Bloodless Medicine in Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplantation.

Background: Allogeneic hematopoietic stem cell transplantation (alloHSCT) poses challenges for patients who decline blood products because of religious beliefs or other reasons. Despite potential curative prospects, many institutions refrain from offering alloHSCT to patients who decline blood products because of safety concerns associated with cytopenias.

Objectives: This review focuses on one institution's experience of conducting alloHSCT without blood components, emphasizing preparation and supportive care.

Elevated cytokines and chemokines in peripheral blood of patients with SARS-CoV-2 pneumonia treated with high-titer convalescent plasma.

The global SARS-CoV-2 coronavirus pandemic continues to be devastating in many areas. Treatment options have been limited and convalescent donor plasma has been used by many centers to transfer passive neutralizing antibodies to patients with respiratory involvement. The results often vary by institution and are complicated by the nature and quality of the donor plasma itself, the timing of administration and the clinical aspects of the recipients.

Clinical and laboratory evaluation of patients with SARS-CoV-2 pneumonia treated with high-titer convalescent plasma.

Here, we report on a phase IIa study to determine the intubation rate, survival, viral clearance, and development of endogenous Abs in patients with COVID-19 pneumonia treated with convalescent plasma (CCP) containing high levels of neutralizing anti-SARS-CoV-2 Abs. Radiographic and laboratory evaluation confirmed all 51 treated patients had COVID-19 pneumonia. Fresh or frozen CCP from donors with high titers of neutralizing Abs was administered.

Optimizing Communication and Adherence to Iron Chelation Therapy From Diagnosis to Treatment in Patients With Myelodysplastic Syndromes.

Myelodysplastic syndromes (MDS), a heterogeneous group of blood diseases, are usually diagnosed in older individuals, with a median age at diagnosis of more than 70 years. Anemia is a common symptom in patients with MDS and may require frequent red blood cell transfusions, which can lead to iron overload. Iron chelation therapy is recommended to decrease iron concentrations in tissue and minimize organ dysfunction.

The graft-versus-myeloma effect: chronic graft-versus-host disease but not acute graft-versus-host disease prolongs survival in patients with multiple myeloma receiving allogeneic transplantation.

We conducted a study of patients with multiple myeloma (MM) undergoing allogeneic transplantation to evaluate outcome parameters. Fifty-seven consecutive patients with MM received an allogeneic transplantation between 2004 and 2011 at our institution. Patients who had received at least 1 prior autologous transplantation were included.

Management of chronic graft-versus-host disease.

Chronic graft-versus-host disease (GVHD) is an immune-mediated disorder that adversely affects quality of life and clinical outcomes in patients following hematopoietic stem cell transplantation. Conventional treatment of GVHD includes prolonged and high-dose corticosteroids; however, those drugs are associated with multiple side effects. This article describes the ability of extracorporeal photopheresis therapy to exhibit a steroid-sparing effect, which can reduce long-term complications as a consequence of steroid treatment.

Unrelated donor hematopoietic stem cell transplantation for patients with hematologic malignancies using a nonmyeloablative conditioning regimen of fludarabine, low-dose total body irradiation, and rabbit antithymocyte globulin.

Hematopoietic stem cell chimerism can be established after low-dose conditioning regimens, although the risk of donor cell rejection increases for unrelated donor transplantations. We added pretransplantation rabbit antithymocyte globulin (6 mg/kg) to an established conditioning regimen of fludarabine (90 mg/m2) and single-fraction total body irradiation (200 cGy) followed by postgrafting immunosuppression with cyclosporine A and mycophenolate mofetil for 22 patients with hematologic malignancies. One patient rejected the graft and successfully underwent transplantation with cells from a second donor by using the same conditioning regimen.
