Lentiviral Gene Therapy with CD34+ Hematopoietic Cells for Hemophilia A.

Background: Severe hemophilia A is managed with factor VIII replacement or hemostatic products that stop or prevent bleeding. Data on gene therapy with hematopoietic stem-cell (HSC)-based expression of factor VIII for the treatment of severe hemophilia A are lacking.

Methods: We conducted a single-center study involving five participants 22 to 41 years of age with severe hemophilia A without factor VIII inhibitors.

GRAIN Study - Granulocytes Against Infections - Use of granulocyte transfusion in haematopoietic stem cell transplant.

Granulocyte transfusions (GTx) combat infections in neutropenic patients. However, immune-mediated off-target effects in transplant settings are unknown. Between January 2020 and December 2021, all transplants that used GTx during the peri-transplant period were analysed.

Total Marrow and Lymphoid Irradiation (TMLI) Is Associated with Good Early Outcomes in Patients Undergoing Matched Sibling Donor and Haplo-identical Transplants for Acute Lymphoblastic Leukemia.

Total marrow and lymphoid irradiation (TMLI) can deliver higher doses of irradiation without increased toxicity. This study evaluated TMLI and cyclophosphamide in patients undergoing stem cell transplantation for acute lymphoblastic leukemia (ALL). A total of 58 patients underwent matched related, unrelated, or haplo-identical donor transplantation using TMLI.

Impact of the COVID-19 pandemic on treatment of patients with acute myeloid leukaemia in India.

During the COVID-19 pandemic, our findings highlight changes in AML management strategies in India. There was a decrease in overall patient registrations, particularly at large referral centers, while smaller centers saw an increase, reflecting a shift towards more localized care. This shift was accompanied by a rise in the use of hypomethylating agents (HMAs).

Biomarkers of coagulation, endothelial, platelet function, and fibrinolysis in patients with COVID-19: a prospective study.

Prospective and sequential evaluation of homeostatic changes leading to thrombosis across COVID 19 disease severity spectrum are limited. In this prospective observational study, haemostasis was evaluated in patients with mild, moderate-severe, and critical COVID-19 infection. Markers of endothelial activation [Soluble thrombomodulin (sTM), von Willebrand Factor (VWF)], platelet activation [Soluble P-selectin, beta-thromboglobulin (BTG)] and global haemostasis [Rotational thromboelastometry (ROTEM)] were evaluated on days 1 and 5 after admission.

Relapse and transformation to myelodysplastic syndrome and acute myeloid leukemia following immunosuppressive therapy for aplastic anemia is more common as compared to allogeneic stem cell transplantation with a negative impact on survival.

We studied the incidence of relapse, transformation to myelodysplastic syndrome/acute myeloid leukemia, and survival in patients with aplastic anemia (AA) surviving more than 1 year after ATG/ALG-based immunosuppressive therapy (IST) between 1985 and 2020. Four-hundred seventy patients (413 adults and 57 children) were studied, and data were compared with 223 patients who underwent matched sibling donor transplant (MSD HSCT). Median follow-up is 50 months (12-359).

Haploidentical Natural Killer Cell Therapy as an Adjunct to Stem Cell Transplantation for Treatment of Refractory Acute Myeloid Leukemia.

Refractory acute myeloid leukemia (AML), defined as failure of two cycles of induction therapy at diagnosis or of one cycle at relapse, represents a subgroup with poor outcomes. Haploidentical natural killer cell (NK) therapy is a strategy that is being explored in refractory malignancies. Historically, at our center, patients with refractory AML have been treated with cytoreductive therapy (fludarabine + cytosine + granulocyte colony-stimulating factor ± idarubicin or mitoxantrone + etoposide) followed by 1-week rest and then reduced-intensity transplant with fludarabine + melphalan.

Clinical significance of end of induction measurable residual disease monitoring in B-cell acute lymphoblastic leukemia: A single center experience.

The assessment of measurable residual disease (MRD) has emerged as a powerful prognostic tool for both pediatric and adult acute lymphoblastic leukemia (ALL). This retrospective study aimed to evaluate the prognostic relevance of the end of induction MRD in B-cell acute lymphoblastic leukemia (B ALL) patients. The study included 481 patients who underwent treatment for B ALL between August 2012 and March 2019 and had their MRD at the end of induction assessed by flow cytometry.

Fludarabine-Based Low-Intensity Conditioning for Fanconi Anemia is Associated with Good Outcomes in Aplastic Anemia but not in MDS - a Single-Center Experience.

Background: Hematopoietic stem cell transplantation (HSCT) is the only curative option for patients with Fanconi Anemia (FA) with hematological abnormalities.

Materials And Methods: This is a retrospective analysis of patients with FA who underwent a matched-related donor HSCT.

Results: Sixty patients underwent 65 transplants between 1999-2021 using a fludarabine-based low-intensity conditioning regimen.

Profile and Predictors of Infection Following Anti-thymocyte Globulin or Anti-lymphocyte Globulin with Cyclosporine in Aplastic Anemia.

Immunosuppressive therapy (IST) with anti-thymocyte globulin (ATG) and Cyclosporine (CSA) in aplastic anaemia (AA) results in improvement of blood counts between 3 and 6 months for the majority of patients. Infection is the most lethal complication in aplastic anemia and may arise due to several factors. We performed this study to determine the prevalence and predictors of specific infection types before and after IST.

Hematopoietic Stem Cell Transplantation is a cost-effective alternative to enzyme replacement therapy in Gaucher Disease.

Allogeneic hematopoietic stem cell transplantation (HSCT) is a feasible treatment option for Gaucher disease (GD). Among 60 patients diagnosed with GD over 15 years (2004-2019), three children who underwent HSCT (January-November 2017) were analyzed. Two boys (cases 1 and 2) and one girl (case 3) received HSCT at 3, 7, and 10 years of age, respectively.

Decentralized manufacturing of anti CD19 CAR-T cells using CliniMACS Prodigy®: real-world experience and cost analysis in India.

Chimeric Antigen Receptor (CAR) T cell therapy is an accepted standard of care for relapsed/refractory B cell malignancies. However, the high cost of existing industry-driven centralized production makes this therapy unaffordable in low and middle-income countries. Decentralized or point of care manufacturing has the potential to overcome some of these challenges.

Molecular characterization of triple-negative myeloproliferative neoplasms by next-generation sequencing.

The role of next-generation sequencing (NGS) in identifying mutations in the driver, epigenetic regulator, RNA splicing, and signaling pathway genes in myeloproliferative neoplasms (MPNs) has contributed substantially to our understanding of the disease pathogenesis as well as disease evolution. NGS aids in determining the clonal nature of the disease in a subset of these disorders where mutations in the driver genes are not detected. There is a paucity of real-world data on the utility of this test in the characterization of triple-negative myeloproliferative neoplasms (TN-MPN).

Single Dose of Ivermectin is not Useful in Patients with Hematological Disorders and COVID-19 Illness: A Phase II B Open Labelled Randomized Controlled Trial.

Repurposed drugs may reduce morbidity and mortality in patients with hematological disorders who develop COVID-19 illness. 112 patients with predominantly hematological illnesses were randomized to receive standard of care, ivermectin 12 mg [Iv 12] or 24 mg [Iv24] for asymptomatic, mild, or moderate COVID 19 illness. Serial respiratory samples for rRT-PCR samples were sent on Day 3, 5 and 7.

Endothelial Activation and Stress Index-Measured Pretransplantation Predicts Transplantation-Related Mortality in Patients with Thalassemia Major Undergoing Transplantation with Thiotepa, Treosulfan, and Fludarabine Conditioning.

The use of thiotepa-treosulfan-fludarabine conditioning regimen and peripheral blood stem cell grafts is associated with improved outcomes of hematopoietic stem cell transplantation (HCT) in patients with high-risk thalassemia major. However, there remains a need to identify predictors of poor outcomes in this cohort to further optimize outcomes. The Endothelial Activation and Stress Index (EASIX) is a biomarker shown to predict survival in various settings, including graft-versus-host disease, veno-occlusive disease, and nonrelapse mortality following allogeneic HCT.
