Summary: Leukocyte adhesion deficiency type I (LAD-I) is a rare genetic immune disorder that can be cured with allogeneic hematopoietic cell transplant (HCT). In cases where ideal donors are unavailable, HLA-haploidentical HCT with posttransplant cyclophosphamide (PT-CY) can be a safe and effective alternative.

Summary: Post-transplantation cyclophosphamide (PTCy) is a drug used to treat graft-versus-host disease (GVHD) following hematopoietic cell transplantation (HCT). It works by impairing and suppressing antigen-specific T cells. In this study, reduced proliferation of CD4(+) T cells at day +7 and preferential recovery of CD4(+)CD25(+)Foxp3(+) regulatory T cells (T-regs) at day +21 were identified as potential biomarkers associated with optimal PTCy dosing and timing.

Summary: The study suggests that a low CD4/CD8 ratio during HIV treatment is associated with immunosenescence. Data analysis shows that patients with a CD4/CD8 ratio less than 0.3 in the second year of ART have an increased risk of developing SNAEs in the next five years.

Summary: The loss of patient-specific HLA after haploidentical hematopoietic stem cell transplantation is considered a relapse mechanism affecting graft-versus-leukemia (GVL) effects. Blinatumomab showed promising results in treating patients with HLA loss relapse, with most patients achieving complete remission or partial recovery within the first treatment cycle and meeting the primary endpoint within 2 cycles. Adverse effects included cytokine release syndrome, cytopenias, and elevated liver enzymes. Further studies are needed to assess the efficacy of blinatumomab in this patient population.

Summary: This study reported on a patient with refractory hepatosplenic & gamma;& delta; T-cell lymphoma who achieved complete remission and maintained it after receiving HLA fully-mismatched sibling-derived CD7 CAR-T therapy followed by haploidentical hematopoietic stem cell transplantation. This is the first case of its kind, highlighting the potential of CAR-T therapy and haploidentical HSCT in treating relapsed/refractory T-cell lymphoma.

Summary: In this retrospective analysis, allogeneic hematopoietic stem cell transplantation (allo-HSCT) did not show a significant survival advantage compared to standard-of-care regimens in patients with stage IV alveolar rhabdomyosarcoma (RMA). Individualized treatment strategies and disease status are important factors in determining patient survival.

Summary: Despite the current treatment for high-risk neuroblastomas (HR-NB), the 5-year overall survival rate remains low. There is a need to improve the standard therapeutic protocol, particularly in enhancing the immune response against the tumor.

Summary: Cytokine release syndrome (CRS) is common in HLA-haploidentical hematopoietic stem-cell transplantations, but initiating cyclophosphamide along with cyclosporine and mycophenolate mofetil can reduce CRS without increasing the risk of graft-versus-host disease (GVHD). The study showed a high disease-free survival rate at day 100 and a moderate overall survival rate at 3 years.

Summary: Basiliximab is safe and effective for treating steroid-refractory acute graft-versus-host disease (SR-aGVHD). Combined therapy does not improve the treatment response and may increase the risk of infection. Various factors are associated with the therapeutic response, leading to the development of a prognostic scoring system.

Summary: In this study, we analyzed clinical data from 278 patients with chronic myeloid leukemia (CML) and found significant correlations between blood and/or bone marrow blasts, blood basophils, age, platelet concentration, and patient survival and transformation-free survival (TFS). Based on these factors, patients were classified into low, intermediate, and high-risk groups, with significant differences in survival and TFS between the groups. Additionally, 2G-TKI treatment showed better cytogenetic and molecular responses compared to imatinib.

Summary: This study compared the efficacy and safety of haplo-HSCT in B-cell ALL patients with suboptimal MRD response after reinduction who underwent CAR-T therapy or chemotherapy. The results showed that patients in the CAR-T group had a significantly lower median pre-HSCT MRD level compared to the chemotherapy group. The CAR-T group exhibited improved 3-year leukemia-free survival and overall survival, with no increased risk of complications.

Summary: Previous studies have shown that TP53 mutation is associated with insufficient therapy response and unfavorable prognosis in acute lymphoblastic leukemia (ALL). However, a new study suggests that TP53 mutation may not impact survival in ALL patients after haploidentical hematopoietic stem cell transplantation (haplo-HSCT).

Summary: CD34(+) cell dose has an impact on hematopoietic recovery in ALL patients, especially in pre-HSCT MRD-positive patients, where higher CD34(+) cell doses are associated with faster neutrophil and platelet engraftment. However, we did not observe direct correlations between CD34(+) cell dose and relapse, TRM, LFS, or OS.

Summary: This study found that glycolysis plays a critical role in T cell activation and induction of human aGvHD. Regulating glycolysis offers a potential pathogenesis-oriented therapeutic strategy for aGvHD patients, and the combination of GCs and glycolysis inhibitors may be a novel first-line combination therapy for aGvHD patients.

Summary: This study compared the clinical outcomes of AML patients with and without TP53 mutations who underwent haplo-HSCT, and found no significant differences in 2-year clinical outcomes between the two groups. Multivariable analysis also showed that TP53 mutations had no significant impact on relapse rate, mortality rate, overall survival, graft-versus-host disease, leukemia-free survival or GvHD-free/relapse-free survival. The findings suggest that patients with AML with TP53 mutations may at least partially benefit from haplo-HSCT.

Summary: This study found that EVI1 high expression was associated with poor prognosis in the Non-KMT2A-MLLT3 group and both KMT2A-MLLT3 and Non-KMT2A-MLLT3 patients who received chemotherapy alone had poorer prognosis than those who received allogeneic hematopoietic stem cell transplant. High EVI1 expression was shown to have an adverse effect on AML with KMT2A rearrangement in different risk stratification subtypes.

Summary: The patterns of hepatitis B virus reactivation (HBV-R) in HBsAg (-)/HBcAb (+) patients with B-cell non-Hodgkin lymphoma (NHL) receiving rituximab based immunochemotherapy have not been well described. The study found a high incidence of HBV-R and high mortality after HBV-R in HBsAg (-)/HBcAb (+)/HBeAg (-)/HBeAb (+) patients with B-cell NHL, suggesting the need for prophylactic antiviral therapy.

Summary: In allogeneic hematopoietic cell transplantation, reconstitution of virus-specific T cells and leukemia-specific T cells is crucial for patient protection. Cytomegalovirus (CMV) infection is a significant cause of morbidity and mortality after transplantation. Recent data suggests that CMV reactivation is associated with a reduced risk of leukemia relapse in AML patients. Our study found that CMV-specific CD8+ T cells reconstituted faster than WT1-specific CD8+ T cells. Furthermore, CMV-specific T cells exhibited lower exhaustion markers and higher functionality compared to WT1-specific T cells. Notably, patients with CMV reactivation had a higher frequency of CMV-specific T cells and different expression patterns of Eomes and T-bet compared to patients without CMV reactivation. The kinetics of CMV-specific and WT1-specific T cell reconstitution may be associated with measurable residual disease and leukemia relapse. These findings suggest that CMV reactivation may influence WT1-specific T cell reconstitution after allo-HSCT, potentially affecting the remission/relapse of AML.
