27. Clinical Indications for Cryoprecipitate And
27. CLINICAL INDICATIONS FOR CRYOPRECIPITATE AND FIBRINOGEN CONCENTRATE Cryoprecipitate is indicated in the treatment of fibrinogen deficiency or dysfibrinogenaemia.1 Fibrinogen concentrate is licenced for the treatment of acute bleeding episodes in patients with congenital fibrinogen deficiency, including afibrinogenaemia and hypofibrinogenaemia,2 and is currently funded under the National Blood Agreement. Key messages y Fibrinogen is an essential component of the coagulation system, due to its role in initial platelet aggregation and formation of a stable fibrin clot.3 y The decision to transfuse cryoprecipitate or fibrinogen concentrate to an individual patient should take into account the relative risks and benefits.3 y The routine use of cryoprecipitate or fibrinogen concentrate is not advised in medical or critically ill patients.2,4 y Cryoprecipitate or fibrinogen concentrate may be indicated in critical bleeding if fibrinogen levels are not maintained using FFP. In the setting of major obstetric haemorrhage, early administration of cryoprecipitate or fibrinogen concentrate may be necessary.3 Clinical implications y The routine use of cryoprecipitate or fibrinogen concentrate in medical or critically ill patients with coagulopathy is not advised. The underlying causes of coagulopathy should be identified; where transfusion is considered necessary, the risks and benefits should be considered for each patient. Specialist opinion is advised for the management of disseminated intravascular coagulopathy (MED-PP18, CC-PP7).2,4 y Cryoprecipitate or fibrinogen concentrate may be indicated in critical bleeding if fibrinogen levels are not maintained using FFP. In patients with critical bleeding requiring massive transfusion, suggested doses of blood components is 3-4g (CBMT-PP10)3 in adults or as per the local Massive Transfusion Protocol. -
Transfusion Service Introduction Blood/Blood Products Requests and Turnaround Time Expectations
Transfusion Service Introduction All blood products and blood components are supplied to UnityPoint Health-Meriter Hospital by the American Red Cross Blood Services. Pathology consultation is available regarding blood and/or components and dosages. ABO and Rho(D)—specific type is used whenever possible for leuko-poor packed cell transfusions. ABO-compatible blood is used for all plasma and platelet components whenever possible. For any orders involving HLA-matched components, the patient must have been HLA typed (sent to the American Red Cross) a minimum of 48 hours prior to intended infusion of the component. HLA typing is only required once. Blood components that are thawed, pooled, washed, volume-reduced, or deglycerolized for a patient will be charged to the patient even if not transfused. The charge is done because these components may not be suitable for another patient. Examples include: Autologous or directed donations Pooled cryoprecipitate 4-hour expiration Thawed fresh frozen plasma 24-hour expiration Thawed cryoprecipitate 6-hour expiration Deglycerolized red cells 24-hour expiration Washed red cells 24-hour expiration All blood components must be completely infused within 4 hours of release from UnityPoint Health-Meriter Laboratories Blood Bank, or be infused within the expiration time. Refer to UnityPoint Health -Meriter’s Blood and Blood Products Transfusion Policy #123 for additional information located on MyMeriter. Blood/Blood Products Requests and Turnaround Time Expectations Requests from UnityPoint Health-Meriter Hospital are entered in the hospital computer system and print in the UnityPoint Health- Meriter Laboratories Blood Bank. For the comfort of the patient, it is important to coordinate collection for other tests with Blood Bank specimens. -

(ACIP) General Best Guidance for Immunization
8. Altered Immunocompetence Updates This section incorporates general content from the Infectious Diseases Society of America policy statement, 2013 IDSA Clinical Practice Guideline for Vaccination of the Immunocompromised Host (1), to which CDC provided input in November 2011. The evidence supporting this guidance is based on expert opinion and arrived at by consensus. General Principles Altered immunocompetence, a term often used synonymously with immunosuppression, immunodeficiency, and immunocompromise, can be classified as primary or secondary. Primary immunodeficiencies generally are inherited and include conditions defined by an inherent absence or quantitative deficiency of cellular, humoral, or both components that provide immunity. Examples include congenital immunodeficiency diseases such as X- linked agammaglobulinemia, SCID, and chronic granulomatous disease. Secondary immunodeficiency is acquired and is defined by loss or qualitative deficiency in cellular or humoral immune components that occurs as a result of a disease process or its therapy. Examples of secondary immunodeficiency include HIV infection, hematopoietic malignancies, treatment with radiation, and treatment with immunosuppressive drugs. The degree to which immunosuppressive drugs cause clinically significant immunodeficiency generally is dose related and varies by drug. Primary and secondary immunodeficiencies might include a combination of deficits in both cellular and humoral immunity. Certain conditions like asplenia and chronic renal disease also can cause altered immunocompetence. Determination of altered immunocompetence is important to the vaccine provider because incidence or severity of some vaccine-preventable diseases is higher in persons with altered immunocompetence; therefore, certain vaccines (e.g., inactivated influenza vaccine, pneumococcal vaccines) are recommended specifically for persons with these diseases (2,3). Administration of live vaccines might need to be deferred until immune function has improved. -
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. -

Classically, the eosinophil was considered to fulfill a protective role against parasitic infections, primarily large multicellular helminths. Although eosinophils are predominantly associated with parasite infections, evidence of a role for eosinophils in mediating immunity against bacterial, viral, and fungal infections has been recently reported. Among the mechanisms by which eosinophils are proposed to exert their protective effects is the production of DNA-based extracellular traps (ETs).

Policy and Procedure
Policy and Procedure Title: Exchange Transfusion for Sickle Cell Division: Medical Management Disease Department: Utilization Management Approval Date: 2/9/18 LOB: Medicaid, Medicare, HIV SNP, CHP, MetroPlus Gold, Goldcare I&II, Market Plus, Essential, HARP Effective Date: 2/9/18 Policy Number: UM-MP224 Review Date: 1/18/19 Cross Reference Number: Retired Date: Page 1 of 7 1. POLICY: Exchange Transfusion for Sickle Cell Disease 2. RESPONSIBLE PARTIES: Medical Management Administration, Utilization Management, Integrated Care Management, Claims Department, Provider Contracting 3. DEFINITIONS • Sickle cell disease – Sickle cell disease (SCD) refers to a group of inherited disorders characterized by sickled red blood cells (RBCs), caused either by homozygosity for the sickle hemoglobin mutation (HbSS; sickle cell anemia) or by compound heterozygosity for the sickle mutation and a second beta globin gene mutation (e.g., sickle-beta thalassemia, HbSC disease). In either HbSS or compound heterozygotes, the majority of Hgb is sickle Hgb (HgbS; i.e., >50 percent). • Transfusion – Simple transfusion refers to transfusion of RBCs without removal of the patient's blood. • Exchange Transfusion – Exchange transfusion involves transfusion of RBCs together with removal of the patient's blood. Exchange transfusion can be performed manually or via apheresis (also called cytapheresis or hemapheresis) using an extracorporeal continuous flow device. 4. PROCEDURE: A. Exchange transfusion for sickle cell disease will be covered as an ambulatory surgery procedure when all the following criteria are met: i) The member has documented SCD. ii) The exchange transfusion is a pre-scheduled procedure. iii) The purpose of the exchange transfusion is to prevent stroke, acute chest syndrome, or recurrent painful episodes. -
Sickle Cell Disease: Chronic Blood Transfusions
Sickle Cell Disease: Chronic Blood Transfusions There may be times when sickle cell patients require a blood transfusion. Such situations include preparing for surgery, during pregnancy, or during a severe complication such as an aplastic crisis, splenic sequestration or acute chest syndrome. In these cases, transfusion is a one-time intervention used to reduce the severity of the complication you are experiencing. However, if you have had a stroke, or an MRI or TCD shows that you are at high risk for having a stroke, your hematologist may recommend you begin chronic blood transfusions. What Does a Blood Transfusion Do? What are The Risks? Chronic (monthly) blood transfusions have been proven to Blood transfusions are not without risks. One risk is drastically reduce a sickle cell patient’s risk of stroke. They alloimmunization, a process in which the patient receiving have also been shown to reduce the frequency, severity blood transfusions creates antibodies to certain types of and duration of other sickle cell complications. Sickle cell blood. As a result he/she may have a reaction to the blood patients usually have a hemoglobin S level of about 80- that was transfused. Alloimmunization makes it more 90%. This means 80-90% of the circulating red blood cells difficult to find blood that is a good match for the patient. are cells that can sickle and cause complications. The goal In order to prevent alloimmunization, some centers of chronic blood transfusion therapy is to bring that routinely perform RBC phenotyping (special testing for percentage down below 30%. This will mean fewer sickle antibodies) on sickle cell disease patients so that they may cells circulating in the body, and a lower risk of give blood that is a better match for the patient.
