Evaluation of a 3-item screening tool to identify men with benign prostatic enlargement/obstruction in a primary care cohort.

BACKGROUND: Benign prostatic hyperplasia (BPH), a progressive condition and common cause of lower urinary tract symptoms (LUTS), is underdiagnosed in primary care, impacting patient outcomes. Here, we evaluate the utility of a BPH screening tool in general practice, to identify men confirmed to have BPH after urologist assessment of diagnostic test results. METHODS: A 3-item questionnaire was developed to discriminate between LUTS due to BPH versus other conditions and was translated and validated cross-culturally. Its utility was assessed in a cohort study (FDC116114/NCT02757963) conducted in 47 centers across France, Germany, Italy, Russia, and Spain. The study enrolled men ≥50 years of age presenting to general practice clinics with a score of ≥3 on the BPH screening tool or ≥8 on the International Prostate Symptom Score (IPSS). In total, 561 men completed the study. The primary endpoint was the proportion of patients with a urologist-confirmed BPH diagnosis among those with a positive result on the BPH screening tool (score ≥3) and serum prostate specific antigen (PSA) ≥2 ng/mL. RESULTS: The primary endpoint was fulfilled; 88.3% (95% CI: 84.9, 91.2) of patients had urologist-confirmed BPH diagnoses among those with positive results on the BPH screening tool and serum PSA≥2 ng/mL, similar to the proportion seen with IPSS≥8 and serum PSA≥2 ng/mL (87.7%; 95% CI: 84.6, 90.4). CONCLUSIONS: The BPH screening tool, in conjunction with serum PSA, demonstrated adequate predictive value by allowing general practitioners to quickly screen men presenting with different medical conditions but identified as having urological symptoms.

A prospective randomised placebo-controlled study of the impact of dutasteride/tamsulosin combination therapy on sexual function domains in sexually active men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).

OBJECTIVE: To prospectively assess the impact of the fixed-dose combination (FDC) of the 5α-reductase inhibitor (5ARI), dutasteride 0.5 mg and the α1 -adrenoceptor antagonist, tamsulosin 0.4 mg (DUT-TAM FDC) therapy on sexual function domain scores in sexually active men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH), using the Men's Sexual Health Questionnaire (MSHQ). PATIENTS AND METHODS: This European and Australian double-blind, placebo-controlled, parallel-group study was conducted at 51 centres. INCLUSION CRITERIA: age ≥50 years, International Prostate Symptom Score ≥12, prostate volume ≥30 cc, prostate-specific antigen 1.5-10 ng/mL. Patients were randomised 1:1 to DUT-TAM FDC therapy or placebo for 12 months. The change from baseline to Month 12 on the total MSHQ (primary endpoint) and MSHQ erection, ejaculation and satisfaction domains (secondary outcome) was assessed, using a mixed model repeated measures analysis. Safety was evaluated. RESULTS: The intention-to-treat population included 489 patients (243 DUT-TAM FDC therapy; 246 placebo). A significant decrease (worsening) was observed with DUT-TAM FDC therapy versus placebo on the total MSHQ score (-8.7 vs -0.7; standard error [se]: 0.81, 0.78; P < 0.001), and the ejaculation (-7.5 vs -0.6; se: 0.56, 0.55; P < 0.001) and satisfaction (-0.6 vs +0.3; se: 0.3, 0.29, P = 0.047) domains, but not the erection domain (-1.0 vs -0.5; se: 0.19, 0.19, P = 0.091). CONCLUSION: This is the first domain-specific quantitative evaluation of DUT-TAM FDC therapy on sexual function in men with LUTS secondary to BPH. The observed changes in the MSHQ with DUT-TAM FDC therapy were mainly driven by changes in the ejaculation domain. These findings will help give context to erectile and ejaculatory dysfunction AEs reported spontaneously in earlier 5ARI studies.
