JCEM:月经周期或可预测PCOS患者的胰岛素抵抗

该研究是一项横断面研究,在医学院附属三级医疗中心进行。受试者为494例通过鹿特丹标准诊断为PCOS的女性和138例月经正常、无多毛的对照组女性。干预措施包括病史、体格检查和采血。主要评价指标包括身体评估,以及总睾酮(TT)、游离睾酮(FT)、脱氢表雄酮(DHEAS)、空腹血糖和胰岛素水平,并计算稳态模型评估的胰岛素抵抗指数(HOMA-IR)。

该研究结果表明,总的来说,80%的PCOS受试者伴有临床明显的月经稀少。剩余的受试者显示阴道出血间隔<35天(月经频繁或临床月经正常)。研究中仅有10%PCOS受试者排卵。校正BMI、年龄和种族后,所有PCOS受试者月经周期大于35天,平均HOMA-IR水平显著高于对照组,而且,月经周期大于3个月的受试者有最高的HOMA-IR水平。规律阴道出血的PCOS受试者与对照组相比,平均HOMA-IR水平没有差异,不论他们有无排卵,或者他们的月经周期是否小于26天。

该研究发现,月经稀少的PCOS女性(包括临床见到的绝大多数PCOS患者)比对照组有明显更高的胰岛素抵抗。大约20%阴道出血间隔时间小于35天的PCOS女性没有明显的胰岛素抵抗,不论她们有无排卵。总的来说,PCOS女性临床上明显月经紊乱的出现可被用来预测胰岛素抵抗的存在和,以及胰岛素抵抗可能的程度。

Clin Sci :早餐吃好能护卵巢

不少办公室女性的早餐都很单调,甚至草草了事。可发表在最新一期《临床科学》杂志上的一项研究提醒,丰富的早餐可以保护卵巢,提高生育力。 以色列特拉维夫大学的研究人员发现,很多卵巢功能异常的女性存在“胰岛素抵抗”,最终导致体内睾丸激素偏高,降低了生育机会。进一步试验发现,无论是患有多囊卵巢综合征(PCOS)的女性还是健康女性,在每天同样摄入1800卡总热量的情况下,与“早餐凑合、晚餐大补”(早

代谢缺乏灵活性,也就是机体在胰岛素刺激条件下,脂肪氧化向碳水化合物氧化转变的功能受损,与胰岛素抵抗有关。这种代谢可塑性的改变可以导致器官功能障碍,并被认为是代谢综合征异常中的关键问题。在多囊卵巢综合症(PCOS)的女性是否发生这种现象仍不清楚。为了验证代谢缺乏灵活性是否是PCOS女性患者的一个特征,以及雄激素过多症是否可以导致这种现象,来自意大利维罗纳大学医学院的Paolo Moghetti教授及
