  3. [해외논문]   Targeting HbS Polymerization   SCI SCIE

    Ferrone, Frank A.
    Seminars in hematology v.55 no.2 ,pp. 53 - 59 , 2018 , 0037-1963 ,

    초록

    Abstract The mutation of β6 from glu to val in hemoglobin is responsible for the polymer formation that leads to vaso-occlusion, and a range of severe consequences in sickle cell disease. The treatment of the disease can be addressed in many ways, but the prevention of polymer formation is one of the most fundamental approaches one can take. Such prevention includes affecting the polymer structure, or dilution of the fraction of polymerizable hemoglobin. The latter approach includes (1) induction of HbF, which does not itself, nor in hybrid form, join sickle polymers, or (2) restricting the allosteric change in hemoglobin that occurs in oxygen delivery, and which is required for polymer formation. These approaches will be critically reviewed, as well as the most recent developments that show the benefits of simply swelling the volume of the red cell.

  4. [해외논문]   Fetal Hemoglobin Induction by Epigenetic Drugs   SCI SCIE

    초록

    Abstract Fetal hemoglobin (HbF) inhibits the root cause of sickle pathophysiology, sickle hemoglobin polymerization. Individuals who naturally express high levels of HbF beyond infancy thus receive some protection from sickle complications. To mimic this natural genetic experiment using drugs, one guiding observation was that HbF is increased during recovery of bone marrow from extreme stress. This led to evaluation and approval of the cytotoxic (cell killing) drug hydroxyurea to treat sickle cell disease. Cytotoxic approaches are limited in potency and sustainability, however, since they require hematopoietic reserves sufficient to repeatedly mount recoveries from stress that destroys their counterparts, and such reserves are finite. HbF induction even by stress ultimately involves chromatin remodeling of the gene for HbF ( HBG ), therefore, a logical alternative approach is to directly inhibit epigenetic enzymes that repress HBG —implicated enzymes include DNA methyltransferase 1, histone deacetylases, lysine demethylase 1, protein arginine methyltransferase 5, euchromatic histone lysine methyltransferase 2 and chromodomain helicase DNA-binding protein 4. Clinical proof-of-principle that this alternative, noncytotoxic approach can generate substantial HbF and total hemoglobin increases has already been generated. Thus, with continued careful attention to fundamental biological and pharmacologic considerations (reviewed herein), there is potential that rational, molecular-targeted, safe and highly potent disease-modifying therapy can be realized for patients with sickle cell disease, with the accessibility and cost-effective properties needed for world-wide effect.

    초록

    Abstract Sickle cell disease is an inherited hemoglobinopathy characterized by hemolytic anemia, frequent painful episodes, poor quality of life, end organ damage and a shortened lifespan. Although the seminal event is the polymerization of the abnormal hemoglobin, the downstream pathophysiology of vaso-occlusion results from heterotypic interactions between the altered, adhesive sickle cell RBCs, neutrophils, endothelium, and platelets. Ischemia reperfusion injury, hemolysis and oxidant damage all contribute to heightened inflammation and activation of the hemostatic system. These downstream targets are the focus of emerging treatments with considerable potential to ameliorate disease manifestations. This review summarizes the progress on development of these agents.

  6. [해외논문]   Genetic therapies for sickle cell disease   SCI SCIE

    초록

    Abstract After decades with few novel therapeutic options for sickle cell disease (SCD), autologous hematopoietic stem cell (HSC) based genetic therapies including lentiviral gene therapy (GT), and genome editing (GE) now appear imminent. Lentiviral GT has advanced considerably in the past decade with promising clinical trial results in multiple disorders. For β-hemoglobinopathies, GT strategies of gene addition and fetal hemoglobin induction through BCL11A regulation are both being evaluated in open clinical trials. GE techniques offer the possibility of a nonviral curative approach, either through sickle hemoglobin mutation repair or fetal hemoglobin elevation. Although GE currently remains at the preclinical stage, multiple clinical trials will likely open soon. In addition to reviewing current strategies for GT and GE, this review highlights important next steps toward optimization of these therapies. All autologous cell-based genetic therapies rely on safely obtaining an adequate yield of autologous HSCs for genetic modification and transplantation. HSC collection is uniquely challenging in SCD. Peripheral mobilization with plerixafor has recently emerged as a promising approach. The acute and long-term toxicities associated with myeloablative conditioning are risks that may not be acceptable to a significant number of SCD patients, highlighting the need for novel conditioning regimens. Finally, increasing availability of autologous genetic therapies will require comprehensive and collaborative discussions regarding cost and access for SCD patients, at individual centers and worldwide.

    Abstract Sickle cell disease (SCD) chronically damages multiple organs over the lifetime of affected individuals. Allogeneic hematopoietic cell transplantation (allo-HCT) is the most studied curative intervention. Fully matched related marrow, peripheral blood derived, or cord blood HCT have the best transplant outcome for symptomatic patients with SCD. For patients with asymptomatic or milder disease who have this donor option available, risks and benefits of HCT should be discussed among the patient, family, treating hematologist, and transplant physician, and decision to proceed to HCT should be individualized. Myeloablative conditioning with busulfan, cyclophosphamide, and ATG has been a commonly employed regimen for children and young adults. Recently, low intensity conditioning with low dose total body irradiation and alemtuzumab is emerging as an efficacious and safe regimen for adults, young adults, and possibly children. Mixed donor chimerism (minimum ≥20% myeloid cells), from myeloablative or nonmyeloablative conditioning regimen, produces robust normal donor erythropoiesis and is sufficient to provide a clinical cure. The proportion of patients remaining on immunosuppression beyond 2 years post-HCT is likely

    초록

    Abstract Many patients with sickle cell disease experience severe morbidity and early mortality. The only curative option remains hematopoietic stem cell transplantation. Although HLA-matched sibling transplantation has been very successful for adults and children, the vast majority of patients with sickle cell disease do not have an HLA-matched sibling. Alternative donor options include haploidentical, unrelated umbilical cord blood, and matched unrelated donor transplantation. This report summarizes major alternative donor transplantation studies reported to date and ongoing and upcoming clinical trials. We conclude that when there is no HLA-match, all these approaches should be systematically considered before ruling out the option of hematopoietic stem cell transplantation.

    초록

    Abstract The vast majority of the world’s population of children and adults with sickle cell disease (SCD) are born in low-resource settings, particularly in sub-Saharan Africa, the Caribbean, the Middle East, and India. As a result numerous well-established, cost-effective, and evidence-based strategies for managing SCD such as newborn screening, early education, vaccinations, screening for stroke prevention, and treatments with safe transfusions and hydroxyurea are often unavailable, leading to substantial morbidity and increased mortality. Collaborations between high-income countries and these low-resource settings (North-South partnerships) have been advocated, with the goal of improving clinical care. Based on directives promulgated by the World Health Organization, we have developed a strategy of developing prospective research programs that focus on training, capacity building, and local data collection. This strategy involves consideration of important guiding principles, full partnerships, proper planning, and financial issues before program launch, after which rigorous program management is required for full effect and long-term sustainability. Ultimately these collaborative research programs should help create national guidelines and lead to improved clinical care for all children and adults with SCD.
