Abstract：Objective: To investigate the correlation between serum interleukin-32(IL-32), soluble advanced glycation end-product receptor (sRAGE) and neutrophil/lymphocyte ratio (NLR) and multiple myeloma complicated with kidney injury. Methods: A total of 82 MM patients diagnosed and treated in Rugao People's Hospital from June 2020 to June 2022 were selected as the observation group, and were divided into renal injury group (n=27) and non-renal injury group (n=55) according to renal function, and 41 healthy physical examination patients were selected as the healthy control group during the same period. IL-32, sRAGE and NLR levels were compared. Binary Logistic regression was used to analyze the effects of IL-32, sRAGE and NLR on kidney injury in MM patients. ROC curve model was used to analyze the AUC value, sensitivity and specificity of IL-32, sRAGE and NLR in predicting kidney injury in MM patients. Results: IL-32 and NLR in observation group were higher than those in control group, while sRAGE was lower than those in control group (P<0.05). IL-32 and NLR in renal injury group were higher than those in control group, while sRAGE was lower (P<0.05). Logistic regression model analysis showed that increased IL-32, increased NLR and decreased sRAGE levels were risk factors for kidney injury in multiple myeloma patients (P<0.05). ROC curve analysis showed that the AUC values of serum IL-32, sRAGE and NLR in predicting kidney injury in multiple myeloma patients were 0.761, 0.765 and 0.802, P<0.05. Conclusion: Serum IL-32, sRAGE, and NLR expression levels increased with kidney injury in MM patients.
