ABSTRACT
OBJECTIVE:
To evaluate the clinical and laboratory correlation of biomarkers with anti- and pro-apoptotic activity with the severity of motor and non-motor symptoms depending on the progression rate of Parkinson's disease (PD). MATERIAL ANDMETHODS:
A wide range of non-motor symptoms (emotional-affective, cognitive, psychotic and behavioral disorders, fatigue, sleep disorders and autonomic disorders) was evaluated using validated scales and a number of serum neuromarkers responsible for neuroplasticity and neuronal survival processes (BDNF, PDGF, cathepsin D) in 71 patients with PD (mean age 65 (55; 70) years, disease duration 7 (4; 9) years, age of onset 57 (49; 62) years).RESULTS:
The concentration of biomarkers (BDNF, PDGF and cathepsin D) was the lowest in the group of patients with a rapid PD progression rate (p<0.001, p=0.001 and p=0.031, respectively), the severity of motor and most non-motor symptoms was higher (p=0.023 and p=0.001, respectively) compared to middle and slow progression rate. There were correlations between BDNF concentration and the severity of depression (r=-0.63, p<0.001), apathy (r=-0.48, p<0.001), impulsive behavioral disorders (r=0.500, p<0.001), level of cognitive functions (r=0.54, p<0.001), motor symptoms (r=-0.43, p<0.001); between PDGF level and the severity of motor manifestations of PD (r=-0.30, p=0.011), depression (r=-0.70, p<0.001), apathy (r=-0.460, p<0.001), the degree of severity of behavioral disorders (r=0.742, p<0.001). No significant correlations were observed between the level of cathepsin D and the severity of clinical manifestations of PD, which indicates the connection of cathepsin D with the general pathogenesis of PD.CONCLUSION:
The possibility of using serum proteins of the neurotrophin subfamily and the protein associated with autophagy, cathepsin D, as biomarkers that determine the prognosis of PD, is considered.Palabras clave
