We evaluated chemokine expression and its correlation with disease activity in patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) (MPA/GPA). Serum CCL2, CCL4, CCL19, CXCL1, CXCL2, and CX3CL1 level in 80 patients were analysed using multiple enzyme-linked immunosorbent assays. Correlations between variables were investigated using Pearson’s correlation analysis, and receiver operator curve analysis was performed to identify optimal CX3CL1 values in determining active disease. Multivariate logistic regression analysis was done to evaluate predictors of active disease. CCL4 (r = 0.251, p  = 0.025), CXCL1 (r = 0.270, p  = 0.015), and CX3CL1 (r = 0.295, p  = 0.008) significantly correlated with BVAS, while CX3CL1 was associated with five-factor score (r =  − 0.290, p  = 0.009). Correlations were revealed between CCL2 and CCL4 (r = 0.267, p  = 0.017), CCL4 and CXCL1 (r = 0.368, p  < 0.001), CCL4 and CXCL2 (r = 0.436, p  < 0.001), and CXCL1 and CXCL2 (r = 0.518, p  < 0.001). Multivariate analysis revealed serum CX3CL1 levels > 2408.92 pg/mL could predict active disease (odds ratio, 27.401, p  < 0.001). Serum chemokine levels of CCL4, CXCL1, and CX3CL1 showed association with disease activity and especially, CX3CL1 > 2408.92 pg/mL showed potential in predicting active MPA/GPA.
