OBJECTIVE: This study aimed to investigate the diagnostic values of serum IL-10 and IL-17 in rheumatoid arthritis (RA) and their correlation with serum protein.

PATIENTS AND METHODS: A retrospective analysis was performed on 116 RA patients admitted to the Yantaishan Hospital (the RA group) and 116 healthy subjects (the control group). Enzyme-linked immunosorbent assay was used to detect the expression levels of serum interleukin (IL)-10, IL-17 and 14-3-3η protein. Pearson analysis was performed to analyze the correlation between the expression levels of serum IL-10, IL-17 and 14-3-3η protein of patients in the RA group, and ROC curve analysis was conducted to measure the diagnostic values of IL-10, IL-17 and their combination in RA.

RESULTS: Patients in the RA group had significantly lower serum IL-10 level and markedly higher IL-17 and 14-3-3η protein levels than those in the control group (p<0.001). Serum IL-10 level was negatively correlated with 14-3-3η protein level in RA patients (r=-0.582, p<0.001). Serum IL-17 level was positively correlated with 14-3-3η protein level in RA patients (r=0.482, p<0.001). Serum IL-10 level was negatively correlated with IL-17 level in RA patients (r=-0.468, p<0.001). The AUC of IL-10 for diagnosing RA was 0.671, with a 95% confidence interval of 0.602-0.741 and a cut-off value of 87.315. The AUC of IL-17 for diagnosing RA was 0.856, with a 95% confidence interval of 0.807-0.905 and a cut-off value of 87.844. The AUC of IL-10 combined with IL-17 for diagnosing RA was 0.887.

CONCLUSIONS: RA patients had remarkably lower serum IL-10 level and significantly higher IL-17 and 14-3-3η protein levels than healthy people. IL-17 has better sensitivity and specificity than IL-10 for diagnosing RA. IL-10 combined with IL-17 is beneficial to improve the diagnostic level of RA, which provides the reference for the diagnosis, treatment and pathogenesis of RA.
