The aim of this study is to evaluate the diagnostic value of serum oxidative stress marker levels (ischemia-modified albumin, IMA; malondialdehyde, MDA) and total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) levels that occur in ovarian torsion and to determine the threshold value of these markers in the diagnosis of ovarian torsion.
In this prospective case-control study, 34 women (the study group) with acute pelvic pain (20 with and 14 without ovarian torsion) and 40 control subjects were included. The diagnosis of ovarian torsion was confirmed with laparoscopy in all cases. Preoperative serum samples were collected in the study group. Serum oxidative stress marker levels (IMA and MDA) and TOS, TAS and OSI levels were measured.
Serum MDA, TOS and IMA concentrations were significantly higher in women with ovarian torsion than in the healthy control group. However, serum TAS, TOS and OSI concentrations were significantly higher in women without ovarian torsion than within the healthy control group. Only IMA significantly distinguished patients with or without ovarian torsion. The best IMA value, according to the receiver operating characteristic curve, was 0.7045 absorbance units, with 90.00% sensitivity and 92.31% specificity. The patients in the ovarian torsion group had significantly lower serum TAS and OSI levels compared with patients without ovarian torsion.
The elevated serum IMA levels with high sensitivity-specificity values observed in women with ovarian torsion seem to have a potential role as a serum marker in the preoperative diagnosis of ovarian torsion in emergency settings.
本研究旨在评估血清氧化应激标志物水平(缺血修饰白蛋白,IMA;丙二醛,MDA)以及总氧化剂状态(TOS)、总抗氧化剂状态(TAS)和氧化应激指数(OSI)水平在卵巢扭转中的诊断价值,并确定这些标志物在卵巢扭转诊断中的阈值。
在这项前瞻性病例对照研究中,纳入了34名患有急性盆腔疼痛的女性(研究组,其中20例有卵巢扭转,14例无卵巢扭转)以及40名对照受试者。所有病例均通过腹腔镜检查确诊卵巢扭转。研究组在术前采集血清样本,检测血清氧化应激标志物水平(IMA和MDA)以及TOS、TAS和OSI水平。
卵巢扭转女性的血清MDA、TOS和IMA浓度显著高于健康对照组。然而,无卵巢扭转女性的血清TAS、TOS和OSI浓度显著高于健康对照组。只有IMA能够显著区分有无卵巢扭转的患者。根据受试者工作特征曲线,IMA的最佳值为0.7045吸光度单位,灵敏度为90.00%,特异性为92.31%。与无卵巢扭转的患者相比,卵巢扭转组患者的血清TAS和OSI水平显著更低。
在卵巢扭转女性中观察到的血清IMA水平升高且具有高灵敏度 - 特异性值,似乎在急诊情况下卵巢扭转的术前诊断中具有作为血清标志物的潜在作用。
