Eur J Obstet Gynecol Reprod Biol 2024; 295:59-64. [PMID: 38340591 DOI: 10.1016/j.ejogrb.2024.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 01/23/2024] [Accepted: 02/05/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVE To evaluate the effect of body mass index (BMI) on the prevalence of overactive bladder syndrome (OAB), severity of symptoms, and quality of life in affected patients. METHODS We conducted a prospective cross-sectional study of 1351 consecutive patients who were recruited between June 2021 and May 2022. Patients were divided according to BMI (normal: <25.0, overweight: 25-29.9, obese: ≥30) and menopausal status. The latter were divided according to the presence or absence of urinary incontinence in the normal, wet-OAB and dry-OAB groups. A validated questionnaire, the International Consultation on Incontinence Questionnaire in Overactive Bladder (ICIQ-OAB), in the English and Arabic languages was used. RESULTS A total of 1351 patients were included. For women who were overweight, there was a greater prevalence of dry-OAB (p = 0.02), However, the prevalence of both dry and wet-OAB were higher in obese women (p < 0.00001). Compared to women with a normal BMI, women who were overweight or obese had a greater likelihood of developing abnormal daytime urine frequency and nocturia, with p values ≤ 0.01. The ORs of overweight and obese women were 3.1 and 5.3, respectively, for experiencing wet OAB in comparison to women with a normal BMI. Additionally, the odds of developing severe OAB in overweight and obese women were 5.8 and 18.6, respectively, which negatively affects their quality of life (QoL). CONCLUSION The risk of developing OAB symptomatology is significantly greater in overweight and obese patients. As BMI increases, the symptomatology, perceived discomfort and QoL of patients with OAB worsen.

Park JS, Choi SB, Jang WS, Kim J, Ham WS. Risks of Dementia After Treatment with an Anticholinergic, Beta-3 Agonist, or Combination of Both for an Overactive Bladder: A Korean National Cohort Study. Eur Urol Focus 2024:S2405-4569(24)00019-1. [PMID: 38388215 DOI: 10.1016/j.euf.2024.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/15/2023] [Accepted: 02/11/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND AND OBJECTIVE An overactive bladder (OAB) is primarily managed with behavioural therapy and using anticholinergics and beta-3 agonists. Reports have shown that the use of anticholinergics by OAB patients was associated with an increased risk of new-onset dementia compared with those using beta-3 agonists. This study compares the risks of dementia among patients with an OAB starting on a beta-3 agonist alone, an anticholinergic alone, or a combination treatment. METHODS Using data from the Korean National Health Insurance Service database, we studied a nationwide population cohort comprising patients newly diagnosed with an OAB who initiated their OAB medications between 2015 and 2020. The treatment types were categorised as anticholinergics (oxybutynin, solifenacin, tolterodine, trospium, fesoterodine, flavoxate, and propiverine) alone, a beta-3 agonist (mirabegron) alone, and combination therapy (an anticholinergic plus the beta-3 agonist). To evaluate the impact of cumulative drug exposure, we quantified the cumulative exposure to solifenacin and mirabegron as cumulative defined daily doses (cDDDs) using proportional hazards regression analyses, adjusted for factors known to be associated with dementia. KEY FINDINGS AND LIMITATIONS Among the study's 3 452 705 patients, 671 974 were new users of a beta-3 agonist alone (19.5%), 1 943 414 new users of anticholinergics alone (56.3%), and 837 317 receiving combination therapy (24.3%). The most common anticholinergic used both alone and as part of a combination treatment was solifenacin (42.9% and 56.3%, respectively). There was an increased risk of dementia between the users of an anticholinergic alone (adjusted hazard ratio [aHR] = 1.213; 95% confidence interval [CI], 1.195-1.232) and those taking a combination treatment (aHR = 1.345; 95% CI, 1.323-1.366) compared with the users of beta-3 agonists alone after the adjustment of covariates. However, the incidence of dementia was also significantly higher, with an increase in the cumulative dose of mirabegron (aHR = 1.062 [1.021-1.106] for 28-120 cDDDs and aHR = 1.044 [1.004-1.084)] for patients who received >121 cDDDs compared with those who received <27 cDDDs). A marked increased risk of dementia was associated with the use of solifenacin, tolterodine, fesoterodine, and propiverine, both separately and in combination with mirabegron. CONCLUSIONS AND CLINICAL IMPLICATIONS In this large Korean cohort, the use of anticholinergics with or without a beta-3 agonist increased the risk of new-onset dementia compared with the use of a beta-3 agonist alone. Given that the risk of dementia was most significantly elevated with combination treatments, care should be taken when considering combination treatment for OAB patients with risk factors for dementia. Furthermore, there could be a possible association between beta-3 agonists and dementia, although future studies are needed. PATIENT SUMMARY This study investigated the risk of dementia induced by overactive bladder (OAB) treatment in a large Korean cohort. Two representative OAB treatment drugs, anticholinergics and beta-3 agonists, both increased the risk of new-onset dementia. Clinicians should be cautious in using OAB treatment drugs since no drugs could be concluded as safe.

Eur Geriatr Med 2023; 14:733-746. [PMID: 37245173 DOI: 10.1007/s41999-023-00798-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 05/10/2023] [Indexed: 05/29/2023]
Abstract
PURPOSE We aimed to outline the existing information and the underlying mechanisms of risk of falls associated with the use of urinary antimuscarinics for overactive bladder (OAB) or alpha-blockers for benign prostatic hyperplasia (BPH) in older adults. In addition, we aimed to provide assistance to clinicians in decision-making about (de-)prescribing these drugs in older adults. METHODOLOGY Based on a literature search in PubMed and Google Scholar, we reviewed the literature, and identified additional relevant articles from reference lists, with an emphasis on the most commonly prescribed drugs in OAB and BPH in older patients. We discussed the use of bladder antimuscarinics and alpha-blockers, their potential side effects related to falls, and the deprescribing of these drugs in older adults. RESULTS Urinary urgency or incontinence and lower urinary tract symptoms due to untreated OAB and BPH contribute to fall risk. On the other hand, the use of bladder antimuscarinics and alpha-blockers is also related to fall risk. They contribute to (or cause) falling through dizziness, somnolence, visual impairment, and orthostatic hypotension while they differ in their side-effect profiles regarding these problems. Falls are common and can cause a remarkable amount of morbidity and mortality. Thus, preventive measures should be taken to lower the risk. If the clinical condition allows, withdrawal of bladder antimuscarinics and alpha-blockers is recommended in fall-prone older adults. There are practical resources and algorithms that guide and assist clinicians in deprescribing these drug groups. CONCLUSIONS The decision to prescribe or deprescribe these treatments in patients at high risk of falls should be individualized. In addition to explicit tools that are helpful for clinical decision-making in (de-)prescribing these drugs, STOPPFall (a recently developed expert-based decision aid specifically aiming to prevent falls) is present to assist prescribers in attaining decisions.

Abstract
Overactive bladder (OAB) is a common and distressing condition which is known to have a significant effect on Health-Related Quality of Life (HRQoL). Whilst all patients complaining of overactive bladder symptoms will, in theory, initially benefit from conservative measures, many will require pharmacological therapy. Antimuscarinics currently remain the most commonly used drugs to treat OAB although compliance and persistence can be poor due to concerns regarding adverse events and lack of efficacy. This review will explore the common management strategies for OAB with a particular focus on patient adherence to therapy including compliance and persistence. The role of antimuscarinics and the B3-agonist, mirabegron, will be considered along with barriers to their efficacy and adoption. For those patients in whom conservative and pharmacological treatment proves ineffective or is unsuitable, the management of refractory OAB will also be considered. In addition, the role of current and future developments will be examined.

Abstract
Objective The treatment effects of vibegron have not previously been evaluated in a prospective, non-interventional observational study of elderly Japanese patients, particularly those ≥80 years old. In addition, no reports have referred to residual urine volume in switching cases. We therefore grouped patients by condition and investigated the treatment effects of vibegron on Overactive Bladder Symptom Score (OABSS), Overactive Bladder Questionnaire Short Form (OAB-q SF), and residual urine volume in each group. Methods This multicenter, prospective, non-interventional, observational study consecutively enrolled OAB patients with total OABSS score ≥3 and OABSS question 3 score ≥2. Sixty-three patients from six centers were recruited. Vibegron 50 mg once daily was administered for 12 weeks as first-line monotherapy (first-line group), monotherapy switching from antimuscarinics or mirabegron due to failure of prior therapy (no washout period), or combination therapy with antimuscarinics (second-line group). OABSS, OAB-q SF, and residual urine volume were collected after 4 and 12 weeks. Adverse events were also recorded at each visit. Results Of the 63 patients registered, 61 were eligible for analysis (first line, n=36; second line, n=25). The OABSS, excluding daytime frequency scores, and OAB-q SF scale showed significant improvement in all conditions. Switching from mirabegron to vibegron significantly reduced residual urine volume. No serious treatment-related adverse events were encountered. Conclusion Vibegron 50 mg once daily significantly improved OABSS and OAB-q SF even in patients ≥80 years old. Notably, switching from mirabegron to vibegron resulted in significant improvements to residual urine volume.

Abstract
PURPOSE OF REVIEW Urinary incontinence (UI) is a common global condition that has been noted to disproportionately affect women. In this review, the authors present discussion of factors contributing to cost of care and various modalities of cost-effective care for UI for female patients. RECENT FINDINGS We found insurance and out-of-pocket (OOP) costs strongly impact of costs for patients. Further, in evaluation of UI, diagnosis can be a costly multi-step process for effective treatment. Treatment can be multimodal, including non-surgical (e.g., pessary, vaginal insert, pelvic floor muscle training, or PFMT), of which PFMT is a cost-effective, effective, and accessible treatment. Pharmacologic management is generally second-line for overactive bladder, but anti-muscarinic drugs and beta-3 agonists are cost-effective depending on willingness-to-pay and the health system in which they are acquired, respectively. Surgical management is considered the most cost-effective treatment as willingness-to-pay increased, with minimally invasive slings being the mainstay. Other relatively novel treatments are also discussed (e.g., EMSELLA) but require further research. Additionally, we discuss systematic barriers in decisions to seek care for urinary incontinence. Urologists are key agents in treating UI for their female patients, and seeking cost-effective options for treatment remains pivotal for quality care.

Abstract
OBJECTIVES Transurethral resection of prostate (TURP) and laser prostate surgery are common surgeries for benign prostate hyperplasia (BPH). We conducted an investigation using hospital database to evaluate the clinical factors associated with post-operative usage of alpha-blockers and antispasmodics. METHODS This study was conducted using retrospective clinical data from the hospital database, which contained newly diagnosed BPH patients between January 2007 and December 2012 who subsequently received prostate surgery. The study end-point was the use of alpha-blockers or antispasmodics for at least 3 months duration after 1 month of surgery. The exclusion criteria was prostate cancer diagnosed before or after the surgery, recent transurethral surgeries, history of open prostatectomy, and history of spinal cord injury. Clinical parameters, including age, body mass index, preoperative prostate specific antigen value, comorbidities, preoperative usage of alpha-blockers, anstispasmodics and 5-alpha reductase inhibitors, surgical methods, resected prostate volume ratios, and preoperative urine flow test results, were evaluated. RESULTS A total of 250 patients receiving prostate surgery in the database and confirmed pathologically benign were included. There was significant association between chronic kidney disease (CKD) and the usage of alpha-blockers after prostate surgery (OR = 1.93, 95% CI 1.04-3.56, p = 0.036). Postoperative antispasmodics usage was significantly associated with preoperative usage of antispasmodics (OR = 2.33, 95% CI 1.02-5.36, p = 0.046) and resected prostate volume ratio (OR = 0.12, 95% CI 0.02-0.63, p = 0.013). CONCLUSIONS BPH patients with underlying CKD were more likely to require alpha-blockers after surgery. In the meantime, BPH patients who required antispasmodics before surgery and who received lower prostate volume resection ratio were more liable to antispasmodics after prostate surgery.

Abstract
PURPOSE OF REVIEW To evaluate recent literature on combination and novel pharmacologic therapies for overactive bladder (OAB). RECENT FINDINGS Combination therapies demonstrating greater efficacy than monotherapy include combination anticholinergics, anticholinergic plus β-3 agonist, and anticholinergic with behavioral modification, percutaneous tibial nerve stimulation, or sacral neuromodulation. Promising novel therapies include new bladder selective anticholinergics, new β-3 agonists, and gabapentin. OAB is a symptom complex caused by dysfunction in the interconnected neural, muscular, and urothelial systems that control micturition. Although several therapeutic targets and treatment options exist, complete resolution is not always achieved, discontinuation rate for medical therapy is high, and few patients subsequently progress to third-line treatment options. Recent literature suggests combination therapy diversifying therapeutic targets is more effective than targeting a single pathway and novel treatments targeting additional pathways have promising results.

Abstract
Background Overactive bladder (OAB) is a common clinical condition for which current drug treatment comprises drugs blocking the cholinergic nerve supply, or augmenting the adrenergic nerve supply, to the detrusor muscle of the urinary bladder. Current treatments have drawbacks, including lack of efficacy and the development of adverse effects in some patients. Hence, new and better drugs for treating OAB will be clinically useful. Objective This review is meant to provide information on drugs currently undergoing preclinical or clinical trials for the treatment of OAB published in journal articles or elsewhere. Methods The cited articles were retrieved from PubMed and Google Scholar from January 1, 1990, to December 31, 2021. The search terms used were contraction or contractility, detrusor, inhibition, isolated or in vitro, in vivo, overactive bladder, and relaxant effect or relaxation. Results There are 4 classes of new drugs under various stages of development for the treatment of OAB. These are drugs acting on the autonomic nerve supply to the detrusor muscle of the urinary bladder that include the anticholinergics tarafenacin and afacifenacin and the β3 adrenoceptor agonists solabegron and ritobegron; drugs acting on ion channels in the detrusor muscle (eg, potassium channel openers and calcium channel blockers), drugs acting on cellular enzymes like phosphodiesterase-5 inhibitors and Rho kinase inhibitors, and drugs acting on miscellaneous targets (eg, pregabalin and trimetazidine). Conclusions Drugs currently used to treat OAB target only the cholinergic and adrenergic cellular signalling pathways. There are many other drugs under trial targeting other cellular pathways that may be useful for treating OAB. Their approval for clinical use might improve the treatment of patients with OAB.
