Features of erythrocyte electrophoretic mobility in programmed hemodialysis patients

Objective: to analyze the electrophoretic properties of erythrocytes in patients receiving programmed hemodialysis treatment. 
Materials and Methods. The study included 100 patients with an established diagnosis of stage 5D chronic kidney disease, receiving programmed hemodialysis treatment. The control group included 17 healthy blood donors. The following indicators of erythrocyte electrophoretic activity were evaluated: oscillation amplitude, percentage of motile cells, ellipticity, and aggregation index. 
Results. Compared with the control group, we revealed significant changes in the amplitude of oscillations and the percentage of motile cells (p<0.001). No significant gender-dependent differences were observed (p>0.05). Statistically significant differences between young and senile age groups (p=0.048) were observed in the average oscillation amplitude, whereas ellipticity differed significantly in middle-aged vs. senile patients (p=0.040) and elderly vs. senile subjects (p=0.035). As for the effect of hemodialysis treatment duration, a reduction in the oscillation amplitude was observed when comparing maximum with minimum duration: less than 1 year (p=0.029) and 1 year (p=0.035). Aggregation index values were the highest in the groups with the minimum (p=0.044) and maximum (p=0.035) dialysis duration. 
Conclusion. In hemodialysis patients, the oscillation amplitude of erythrocytes was significantly reduced, with assumed tendency for further decrease associated with duration of hemodialysis treatment.
