Liver alcoholic cirrhosis and spur-cell (acanthocytic) anaemia. A study of erythrocyte ghost composition and fluidity.
BACKGROUND
The occurrence of spur-cell anaemia in the course of cirrhosis is rare. Alterations of the lipid composition and fluidity of erythrocyte (RBC) ghosts may be present and participate in the phenomenon.


METHODS
A 59-year-old male patient with alcoholic cirrhosis developed severe spur-cell haemolytic anaemia before death. We compared his RBC ghosts with those of 10 cirrhotic patients and used a group of 9 healthy subjects as controls.


RESULTS
The cholesterol to protein ratio was higher in cirrhotic patients; besides, they had less unsaturated fatty acid. The ratio of phospholipid phosphorus to protein did not change; yet, the distribution of phosphorus among phospholipid classes was altered. No difference in 1,6-diphenyl-1,3,5-hexatriene fluorescence anisotropy (membrane fluidity) was observed between the ghosts of cirrhotic patients and those of healthy people. However, the ghosts of the patient with spur-cell anaemia were more rigid than those of either group.


CONCLUSIONS
The values of most variables of cirrhotic patients' ghosts lay between those of healthy subjects and those of the one who developed spur-cell anaemia. It is concluded that some homeostatic mechanisms must control fluidity during cirrhosis; in some cases alterations are particularly great, and fluidity cannot be maintained.
