Objective: To investigate maternal serum galectin-1 and galectin-3 levels in pregnancies complicated with preterm prelabor rupture of membranes (PPROM) and to compare with pregnancies delivered at term.Materials and methods: In this cross-sectional study, 40 women with singleton pregnancies complicated with PPROM between 24 and 34 weeks of gestation were compared with gestational age-matched 40 pregnant women with no obstetrics complications, who delivered at term. The maternal serum galectin-1 and galectin-3 levels were measured.Results: Patients complicated with PPROM had significantly higher levels of galectin-1 (p = .001) and galectin-3 (p = .003) than the control group. Maternal serum galectin-3 levels were found significantly negatively correlated with the gestational age at delivery and birth weight.Conclusion: Maternal serum galectin-1 and galectin-3 levels were significantly higher in pregnancies complicated with PPROM. Galectin-1 and galectin-3, with their regulatory effects in key biological processes, may be both an initiating factor in the pathophysiology of PPROM, a marker in the prediction, and a target of preventing strategies of PPROM.
