摘要目的:探索二甲双胍联合克罗米芬用于治疗多囊卵巢综合征(PCOS)致不孕的临床效果。方法:2012年1月-2013年12月收治PCOS并不孕患者168例,随机分为试验组80例与对照组88例。试验组给予二甲双胍联合克罗米芬治疗,对照组给予克罗米芬治疗。比较两组用药前后雌激素、胰岛素的变化及排卵妊娠情况。结果:试验组与对照组经治疗后,FSH、LH、T、胰岛素较治疗前均有所改善,差异均有统计学意义(P<0.05),而且试验组各项指标改善情况均优于对照组(P<0.05)。试验组98个周期排卵率85.7%,妊娠率31.6%;对照组118个排卵周期排卵率69.5%,妊娠率20.3%。试验组的排卵率与妊娠率均高于对照组,差异具有统计学意义(P<0.05)。结论:二甲双胍联合克罗米芬治疗多囊卵巢综合征能提高排卵率和妊娠率。

AbstractObjective:To investigate the clinical effect of metformin combined with clomiphene in the treatment of polycystic ovary syndrome(PCOS).Methods:168 cases with PCOS and infertility were selected from January 2012 to December 2013.They were randomly divided into the experimental group with 80 cases and the control group with 88 cases.The experimental group were given metformin combined with clomiphene,while the control group were given clomiphene citrate.We compared the changes of estrogen,insulin and the situation of ovulation and pregnancy in two groups before and after the treatment.Results:After the treatment,the index of FSH,LH,T and Shima all improved both in two groups,and the differences were statistically significant(P<0.05).And The index improvement in the experimental group were more pronounced than in the control group(P<0.05).In the experimental group,the ovulation rate in 98 cycle was 85.7%,and the pregnancy rate was 31.6%.In the control group,the ovulation rate in 118 cycles was 69.5%,and the pregnancy rate was 20.3%.The ovulation rate and pregnancy rate in the experimental group were higher than that in the control group,and the difference was statistically significant(P<0.05).Conclusion:Metformin combined with clomiphene in treatment of polycystic ovary syndrome can improve the ovulation rate and pregnancy rate.

多囊卵巢综合征(polycystic ovarian syndrome,PCOS)是因为生殖内分泌和代谢功能紊乱引起的排卵障碍性疾病,在生育年龄妇女中的发病率5%~10%,在不排卵的不孕症患者中约占70%[1]。传统促排卵方法常使用克罗米芬(CC)进行治疗,但由于PCOS常伴有高胰岛素血症和胰岛素抵抗,二甲双胍作为胰岛素增敏剂,可增加对胰岛素的敏感性。本研究应用二甲双胍联合克罗米芬治疗多囊卵巢综合征所致不孕,探讨其临床疗效及安全性,现将结果汇报如下。
资料与方法
2012年1月-2013年12月收治PCOS患者168例,随机分为试验组80例(98周期)和对照组88例(118周期)。年龄23~38岁,BMI 23.3~27.8kg/m2,不孕年限2~8年,两组患者年龄、BMI、不孕年限等方面均无统计学差异,P>0.05,具有可比性。
纳入及排除标准:纳入标准:①临床表现:继发闭经、月经稀发、不孕、肥胖伴或不伴多毛症;②睾酮(T)水平≥2.7nmol/L或卵泡期黄体生成素(LH)/促卵泡激素(FSH)≥2;③B超监测:卵巢出现多囊性改变,单侧或双侧卵巢直径<9mm的小卵泡≥12个;④经子宫输卵管造影检查,证实一侧或者两侧的输卵管通畅;男方精液正常,并排除生殖系统器质性病变或其他不孕因素;⑤肝肾功能无异常,无过敏体质。排除标准:排除甲状腺疾病、高泌乳素血症、糖尿病、柯兴综合征等疾病;近3个月使用过激素类药物。
治疗方法:试验组给予二甲双胍联合克罗米芬治疗,对照组给予克罗米芬治疗。两组均于月经期2~4天抽取空腹静脉血,测定FSH、LH、T及胰岛素及血糖水平。对照组于月经第5天开始给予克罗米芬50mg/日,连续服用5天。停药后监测卵泡大小及子宫内膜厚度,同时给予补佳乐口服1mg/日。当卵泡直径≥18mm时,给予10 000U促绒毛膜性腺激素(HCG)肌注,36小时后监测是否排卵,如果监测到排卵,定期监测血中雌孕激素水平,给予黄体支持并指导同房。如果未监测到排卵后发生黄体化卵泡未破裂综合征(LUFS),则放弃本周期治疗。抽血后给予试验组二甲双胍0.5g/次,3次/日,连续服用3个月,于第4个月经期2~4天复查激素水平,第5天开始服用克罗米芬促进排卵,服用方法与后续治疗同对照组。
各种指标测量方法:FSH、LH、T及胰岛素采用化学发光法测定试剂盒的批间误差及批内误差均符合实验要求。
统计学方法:采用SPSS 19.0统计软件进行数据分析,计量资料采用x±s表示,组间比较采用t检验。计数资料采用χ2检验,等级资料采用秩和检验,检验水准α=0.05,P<0.05为差异有统计学意义。
结果
两组治疗前后各项指标的比较:试验组与对照组治疗后,FSH、LH、T、胰岛素较治疗前均有所改善,差异均有统计学意义(P<0.05),而且试验组各项指标改善情况均优于对照组(P<0.05),见表1。
两组排卵率、妊娠率比较:试验组98个周期排卵率85.7%,妊娠率31.6%;对照组118个排卵周期排卵率69.5%,妊娠率20.3%。试验组的排卵率与妊娠率均高于对照组,差异具有统计学意义(P<0.05)。见表2。
