Further, very similar correlations were obtained between Parkinson’s Disease Rating Scale-3 (UPDRS-3) and CSF inflammatory markers where the UPDRS-3 score correlated with CRP (p = 0.025, β = 0.138), SAA (p < 0.001, β = 0.205), IL-8 (p = 0.032, β = 0.134) and MCP-1 (p = 0.020, β = 0.150). Here, CXCL8 is linked to Parkinson disease.
