Background/aim: After allogeneic hematopoietic stem cell transplantation (allo-HSCT), donor natural killer (NK) cells trigger alloreactions against potential recipient cells by their killer immunoglobulin-like receptors (KIRs). This study investigated whether KIR/HLA genotypes and KIR haplotypes of donors and recipients exhibit a critical function in the prevalence of acute graft-versus-host disease (aGVHD) and persistence of the graft after HLA-identical sibling allo-HSCT for patients with hematological malignancies...

OBJECTIVES: Mesenchymal stromal/stem cells have immunosuppressive functions. Our previous results demonstrated that one of the players of this immunomodulation can be ascribed to the Human Leukocyte Antigen-G. HLA-G, a non classical HLA class I antigen, is involved in immune tolerance during pregnancy, organ transplantation, autoimmune and inflammatory diseases. In this study we wanted to verify whether human endometrial decidual tissue derived (EDT)-MSC could express HLA-G. Additionally we assessed the permissivity to Human Herpesvirus infections, using HSV-1 as a model, and the possible effect on EDT-MSC immunosuppressive functions towards peripheral blood mononuclear cell (PBMC) proliferation...

OBJECTIVES: After allogeneic hematopoietic stem cell transplantation (allo-HCT), urinary levels of 3-indoxyl sulfate (3-IS) correlate with the relative abundance of bacteria from the class Clostridia (RAC), and antibiotic treatment is considered the major determinant of this outcome. A high RAC has been associated with favorable outcome after allo-HCT and protection from Clostridium difficile infection (CDI). We assessed correlations between alpha diversity, RAC and urinary 3-IS levels in a non-allo-HCT clinical cohort of antibiotic treated patients to further explore 3-IS as a biomarker of reduced diversity and predisposition to CDI...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematopoietic malignancy that contributes to < 1% of all hematologic malignancies. Before the introduction of various targeted agents, the therapeutic approach was based on regimens used for acute lymphoblastic or myeloid leukemia and non-Hodgkin's lymphoma (e.g., hyperCVAD and CHOP-based regimens) followed by allogeneic stem cell transplantation for eligible patients. Given that this disease primarily affects older patients, there is a significant barrier to using these highly toxic regimens, even though these regimens are usually associated with the most durable response...

Adult T cell leukemia/lymphoma (ATL) is an aggressive peripheral T cell neoplasm, and the outcome of patients with ATL after chemotherapy is poor. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment modality for ATL, and 4 factors, namely age > 50 years, male recipient, lack of complete remission at transplantation, and transplantation of cord blood, were previously shown to be associated with poor survival. We retrospectively analyzed the outcome of 21 patients with ATL who had undergone allo-HSCT at our hospital during a 3-year period...

Autologous hematopoietic stem cell transplantation (HSCT), a safer type of HSCT than allogeneic HSCT, is a promising therapy for patients with severe autoimmune diseases (ADs). Despite the long history of medical practice, structural changes in the adaptive immune system as a result of autologous HSCT in patients with various types of ADs remain poorly understood. In this study, we used high-throughput sequencing to investigate the structural changes in the peripheral blood T-cell repertoire in adult patients with ankylosing spondylitis (AS) during two years after autologous HSCT...

The 8p11 myeloproliferative syndrome (EMS), a rare myeloproliferative disease, generally progresses rapidly and is characterized by chromosomal translocations of the fibroblast growth factor receptor 1 (FGFR1) gene. The FGFR1 gene is located at chromosome 8p11 and may fuse with distinct partner genes. The breakpoint cluster region gene located at chromosome 22 is one of these partner genes. The patients' clinical phenotype is primarily dependant on the partner gene that translocates with FGFR1. Of all the available examinations, determination of the chromosome karyotype is most essential for the diagnosis of EMS...

The aim of this study was to evaluate extramedullary (EM) relapses and its features in an allogeneic hematopoietic stem cell transplantation (alloHSCT) cohort, which consisted of patients with acute leukemia and advanced-phase chronic myeloid leukemia. One hundred and twenty-eight alloHSCT patients transplanted between the years 2001 and 2014 were analyzed. EM relapses observed in acute lymphoblastic leukemia (ALL) were more frequent than that of in acute myeloid leukemia (AML) and CML, although calculation of cumulative risk incidence, BM relapse, EM relapse, and non-relapse mortality were considered as competing risks of each other...

Few authors have reported a decreased frequency of acute graft-versus-host disease (aGVHD) using statins, as these medications have anti-inflammatory effects, however, to date, the direct association between high cholesterol and GVHD has not been reported. The aim of his study was to investigate the association of recipient and donor hypercholesterolemia with the incidence of aGVHD. A retrospective analysis was performed identifying allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients and donors at the National Institute of Medical Sciences and Nutrition in Mexico City between May 1999 and August 2017...

Cure rates for pediatric and young adult patients with refractory or recurrently relapsed acute lymphoblastic leukemia are dismal. Survival from time of relapse is typically measured in weeks to months, and standard chemotherapy and currently approved targeted therapy achieve remission in less than a third of affected patients. To date, the only definitive curative therapy has been allogeneic hematopoietic stem cell transplant (HSCT). Advances in immunotherapy, with the introduction of chimeric antigen receptor T cell therapies and the development of tisagenlecleucel, have changed the landscape...

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is potentially curative for a number of hematologic conditions, both malignant and nonmalignant. However, its success can be limited by the development of acute and chronic graft-versus-host disease (GVHD). Chronic GVHD (cGVHD) is the most common long-term complication following allo-SCT, and patients who develop this condition have significantly higher morbidity and mortality and significantly lower quality of life than patients who do not. Until recently, there were no US Food and Drug Administration (FDA)-approved therapies for cGVHD treatment...

Graft-versus-host disease-free, relapse-free survival (GRFS) is a composite endpoint that measures survival free of relapse or significant morbidity following allogeneic hematopoietic stem cell transplantation (HSCT). Consecutive 324 adult patients who received HSCT with fluarabine and busulfan based conditioning for myelodysplastic syndrome (MDS) or secondary acute myeloid leukemia evolved from MDS were retrospectively analyzed. 1-year and 3-year GRFS rates were 47.8% and 34.5%, respectively. Three fixed factors (circulating blast >3%, high cytogenetic risk, and high comorbidity index) and two factors (which is) modifiable by clinicians [myeloablative conditioning and low-dose (<7...

Vitamin A is an essential micronutrient that participates in a wide range of biological processes. Retinoic acid (RA) is an active metabolite of vitamin A that functions as an immune regulator. Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT). It is characterized by extensive inflammation arising from an alloimmune response involving various host and donor immune cells. Since vitamin A affects different immune cell lineages and regulates an array of immune responses, vitamin A, and more specifically retinoic acid, is likely to influence the incidence and/or severity of GVHD...

BACKGROUND: Acute lymphoblastic leukemia (ALL) remains one of the most difficult-to-cure hematological malignancies. Allogeneic hematopoietic stem cell transplantation (HSCT) provides curative potential but a substantial proportion of patients eventually will relapse. It is unknown if there are any modifiable factors exists that could improve survival or predict relapse immediately after HSCT is unknown. The aim of this study was to explore whether achieving early (<30 days) full donor chimerism (FDC) could predict disease relapse after allogeneic HSCT in ALL patients...

Myelodysplastic syndrome (MDS) with deletion 5q [del(5q)] is a distinct clinical and pathologic disease subset that is exquisitely sensitive to lenalidomide for the treatment of red blood cell transfusion-dependent anemia. Lenalidomide resistance, including primary resistance, occurs by clonal evolution, which is frequently attributable to the presence of somatic mutations in the DNA-binding domain of the TP53 gene. The treatment options after development of resistance to lenalidomide are limited and consist of hypomethylating agents, clinical trials, and allogeneic hematopoietic stem cell transplantation...
