    Abstract Acquired aplastic anemia and inherited bone marrow failure syndromes both present with pancytopenia and must be distinguished because they have differences in treatment decisions and continued monitoring requirements. Advances in the genetic interrogation of patient samples have led to identification of inherited germline diseases and appreciation that patients with inherited bone marrow failure disorders may be normal in appearance with few expected clinical clues. Somatic mutations in aplastic anemia may have prognostic value. Hematopoietic stem cells from inherited marrow failure diseases can correct the proliferative defect and may develop further somatic mutations that progress to myelodysplastic syndrome or acute myeloid leukemia.

    Abstract Diamond-Blackfan anemia (DBA) is a severe congenital hypoplastic anemia caused by mutation in a ribosomal protein gene. Major clinical issues concern the optimal management of patients resistant to steroids, the first-line therapy. Hematopoietic stem cell transplantation is indicated in young patients with an HLA-matched unaffected sibling donor, and recent results with matched unrelated donor transplants indicate that these patients also do well. When neither steroids nor a transplant is possible red cell transfusions are required, and iron loading is rapid in some DBA patients, so effective chelation is vital. Also discussed are novel treatments under investigation for DBA.

    Abstract Case: We report on a patient with heterozygous prothrombin G20210A mutation (PTM) and a history of venous thromboembolism (VTE) after knee arthroscopy, who was undergoing hip arthroscopy. This common mutation has an overall prevalence of 2.0% and results in a 280% to 420% likelihood of thrombosis compared to patients without the mutation.
    Conclusions: Hip arthroscopy is associated with a low risk of VTE with currently no guidelines for thromboprophylaxis. Patients should be managed in relation to their risk factors utilizing a collaborative, individualized approach. Treatment with short-term low-molecular-weight heparin resulted in no thromboembolism at 18-month follow-up for this patient with PTM.

    Abstract Diamond-Blackfan anaemia (DBA) is a congenital anaemia and broad developmental disease that develops soon after birth. The anaemia is due to failure of erythropoiesis, with normal platelet and myeloid lineages, and it can be managed with steroids, blood transfusions, or stem cell transplantation. Normal erythropoiesis after transplantation shows that the defect is intrinsic to an erythroid precursor. DBA is inherited in about 10-20% of cases, and genetic studies have identified mutations in a ribosomal protein gene, RPS19, in 25% of cases; there is evidence for involvement of at least two other genes. In yeast, RPS19 deletion leads to a block in ribosomal RNA biogenesis. The critical question is how mutations in RPS19 lead to the failure of proliferation and differentiation of erythroid progenitors. While this question has not yet been answered, understanding the biology of DBA may provide insight not only into the defect in erythropoisis, but also into the other developmental abnormalities that are present in about 40% of patients, and into the cancer predisposition that is inherent to DBA.

    Abstract Background: Diamond-Blackfan anemia (DBA) is an inherited bone marrow failure syndrome characterized by anemia, short stature, congenital anomalies, and cancer predisposition. Most cases are due to mutations in genes encoding ribosomal proteins (RP) leading to RP haploinsufficiency. Effective treatments for the anemia of DBA include chronic red cell transfusions, long-term corticosteroid therapy, or hematopoietic stem cell transplantation. In a small patient series and in animal models, there have been hematologic responses to L-leucine with amelioration of anemia. The study objectives of this clinical trial were to determine feasibility, safety, and efficacy of L-leucine in transfusion-dependent patients with DBA.
    Procedure: Patients ≥2 years of age received L-leucine 700 mg/m
    Results: This multicenter, phase I/II study enrolled 55 subjects; 43 were evaluable. There were 21 males; the median age at enrollment was 10.4 years (range, 2.5-46.1 years). No significant adverse events were attributable to L-leucine. Two subjects had a complete erythroid response and five had a partial response. Nine of 25, and 11 of 25, subjects experienced a positive weight and height percentile change, respectively, at the end of therapy.
    Conclusions: L-leucine is safe, resulted in an erythroid response in 16% of subjects with DBA, and led to an increase in weight and linear growth velocity in 36% and 44% of evaluable subjects, respectively. Further studies will be critical to understand the role of L-leucine in the management of patients with DBA.

    Abstract Shwachman-Diamond Syndrome (SDS) is a rare and clinically-heterogeneous bone marrow (BM) failure syndrome caused by mutations in the Shwachman-Bodian-Diamond Syndrome (SBDS) gene. Although SDS was described over 50 years ago, the molecular pathogenesis is poorly understood due, in part, to the rarity and heterogeneity of the affected hematopoietic progenitors. To address this, we used single cell RNA sequencing to profile scant hematopoietic stem and progenitor cells from SDS patients. We generated a single cell map of early lineage commitment and found that SDS hematopoiesis was left-shifted with selective loss of granulocyte-monocyte progenitors. Transcriptional targets of transforming growth factor-beta (TGFβ) were dysregulated in SDS hematopoietic stem cells and multipotent progenitors, but not in lineage-committed progenitors. TGFβ inhibitors (AVID200 and SD208) increased hematopoietic colony formation of SDS patient BM. Finally, TGFβ3 and other TGFβ pathway members were elevated in SDS patient blood plasma. These data establish the TGFβ pathway as a novel candidate biomarker and therapeutic target in SDS and translate insights from single cell biology into a potential therapy.
