The Ceruloplasmin Transferrin Ratio in the Blood of Patients at Different Stages of Parkinson’s Disease

Аннотация

The ratio of the concentrations of Cu²⁺-ceruloplasmin/Fe³⁺-transferrin in the blood plasma of 54 patients at different stages of Parkinson’s disease treated and not treated with L-DOPA was estimated by EPR-spectroscopy. It was established that in patients who suffer from Parkinson’s disease, the value of ceruloplasmin/ transferrin increased by 157% in comparison with the control group of clinically healthy people of the same age group. In patients with Parkinson’s disease, the ratio of ceruloplasmin/transferrin increased at stage 1 of the disease by 119%, at stage 2 by 117%, and at stage 3 by 135% in comparison with the control group. There was no statistically significant difference between the ratio of ceruloplasmin/transferrin in patients who received and did not recive L-DOPA replacement therapy. These data reveal changes in the functioning of the ceruloplasmin: transferrin system, which decreases the content of toxic ions of Fe²⁺ in the plasma of patients with Parkinson’s disease. These changes are a pathogenetically significant factor of Parkinson’s disease at all stages of the disease.
