = 3.6). It is postulated that chronic GVHD predisposed to development of tuberculosis mainly via disruption of host reconstitution of immune defenses against M. tuberculosis.  相似文献

BACKGROUND: Transplantation of blood or bone-marrow stem cells is the treatment of choice for selected patients with chronic myeloid leukaemia (CML). Transplantation is used with increasing frequency and success, but remains associated with substantial risks of morbidity and mortality. Other treatments with satisfactory short-term outcome are available. For appropriate counselling of patients, a rapid and simple way to assess risk is needed. METHODS: Data from 3142 patients (1873 [60%] male, 1269 [40%] female; mean age 34 years, range <1-60 years) treated with allogeneic blood or marrow transplants for CML between 1989 and 1997, reported to the European Group for Blood and Marrow Transplantation (EBMT), were used to develop and test a simple risk score based on previously reported major pretransplant risk factors: histocompatibility, stage of disease at time of transplantation, age and sex of donor and recipient, and time from diagnosis to transplantation. We analysed probabilities of survival, leukaemia-free survival, transplant-related mortality, and relapse incidence with respect to these risk factors. FINDINGS: At the time of analysis, 1922 (61%) of the 3142 patients were alive-1567 (65%) of those with HLA-identical sibling donors and 417 (57%) of those with unrelated donors. 1682 (54%) were alive without relapse. 1220 (39%) patients had died, 1013 (83%) of transplant-related causes, 207 (17%) of relapse. 447 (14%) patients had relapsed. The final scoring system was highly predictive for leukaemia-free survival, survival and transplant-related mortality. Survival at 5 years was 72%, 70%, 62%, 48%, 40%, 18%, and 22% for patients with scores 0, 1, 2, 3, 4, 5, and 6, respectively. Risk of transplant-related mortality was 20%, 23%, 31%, 46%, 51%, 71%, and 73%. Data showed the same trends for HLA-identical sibling transplants and unrelated transplants for transplants done in 1989-93 and 1994-96. INTERPRETATION: Pretransplant risk factors are cumulative for individual patients with CML having blood or marrow transplantation. A simple system based on five main factors gives adequate risk assessment for counselling of patients and taking decisions.  相似文献

The option of bone marrow transplantation (BMT) significantly improved prognosis of adult patients with hematologic malignancies aged less than 50 years. Allogeneic BMT using the marrow of an HLA-identical family member still provides the most effective method of BMT. Conventional indications for this form of BMT are chronic myeloid leukemia (CML), acute leukemias presenting with adverse risk factors, myelodysplastic syndromes and severe aplastic anemia. If performed early in the disease course (e.g. during the chronic phase of CML or first remission of acute leukemia and MDS) allogeneic BMT cures 50 to 60% of patients. About 20% die of therapy related complications, e.g. graft versus host disease (GvHD), fatal infections or venoocclusive disease of the liver (VOD) and about 20% of patients succumb to relapse of their hematologic disorder. 80% presenting with severe aplastic anemia can be cured, if allogeneic BMT is performed soon after diagnosis without previous immunosuppressive therapy and blood transfusions. BMT with the marrow of a matched unrelated donor or autologous BMT are increasingly used as alternative procedures. A rate of lethal complications as high as 50% hinders rapid extension of BMT with unrelated donors. Therefore, this form of BMT should be restricted to young patients with leukemias, who cannot achieve long-term remission with conventional chemotherapy (in case of acute leukemias) or alpha-interferon (in case of CML). Reconstitution of hematopoiesis is more rapid after peripheral blood stem cell transplantation (PBSCT) compared with autologous BMT. Therefore, PBSCT will replace autologous BMT in most cases. Most favourable results of PBSCT have been reported in patients with malignant lymphomas after relapse or inferior response to primary induction therapy. Due to the higher relapse rate autologous BMT is inferior to allogeneic BMT in leukemia patients. Trials are required to clarify the potential role of myeloablative therapy with stem cell support in the treatment of patients with solid tumors. Many of the preliminary results already published are unsatisfactory and data of larger trials are still lacking. Therefore, BMT or PBSCT cannot be recommended generally for the therapy of patients with solid tumors.  相似文献

Veno-occlusive disease (VOD) of the liver is a common complication of BMT and is accompanied by reduced levels of natural anticoagulants and by multi-organ dysfunction. We describe two cases of clinical VOD developing after autologous BMT and accompanied by ultrasonographic features of reversed portal venous flow. In both cases the patients had decreased levels of antithrombin (AT). Once the diagnosis of VOD was made, these patients were treated with tissue plasminogen activator (tPA) and continuous infusion AT. Each patient had radiographic and clinical resolution of VOD with the therapy. This novel treatment appears to have reversed the course of VOD without the increased risk of bleeding seen in the use of heparin therapy.  相似文献

BACKGROUND: The prognostic influences of fibrinogen and C-reactive protein levels and their relations to myocardial damage in unstable coronary artery syndromes have not been well described. METHODS AND RESULTS: Fibrinogen and C-reactive protein were determined at inclusion and related to outcome after 5 months in 965 patients with unstable angina or non-Q-wave myocardial infarction randomized to 5 weeks with low-molecular-weight heparin or placebo. The probabilities of death were 1.6%, 4.6%, and 6.9% (P=.005) and the probabilities of death and/or myocardial infarction were 9.3%, 14.2%, and 19.1% (P=.002), respectively, in patients stratified by tertiles of fibrinogen (< 3.38, 3.38 to 3.99, and > or = 4.0 g/L). The probabilities of death were 2.2%, 3.6%, and 7.5% (P=.003) after stratification of patient data by tertiles of C-reactive protein level (< 2, 2 to 10, and > 10 mg/L). In logistic multiple regression analysis, increased fibrinogen levels were independently associated with the incidence of death and/or myocardial infarction (P=.013), and elevated C-reactive protein level was associated with the incidence of death (P=.012). The increased relative risk of subsequent death or myocardial infarction in individuals with an elevated fibrinogen level was consistent in most subgroups evaluated; although significantly so only in patients with signs of myocardial damage. CONCLUSIONS: Increased levels of both fibrinogen and C-reactive protein are associated with a worse outcome in patients with unstable coronary artery disease. The increased risk associated with elevated fibrinogen levels is independent of, and additive to, the prognostic influence of myocardial damage.  相似文献

Most patients requiring allogeneic bone marrow transplantation (BMT) lack a human leukocyte antigen genotypically identical sibling and require an alternative donor. This carries an increased risk of graft failure and acute graft-versus-host disease (GVHD). We sought to overcome these problems with transplants by using grafts obtained from the most readily available source: the haploidentical, partially mismatched, related donor. This study of 40 patients used a novel approach combining in vitro and in vivo T cell depletion with T lymphocyte targeted monoclonal antibodies (mAb) and intensified conditioning therapy, including fractionated total body irradiation before etoposide, cytoside arabinoside, cyclophosphamide, and methylprednisolone. Grafts were treated with T10B9.1A-31 mAb, directed against the alpha-beta heterodimer of the T cell receptor, and rabbit complement. In vivo depletion was attempted with an anti-CD5 mAb-Ricin A-chain (H65-RTA) immunotoxin (IT). Study patients were compared with a historical control group of 17 patients not given H65-RTA. Rates of engraftment were not significantly different (93% vs. 100%, P=0.12), although patients receiving IT engrafted more rapidly. The incidence of > grade I GVHD was significantly lower in the study group (36% vs. 100%, P=0.0001), as well as for severe grade III-IV GVHD (19% vs. 92%, P=0.0001). Five-year survival tended to be improved in the study group (40% vs. 18%, P=0.21). Transplant from haploidentical family members is indicated for patients without a matched sibling in whom allogeneic BMT offers the best opportunity to achieve cure.  相似文献

BACKGROUND: Overexpression of the erbB-2 protein by breast cancer cells has been suggested to be a predictor of response to doxorubicin. A retrospective study was designed to test this hypothesis. METHODS: In National Surgical Adjuvant Breast and Bowel Project protocol B-11, patients with axillary lymph node-positive, hormone receptor-negative breast cancer were randomly assigned to receive either L-phenylalanine mustard plus 5-fluorouracil (PF) or a combination of L-phenylalanine mustard, 5-fluorouracil, and doxorubicin (PAF). Tumor cell expression of erbB-2 was determined by immunohistochemistry for 638 of 682 eligible patients. Statistical analyses were performed to test for interaction between treatment and erbB-2 status (positive versus negative) with respect to disease-free survival (DFS), survival, recurrence-free survival (RFS), and distant disease-free survival (DDFS). Reported P values are two-sided. RESULTS: Overexpression of erbB-2 (i.e., positive immunohistochemical staining) was observed in 239 (37.5%) of the 638 tumors studied. Overexpression was associated with tumor size (P=.02), lack of estrogen receptors (P=.008), and the number of positive lymph nodes (P=.0001). After a mean time on study of 13.5 years, the clinical benefit from doxorubicin (PAF versus PF) was statistically significant for patients with erbB-2-positive tumors--DFS: relative risk of failure (RR)=0.60 (95% confidence interval [CI]=0.44-0.83), P=.001; survival: RR=0.66 (95% CI=0.47-0.92), P =.01; RFS: RR=0.58 (95% CI=0.42-0.82), P=.002; DDFS: RR=0.61 (95% CI=0.44-0.85), P=.003. However, it was not significant for patients with erbB-2-negative tumors-DFS: RR=0.96 (95% CI=0.75-1.23), P=.74; survival: RR =0.90 (95% CI=0.69-1.19), P=.47; RFS: RR=0.88 (95% CI=0.67-1.16), P=.37; DDFS: RR=1.03 (95% CI=0.79-1.35), P=.84. Interaction between doxorubicin treatment and erbB-2 overexpression was statistically significant for DFS (P=.02) and DDFS (P=.02) but not for survival (P= .15) or RFS (P=.06). CONCLUSIONS: These data support the hypothesis of a preferential benefit from doxorubicin in patients with erbB-2-positive breast cancer.  相似文献

We investigated the cytokine profile and peak levels of interleukin (IL) -6, IL-8, IL-10 and tumour necrosis factor (TNF) -alpha levels in 42 patients after allogeneic bone marrow transplantation (BMT). Eleven of them developed veno-occlusive disease (VOD) of the liver. Fourteen patients had moderate-to-severe acute graft-versus-host disease (aGvHD), 10 isolated bacteraemia and 7 had no major complication. Those who developed severe VOD (n=6) showed a short, very high IL-8 peak (median: 6632 pg/ml, range: 5546-10,000 vs. 280 pg/ml, 0-2042 in controls, p<0.01) 1-4 d after diagnosis of the liver disease. Five of these patients had high peak levels of IL-6. Five patients with mild VOD showed a lower increase in the cytokines tested. Bilirubin levels, at day of IL-8 peak, did not differ statistically between mild and severe VOD. The highest levels of IL-10 were found in those with aGvHD. IL-8 levels were also increased, but not to the same extent as in patients with severe VOD (p=0.01 vs. VOD). In patients with bacteraemia, very high levels of IL-6 were seen. In patients without major complications, the levels of cytokines were low. In conclusion, high levels of IL-8 occurred in severe VOD of the liver, which may be of value to determine prognosis.  相似文献

BACKGROUND: Therapy with intravenous unfractionated heparin improves clinical outcome in patients with active thromboembolic disease, but achieving and maintaining a therapeutic level of anticoagulation remains a major challenge for clinicians. METHODS: A total of 113 patients requiring heparin for at least 48 hours were randomly assigned at 7 medical centers to either weight-adjusted or non-weight-adjusted dose titration. They were separately assigned to either laboratory-based or point-of-care (bedside) coagulation monitoring. RESULTS: Weight-adjusted heparin dosing yielded a higher mean activated partial thromboplastin time (aPTT) value 6 hours after treatment initiation than non-weight-adjusted dosing (99.9 vs 78.8 seconds; P =.002) and reduced the time required to exceed a minimum threshold (aPTT >45 seconds) of anticoagulation (10.5 vs 8.6 hours; P =.002). Point-of-care coagulation monitoring significantly reduced the time from blood sample acquisition to a heparin infusion adjustment (0.4 vs 1.6 hours; P <.0001) and to reach the therapeutic aPTT range (51 to 80 seconds) (16.1 vs 19.4 hours; P =.24) compared with laboratory monitoring. Although a majority of patients participating in the study surpassed the minimum threshold of anticoagulation within the first 12 hours and reached the target aPTT within 24 hours, maintaining the aPTT within the therapeutic range was relatively uncommon (on average 30% of the overall study period) and did not differ between treatment or monitoring strategies. CONCLUSIONS: Weight-adjusted heparin dosing according to a standardized titration nomogram combined with point-of-care coagulation monitoring using the BMC Coaguchek Plus System represents an effective and widely generalizable strategy for managing patients with thromboembolic disease that fosters the rapid achievement of a desired range of anticoagulation. Additional work is needed, however, to improve on existing patient-specific strategies that can more effectively sustain a therapeutic state of anticoagulation.  相似文献
