Paroxysmal cold hemoglobinuria (PCH) is a rare form of cold autoimmune hemolytic anemia first discovered in the early 20th century in adults with tertiary syphilis. Today, it is more commonly seen in children as a life-threatening anemia during a viral upper respiratory tract infection (URI). Although respiratory syncytial virus (RSV) has previously been reported to cause PCH in a child, herein we present the first documented case in an adult. Read More

Donath-Landsteiner haemolytic anaemia (DLHA), also known as paroxysmal cold haemoglobinuria, is a very rare and difficult condition to diagnose as well as treat. Here, we present a case of a 55-year-old Hispanic woman who presented with severe intravascular haemolytic anaemia in the setting of a viral illness 2 weeks prior to presentation. Direct antiglobulin testing revealed mixed results: positive for either complement, IgG or both on various occasions which led to a battery of tests including the Donath-Landsteiner antibody testing which turned out positive establishing the diagnosis of DLHA.

Autoimmune hemolytic anemia (AIHA) is caused by auto-antibodies directed against self red blood cell (RBC) surface antigens. A consequence may be an intravascular hemolysis mediated by activated complement or extravascular hemolysis caused by destruction of complex of RBC with autoantibody in spleen and liver. The basic classification subdivides AIHA in primary/idiopathic and secondary with known underlying disease. Read More

The classical complement pathway and, to some extent, the terminal pathway, are involved in the immune pathogenesis of autoimmune hemolytic anemia (AIHA). In primary cold agglutinin disease (CAD), secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria, the hemolytic process is entirely complement dependent. Complement activation also plays an important pathogenetic role in some warm-antibody AIHAs, especially when immunoglobulin M is involved. Read More

Paroxysmal cold haemoglobinuria (PCH) is a form of autoimmune haemolytic anaemia (AIHA) characterised by a sudden onset of haemoglobinuria, either spontaneously or following exposure to cold. In children, it is commonly seen following a viral illness or after immunisation. Diagnosis of PCH is confirmed by a positive Donath Landsteiner (DL) test in which biphasic haemolysins are detected.

Autoimmune hemolytic anemia (AIHA) is a disease process that involves the destruction of red blood cells mediated by the humoral immune system. It can be characterized as a cold agglutinin syndrome, paroxysmal cold hemoglobinuria, and warm, mixed type, and drug-induced AIHA. Although a well-established relationship exists between the presence of AIHA and lymphoproliferative malignancy, AIHA rarely presents in association with solid malignancies. Read More

Background: Paroxysmal cold hemoglobinuria (PCH) is a form of autoimmune hemolytic anemia caused by the Donath-Landsteiner antibody (D-L antibody). In children, this is typically a transient immune-mediated hemolysis that follows a viral illness and does not recur. Recurrent acute or chronic PCH due to D-L antibody is very rare. Read More

The complement system is an essential part of the innate immune system that requires careful regulation to ensure responses are appropriately directed against harmful pathogens, while preventing collateral damage to normal host cells and tissues. While deficiency in some components of the complement pathway is associated with increased susceptibility to certain infections, it has also become clear that inappropriate activation of complement is an important contributor to human disease. A number of hematologic disorders are driven by complement, and these disorders may be termed "complementopathies". Read More

Autoimmune hemolytic anemia (AIHA) in childhood, including paroxysmal cold hemoglobinuria, is an uncommon, potentially life-threatening disorder. AIHA is a recognized complication of several varieties of lymphoproliferative disorders, including high-grade B-cell lymphoma, but it has not been associated with Burkitt lymphoma in people without an underlying immunodeficiency. When AIHA occurs in association with lymphoproliferative disorders, it may precede or accompany the diagnosis of malignant disease or herald relapse. Read More

Background: Paroxysmal cold hemoglobinuria (PCH) is a rare form of autoimmune hemolytic anemia caused by a biphasic (Donath-Landsteiner [DL]) immunoglobulin G autoantibody. Estimates of disease frequency after syphilis are lacking and the diagnostic yield of testing for PCH is uncertain. The objectives of this study were: 1) to describe DL testing practices in Canada, 2) to determine how often a biphasic RBC antibody is detected in adults and children, and 3) to evaluate inter-rater reliability of interpretations of positive DL test results in adults.

Objective: The objective of this study was to describe complement activation in hemostatic and pathologic states of coagulation and in the acquired and congenital hemolytic anemias.
Methods And Results: We review published and emerging data on the involvement of the classic, alternative and lectin-based complement pathways in coagulation and the hemolytic anemias. The alternative pathway in particular is always "on," at low levels, and is particularly sensitive to hyper-activation in a variety of physiologic and pathologic states including infection, autoimmune disorders, thrombosis and pregnancy, requiring tight control predicated on a variety of soluble and membrane bound regulatory proteins.

The classification of autoimmune hemolytic anemias and the complement system are reviewed. In autoimmune hemolytic anemia of the warm antibody type, complement-mediated cell lysis is clinically relevant in a proportion of the patients but is hardly essential for hemolysis in most patients. Cold antibody-mediated autoimmune hemolytic anemias (primary cold agglutinin disease, secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria) are entirely complement-mediated disorders.

Complement is increasingly being recognized as an important driver of human disease, including many hemolytic anemias. Paroxysmal nocturnal hemoglobinuria (PNH) cells are susceptible to hemolysis because of a loss of the complement regulatory proteins CD59 and CD55. Patients with atypical hemolytic uremic syndrome (aHUS) develop a thrombotic microangiopathy (TMA) that in most cases is attributable to mutations that lead to activation of the alternative pathway of complement.

Hemolytic anemias consist of corpuscular, immun-hemolytic and toxic hemolytic anemias. Within the group of corpuscular hemolytic anemias, except for the paroxysmal nocturnal hemoglobinuria (PNH), all symptoms are caused by underlying heredetiary disorders within the red blood cell membran (hereditary spherocytosis), deficiencies of red cell enzymes (G6PDH- and pyrovatkinase deficiency) or disorders in the hemoglobin molecule (thalassaemia and sickle cell disease). Immune-hemolytic anemias are acquired hemolytic anemias and hemolysis is caused by auto- or allo-antibodies which are directed against red blood cell antigens. Read More

Paroxysmal cold hemoglobinuria is a rare cause of autoimmune hemolytic anemia predominantly seen as an acute form in young children after viral illnesses and in a chronic form in some hematological malignancies and tertiary syphilis. It is a complement mediated intravascular hemolytic anemia associated with a biphasic antibody against the P antigen on red cells. The antibody attaches to red cells at colder temperatures and causes red cell lysis when blood recirculates to warmer parts of the body. Read More

Autoimmune haemolytic anaemias (AIHAs) are extracorpuscular haemolytic anaemias produced by antierythrocyte autoantibodies which cause a shortened red blood cell life span. There are several reasons why the diagnosis and treatment of AIHAs in children represent a bigger challenge than in adult patients, including the presence of particular AIHA types, the uncertainty of serological tests and the limited clinical experience. All these facts have added up to a poor understanding and management of some topics in childhood AIHA. Read More

In children, paroxysmal cold hemoglobinuria (PCH) is generally considered an acute self-limited autoimmune hemolytic anemia caused by an IgG biphasic auto-anti-P antibody identified by the Donath-Landsteiner (D-L) test. We report a case of a 5-year-old female with a chronic hemolytic anemia. The etiology of the hemolysis appears to be an unusual D-L positive, IgM antibody with specificity for the I antigen.

The complement system is an important part of the innate immune system. Complement plays a crucial role in the pathophysiology of many disorders. Despite the pivotal role of the complement system, an approved targeted inhibitor of a complement factor became available only recently. Read More

Erythrophagocytosis by neutrophils is a rare morphological phenomenon described in patients with clonal malignancies of haematopoiesis with myelodysplasia and in some haemolytic conditions including paroxysmal cold haemoglobinuria, haemolysis caused by snake-bite, sickle cell anaemia and other defects of red cells. We describe a female patient who presented with acquired haemolytic anaemia. Erythrophagocytosis was found in around 35% of neutrophils of the peripheral blood. Read More

Hemolysis and hemoglobinuria after direct exposure to cold has rarely been reported in paroxysmal cold hemoglobinuria (PCH). The authors describe a 2.5-year-old boy with PCH (Donath-Landsteiner autoimmune hemolytic anemia), in whom 16 days after presentation, the hemoglobinuria and hemolysis recurred, when he was subjected to physical cooling, as a means to control fever associated with hospital-acquired croup.

Autoimmune hemolytic Anemia (AIHA) is a uncommon but potentially lethal disorder requiring prompt diagnosis and treatment. Diagnosis is based on clinical and laboratory signs of hemolysis and a positive direct antiglobulin test (DAT). AIHA is classified according to the clinical context (primary or secondary) and the characteristics of the auto-antibody (warm vs. Read More

New linguistic coinage can signify new practices and fresh perceptions in science: descriptors therefore are not trivial. Here, we consider the shifting valence of 'allergic' and 'autoimmune' in conceptions of experimental encephalomyelitis (EE). Ehrlich's dismissal of the relevance to disease of autoimmunity resulted in its 'long struggle for recognition' notwithstanding the convincing attribution in 1904 of the hemolysis of paroxysmal cold hemoglobinuria.
