The general information of patients was retrospectively collected. MRI was used to assess IVDD severity using the Pfirrmann grading system. Serum GPR4 and BGN levels were measured by enzyme-linked immunosorbent assay (ELISA). Multiple linear regression analysis was performed to identify risk factors for IVDD severity. Spearman’s and Pearson’s correlation analyses were used to evaluate the relationships between serum GPR4, BGN, and IVDD severity. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of serum GPR4 and BGN in IVDD.Results: Significant differences in age and the proportion of diabetic patients as well as serum GPR4 and BGN were found among different Pfirrmann grades (P< 0.05). Serum GPR4 levels increased but BGN levels decreased with higher Pfirrmann grades (P< 0.05). Multiple linear regression analysis showed that age and serum GPR4 and BGN levels were risk factors for IVDD severity (P< 0.05). The results of the correlation analysis showed that serum GPR4 and age were positively correlated with the severity of IVDD (r=0.651, r=0.488, P< 0.001), while BGN was negatively correlated with the severity of IVDD (r=− 0.591, P< 0.001). The results of Spearman correlation analysis showed a negative correlation between serum GPR4 and BGN (P< 0.05). ROC curve analysis revealed that the AUC values for the diagnosis of IVDD using serum GPR4 alone, BGN alone, and the combination of GPR4 and BGN were 0.918, 0.811, and 0.919, respectively (P< 0.05). Moreover, the combination of GPR4 and BGN demonstrated higher sensitivity and specificity compared to either marker alone.Conclusions: Serum GPR4 and BGN levels are identified as effective diagnostic indicators for IVDD, with serum GPR4 positively correlated but BGN negatively correlated with the severity of IVDD.Keywords: G protein-coupled receptor 4, biglycan, intervertebral disc degeneration, correlation |
