[Morphological changes in prostatic tissue of patients with benign prostatic hyperplasia treated with permixon]

A pilot trial has been performed to assess effects of permixon on prostatic tissue in patients with benign prostatic hyperplasia (BPH). A total of 49 BPH and control patients entered the trial. 36 patients of the study group were randomized into 3 subgroups of 12 patients each. Permixon was taken in a standard dose of 320 mg/day for 3, 6 and 12 months, respectively. Mean duration of BPH was 3.7 years (0-8 years). Mean value of PCA was 6.0 ng/ml. The control group of 13 patients were not given permixon. Multifocal prostatic biopsy was performed in all the patients before and after the treatment or follow-up. Stromal-parenchymatous correlation in the study group significantly increased (by 59%)--from 3.28 (0.25-9.61) to 5.22 (1.20-10.67) (p = 0.0002). For the control group this correlation was insignificant. Permixon-treated patients demonstrated inhibition of prostatic epithelium proliferative activity by 32% (p = 0.0001) and a rise in the stage of proliferative centers development from stage II-III to IV-V. Intensity of inflammation in prostatic tissue decreased by 53% in the study group and insignificantly in the control group. Thus, permixon treatment of BPH leads to a significant rise in stromal-parenchymatous correlation due to inhibition of proliferative activity of prostatic epithelium and attenuation of inflammation.
