In this study, our objective was to explore the association between gestational diabetes mellitus (GDM) and second trimester maternal plasma levels of lipoxin A4 (LXA4), along with proinflammatory markers such as interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-α), and the anti-angiogenic factor vascular endothelial growth factor receptor 1 (VEGFR-1) in pregnant women. The study included a cohort of 30 pregnant women with GDM and a control group of 30 normoglycaemic pregnant women matched for age, body mass index, and gestational age. Plasma samples were collected and analysed by enzyme-linked immunosorbent assay to assess specific biomarkers. The GDM group had significantly lower levels of LXA4 and higher levels of TNF-α and VEGFR-1 compared to the control group (p = 0.038, p = 0.025, and p = 0.002, respectively). A statistically significant decrease in the LXA4/TNF-α ratio was observed in the GDM group (p = 0.004). The results suggest that each unit decrease in the LXA4/TNF-α ratio is associated with a 1.280-fold increase in the risk of GDM. These findings suggest a potential diagnostic role for the LXA4/TNFα ratio as a marker for women with GDM. This work provides new insights into the pathogenesis of GDM and highlights the important interplay between inflammation and metabolic dysregulation.
