| Résumé : | Objectives: Oxidative stress is associated with the development of BPH and might be modulated by several factors. Myeloperoxidase (MPO) has recently been observed in prostate tissue. Our goal was to investigate the correlation between MPO and the prostate volume. Material and methods: Hundred and twenty-one patients (48–70 years) with a filled IPSS were prospectively included. Blood sampling (PSA, testosterone, Angiotensin II (AngII), MPO, Mox-LDL) and transrectal ultrasound of the prostate were performed with total volume (TV) and transitional zone volume (TZ) measurements. For correlation, univariate analyses were depicted by Pearson's coefficient. Multilinear regression analysis used a stepwise backward selection of the explicative variables. Results: In multivariate analysis, the TV was positively correlated to the combination of age and Ang II but negatively to MPO specific activity (Std Coef = −0.272, P = 0.004). Significant correlations were confirmed between TZ, age and MPO specific activity but not with Ang II. A negative correlation between TZ and MPO specific activity was also observed (Std Coef = −0.21, P = 0.016). No correlation was found with Mox-LDL. Conclusions: Negative correlation between MPO and prostate volume was observed but careful interpretations may be endorsed and longitudinal study is necessary. It seems relevant to focus on the potential contribution of MPO in the development of prostatic diseases as this enzyme can also promote DNA oxidation. Level of evidence: 4. |
