The Role of IL-6 and TNF-α as Early Biomarkers in the Prediction and Diagnosis of Gestational Diabetes Mellitus
Gestational diabetes mellitus (GDM) occurs in approximately 9–25% of pregnancies and, if left undiagnosed or inadequately controlled, can lead to adverse outcomes for both the mother and the fetus, short and long term.

| Summary: | Gestational diabetes mellitus (GDM) occurs in approximately 9–25% of pregnancies and, if left undiagnosed or inadequately controlled, can lead to adverse outcomes for both the mother and the fetus, short and long term. GDM is characterized by glucose intolerance with onset or first recognition during pregnancy and is a multifactorial condition with a pathophysiology that remains incompletely understood. It is strongly associated with a chronic low-grade inflammatory state that contributes to insulin resistance, a hallmark of GDM pathogenesis. Among the fundamental pro-inflammatory cytokines implicated in this process, TNF-α and IL-6 play central roles. TNF-α is a cytokine primarily secreted by activated macrophages, as well as by adipocytes in the context of obesity. Many studies have shown that its levels are elevated in pregnant women with GDM compared to normoglycemic pregnant individuals. IL-6 is another pro-inflammatory cytokine secreted by immune cells, adipose tissue, and the placenta. It is found in higher concentrations in the maternal circulation during pregnancies complicated by GDM. Both TNF-α and IL-6 act synergistically to perpetuate a pro-inflammatory intrauterine environment. Their combined effects exacerbate insulin resistance and may impair pancreatic β-cell compensation during pregnancy, facilitating the onset of GDM in genetically or metabolically susceptible individuals. Recent research has identified various maternal serum biomarkers, such as TNF-α and IL-6, that may hold promise for the early detection of GDM. The aim of our study is to evaluate whether TNF-α and IL-6 can be used as diagnostic tools for the early diagnosis of GDM, allowing for timely intervention and reducing the risk of associated maternal and fetal complications. |
