Abstract:
OBJECTIVE:To explore the correlation between the changes of T lymphocyte subsets and cytokines in patients with MM and immune function status, biochemical indicators, and their relationships with clinical stage and prognosis, which is expected to provide a scientific basis for the prognosis analysis and condition monitoring of MM patients.
METHODS:The clinical data of 89 MM patients in two hospitals were collected, and 36 healthy people without tumor or infectious diseases were selected as the control group. Flow cytometry and enzyme-linked immunosorbent assay (ELISA) were used to detect the changes of core members of peripheral blood T lymphocyte subsets and cytokine levels, respectively. At the same time, automatic biochemical analyzer and automatic blood cell analyzer were used to detect serum β2-microglobulin (β2-MG), lactate dehydrogenase (LDH), albumin (ALB), creatinine (CRE) and hemoglobin (HGB) levels, and the relationship between T lymphocyte subsets and the above indexes and their clinical significance were analyzed.
RESULTS:The proportions of NK cells and CD8+T lymphocytes in the peripheral blood of MM patients were significantly higher than that of the control group (P<0.01), the proportion of CD4+T and the ratio of CD4+/CD8+ were lower than those of the control group (P<0.05); however, there was no significant difference in the numbers CD3+T cells compared with the control group (P>0.05). The proportion of CD4+T and ratios of CD4+/CD8+ in MM patients were lower than those of normal controls, and were negatively correlated with MM staging (r=-0.964, r=-0.653), that is, the later the MM staging, the more obvious their levels were reduced, while CD8+T and NK cells were positively correlated with MM staging (r=0.891, r=0.728), that is, the later the MM staging, the more significant their levels increased. The levels of Treg cells (CD4+CD25highCD127low/-T cells/CD4+T cells) of MM patients in the disease stage Ⅰ, Ⅱ and Ⅲ were (5.87±0.92)%, (7.97±1.32)%, (11.52±4.71)% respectively, the difference was statistically significant compared with control group (P<0.05), and the level of Treg cells in MM patients with stage III was significantly higher than that in controls and patients with other disease stages (P<0.01). The proportion of Treg cells (CD4+CD25highCD127low/-T cells/CD4+T cells) in MM patients was positively correlated with the concentration of β2-MG and LDH (r=0.793, r=0.536), but had no significant correlation with HGB, ALB and CRE. The serum levels of IL-6, IL-10 and TNF-α in MM patients were significantly higher than those in the control group (P<0.05), which were closely related to MM staging(r=0.839, r=0.917, r=0.746), that is, the later the MM staging, the higher the levels; The serum IFN-γ level was negatively correlated with the stage of MM (r=-0.689), and its level gradually decreased with the increase of the disease stage and degree (P<0.01). There was no significant correlation between the levels of IL-2 and IL-4 and the disease stage, but they were all up-regulated compared with the control group (P<0.05).
CONCLUSION:The abnormal regulation of the core members of T lymphocyte subsets and the levels of various cytokines are closely related to the disease progression and poor prognosis of MM patients, which is an effective indicator for the disease monitoring of MM patients.
