Article Synopsis
  • In France, the transfusion policy for patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT) involves giving red blood cells (RBC) matching the donor's Rh type, which poses a risk of allo-immunization to both donors and recipients.* -
  • A study spanning 8 years revealed a 7.1% incidence of Rh incompatibility in 1012 alloHSCT cases, with 10.3% of evaluable patients developing alloantibodies, but none targeted the mismatched Rh antigens.* -
  • Although no immune-mediated hemolytic anemia occurred as a result of allo-immunization, a significant association was found between anti-RBC allo-immunization and

Article Synopsis
  • Late relapse (LR) after a special blood stem cell treatment for leukemia happens in about 4.5% of patients and is studied to find out how well they do after this happens.
  • A study looked at 7,582 patients who had the treatment, and 319 of them had late relapses, mostly after about 38 months.
  • The chances of living longer after a late relapse were about 19.9 months, with many patients getting better after a second treatment.

Background: Recently, the combination of venetoclax plus a hypomethylating agent (HMA; azacitidine ordecitabine) or low-dose cytarabine (LDAC) showed promise in Phase III trials in previously untreated AML. In France at the time of this study, venetoclax was not yet approved for AML and there were therefore no formal usage recommendations. Here we report the first study in a French cohort that assessed venetoclax in combination with existing treatments for AML under real-life conditions.

Background: Autoimmune conditions in B-cell lymphomas are frequent. Steroids are standard of care, but many patients require other immunosuppressive agents. Ibrutinib is a Bruton Tyrosine Kinase inhibitor that is approved for B-cell indolent lymphoma treatment.

Article Synopsis
  • Therapy resistance is a big issue in treating acute myeloid leukemia (AML), and researchers have created a 'MitoScore' to identify patients with high oxidative phosphorylation in their cells.
  • AML cells that resist treatment with cytarabine (AraC) show reliance on certain mitochondrial proteins and respond well to a combination of venetoclax (VEN) and AraC, but not to VEN with azacytidine.
  • Further research found that resistant AML cells adapt by altering their mitochondrial functions, and targeting these adaptations could improve treatment outcomes, suggesting a potential strategy to alternate between VEN therapies based on MitoScore levels to boost effectiveness.

Pure red cell aplasia (PRCA) following allogeneic haematopoietic stem cell transplantation (aHSCT) with major ABO incompatibility is responsible for transfusion dependent anaemia, impaired quality of life and iron overload. We conducted a retrospective study, over a 10-year period, which included all consecutive patients who received a major ABO mismatched aHSCT, to assess the impact of specific treatment on PRCA. We did not observe any PRCA in the 57 aHSCT issued from cord blood.

Article Synopsis
  • Scientists studied how a virus called BK can become active after certain medical treatments, especially after a type of stem cell transplant.
  • In patients who had this transplant, up to 100% could test positive for the virus in their urine, but only 5% to 40% would actually get a serious bladder issue called BKV hemorrhagic cystitis (HC).
  • The study found that certain things like being younger than 40, receiving a specific treatment called cyclophosphamide, and taking steroids could increase the chances of getting this bladder issue after the transplant.

Background: High-grade B-cell lymphoma with rearrangements of MYC and BCL2 and/or BCL6 is an aggressive mature B-cell neoplasm, whereas B-lymphoblastic lymphoma is immature cell proliferation, with a frequent positivity for terminal deoxynucleotidyl transferase. The transformation of a low-grade follicular lymphoma into a lymphoblastic neoplasm expressing terminal deoxynucleotidyl transferase is a very rare event.

Case Presentation: A 55-year-old Caucasian man was followed for a grade 1-2 follicular lymphoma carrying a t(14;18) IGH/BCL2+ and was initially treated with R-CHOP.

Red Blood Cell (RBC) transfusion dependence is a prevalent consequence of anaemia in patients with lower risk Myelodysplastic Syndromes (MDS). These patients have shorter survival compared to patients responding to Erythropoiesis-stimulating agents (ESA), raising the question of potential negative effects of chronic RBC transfusions on MDS prognosis, independently of IPSS-R. Besides commonly identified complications of transfusions like iron toxicity or cardiac events, oxidative stress could be a risk factor for ineffective haematopoiesis.

Isolated trisomy 8 (+8) is a frequent cytogenetic abnormality in the myelodysplastic syndromes (MDS), but its characteristics are poorly reported. We performed a retrospective study of 138 MDS patients with isolated +8, classified or reclassified as MDS (excluding MDS/myeloproliferative neoplasm). Myeloproliferative (MP) features were defined by the repeated presence of one of the following: white blood cell count >10 × 10 /l, myelemia (presence of circulating immature granulocytes with a predominance of more mature forms) >2%, palpable splenomegaly.
