Considering potential roles of soluble receptor for advanced glycation end products (sRAGE) and placental growth factor (PlGF) in ovarian function and embryo implantation, in the present study we have evaluated the association of these factors and also PlGF/sFlt-1 ratio with the ovarian response and implantation rate by dividing patients according to the OSI.
In a cross-sectional study, 90 infertile women who were undergoing ICSI cycle using long protocol were recruited. The patients were divided according to ovarian sensitivity index (OSI). ICSI cycle outcomes were evaluated for each patient and PlGF, sFlt-1 and sRAGE levels of follicular fluid were assayed using commercial ELISA kits.
Follicular fluid (FF) sRAGE levels and PlGF/sFlt-1 ratio were statistically greater in high-responder women than other responders (p < 0.05). Positive correlations were obtained between sRAGE level with the number of oocytes, follicles and OSI level. sRAGE levels with cutoff value of 4.83 (ng/ml) for evaluating the pregnancy outcome showed 81.8 % sensitivity and 60.7 % specificity. Furthermore, there were positive associations between PlGF/sFlt-1 ratio with the number of oocytes, embryos and OSI level.
In conclusion, the results of current study supported that good ovarian response is independent of pregnancy outcome. Our results showed that FF levels of sRAGE and PlGF/sFlt-1 ratio could be used as markers for determining the high-responder women. Also, FF sRAGE levels could be a good predictor for ART outcome.
鉴于晚期糖基化终产物可溶性受体(sRAGE)和胎盘生长因子(PlGF)在卵巢功能及胚胎着床中的潜在作用,在本研究中,我们通过根据卵巢敏感性指数(OSI)对患者进行分组,评估了这些因子以及PlGF/sFlt-1比值与卵巢反应和着床率之间的关联。
在一项横断面研究中,招募了90名采用长方案进行卵胞浆内单精子注射(ICSI)周期的不孕女性。根据卵巢敏感性指数(OSI)对患者进行分组。评估每位患者的ICSI周期结局,并使用商用酶联免疫吸附测定(ELISA)试剂盒检测卵泡液中PlGF、sFlt-1和sRAGE的水平。
高反应性女性卵泡液(FF)中的sRAGE水平和PlGF/sFlt-1比值在统计学上高于其他反应者(p < 0.05)。sRAGE水平与卵母细胞数量、卵泡数量及OSI水平之间呈正相关。以4.83(ng/ml)为临界值的sRAGE水平用于评估妊娠结局时,敏感性为81.8%,特异性为60.7%。此外,PlGF/sFlt-1比值与卵母细胞数量、胚胎数量及OSI水平之间也呈正相关。
总之,本研究结果支持良好的卵巢反应与妊娠结局无关。我们的结果表明,卵泡液中sRAGE水平和PlGF/sFlt-1比值可作为确定高反应性女性的标志物。此外,卵泡液sRAGE水平可能是辅助生殖技术(ART)结局的良好预测指标。
