Introduction: The general-purpose rating scales used by clinical pharmacists to rate their activities have not been extensively studied in specialist care units. This study aims to describe drug-related problems (DRPs) and pharmacist interventions (PIs) in a French hematopoietic cell therapy (HCT) unit and to evaluate the PIs' likely clinical, economic, and organizational impacts.

Methods: We retrospectively assessed all DRPs reported and all PIs issued between December 2018 and December 2021.

Article Synopsis
  • HSCT is the only curative treatment for patients with short telomere syndromes and severe bone marrow failure or myeloid malignancies, but the effectiveness is influenced by their sensitivity to the conditioning regimen.
  • In a study involving adults and adolescents treated with an alemtuzumab-based regimen, outcomes showed a low 2-year graft rejection-free survival (GRFS) rate for those with myeloid malignancies (20%) compared to other patients (57%).
  • While the overall 2-year overall survival (OS) was quite favorable at 66%, the findings suggest that alternative treatment strategies may be necessary for patients with myeloid malignancies.

Chimeric antigen receptor T cell (CAR-T cell) therapy has become a standard-of-care for several hematological and a promising treatment for solid malignancies or for selected non-malignant autoimmune disorders. Hematological complications following this treatment are very common with the majority of patients experiencing at least one cytopenia after CAR-T cell injections. The management of these adverse events is not standardized and represents an area of active research and unmet clinical needs.

Article Synopsis
  • The study investigates the role of Torque teno virus (TTV) load as a marker of immunosuppression in patients after allogeneic hematopoietic cell transplantation (allo-HCT).
  • Researchers analyzed TTV DNA levels in plasma samples from 70 transfusion recipients to identify factors that influence TTV load and its associations with complications and outcomes.
  • Key findings showed that higher TTV loads, especially after 90 days post-transplantation, correlated with lower overall survival and higher relapse rates, suggesting TTV load could be an important prognostic indicator.

The use of post-transplantation cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis is not established after reduced intensity conditioning (RIC) hematopoietic stem cell transplantation (HSCT) from fully matched donors. This was a randomized, open-label, multicenter, phase 2 trial. All patients received a RIC regimen with fludarabine, intravenous busulfan for 2 days (Flu-Bu2), and a peripheral blood stem cell (PBSC) graft from a matched related or 10/10 HLA-matched unrelated donor.

The use of peripheral blood (PB) or bone marrow (BM) stem cells graft in haploidentical hematopoietic stem cell transplantation with post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis remains controversial. Moreover, the value of adding anti-thymoglobulin (ATG) to PTCy is unknown. A total of 1344 adult patients received an unmanipulated haploidentical transplant at 37 centers from 2012 to 2019 for hematologic malignancy.

Pneumocystis pneumonia (PCP) is a life-threatening complication after allogeneic hematopoietic cell transplantation (allo-HCT). However, allo-HCT procedures have evolved toward older patients, unrelated donors, and reduced-intensity conditioning, possibly modifying the risks. Polymerase chain reaction (PCR), widely used nowadays, is more sensitive than microscopy diagnostic methods.

Article Synopsis
  • A multicentre retrospective study of 220 adult patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT) for therapy-related acute myeloid leukaemia (t-AML) reveals a median diagnosis age of 56 years and a significant history of prior hematological conditions or breast cancer.
  • At 12 months post-transplant, overall survival (OS) was 60.7%, event-free survival (EFS) was 52.8%, and graft-versus-host disease-free relapse-free survival (GRFS) was 44.1%; 44% of patients achieved complete remission by last follow-up.
  • The study indicates that uncontrolled t-AML at the time of transplant negatively impacts E

In this registry-based study we retrospectively compared outcomes of allogeneic hematopoietic cell transplantation (allo-HCT) for adult patients with acute lymphoblastic leukemia (ALL) following conditioning with total body irradiation (TBI) combined with either cyclophosphamide (Cy) or fludarabine (Flu). TBI 12 Gy + Cy was used in 2105 cases while TBI 12 Gy + Flu was administered to 150 patients in first or second complete remission. In a multivariate model adjusted for other prognostic factors, TBI/Cy conditioning was associated with a reduced risk of relapse (HR = 0.

Letermovir is the first approved drug for cytomegalovirus (CMV) infection prophylaxis in adult patients who are CMV positive undergoing allogeneic hematopoietic cell transplantation (allo-HCT). Because CMV infection risk varies from patient to patient, we evaluated whether a risk-based strategy could be effective. In this single-center study, all consecutive adult patients who were CMV positive and underwent allo-HCT between 2015 and 2021 were included.

Article Synopsis
  • - The article defines and discusses three key complications after hematopoietic cell transplantation (HCT): graft failure, poor graft function, and erythroblastopenia, highlighting the associated risk factors and treatment guidelines.
  • - Graft failure is a severe but rare complication, while poor graft function occurs more frequently; new research is anticipated to validate current treatment recommendations for these issues.
  • - Erythroblastopenia is another rare complication post-HCT, and even with improved donor-recipient compatibility, some patients still experience this problem.

Article Synopsis
  • About 10-30% of adults with primary mediastinal B cell lymphoma (PMBCL) either don't respond to treatment or relapse early, making allogeneic stem cell transplantation (allo-HSCT) a potential curative option.
  • A study examined 33 PMBCL patients who underwent allo-HSCT between 1999 and 2018, revealing that 42% had sibling donors and that patients had varying responses to prior treatments.
  • The findings reported a 2-year overall survival rate of 48% and suggested that the disease status at the time of transplant significantly affected survival outcomes, with a possibility of durable remissions after 4 years for some patients.

Relapse is a major cause of treatment failure after allogeneic hematopoietic cell transplantation (allo-HCT) in myeloid malignancies. Additional strategies have been devised to further maximize the immunologic effect of allo-HCT, notably through maintenance therapy with hypomethylating agents such as 5-azacytidine (AZA). We conducted a single-center retrospective study to investigate the efficacy of AZA after allo-HCT for high-risk myeloid malignancies.

Adoptive transfer of gene-engineered chimeric antigen receptor (CAR)-T-cells has emerged as a powerful immunotherapy for combating hematologic cancers. Several target antigens that are prevalently expressed on AML cells have undergone evaluation in preclinical CAR-T-cell testing. Attributes of an 'ideal' target antigen for CAR-T-cell therapy in AML include high-level expression on leukemic blasts and leukemic stem cells (LSCs), and absence on healthy tissues, normal hematopoietic stem and progenitor cells (HSPCs).

After chemotherapy, fewer than 30% of patients with T-cell lymphoma (T-NHL) are long-term disease-free survivors. Thus, there is a growing interest in allogeneic stem cell transplantation (alloSCT) and its potential graft-versus-lymphoma effect (GVL) for patient with high-risk or recurrent T-NHL with the aim at providing durable disease control in T-NHL. We conducted this registry study to evaluate the outcome of recipients of alternative donor alloSCT for T-NHL.
