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).
The test was premature and was forgotten. In 1946, Boorman, Dodd, and Loutit applied the direct antiglobulin test to a variety of hemolytic anemias, and laid the foundation for the clear distinction of autoimmune from congenital hemolytic anemia. [citation needed] A hemolytic state exists whenever the red cell survival time is shortened from ...
An appropriate course of treatment for drug-induced autoimmune hemolytic anemia hasn't yet been established. Once DIIHA has been recognized, the patient must stop whatever drug caused the anemia in order to provide proper treatment. Patients should be given blood transfusions as needed.
Its overall phenotype resembles a combination of autoimmune hemolytic anemia and immune thrombocytopenic purpura. [1] [4] [5] Autoimmune hemolytic anemia is a condition in which the red blood cells that normally carry oxygen are destroyed by an autoimmune process. Immune thrombocytopenic purpura is a condition in which platelets are destroyed ...
Prednisone. Treatment of hepatomegaly varies with the cause, so accurate diagnosis is the first concern. In auto-immune liver disease, prednisone and azathioprine may be used for treatment. [3] In lymphoma the treatment options include single-agent (or multi-agent) chemotherapy and
Mixed autoimmune hemolytic anemia (MAIHA) is a type of autoimmune hemolytic anemia which combines the features of cold sensitive antibody-induced diseases and warm autoimmune hemolytic anemia. The work-up for diagnosis is complex and the condition can be over-diagnosed. [1] [2] [better source needed]
In drug-induced nonautoimmune hemolytic anemia, red blood cells (RBC) are destroyed from various non-immune mechanisms such as direct oxidative stress from certain drugs. [1] This is in contrast to drug-induced autoimmune hemolytic anemia where certain drugs result in the formation of antibodies against RBCs, resulting in hemolysis.
Pure red cell aplasia (PRCA) or erythroblastopenia refers to a type of aplastic anemia affecting the precursors to red blood cells but usually not to white blood cells. In PRCA, the bone marrow ceases to produce red blood cells. There are multiple etiologies that can cause PRCA. The condition has been first described by Paul Kaznelson in 1922. [1]
