Hematopoietic stem cell (HSC) aging correlates with an increasing risk of myeloproliferative disease and immunosenescence. In this study, we show that aging-related inflammation promotes HSC aging through tumor necrosis factor-α (TNF-α)→ERK→ETS1→interleukin27Ra (IL27Ra) pathway. TNF-α, a well-known biomarker of inflammation, increases during aging and induces the expression of IL27Ra on HSCs via ERK-ETS1 signaling.

Peking University People's Hospital & Peking University Institute of Hematology, National Clinical Research Center for Hematologic Disease, Beijing Key Laboratory of Hematopoietic Stem Cell Transplantation, No. 11 South Street of Xizhimen, Xicheng District, Beijing, 100044, People's Republic of China.

Background: Previous reports suggest a benefit associated with haploidentical donor transplantation (HIDT) compared to matched sibling donor transplantation (MSDT) in certain contexts, and the choice of optimal candidates warrants further investigation.

Methods: We designed a prospective genetically randomized study to evaluate donor options between acute lymphoblastic leukemia (ALL) patients positive for measurable residual disease (MRD) pre-transplantation who underwent HIDT (n = 169) or MSDT (n = 39).

Results: The cumulative incidence of positive MRD post-transplantation was 26% (95% CI, 19-33%) and 44% (95% CI, 28-60%) for HIDT and MSDT, respectively (P = 0.

Background: Treat-to-target strategies have improved outcomes in single-organ diseases with simple clinical or laboratory endpoints. A lack of validated endpoints has prevented adoption of treat to target for complex multiorgan conditions, such as systemic lupus erythematosus (SLE). We report the first prospective study undertaken to specifically validate a treat-to-target endpoint for SLE.

Background: Validated outcome measures are needed from which to derive treatment strategies for systemic lupus erythematosus (SLE). However, no definition of remission for SLE has been widely adopted. The Definitions of Remission in Systemic Lupus Erythematosus (DORIS) group has proposed a framework with multiple potential definitions of remission.

New approaches in allogenic transplantation in AML.

Semin Hematol

April 2019

Peking University People's Hospital & Peking University Institute of Hematology, Beijing Key Laboratory of Hematopoietic Stem Cell Transplantation, Beijing, China; Peking-Tsinghua Center for Life Sciences, Beijing, China. Electronic address:

Acute myeloid leukemia (AML) is a heterogeneous disorder with high morbidity and mortality. Allogeneic stem cell transplantation (allo-SCT) is an effective, and sometimes the only, curative postremission therapy for AML patients. Based on genetic risk classification, the published data have suggested that allo-SCT be recommended for high- and most intermediate-risk AML but not for low-risk AML in first complete remission (CR1).

This study evaluated the effects of pretransplantation minimal residual disease (pre-MRD) on outcomes of patients with acute lymphoblastic leukemia (ALL) who underwent unmanipulated haploidentical stem cell transplantation (haplo-SCT). A retrospective study including 543 patients with ALL was performed. MRD was determined using multiparametric flow cytometry.

Allogeneic stem cell transplantation (allo-SCT) is a curable method for the treatment of hematological malignancies. In the past two decades, the establishment of haploidentical transplant modalities make "everyone has a donor" become a reality. However, graft-versus-host disease (GVHD) and relapse remain the major two causes of death either in the human leukocyte antigen (HLA)-matched transplant or haploidentical transplant settings, both of which restrict the improvement of transplant outcomes.

This long-term follow-up study evaluated the effects of corticosteroid prophylaxis on graft-versus-host disease (GVHD)-free, relapse-free survival (GRFS) based on a controlled open-label randomized trial in which 228 allotransplant recipients were categorized as low risk (n = 83, group A) or high risk; patients at high risk were randomly assigned to receive (n = 72, group B) or not receive (n = 73, group C) low-dose methylprednisolone prophylaxis. The cumulative incidences of chronic GVHD, relapse, nonrelapse mortality, leukemia-free survival, overall survival, and GRFS were 60%, 19%, 16%, 68%, 73%, and 46%, respectively, in all cases. Compared with the patients in group C, the cases in group B experienced a lower cumulative incidence of moderate to severe chronic GVHD (42% versus 20%; P = .

Quantity and Quality Reconstitution of NKG2A Natural Killer Cells Are Associated with Graft-versus-Host Disease after Allogeneic Hematopoietic Cell Transplantation.

The immune mechanism underlying graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (HSCT) remains unclear. Natural killer (NK) cells play a crucial role in mediating pathogen-specific immunity and are the first donor-derived lymphocytes reconstituted post-HSCT. However, NK cells vary at different stages after HSCT.

A retrospective study (n = 460) was performed to assess the relationship between minimal residual disease (MRD) and transplant outcomes in a haplo-stem cell transplantation (SCT) setting. Patients from the pre-MRDneg group and the pre-MRDpos group had comparable outcomes. Compared to post-MRDneg patients, post-MRDpos patients had a higher incidence of relapse (100.

Article Synopsis
  • The study investigates how baseline and treatment characteristics, like age and BMI, can predict changes in bone mineral density (BMD) in postmenopausal women with osteoporosis after 1-2 years of treatment.
  • In a post hoc analysis of a clinical trial, researchers looked at the effects of two treatments (alendronate with vitamin D and calcitriol) on lumbar spine BMD over 12 months in Chinese women.
  • Results showed that factors like age, dietary calcium, and body mass index (BMI) were associated with BMD changes, indicating that different characteristics may matter for different treatments, which requires further research for confirmation.

Electronic address:

Donor lymphocyte infusion (DLI) is an effective approach to treat acute myelogenous leukemia (AML) relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) that significantly improves the survival of relapsed patients. However, the mechanism of an effective antileukemic response following DLI in AML relapse remains elusive. Here, we investigated the role of T cell exhaustion in AML relapse after allo-HSCT in prospective cohorts of 41 patients with the first AML relapse and 41 nonrelapsed AML control subjects after allo-HSCT and determined whether DLI exerts effective antileukemic effects by reversing T cell exhaustion in the relapsed cohorts by detecting the phenotypes and functions of T cells using flow cytometry.

Haploidentical stem cell transplantation (haplo-SCT) provides an alternative method to cure patients with malignant and nonmalignant hematologic diseases who lack a human leukocyte antigen (HLA) matched related or unrelated donor. HLA disparity between donor and patient was the main reason causing lots of clinical immune response. The aim of this study was to investigate whether indirect recognition of mismatched HLA could predict the clinical outcomes in haplo-SCT.

Haploidentical stem cell transplantation (haplo-SCT) has been an alternative source of bone marrow for patients without human leukocyte antigen (HLA)-matched donors. The aim of this study was to investigate the relationships between platelet transfusion refractoriness (PTR) and clinical outcomes in the setting of haplo-SCT. Between May 2012 and March 2014, 345 patients who underwent unmanipulated haplo-SCT were retrospectively enrolled.

To establish optimal reference values for recovered immune cell subsets, we prospectively investigated post-transplant immune reconstitution (IR) in 144 patients who received allogeneic stem cell transplantation (allo- SCT) and without showing any of the following events: poor graft function, grades II‒IV acute graft-versus-host disease (GVHD), serious chronic GVHD, serious bacterial infection, invasive fungal infection, or relapse or death in the first year after transplantation. IR was rapid in monocytes, intermediate in lymphocytes, CD3 Tcells, CD8 T cells, and CD19 B cells, and very slow in CD4 T cells in the entire patient cohort. Immune recovery was generally faster under HLA-matched sibling donor transplantation than under haploidentical transplantation.

Immune recovery (IR) after haploidentical stem cell transplantation (haplo-SCT) in severe aplastic anemia (SAA) patients remains relatively unknown. In this study, we examined immune cell subset counts and immunoglobulins in 81 SAA patients from day 30 to day 365 after haplo-SCT. Simultaneously, we determined which factors influence IR and analyzed the effects of immune cell subsets on transplant outcomes.
