Benign Prostate Hyperplasia (BPH) is a common health problem in aging male. Free radicals and Reactive Oxygen Species (ROS) are produced in overwhelming quantity with advancement of age. When in oxidative stress, these reactive species cause extensive damage to various organ in the body, may be associated with pathogenesis of BPH also. This study aimed at assessing Malondialdehyde (MDA), the marker of lipid peroxidation and anti-oxidants e.g. alpha-Tocopherol and Ascorbate status in plasma in BPH patients. Forty eight (n=48) cases of BPH and forty six (n = 46) healthy age matched controls were enrolled. Plasma MDA level showed 4.81+/-1.87 nmol/ml in cases compared to 3.69+/-1.56 nmol/ml in healthy controls (p<0.001). There were significant decrease in plasma alpha-Tocopherol and ascorbate level which were 0.85+/-0.12 mg/dl and 0.93 +/- 0.13 mg/dl in cases compared to 1.37+/-0.31 mg/dl and 1.44+/-0.38 mg/dl in healthy controls respectively. Inverse correlation of plasma MDA with alpha-Tocopherol (r = -0.09, p>0.05) and Ascorbate (r =-0.51, p=0.008) was found in BPH patients. There was mild elevation of PSA in BPH patients compared with control but was not statistically significant. Thus, our study showed the evidence of association of oxidative stress in BPH patients.
良性前列腺增生(BPH)是老年男性常见的健康问题。随着年龄的增长,自由基和活性氧(ROS)大量产生。在氧化应激状态下,这些活性物质会对身体的各个器官造成广泛损害,这可能也与BPH的发病机制有关。本研究旨在评估BPH患者血浆中脂质过氧化标志物丙二醛(MDA)以及抗氧化剂如α-生育酚和抗坏血酸的状态。纳入了48例BPH患者(n = 48)和46例年龄匹配的健康对照者(n = 46)。BPH患者血浆MDA水平为4.81±1.87 nmol/ml,而健康对照者为3.69±1.56 nmol/ml(p<0.001)。BPH患者血浆α-生育酚和抗坏血酸水平显著降低,分别为0.85±0.12 mg/dl和0.93±0.13 mg/dl,而健康对照者分别为1.37±0.31 mg/dl和1.44±0.38 mg/dl。在BPH患者中,发现血浆MDA与α-生育酚(r = -0.09,p>0.05)和抗坏血酸(r = -0.51,p = 0.008)呈负相关。与对照组相比,BPH患者的前列腺特异性抗原(PSA)有轻度升高,但无统计学意义。因此,我们的研究显示了BPH患者存在氧化应激关联的证据。
