[Examining the relationship between the electrophoretic mobility of peripheral red blood cells and their sedimentation rate in patients with hemophilia].

The correlation between the erythrocyte sedimentation rate (ESR) and the electrophoretic mobility (EPM) of red blood cells in patients with hemophilia was studied due to the data available in the literature, showing an inverse relation. Anticoagulant-stabilized venous blood was a material to be tested. Patients with severe hemophilia A or B (factor VIII/IX < 1%; the normal values were 50-200%) were examined. The patients were divided into 2 groups: 1) those with an exacerbation of hemorrhagic syndrome and 2) those without an exacerbation. The patients with hemophilia with an exacerbation of the hemorrhagic syndrome showed a certain correlation between ESR and EPM, yielding two type of curves, which corresponded to two subgroups of patients. There was no correlation between EPM and ESR in the no-exacerbation group.
