Third-party fecal microbiota transplantation for high-risk treatment-naïve acute GVHD of the lower GI tract.

Disruption of the intestinal microbiome is observed with acute graft-versus-host disease (GVHD) of the lower gastrointestinal (LGI) tract, and fecal microbiota transplantation (FMT) has successfully cured steroid-refractory cases. In this open-label, single-arm, pilot study, third-party, single-donor FMT was administered in combination with systemic corticosteroids to participants with high-risk acute LGI GVHD, with a focus on treatment-naïve cases. Participants were scheduled to receive 1 induction dose (15 capsules per day for 2 consecutive days), followed by 3 weekly maintenance doses, consisting of 15 capsules per dose.

Hypoxemic Respiratory Failure Following Ruxolitinib Discontinuation in Allogeneic Hematopoietic Cell Transplantation Recipients.

Ruxolitinib, a selective inhibitor of Janus kinases 1 and 2, is increasingly being used in allogeneic hematopoietic cell transplantation (HCT) recipients following its approval by the U.S. Food and Drug Administration for the treatment of steroid-refractory acute graft-versus-host disease.

Chemotherapy-sparing treatment of haemophagocytic lymphohistiocytosis with intravenous immunoglobulins and corticosteroids.

Haemophagocytic lymphohistiocytosis (HLH) can be a rapidly fatal disease. Current treatment in adults is extrapolated from the HLH-2004 protocol that specifies a regimen of etoposide, dexamethasone and cyclosporine. However, HLH presents as a spectrum of disease severity.

Autologous stem cell transplant program in 2016-country report from Bangladesh.

We are describing eleven autologous hematopoietic stem cell transplants (ASCT) that were performed in 2016 at three different transplant centers in Bangladesh. Indications for those patients were multiple myeloma (MM) (n=4), diffuse large B cell lymphoma (DLBCL) (n=2), Hodgkin's lymphoma (HD) (n=2), peripheral T cell lymphoma (PTCL) (n=1), acute myeloid leukemia (AML) (n=1), and acute promyelocytic leukemia (APL) (n=1). All autologous stem cell products were cryo-preserved and transfused back to patients freshly thawed at 37℃.

Posttransplant cyclophosphamide in allogeneic bone marrow transplantation for the treatment of nonmalignant hematological diseases.

We present a single-center retrospective series of allogeneic bone marrow transplantation (BMT) with the use of posttransplant cyclophosphamide (PTCy) in the setting of nonmalignant hematological conditions. Nine patients were treated between 2013 and 2019. Nonmyeloablative conditioning consisted of antithymocyte globulin, fludarabine, low-dose cyclophosphamide, and total body irradiation (200cGy) followed by allogeneic bone marrow infusion.

A phase II study of reduced intensity double umbilical cord blood transplantation using fludarabine, melphalan, and low dose total body irradiation.

In this multicenter Phase 2 single arm study, we substituted low dose total body irradiation (TBI) for antithymocyte globulin (ATG) in a reduced intensity conditioning regimen with the intent to lower the risk for viral infections after double umbilical cord blood (UCB) transplantation. The conditioning regimen consisted of fludarabine (30 mg/m/day, Day -7 to -2), melphalan (100 mg/m/day, Day -1), and TBI (200cGy, Day 0). Graft-versus-host disease prophylaxis was sirolimus and tacrolimus.

Haploidentical hematopoietic cell and kidney transplantation for hematological malignancies and end-stage renal failure.

At Massachusetts General Hospital, we pioneered simultaneous hematopoietic cell (HCT)/kidney transplantation from HLA-identical related donors for the treatment of hematological malignancies with end-stage renal failure. We have now extended this to HLA-haploidentical donors in a pilot trial. Six recipients, 5 of whom were conditioned with fludarabine, cyclophosphamide, and total-body irradiation, underwent combined HCT/kidney transplantation from haploidentical donors; graft-versus-host disease (GVHD) prophylaxis included post-HCT cyclophosphamide, tacrolimus, and mycophenolate mofetil.

Twenty-year Follow-up of Histocompatibility Leukocyte Antigen-matched Kidney and Bone Marrow Cotransplantation for Multiple Myeloma With End-stage Renal Disease: Lessons Learned.

Background: Specific immune tolerance of transplanted organs in association with either transient or sustained lymphohematopoietic chimerism has been demonstrated in several preclinical animal models and clinically in patients who are full donor chimeras after hematopoietic stem cell transplantation and subsequently received kidney transplants from the same donor. Most recently, tolerance induction has been extended to patients in whom chimerism was intentionally induced at the time of kidney transplantation.

Methods: Twenty years ago, we reported the first successful histocompatibility leukocyte antigen-matched sibling donor bone marrow and kidney transplant following nonmyeloablative conditioning in a patient with multiple myeloma and end-stage renal disease (ESRD).

Peripheral Blood or Bone Marrow Stem Cells? Practical Considerations in Hematopoietic Stem Cell Transplantation.

Although peripheral blood stem cells (PBSC) have worldwide become the predominant source of progenitor cells for hematopoietic stem cell transplantation (HSCT), debate about their role compared with bone marrow (BM) has recently intensified, in large part based on the results of a multicenter Clinical Trials Network study which showed lower incidence of chronic graft-versus-host disease (cGVHD) and improved quality of life in recipients of myeloablative HLA-matched unrelated BM compared with PBSC transplants. However, in certain patient populations, PBSC may lead to improved clinical outcomes due to faster hematologic recovery, a lower risk of graft failure, and possibly a lower probability of relapse. This review will provide a comprehensive summary of studies comparing PBSC with BM as the graft source in terms of acute and chronic GVHD incidence, time to engraftment, and disease-free and overall survival probabilities after HLA-matched related and unrelated donor transplantation and haploidentical donor transplantation.

Hematopoietic Stem-Cell Transplantation in the Resource-Limited Setting: Establishing the First Bone Marrow Transplantation Unit in Bangladesh.

Purpose: Treatment of malignant and nonmalignant hematologic diseases with hematopoietic stem-cell transplantation (HSCT) was first described almost 60 years ago, and its use has expanded significantly over the last 20 years. Whereas HSCT has become the standard of care for many patients in developed countries, the significant economic investment, infrastructure, and health care provider training that are required to provide such a service have prohibited it from being widely adopted, particularly in developing countries.

Methods: Over the past two decades, however, efforts to bring HSCT to the developing world have increased, and several institutions have described their efforts to establish such a program.

Building Specialized Nursing Practice Capacity in Bangladesh: An Educational Program to Prepare Nurses to Care for Oncology and Bone Marrow Transplant Patients in Dhaka, Bangladesh.

In 2012, the Minister of Health and other leaders in the Bangladesh government approached Massachusetts General Hospital to establish the country's first bone marrow transplant program at Dhaka Medical College Hospital to serve the needs of the people of Bangladesh. Stated goals of this collaboration included a broad focus on the care of oncology patients with a specific emphasis on care of patients with hematologic malignancies and of women with gynecologic cancers. The purpose of this article is to describe the international nursing collaboration between Massachusetts General Hospital, Simmons College, the AK Khan Healthcare Trust in Dhaka, and Dhaka Medical College Hospital that was established to share nursing knowledge and to build specialized professional nursing capacities to deliver high-quality cancer care in the public sector.

Infusion of Alloanergized Donor Lymphocytes after CD34-selected Haploidentical Myeloablative Hematopoietic Stem Cell Transplantation.

Allogeneic hematopoietic stem-cell transplantation (HSCT) is a curative treatment for many hematologic cancers. Use of haploidentical (mismatched) donors increases HSCT availability but is limited by severe graft-versus-host disease (GvHD) and delayed immune reconstitution. Alloanergization of donor T cells is a simple approach to rebuild immunity while limiting GvHD after haploidentical HSCT, but the optimal T-cell dose and impact on immune reconstitution remain unknown.

Phase I Trial of Brentuximab Vedotin for Steroid-Refractory Chronic Graft-versus-Host Disease after Allogeneic Hematopoietic Cell Transplantation.

We conducted a phase I study of brentuximab vedotin (BV), an antibody-drug conjugate targeting CD30, for the treatment of steroid-refractory chronic graft-versus-host disease (cGVHD). A modified 3 + 3 study design was used with the primary endpoint to determine the maximum tolerated dose of BV in this population. Escalating doses of BV were planned, starting with .

Third-party fecal microbiota transplantation following allo-HCT reconstitutes microbiome diversity.

We hypothesized that third-party fecal microbiota transplantation (FMT) may restore intestinal microbiome diversity after allogeneic hematopoietic cell transplantation (allo-HCT). In this open-label single-group pilot study, 18 subjects were enrolled before allo-HCT and planned to receive third-party FMT capsules. FMT capsules were administered no later than 4 weeks after neutrophil engraftment, and antibiotics were not allowed within 48 hours before FMT.

Autologous Stem Cell Transplantation in Elderly Lymphoma Patients in Their 70s: Outcomes and Analysis.

Background: High-dose chemotherapy and autologous stem cell transplantation (ASCT) can offer durable remission in many patients with relapsed or high-risk lymphoma. However, elderly patients are often not considered ASCT candidates based on age alone.

Subjects, Materials, And Methods: A retrospective analysis of patients ≥70 years of age with a diagnosis of Hodgkin or non-Hodgkin lymphoma receiving ASCT between 2000 and 2016 at two partner institutions was performed.

Haematopoietic cell transplantation with and without sorafenib maintenance for patients with FLT3-ITD acute myeloid leukaemia in first complete remission.

We performed a retrospective study analysing the effect of sorafenib, an oral fms-Like Tyrosine Kinase 3 (FLT3)/multikinase inhibitor, as post-transplant maintenance in adult patients with FLT3-internal tandem duplication (ITD) acute myeloid leukaemia (AML). We identified consecutive patients with FLT3-ITD AML diagnosed between 2008 and 2014 who received haematopoietic cell transplantation (HCT) in first complete remission (CR1). Post-HCT initiation of sorafenib (yes/no) was evaluated as a time-varying covariate in the overall survival/progression-free survival (OS/PFS) analysis and we performed a landmark analysis of controls alive without relapse at the median date of sorafenib initiation.

Improved Treatment-Related Mortality and Overall Survival of Patients with Grade IV Acute GVHD in the Modern Years.

The impact of advances in supportive care and hematopoietic stem cell transplantation (HSCT) practices on the outcomes of patients who develop grade III or IV acute graft-versus-host disease (GVHD) is unknown. We performed a retrospective analysis of 427 patients with overall grade III or IV acute GVHD treated at 2 partner institutions between 1997 and 2012. We compared treatment-related mortality (TRM) and overall survival (OS) in 2 cohorts based on the year of transplantation, 1997 to 2006 (n = 222) and 2007 to 2012 (n = 205), using multivariate analysis, adjusting for significant patient-, disease-, and transplantation-related factors.

Association of acquired thrombotic thrombocytopaenic purpura in a patient with pernicious anaemia.

Pernicious anaemia is an autoimmune disease caused by intrinsic factor antibody; it leads to vitamin B12 deficiency and is marked by ineffective erythropoiesis. Haematological features reveal macrocytosis, hyperchromasia and hypersegmented neutrophils. Schistocytes are typically seen in microangiopathy, such as in thrombotic thrombocytopaenic purpura (TTP)/haemolytic uraemic syndrome or disseminated intravascular haemolysis (DIC).

Phase II Trial of Reduced-Intensity Busulfan/Clofarabine Conditioning with Allogeneic Hematopoietic Stem Cell Transplantation for Patients with Acute Myeloid Leukemia, Myelodysplastic Syndromes, and Acute Lymphoid Leukemia.

Clofarabine has potent antileukemia activity and its inclusion in reduced-intensity conditioning (RIC) allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia could potentially improve outcomes. We conducted a phase II study of busulfan (.8 mg/kg i.
