Abstract:

Objective To investigate the correlation between serum uric acid (UA), homocysteine (HCY) and cystatin C (Cys C) with motor symptoms and cognitive function in Parkinson's disease (PD) patients. Methods A total of 200 PD patients admitted to Hebei General Hospital from January 2019 to August 2022 were enrolled. They were divided into tremor-dominant (TD) group(n=104) and non-tremor-dominant (NTD) group(n=96) according to first-onset motor symptoms. In addition, the PD patients were grouped also into cognitive normal(PD-CN) group(n=118) and cognitive impairment (PD-CI) group(n=82) according to Montreal Cognitive Assessment. The levels of serum UA, HCY and Cys C of the PD patients were compared. Multivariate logistic regression was used to analyze the risk factors of tremor and cognitive dysfunction in PD patients. Results The patients in TD group had significantly higher serum UA levels, significantly lower Hcy and Cys C levels compared with those of the NTD group (P<0.05). The results from multiple logistic regression analysis showed that UA, HCY, and Cys C were independent risk factors for tremor in PD patients. The patients in the PD-CN group pesented significantly higher serum UA levels, significantly lower HCY and Cys C levels relative to those of the PD-CI group (P<0.05). The results from multivariate logistic regression analysis verifyed that UA, HCY, and Cys C were independent risk factors for cognitive dysfunction in PD patients (P<0.05). Conclusion The serum levels of UA, HCY, and Cys C in PD patients are correlated with motor symptoms and cognitive function.
