Correlation between Serum Interleukin-33, β2-Microglobulin Levels and DS Stage in Patients with Multiple Myeloma / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the correlation between serum interleukin-33 (IL-33), β2microglobulin (β2-MG) levels and Durie-Salmon (DS) stage in patients with multiple myeloma (MM).@*METHODS@#100 MM patients admitted to the First Affiliated Hospital of Fujian Medical University from March 2019 to January 2021 were selected and divided into stage I, stage II and stage III groups according to the DS staging system. A baseline data questionnaire of patients was designed, then the relevant baseline data and laboratory test results of patients were recorded. The levels of serum IL-33 and β2-MG of all patients were detected, and the correlation between serum IL-33, β2-MG levels and DS stage of MM patients was analyzed.@*RESULTS@#Among the 100 patients with MM, there were 32 cases in stage I, 39 cases in stage II and 29 cases in stage III. The levels of serum CRP and β2-MG of patients in stage III were significantly higher than those of patients in stage I and II, and the levels of serum CRP and β2-MG of patients in stage II were significantly higher than those of patients in stage I, the differences were statistically significant (P <0.05). The level of serum IL-33 of patients in stage III was significantly lower than that of patients in stage I and II, and the level of serum IL-33 of patients in stage II was significantly lower than that of patients in stage I, the differences were statistically significant (P <0.05). There was no statistical significant difference in other data between groups (P >0.05). Kendall's tau-b correlation analysis showed that the levels of serum CRP and β2-MG were positively correlated with DS stage in MM patients (r =0.534, 0.776), the level of serum IL-33 was negatively correlated with DS stage in MM patients (r =-0.759). Ordered logistic regression analysis and forest plot showed that the low level of serum IL-33 and the high level of β2-MG were the influencing factors of high DS stage in MM patients (P <0.05 ).@*CONCLUSION@#DS stage of MM patients is closely related to the levels of serum IL-33 and β2-MG, that is, the lower the serum IL-33 level and the higher the β2-MG level, and the higher the DS stage of MM patients.
