摘要
Background: This study aimed to evaluate the umbilical cord blood chondroitin sulfate proteoglycan 4 (CSPG4) concentrations in pregnancies complicated with fetal growth restriction (FGR) and aimed to investigate the relationship between the CSPG4 levels in these pregnancies and adverse neonatal outcomes. Methods: This prospective case-control study was conducted between August 2023 and January 2024. The study included 80 singleton pregnancies at 35 to 39 weeks of gestation. Among these, 40 were diagnosed with FGR and 40 served as the control group. After the delivery, samples of the cord blood were collected prior to the placental delivery. Results: The CSPG4 levels were significantly higher in the study group (FGR), 1,153 (1,059- 1,261) pg/mL, than in the control group, 1,107 (873- 1,197) pg/mL (p = 0.024). When all patients were evaluated, the CSPG4 levels showed a positive correlation with the systolic/diastolic (S/D) ratio of the umbilical arteries (r = 0.276, p = 0.013). A statistically significant negative correlation was observed between the levels of CSPG4 in the umbilical cord blood and the Apgar scores at the 1st (r =-0.256, p = 0.022) and 5th (r =-0.250, p = 0.026) minutes. The discriminatory power of the umbilical cord CSPG4 level in the determination of composite adverse neonatal outcomes was evaluated by ROC analysis and a cutoff point of > 1,091.25 pg/mL, showing a sensitivity of 93.3%, a specificity of 46.2%, and an AUC of 0.661 (95% CI: 0.547- 0.763, p = 0.019). Conclusions: Elevated levels of CSPG4 have been observed in the umbilical cord blood in pregnancies complicated by FGR; higher levels are associated with adverse neonatal outcomes.
