Introduction: Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the only curative treatment option for myelofibrosis (MF). Despite the benefits of long-term relapse-free survival, HSCT can be associated with substantial treatment-related morbidity and mortality.

Methods: This is an observational retrospective study of 15 consecutive patients with MF who underwent allogeneic HSCT at a tertiary care center in Northern India between June 2012 and January 2020.

Sanjeev Kumar SharmaHematopoietic stem cell transplantation (HSCT) is the preferred treatment for high-risk and relapsed/refractory hematological malignancies. Moreover, with the improved supportive care and increasing acceptance of haploidentical transplantations as an alternative treatment modality, more patients are opting for HSCT as a definite treatment for hematological malignancies. We report here the real-world data and outcome of HSCT done for hematological malignancies at our transplant center.

COVID-19, caused by the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), was declared a pandemic by the World Health Organization on March 9, 2020. Hematopoietic stem-cell transplantation (HSCT) recipients may be highly susceptible to infection and related pulmonary complications due to nascent immune systems or organ damage from treatment-related toxicities. Poor outcomes in such group of patients were linked to older age, steroid therapy at the time of COVID-19 infection, and COVID-19 infection within a year of HSCT.

The conditioning regimens used for the allo-HSCT include either myeloablative conditioning (MAC) or reduced intensity conditioning (RIC) regimens based on the age, performance status and co-morbidities. Studies comparing the survival outcomes of RIC and MAC allo-HSCT in AML and MDS patients have reported contradictory results. We therefore retrospectively analyzed our data of AML and MDS patients who received MAC and RIC allo-HSCT at our center and compared the long term outcome of the two conditioning regimens.

We report herein haplo-identical hematopoietic stem cell transplantation (haplo-HSCT) by T-cell replete graft infusion, with post-transplant cyclophosphamide (PTCy) in patients with hemoglobinopathies. Patients received a conditioning regimen consisting of either busulfan, fludarabine, cyclophosphamide, with antithymocyte globulin or Thiotepa, antithymocyte globulin, fludarabine, cyclophosphamide, and TBI. The median follow-up period was 14.

Background: There is scarcity of data on outcome of COVID-19 in patients with hematological malignancies. Primary objective of study was to analyse the 14-day and 28-day mortality. Secondary objectives were to correlate age, comorbidities and remission status with outcome.

Hematopoietic stem cell transplantation (HSCT) is the only treatment option for the hematological manifestations of Fanconi anemia (FA). Fludarabine based reduced intensity conditioning regimens have helped in improving outcomes significantly in FA patients. We retrospectively analyzed the outcomes of FA patients who underwent allogeneic HSCT at BLK Superspeciality Hospital, New Delhi from June 2011 to September 2019.

Article Synopsis
  • Stem cell transplantation is essential for treating severe aplastic anemia patients, with a study involving 111 patients revealing that many had high-risk factors.
  • Most patients (65.7%) were identified as high-risk, with matched related donor (MRD) transplants showing better survival rates compared to haplo-identical donor (HID) transplants.
  • The overall survival rate was 67%, emphasizing the need for MRDs as the preferred option, but acknowledging HIDs as a viable alternative for life-threatening cases.

Risk of diabetes mellitus increases after solid organ and hematopoietic stem cell transplantation. Diabetic ketoacidosis has been reported after solid organ transplantation in patients receiving tacrolimus but has rarely been reported after stem cell transplantation. The major risk factors for diabetic ketoacidosis are immunosuppressive drugs used after transplantation.

Introduction: Granulocyte-colony stimulating factor (G-CSF) has been approved for use for mobilization of hematopoietic progenitor cells from the marrow into the blood for peripheral blood stem cell collection. Commonly reported side effects of G-CSF include deep throbbing bone pain, severe myalgia and leucocytosis.

Case Report: We describe a case of severe hypersensitivity anaphylactoid reaction after filgrastim administration in a healthy stem cell donor.

Cytarabine, a pyramidine analog, is used for treating various hematological malignancies such as acute leukemias and lymphomas. Side effects of cytarabine are dose dependent and include bone marrow suppression, fever, cerebellar toxicity, cardiomyopathy, hepato-renal insufficiency, necrotizing enterocolitis, pancreatitis, acute respiratory distress, corneal toxicity and dermatological side effects. The dermatological side effects can be immediate or due to delayed hypersensitivity reactions.

Thalassemia is a major public health problem in developing countries. Sibling matched hematopoietic stem cell transplantation (HCT) is the recommended treatment for thalassemia major (TM). We retrospectively analyzed our data of thalassemia major patients who underwent HCT at a tertiary care center in Northern India from January 2008 to September 2017.

Introduction: Most common source of stem cell graft for both autologous and allogenic haematopoietic transplants are peripheral blood haematopoietic progenitor stem cells. Adequate collection of the CD34+ cells and safety of the allogenic donor during the leukapheresis are of prime importance to an apheresis physician. Our retrospective analysis is a comparison between of two platforms namely, COBE Spectra and Amicus, for CD34+ mononuclear cell collection.
