Abstract:

Objective

To explore the diagnostic nalue of of C-reactive protein to albumin ratio (CAR) and neutrophil to lymphocyte ratio (NLR) for Parkinson's disease (PD) in elderly patients.

Methords

A total of 87 elderly PD patients (PD group) and 60 patients with headache and dizziness (Control group) were collected from Suqian First Hospital from January 2019 to March 2022. Basic data and blood biochemical indexes of patients in the two groups were collected, and CAR and NLR were calculated. Spearman correlation analysis was used to analyze the correlation of CAR and NLR with disease severity (Hoehn-Yahr stage) and cognitive dysfunction in PD patients. Multivariate logistic regression analysis was used to determine whether CAR and NLR were risk factors for PD. The diagnostic value of CAR and NLR for PD was evaluated using receiver operating characteristic (ROC) curve .

Results

Compared with the control group, the levels of CAR and NLR in PD group were significantly higher, and the difference was statistically significant (t=3.875, 3.212; P < 0.05). Spearman correlation analysis showed that CAR was positively correlated with Hoehn-Yahr stage and cognitive dysfunction in PD patients (r=0.614, 0.712; P < 0.01), while NLR was only positively correlated with cognitive dysfunction in PD patients (r=0.735, P < 0.01). Multivariate Logistic regression analysis showed that CAR and NLR were independent risk factors for PD (OR=2.533, 1.736; 95%CI: 1.662-4.064, 1.437-2.968; P < 0.01). ROC curve analysis results showed that the areas under the curve predicted by CAR and NLR were 0.749 (95%CI: 0.666-0.831, P < 0.05) and 0.751 (95%CI: 0.670-0.833, P < 0.05), respectively. The area under the curve predicted by CAR and NLR was 0.837(95%CI: 0.772-0.903, P < 0.01).

Conclusion

CAR and NLR are associated with the risk, severity and cognitive dysfunction of PD, and can be used as biomarkers to diagnose PD, and their combined diagnostic value is higher.
