Ceruloplasmin in Parkinson's disease and the nonmotor symptoms.

Objectives: To investigate the relationship between ceruloplasmin (CP) and Parkinson's disease (PD), and the correlation between CP level and the time difference between nonmotor symptoms and motor symptoms and the diagnosis were also mentioned. Materials and Methods: Sixty-six patients diagnosed with PD for the first time were included in the study. They were divided into CP reduction group (31 cases) and CP normal group (35 cases) according to their CP level. The estimated time difference between nonmotor symptoms and motor symptoms and the diagnosis were recorded respectively. The magnetic sensitive nigra phase value was measured by susceptibility weighted imaging (SWI). Results: Ceruloplasmin level was middling correlated with age (r = .561, p < .001). There was strong negative correlation between CP level and UPDRS scores (r = -.727, p < .001). The CP level was significantly correlated with the magnetic sensitive nigra phase value (r=.891, p < .001). CP level showed moderate correlation with the time difference from nonmotor symptoms to motor symptoms (r = .559, p<.001), besides, the time difference between nonmotor symptoms and the diagnosis (r = .525, p<.001) and CP level was also moderately related. Conclusions: Ceruloplasmin interference in iron metabolism was closely related with PD development. And there were slight correctionsbetween CP level and the time difference from nonmotor symptoms to motor symptoms or the diagnosis.
