Abstract
Background: Gestational diabetes mellitus (GDM) has recently been associated with abnormal profiles of inflammatory cells and cytokines, though the findings remain inconsistent and unclear.
Aim: To elucidate the peripheral immune status in GDM.
Methods: We systematically screened databases including Web of Science, PubMed, and EMBASE for eligible studies. Original articles reporting different immune cell levels in GDM compared to normal glucose-tolerance pregnant women were included to extract usable data. The pooled mean difference (MD) with 95% confidence interval (CI) was analyzed as the outcome measure. The Newcastle-Ottawa scale was employed to assess study quality.
Results: A total of 19 studies involving various immune cell subgroups were included in our analysis. Specifically, total CD4+ T cells (WMD = 3.08; 95%CI: 0.81-5.35) were significantly increased in GDM groups. In contrast, total lymphocytes (SMD = 0.05; 95%CI: -0.16 to 0.26), CD3+ T cells (SMD = -0.34; 95%CI: -1.01 to 0.32), CD8+ T cells (SMD = 0.21; 95%CI: -0.31 to 0.73), and natural killer T (NKT) Cells (SMD = 0.83; 95%CI: -1.10 to 2.75) showed no significant changes in GDM. Activation markers (HLA-DR+ or CD69+) on CD4+ T cells (WMD = 0.20; 95%CI: 0.06-0.34) were increased in GDM patients. Treg cells, a classical subgroup of CD4+ T cells, showed a decreasing trend in GDM compared to controls (SMD = -0.83; 95%CI: -1.31 to -0.34). These results indicate an abnormal immune status in the peripheral profiles of GDM.
Conclusion: GDM may not only be a dysglycemia-related condition but also an immune disorder characterized by abnormal peripheral immune profiles, including higher levels of CD4+ T cells and a reduced population of Treg cells. Treating immune dysregulation could be a new direction for GDM management, although further research is needed to understand the precise mechanisms of immune overactivation in GDM.
期刊介绍:
The WJD is a high-quality, peer reviewed, open-access journal. The primary task of WJD is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of diabetes. In order to promote productive academic communication, the peer review process for the WJD is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJD are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in diabetes. Scope: Diabetes Complications, Experimental Diabetes Mellitus, Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, Diabetes, Gestational, Diabetic Angiopathies, Diabetic Cardiomyopathies, Diabetic Coma, Diabetic Ketoacidosis, Diabetic Nephropathies, Diabetic Neuropathies, Donohue Syndrome, Fetal Macrosomia, and Prediabetic State.
