RESUMO

BACKGROUND: The prevalence of transthyretin amyloid cardiomyopathy (ATTR-CM) in atrial fibrillation (AF) patients remains unclear. We explored the efficacy of computed tomography-based myocardial extracellular volume (CT-ECV) combined with red flags for the early screening of concealed ATTR-CM in AF patients undergoing catheter ablation. METHODS AND RESULTS: Patients referred for AF ablation at Oita University Hospital were prescreened using the red-flag signs defined by echocardiographic or electrocardiographic findings, medical history, symptoms, and blood biochemical findings. Myocardial CT-ECV was quantified in red flag-positive patients using routine pre-AF ablation planning cardiac CT with the addition of delayed-phase cardiac CT scans. Patients with high (>35%) ECV were evaluated using technetium pyrophosphate (99 mTc-PYP) scintigraphy. A cardiac biopsy was performed during the planned AF ablation procedure if 99 mTc-PYP scintigraphy was positive. Between June 2022 and June 2023, 342 patients were referred for AF ablation. Sixty-seven (19.6%) patients had at least one of the red-flag signs. Myocardial CT-ECV was evaluated in 57 patients because of contraindications to contrast media, revealing that 16 patients had high CT-ECV. Of these, 6 patients showed a positive 99 mTc-PYP study, and 6 patients were subsequently diagnosed with wild-type ATTR-CM via cardiac biopsy and genetic testing. CONCLUSIONS: CT-ECV combined with red flags could contribute to the systematic early screening of concealed ATTR-CM in AF patients undergoing catheter ablation.

RESUMO

Tolvaptan, an oral vasopressin V2 receptor antagonist, reduces renal volume expansion and loss of renal function in patients with autosomal dominant polycystic kidney disease (ADPKD). Data for predictive factors indicating patients more likely to benefit from long-term tolvaptan are lacking. Data were retrospectively collected from 55 patients on tolvaptan for 6 years. Changes in renal function, progression of renal dysfunction (estimated glomerular filtration rate [eGFR], 1-year change in eGFR [ΔeGFR/year]), and renal volume (total kidney volume [TKV], percentage 1-year change in TKV [ΔTKV%/year]) were evaluated at 3-years pre-tolvaptan, at baseline, and at 6 years. In 76.4% of patients, ΔeGFR/year improved at 6 years. The average 6-year ΔeGFR/year (range) minus baseline ΔeGFR/year: 3.024 (-8.77-20.58 mL/min/1.73 m2). The increase in TKV was reduced for the first 3 years. A higher BMI was associated with less of an improvement in ΔeGFR (p = 0.027), and family history was associated with more of an improvement in ΔeGFR (p = 0.044). Hypernatremia was generally mild; 3 patients had moderate-to-severe hyponatremia due to prolonged, excessive water intake in response to water diuresis-a side effect of tolvaptan. Family history of ADPKD and baseline BMI were contributing factors for ΔeGFR/year improvement on tolvaptan. Hyponatremia should be monitored with long-term tolvaptan administration.

RESUMO

BACKGROUND: The outcome of catheter ablation could probably differ among patients with atrial fibrillation (AF), depending on age and AF type. We aimed to investigate the difference in predictors of outcome after catheter ablation for AF among the patient categories divided by age and AF type. METHODS AND RESULTS: A total of 396 patients with AF (mean age 65.69 ± 11.05 years, 111 women [28.0%]) who underwent catheter ablation from January 2018 to December 2019 were retrospectively analyzed. We divided the patients into four categories: patients with paroxysmal AF (PAF) or persistent AF (PeAF) who were 75 years or younger (≤75 years) or older than 75 years (>75 years). Kaplan-Meier survival analysis demonstrated that patients with PAF aged ≤75 years had the lowest AF recurrence among the four groups (log-rank test, p = .0103). In the patients with PAF aged ≤75 years (N = 186, 46.7%), significant factors associated with recurrence were female sex (p = .008) and diabetes (p = .042). In the patients with PeAF aged ≤75 years (N = 142, 35.9%), the only significant factor associated with no recurrence was medication with a renin-angiotensin system inhibitor (p = .044). In the patients with PAF aged >75 years (N = 53, 14.4%), diabetes was significantly associated with AF recurrence (p = .021). No significant parameters were found in the patients with PeAF aged >75 years (N = 15, 4.1%). CONCLUSIONS: Our findings indicate that the risk factors for AF recurrence after catheter ablation differed by age and AF type.

RESUMO

Late-onset hypogonadism is generally treated with testosterone replacement treatment. However, the efficacy rate of treatment for patients with low testosterone is not clear because patients without low testosterone are also treated in real-world clinical settings. This study comprised 110 men with low testosterone concentration of <3.0 ng/mL who underwent testosterone replacement treatment. Physical factors, laboratory and endocrinologic profiles, and scores of several questionnaires were assessed. Testosterone replacement treatment was performed with intramuscular injection of 250 mg of testosterone esters every 2-4 weeks, and efficacy was judged by patient satisfaction. After confirming efficacy, changes in several factors by the treatment were evaluated. Finally, the comparison between evaluation by patient satisfaction and by that with the questionnaires was assessed. Among the 110 patients, 77 (70.0%) were satisfied with the treatment, which was effective in 65.7%, 71.4%, and 73.1% of patients with mental, physical, and sexual dysfunction, respectively. The questionnaire scores including the Aging Males Symptoms rating scale were significantly improved in both the satisfaction and non-satisfaction group. However, no significant differences in the amount of change in questionnaire scores were found for all questionnaire scores improved by testosterone replacement treatment between the groups. Patient satisfaction was not associated with improvement of the Aging Males Symptoms score. Although testosterone replacement treatment was effective for 70.0% of the hypogonadal patients, patient satisfaction did not correlate with improvement of questionnaire scores. We concluded that not only questionnaire results but also patient satisfaction is important when evaluating efficacy in patients undergoing testosterone replacement treatment.

RESUMO

OBJECTIVE: To investigate the relation between serum zinc concentration and several factors, including serum testosterone concentration and the score of questionnaires on sexual function in patients with sexual problems. METHODS: This study comprised 720 men (age, 46.3 [21-83] years) with some kind of sexual problem. Age, scores of the Sexual Health Inventory for Men and the Erection Hardness Score, and endocrinologic data including serum concentrations of testosterone, prostate-specific antigen, and zinc were included in this study. After serum zinc concentration of the men was classified into 5 groups (<70, 70≤ <80, 80≤ <90, 90≤ <100, ≤100 µg/dl), the relation of each parameter with serum zinc concentration was assessed for a trend analysis. Finally, the relation between serum concentrations of zinc and testosterone as well sexual function evaluated by the scores of the questionnaires was investigated. RESULTS: Only serum testosterone concentration (ptrend = 0.028) and serum cortisol concentration (ptrend = 0.003) showed a statistically significant relation to serum zinc concentration by trend analysis. Interestingly, trend analysis between serum concentrations of testosterone and zinc still showed a significant association after adjustment for serum cortisol concentration (ptrend = 0.032). However, no significant association was found in the relation between serum zinc concentration and the scores of the questionnaires after adjustment for serum concentrations of testosterone and cortisol. CONCLUSION: We clearly showed that after adjustment for serum cortisol concentration by trend analysis, serum testosterone concentration decreased as serum zinc concentration decreased, although sexual symptoms were not associated with this decrease.

RESUMO

OBJECTIVES: To clarify factors associated with semen quality and confirm whether there is an association between semen quality and serum zinc concentration. METHODS: A semen test was performed on 217 men just after or just before marriage. Variables assessed in the study were: age; symptomatic scores, including sexual function evaluated using several specific questionnaires; endocrinological profiles, especially follicle-stimulating hormone; and serum zinc concentrations. Based on World Health Organization criteria for assessing sperm quality, semen volume ≥1.5 mL, sperm concentration ≥15 million/mL, or sperm motility rate ≥40%, the men were grouped according to whether they had values below or above these criteria. The two groups were compared with regard to the study variables, and correlation between serum zinc concentration and semen quality was evaluated. Independent predictors for inclusion in the group with values below the criteria were investigated further. RESULTS: Of the 217 men included in the study, 45 (20.7%) were categorized as having values below the World Health Organization criteria. The men in this group were significantly older and had significantly worse sexual function, significantly higher follicle-stimulating hormone levels, and significantly lower serum zinc concentrations, than those in the group with values above the criteria. There was no significant correlation between serum zinc concentration and semen quality. However, the independent predictors for having values below the criteria in binomial logistic regression analysis were follicle-stimulating hormone and serum zinc concentration. CONCLUSION: We suggest that semen analysis may be considered in men with a low level of serum zinc and high level of follicle-stimulating hormone when developing a life plan for fertilization.

RESUMO

OBJECTIVES: To define the characteristics of patients with late-onset hypogonadism based on endocrinological findings. METHODS: We assessed age, body mass index, laboratory/endocrinological profiles and symptom-specific questionnaire scores of 967 men with late-onset hypogonadism symptoms. The patients comprised four groups by testosterone and luteinizing hormone concentrations: normal group, compensated hypogonadism group, primary hypogonadism group and secondary hypogonadism group. We compared characteristics between the normal group and compensated hypogonadism group in men with normal testosterone concentration, and the primary hypogonadism group and secondary hypogonadism group in hypogonadal men after age adjustment. RESULTS: The normal group, compensated hypogonadism group, primary hypogonadism group and secondary hypogonadism group accounted for 83.6%, 3.4%, 0.8% and 12.2% of patients, respectively. Despite age adjustment, serum dehydroepiandrosterone sulfate and insulin-like growth factor 1 concentrations were significantly lower in the compensated hypogonadism group than the normal group. Only the Aging Males' Symptoms scale mental subscore was significantly different. Serum testosterone and dehydroepiandrosterone sulfate concentrations were significantly lower in the primary hypogonadism group than the secondary hypogonadism group. Only the Aging Males' Symptoms scale sexual subscore was significantly different. CONCLUSIONS: Most patients with late-onset hypogonadism symptoms are in the normal group, with secondary hypogonadism being much more frequent than primary hypogonadism. Current symptomatic differences among these groups are minor. Classifying patients by testosterone and luteinizing hormone levels might provide useful information for follow up.

RESUMO

OBJECTIVES: To investigate the prevalence of testicular microlithiasis and the relationship between testicular microlithiasis, semen parameters and endocrinological profiles in healthy newlywed men trying for first-time pregnancy. METHODS: Men visiting Juntendo University Urayasu Hospital, Urayasu, Chiba, Japan, or D Clinic Tokyo, Chiyoda-ku, Tokyo, Japan, for a first-time examination of fertility underwent scrotal examination, semen analysis and blood tests. Testicular volume measured by orchidometer, semen parameters measured by the Makler counting chamber and endocrinological profiles were compared between men with testicular microlithiasis and without testicular microlithiasis. The correlation between sperm concentration and the number of calcifications, and sperm motility and the number of calcifications, were investigated. RESULTS: Of 739 men, 60 (8.1%) were diagnosed as having testicular microlithiasis. Among them, testicular volume, semen volume and motility were lower than those in the men without testicular microlithiasis. Luteinizing hormone and follicle-stimulating hormone levels were higher in those with than those without testicular microlithiasis. The sperm concentration correlated negatively with the number of calcifications. There was no significant correlation between sperm motility and the number of calcifications. CONCLUSION: Herein, we report the prevalence of testicular microlithiasis in healthy newlywed men. Furthermore, our findings suggest that semen parameters in men with severe testicular microlithiasis tend to be worse.

RESUMO

Atrioventricular reciprocating tachycardia (AVRT) and atrioventricular nodal re-entrant tachycardia (AVNRT) can coexist and present unidirectional transition (from AVRT to AVNRT, or from AVNRT to AVRT) in a single patient. Actually, such cases have already been reported previously. However, a case with spontaneous bidirectional transition of both tachycardias during supraventricular tachycardia has never been reported. This article describes a case with spontaneous, mutual, and frequent transition between AVRT and AVNRT.

RESUMO

INTRODUCTION: Cardiac resynchronization therapy (CRT) has been shown to be effective for patients with chronic heart failure; however, the efficacy of CRT in patients with cardiac sarcoidosis (CS) has not been established. METHODS: We compared the outcomes of patients with CS who received CRT to patients with dilated cardiomyopathy (DCM). The incidence of major adverse cerebral and cardiovascular events (MACCE) in 11 consecutive CS patients (8 females; mean age, 66 ± 8.0 years) who received CRT were compared with 29 DCM patients (9 females; mean age, 70 ± 8.9 years). RESULTS: Females and patients with previous right ventricular pacing were largely included in the comparison of CS and DCM patients (P < 0.05 and P < 0.0001, respectively). During the mean follow-up period (465 ± 383 days for CS and 729 ± 393 days for DCM), MACCE were evident in 9 patients (23%); specifically, 5 CS and 4 DCM patients developed MACCE (45% vs. 14%, P < 0.05), respectively. Kaplan-Meier survival analysis demonstrated that CS patients had a higher prevalence of MACCE than DCM patients (log rank = 6.306, P = 0.0120; and Wilcoxon = 7.1333, P = 0.0076). Based on univariate analysis, the etiology of CS was associated with MACCE. CONCLUSION: Our results suggest that the long-term outcome of CRT in patients with CS was very poor compared with DCM patients. Thus, caution should be exercised regarding the indication of CRT in patients with CS.

RESUMO

BACKGROUND: Both the progression of diabetic kidney disease and increased glycemic variability play important roles in the pathogenesis of coronary plaque formation via inflammatory pathways in patients with type 2 diabetes mellitus (T2DM). Therefore we evaluated the role of renal function in the contributory effects of blood glucose fluctuations and blood levels of inflammatory cytokine concentrations on the tissue characteristics of coronary plaques in patients with T2DM. METHODS: We prospectively enrolled 71 T2DM patients (mean age: 68 ± 9, male 79%) with 153 coronary artery lesions. Patients were divided into 2 groups according to their estimated glomerular filtration rate (eGFR) levels: Group 1 (≥ 60 mL/min/1.73 m2, n = 40) and Group 2 (< 60 mL/min/1.73 m2, n = 31). All patients underwent continuous glucose monitoring (CGM) for 120 h and the mean amplitude of glycemic excursions (MAGE) was calculated. Serum tumor necrosis factor (TNF)-α was also measured. In addition, gray-scale coronary intravascular ultrasound (IVUS) and iMap-IVUS were performed in the coronary lesions with < 50% luminal reduction. RESULTS: In Group 1, MAGE correlated with percent lipidic volume (%LV) (r = 0.477, p = 0.002). In this group, stepwise multivariate linear regression analyses showed that only MAGE was independently associated with %LV (ß = 0.477, p = 0.002). In contrast, in Group 2, only serum TNF-α correlated with percent fibrotic volume (%FV) (r = - 0.471, p = 0.007), %LV (r = 0.496, p = 0.005) and percent necrotic volume (%NV) (r = 0.426, p = 0.017). In this group, stepwise multivariate linear regression analyses showed that only serum TNF-α was independently associated with each tissue characteristic (%FV ß = - 0.471 and p = 0.007, %LV ß = 0.496 and p = 0.005, %NV: ß = 0.426 and p = 0.017). CONCLUSIONS: In T2DM patients, the tissue characteristics of coronary plaques were associated with MAGE in patients with eGFR ≥ 60 mL/min/1.73 m2 and with serum TNF-α in those with eGFR < 60 mL/min/1.73 m2.

RESUMO

BACKGROUND: Typical left bundle branch block (LBBB) shows 2 peaks of the R wave, which reflect activation reaching the interventricular septum (R) and posterolateral wall (R') sequentially. OBJECTIVE: The purpose of this study was to investigate the relationship among R-R' interval (RR'), mechanical dyssynchrony, extent of viable myocardium, and long-term outcomes in cardiac resynchronization therapy (CRT) candidates. METHODS: The study enrolled 49 patients (34 men; mean age: 69 ± 11 years) with LBBB who received CRT. The LBBB definition used requires the presence of mid-QRS notching in leads V1, V2, V5, V6, I, and aVL. Baseline evaluations were QRS duration (QRSd) and RR' measured from the 12-lead electrocardiogram; eyeball dyssynchrony (apical rocking and septal flash) and opposing-wall delay by speckle tracking from echocardiography, and extent of viable myocardium assessed by thallium-201 single-photon emission computed tomography. Primary outcomes included the combination of all-cause death and heart failure-related hospitalization. RESULTS: RR' predicted volumetric response better than QRSd (area under the curve 0.73 vs 0.67, respectively). The long RR' group (≥48 ms) revealed more frequent eyeball dyssynchrony and significantly greater radial (SL) and circumferential dyssynchrony (AP and SL) and %viable segment than the short RR' group. In multivariate regression analysis, only RR' ≥48 ms was independently associated with higher event-free survival rates following CRT (hazard ratio 0.21; P = .014). CONCLUSION: These findings suggest that RR' in complete LBBB was associated with mechanical dyssynchrony, extent of viable myocardium, and long-term outcomes following CRT.

RESUMO

BACKGROUND: n-3 polyunsaturated fatty acids (PUFAs) reduce the risk of ischemic heart disease. However, there are few reports of a relationship between n-3 PUFAs and coronary spastic angina (CSA). This study aimed to assess the age-dependent role of serum levels of fatty acid in patients with CSA. METHODS AND RESULTS: We enrolled 406 patients who underwent ergonovine tolerance test (ETT) during coronary angiography for evaluation of CSA. All ETT-positive subjects were diagnosed as having CSA. We categorized the patients by age and results of ETT as follows: (1) young (age ≤ 65 years) CSA-positive (n = 32), (2) young CSA-negative (n = 134), (3) elderly (age > 66 years) CSA-positive (n = 36), and (4) elderly CSA-negative (n = 204) groups. We evaluated the serum levels of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), arachidonic acid, and dihomo-gamma-linolenic acid. In the young groups, the serum levels of EPA (64.3 ±â€¯37.7 µg/mL vs. 49.4 ±â€¯28.8 µg/mL, p = 0.015) and DHA (135.7 ±â€¯47.6 µg/mL vs. 117.4 ±â€¯37.6 µg/mL, p = 0.020) were significantly higher in the CSA-positive group than in the CSA-negative group, respectively. However, this was not the case with elderly groups. In the multivariate analysis in young groups, the serum levels of EPA (p = 0.028) and DHA (p = 0.049) were independently associated with the presence of CSA, respectively. CONCLUSION: Our results suggested that the higher serum levels of EPA and/or DHA might be involved in the pathophysiology of CSA in the young population but not in the elderly population.

RESUMO

Recent clinical evidence has suggested that interatrial septal (IAS) adiposity contributes to atrial fibrillation (AF). The present study aimed to confirm the usefulness of transesophageal echocardiography (TEE) to estimate IAS adiposity in patients with AF. The histological IAS analysis based on autopsy samples sought to clarify characteristics that underlie the contribution of IAS adiposity to AF. The imaging study analyzed the TEE results in patients with AF (n = 184) in comparison with transthoracic echocardiography (TTE) and computed tomography (CT) results. The autopsy study histologically analyzed IAS in subjects with (n = 5) and without (n = 5) history of AF. In the imaging study, the ratio of interatrial septum adipose tissue (IAS-AT) volume per epicardial adipose tissue (EpAT) volume was greater in patients with persistent AF compared (PerAF) to those with paroxysmal AF (PAF). Multivariable analysis revealed that both TEE-assessed IAS thickness and TTE-assessed left atrial dimension were predicted by CT-assessed IAS-AT volume. In the autopsy study, the histologically-assessed IAS section thickness was greater in the AF group than that in the non-AF group and was positively correlated with the IAS-AT area percentage. In addition, the size of adipocytes in IAS-AT was smaller, compared to EpAT and subcutaneous adipose tissue (SAT). IAS-AT infiltrated into the IAS myocardium, as if adipose tissue split the myocardium (designated as myocardial splitting by IAS-AT). The number of island-like myocardium pieces as a result of myocardial splitting by IAS-AT was greater in the AF group than in the non-AF group and was positively correlated with the IAS-AT area percentage. The present imaging study confirmed the usefulness of TEE to estimate IAS adiposity in patients with AF without radiation exposure. The autopsy study suggested that the myocardial splitting by IAS-AT may contribute to atrial cardiomyopathy leading to AF.

RESUMO

OBJECTIVES: To investigate urination parameters measured by toilet uroflowmetry in hospitalized men with nocturia over a 24-hour period to clarify the circadian rhythm of urination. Physicians often encounter male patients with complaints of low maximum flow rate only in the early morning. However, this has not been proved scientifically because most urinary examinations are generally performed for outpatients only during the daytime. METHODS: This retrospective study included 117 hospitalized male patients (age, 68.7 ± 12.8 years). The data of 4689 urinations during their hospital stay were evaluated on the ward by toilet uroflowmetry, which is a toilet-type device that allows patients to urinate as usual. The records including voided volume, maximum flow rate, and voiding time were evaluated as averages of 8 time periods of 3 hours each by generalized linear mixed models with an identity link function to adjust for personal bias. RESULTS: Voided volume after adjustment for age was significantly higher during the nighttime (21:00-06:00) than that in the morning (06:00-09:00) and highest from 00:00-03:00. Interestingly, even after adjustment for both voided volume and age, the maximum flow rate from 06:00-09:00 was the lowest. Voiding time after adjustment for age and voided volume was significantly higher during the nighttime (00:00-06:00) than that from 06:00-09:00. CONCLUSION: We clearly showed the circadian rhythm of urination in a group of hospitalized men with nocturia. Maximum flow rate was lowest in the early morning, including just after waking up.

RESUMO

BACKGROUND: Successful implantation of the WATCHMAN device requires an accurate understanding of left atrial appendage (LAA) anatomy and orifice dimensions. Racial differences are observed in LAA size when comparing Asians with non-Asians. METHODS: A total of 170 patients (123 male, 67.4 ± 9.2 years) with paroxysmal or persistent atrial fibrillation (AF) underwent transesophageal echocardiography before catheter ablation or cardioversion (September 2018 to September 2019). As per the recommendations of the WATCHMAN device, the maximal LAA ostial diameters were measured at multiplane angles of 0°, 45°, 90°, and 135°. RESULTS: The majority of patients (121/170, 71%) had an LAA orifice size within 17-25 mm. Fifteen (8.8%) patients had undersized (< 17 mm) and eight (0.5%) had oversized (> 31 mm) LAA. One patient in this population had no LAA. LAA size was significantly larger in patients with persistent AF than in those with paroxysmal AF (23.3 ± 4.2 mm vs. 20.0 ± 3.0 mm, p < 0.001) and in male patients than in female patients (22.4 ± 4.2 vs. 20.9 ± 3.7 mm, p = 0.03). LAA orifice dimension was significantly correlated with CHADS2 score, the left atrial volume (LAV), E/e', and the left ventricular ejection fraction. Persistent AF, body mass index, and LAV were independently associated with LAA orifice dimension in multivariate analysis. CONCLUSION: This study demonstrated the distribution of LAA orifice dimension in the Japanese AF patients. This finding should be used as a reference to understand the racial characteristics of LAA size for the WATCHMAN procedure.

RESUMO

PURPOSE: Sexuality is very important for men's health. Currently, phosphodiesterase type 5 inhibitors (PDE5i) remain the first-line therapy for erectile dysfunction, and no other oral drugs or drinks are approved and used clinically to treat male libido or orgasm dysfunction. In reference to a pharmaceutical dosage document, growing health consciousness is said to have boosted yearly sales of supplement drinks to more than 170 billion yen (1.58 billion US dollars) in Japan. We have created a supplement drink comprised of testofen, L-citrulline, resveratrol, and caffeine. We hypothesized that our supplement drink would be effective for men with sexual dysfunction, and especially libido dysfunction. MATERIALS AND METHODS: In this study, men with sexual dysfunction received a placebo drink for 14 days or our supplement drink (testofen, 600 mg/d; L-citrulline, 800 mg/d; resveratrol, 300 mg/d; and caffeine, 40 mg/d) for another 14 days separated by a 7-day washout period. Patients continued on-demand use of PDE5i. The International Index of Erectile Function (IIEF) score and adverse events were assessed. RESULTS: Twenty patients aged 30-7 years old were enrolled in and concluded the study with no adverse events experienced. The IIEF domains of desire frequency, erection frequency, erection firmness, erection confidence, intercourse satisfaction, ejaculation frequency, orgasm frequency, and overall satisfaction were significantly improved with our supplement drink. CONCLUSIONS: This is the first study to show that our supplement drink may not only be effective for erection but also for libido, orgasm, and ejaculation.

RESUMO

OBJECTIVE: To investigate the efficacy and safety of vibegron add-on therapy in men with persistent storage symptoms receiving α-1 blockers or PDE5 inhibitor for benign prostatic hyperplasia and then determine the independent factors affecting the efficacy of vibegron. METHODS: Vibegron 50 mg was administered for 12 weeks to 42 patients (72.0 ± 8.2 years) with persistent storage symptoms who had taken α-1 blockers (22 patients) or PDE5 inhibitor (20 patients). The primary endpoint was change in the overactive Bladder (OAB) Symptom Score from baseline to end of treatment. The secondary endpoints were changes in each question of several questionnaires, maximum flow rate and residual urine volume. Finally, independent factors affecting the efficacy of vibegron were investigated. RESULTS: Total OAB Symptom Score was significantly decreased (6.21 ± 3.12 vs 4.38 ± 2.46; P < .001). Although each score of several questionnaires, especially for storage symptoms, improved significantly, no significant improvement was found in stress incontinence, straining, bladder pain and urethral pain in the Core Lower Urinary Tract Symptom score. Maximum flow rate and residual urine volume did not change, and no patient discontinued vibegron because of adverse events. Multiple regression analysis showed that OAB Symptom Score, Core Lower Urinary Tract Symptom score, prostate volume and monotherapy with α-1 blocker were independent factors affecting the efficacy of vibegron. CONCLUSION: Add-on therapy of vibegron to monotherapy with α-1 blockers or PDE5 inhibitor for patients with benign prostatic hyperplasia and persistent storage symptoms was effective and safe.
