Thrombotic microangiopathy (TMA) is a major complication after hematopoietic stem cell transplantation (HSCT). In this study, we examined the clinical and pathologic features of 2 patients and 5 autopsy cases with HSCT-associated renal TMA to clarify the association between graft-versus-host disease (GVHD) and renal TMA. The median interval between HSCT and renal biopsy or autopsy was 7 months (range 3-42 months). Clinically, acute and chronic GVHD occurred in 7 and 4 patients, respectively. Clinical evidence for TMA was detected in 2 patients, while chronic kidney disease developed in all patients. The main histopathological findings were diffuse endothelial injury in glomeruli, peritubular capillaries (PTCs), and small arteries. In addition, all cases showed glomerulitis, renal tubulitis, and peritubular capillaritis with infiltration of CD3+ T cells and TIA-1+ cytotoxic cells, suggesting that GVHD occurred during the development of TMA. Diffuse and patchy C4d deposition was noted in glomerular capillaries and PTCs, respectively, in 2 biopsy and 2 autopsy cases, suggesting the involvement of antibody-mediated renal endothelial injury in more than 50% of renal TMA cases. In conclusion, the kidney is a potential target of chronic GVHD that may induce the development of HSCT-associated TMA. Importantly, some cases are associated with chronic humoral GVHD. 相似文献

Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative treatment for some inherited disorders, including selected primary immunodeficiencies (PIDs). In the absence of a well-matched donor, HSCT from a haploidentical family donor (HIFD) may be considered. In adult recipients high-dose post-transplant cyclophosphamide (PTCY) is increasingly used to mitigate the risks of graft failure and graft-versus-host disease (GVHD). However, data on the use of PTCY in children (and especially those with inherited disorders) are scarce. We reviewed the outcomes of 27 children transplanted with an HIFD and PTCY for a PID (n = 22) or osteopetrosis (n = 5) in a single center. The median age was 1.5 years (range, .2 to 17). HSCT with PTCY was a primary procedure (n = 21) or a rescue procedure after graft failure (n = 6). The conditioning regimen was myeloablative in most primary HSCTs and nonmyeloablative in rescue procedures. After a median follow-up of 25.6 months, 24 of 27 patients had engrafted. Twenty-one patients are alive and have been cured of the underlying disease. The 2-year overall survival rate was 77.7%. The cumulative incidences of acute GVHD grade ≥ II, chronic GVHD, and autoimmune disease were 45.8%, 24.2%, and 29.6%, respectively. There were 2 cases of grade III acute GVHD and no extensive cGVHD. The cumulative incidences of blood viral replication and life-threatening viral events were 58% and 15.6%, respectively. There was evidence of early T cell immune reconstitution. In the absence of an HLA-identical donor, HIFD HSCT with PTCY is a viable option for patients with life-threatening inherited disorders. 相似文献

Reduced-intensity allogeneic transplantations for myelodysplastic syndrome (MDS) patients have been limited by significant graft-versus-host disease (GVHD), treatment-related mortality, and disease relapse. We treated 18 MDS patients ineligible for standard allogeneic transplantation with a preparative regimen of photopheresis day -7 and -6, pentostatin 4 mg/m(2) by continuous infusion day -5 and -4, and total body irradiation 600 cGy in 3 fractions day -3 and -2, followed by allogeneic stem cell infusion from 6/6 or 5/6 HLA-matched related donors or 6/6 HLA-matched unrelated donors. GVHD prophylaxis consisted of cyclosporin A and a short course of methotrexate. The median age was 54 years (range, 30-70 years). Diagnoses included refractory anemia (n = 2), refractory anemia with ringed sideroblasts (n = 2), refractory anemia with excess blasts (n = 10), refractory anemia with excess blasts in transformation (n = 3), and chronic myelomonocytic leukemia (n = 1). Sixteen of 18 patients developed full donor chimerism with no day +100 transplant-related mortality. Grade II to IV acute GVHD and extensive chronic GVHD developed in 19% and 18% of patients, respectively. Disease relapse occurred in 2 patients. At a median follow-up of 14 months (range, 1-35 months), the 1-year failure-free and overall survival were 64% and 65%, respectively. Our photopheresis and pentostatin-based reduced-intensity preparative regimen for allogeneic bone marrow transplantation in high-risk MDS patients achieves successful donor engraftment and disease remission with less transplant toxicity and grade II to IV acute GVHD. 相似文献

Sinusoidal obstruction syndrome (SOS), also known as hepatic veno-occlusive disease (VOD), is a serious complication after hematopoietic stem cell transplantation (HSCT). SOS/VOD usually occurs within 3 weeks of HSCT, but the 2016 European Society for Blood and Marrow Transplantation diagnosis criteria have been revised to include late forms. Prophylactic use of defibrotide is recommended in the pediatric setting, but its value remains uncertain in the adult population. We report here a single-center series of 63 adult patients considered at high risk for SOS/VOD who received defibrotide prophylaxis in combination with ursodeoxycholic acid between May 2012 and August 2016. The median duration of defibrotide therapy was 23 days. Bleeding occurred in 14 patients (21.5%). Defibrotide prophylaxis was discontinued in 7 patients (10.8%): 4 cases (6.3%) due to bleeding and 3 cases (4.6%) because of the need for antithrombotic therapy. Overall, SOS/VOD occurred in 4 cases (6.3%) within 21 days after HSCT (days 13 and 14) in 2 cases and late-onset SOS/VOD (days 57 and 58) in the other 2 cases. SOS/VOD was moderate in 1 case, very severe in 3 cases, with 2 deaths related to SOS/VOD. Cumulative incidence of grades II to IV acute graft-versus-host disease and transplant-associated thrombotic microangiopathy were 22.2% and 3.2%, respectively. With a median follow-up of 31 months (range, 10.7 to 60.3), the rates of 2-year overall survival, progression-free survival, incidence of relapse, and nonrelapse mortality were 56.5%, 49%, 28.7%, and 22.3%, respectively. In our experience defibrotide prophylaxis is associated with a low incidence of SOS/VOD after allogeneic HSCT in a high-risk adult population with an acceptable safety profile. 相似文献

Second-line therapies for steroid-resistant acute GVHD have been used with limited success. We have reviewed the responses of 79 hematopoetic stem cell transplant (HSCT) patients uniformly treated from 1990-1998 with equine antithymocyte globulin (ATG) for steroid-resistant acute GVHD, defined as progression of acute GVHD after 4 days of treatment with prednisone or no improvement of acute GVHD after 7 days of treatment with prednisone. Patients received HSCT from 34 related (32 matched sibling/2 partially matched) and 45 unrelated (14 HLA-A, -B, -DRB1 matched/31 partially matched) donors. Prior to ATG therapy, severe (grade III-IV) GVHD was observed in 34 patients (43%). Organs involved included skin in 81% of patients, lower GI tract in 52%, upper GI tract in 28%, and liver in 11%. Treatment consisted of 1-5 courses (median, 2 courses) of ATG (15 mg/kg per dose bid x 5 days) given for a median of 16 days (range, 5 to 44 days) after the onset of GVHD. All patients continued to receive prednisone, 60 mg/m2 per day (or methylprednisolone IV equivalent), plus CSA (75%) or tacrolimus (4%). At day 28 of treatment, overall improvement was observed in 54% of patients; durable (> or = 28 days) complete response was observed in 20% of patients, and partial response was observed in 34% of patients. In multivariate analysis, patients with CML or a malignant disease other than acute leukemia had a greater likelihood of overall response than did those with nonmalignant diseases. Patients with acute skin GVHD (with or without other organ involvement) responded most frequently. Chronic GVHD developed in 51% of patients by 1 year after HSCT. One patient developed EBV lymphoproliferative disease. For the entire cohort, the probability of survival at 1 year was 32% (95% CI, 22%-42%). In multivariate analysis, factors associated with better survival included earlier onset of acute GVHD, shorter time from initial treatment for GVHD to treatment with ATG, and the use of non-T-cell-depleted stem cell grafts. These data suggest that treatment with ATG can be an active therapy, especially in patients with skin GVHD and early signs of steroid resistance. 相似文献

Secondary myelodysplastic syndrome and acute myelogenous leukemia (sMDS/sAML) are the most serious secondary events occurring after immunosuppressive therapy in patients with aplastic anemia. Here we evaluate the outcome of hematopoietic stem cell transplantation (HSCT) in 17 children and young adults with sMDS/sAML after childhood aplastic anemia. The median interval between the diagnosis of aplastic anemia and the development of sMDS/sAML was 2.9 years (range, 1.2 to 13.0 years). At a median age of 13.1 years (range, 4.4 to 26.7 years), patients underwent HSCT with bone marrow (n = 6) or peripheral blood stem cell (n = 11) grafts from HLA-matched sibling donors (n = 2), mismatched family donors (n = 2), or unrelated donors (n = 13). Monosomy 7 was detected in 13 patients. The preparative regimen consisted of busulfan, cyclophosphamide, and melphalan in 11 patients and other agents in 6 patients. All patients achieved neutrophil engraftment. The cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 47%, and that of chronic GVHD was 70%. Relapse occurred in 1 patient. The major cause of death was transplant-related complication (n = 9). Overall survival and event-free survival at 5 years after HSCT were both 41%. In summary, this study indicates that HSCT is a curative therapy for some patients with sMDS/sAML after aplastic anemia. Future efforts should focus on reducing transplantation-related mortality. 相似文献

JAK inhibition by ruxolitinib is approved for treating myelofibrosis and also has shown efficacy in treating steroid-resistant acute and chronic graft-versus-host disease (GVHD). In 12 patients with myelofibrosis (median age, 63 years; range, 43 to 71 years) who were treated with ruxolitinib and underwent allogeneic stem cell transplantation (ASCT), ruxolitinib was continued (2 × 5?mg daily) until stable engraftment. No graft failure was observed, and leukocyte engraftment was achieved after a median of 12 days (range, 11 to 18 days). One patient developed fever of unknown origin after discontinuation of ruxolitinib; otherwise, no withdrawal syndrome was observed. Overall, only 1 patient each experienced acute GVHD grade I or II, resulting in an 8% incidence of acute GVHD grade II-IV at day +100, with no nonrelapse mortality. Complete chimerism was achieved in 11 patients after a median of 40 days, and molecular clearance of the underlying driver mutation was noted in 10 patients after a median of 32 days. Cytomegalovirus (CMV) reactivation occurred in 5 patients (41%), 1 of whom had CMV colitis as well, but all resolved after ganciclovir treatment. In 2 patients, ruxolitinib had to be discontinued on day 17 and day 18 after ASCT due to cytopenia after engraftment. Levels of inflammatory cytokines IL-8, IL-10, IL-6, TNFR2, INF-α, and INF-β were reduced after ruxolitinib treatment. After day +100, 4 patients developed acute GVHD (1 with grade I, 2 with grade II, and 1 with grade III) after tapering of cyclosporine, and all patients were alive at a median follow-up of 17 months (range, 12 to 18 months). 相似文献

Sinusoidal obstruction syndrome (SOS), also known as veno-occlusive disease (VOD), is a potentially life-threatening complication that may develop after hematopoietic stem cell transplantation (HSCT). The aims of this retrospective multicenter study were to evaluate the incidence of SOS/VOD in a large cohort of children transplanted in centers across Italy by applying the new European Society for Blood and Marrow Transplantation (EBMT) criteria and to analyze the risk factors underlying this complication. We retrospectively reviewed data of pediatric HSCTs performed in 13 AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica)-affiliated centers between January 2000 and April 2016. The new pediatric EBMT criteria were retrospectively applied for diagnoses of SOS/VOD and severity grading. Among 5072 transplants considered at risk for SOS/VOD during the study period, 103 children (2%) developed SOS/VOD, and the grade was severe or very severe in all patients. The median time of SOS/VOD occurrence was 17 days after HSCT (range, 1 to 104). Sixty-nine patients (67%) were treated with defibrotide for a median time of 16 days (range, 4 to 104). In multivariable analysis age < 2 years, use of busulfan during the conditioning regimen, female gender, and hemophagocytic lymphohistiocytosis were risk factors statistically associated with the development of SOS/VOD. The overall mortality directly related to SOS/VOD was 15.5%. Overall survival at 1 year was worse in patients with SOS/VOD (P?=?.0033), and this difference disappeared 5 years after HSCT. Nonrelapse mortality was significantly higher 1 and 5 years after transplantation in patients who developed SOS/VOD (P < .001). Based on the application of new EBMT criteria, the overall incidence of SOS/VOD recorded in this large Italian pediatric retrospective study was 2%. Nonrelapse mortality was significantly higher in patients who developed SOS/VOD. Identifying the risk factors associated with SOS/VOD can lead to more effective early treatment strategies of this potentially fatal HSCT complication in childhood. 相似文献

Allogeneic hematopoietic stem cell transplantation (HSCT) can cure transfusion-dependent thalassemia (TDT). In a multicenter trial we investigated the efficacy of reduced-intensity conditioning (RIC) before unrelated donor (URD) HSCT in children with TDT. Thirty-three children, ages 1 to 17 years, received bone marrow (BM) or umbilical cord blood (UCB) allografts. Median time to neutrophil engraftment was 13 days (range, 10 to 25) and 24 days (range, 18 to 49) and platelet engraftment 23 days (range, 12 to 46) and 50 days (range, 31 to 234) after BM and UCB allografts, respectively. With a median follow-up of 58 months (range, 7 to 79), overall and thalassemia-free survival was 82% (95% CI, .64% to .92%) and 79% (95% CI, .6% to .9%), respectively. The cumulative incidence of grades II to IV acute graft-versus-host disease (GVHD) after BM and UCB allografts was 24% and 44%; the 2-year cumulative incidence of chronic extensive GVHD was 29% and 21%, respectively; 71% of BM and 91% of UCB recipients discontinued systemic immunosuppression by 2 years. Six patients who had Pesaro risk class 2 (n?=?5) and class 3 (n?=?1) died of GVHD (n?=?3), viral pneumonitis (n?=?2) and pulmonary hemorrhage (n?=?1). Outcomes after this RIC compared favorably with URD HSCT outcomes for TDT and supported engraftment in 32 of 33 patients. Efforts to reduce GVHD and infectious complications are being pursued further. 相似文献

Posttransplantation thrombotic microangiopathy (TMA) is a multifactorial complication of allogeneic hematopoietic cell transplantation (allo-HCT) whose incidence is increased with the use of a sirolimus plus tacrolimus (SIR/TAC) regimen for acute graft-versus-host disease (aGVHD) prophylaxis. We evaluated the incidence and possible risk factors for TMA in a case series of 177 patients who received allo-HCT using SIR/TAC-based GVHD prophylaxis. The patients received either a sibling donor graft (n = 82) or a matched unrelated donor graft (n = 95). Within the first 100 days post-HCT, 30 patients (17%) were diagnosed with TMA, and an additional 9 patients (5%) were classified as probable TMA cases. The median time to onset of TMA was 4.6 weeks (range, 1.6-10.6 weeks). Thirty-four patients developed both TMA and aGVHD, with the majority (81%) developing aGVHD first. Multivariate analysis identified the following factors as associated with increased risk of TMA: day 14 serum sirolimus level ≥9.9 ng/mL (hazard ratio [HR], 2.19; 95% confidence interval [CI], 1.13-4.27; P = .02), presence of previous aGVHD grade II-IV (HR, 3.04; 95% CI, 1.38-6.71; P < .01), and fully myeloablative conditioning (HR, 3.47; 95% CI, 1.60-7.53; P < .01). These risk factors for TMA suggest that when using a SIR/TAC regimen for GVHD prophylaxis, careful monitoring and adjustment of the sirolimus dosage is critical, particularly in patients with active aGVHD. 相似文献

Tacrolimus (FK506)/mycophenolate mofetil (MMF) has been demonstrated to be an effective salvage therapy for steroid-resistant chronic graft-versus-host disease (GVHD), but its effectiveness as prophylaxis for acute GVHD (aGVHD) is unknown. We investigated the safety and efficacy of FK506/MMF in preventing aGVHD and sparing the use of methotrexate and methylprednisolone in childhood and adolescent allogeneic stem cell transplant (AlloSCT) recipients. Thirty-four childhood and adolescent patients (median age, 7 years; range, 0.5-21 years; 24 males and 10 females) undergoing 37 AlloSCTs for malignant (n = 22) and nonmalignant (n = 12) disorders received FK506 (0.03 mg/kg/d by continuous intravenous infusion) and MMF (15 mg/kg per dose orally or intravenously twice daily). Stem cell sources included 22 umbilical cord blood donors (21 unrelated and 1 related), 6 related bone marrow donors, and 9 related peripheral blood donors. Malignant diagnoses included 7 acute lymphoblastic leukemias, 3 acute myeloid leukemias, 1 acute promyelocytic leukemia, 2 non-Hodgkin lymphomas, 4 Hodgkin diseases, 3 chronic myeloid leukemias, and 2 neuroblastomas; nonmalignant diagnoses included 2 beta-thalassemias, 1 sickle cell disease, 4 aplastic anemias, 1 Wiskott-Aldrich syndrome, 1 Hurler syndrome, 2 hemophagocytic lymphohistiocytoses, and 1 myelodysplastic syndrome. The probability of developing grade > or =II aGVHD was 45.4% +/- 9.7% (7 related bone marrow/related peripheral blood; 5 umbilical cord blood), and for chronic GVHD it was 38.1% +/- 19.7%. FK506/MMF was well tolerated. Three patients had grade III to IV neurotoxicity (disorientation and leukoencephalopathy); 4 patients developed grade III to IV nephrotoxicity (all received concomitant nephrotoxins). Patients who achieved target mycophenolic acid levels (1.0-3.5 microg/mL) before day +30 had a significantly reduced incidence of developing grade >/=II aGVHD (16.7% +/- 15.2% versus 100%; P <.02). These results suggest that FK506/MMF is well tolerated and may be a safe and effective methotrexate- and methylprednisolone-sparing alternative GVHD prophylaxis regimen after AlloSCT. Further pharmacokinetic and pharmacodynamic studies are ongoing in pediatric and adolescent AlloSCT recipients to define optimal MMF dosing. 相似文献

We report on the screening and development of haploidentical hematopoietic stem cell transplantation (HSCT) for adult patients with clinically aggressive sickle cell disease (SCD) at our institution. Of 50 adult SCD patients referred for HSCT between January 2014 and March 2017, 20% were denied by insurance. Of 41 patients initially screened, 10% lacked an available haploidentical donor, 29% had elevated donor-specific antibodies (DSAs), and 34% declined to proceed to HSCT. All 10 patients who were transplanted received peripheral blood stem cells. The initial 2 were conditioned with alemtuzumab/total body irradiation (TBI) 3?Gy followed by post-transplant cyclophosphamide and failed to engraft. The next 8 patients received the regimen developed at Johns Hopkins University with TBI 3?Gy. Granulocyte colony-stimulating factor was administered from day +12 in those with HbS < 30%. All 8 patients engrafted with a median time to neutrophil >.5 × 109/L of 22 days (range, 18 to 23). One patient subsequently lost the graft, and 7 (87.5%) maintained >95% donor cell chimerism at 1-year post-HSCT. Two patients developed acute graft-versus-host disease (GVHD) of at least grade II. One had chronic GVHD and died >1 year after HSCT of unknown causes. With a median follow-up of 16 months (range, 11 to 29), 7 patients (87.5%) are alive. Our findings suggest that limited insurance coverage, high rate of DSAs, and patient declining HSCT may limit the availability of haploidentical HSCT in adult SCD patients. The modified Hopkins regimen used here demonstrates high engraftment and low morbidity rates and should be tested in larger, multicenter, prospective clinical trials. 相似文献

We previously published results for 70 children who received conditioning with treosulfan and cyclophosphamide (n = 30) or fludarabine (n = 40) before undergoing hematopoietic stem cell transplantation (HSCT) for primary immunodeficiency (PID). Toxicity was lower and T cell chimerism was better in the patients receiving fludarabine, but cohort numbers were relatively small and follow-up was short. Here we report outcomes of 160 children who received homogeneous conditioning with treosulfan, fludarabine, and, in most cases, alemtuzumab (n?=?124). The median age at transplantation was 1.36 years (range, .09 to 18.25 years). Donors included 73 matched unrelated, 54 1 to 3 antigen-mismatched unrelated, 12 matched sibling, 17 other matched family, and 4 haploidentical donors. Stem cell source was peripheral blood stem cells (PBSCs) in 70, bone marrow in 49, and cord blood in 41. Median duration of follow-up was 4.3 years (range, .8 to 9.4 years). Overall survival was 83%. No patients had veno-occlusive disease. Seventy-four patients (46%) had acute GVHD, but only 14 (9%) greater than grade II. Four patients underwent successful retransplantation for graft loss or poor immune reconstitution. Another patient experienced graft rejection and died. There was no association between T cell chimerism?>95% and stem cell source, but a significant association was seen between myeloid chimerism?>95% and use of PBSCs without an increased risk of significant GVHD compared with other sources. All 11 patients with severe combined immunodeficiency diagnosed at birth were alive at up to 8.7 years of follow-up. Long-term studies are needed to determine late gonadotoxic effects, and pharmacokinetic studies are needed to identify whether specific targeting is advantageous. The combination of treosulfan, fludarabine, and alemtuzumab is associated with excellent results in HSCT for PID. 相似文献

Adoptive immunotherapy has shown efficacy in patients with relapsed/refractory acute myelogenous leukemia (AML). We conducted a prospective evaluation of cord blood (CB)-based adoptive cell therapy following salvage chemotherapy in patients with AML or myelodysplastic syndrome (MDS) and describe the safety and early outcomes of this approach. To enhance the antileukemic effect, we selected CB units (CBUs) with a shared inherited paternal antigen (IPA) and/or noninherited maternal antigen (NIMA) match with the recipients. Furthermore, the CBUs had total nucleated cell (TNC) dose <2.5?×?107/kg and were at least 4/6 HLA-matched with the patients; a higher allele-level match was preferred. Heavily pretreated adult patients with AML/MDS were enrolled. CBU searches were performed for 50 patients. CBUs with shared IPA targets were identified for all, and CBUs with NIMA matches were found for 80%. Twenty-one patients underwent treatment (AML, primary induction failure, n?=?8; refractory relapse, n?=?10, including 7 recipients of previous allogeneic HSCT; blast crisis chronic myelogenous leukemia, n?=?1; MDS, n?=?2). Most received combination chemotherapy; those not fit for intensive treatment received a hypomethylating agent. Response was defined as <10% residual blasts in hypocellular bone marrow at approximately 2 weeks after treatment. Ten of the 19 evaluable patients responded, including 5 of the 7 recipients of previous transplant. Response was seen in 4 of 4 patients with full CBU-derived chimerism, 2 of 2 of those with partial, low-level chimerism and 4 of 12 of the recipients with no detectable CBU chimerism. The most common adverse events were infections (bacterial, n?=?5; viral, n?=?2; fungal, n = 5). Grade IV acute graft-versus-host disease (GVHD) developed in 2 patients with full CBU chimerism; 2 other patients had grade 1 skin GVHD. A total of 11 patients died, 7 from disease recurrence and 4 from infections (1 early death; the other 3 in remission at the time of death). Overall, 12 patients proceeded to allogeneic HSCT; of those, 7 had responded to treatment, 3 had not (and had received additional therapy), and 2 had persistent minimal residual disease. In conclusion, the use of CB as adoptive immunotherapy in combination with salvage chemotherapy for patients with refractory AML/MDS is feasible, can induce disease control, can serve as a bridge to allogeneic HSCT, and has an acceptable incidence of adverse events. Alloreactivity was enhanced through the selection of CBUs targeting a shared IPA and/or NIMA match with the patients. CBUs with lower cell doses, already available in the CB bank and unlikely to be adequate grafts for adult transplants, can be used for cell therapy within a short time frame. 相似文献

Conventional allogeneic hematopoietic stem cell transplantation (HSCT) for multiple myeloma is associated with high transplantation-related mortality (TRM). Nonmyeloablative allogeneic transplantation (NST) uses the well-known graft-versus-myeloma (GVM) effect to eradicate minimal residual disease. The Eastern Cooperative Oncology Group conducted a Phase II trial of autologous HSCT followed by NST to provide maximal tumor cytoreduction to allow for a subsequent GVM effect. Patients received melphalan 200 mg/m2 with autologous HSCT, followed by fludarabine 30 mg/m2 in 5 daily doses and cyclophosphamide 1 g/m2 in 2 daily doses with matched sibling donor NST. Graft-versus-host disease (GVHD) prophylaxis included cyclosporine and corticosteroids. The primary endpoints were TRM, graft failure, acute GVHD, progression-free survival (PFS), and overall survival (OS). Thirty-two patients were enrolled into the study; 23 patients completed both transplantations (72%). Best responses post-NST were 7 (30%) complete remission (CR), 11 (48%) partial remission (PR), 2 (9%) no response, and 3 (13%) not evaluable. Acute grade III-IV GVHD was observed in 4 patients (17%), and chronic GVHD was seen in 13 patients (57%; 7 limited, 6 extensive). Chronic GVHD resulted in the following responses: 3 (23%) CR, 1 continuing CR, and 6 (46%) PR. Two patients (8.7%) had early TRM. With a median follow up of 4.6 years, the median PFS was 3.6 years, and the 2-year OS was 78%. Our findings indicate that autologous HSCT followed by NST is feasible, with a low early TRM in a cooperative group setting. The overall response rate was 78%, including 30% CR, similar to other reports for autologous HSCT-NST. Because a plateau in PFS or OS was not observed with this treatment approach even in patients achieving CR, we suggest that future studies use posttransplantation maintenance therapy. 相似文献

Veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), is a life-threatening complication affecting patients undergoing hematopoietic stem cell transplantation (HSCT). The survival rate is higher when specific therapy is initiated early; thus, improving early, noninvasive diagnosis of VOD/SOS is an important need. In an adult population undergoing HSCT, we aimed to assess the role of liver stiffness measurement (LSM), evaluated by transient elastography (TE), for diagnosing VOD/SOS. Between April 2016 and March 2018, 78 consecutive adult patients with indications for allogeneic HSCT were prospectively included. LSM was performed before HSCT and at days +9/10, +15/17, and +22/24 post-HSCT. New European Society for Blood and Marrow Transplantation criteria were used to establish VOD/SOS diagnosis. Four patients developed VOD/SOS (5.1%) during the study period, with a median time of +17 days post-HSCT. A sudden increase in LSM compared with previously assessed values and pre-HSCT values, was seen in all patients who developed VOD/SOS. LSM increases occurred from 2 to 12 days before clinical SOS/VOD appearance. The VOD/SOS diagnostic performance of increased LSM over pre-HSCT assessment showed an area under the receiver operating characteristic curve of 0.997 (sensitivity 75%; specificity 98.7%). LSM gradually decreased following successful VOD/SOS-specific treatment. Interestingly, LSM values did not increase significantly in patients experiencing hepatobiliary complications (according to the Common Terminology Criteria) other than VOD/SOS. LSM by TE can be considered a promising method to perform an early, preclinical diagnosis and follow-up of VOD/SOS. 相似文献

Acute GVHD remains a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). In a retrospective analysis, the response of 443 HSCT patients who received prednisone, 60 mg/m2, for 14 days followed by an 8-week taper, as initial therapy for acute GVHD from 1990 through 1999 at a single institution was examined. Median patient age was 29.0 years (range, 0.3-60.3 years), with 40% of patients <20 years old. Patients received HSCT from 201 related (189 matched sibling/12 partially matched) and 242 unrelated (130 HLA-A, B, DRB1 matched/112 partially matched) donors. GVHD score was measured and outcomes compared using the Minnesota, Consensus, and International Bone Marrow Transplant Registry (IBMTR) grading systems. Prior to initiation of steroid therapy, severe (grades III-IV) acute GVHD was observed in 57 (13%) patients (Minnesota or Consensus grading) and in 192 (43%) patients (IBMTR grading). At day 28 of treatment, overall improvement was observed in 55% of patients, with durable (> or = 28 days) complete response observed in 35% and partial response observed in 20% of patients. Patients with acute lower gastrointestinal GVHD (+/- other organ involvement) had lower response rates. In multivariate logistic regression analysis, recipients of related donor grafts and recipients of GVHD prophylaxis other than methotrexate alone had the highest likelihood of overall response. Initial Minnesota GVHD grade or Consensus GVHD grade was not associated with significant differences in overall response, whereas patients with an initial IBMTR grade of B or C had a higher likelihood of response. Chronic GVHD developed in 42% of patients by 1 year after HSCT. The probability of survival at 1 year after initiation of steroid therapy was 53% (95% confidence interval, 48%-58%). In Cox regression analysis, factors associated with better survival included patients' youth, receipt of related or HLA-matched unrelated grafts, and administration of GVHD prophylaxis other than T-cell depletion in all 3 grading systems. Lower initial GVHD grade (I-II or A-B) led to better survival. These data suggest that steroids provide an active but inadequate therapy for acute GVHD, especially with higher grade GVHD. More effective prophylaxis and therapy for acute GVHD is needed for mismatched unrelated donor recipients and for those with severe GVHD. 相似文献

Vulvovaginal graft-versus-host disease (GVHD) is an underdiagnosed and poorly recognized complication of hematopoietic stem cell transplantation (HSCT). Previous studies have reported findings restricted to predominantly adult populations. We report a case series of pediatric and young adult vulvovaginal GVHD, which was identified in 19 patients (median age, 11.8 years; range, 2.4 to 21.9 years) out of a total 302 female patients who underwent transplantation over an 8-year period at a pediatric HSCT center. The majority of patients had concomitant nongenital GVHD; only 1 patient had isolated vulvovaginal GVHD. The median time from bone marrow transplantation to diagnosis of vulvovaginal GVHD was 30 months (range, 2.3 to 97.5 months). A high percentage of the patients in our series were without vulvar or vaginal symptoms (n = 8; 42%), even though 17 patients (89%) presented with grade 3 disease based on current adult grading scales. Vulvar examination findings most frequently included interlabial and clitoral hood adhesions (89%), loss of architecture of the labia minora or clitoral hood (42%), and skin erosions or fissures (37%). Only 5 patients underwent a speculum exam, none of whom had vaginal GVHD. Examination findings of primary ovarian insufficiency (POI) can overlap with those of GVHD, and 6 patients (32%) in our cohort were diagnosed with POI. Only 1 patient was on systemic hormone replacement therapy at the time of vulvovaginal GVHD diagnosis. The majority of patients (n = 16) were treated with topical steroid therapy, with a median time to response of 43 days. Five patients (26%) had a complete response to therapy, and 10 patients (53%) had a partial response. This case series provides valuable insight into pediatric and young adult vulvovaginal GVHD and highlights the need for increased screening for vulvar disease in this population. 相似文献

After primary recovery of platelet counts after transplantation, there can be a late persistent decline called secondary failure of platelet recovery (SFPR), which may occur although the counts of other cell lineages remain within the normal range. SFPR was defined as a decline of platelet counts below 20,000/microL for 7 consecutive days or requiring transfusion support after achieving sustained platelet counts > or = 50,000/microL without transfusions for 7 consecutive days after hematopoietic stem cell transplantation (HSCT). The study population consisted of 2871 consecutive patients receiving transplants from January 1990 to March 1997. After primary recovery of platelet counts, SFPR not due to relapse of the underlying disease was observed in 285 of 1401 (20%) patients undergoing allogeneic transplantation and 36 (8%) of 444 patients undergoing autologous transplantation, with a median time of onset after transplantation at day 63 (range, day 21-156) and day 44 (range, day 24-89), respectively. Concomitant neutropenia was seen in 57 (20%) of 285 patients undergoing allogeneic HSCT and 7 (19%) of 36 patients undergoing autologous HSCT with SFPR. By multivariable analysis, the following were factors significantly associated with SFPR after allogeneic HSCT: a transplant from an unrelated donor; a graft-versus-host disease (GVHD) prophylaxis other than methotrexate and cyclosporine; development of grade 2 through 4 acute GVHD; impaired renal or liver function; conditioning with the combination of busulfan, cyclophosphamide, and total body irradiation; stem cell dose; and infections. Cytomegalovirus infection after engraftment and source of stem cells were the only significant risk factors after autologous HSCT. The hazard rate of death was significantly higher in patients who experienced SFPR (hazard ratio = 2.6 for allogeneic HSCT; hazard ratio = 2.2 for autologous HSCT). SFPR was associated with serious complications and poor outcome after transplantation. The identification of the characteristics and risk factors for SFPR could improve patient counseling and management and lead to the design of effective treatment strategies. 相似文献
