Functional Evaluation Of A Novel Rpl30 Mutation And Its Role In Diamond Blackfan Anemia (Dba), Alexandra Prosser, Alexandria Cockrell, Danny Miller, Chris Seidel, Tamara Potapova, John M. Perry, Midhat Farooqi, Erin M. Guest, Jennifer Gerton
Research Days
Background: Bone marrow failure is life-threatening and requires prompt, intensive treatment, which is dependent upon identification of genetic drivers. Although there has been investigation into associated genetic mutations, especially in Diamond Blackfan anemia (DBA), the relationship between genotype and phenotype remains unclear.DBA has been identified as a ribosomopathy, also known as a disease associated with defects in ribosome biogenesis. We identified a novel heterozygous variant (c.167+769C >T) in the noncoding region of RPL30 in a patient with clinical diagnosis of DBA. Clinical RNA sequencing (RNA-seq) suggests the variant generates a novel splice acceptor site resulting in truncated RPL30 transcripts. Elucidation …

Increasing Incentive Spirometry Use In Patients With Sickle Cell Disease: Longer Follow-Up Of Pdsa Cycle 1, Alexandra Prosser, Thomas Cochran
Research Days
Problem Statement/Question: Acute chest syndrome (ACS) is one of the leading causes of morbidity and mortality in patients with sickle cell disease. Patients are at higher risk for this complication during hospital admission due to limited mobility leading to decreased lung inflation. The National Heart, Lung, and Blood Institute (NHLBI) recommends providing ten breaths of incentive spirometry (IS) every two hours while awake for patients admitted to the hospital with sickle cell disease to help prevent development of acute chest syndrome. Without this intervention, patients are more likely to develop ACS requiring increased level of care, prolonged hospital stays, and …

Rapid Hepatomegaly From Ruxolitinib Discontinuation Syndrome, Ryan Jansen Van Rensburg, Shayna Hale, Anna Calara, Kulveer Dabb, Uday Dandamudi, Parth Desai
HCA Healthcare Journal of Medicine
Introduction
Ruxolitinib (RUX) is a Food and Drug Administration-approved Janus Kinase (JAK) inhibitor shown to be effective in improving hypercatabolic symptoms and splenomegaly in patients with myelofibrosis (MF). RUX therapy provides symptomatic benefits for MF patients but is often discontinued for various reasons including worsening cytopenias. Ruxolitinib Discontinuation Syndrome (RDS) involves an acute cytokine-storm rebound phenomenon that can manifest as an acute relapse of symptoms, worsening splenomegaly, respiratory distress, systemic inflammatory response syndrome, or disseminated intravascular coagulopathy.
Case Presentation
We present the case of a patient with JAK2-positive post-polycythemia vera MF, whose RUX therapy was discontinued due to an active …

Hematology/Oncology and Stem Cell Therapy
Background: Mutations in JAK2/STAT5 proliferation pathway genes are key in the diagnosis of myeloproliferative neoplasms (MPNBCR/ABLneg), with JAK2V617F being found in 50-97% of MPNBCR/ABLneg subtypes. Low JAK2V617F positivity at our facility suggested that our South African MPNBCR/ABLneg population may have a different mutational landscape. Objectives: We aimed to determine the JAK2/STAT5 mutation frequencies associated with our local MPNBCR/ABLneg population, thus determining the relevance of these molecular tests in this group. We also investigated the haematopathological relevance of each test request, to assess testing practises. Method: This study involved the retrospective audit of 886 patients for whom JAK2V617F mutation testing had …

Hematology/Oncology and Stem Cell Therapy
Acquired amegakaryocytic thrombocytopenic purpura (AATP) is a rare bone marrow disorder characterized by either a marked decrease or a complete absence of megakaryocytes with preservation of all other cell lines. More than 60 cases of AATP have been reported in literature thus far. Due to the rarity of this disease, no standard treatment guidelines have been established and therapy is based on a handful of case studies and expert opinion. Herein, we provide a comprehensive review on currently utilized therapeutic options for AATP.

Prevalence Of Iron Deficiency In Patients With Inherited Bleeding Disorders, Thomas Cochran, Brian Lee, Shannon Carpenter
Posters
Background: Synthesis of hemoglobin is one of several important roles iron plays in the human body. Approximately 50% of all anemia cases may be caused by iron deficiency which is frequently caused by chronic blood loss. Patients with bleeding disorders have greater propensity for blood loss and therefore may have a higher prevalence of iron deficiency when compared to the general population. However, few studies have assessed the prevalence of iron deficiency in children with inherited bleeding disorders. Objectives: This study aims to identify the prevalence of iron deficiency in children with an inherited bleeding disorder. Methods: A retrospective analysis …

Uberti, Abhinav Deol
Hematology/Oncology and Stem Cell Therapy
Mantle cell lymphoma is a rare subtype of non-Hodgkin’s lymphoma with poor prognosis and continue to be challenging to treat. The choice of first line induction regimen remains a topic of debate due paucity of clinical trials. We retrospectively evaluated 66 patients diagnosed with mantle cell lymphoma who achieved first complete response after induction chemotherapy followed by autologous stem cell transplant. Treatment groups were divided into lowintensity versus high-intensity regimens. Our data showed the intensity of induction regimen does not impact posttransplant outcomes of mantle cell lymphoma who underwent autologous stem cell transplant in first complete response.

Hematology/Oncology and Stem Cell Therapy
Primary central nervous system lymphoma (PCNSL) is a rare lymphoma that involves the central nervous system. The standard treatment involves chemotherapy with high-dose methotrexate. To the best of our knowledge, this is the first reported case of employing checkpoint inhibitor, nivolumab, alone to treat a patient with PCNSL who could not tolerate the induction therapy. In aggressive cases of PCNSL where chemotherapy may become futile, stand-alone checkpoint inhibitors should be considered as the front-line treatment protocol.
