Efficacy of Fesoterodine on Nocturia and Quality of Sleep in Asian Patients With Overactive Bladder

Electroacupuncture for lower urinary tract symptoms in men with benign prostatic hyperplasia: study protocol for a randomised controlled trial

INTRODUCTION

Benign prostatic hyperplasia (BPH) is a condition commonly seen among men aged over 40, significantly affecting their quality of life and typically accompanied by lower urinary tract symptoms (LUTS). Acupuncture presents a potentially effective treatment option; however, the exact effects remain uncertain. Therefore, we design this multicentre randomised trial to evaluate the efficacy and safety of electroacupuncture (EA) for relieving LUTS in men with BPH.

METHODS AND ANALYSIS

A two-arm, sham-controlled, subject-blinded and assessor-blinded trial will be conducted in 11 hospitals in China to compare EA with sham electroacupuncture (SA) in treating moderate to severe LUTS of BPH among men aged 40-80. A total of 306 eligible male patients will be recruited and assigned at a 1:1 ratio to receive either EA or SA for 24 sessions over a succession of 8 weeks, with 24 weeks of follow-up. The primary outcome will be the proportions of participants with at least 30% reduction in the International Prostate Symptom Score total score from baseline at weeks 8 and 20. All statistical analyses will be conducted in accordance with the intention-to-treat principle, and a two-tailed p value less than 0.05 will be considered statistically significant.

ETHICS AND DISSEMINATION

The trial has been approved by the institutional review board of Guang'anmen Hospital (2022-203-KY), as well as other recruitment centres. Each participant will receive the detailed information of the trial, and sign the written informed consent. The results of the trial are expected to be published in a peer-reviewed journal.

Efficacy and Safety of Combination Therapy With Vaginal and Urethral Erbium-Doped Yttrium-Aluminum-Garnet (Er:YAG) Laser for Overactive Bladder With Urinary Incontinence

OBJECTIVE

This retrospective cohort study with propensity score (PS) matching aimed to evaluate the efficacy and safety of a combination therapy with vaginal and urethral erbium:yttrium aluminum garnet laser (VEL+UEL) (SP Dynamis; Fotona d.o.o., Ljubljana, Slovenia) in the treatment of overactive bladder with urinary incontinence (OAB-wet).

METHODS

The study included female OAB-wet patients aged 65 and above who were already taking OAB medication. Data obtained from electronic medical records were subjected to propensity score matching. All patients received instructions on pelvic floor exercises and were prescribed an appropriate dose of OAB medication. The VEL+UEL group (n=30) underwent three monthly laser sessions, while the control group (n=30) did not receive the treatment. Clinical outcomes were evaluated using the Overactive Bladder Symptom Score (OABSS), International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), three-day urination diary, and Vaginal Health Index Score (VHIS). Medication usage and adverse events were also assessed. Statistical analysis and R code were performed using the AI chatbot GPT-4.0.

RESULTS

The VEL+UEL group showed significant improvements in OABSS score, ICIQ-SF score, voided volume, daytime frequency, nocturia, and VHIS after 12 months of treatment (p<0.001). Notably, 13.3% of patients transitioned from OAB-wet to OAB-dry. In contrast, the control group did not exhibit significant changes. Medication use was significantly reduced in the VEL+UEL group compared to the control group (p<0.001). No long-term side effects were reported.

CONCLUSION

Combination therapy with VEL+UEL demonstrated efficacy and safety in the treatment of OAB-wet. Improvements in OAB symptoms, voided volume, frequency, nocturia, and vaginal health were observed, with a subset of patients transitioning to OAB-dry. VEL+UEL therapy offers a potential treatment option for OAB-wet, reducing medication use and improving patient outcomes. Further research is warranted to investigate the mechanism, long-term effects, safety, and cost-effectiveness of VEL+UEL therapy.

A meta-analysis on the characteristics of placebo effects on urinary function in placebo-controlled clinical trials among Japanese patients

OBJECTIVES

This study aimed to assess the effect sizes, changes over time, and ethnic differences in placebo effects on urinary function among Japanese patients participating in clinical trials.

METHODS

A meta-analysis of 30 Japanese placebo-controlled clinical trials was conducted to determine the placebo effects on three functions: daily urinary frequency, nocturnal urinary frequency, and average urine volume per void.

RESULTS

The I-square heterogeneity values for the basic values of the three functions ranged from 84.5% to 97.9%, with differences among trials. Longitudinal analysis (1 to 12 weeks) indicated an enhanced placebo effect for up to 8 weeks and no consistency among trials on nocturnal urinary frequency (p < 0.01), unlike those on daily urinary frequency and average urine volume per void (p = 1.0). Based on the random-effects model, the mean differences in urinary frequency at 4, 8, and 12 weeks were -0.70 (-0.80; -0.60), -1.06 (-1.16; -0.96), and -1.18 (-1.34; -1.01), respectively. Furthermore, the mean difference (95% confidence interval) in nocturnal urinary frequency and volume of urination per void at 12 weeks was -0.63 (-0.94; -0.31) and 9.67 (7.25; 12.1), respectively.

CONCLUSIONS

My findings suggest an increase in the strength of placebo effects over time (up to 8 weeks). A comparison of my results to those published in previous global reports showed no meaningful differences in placebo effects among ethnic groups. The consistent placebo effect size on urinary function could be an external indicator in clinical trials.

Obesity and Voiding Parameters in a Community-Based Population of Okinawa, Japan: Kumejima Digital Health Project (KDHP)

(1) Background: Evidence has accumulated regarding the etiology of lower urinary tract symptoms associated with obesity and metabolic syndrome. Therefore, the present study aimed to identify which subjectively and objectively measured voiding parameters were associated with obesity in a community-based population. (2) Methods: Voiding parameters on a self-administered questionnaire and a digital self-health monitoring system for urine excretion (s-HMSU) were compared between participants with and without obesity, defined as a body mass index ≥ 25 kg/m2 (n = 30 and 29, respectively), from a community in Okinawa, Japan. Logistic regression analysis was employed to calculate the odds ratios of abnormalities in voiding parameters for the obese group, with the non-obese group serving as a reference. (3) Results: The obese group had odds ratios of 5.17 (95% confidence interval: 1.33−20.0) for shortened hours of undisturbed sleep (<302 min) by s-HMSU and 7.65 (1.88−31.1) for nighttime urinary frequency by a questionnaire after adjusting for age and sex. In addition, the obese group had an adjusted odds ratio of 2.27 (0.76−6.78) for decreased maximum bladder capacity (<212 mL) by s-HMSU. (4) Conclusion: the results of the present study suggest that nocturia and shortened hours of undisturbed sleep are signs of obesity.

Development of the Nocturia Sleep Quality Scale: a patient-reported outcome measure of sleep impact related to nocturia

BACKGROUND/OBJECTIVE

Nocturia's impact on sleep causes significant burden for patients. This study aimed to develop a novel patient-reported outcome (PRO) measure, the Nocturia Sleep Quality Scale (NSQS), for the assessment of the impact of nocturia (defined as ≥2 nocturnal voids/night) on sleep.

METHODS

Sleep-related concepts were identified through a targeted literature review, after which in-depth concept elicitation interviews with patients with a clinical diagnosis of nocturia were conducted. Draft items were generated to address concepts identified as important, meaningful, and relevant. Items were further refined through three iterative sets of cognitive debriefing interviews to optimize instructions, question wording, and response options. Two sleep research experts also provided input.

RESULTS

The literature review and data from 18 concept elicitation interviews provided the basis for a comprehensive set of concepts. Constant comparative analysis was used to identify themes and support item development. The draft questionnaire consisted of 14 items with item-specific response scales. Wording and scaling of the items was optimized based on feedback from the 22 cognitive debriefing interviews and expert input. The results confirmed the completeness and relevance of the NSQS, providing support for the content validity and ability of items to reflect patient perception of nocturia-related sleep impacts.

CONCLUSIONS

The 6-item NSQS assesses the impact of nocturia on sleep by evaluating nighttime awakenings, sleep quantity, and sleep quality. The NSQS is self-administered and is intended to assess change in nocturia's impact on sleep after treatment in a standardized manner. Psychometric evaluation is under way to describe key measurement properties.

The discrepancy between European Association of Urology (EAU) guidelines and daily practice in the evaluation and management of nocturia: results of a Dutch survey

BACKGROUND AND OBJECTIVE

In addition to the evaluation of voiding symptoms, in the evaluation of patients with nocturia, one should also consider other related causes such as sleep disorders, obstructive sleep apnoea (OSAS), diabetes and heart failure. In this study, we have aimed to assess the current knowledge and implementation of the EAU guidelines regarding nocturia in common urological practice in the Netherlands.

SETTING AND PARTICIPANTS

In a national cross-sectional survey distributed among 450 urologists and urology residents in the Netherlands, the implementation of the recommendations of the European Association of Urology (EAU) guidelines on nocturia evaluation and management was studied.

RESULTS AND LIMITATIONS

This survey revealed that only some aspects of the EAU guidelines are applied in the daily clinical practice and that some important parts are not. For example, only a minority asks about alcohol consumption and symptoms suggestive for diabetes or OSAS. In addition, a majority reported to use a bladder diary for 1-3 days instead of for a minimum of 3 days as recommended by the EAU guidelines. In the management of nocturia, a trial of timed diuretic therapy is only reported by a minority, whereas the use of beta-3 antagonists, which is not mentioned in the guidelines, is applied by a large majority. Desmopressin recommended for nocturnal polyuria is prescribed by two-third of Dutch urologists.

CONCLUSIONS

These observations mandate better education and campaigns to raise the awareness on the EAU-guideline recommendations for nocturia.

[Impact of medical and surgical treatments of LUTS on nocturia]

INTRODUCTION

Nocturia is the most frequently reported lower urinary tract symptom, but the impact of medical and surgical treatments on this symptom remains poorly evaluated. The objective of this work was to carry out a systematic review of the literature on the medical and surgical management of nocturia in men with bladder outlet obstruction due to benign prostatic hyperplasia.

MATERIAL AND METHOD

A systematic review of the literature was conducted including the effects of medical and surgical treatments on nocturia. Articles were selected by 3 independent reviewers before being analyzed and synthesized.

RESULTS

Among medical treatments, the most effective on nocturia seems to be desmopressin. Nevertheless, prescribing restrictions to men under 65 years of age hinder its use in routine practice. The effect of other medical treatments remains modest, although significant compared to placebo groups. The decrease in the number of nocturia would decrease from 0.25 to 0.7 in placebo group and from 0.29 to 1.1 in active treatment groups (alpha blocker, diuretic, anti-inflammatory, IPDE-5, 5 alpha reductase inhibitor). Surgical treatments seem to be more effective on nocturia. Although persistent in half of the patients undergoing surgery, the number of nocturia episodes decreased in 70% of them.

CONCLUSION

Nocturia is one of the most common urinary symptoms and the one that responds the least to the proposed medical and surgical treatments. The information given to patients by urologists must emphasize the modest effects to be expected in this area.

Association of Pharmacologic Treatment of Urgency Urinary Incontinence With Sleep Quality and Daytime Sleepiness

OBJECTIVE

To evaluate the association between pharmacologic therapy for urgency urinary incontinence (UUI) and sleep quality.

METHODS

We conducted a planned secondary data analysis of sleep outcomes in a previously conducted multicenter, double-blind, 12-week randomized trial of pharmacologic therapy for urgency-predominant incontinence among community-dwelling women self-diagnosed using the 3-Incontinence Questions questionnaire. Participants (N=645) were assigned randomly to 4-8 mg antimuscarinic therapy daily or placebo. At baseline and 12 weeks, participants completed a validated voiding diary to evaluate incontinence and voiding symptoms, the Pittsburgh Sleep Quality Index to evaluate sleep quality, and the Epworth Sleepiness Scale to evaluate daytime sleepiness.

RESULTS

Mean (SD) age was 56 (±14) years, 68% were white, and 57% had poor sleep quality (Pittsburgh Sleep Quality Index score greater than 5). Mean frequency of any urinary incontinence and UUI was 4.6 and 3.9 episodes/d, respectively. After 12 weeks, women randomized to the antimuscarinic group reported greater decrease compared with the placebo group in UUI frequency (0.9 episodes/d; P<.001) and diurnal and nocturnal voiding frequency (P<.05). As compared with the placebo group, women in the antimuscarinic group also reported greater improvement in sleep quality (total Pittsburgh Sleep Quality Index score 0.48; P=.02) with greater improvement in sleep duration and sleep efficiency subscales (P<.05). The intervention did not affect daytime sleepiness.

CONCLUSION

Pharmacologic treatment of UUI is associated with decreased incontinence frequency and nocturia and improvement in overall sleep quality, sleep duration, and sleep efficiency.

Efficacy and safety of fesoterodine treatment for overactive bladder symptoms in elderly women with and without hypertension

OBJECTIVE

To assess fesoterodine treatment in elderly women with overactive bladder with and without hypertension.

METHODS

Data for 2527 elderly women with overactive bladder symptoms, including urgency urinary incontinence, were pooled from 10 double-blind, placebo-controlled fesoterodine studies.

RESULTS

A total of 1523 elderly women (60.3%) had a history of hypertension, and 1004 women (39.7%) had no hypertension history. Overactive bladder symptoms, mean bodyweight and mean body mass index at baseline were significantly higher in women with overactive bladder and hypertension versus those without hypertension (P < 0.05). Statistically significant improvements in overactive bladder symptoms at week 12 were observed for fesoterodine treatment versus placebo in women with hypertension and those without (P < 0.05). The diary-dry rate (no urgency urinary incontinence episodes), the proportion with less than eight micturitions/24 h, overactive bladder symptom bother and health-related quality of life were also statistically significantly improved by fesoterodine treatment in both populations. Incidence of treatment-related adverse events with fesoterodine was similar in women with hypertension (39.3%) and without hypertension (44.6%). Dry mouth and constipation were the most common treatment-related adverse events with fesoterodine in women with hypertension (26.2% and 5.2%, respectively) and without hypertension (30.5% and 8.0%).

CONCLUSIONS

A relationship among the severity of overactive bladder symptoms, hypertension and obesity in elderly women is suggested. Fesoterodine provides significantly greater improvements in overactive bladder symptoms and health-related quality of life versus placebo in women with or without hypertension. Hypertension does not appear to affect the efficacy and safety of fesoterodine in elderly women with overactive bladder symptoms, including urgency urinary incontinence.

Influence of Daytime or Nighttime Dosing with Solifenacin for Overactive Bladder with Nocturia: Impact on Nocturia and Sleep Quality

We compared changes in nocturia and sleep-related parameters between daytime and nighttime solifenacin dosing in patents with overactive bladder (OAB) and nocturia. We comparatively analyzed the data of a 12-week prospective, open-label, multicenter, randomized study. All 127 patients who presented to 5 centers in Korea for the treatment of OAB with nocturia between January 2011 and December 2013 were enrolled in this study. The patients were divided into 2 groups by medication timing: group 1, daytime (n = 62); and group 2, nighttime (n = 65). The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and Athens Insomnia Scale (AIS) were used to assess OAB symptoms and sleep quality. We evaluated the parameter changes before and 12 weeks after daytime or nighttime solifenacin administration. Baseline data, which included sex, age, body mass index (BMI), total AIS, IPSS, and OABSS, did not differ between the 2 groups. Total IPSS, OABSS, and total AIS significantly improved after solifenacin administration regardless of timing (P < 0.001). After solifenacin administration, the number of nocturia episodes decreased in the group 1 and 2 (P < 0.001). There were no significant intergroup differences in changes in AIS, IPSS, OABSS, and number of nocturia episodes 12 weeks after solifenacin administration. Treating OAB with solifenacin may improve nocturia and sleep quality, but advantages did not differ significantly by medication timing.

Nocturia: aetiology and treatment in adults

Nocturia is an extremely common condition that has major sequelae for affected patients. Through disruption of sleep, nocturia impairs quality of life and worsens health outcomes, and is associated with a variety of morbidities including diabetes, coronary artery disease, obstructive sleep apnoea, obesity, metabolic syndrome, and depression. Unsurprisingly, several studies have also linked nocturia with reduced survival. Nocturia is not simply a consequence of lower urinary tract disease; rather, it is a multifactorial disorder that is often a manifestation of an underlying renal or systemic disease. Through the use of the frequency volume chart, clinicians can accurately quantify nocturia and determine its aetiology. Evaluation of quality of life and sleep using simple measures is essential in order to assess the impact of nocturia on a patient. Numerous treatment options for nocturia exist, but most are associated with minor benefit or lack sufficient evidence supporting their use. By systematically analysing an individual's causes of nocturia, clinicians can design appropriate treatment strategies to most effectively treat this condition.

Fesoterodine clinical efficacy and safety for the treatment of overactive bladder in relation to patient profiles: a systematic review

OBJECTIVE

To summarize published evidence on the pharmacology, efficacy, and safety of fesoterodine for the treatment of overactive bladder (OAB) symptoms in relation to patient clinical and demographic profiles.

METHODS

A systematic review of published articles on fesoterodine was conducted via a PubMed search. Articles were identified using the search term fesoterodine, with limits of human species and abstract available. Review and meta-analysis articles, validation studies, articles focused on treatment compliance/adherence, meeting abstracts, and articles not focused on oral fesoterodine administration in human subjects were excluded. Data from retained articles were summarized descriptively.

RESULTS

Of 137 articles identified, 61 (15 articles on the pharmacology and 46 articles on the efficacy and/or safety of fesoterodine) met inclusion criteria. Superiority trials demonstrated the additional efficacy of fesoterodine 8 mg versus fesoterodine 4 mg and tolterodine extended release 4 mg in treating OAB. Prospective trials in specific patient populations indicated beneficial effects of fesoterodine in elderly patients, vulnerable elderly patients, patients dissatisfied with or with a suboptimal response to previous antimuscarinic therapy, patients with urge urinary incontinence (UUI) or nocturnal urgency, and men with persistent LUTS during alpha-blocker treatment. With two effective doses, the fesoterodine dose can be adjusted to achieve optimal efficacy and tolerability in individual patients. The most common adverse events during fesoterodine treatment are dry mouth and constipation.

CONCLUSIONS

Extensive evidence demonstrates the efficacy and safety of fesoterodine in relieving OAB symptoms, including urgency, urinary frequency, UUI, and nocturnal urgency, in patients with various clinical and demographic profiles. Trial results provide valuable information on fesoterodine treatment in specific patient populations, including both elderly and vulnerable elderly patients. Potential limitations of this review are that only English language articles in PubMed were searched and included.

Once-daily oxybutynin patch improves nocturia and sleep quality in Japanese patients with overactive bladder: Post-hoc analysis of a phase III randomized clinical trial

OBJECTIVES

To investigate the efficacy of a once-daily oxybutynin patch for nocturia, and its influence on sleep quality in patients with overactive bladder.

METHODS

We carried out post-hoc analysis of a phase III, randomized, double-blind, comparative study in which an oxybutynin patch was administered once daily for 12 weeks to Japanese patients with overactive bladder. Patients with a baseline mean of one or more episodes of nocturia per night (data from voiding diaries) were analyzed. The mean number of micturitions, mean voided volume per micturition, mean first voided volume at night, mean sleep duration, and hours of undisturbed sleep were compared between the once-daily oxybutynin patch group and the placebo group. All parameters were expressed as the least squares mean values.

RESULTS

The analysis included 576 patients. The number of nocturia episodes decreased by 0.66 in the oxybutynin patch group versus 0.51 in the placebo group (P = 0.0249). Also, the voided volume per nocturnal micturition and the first voided volume at night showed a significant increase in the oxybutynin patch group compared with the placebo group (P = 0.0073 and P = 0.0005, respectively). The hours of undisturbed sleep showed significant prolongation by 76.14 min in the oxybutynin patch group versus 56.07 min in the placebo group (P = 0.0257).

CONCLUSIONS

Oxybutynin patch treatment reduces the number of nocturia episodes and prolongs the hours of undisturbed sleep, thus improving sleep quality and sleep-related quality of life in patients with overactive bladder.

Medication adherence in the management of nocturia: challenges and solutions

OBJECTIVE

Nocturia affects millions of men and women. No prior reviews or meta-analyses have explored the issue of adherence in nocturia patients. The objective of our study was to examine the attributes and their interaction that might impact pharmacological adherence in nocturia care using a conceptual model of adherence.

MATERIALS AND METHODS

A literature search of the Medline, PubMed, Embase, PsycInfo, and CINAHL databases for studies published between January 1990 and June 2014 was conducted. We developed a conceptual model in order to facilitate our review.

RESULTS

Currently, multiple treatment options for nocturia exist, depending on the underlying cause. Adherence to nocturia treatment and outcomes are complex and intertwined, and nonadherence to nocturia treatment is common. In 15 studies meeting eligibility criteria, behavioral and pharmacologic interventions for nocturia were associated with reduced nocturia symptoms. Urinary symptoms that are associated with nocturia need individualized management depending on renal and hepatic function, medical comorbidities, and ongoing medication use in a patient. Another important factor related to adherence is the bother. Although nocturia is defined as nighttime-voiding frequency of one or more, not all persons may find this bothersome. The degree of bother is subjective, and may change from person to person. However, there is no information related to the association between bother and adherence to medication or behavioral treatments for nocturia. Medication dosing convenience, preference, and cost play important roles in adherence. We present a patient-centered conceptual model that brings together the various dimensions of medication adherence for nocturia.

CONCLUSION

Few studies have explored adherence to medication and related factors in the care of nocturia. Our conceptual model can aid development of interventions to improve adherence to nocturia medications.
