Polycystic ovarian syndrome (PCOS) is one of the most common endocrine diseases of women. Oxidative stress is an important component of the cardio-metabolic risk seen in these women. Oxidative stress has been reported in obese PCOS women. This study is taken up to study oxidative stress in non-obese PCOS women.
Twenty five non-obese women with PCOS attending the Endocrinology outpatient Department of Sri Venkateswara Institute of Medical Sciences, Tirupati, India along with 25 healthy BMI matched controls were included in the study. The changes in the lipid peroxidation products (MDA), and total anti oxidant capacity (FRAP) as an index of anti oxidant status along with fasting glucose, insulin and uric acid levels were measured in both groups. Insulin resistance was evaluated by using homeostasis model assessment for insulin resistance [HOMA-IR)= [FPG (mg/dl) × insulin (mIU/L)]/ 405] in both groups.
Serum MDA and uric acid levels were increased in the study group compared with controls and FRAP levels were decreased in the study group compared to controls though statistically insignificant.
Oxidative stress is also present in non-obese women with PCOS. Oxidative stress further increases the CVD risk in these women.Correcting oxidative stress with antioxidants along with monitoring the antioxidant status using a simple assay like FRAP could have a beneficial effect on oxidative stress induced insulin resistance and hyperandrogenism seen in these women.
多囊卵巢综合征(PCOS)是女性最常见的内分泌疾病之一。氧化应激是这些女性心血管代谢风险的重要组成部分。肥胖的PCOS女性中已报道存在氧化应激。本研究旨在探讨非肥胖PCOS女性的氧化应激情况。
印度蒂鲁伯蒂市斯里文卡特斯瓦拉医学科学研究所内分泌科门诊的25名非肥胖PCOS女性以及25名体重指数(BMI)匹配的健康对照者纳入本研究。测量两组的脂质过氧化产物(MDA)变化、作为抗氧化状态指标的总抗氧化能力(FRAP)以及空腹血糖、胰岛素和尿酸水平。两组均采用胰岛素抵抗稳态模型评估法[HOMA-IR =(空腹血糖(mg/dl)×胰岛素(mIU/L))/405]评估胰岛素抵抗。
与对照组相比,研究组血清MDA和尿酸水平升高,研究组FRAP水平降低,尽管差异无统计学意义。
非肥胖PCOS女性也存在氧化应激。氧化应激进一步增加了这些女性患心血管疾病的风险。使用抗氧化剂纠正氧化应激并通过如FRAP这样的简单检测方法监测抗氧化状态,可能对这些女性因氧化应激引起的胰岛素抵抗和高雄激素血症产生有益影响。
