摘要

目的

探讨甲氨蝶呤（MTX）注射液联合米非司酮片治疗异位妊娠的效果。

方法

采用回顾性队列研究方法，收集2013年1月1日－2021年12月31日在成都大学附属医院就诊的异位妊娠患者资料。单独给予MTX注射液的为对照组，给予MTX注射液联合米非司酮片的为暴露组。采用倾向性评分匹配（PSM）法均衡两组基线变量，比较匹配后队列的结局指标。

结果

纳入125例患者，其中对照组68例，暴露组57例。经PSM后，各组有46例匹配成功。暴露组和对照组的治疗有效率分别为73.91%和63.04%、药品不良反应（ADR）发生率分别为21.74%和13.04%，均无显著差异（

＞0.05）。两组患者组内治疗前后血清

-HCG值对比均显著下降（

＜0.05），但两组患者治疗后血清

-HCG值及其恢复正常的

时间、再次妊娠、再次异位妊娠、再次宫内妊娠的间隔时间均无显著差异（

＞0.05）。暴露组的B超妊娠包块平均直径治疗前后差值、临床症状缓解时间和住院时间均显著大于对照组（

＜0.05），但住院期间的药品费用和住院总费用并未显著增加（

＞0.05）。MTX单剂方案组和多剂方案组的治疗有效率、ADR发生率无显著差异（

＞0.05），单剂方案组的住院时间、药品费用、住院总费用均显著少于多剂方案组（

＜0.05）。

结论

MTX注射液联合或不联合米非司酮片都能有效治疗异位妊娠，有效性和安全性相当。联合治疗可以促进包块缩小，且对住院费用和再次妊娠情况无明显影响。MTX单剂方案和多剂方案治疗效果相当，但多剂方案增加了住院时间和住院费用。

Abstract

OBJECTIVE

To investigate the efficacy of Methotrexate （MTX） injection combined with Mifepristone tablets in the treatment of ectopic pregnancy.

METHODS

A retrospective cohort study method was used to collect data on patients with ectopic pregnancy who visited the Affiliated Hospital of Chengdu University from January 1， 2013 to December 31， 2021. Control group was given MTX injection alone， and exposure group was given MTX injection combined with Mifepristone tablets. Baseline variables were balanced between the two groups using a propensity score matching （PSM）， and the outcomes of the matched cohorts were compared.

RESULTS

A total of 125 patients were included， involving 68 in the control group and 57 in the exposure group. After PSM， 46 cases in each group were successfully matched. There was no significant difference in the treatment response rate and the incidence of adverse drug reaction （ADR） between the exposure group and the control group， which were 73.91% and 63.04%， 21.74% and 13.04% （

＞0.05）. Compared with before treatment， serum levels of

-HCG were all significantly decreased in 2 groups after treatment （

＜0.05）； there was no significant difference in the serum level of

-HCG after treatment， the time to return to normal， the interval time of second pregnancy， second ectopic pregnancy and second intrauterine pregnancy between 2 groups （

＞0.05）. The mean diameter difference of B-ultrasound pregnancy mass before and after treatment， duration of clinical symptom remission and length of hospital stay in the exposure group were significantly higher than those in the control group （

＜0.05）， but drug costs during hospitalization and total hospitalization costs were not significantly increased （

＞0.05）. There were no significant difference between single-dose group and multi-dose group of MTX in the treatment response rate and the incidence of ADR （

＞0.05）. The hospitalization time， drug cost and total cost of the single dose group were significantly less than those of the multi-dose group （

＜0.05）.

CONCLUSIONS

MTX injection combined with or without Mifepristone tablet can both effectively treat ectopic pregnancy， with comparable efficacy and safety. MTX single-dose regimen is similar to the multi-dose regimen in efficacy， but the multi-dose regimen increases the hospital stay and hospitalization costs.
