Practical therapy for primary autoimmune hemolytic anemia in adults.

Clin Exp Med 2022 Aug 18. Epub 2022 Aug 18.

UO di Medicina, Ospedale di Ostuni, via Villafranca SN, Ostuni, BR, Italy.

Background And Aim: Autoimmune hemolytic anemias (AIHA) constitute a rare and heterogeneous group of diseases whose therapy differs according to the type of antibody involved in the genesis of the disease and the existence or not of an identified cause. With the aim of providing a practical guide for the therapy of AIHA, we summarize the emergency therapy and general measures habitually used in all forms of AIHA, as well as the specific treatment of the most frequent primary forms of AIHA: primary warm AIHA and AIHA from cold agglutinin disease (AIHA from CAD). We discuss the dependence of the treatment of the secondary forms on their underlying causes and the changes in the treatment of the primary forms in recent years. Read More

Systemic Lupus Erythematosus Presenting With Thrombotic Thrombocytopenic Purpura at Onset: A Case Report.

Front Pediatr 2022 1;10:931669. Epub 2022 Aug 1.

Department of Pediatrics, Gunma University Graduate School of Medicine, Maebashi, Japan.

Background: Thrombotic microangiopathy (TMA) is a syndrome associated with hemolytic anemia, thrombocytopenia, and various organ disorders. Thrombotic thrombocytopenic purpura (TTP) is a disease that develops when a disintegrin-like and metalloproteinase with thrombospondin type l motif 13 (ADAMTS13) activity decreases to < 10% of that in normal plasma, causing platelet thrombosis in microvessels throughout the body. Currently, ADAMTS13-deficient TMA is diagnosed as TTP. Read More

Longitudinal proteomics study of serum changes after allogeneic HSCT reveals potential markers of metabolic complications related to aGvHD.

Sci Rep 2022 Aug 17;12(1):14002. Epub 2022 Aug 17.

School of Life Science and Technology, Tokyo Institute of Technology, 2-12-1 Ookayama, Meguro-ku, Tokyo, 152-8550, Japan.

Even though hematopoietic stem cell transplantation (HSCT) allows successful treatment for many malignant and non-malignant disorders, its curative potential remains limited by severe side effects, including infections and other transplant-related complications such as graft-versus-host disease (GvHD). This study examined changes in serum proteome via high-performance two-dimensional gel electrophoresis (2-DE) during HSCT to search for diagnostic biomarkers for post-HSCT complications. Longitudinal proteomic analysis revealed proteins related to metabolic complications and hemolytic anemia. Read More

[Diagnostic clues in atypical hemolytic uremic syndrome: a case report].

An Sist Sanit Navar 2022 Aug 17;45(2). Epub 2022 Aug 17.

Servicio de Análisis Clínicos. Hospital Universitario de Navarra. Servicio Navarro de Salud-Osasunbidea. Pamplona. España..

Atypical hemolytic uremic syndrome (aHUS) is a clinical entity characterized by non-immune hemolytic anemia, thrombocytopenia and renal failure, in which lesions are mediated by a systemic thrombotic microangiopathy. It is a rare pathology whose origin is a complement system deregulation due to mutations in its genes that lead to uncontrolled activation of C5 and the formation of the membrane attack complex.- Its correct diagnosis allows us to prescribe the treatment based on Eculizumab, a C5 inhibitor.

Effectiveness of aspirin vs. clopidogrel in dogs with immune mediated haemolytic anaemia evaluated by serial thromboelastography and platelet mapping.

Vet J 2022 Aug 10:105882. Epub 2022 Aug 10.

Sydney School of Veterinary Science, Faculty of Science, University of Sydney, Sydney, Australia; Department of Veterinary Clinical Sciences, Jockey Club College of Veterinary Medicine and Life Sciences, City University of Hong Kong, Hong Kong, China.

Most dogs with immune mediated haemolytic anaemia (IMHA) are hypercoagulable, as measured by thromboelastography (TEG). Thromboelastography-platelet mapping (TEG-PM) has been used to assess platelet function in human patients treated with aspirin or clopidogrel. The aim of this study was to compare platelet thromboxane A-receptor inhibition (TXARI) and platelet adenosine diphosphate (ADP)-receptor inhibition (ADP-RI) as measured by TEG-PM in dogs with primary IMHA receiving aspirin or clopidogrel to determine if TEG-PM might be useful to monitor treatment.

Isolated Respiratory Failure as a Presentation for Early Perinuclear Antineutrophil Cytoplasmic Antibody-Associated Vasculitis.

Cureus 2022 Jul 9;14(7):e26698. Epub 2022 Jul 9.

Internal Medicine, Rutgers Health/Trinitas Regional Medical Center, Elizabeth, USA.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is an autoimmune inflammatory disease that usually affects the small-sized vasculature, most notably of the lungs and kidneys. One of the challenges of suspecting and diagnosing the condition lies in the insidious and unclear symptoms of presentation. In this case report, we discuss the case of a patient who initially presented with solely unclear pulmonary symptoms, without other organ system dysfunction. Read More
