Objective. This study aimed at analyzing the association between recurrent pregnancy loss (RPL) and factor V G1691A (FVL), prothrombin G20210 (FII); and MTHFR C677T (MTHFR) in Palestinian women. Method. We studied 329 Palestinian women with RPL and/or stillbirth (SB); and compared them to 402 healthy reproductive Palestinian women. Cases and controls were tested for the above mutations. Odds ratio (OR) at confidence interval (CI) of 95% was used as a measure of association between the mutations and RPL. Results. Our statistical analysis showed a slightly increased association, which was not significant between FVL and RPL (OR 1.32, 95% CI 0.90-1.94), and no association between FII (OR 0.84, 95% CI 0.38-1.92), MTHFR (OR 0.58, 95% CI 0.32-1.03), and RPL. Further analysis of RPL subgroups revealed an association between FVL and first-trimester loss (OR 1.33, 95% CI 0.892-1.989), and second-trimester loss (OR 1.13, 95% CI 0.480-2.426), both were not statistically significant. Furthermore, the only statistically significant association was between FVL and SB (OR 2.0, 95% CI 1.05-3.70). Conclusion. Our analysis had failed to find a significant association between FVL, FII, MTHFR; and RPL in either the first or second trimester. FVL was significantly associated with fetal loss if the loss was a stillbirth.
目的。本研究旨在分析巴勒斯坦女性复发性流产(RPL)与凝血因子V G1691A(FVL)、凝血酶原G20210(FII)以及亚甲基四氢叶酸还原酶C677T(MTHFR)之间的关联。方法。我们研究了329名有复发性流产和/或死产(SB)的巴勒斯坦女性,并将她们与402名生殖健康的巴勒斯坦女性进行比较。对病例组和对照组进行上述突变检测。采用95%置信区间(CI)的比值比(OR)作为衡量突变与复发性流产之间关联的指标。结果。我们的统计分析显示,FVL与复发性流产之间的关联略有增加,但不显著(OR = 1.32,95% CI = 0.90 - 1.94),FII(OR = 0.84,95% CI = 0.38 - 1.92)、MTHFR(OR = 0.58,95% CI = 0.32 - 1.03)与复发性流产之间无关联。对复发性流产亚组的进一步分析显示,FVL与孕早期流产(OR = 1.33,95% CI = 0.892 - 1.989)以及孕中期流产(OR = 1.13,95% CI = 0.480 - 2.426)之间存在关联,但两者均无统计学意义。此外,唯一具有统计学意义的关联是FVL与死产之间的关联(OR = 2.0,95% CI = 1.05 - 3.70)。结论。我们的分析未能发现FVL、FII、MTHFR与孕早期或孕中期复发性流产之间存在显著关联。如果流产为死产,则FVL与胎儿丢失显著相关。
