Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst , leading to an insufficient number of oxygen-carrying red blood cells in circulation . The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in ...
Acquired hemolytic anemia can be divided into immune and non-immune mediated forms of ... Autoimmune hemolytic anemia [1] Warm antibody autoimmune hemolytic anemia [1]
Acquired hemolytic anemia is also encountered in burns and as a result of certain infections (e.g. malaria). [ 15 ] [ 18 ] Paroxysmal nocturnal hemoglobinuria (PNH), sometimes referred to as Marchiafava-Micheli syndrome, is a rare, acquired, potentially life-threatening disease of the blood characterized by complement-induced intravascular ...
Symptoms may arise suddenly leading to abrupt onset of severe anemia and hemoglobinuria or develop more gradually and insidiously in the background without patient's consciousness and precaution. [4] [7] Most people with CAD have symptoms of hemolytic anemia (destruction of red blood cells, causing low levels of red blood cells). [8]
Cold agglutinins develop in more than 60% of patients with infectious mononucleosis, but hemolytic anemia is rare. Classic chronic cold agglutinin disease is idiopathic, associated with symptoms and signs in relation to cold exposure.
Initial symptoms of drug-induced autoimmune hemolytic anemia are typically vague and reflect mild, moderate, or severe anemia. Symptoms of DIIHA can manifest within hours to months of the initial drug exposure. [1] DIIHA ranges in severity from severe intravascular hemolysis to milder presentations of extravascular hemolysis. [7]
Autoimmune hemolytic anemia: D59.0-D59.1: Autoimmune hemolytic anemia (AIHA) is a type of hemolytic anemia where the body's immune system attacks its own red blood cells (RBCs), leading to their destruction . [28] [29] Types of AIHA include warm autoimmune hemolytic anemia, cold agglutinin disease, and paroxysmal cold hemoglobinuria.
The most common antibody isotype involved in warm antibody AIHA is IgG, though sometimes IgA is found. The IgG antibodies attach to a red blood cell, leaving their F C portion exposed with maximal reactivity at 37 °C (versus cold antibody induced hemolytic anemia whose antibodies only bind red blood cells at low body temperatures, typically 28–31 °C).
