The aim of this study was to investigate the relationship between the plasma levels of chemokine CCL-2/MCP-1 and acute graft-versus-host disease (aGVHD) and/or idiopathic pneumonia syndrome (IPS) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). ELISA assays were used to detect the plasma level of CCL-2/MCP-1 of 22 patients who received allo-HSCT, including 14 patients without or with grade I, 8 patients with grade II - IV aGVHD, respectively. 8 out of 22 patients were also diagnosed with IPS clinically. The dynamic changes of the plasma levels of CCL-2/MCP-1 chemokine and its correlation with aGVHD and/or IPS were analysized retrospectively. The results showed that the plasma levels of CCL-2/MCP-1 in the patients with moderate and serious aGVHD (grade II - IV) significantly increased, as compared with that prior to allo-HSCT (p < 0.05). The plasma levels of CCL-2/MCP-1 in the patients with aGVHD and/or IPS were higher significantly than those without any of these complications (p = 0.001). The retrospective analysis indicated that the plasma levels of CCL-2/MCP-1 in the patients with IPS significantly increased (p = 0.006). It is concluded that plasma level of CCL-2/MCP-1 correlates with aGVHD and/or IPS, and plays a role in the pathogenesis of these complications.

OBJECTIVEBased on the 2002 WHO health survey data, to explore the latent relationship among self-reported health level, the actual level of health, the social demographic characteristics and the risk factors, and to analyze the influence of the various surveillance indicators on self-reported health and the degree that the self-reported health explained the actual level of health.

METHODSField tests for various components of the World health survey were conducted in nine countries during 2002, including India, Brazil, Burkina, Hungary, Nepal, Russia, Spain, Tunisia, and Vietnam (29 971). The survey questionnaire included a self-assessment component and anchoring vignette component. The self-assessment component data was adjusted and eliminated the affect of "cut-point bias" by using the anchoring vignette component data, and then was used to build the structural equation model on the relationship among self-reported health level, actual health level, social demographic characteristics and the risk factors.

RESULTSIn the final structural equation model, "the actual level of health" = 0.80 × "the self-reported health level" + (-0.04) × "the social demographic characteristics" + (-0.08) × "the risk factors" (R(2) = 0.66), and "the self-reported health level" = (-0.70) × "the social demographic characteristics" + 0.10 × "the risk factors" (R(2) = 0.55). The standardized total effect of self-reported health to the actual level of health was 0.80, and that of the social demographic characteristics to the self-reported health and the actual level of health were -0.70 and -0.60, respectively. And the 16 items of self-reported health consisted of 8 dimensions; and sorted by the power of impact to the actual health level, they were mobility, pain and discomfort, sleep, cognition, feelings, self-care ability, visual capacity and interpersonal activities.

CONCLUSIONThere were significant linear correlation relationship between the actual level of health and the self-reported health, as well as between the self-reported health and the social demographic characteristics. And the self-reported 16 items used by the 2002 WHO health survey played an important role in the health evaluation of population.

BACKGROUNDWide application of umbilical cord blood transplantation (UCBT) in adult patients is limited by low cell-dose available in one umbilical cord blood (UCB) unit. The aim of this study was to investigate the safety and long-term outcomes of UCBT from unrelated donors in adult and adolescent patients with leukemia.

METHODSThirteen patients with leukemia received double-unit UCBT with human leukocyte antigen (HLA) mismatched at 0 - 2 loci. We analyzed the engraftment, graft-versus-host disease (GVHD) and survival.

RESULTSTwelve evaluable patients (92.3%) had neutrophil and platelet engraftment at a median of 21 days (range, 16-38 days) and 34 days (range, 25 - 51 days), respectively. At day 30, engraftment was derived from one donor in 8 patients (66.7%, 95%CI 40.0% - 93.4%), and from both donors in 4 patients (33.3%, 95%CI 6.7% - 60.0%) with 1 unit predominated. Unit with larger nucleated cell (NC) dose would predominate in engraftment (P = 0.039), whereas CD34(+) cell dose or HLA-match failed to demonstrate any relationship with unit predominance. Only one patient developed grade II acute graft-versus-host disease (aGVHD). Chronic GVHD (cGVHD) was observed in 2 of 11 patients who survived more than 100 days, and both were limited. The median follow-up after transplantation for the 13 patients was 45 months (range 1.5 - 121.0 months) and 72 months (range 41.0 - 121.0 months) for the 8 alive and with full donor chimerism. The 5-year cumulative disease free survival (DFS) was (61.5 ± 13.5)%. Of the 13 patients, 5 patients died in 1 year and 1-year transplantation related mortality (TRM) was 23.1% (95%CI 0.2% - 46.0%).

CONCLUSIONDouble-unit UCBT from unrelated donors with HLA-mismatched at 0-2 loci may overcome the cell-dose barrier and be feasible for adults and adolescents with leukemia.

OBJECTIVETo observe the engraftment, survival and graft-versus-host disease (GVHD) after 2 units unrelated cord blood (UCB) transplantation for treatment of adult hematological malignancies.

METHODSAmong twelve patients with hematological malignancies, ten were in stable stage and 2 in advanced stage. Conditioning regimen was Bu/Cy or Cy/TBI in 11 cases, and 1 received nonmyeloablative regimen. Antithymocyte globulin (ATG) was administered in all patients. GVHD prophylaxis consisted of cyclosporine A (CsA), mycophenolate mofetil (MMF) and short course methotrexate (MTX). Each patient received 2 units UCB of HLA mismatched at 0 -2 loci. Median total nucleated cells (TNC) infused was 5.55 x 10(7)/kg [range (2.99 -8.18) x 10(7)/kg].

RESULTSOne patient showed primary graft failure. The other 11 patients showed neutrophil engraftment at a mean time of (21.6 +/- 5.1) days and platelet engraftment at (34.9 +/- 9.5) days. One patient showed secondary graft failure and died of leukemia relapse at 3 months after transplantation. Ten patients (83.3%) gained sustained engraftment. In 9 patients the UBC unit with larger TNC dose predominated engraftment, and only 1 patient showed the unit with smaller TNC predominated (P = 0.011). Acute GVHD was observed in 6 patients, including grade I in 5 and grade II in 1. Limited chronic GVHD was observed in 2 of 10 patients survived more than 100 days. Of the total 12 patients, eight were still alive in event-free status and 3-year event-free survival(EFS) was (66.7 +/- 13.6)%. Of the 10 patients in stable stage at the time of transplantation, the probability of EFS was (70.0 +/- 14.5 )%.

CONCLUSIONSTwo UBC units transplantation with HLA mismatched at 0 - 2 loci is feasible as a treatment modality for adult hematological malignancies, and the unit with larger TNC dose would predominate the engraftment.

The study was aimed to investigate the incidences and risk factors of acute and chronic graft-versus-host diseases (GVHD) and to clarify their effects on relapse and survival of recipients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The clinical data of 100 cases of allo-HSCT were retrospectively analyzed. The incidences and risk factors of aGVHD and cGVHD, relapse and survival were studied. The results showed that 31 cases developed aGVHD of II - IV grade (34.4%) and 14 cases developed aGVHD of III - IV grade (17.7%). HLA matched or mismatched did not show significant difference in the development of aGVHD of II - IV grade (p > 0.05). Previous occurrence of aGVHD was the risk factor for cGVHD (HR = 2.303, p = 0.088). The female was a favorable factor for cGVHD (HR = 0.401, p = 0.055). The relapse rate was lower in patients who developed cGVHD. The development of aGVHD of II - IV grade was the risk factor for overall survival (p < 0.05). The mortality of patients with aGVHD of III - IV grade and mortality of patients with aGVHD of 0 - I grade were 81.0% and 35.7% respectively, there was very significant difference between them (p = 0.000). In conclusion, till now GVHD and graft-versus-leukemia (GVL) effect can not be separated. The positive effect of GVL could be counteracted by GVHD-related mortality. It is necessary to prevent and control the development of severe aGVHD. The development of local cGVHD may be beneficial to the long-term disease-free survival of patients after allo-HSCT.

OBJECTIVETo investigate the treatment of primary amyloidosis with high-dose melphalan and autologous hematopoietic stem cell transplantation to further examine the survival, hematologic response, and improvement of amyloid-related organ dysfunction.

METHODSRetrospective analysis of 20 patients with primary amyloidosis treated with autologous hematopoietic stem cell transplantation. The status of major organ function before transplantation, mobilization programs and conditioning regimen as possible risk factors for survival were also investigated.

RESULTSOf 20 cases, 11 out of 15 evaluable cases achieved hematologic response, among them, 6 got complete remission (CR, 40%) and 5 partial remission (PR, 33%). The median onset time was 3.0 months (1.5 - 4.0 months) and 4 months (3 - 5 months), respectively after transplantation. The overall hematologic response was 73%. The 11 hematologic responders also had kidney responses. The median time to achieve kidney response was 3 months (2 - 6 months). The 3-year overall survival of the cohort of cases was 71.4%. The major causes of death were heart failure, renal dysfunction and gastrointestinal bleeding. G-CSF alone could obtain satisfactory mobilization results and most of patients well tolerated to the conditioning regimen of melphalan doses from 140 mg/m(2) to 200 mg/m(2).

CONCLUSIONTreatment of primary amyloidosis with high-dose melphalan followed by autologous peripheral blood stem cell transplantation produced high efficacy. The cardiovascular system involvement, renal dysfunction and the abnormality of coagulation function before transplantation may be the risk factors for survival.

OBJECTIVETo investigate the efficacy and treatment outcome of different induction regimens, and different post-remission therapies for adult acute promyelocytic leukemia (APL).

METHODSThe outcome of 73 patients with newly diagnosed APL were retrospectively analyzed. According to the induction regimens, the patients were divided into three groups: chemotherapy-only (14 cases group I), all-trans retinoic acid (ATRA) or combined with chemotherapy (33 cases group II), and ATRA combined with arsenic trioxide (As(2)O(3)) (26 cases group III). The complete remission (CR) rate and the time to CR (TTC) were analyzed. After CR, the patients were divided into 2 groups for post-remission therapies: one with sequential treatment of chemotherapy/ATRA/As(2)O(3) and the other with alternative treatment of chemotherapy/ATRA. The overall survival (OS), disease free survival (DFS) and relapse rate were compared between these two groups. Patients induced CR with both ATRA and As(2)O(3), and then sequentially treated with chemotherapy/ATRA/As(2)O(3) (group A), and those induced CR with ATRA or As(2)O(3) alone and then with non-chemotherapy/ATRA/As(2)O(3) sequentially (group B) were also analyzed and compared for CR, OS and DFS.

RESULTS(1) For induction treatment, the CR rate in ATRA and As(2)O(3) combination group was 100%, in ATRA combined with chemotherapy group was 78.8%, and in chemotherapy-only group was 57.1% (P = 0.030). The median TTC in ATRA with As(2)O(3) combination group was 26 (13 - 40) days being the shortest among the three groups. (2) For the post-remission treatment, 3-year OS rates in group I and group II were (95.7 ± 4.3)% and (68.6 ± 11.2)% (P < 0.05), and 3-year DFS rates were (79.0 ± 9.5)%, and (32.9 ± 15.5)%, respectively (P < 0.01). The relapse rate was 14.8% in group I, and 50.0% in group II (P = 0.011). (3) The CR, 3-year OS and DFS rates in group A were all 100%. The CR rate in ATRA or As(2)O(3) alone induced group was 72.9%, and 3-year OS was (72.3 ± 9.1)% (P < 0.05).

CONCLUSIONSFor adult APL induction with ATRA and As(2)O(3) combination can obtain a higher CR rate, and shorter TTC. The post-remission treatment with sequential chemotherapy, ATRA and As(2)O(3) results in a lower relapse rate, and significantly improves OS and DFS. The ATRA and As(2)O(3) combination induction with the sequential post-remission therapy is the best strategy for APL treatment.

OBJECTIVETo analyze the impact of the time to hematopoietic reconstitution on the prognosis of hematological malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS173 patients with hematological malignancies treated with allo-HSCT (excluding umbilical cord blood transplantation) at Peking University first Hospital between 2003 and 2011 were analyzed retrospectively. According to the median time to neutrophil and platelet engraftment, the patients were divided into tow groups. The 5-year overall survival (OS), transplant-related mortality (TRM), relapse rate (RR) and prognostic factors were analyzed.

RESULTSThe quicker neutrophil engraftment group with an estimated 5-year OS rate of 66.63%, 5-year TRM of 21.58% and 5-year RR of 18.65%. The slower neutrophil engraftment group with OS of 61.84%, TRM of 24.14% and RR of 23.57%. Univariate analysis demonstrated that no relationship was found between time to neutrophil engraftment and OS, TRM and RR (P = 0.462, P = 0.893, P = 0.545, respectively). There seems to be a trend toward increasing incidence of OS in quicker platelet engraftment group(OS were 69.44% and 54.31%, respectively), but no significant difference (P = 0.065). TRM were 19.13% and 25.45%, respectively (P = 0.424), RR were 17.36% and 24.71%, respectively (P = 0.251). Multivariate analyses showed that the time to neutrophil engraftment was not a significant risk factor for prognosis, the time to platelet engraftment was an independent risk factor for OS and TRM, but not a significant risk factor for RR. Pre-transplantation disease status was the only independent prognostic factor for RR.

CONCLUSIONSThe time to platelet engraftment was a significant predictor after allo-HSCT. Early platelet engraftment increased OS, which this may be due to decreasing TRM.

OBJECTIVETo study the chronic health conditions (CHC) in long-term survival recipient after hematopoietic stem cell transplantation (HSCT).

METHODSThe CHC of 101 cases survived for more than 1 year after HSCT were collected according to Bone Marrow Transplant Survivor Study (MBMTSS) questionnaire. The differences of the incidence and severity of CHC between auto-HSCT and allo-HSCT, HLA-matched and HLA-mismatched family donors HSCT were compared, and risk factors related to chronic health conditions were analyzed retrospectively in family donor HSCT.

RESULTSOf the 101 HSCT survivors, 48.5% reported one or more chronic health conditions, and 83.7% of which were mild to moderate. The CHC in HLA-matched related donors HSCT were more serious than in HLA-mismatched related donors HSCT. The percentage of CHC total score above 3 in allo-HSCT recipients (32.1%) was higher than that in auto-HSCT ones (10.0%). The percentage of CHC total score 1-2, 3-4, and above 5 in HLA-matched family donors HSCT were 23.5%, 29.4%, and 14.7%, respectively, being significantly higher than those in HLA-mismatched ones (15.6%, 15.6%, and 6.2%, respectively). CHC was mainly related to chronic graft-versus-host disease (cGVHD). Single variable analysis showed that younger age at time of transplantation, HLA fully matched, the use of antithymocyte globulin (ATG) in the conditioning regimens were favorable for CHC. COX-regression Model showed that age was the only independent risk factor for predicting the CHC in family donor HSCT.

CONCLUSIONThe chronic health conditions after HSCT is mild to moderate, these complications in HLA-matched related donor HSCT are more serious than those in HLA-mismatched related donor HSCT. The age at transplantation is the only independent risk factor for chronic health conditions.
