Background. Benign prostatic hyperplasia (BPH), which is mostly prevalent in older men, is associated with compression of the prostatic urethra and manifests as lower urinary tract symptoms. Its pathological characteristics include abnormal proliferation of stromal and glandular epithelial cells, leading to prostate enlargement. Current data highlight additional factors in the pathogenesis of this disease, notably oxidative stress and chronic inflammation.
Materials and Methods. Prostate tissue was obtained from 35 patients aged 58–72 years via transurethral resection. Prostate tissue from three patient groups was utilized. Group 1 consisted of patients with BPH (n = 7) weighing up to 40 grams (control group); Group 2 included patients with BPH (n = 14) weighing 45–98 grams; Group 3 comprised patients with benign prostatic hyperplasia and chronic inflammation (adenoprostatitis) weighing 45–98 grams (n = 14). The levels of malondialdehyde and reduced glutathione, as well as the activities of glutathione peroxidase and glutathione reductase, were determined in the tissues.
Results. In large-scale prostate hyperplasia and prostate hyperplasia associated with prostatitis, lipid peroxidation processes escalate in prostate cells, as indicated by an increase in malondialdehyde concentration. The elevation in lipid peroxidation levels is accompanied by a decrease in the activity of antioxidant defense enzymes glutathione peroxidase and glutathione reductase, alongside a reduction in the concentration of reduced glutathione. The balance within the pro-/antioxidant system is more significantly disrupted in cases of prostate hyperplasia associated with prostatitis.
Conclusion. In large-scale prostate hyperplasia and hyperplasia associated with histologically confirmed prostatitis, lipid peroxidation processes intensify within the cells, which is confirmed by rising levels of malondialdehyde. The increase in lipid peroxidation is accompanied by a decline in glutathione peroxidase and glutathione reductase activities, as well as a decrease in the concentration of reduced glutathione. In prostate hyperplasia accompanied by adenoprostatitis, the balance in the pro-/antioxidant system is disrupted to a greater extent.
