Visceral obesity and Inflammation Markers in Relation to Serum Prostate Volume Markers among Apparently Healthy Men

A., Alokail MS, Al-Daghri NM, Al-Attas OS, Alkharfy KM, Sabico S, Ullrich . 2011

BACKGROUND:

Prostate disease incidence is expected to rise among developing nations secondary to increased prevalence of obesity and the elderly. Although many case-control studies have associated obesity to prostate cancer aggressiveness, few have correlated markers of prostate pathology to biomarkers of visceral obesity and insulin resistance, using an apparently healthy cohort. This study aims to fill this gap.

MATERIALS AND METHODS:

The 219 consenting adult Arab men, aged 30-70 years, were included in this cross-sectional study. Demographics were noted and anthropometrics measured. Fasting blood samples were extracted, and glycaemic and lipid profile were determined using routine laboratory methods. Serum adipocytokines and inflammatory markers were measured using multiplex assays. Total prostate-specific antigen (tPSA), free PSA (fPSA), parathyroid-related protein (PTHrP) and endoglin were measured using enzyme-linked immunosorbent assays.

RESULTS:

Serum triglycerides and waist-hip ratio (WHR) were significantly and positively associated with circulating (tPSA) levels in all subjects (P < 0·01). Systolic blood pressure (SBP), adiponectin, active plasminogen activator inhibitor-1 (aPAI-1) and insulin-like growth factor-1 (IGF-1) had significant inverse associations to tPSA. Stepwise linear regression revealed that adiponectin, IGF-1, WHR and PTHrP explained 30% of variance in tPSA levels (P < 0·0001), while SBP, resistin and BMI explained 18·7% of variance in endoglin (P = 0·001).

CONCLUSIONS:

The associations of adiponectin and WHR strengthen the link between insulin resistance and visceral adiposity to prostate volume markers among apparently healthy Arab men. Follow-up studies are needed to extend these preliminary findings so that early interventions can be provided to those at increased risk.
