To investigate whether active leukocyte immunization increases levels of anticardiolipin antibodies in women with recurrent spontaneous abortions. To assess the impact of anticardiolipin antibodies on pregnancy outcome in these women.
Patients who had received various treatments in an ongoing randomized trial were studied prospectively.
A department of clinical immunology investigating women with recurrent spontaneous abortions from all over Denmark.
Eighty-nine patients with unexplained recurrent spontaneous abortions whose pregnancies had been completed during the course of the trial.
After randomization, 44 patients were actively immunized with husband's or third party leukocytes, and 27 patients received placebo. Eighteen patients received anticoagulation therapy in pregnancy.
Changes in levels of immunoglobulin (Ig)M class and IgG class anticardiolipin antibodies after active immunization. Frequency of new miscarriages in patients who were positive or negative for anticardiolipin antibodies.
Neither IgM nor IgG anticardiolipin antibodies changed significantly after active immunization (P greater than 0.2). The interim results of the immunization trial showed a success rate of 68% in the treated group versus 56% in the placebo group (not significantly different). Relative risk of miscarriage in anticardiolipin antibody-positive patients compared with anticardiolipin antibody-negative patients was 1.3 (95% confidence interval 0.7 to 2.2; P = 0.4) in the combined study groups.
Patients eligible for active immunization did not exhibit significant changes in anticardiolipin antibody levels subsequent to the treatment. The treatment did not seem to provide any overall benefit with respect to pregnancy outcome. Prospectively, the risk of miscarriage in patients positive for anticardiolipin antibodies was not significantly increased.
研究主动白细胞免疫是否会增加复发性自然流产女性体内抗心磷脂抗体的水平。评估抗心磷脂抗体对这些女性妊娠结局的影响。
对正在进行的一项随机试验中接受了各种治疗的患者进行前瞻性研究。
丹麦一个临床免疫科,该科室对来自丹麦各地的复发性自然流产女性进行研究。
89例原因不明的复发性自然流产患者,其妊娠在试验过程中已结束。
随机分组后,44例患者接受丈夫或第三方白细胞的主动免疫,27例患者接受安慰剂治疗。18例患者在孕期接受抗凝治疗。
主动免疫后免疫球蛋白(Ig)M类和IgG类抗心磷脂抗体水平的变化。抗心磷脂抗体阳性或阴性患者再次流产的频率。
主动免疫后,IgM和IgG抗心磷脂抗体均未发生显著变化(P>0.2)。免疫试验的中期结果显示,治疗组成功率为68%,安慰剂组为56%(无显著差异)。在合并研究组中,抗心磷脂抗体阳性患者与抗心磷脂抗体阴性患者相比,流产的相对风险为1.3(95%置信区间0.7至2.2;P=0.4)。
符合主动免疫条件的患者在治疗后抗心磷脂抗体水平未出现显著变化。该治疗在妊娠结局方面似乎未带来任何总体益处。前瞻性来看,抗心磷脂抗体阳性患者流产的风险未显著增加。
