Abstract:
Objective:To explore the effects of metformin on levels of peripheral blood regulatory T cells (Treg)/Th17 cells and related cytokines in patients with type 2 diabetes mellitus (T2DM) and influenza A.Methods:A total of 108 patients with T2DM and influenza A treated in Zhejiang Veteran Hospital were prospectively enrolled between April 2021 to April 2022. According to different medication methods, they were divided into observation group (54 cases, oseltamivir + metformin) and control group (54 cases, oseltamivir + gliclazide). The average usage time and dosage of oseltamivir, concentration of blood lactate and blood gas level, counts of Th17 and Treg cells, and levels of related cytokines in the two groups were compared before and after treatment.Results:The average usage time and dosage of oseltamivir, and concentration of blood lactate were higher in observation group than control group: (8.94 ± 0.88) d vs. (7.23 ± 0.79) d, (1.32 ± 0.15) g vs. (1.08 ± 0.11) g, (1.83 ± 0.43) mmol/L vs. (1.61 ± 0.32) mmol/L, P<0.05. The differences in pH, partial pressure of arterial oxygen (PaO 2) and partial pressure of arterial carbon dioxide (PaCO 2) between the two groups had no statistically significant before and after treatment ( P>0.05). After treatment, the differences in count of Treg cells, interleukin-10 (IL-10), interleukin-4 (IL-4), CD 3+, CD 4+ and CD 4+/CD 8+ between the observation group and the control group were statistically significant: (35.48 ± 5.64)% vs. (42.53 ± 6.17)%, (30.49 ± 4.72) ng/L vs. (35.64 ± 5.08) ng/L, (32.15 ± 3.06) ng/L vs. (35.33 ± 3.12) ng/L, (61.39 ± 3.28) % vs. (66.27 ± 3.05)%, (34.12 ± 1.93)% vs. (36.59 ± 2.61)%, 1.26 ± 0.34 vs. 1.52 ± 0.41, P<0.05. After treatment, the count of Th17 cells, Th17/Treg, interleukin-17 (IL-17) and γ-interferon (IFN-γ) in the observation group were higher than those in the control group:(8.69 ± 1.42)% vs. (7.94 ± 2.03)%, 0.24 ± 0.06 vs. 0.19 ± 0.05, (17.67 ± 3.11) ng/L vs. (12.18 ± 3.42) ng/L, (287.48 ± 45.12) ng/L vs. (254.27 ± 41.09) ng/L, P<0.05. During treatment, the difference in incidences of adverse reactions between the two groups had no statistically significant ( P>0.05). Conclusions:Oseltamivir combined with metformin can recover the balance of Th17/Treg cells in patients with T2DM and influenza A to a certain extent. Clinically, level of blood lactate should be monitored.
