Abstract: Plasma hemopexin (HPX) is the key antioxidant protein of the endogenous clearance pathway that limits the deleterious effects of heme released from hemoglobin and myoglobin (the term “heme” is used in this article to denote both the ferrous and ferric forms). During intra-vascular hemolysis, heme partitioning to protein and lipid increases as the plasma concentration of HPX declines. Therefore, the development of HPX as a replacement therapy during high heme stress could be a relevant intervention for hemolytic disorders. A logical approach to enhance HPX yield involves recombinant production strategies from human cell lines. The present study focuses on a biophysical assessment of heme binding to recombinant human HPX (rhHPX) produced in the Expi293FTM (HEK293) cell system. -
Section 8: Hematology CHAPTER 47: ANEMIA
Section 8: Hematology CHAPTER 47: ANEMIA Q.1. A 56-year-old man presents with symptoms of severe dyspnea on exertion and fatigue. His laboratory values are as follows: Hemoglobin 6.0 g/dL (normal: 12–15 g/dL) Hematocrit 18% (normal: 36%–46%) RBC count 2 million/L (normal: 4–5.2 million/L) Reticulocyte count 3% (normal: 0.5%–1.5%) Which of the following caused this man’s anemia? A. Decreased red cell production B. Increased red cell destruction C. Acute blood loss (hemorrhage) D. There is insufficient information to make a determination Answer: A. This man presents with anemia and an elevated reticulocyte count which seems to suggest a hemolytic process. His reticulocyte count, however, has not been corrected for the degree of anemia he displays. This can be done by calculating his corrected reticulocyte count ([3% × (18%/45%)] = 1.2%), which is less than 2 and thus suggestive of a hypoproliferative process (decreased red cell production). Q.2. A 25-year-old man with pancytopenia undergoes bone marrow aspiration and biopsy, which reveals profound hypocellularity and virtual absence of hematopoietic cells. Cytogenetic analysis of the bone marrow does not reveal any abnormalities. Despite red blood cell and platelet transfusions, his pancytopenia worsens. Histocompatibility testing of his only sister fails to reveal a match. What would be the most appropriate course of therapy? A. Antithymocyte globulin, cyclosporine, and prednisone B. Prednisone alone C. Supportive therapy with chronic blood and platelet transfusions only D. Methotrexate and prednisone E. Bone marrow transplant Answer: A. Although supportive care with transfusions is necessary for treating this patient with aplastic anemia, most cases are not self-limited. -
Method Development and Validation of Vitamin D2 and Vitamin D3 Using Mass Spectrometry
Method Development and Validation of Vitamin D2 and Vitamin D3 Using Mass Spectrometry Devon Victoria Riley A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science University of Washington 2016 Committee: Andrew Hoofnagle Geoffrey Baird Dina Greene Program Authorized to Offer Degree: Laboratory Medicine ©Copyright 2016 Devon V. Riley ii University of Washington Abstract Method Development and Validation of Vitamin D2 and Vitamin D3 Using Mass Spectrometry Devon V. Riley Chair of the Supervisory Committee: Associate Professor Andrew Hoofnagle, MD, PhD Vitamin D has long been known to maintain bone health by regulating calcium and phosphorous homeostasis. In recent years, scientists have discovered additional physiological roles for vitamin D. The complex interaction between the active vitamin D hormone and its metabolic precursors continues to be a rich area of research. Fundamental to this research is the availability of accurate and precise assays. Few published assays for vitamins D2 and D3 have contained sufficient details on method validation or performance characteristics. The liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay developed for this thesis has undergone a rigorous validation and proven to yield a sensitive and specific method that exceeds the capabilities of all previously published methods. Developing and validating a novel assay is often complicated by the lack of established acceptability standards. This thesis explores this challenge, specifically for establishing meaningful interpretations and qualification standards of the lower limit of the measuring interval. Altogether, future research focused on vitamins D2, D3 and the Vitamin D pathway can benefit from this robust LC-MS/MS assay and the associated quality parameters outlined in this thesis. -
Severe Metabolic Acidosis in a Patient with an Extreme Hyperglycaemic Hyperosmolar State: How to Manage? Marloes B
Clinical Case Reports and Reviews Case Study ISSN: 2059-0393 Severe metabolic acidosis in a patient with an extreme hyperglycaemic hyperosmolar state: how to manage? Marloes B. Haak, Susanne van Santen and Johannes G. van der Hoeven* Department of Intensive Care Medicine, Radboud University Medical Center, Nijmegen, the Netherlands Abstract Hyperglycaemic hyperosmolar state (HHS) and diabetic ketoacidosis (DKA) are often accompanied by severe metabolic and electrolyte disorders. Analysis and treatment of these disorders can be challenging for clinicians. In this paper, we aimed to discuss the most important steps and pitfalls in analyzing and treating a case with extreme metabolic disarrangements as a consequence of an HHS. Electrolyte disturbances due to fluid shifts and water deficits may result in potentially dangerous hypernatriema and hyperosmolality. In addition, acid-base disorders often co-occur and several approaches have been advocated to assess the acid-base disorder by integration of the principles of mass balance and electroneutrality. Based on the case vignette, four explanatory methods are discussed: the traditional bicarbonate-centered method of Henderson-Hasselbalch, the strong ion model of Stewart, and its modifications ‘Stewart at the bedside’ by Magder and the simplified Fencl-Stewart approach. The four methods were compared and tested for their bedside usefulness. All approaches gave good insight in the metabolic disarrangements of the presented case. However, we found the traditional method of Henderson-Hasselbalch and ‘Stewart at the bedside’ by Magder most explanatory and practical to guide treatment of the electrolyte disturbances and in exploring the acid-base disorder of the presented case. Introduction This is accompanied by changes in pCO2 and bicarbonate (HCO₃ ) levels, depending on the cause of the acid-base disorder. -

Evaluation of Prolonged Surface Activated Coagulation Time
Biomedical Science Faculty of Health and Society Malm¨oUniversity SE-205 06 Malm¨o Sweden Master programme in Biomedical Surface Science http://edu.mah.se/en/Program/VABSE Evaluation of prolonged surface activated coagulation time Master degree thesis, 30 ECTS Author: Amalie Jesting Supervisors: Sebastian Bj¨orklund,PhD, Lecturer, Malm¨oUniversity Jens Peter Gøtze, MD, DMSc Professor, Chief-Physician, Rigshospitalet Søren Frank Jørgensen, MSc, Senior Lecturer, Metropolitan University College August 2018 MALMO¨ UNIVERSITY Abstract Faculty of Health and Society Master programme in Biomedical Surface Science Evaluation of prolonged surface activated coagulation time by Amalie Jesting Background: Blood coagulation is an essential defense mechanism to prevent bleeding. Disorders in the coagulation system can be severe and blood tests measuring the blood's ability to coagulate are important. Activated partial thromboplastin time (APTT) is a blood test that measures blood coagulation time. An abnormal prolonged APTT can both be associated with a bleeding tendency or a risk of thrombosis. Additional blood tests are needed to discover the cause of a prolonged APTT. One potential test is the APTT mixing study, which can separate samples with and without inhibitors. The aim of this project is to investigate how the cause of a prolonged APTT is evaluated today and to examine if it is possible to indicate the cause of a prolonged APTT using the APTT mixing study performed on routine samples. The goal is to be able to indicate the cause of a prolonged APTT immediately when is it first discovered. This will save time and help guide the physicians in their work with the patient. -

A Life-Threatening Case of Pregnancy-Related Atypical
Puri et al. BMC Nephrology (2020) 21:488 https://doi.org/10.1186/s12882-020-02100-4 CASE REPORT Open Access A life-threatening case of pregnancy- related atypical Haemolytic uremic syndrome and successful treatment with Eculizumab Prianka Puri1,2* , Anida Hanxhiu1, Daniel V. O’Hara1,3, Danny Hsu4 and Mirna Vucak-Dzumhur1,5 Abstract Background: Pregnancy-related Atypical Haemolytic Uremic Syndrome (P-aHUS) is a rare condition affecting genetically predisposed women during pregnancy. It is often difficult to diagnose and has a significant impact on maternal and foetal outcomes. It is characterised by microangiopathic haemolytic anaemia and kidney injury from thrombotic microangiopathy. Case presentation: A 27-year-old female of Lebanese descent presented at 36 weeks’ gestation with foetal death in-utero (FDIU) with placental abruption on a background of previously normal antenatal visits. She was coagulopathic and anaemic with anuric acute kidney injury, requiring emergency Caesarean section, intubation and dialysis. Her coagulopathy rapidly resolved, however, her anaemia and renal dysfunction persisted. A diagnosis of P-aHUS was made, and she was empirically treated with Eculizumab. Her ADAMTS13 level was normal, effectively excluding thrombotic thrombocytopenic purpura. Within 2 weeks of treatment her haematological parameters improved, and her renal function began to recover and within 2 months she became dialysis independent. Conclusion: This case highlights the challenges of a timely diagnosis of P-aHUS from other pregnancy-related diseases. Although our patient is dialysis-independent, her risk of relapse remains high with subsequent pregnancies. Currently we are awaiting her genetic sequencing to complete her assessment for underlying mutations and are determining the safest approach to a future planned pregnancy. -
