Abstract
Hereditary spherocytosis and β thalassaemia are rarely inherited together. We have studied a large family of Caucasian extraction in whom these two diseases segregate independently over four generations. The diagnosis rested on specialized laboratory findings and in a number of subjects on the measurement of α and β globin chain synthesis. In addition, a viscometric method (osmotic gradient ektacytometry) was used to evaluate the rheological function of the erythrocytes. In patients inheriting both diseases, the results indicate that the clinical and biological expression of hereditary spherocytosis is modulated by the degree of imbalanced globin chain synthesis. The opposite properties of spherocytes (decreased surface/volume ratio, increased haemoglobin concentration) and thalassaemic red cells (increased surface/volume ratio, decreased haemoglobin concentration) may explain the antagonistic influence of each genotype.This publication has 9 references indexed in Scilit:
