Gestational diabetes mellitus (GDM) represents a significant metabolic disorder that affects pregnant women worldwide and has negative consequences for both the mother and her offspring. This research aims to investigate the relation between circulating levels of Galectin-3 and the incidence of GDM, and to evaluate its potential as a biomarker for monitoring and early detection of the disease.
Methods
A thorough search of the literature has been performed using databases such as Scopus, Web of science, Embase, Cochrane Library and PubMed. The standardized mean difference (SMD) and corresponding confidence intervals (CIs) were used to compute the effect size from individual records and pooled using the Random-effect model.
Results
Our meta-analysis synthesized data from 9 studies, encompassing 1,286 participants (533 GDM patients and 753 healthy pregnant controls). The findings demonstrated a considerable increase in Galectin-3 levels among individuals diagnosed with GDM as compared to the healthy control (SMD = 0.929; CI: 0.179–1.679; p = 0.015), with observed heterogeneity (I2 = 87%; p < 0.001). Subgroup analyses revealed the influence of factors such as age, BMI, study design, and sample type on Galectin-3 levels. A meta-regression analysis further identified trends indicating that levels of Galectin-3 are linked to gestational age, specific geographical areas, and sample size.
Conclusion
Increased levels of Galectin-3 exhibit a significant association with GDM, indicating its prospective utility as a biomarker for early detection and risk assessment. Further research is warranted to elucidate its regulation and clinical implications in GDM management.
