Abstract：Objective To evaluate the value of PCT in diagnosis of bacterial infection in patients with autoimmune disease. Methods 181 AID patients were enrolled into this study.The levels of PCT,CRP,ESR and WBC were detected by routine ex-perimental protocols.The sensitivity and specificity of these indexes in diagnosis of bacterial infection in patients with autoim-mune disease were compared.Results In patients with AID,the levels of PCT and CRP in bacterial infection group were much higher than that in the non -infection group(P <0.05).However,when it came to WBC and ESR,there were no significant differences between two groups (P >0.05).The ROC showed that PCT had a better sensitivity and specificity in diagnosis of bacterial infection in AID patients.While in non -active SLE patients,CRP had a better sensitivity and specificity in diagnosis of bacterial infection according to the ROC.Conclusion Elevated PCT levels had a good diagnostic value for infection in pa-tients with AID,and it differs in different diseases and disease activity.
