The current study was initiated to determine the prevalence of activated protein C (APC) resistance, factor V Leiden and antiphospholipid antibodies (APA) in Iraqi women with recurrent fetal loss (RFL), and evaluate the outcome of intervention in those with such states. For this purpose a total of 103 Iraqi women referred to a major teaching hospital in Northern Iraq with two or more consecutive fetal losses, as well as 100 age matched women with no history of fetal loss and at least one live birth were enrolled. After appropriate clinical evaluation, the enrolled subjects were tested for APA as well as APC resistance. Subjects who were APC resistant were further tested for factor V Leiden mutation using a polymerase chain reaction and reverse hybridization. Patients with documented APA and/or with APC resistance, were put on low dose aspirin with or without low molecular weight heparin during pregnancy, and followed for a minimum of 5 years. The results revealed that among patients' group, APA were detected in 19.4 % compared to 1.0 % of the controls (OR 23.9, p = 0.00005). On the other hand, APC resistance was documented in 9.7 % compared to 1.0 % of the controls (OR 10.6, p = 0.01). Factor V Leiden was detected in 3.9 % of patients and 1 % of the controls (p = 0.38). Among 17 patients with APA available for follow up, there were 24 pregnancies, 18 of which ended with live births (75 %). While among the ten patients who had factor V Leiden or were APC resistant non-carriers, there were 13 pregnancies, 12 ended with live births (92.3 %). In conclusion, this study has demonstrated that among the enrolled Iraqi women, APA and APCR and not factor V Leiden were significantly associated with RFL, and that treatment with aspirin (with or without low molecular weight heparin) had lead to live births in 80.6 % of pregnancies.
开展本研究旨在确定伊拉克反复自然流产(RFL)女性中活化蛋白C(APC)抵抗、凝血因子V莱顿突变及抗磷脂抗体(APA)的患病率,并评估存在上述情况的女性接受干预后的结局。为此,共有103名转诊至伊拉克北部一家大型教学医院的有两次或更多次连续自然流产的伊拉克女性,以及100名年龄匹配、无自然流产史且至少有一次活产的女性纳入研究。经过适当的临床评估后,对纳入的受试者进行了APA及APC抵抗检测。对存在APC抵抗的受试者,使用聚合酶链反应和反向杂交进一步检测凝血因子V莱顿突变。记录有APA和/或存在APC抵抗的患者在孕期服用低剂量阿司匹林,加用或不加用低分子量肝素,并至少随访5年。结果显示,患者组中检测到APA的比例为19.4%,而对照组为1.0%(比值比23.9,p = 0.00005)。另一方面,记录到存在APC抵抗的比例为9.7%,而对照组为1.0%(比值比10.6,p = 0.01)。凝血因子V莱顿突变在3.9%的患者及1%的对照组中被检测到(p = 0.38)。在17名可进行随访的APA患者中,共有24次妊娠,其中18次以活产告终(75%)。而在有凝血因子V莱顿突变或存在APC抵抗的非携带者的10名患者中,共有13次妊娠,12次以活产告终(92.3%)。总之,本研究表明,在纳入的伊拉克女性中,与RFL显著相关的是APA和APC抵抗而非凝血因子V莱顿突变,并且阿司匹林(加用或不加用低分子量肝素)治疗使80.6%的妊娠获得活产结局。
