Although neuroinflammation is known to play an important role in the pathogeneses of neurodegenerative diseases, few studies have been conducted on the association between Parkinson's disease (PD) and high-sensitivity C-reactive protein (hs-CRP), which is the most studied biomarker of systemic inflammation. Therefore, we conducted this study to determine the clinical correlates of hs-CRP levels in early PD patients by comparing findings with those of normal controls. Sixty-three drug-naïve patients with early PD and 117 healthy subjects were recruited, and hs-CRP level differences were investigated in these two groups. It was found that hs-CRP levels in the early PD group were higher than those of healthy controls. Furthermore, when compared with normal controls, the odds ratio for PD based on hs-CRP level cut-off of 0.5 was 2.094 (95% CI = 1.017-4.311, P = 0.045). In this study, our findings support the hypothesis that neuroinflammatory reactions play an important role in the pathogenesis of PD.
