Oxidative stress in patients with benign prostate hyperplasia

Area of Science:

• Urology
• Biochemistry
• Oxidative Stress Research

Background:

• Benign Prostate Hyperplasia (BPH) is a prevalent condition in aging males.
• Aging increases the production of free radicals and Reactive Oxygen Species (ROS).
• Oxidative stress from ROS may contribute to the pathogenesis of BPH.

Purpose of the Study:

• To assess Malondialdehyde (MDA), a lipid peroxidation marker, and antioxidant status (alpha-Tocopherol, Ascorbate) in BPH patients.
• To investigate the association between oxidative stress markers and BPH.
• To evaluate Prostate-Specific Antigen (PSA) levels in BPH patients.

Main Methods:

• Plasma MDA, alpha-Tocopherol, and Ascorbate levels were measured in 48 BPH patients and 46 age-matched healthy controls.
• Statistical analysis was performed to compare marker levels and correlations.
• PSA levels were also assessed in both groups.

Main Results:

• BPH patients exhibited significantly higher plasma MDA levels (4.81±1.87 nmol/ml) compared to controls (3.69±1.56 nmol/ml, p<0.001).
• Plasma alpha-Tocopherol (0.85±0.12 mg/dl vs 1.37±0.31 mg/dl) and Ascorbate (0.93±0.13 mg/dl vs 1.44±0.38 mg/dl) levels were significantly lower in BPH patients.
• An inverse correlation was observed between MDA and Ascorbate (r=-0.51, p=0.008) in BPH patients.

Conclusions:

• The study provides evidence for the association of oxidative stress with Benign Prostate Hyperplasia.
• Elevated lipid peroxidation and reduced antioxidant capacity are implicated in BPH pathogenesis.
• Further research is warranted to explore therapeutic strategies targeting oxidative stress in BPH.
