Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person’s own red blood cells (RBCs) cause them to burst (lyse), leading to. Autoimmune hemolytic anemia (AIHA) is an uncommon disorder characterized by hemolysis mediated by autoantibodies directed against. Autoimmune hemolytic anemia is characterized by shortened red blood cell survival and a positive Coombs test. The responsible autoantibodies may be either.

Most of the cold autoimn are directed against I antigen and I antigen negative donor units are extremely rare, so red cell transfusion may potentiate hemolysis. Corticosteroids are first-line therapy. For secondary CAS, treating the underlying disease is the main stay of treatment. Autoimmune hemolytic anemia associated with an IgA autoanti-Gerbich. A fatal case of ceftriaxone Rocephin -induced hemolytic anemia associated with intravascular immune hemolysis.

Autoimmune hemolytic anemia – Wikipedia

Diabetes mellitus type 1 Hashimoto’s thyroiditis Multiple sclerosis Coeliac disease Giant-cell arteritis Postorgasmic illness syndrome Reactive arthritis. Mixed-type can, like the others, present unusually with positive reactions to other antisera. Although MeSH uses the term “autoimmune hemolytic anemia”, [5] some sources prefer the term “immunohemolytic anemia” so drug reactions can be included in this category. Nearly half of all warm antibody AIHA patients have autoantibodies specific for epitopes on Rh proteins [ 29303132 ].

The family history in HS, however, often identifies other affected individuals. The relation of erythrocyte antibody production to activity of the disease: The serologic work-up is made complicated by the panagglutinating warm autoantibodies that often mask the existing alloantibodies thus rendering cross-match incompatible. Bull N Y Acad Med. Specificity of acquired haemolytic anaemia autoantibodies and their serological characteristics.


The manual method has the disadvantage that it is least sensitive for detection of red cell bound Ig. Secondary cold agglutinin hemolytic anemia Postinfectious e.

Williams Hematology, 9th ed. Secondary AIHA can result from many other illnesses. Autkimun acquired hemolytic anemia: J Med Case Reports. Each has a different underlying cause, management, and prognosis, making classification important when augoimun a patient with AIHA. The immune haemolytic anaemias: It is more common in women than in men [ 23 ].

Pathological cold autoantibodies are characterized by large thermal amplitude or a high titer, with thermal amplitude as the better predictor of hemolysis. Methods in Hematology — Immune Hemolytic Anemia.

Philadelphia, Churchill Livingstone, In this case, splenectomy may be considered, as well as other immunosuppressive drugs. The DAT remains negative between attacks.

Diagnosis and treatment of autoimmune hemolytic anemia: classic approach and recent advances

Specificity for IgG subclasses and IgG fragments”. National Center for Biotechnology InformationU. The cold hemagglutinin disease.

Annual incidence of warm antibody AIHA is estimated at one per 75, population, occurring in people of all ages [ 3 ]. Secondary mixed AIHA e.

A positive DAT test has poor specificity for AIHA having many differential diagnoses ; so supplemental serological testing is required to ascertain the cause of the positive reaction. A high-titer, high-thermal amplitude autoanti-B associated with acrocyanosis but no obvious hemolytic anemia.

Drugs can produce hemolysis by both immune and non-immune mechanisms. Steroids and splenectomy are less efficacious in cold agglutinin disease. Acquired Immune Hejolitik Anemias.

Diagnosis and treatment of autoimmune hemolytic anemia: classic approach and recent advances

Serologic findings in in autoimmune hemolytic anemia associated with immunoglobulin M warm autoantibodies. This disorder is characterized by monoclonal IgM cold agglutinins and is considered a special form of monoclonal gammopathy or low-grade lymphoproliferative malignancy. Consumption of complement proteins during hemolysis may lead to depression of complement levels.


Patients hemmolitik more severe disease symptomatic anemia, transfusion dependence may be treated with rituximab. Indian J Hematol Blood Transfus. Hemoglobinuria is rare in warm antibody AIHA but is more common in patients with cold agglutinin disease, and especially in patients with paroxysmal cold hemoglobinuria and with some types of drug-induced immune hemolytic anemia.

Am J Clin Pathol. Generally extravascular hemoligik in CAS occurs hemoiltik the liver, so splenectomy has only benefited those patients with IgG cold agglutinins. Spherocytes and RBC fragmentation are noted on the blood film [ 4849 ]. Footnotes Source of Support: Paroxysmal cold hemoglobinuria with its characteristic episodic hemolysis and hemoglobinuria is generally distinguished from chronic cold agglutinin disease, warm antibody AIHA, march hemoglobinuria, myoglobinuria, and PNH by the DAT and Donath-Landsteiner test.

Autoimmune hemolytic anemia: From lab to bedside

Tes Coombs menunjukkan anti-C3 dan ditemukannya cold antibody. Although RBC transfusion is not a contraindication in AIHA, however its use should be limited to cases autoomun life-threatening anemia or a high risk of cardiac or cerebrovascular ischemic events. This is the case in both cold agglutinin disease and cold paroxysmal hematuria.
