Diagnosis Significance of the Levels of Cytokines IL-6, IL-10 and CXCL-13 in Cerebrospinal Fluid for Central Nervous System Infiltration of Lymphoma / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To evaluate the diagnostic value of the expression levels of cytokines interleukin-6(IL-6), interleukin-10 (IL-10) and chemokine （C-X-C motif） ligand-13 (CXCL-13) in cerebrospinal fluid (CSF) for central nervous system infiltration of lymphoma.@*METHODS@#Forty patients diagnosed as lymphoma or acute lymphoblastic leukemia in General Hospital of Northern Theater Command from July 2020 to July 2021 were collected and recorded their CSF indexes, including pressure, protein, Pandy test, nucleated cell count, glucose and chlorine content in CSF. The levels of cytokines IL-6, IL-10 and CXCL-13 were detected by Enzyme-linked immunosorbent assay.@*RESULTS@#The patients were divided into CNSI (central nervous system infiltration) group and non-CNSI group, the average levels of IL-6, IL-10, CXCL-13 and IL-10/IL-6 ratio in CNSI group were higher than those in non-CNS group, but the difference of IL-10/IL-6 ratio between the two groups was statistically significant (P<0.05). Then the patients were divided into protein elevated(n=14) group and protein normal group(n=26), the levels of IL-6 ［ (5.78±2.69) pg/ ml］ and CXCL-13 ［(0.83±0.59) pg/ml］ in protein elevated group were significantly higher than those in the protein normal group ［IL-6 (2.41±1.16) pg/ml; CXCL-13 (0.38±0.18) pg/ml］ (P<0.05). Further analysis of the expression levels of the cytokines in non-CNSI group (n=32), IL-6, IL-10, CXCL-13 level and IL-10/IL-6 ratio in the protein elevated group (n=12) were higher than those in the protein normal group (n=20), but the difference was not statistically significant.@*CONCLUSION@#The levels of IL-6, IL-10 and CXCL-13 in CSF of lymphoma patients with CNS infiltration were higher than those in non-CNS infiltration group, and those in patients with protein elevated group are higher than those in the protein normal group.
