The Diagnosis of Paroxysmal Nocturnal Hemoglobinuria: Role of Flow Cytometry

CD59: a Long-Known Complement Inhibitor Has Advanced to a Blood Group System
B LOOD G ROUP R EVIEW CD59: A long-known complement inhibitor has advanced to a blood group system C. Weinstock, M. Anliker, and I. von Zabern The blood group system number 35 is based on CD59, a 20-kDa by Zalman et al.1 from the group of H.J. Muller-Eberhard in La membrane glycoprotein present on a large number of different Jolla, California, and in 1988 by Schönermark et al. from the cells, including erythrocytes. The major function of CD59 is to group of G.M. Hänsch in Heidelberg (Germany).2 This inhibitor protect cells from complement attack. CD59 binds to complement components C8 and C9 and prevents the polymerization of C9, was published under the designations “HRF (homologous which is required for the formation of the membrane attack restriction factor)” and “C8bp (C8 binding protein),” complex (MAC). Other functions of CD59 in cellular immunity respectively, to describe its properties.1,2 “C8bp” indicates the are less well defined. CD59 is inserted into the membrane by a glycosylphosphatidylinositol (GPI) anchor. A defect of this anchor binding capacity for C8. The name “HRF” points to a species causes lack of this protein from the cell membrane, which leads to incompatibility of this “factor” that provides protection from an enhanced sensitivity towards complement attack. Patients with complement attack more effectively in a homologous (e.g., paroxysmal nocturnal hemoglobinuria (PNH) harbor a varying human erythrocytes as a target of human complement) than in percentage of red blood cell clones with a defect in GPI-anchored proteins, including CD59. The most characteristic symptoms of a heterologous system (e.g., human erythrocytes as a target of this disease are episodes of hemolysis and thromboses. -

Introduction to the Rhesus Blood Group Justin R. Rhees, M.S., MLS(ASCP)CM, SBBCM University of Utah Department of Pathology Medical Laboratory Science Program Objectives 1. Describe the major Rhesus (Rh) blood group antigens in terms of biochemical structure and inheritance. 2. Describe the characteristics of Rh antibodies. 3. Translate the five major Rh antigens, genotypes, and haplotypes from Fisher-Race to Wiener nomenclature. 4. State the purpose of Fisher-Race, Wiener, Rosenfield, and ISBT nomenclatures. Background . How did this blood group get its name? . 1937 Mrs. Seno; Bellevue hospital . Unknown antibody, unrelated to ABO . Philip Levine tested her serum against 54 ABO-compatible blood samples: only 13 were compatible. Rhesus (Rh) blood group 1930s several cases of Hemolytic of the Fetus and Newborn (HDFN) published. Hemolytic transfusion reactions (HTR) were observed in ABO- compatible transfusions. In search of more blood groups, Landsteiner and Wiener immunized rabbits with the Rhesus macaque blood of the Rhesus monkeys. Rhesus (Rh) blood group 1940 Landsteiner and Wiener reported an antibody that reacted with about 85% of human red cell samples. It was supposed that anti-Rh was the specificity causing the “intragroup” incompatibilities observed. 1941 Levine found in over 90% of erythroblastosis fetalis cases, the mother was Rh-negative and the father was Rh-positive. Rhesus macaque Rhesus (Rh) blood group Human anti-Rh and animal anti- Rh are not the same. However, “Rh” was embedded into blood group antigen terminology. The -

Apheresis Red Cell Exchange/Transfusions
APHERESIS RED CELL EXCHANGE/TRANSFUSIONS In a patient treated in Manchester, parasitemia was virtually eliminated over eight hours by a 3.5 liter exchange blood transfusion (Plasmodium Falciparum Hyperparasitemia: Use of Exchange Transfusion in Seven Patients and a Review of the Literature). Several cases of severe babesiosis refractory to appropriate antibiotic therapy have been reported to respond promptly and dramatically to red blood cell (RBC) exchange transfusion. Asplenic patients, however, generally have a more severe course of illness, with hemolytic anemia, acute renal failure, disseminated intravascular coagulation, and pulmonary edema. Primary therapy is with antibiotics including clindamycin and quinine, with RBC exchange transfusion reported to be effective in severe cases. The RBC exchange transfusions succeeded in reducing significantly the level of parasitemia, dramatically improving the condition of an extremely ill patient. Our report adds to the small but growing literature on severe Babesia infection in humans, and provides further evidence to support the use of RBC exchange transfusion to treat severe babesiosis. Its single great advantage over antibiotic therapy is its rapid therapeutic effectiveness (Treatment of Babesiosis by Red Blood Cell Exchange in an HIV-Positive Splenectomized Patient). There was rapid clinical improvement after the whole-blood exchange transfusion. In cases of severe babesiosis, prompt institution of whole-blood exchange transfusion, in combination with appropriate antimicrobial therapy, can be life-saving. In patients with progressive babesiosis, early intervention with exchange transfusion, along with appropriate antimicrobial therapy, should be considered to speed clinical recovery. (Fulminant babesiosis treated with clindamycin, quinine, and whole-blood exchange transfusion. However, asplenic patients may have a much more serious clinical course. -

Introduction Iron is an essential nutrient that plays a central role in many metabolic processes. Aerobic metabolism is critically dependent on maintaining normal concentrations of several iron-containing proteins that mediate oxygen transport, storage and utili- zation, particularly when the tissue demand for oxygen is increased by physical ac- tivity. Pioneering research over the last 50 years, much of it stemming from concepts developed and validated experimentally by Dr Clement Finch and his coworkers, led to the recognition that a negative iron balance resulting from an iron intake insuf- ficient to match losses from the body despite compensatory changes in the rate of absorption and, to a more limited extent, excretion could be divided into three stages based on the severity of the potential effect on physiological functions. The evalua- tion of functional impairment was related entirely to erythropoiesis for two reasons: the effects of changes in iron status on blood elements are readily evaluated, while the effect on the enzymes in other tissues necessitates obtaining biopsy samples. -
