Objective To investigate the association between serum soluble fms-like tyrosine kinase-1 (sFlt-1) and the choroidal structure during the pregnancy. Methods and analysis This prospective study enrolled 24 eyes of 12 consecutive healthy pregnant women. Each participant was evaluated during the first, second and third trimester of pregnancy and the postpartum period. The central choroidal thickness (CCT) and Choroidal Vascular Index (CVI) were measured using enhanced depth-imaging optical coherence tomography. Moreover, serum sFlt-1 and vascular endothelial growth factor (VEGF) concentrations were measured manually using ELISA. The association between choroidal structural parameters and serum sFlt-1/VEGF was analysed using a linear mixed model. Results The CCT was significantly thicker in the second and third trimester than the postpartum period (p<0.05). In contrast, there was no significant difference in the CVI throughout pregnancy or the postpartum period. Serum sFlt-1 levels were significantly higher during pregnancy than the postpartum period (p<0.05), whereas the serum VEGF levels were significantly lower during pregnancy than the postpartum period (p<0.05). Furthermore, serum sFlt-1 levels were significantly associated with CCT throughout pregnancy (p=0.011, linear mixed model). On the contrary, sFlt-1 levels was not associated with the CVI during the pregnancy. Conclusion Our results suggest that serum sFlt-1 might have an influence on the choroidal thickness during the pregnancy. Data are available on reasonable request.

妊娠期血清可溶性 fms 样酪氨酸激酶 1 与中央脉络膜厚度的关系:一项前瞻性研究

目的探讨妊娠期血清可溶性fms样酪氨酸激酶1(sFlt-1)与脉络膜结构的关系。方法与分析 这项前瞻性研究纳入了 12 名连续健康孕妇的 24 只眼睛。在怀孕的第一、第二和第三个三个月以及产后期间对每个参与者进行了评估。使用增强的深度成像光学相干断层扫描测量中央脉络膜厚度 (CCT) 和脉络膜血管指数 (CVI)。此外,使用ELISA手动测量血清sFlt-1和血管内皮生长因子(VEGF)浓度。使用线性混合模型分析脉络膜结构参数和血清 sFlt-1/VEGF 之间的关联。结果孕中期和孕晚期的CCT明显比产后更厚(p<0.05)。相比之下,在整个怀孕期间或产后期间,CVI 没有显着差异。妊娠期血清sFlt-1水平显着高于产后(p<0.05),而妊娠期血清VEGF水平显着低于产后(p<0.05)。此外,血清 sFlt-1 水平与整个孕期的 CCT 显着相关(p=0.011,线性混合模型)。相反,sFlt-1 水平与怀孕期间的 CVI 无关。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。在整个怀孕期间或产后期间,CVI 没有显着差异。妊娠期血清sFlt-1水平显着高于产后(p<0.05),而妊娠期血清VEGF水平显着低于产后(p<0.05)。此外,血清 sFlt-1 水平与整个孕期的 CCT 显着相关(p=0.011,线性混合模型)。相反,sFlt-1 水平与怀孕期间的 CVI 无关。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。在整个怀孕期间或产后期间,CVI 没有显着差异。妊娠期血清sFlt-1水平显着高于产后(p<0.05),而妊娠期血清VEGF水平显着低于产后(p<0.05)。此外,血清 sFlt-1 水平与整个孕期的 CCT 显着相关(p=0.011,线性混合模型)。相反,sFlt-1 水平与怀孕期间的 CVI 无关。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。而妊娠期血清VEGF水平显着低于产后(p<0.05)。此外,血清 sFlt-1 水平与整个孕期的 CCT 显着相关(p=0.011,线性混合模型)。相反,sFlt-1 水平与怀孕期间的 CVI 无关。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。而妊娠期血清VEGF水平显着低于产后(p<0.05)。此外,血清 sFlt-1 水平与整个孕期的 CCT 显着相关(p=0.011,线性混合模型)。相反,sFlt-1 水平与怀孕期间的 CVI 无关。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。结论 我们的研究结果表明,血清 sFlt-1 可能对妊娠期脉络膜厚度有影响。可根据合理要求提供数据。
