(1) Abetalipoproteinemia, see there.(2) A general term for the presence of acanthocytes in the peripheral blood.
Aetiology
Hereditary abetalipoproteinemia (hereditary acanthocytosis) accompanied by decreased total serum lipids, phospholipids, cholesterol, vitamin E, vitamin A; severe (end-stage) liver disease; hepatorenal failure; anorexia nervosa; chronic starvation. Small number of acanthocytes may be seen in severe haemolytic anaemia, especially post-splenectomy; haemolytic anaemia due to pyruvate kinase deficiency and intravascular mechanical defects (e.g., cardiac valve protheses, synthetic intravascular grafts and fibrin in DIC) in neonatal hepatitis after heparin administration; and rarely also in otherwise normal blood smears (one or 2 per smear), where they correspond to older, effete red cells approaching the end of their 120-day life-cycle.
