Immune-mediated hemolytic anemia (IMHA) is a common cause of anemia in dogs. The immune aggression towards erythrocytes can be triggered by many pathological conditions such as infection, inflammatory disease or neoplasia. Upon ruling out any eliciting conditions, a diagnosis of the primary immune-mediated disease can be made. In this particular case of severe anemia (tested positive for circul...

Hemolytic anemia due to immune function is one of the major causes of acquired hemolytic anemia. In recent years, as more is known about the immune system, these entities have become better understood and their treatment improved. In this section, we will discuss three areas in which this progress has been apparent. In Section I, Dr. Peter Hillmen outlines the recent findings in the pathogenesi...

Immune-mediated hemolytic anemia (IMHA) is characterized by the destruction of erythrocytes or sometimes bone marrow erythroid precursors mediated by immunoglobulins (IgG, IgM), with or without complement (C 3). The main objectives of this study were to assess the laboratory test results of IMHA and to investigate its possible underlying causes in cats referring to the Veterinary Teaching Hosp...

Background: Splenic infarction (SI) is a rare clinical entity seldom encountered in veterinary medicine. Its most frequent causes include thromboembolic status, splenomegaly, and cardiac disease. Although thrombotic elements from the circulation provide the most common context for thromboembolic SIs, immune-mediated hemolytic anemia (IMHA) has not been reported as an underlying...

Immune-mediated hemolytic anemia is a well-recognized complication of hematopoietic stem cell transplantation. We report on a 6-year-old boy with X-linked adrenoleukodystrophy who developed severe delayed alloimmune hemolytic anemia associated with immune-mediated neutropenia and thrombocytopenia following major ABO incompatible unrelated cord blood transplantation. The patient's cytopenias wer...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with a variety of clinical manifestations related to viral tissue damage, as well virally induced immune response. Hyperstimulation the system can serve trigger for autoimmunity. Several immune-mediated have been described in course SARS-CoV-2 infection. Immune thrombocytopenic purpura (ITP) and autoimmune hemo...

Background: Atypical hemolytic uremic syndrome (aHUS) is a life-threatening and scarce disorder characterized by acute renal failure and disease, non-immune microangiopathic hemolytic anemia and thrombocytopenia, leading to end-stage renal failure or death, and consequently maybe accompanying by extra renal manifestations. Case report: We reported aHUS accompanied by autoimmune hemolytic anemi...

Abstract Background: Hereditary red cell enzyme disorders are a group of Non-immune/Spherocytic Hemolytic Anemia, although these disorders are rare and they have not public health problems, the detection of these defects could help to physician in treatment and differential diagnosis. This study evaluated 5 enzymopathies in patients with Hereditary Non –immune/Spherocytic Hemolyti...
