Abstract
The present study has examined the relationship and significance of hypocholesterolaemia to anaemia and to the red cell. The level of plasma cholesterol is closely related to haematocrit levels both initially and throughout the course of the anaemias associated with hypocholesterolaemia. The association is maintained, regardless of the cause of the haematocrit change, i.e. transfusion or response to treatment. Hypocholesterolaemia does not affect the red cell, i.e. its survival, cholesterol concentration or osmotic fragility and occurs in a diverse group of anaemias. As such, it is not causally related to anaemia. The changes in plasma cholesterol are most likely related to its 'redistribution' or to plasma 'dilution', with contributory factors occurring. The presence of anaemia, even to a modest degree, would be important to consider when comparing cholesterol levels between groups of individuals.
