Immunosuppressive therapy (IST) using horse antithymocyte globulin (h-ATG) combined with cyclosporine (CsA) and eltrombopag is the standard care for aplastic anemia (AA) in patients without a suitable matched donor. However, in many countries, h-ATG use has been discontinued, leaving rabbit ATG (r-ATG), which has a lower response rates and poorer survival, as the only alternative. In previous studies, alemtuzumab (ALZ), a humanized monoclonal antibody targeting CD52, combined with CsA resulted in an adequate ORR in AA patients.

Background Aplastic anemia (AA) is a rare and heterogeneous hematological disorder defined as pancytopenia with hypocellular bone marrow in the absence of abnormal infiltration or medullary fibrosis. Various causes of AA have been identified, such as autoimmune factors, bone marrow injuries, viral infections, and genetic disorders. The symptoms of AA are directly linked to pancytopenia and the most common are fatigue, recurrent infections, and bleeding problems.

Introduction: Aplastic anaemia (AA) is a rare disorder of bone marrow failure, characterized by bone marrow hypocellularity with pancytopenia. The annual incidence rates of AA in Asia are observed to be two to three times higher than Europe and North America. Since the introduction of immunosuppressive therapy (IST) and of allogenic stem cell transplant (SCT), the outcome of severe AA has significantly improved.

Purpose Of The Review: The purpose of this review is to outline current graft versus host disease (GvHD) prophylaxis, in the era of posttransplant cyclophosphamide (PTCY), in patients with malignant and nonmalignant hematologic disorders. The original combination of PTCY with a calcineurin inhibitor (CNI) and mycophenolate (MMF), reported from the Johns Hopkins University in Baltimore, was designed for patients receiving a graft from a donor mismatched at one haplotype, so called haploidentical donor (HAPLO). In the past decade, PTCY has been widely used in HAPLO transplants worldwide, confirming the amazing efficacy of PTCY in preventing GvHD in mismatched grafts.

Haploidentical-related donor (HID) hematopoietic stem cell transplantation (HSCT) has undergone significant advances in recent decades. Granulocyte colony-stimulating factor- and antithymocyte globulin-based protocols and post-transplantation cyclophosphamide-based regimens represent two of the current T-cell-replete protocols in HID HSCT. Recently, the optimization of several critical transplant techniques has further improved hematopoietic reconstitution, decreased the incidence of relapse and graft-versus-host disease after HID HSCT, and extended the application of HID HSCT to older patients and those with non-malignant hematologic disorders.
