  • Hemolytic Disease of the Newborn
    Intensive Care Nursery House Staff Manual Hemolytic Disease of the Newborn INTRODUCTION and DEFINITION: Hemolytic Disease of the Newborn (HDN), also known as erythroblastosis fetalis, isoimmunization, or blood group incompatibility, occurs when fetal red blood cells (RBCs), which possess an antigen that the mother lacks, cross the placenta into the maternal circulation, where they stimulate antibody production. The antibodies return to the fetal circulation and result in RBC destruction. DIFFERENTIAL DIAGNOSIS of hemolytic anemia in a newborn infant: -Isoimmunization -RBC enzyme disorders (e.g., G6PD, pyruvate kinase deficiency) -Hemoglobin synthesis disorders (e.g., alpha-thalassemias) -RBC membrane abnormalities (e.g., hereditary spherocytosis, elliptocytosis) -Hemangiomas (Kasabach Merritt syndrome) -Acquired conditions, such as sepsis, infections with TORCH or Parvovirus B19 (anemia due to RBC aplasia) and hemolysis secondary to drugs. ISOIMMUNIZATION A. Rh disease (Rh = Rhesus factor) (1) Genetics: Rh positive (+) denotes presence of D antigen. The number of antigenic sites on RBCs varies with genotype. Prevalence of genotype varies with the population. Rh negative (d/d) individuals comprise 15% of Caucasians, 5.5% of African Americans, and <1% of Asians. A sensitized Rh negative mother produces anti-Rh IgG antibodies that cross the placenta. Risk factors for antibody production include 2nd (or later) pregnancies*, maternal toxemia, paternal zygosity (D/D rather than D/d), feto-maternal compatibility in ABO system and antigen load. (2) Clinical presentation of HDN varies from mild jaundice and anemia to hydrops fetalis (with ascites, pleural and pericardial effusions). Because the placenta clears bilirubin, the chief risk to the fetus is anemia. Extramedullary hematopoiesis (due to anemia) results in hepatosplenomegaly.

  • A Newly Recognized Blood Group in Domestic Shorthair Cats: the Mik Red Cell Antigen
    J Vet Intern Med 2007;21:287–292 A Newly Recognized Blood Group in Domestic Shorthair Cats: The Mik Red Cell Antigen Nicole M. Weinstein, Marie-Claude Blais, Kimberly Harris, Donna A. Oakley, Lillian R. Aronson, and Urs Giger Background: Naturally occurring alloantibodies produced against A and B red cell antigens in cats can cause acute hemolytic transfusion reactions. Blood incompatibilities, unrelated to the AB blood group system, have also been suspected after blood transfusions through routine crossmatch testing or as a result of hemolytic transfusion reactions. Hypothesis: Incompatible crossmatch results among AB compatible cats signify the presence of a naturally occurring alloantibody against a newly identified blood antigen in a group of previously never transfused blood donor cats. The associated alloantibody is clinically important based upon a hemolytic transfusion reaction after inadvertent transfusion of red cells expressing this red cell antigen in a feline renal transplant recipient that lacks this red cell antigen. Methods: Blood donor and nonblood donor cats were evaluated for the presence of auto- and alloantibodies using direct antiglobulin and crossmatch tests, respectively, and were blood typed for AB blood group status. Both standard tube and novel gel column techniques were used. Results: Plasma from 3 of 65 cats and 1 feline renal transplant recipient caused incompatible crossmatch test results with AB compatible erythrocytes indicating these cats formed an alloantibody against a red cell antigen they lack, termed Mik. The 3 donors and the renal transplant recipient were crossmatch-compatible with one another. Tube and gel column crossmatch test results were similar. Conclusions and Clinical Importance: The absence of this novel Mik red cell antigen can be associated with naturally occurring anti-Mik alloantibodies and can elicit an acute hemolytic transfusion reaction after an AB-matched blood transfusion.

REF 813 420 100 VOL 48 cards per box............ REF 813 421 100 VOL 288cards per box........... REF 813 422 100 INTENDED USE The IH-Card AHG Anti-IgG is intended for the detection of antibodies on human red blood cells using the Direct and Indirect Antiglobulin Tests. SUMMARY Moreschi first described the use of Anti-Human Globulin in 1908.1 Coombs rediscovered the test in 1945.2,3 By injecting rabbits with human IgG, they were able to produce a protein (Anti-IgG) that reacted with ˝incomplete˝ antibodies (IgG). Most ˝incomplete˝ antibodies (IgG) fail to agglutinate red blood cells suspended in saline.4 Most clinically significant antibodies in red blood cell serology are of the IgG class and can only be detected by the use of Anti-IgG. The IH-Card AHG Anti-IgG is suitable for the Direct and Indirect Antiglobulin Tests. The Direct Antiglobulin Test allows the detection of in vivo sensitization of human red blood cells with immunoglobulins. The Indirect Antiglobulin Tests allows the detection of in vitro sensitization of human red blood cells with clinically significant antibodies. The Indirect Antiglobulin Test may be used for antibody detection, identification, IAT crossmatching , and D variant testing. An optional autocontrol may help to distinguish autoantibodies and alloantibodies.

Department of Pediatrics, Children’s Medical Center, Pediatrics Center of Excellence, Tehran University of Medical Sciences, Tehran, IR Iran 2. Department of Pathology, Tehran University of Medical Sciences, Tehran, IR Iran Received: Jan 30, 2009; Final Revision: Apr 25, 2009; Accepted: May 22, 2009 Abstract Background: Giant cell hepatitis (GCH) is a histological finding in infants with neonatal cholestasis and rarely can be seen after this period. Autoimmune hemolytic anemia (AIHA) which is characterized by massive and acute red blood cell destruction due to antibody production, responds favorably to corticosteroid therapy. The combination of GCH and AIHA is a rare distinct entity that carries poor response to immunosuppressive therapy and often progresses to fatal liver disease. Case Presentation: A 13‐month‐old boy was referred to us with anemia and icterus. Investigations confirmed the diagnosis of GCH which was associated with AIHA. Treatment with steroids and azathioprin failed. We changed to cyclosporine. The anemia improved by steroid and IVIG at the beginning, but few months later anemia relapsed. Finally he recovered with rituximab and now he is 6 years old in suitable condition. Conclusion: The association of AIHA with GCH is an uncommon condition that can be life threatening. Most patients initially respond to immunosuppressive agents, but usually recur and have an aggressive course. In this case liver disease responded to steroid and immunosuppressive therapy, but the AIHA was refractory to immunosuppressive therapy.

Plasmapheresis in a child with cold antibody autoim- mune hemolytic anemia: Case report. Turk Pediatri Ars 2017; 52: 169-72. Abstract Autoimmune hemolytic anemia is a picture of hemolysis which is caused by autoantibodies against red blood cell surface antigens. It is classified as primary, secondary or warm and cold autoimmune hemolytic anemia according to the temperature at which antibodies react. It is usually an acute and self-limiting condition. Here, we present a three-year-old male patient who presented with malaise, paleness, and dark-colored urine. His hemoglobin level was 5.8 g/dL, and increased indirect bilirubin and lactate dehydrogenase levels and decreased hap- toglobulin and reticulocyte levels were noted. A direct Coombs test was positive using anti-C3. Four erythrocyte suspension transfusions were given because the anemia was life-threatening. High-dose steroids (30 mg/kg/ day, methylprednisolone) and intravenous immunoglobulin (1 g/kg/day, two days) treatments were unresponsive. Plasmapheresis was performed and no further transfusions were needed after plasma- pheresis. Plasmapheresis treatment can be effective in children with cold type autoimmune hemolytic anemia. Key words: Autoimmune hemolytic anemia, cold antibody, plasmapheresis Introduction warm-antibody hemolytic anemia.
