Objectives: To determine the effectiveness of alfuzosin on symptom reduction, patients' perceived health-related quality of life (HRQL) improvement, adverse outcomes, treatment failure, and progression to acute urinary retention and prostate surgery in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH) in a 1-year prospective, open-labeled study.
Methods: A total of 2829 patients (mean age 65.9 years) were included in the study and received either alfuzosin 2.5 mg three times daily or alfuzosin slow release 5 mg twice daily. The evaluation was based on the International Prostate Symptom Score (IPSS), the eighth IPSS question, and a nine-item BPH HRQL questionnaire (BPHQL9) exploring well-being, the patient's perceived sexual life, and BPH-specific interferences with activities.
Results: A total of 2442 patients (86. 3%) completed the study; the main reasons for noncompletion were adverse events (n = 141, 5.0%), lack of efficacy (n = 136, 4.8%), and death (n = 48, 1.7%); 121 patients (4.3%) underwent prostate surgery, and 33 patients (1.2%) experienced acute urinary retention. No correlation was found between noncompletion and prostate volume or baseline severity. The distribution of patients (in percentages) according to the IPSS, IPSS question 8, and BPHQL9 classes of severity (mild/moderate/severe) at baseline was 1.9/49.0/49.1, 0. 7/65.5/33.8, and 7.7/50.4/41.9, respectively, and at 1 year was 47. 4/50.3/2.4, 34.1/64.9/1.0, and 39.0/50.9/10.1, respectively. The IPSS (19.5 +/- 0.1) was reduced by 49.6% (9.9 +/- 0.1) at 6 months and by 53.8% (11.1 +/- 0.1) at 12 months. Symptom reduction strongly correlated with the initial symptom severity (P <0.0001). The BPHQL9 score (34.6 +/- 0.3) gradually improved up to 12 months (52 +/- 0.4; +93.3%), and this improvement involved all three dimensions. Vertigo (n = 53, 1.9%), hypotension (n = 47, 1.6%), and dizziness (n = 16, 0. 6%) were the most frequent adverse events.
Conclusions: This study confirms the effectiveness of alfuzosin and the need to include HRQL measurement in the decision-making process when assessing patients with lower urinary tract symptoms.
