Peripheral blood smear in patient with thrombotic thrombocytopenic purpura. Typical schistocytes are annotated. A schistocyte or schizocyte (from Greek schistos for "divided" and kytos for "hollow" or "cell") is a fragmented part of a red blood cell. Schistocytes are typically irregularly shaped, jagged, and have two pointed ends. [1]
Schistocytes or helmet cells . Diagnosis. Microangiopathic hemolytic anemia results in isolated increase in serum bilirubin levels. Unconjugated hyperbilirubinemia ...
Schistocytes are usually seen in relatively low numbers and are associated with conditions in which the normally smooth endothelial lining, or endothelium, is roughened or irregular, and/or the vascular lumen is crossed by strands of fibrin. [18] Schistocytes are commonly seen in patients that have hemolytic anemia.
Increasingly, however, researchers are wondering if there is a whole-body memory, that is, if different parts of our bodies can also make and store a type of memory, and if so, how these other ...
The presence of schistocytes is a key finding that helps to diagnose HUS. Shiga-toxin directly activates the alternative complement pathway and also interferes with complement regulation by binding to complement factor H, an inhibitor of the complement cascade.
Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections. [1] [2] A similar term is spur cells. Often they may be confused with echinocytes or schistocytes.
Hemangiosarcoma can cause a wide variety of hematologic and hemostatic abnormalities, including anemia, thrombocytopenia [7] (low platelet count), disseminated intravascular coagulation (DIC); presence of nRBC, schistocytes, and acanthocytes in the blood smear; and leukocytosis with neutrophilia, left shift, and monocytosis.
In some cases, a drug can cause the immune system to mistakenly think the body's own red blood cells are dangerous, foreign substances. Antibodies then develop against the red blood cells. The antibodies attach to red blood cells and cause them to break down too early. It is known that more than 150 drugs can cause this type of hemolytic anemia ...
