Relation between histological prostatitis and lower urinary tract symptoms and erectile function.

ABSTRACT: Chronic prostatitis (CP) significantly worsens a patient's quality of life (QOL), but its etiology is heterogeneous. Although the inflammatory process must be associated with CP symptoms, not all patients with benign prostatic hyperplasia and histological prostatitis complain of CP symptoms. The relation between the severity of histological inflammation and lower urinary tract symptoms (LUTS) and erectile function is not fully understood.This study comprised 26 men with suspected prostate cancer but with no malignant lesion by pathological examination of prostate biopsy specimens. LUTS were assessed by several questionnaires including the International Prostate Symptom Score (IPSS), QOL index, Overactive Bladder Symptom Score (OABSS), and the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and erectile function was assessed by the Sexual Health Inventory for Men. Prostate volume (PV) measured by transabdominal ultrasound, maximum flow rate by uroflowmetry, and serum concentration of prostate-specific antigen were also evaluated. All data collections were performed before prostate biopsy. Histological prostatitis was assessed by immunohistochemical staining with anti-CD45 antibody as the Quick score. The relation between the Quick score and several factors was assessed by Pearson correlation coefficient and a multivariate linear regression model after adjustment for PV.The Pearson correlation coefficient showed a correlation between the Quick score and several factors including PV, IPSS, QOL index, OABSS, and NIH-CPSI. A multivariate linear regression model after adjustment for PV showed only the NIH-CPSI to be associated with the Quick score. The relation between the Quick score and each domain score of the NIH-CPSI showed only the subscore of urinary symptoms to be an associated factor.We found a correlation only between histological prostatitis and LUTS, but not erectile dysfunction. Especially, the subscore of urinary symptoms (residual feeling and urinary frequency) was associated with histological prostatitis.

Project description:INTRODUCTION:Lower urinary tract symptoms (LUTS) affect ?60% of adult men and are associated with erectile dysfunction (ED) and sexual dissatisfaction. AIM:The aim of this study was to evaluate the relationship among male LUTS, ED, and sexual satisfaction. METHODS:This was a secondary analysis of the Brazil LUTS study, a cross-sectional, epidemiological survey conducted by telephone interview in 5 cities in Brazil. This analysis included men aged ?40 years. MAIN OUTCOME MEASURE:LUTS were identified using International Continence Society definitions. LUTS severity was assessed using the International Prostate Symptom Score questionnaire. Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5) questionnaire and sexual satisfaction was rated on a 5-point scale. RESULTS:2,433 men participated in the study. Of 2,183 men reporting data on LUTS, 873 (40%) had LUTS "about half the time" or more. The prevalence of ED and sexual dissatisfaction was 14.4% and 7.8%, respectively. The proportion of men reporting ED and sexual dissatisfaction was higher among men with LUTS (24.6% and 13.8%, respectively) than men without LUTS (8.7% and 4.5%, respectively; P < .001). LUTS severity was negatively correlated with IIEF-5 scores (r = -0.199; P < .001); we estimated a 0.431-point decrease in IIEF-5 score per 3-point increase in International Prostate Symptom Score. Increased age and the presence of LUTS were associated with a greater chance of ED and sexual dissatisfaction; depression/anxiety and diabetes were associated with a greater chance of sexual dissatisfaction only. Among men with LUTS, urgency with fear of leaking, urgency urinary incontinence, and nocturnal enuresis were associated with a greater chance of ED, whereas slow stream and urgency urinary incontinence were associated with a greater chance of sexual dissatisfaction. CONCLUSION:These results demonstrate that the presence of LUTS is associated with an increased chance of ED and sexual dissatisfaction in Brazilian men and reinforce the importance of a comprehensive assessment of these conditions.

Project description:The role of fruit and vegetable (FV) intake in relation to prostate health remains inconclusive. This 4-year longitudinal study aims to explore the association of FV intake and the development of lower urinary tract symptoms (LUTS, a cluster of chronic urinary symptoms occurring in bladder, prostate and urethra), incidence of symptomatic benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) in Chinese elderly men. Data were obtained from a 4 years longitudinal study (Mr OS Hong Kong, the largest prospective study on bone health in Chinese elderly). Two thousand Chinese men aged 65 years and older were recruited from the local community, of whom 1998 (99.9%) at baseline and 1564 (78.2%) at 4-year follow-up reported data on LUTS, which were evaluated by a validated International Prostate Symptoms Scale (IPSS). Erectile function was evaluated by the International Index of Erectile Dysfunction-5 (IIEF-5) questionnaires at 2- (n = 386) and 4-year (n = 475) follow-ups. Dietary intake was assessed using a validated food frequency questionnaire at baseline. Analysis was conducted using multivariate linear and logistic regression. For total FV and most of their subclasses, moderate consumption had the lowest mean changes of LUTS; we thus applied the moderate levels as the reference in the regression models. The high levels of total FV intake (>350 g/1000 kcal/day) were significantly associated with reduced IPSS by scores of -1.174 ± 0.459 (or -17.3% of basal IPSS, P = 0.011) relative to the moderate groups (250-350 g/1000 kcal/day). FV consumption had no significant association with the score change of ED or the odds of sexual activities at 4-year (all P > 0.05). High intake of dark and leafy vegetables (>50 g/1000 kcal/day) significantly reduced the risk of LUTS progression by 37.2% [odds ratio (OR) (95% confidence interval, 95% CI): 0.628 (0.466∼0.848), P = 0.002] or risk of symptomatic BPH by 34.3% [OR (95% CI): 0.657 (0.442-0.976), P = 0.038] after 4 years compared with the moderate group (25-50 g/1000 kcal/day). Adequate FV intakes, especially dark and leafy vegetables, were associated with improved LUTS among Chinese elderly men, but lack an association with ED and sexuality.
