Approach to Anemia
APPROACH TO ANEMIA Mahsa Mohebtash, MD Medstar Union Memorial Hospital Definition of Anemia • Reduced red blood mass • RBC measurements: RBC mass, Hgb, Hct or RBC count • Hgb, Hct and RBC count typically decrease in parallel except in severe microcytosis (like thalassemia) Normal Range of Hgb/Hct • NL range: many different values: • 2 SD below mean: < Hgb13.5 or Hct 41 in men and Hgb 12 or Hct of 36 in women • WHO: Hgb: <13 in men, <12 in women • Revised WHO/NCI: Hgb <14 in men, <12 in women • Scrpps-Kaiser based on race and age: based on 5th percentiles of the population in question • African-Americans: Hgb 0.5-1 lower than Caucasians Approach to Anemia • Setting: • Acute vs chronic • Isolated vs combined with leukopenia/thrombocytopenia • Pathophysiologic approach • Morphologic approach Reticulocytes • Reticulocytes life span: 3 days in bone marrow and 1 day in peripheral blood • Mature RBC life span: 110-120 days • 1% of RBCs are removed from circulation each day • Reticulocyte production index (RPI): Reticulocytes (percent) x (HCT ÷ 45) x (1 ÷ RMT): • <2 low Pathophysiologic approach • Decreased RBC production • Reduced effective production of red cells: low retic production index • Destruction of red cell precursors in marrow (ineffective erythropoiesis) • Increased RBC destruction • Blood loss Reduced RBC precursors • Low retic production index • Lack of nutrients (B12, Fe) • Bone marrow disorder => reduced RBC precursors (aplastic anemia, pure RBC aplasia, marrow infiltration) • Bone marrow suppression (drugs, chemotherapy, radiation) -

Despite the pandemic, 10 antibody therapeutics had been granted the immune-mediated disorders; first approval in the US or EU in 2020, as of November, and 2 more (tanezumab and margetuximab) may Sars-CoV-2 be granted approvals in December 2020.* In addition, prolgolimab and olokizumab had been granted first approvals in Russia and cetuximab saratolacan sodium was first approved in Japan. The number of approvals in 2021 may set a record, as marketing applications for 16 investigational antibody therapeutics are already undergoing regulatory review by either the FDA or the European Medicines Agency. -
Paroxysmal Cold Hemoglobinuria: a Case Report
CASE R EPO R T Paroxysmal cold hemoglobinuria: a case report S.C. Wise, S.H. Tinsley, and L.O. Cook A 15-month-old white male child was admitted to the pediatric hemolysis and possible pigment nephropathy and to rule out intensive care unit with symptoms of upper respiratory tract sepsis. He was started on oxygen by nasal cannula and given infection, increased somnolence, pallor, jaundice, fever, and intravenous fluids at half maintenance rates with bicarbonate decreased activity level. The purpose of this case study is to report the clinical findings associated with the patient’s administered to alkalinize the urine to prevent crystallization clinical symptoms and differential laboratory diagnosis. of myoglobin or hemoglobin. His urine output was monitored, Immunohematology 2012;28:118–23. and fluids were given judiciously to prevent congestive heart failure. He was also started empirically on ceftriaxone.

Complementopathies and Precision Medicine
Complementopathies and precision medicine Eleni Gavriilaki, Robert A. Brodsky J Clin Invest. 2020;130(5):2152-2163. https://doi.org/10.1172/JCI136094. Review The renaissance of complement diagnostics and therapeutics has introduced precision medicine into a widened field of complement-mediated diseases. In particular, complement-mediated diseases (or complementopathies) with ongoing or published clinical trials of complement inhibitors include paroxysmal nocturnal hemoglobinuria, cold agglutinin disease, hemolytic uremic syndrome, nephropathies, HELLP syndrome, transplant-associated thrombotic microangiopathy, antiphospholipid antibody syndrome, myasthenia gravis, and neuromyelitis optica. Recognizing that this field is rapidly expanding, we aim to provide a state-of-the-art review of (a) current understanding of complement biology for the clinician, (b) novel insights into complement with potential applicability to clinical practice, (c) complement in disease across various disciplines (hematology, nephrology, obstetrics, transplantation, rheumatology, and neurology), and (d) the potential future of precision medicine. Better understanding of complement diagnostics and therapeutics will not only facilitate physicians treating patients in clinical practice but also provide the basis for future research toward precision medicine in this field.

Autoimmune Hemolytic Anemia
Michalak et al. Immunity & Ageing (2020) 17:38 https://doi.org/10.1186/s12979-020-00208-7 REVIEW Open Access Autoimmune hemolytic anemia: current knowledge and perspectives Sylwia Sulimiera Michalak1* , Anna Olewicz-Gawlik2,3,4, Joanna Rupa-Matysek5, Edyta Wolny-Rokicka6, Elżbieta Nowakowska1 and Lidia Gil5 Abstract Autoimmune hemolytic anemia (AIHA) is an acquired, heterogeneous group of diseases which includes warm AIHA, cold agglutinin disease (CAD), mixed AIHA, paroxysmal cold hemoglobinuria and atypical AIHA. Currently CAD is defined as a chronic, clonal lymphoproliferative disorder, while the presence of cold agglutinins underlying other diseases is known as cold agglutinin syndrome. AIHA is mediated by autoantibodies directed against red blood cells (RBCs) causing premature erythrocyte destruction. The pathogenesis of AIHA is complex and still not fully understood. Recent studies indicate the involvement of T and B cell dysregulation, reduced CD4+ and CD25+ Tregs, increased clonal expansions of CD8 + T cells, imbalance of Th17/Tregs and Tfh/Tfr, and impaired lymphocyte apoptosis. Changes in some RBC membrane structures, under the influence of mechanical stimuli or oxidative stress, may promote autohemolysis. The clinical presentation and treatment of AIHA are influenced by many factors, including the type of AIHA, degree of hemolysis, underlying diseases, presence of concomitant comorbidities, bone marrow compensatory abilities and the presence of fibrosis and dyserthropoiesis. The main treatment for AIHA is based on the inhibition of autoantibody production by mono- or combination therapy using GKS and/or rituximab and, rarely, immunosuppressive drugs or immunomodulators. Reduction of erythrocyte destruction via splenectomy is currently the third line of treatment for warm AIHA. Supportive treatment including vitamin supplementation, recombinant erythropoietin, thrombosis prophylaxis and the prevention and treatment of infections is essential. -
A Case of COVID-19-Associated Autoimmune Hemolytic Anemia with Hyperferritinemia in an Immunocompetent Host

Internal Medicine, Northwell Health, New York, USA 4. Infectious Disease, Northwell Health, New York, USA 5. Internal Medicine, Mayo Hospital, Lahore, PAK Corresponding author: Syeda Sahra, [email protected] Abstract We report an interesting case of a middle-aged gentleman who presented with diabetic ketoacidosis (DKA) and tested polymerase chain reaction (PCR) positive for COVID-19 infection. His hospital stay was complicated by acute kidney injury, hematuria, and normocytic anemia. Initial chest x-ray demonstrated bibasilar opacities. D-dimer and C-reactive protein were elevated. During his hospital stay, his hemoglobin decreased from 13.4 g/dL to 9 g/dL, and further workup demonstrated ferritin of 49,081 ng/mL with lactate dehydrogenase of 1665 U/L. He was treated with prednisone and folic acid for autoimmune hemolytic anemia (AIHA). Ferritin was downtrended, and hemoglobin stabilized. As demonstrated by this case report and prior literature review, COVID-19 infection can be associated with AIHA. Categories: Infectious Disease, Hematology Keywords: covid-19, hyperferritinemia, high ferritin, autoimmune hemolytic anemia (aiha), hemolytic anemia Introduction Information regarding COVID-19 and associated coagulopathies is rapidly evolving and expanding. Thus far, many cases of autoimmune hemolytic anemia (AIHA) have been reported in patients with comorbidities such as thrombocytopenia, leukemia, lymphoma, various cancers, and autoimmune conditions [1]. -
