RESUMEN

ABSTRACT The effect of antiretroviral therapy (ART) on CD4+/CD25hi/CD127low T lymphocyte changes in people living with HIV/AIDS (PLWHA) is still a matter of debate. From October 2015 to December 2019, peripheral blood from 70 cases of PLWHA were collected for the detection of CD4+/CD25hi/CD127low T lymphocytes by flow cytometry. Statistical analysis was performed to detect changes of CD4+/CD25hi/CD127low T lymphocytes in patients with different duration of ART and different treatment effects. We found that the number of CD4+/CD25hi/CD127low T lymphocytes in ART-naive PLWHA were lower than those in healthy volunteers (10.3±٦.٠ cells/uL vs 31.7±8.0 cells/uL, P < 0.05). CD4+/CD25hi/CD127low T lymphocyte counts increased to 17.8±٤.٠ cells/uL 6 months post-ART and 25.0±١١.٩ cells/uL 9 months post-ART, respectively (P < 0.05). There was no significant difference in CD4+/CD25hi/CD127low T lymphocyte counts between PLWHA who reached a complete immune reconstruction after ART and healthy volunteers. The growth of CD4+/CD25hi/CD127low T lymphocyte counts in patients who had baseline CD4 > 200 cells/uL was greater than those who had baseline CD4 ≤ 200 cells/uL (12.6±٤.٦ cells/uL vs 5.6±٥.٠ cells/uL, P = 0.027). CD4+/CD25hi/CD127low T lymphocyte counts were positively correlated with CD4+ T lymphocyte counts (r = 0.923, P < 0.001) and CD4+/CD8+ ratio (r = 0.741, P < 0.001), but were negatively correlated with HIV-VL (r = −0.648, P = 0.000). In conclusion, the results of the present study showed that changes in CD4+/CD25hi/CD127low T lymphocyte counts can be used to assess the effect of ART in PLWHA.

RESUMEN

Objective To analyse the dysfunction of immunity and clinical significance in patients with cardiac cancer.Methods The level of CD4+ CD25hi CD127low Treg cells were detected by flow cytometry (FCM),and serum IL-10 and TGF-β1 levels were determined by enzyme linked immunosorbent assay (ELISA) kit in 56 patients with cardiac cancer.15 healthy volunteers were tested as normal controls.The clinical data of each patient were collected and analyzed. Results There was a significantly higher percentage of CD4+ CD25hi CD127low Treg cells in patients with cardiac cancer (5.73±1.56)% than that (4.45±1.06)% of healthy volunteers (P<0.01).The IL-10 and TGF-β1 levels in the serum of patients with cardiac cancer were also significantly higher than that of healthy volunteers (P<0.05).There was a positive correlation between levels of IL-10.TGF-β1 and the levels of CD4+ CD25hi CD127low Treg cells.The number of CD4+ CD25hi CD127low regulatory T cells in the peripheral blood of cardiac cancer patients were significantly correlated with clinical stages and metastasis lymph node.Conclusion The CD4+ CD25hi CD127low Treg cells in the peripheral blood of cardiac cancer patients is significantly increased in comparison with that in healthy volunteers,and was also correlated with different stages.The abnormal levels of CD4+ CD25hi CD127low Treg cells may be related to tumor progression in patients with cardiac cancer.
