Abstract

Purpose:In men, complaints of nocturia causing poor sleep are often attributed to benign prostatic hyperplasia and treated with benign prostatic hyperplasia medications. We assessed whether treating lower urinary tract symptoms with dutasteride altered either nocturia or sleep quality using data from REDUCE.Materials and Methods:REDUCE was a 4-year randomized, multicenter trial comparing dutasteride 0.5 mg/day vs placebo for prostate cancer chemoprevention. Study participants were men considered at increased risk for prostate cancer. Eligibility included age 50-75 years, prostate specific antigen 2.5-10 ng/ml, and 1 negative prostate biopsy. At baseline, 2 years and 4 years, men completed the International Prostate Symptom Score and Medical Outcomes Study Sleep Scale, a 6-item scale assessing sleep. To test differences in nocturia and Medical Outcomes Study Sleep Scale over time, we used linear mixed models adjusted for baseline confounders. Subanalyses were conducted in men symptomatic from lower urinary tract symptoms, nocturia, poor sleep, or combinations thereof.Results:Of 6,914 men with complete baseline data, 80% and 59% were assessed at 2 and 4-year followup, respectively. Baseline characteristics were balanced between treatment arms. Dutasteride improved nocturia at 2 (-0.15, 95% CI -0.21, -0.09) and 4 years (-0.24, 95% CI -0.31, -0.18) but did not improve sleep. When limited to men symptomatic from lower urinary tract symptoms, nocturia, poor sleep or combinations thereof, results mirrored findings from the full cohort.Conclusions:In men with poor sleep who complain of nocturia, treatment of lower urinary tract symptoms with dutasteride modestly improves nocturia but has no effect on sleep. These results suggest men with poor sleep who complain of nocturia may not benefit from oral benign prostatic hyperplasia treatment.
