Abstract
Serotonin and interleukin 10 (IL-10) may play a role in gestational diabetes mellitus. Hyperglycemic environment, the detrusor musculature of the bladder and pelvic floor muscles may become damaged, leading to urination problems and urine viscosity in pregnant women with gestational diabetes mellitus and pregnancy-specific urinary incontinence. Urine and blood samples were collected from pregnant women between 24 and 28 weeks of gestation. The serotonin concentration and cytokine IL-10 levels were evaluated in plasma and urine. In the total blood and urine, the viscosity was evaluated in the presence and absence of exogenous serotonin and IL-10. The plasma serotonin levels decreased, while the urine serotonin levels increased in the normoglycemic incontinent (NG-I), hyperglycemic continent (GDM-C), and hyperglycemic incontinent (GDM-I) groups. The IL-10 in the plasma decreased in the GDM-I group and was higher in the urine in the NG-I and GDM-I groups. The blood viscosity was higher, independently of urinary incontinence, in the GDM groups. The serotonin increased the blood viscosity from women with GDM-C and urine in the NG-I, GDM-C, and GDM-I groups. Blood and urine in the presence of IL-10 showed a similar viscosity in all groups studied. Also, no difference was observed in the viscosity in either the blood or urine when in the presence of serotonin and IL-10. These findings suggest that serotonin and IL-10 have the potential to reduce blood viscosity in pregnant women with gestational diabetes and specific urinary incontinence, maintaining values similar to those in normoglycemic women's blood.

Abstract
INTRODUCTION AND HYPOTHESIS Studies within the past decade have suggested associations among composition of the urinary microbiota, local immune responses, and urinary incontinence symptoms. To investigate these relationships, we evaluated the structure of the urinary microbiome, local inflammatory markers, and patient responses prior to and at 6-weeks after treatment with anticholinergic medication for urgency urinary incontinence (UUI). METHODS Using a prospective pilot study, we enrolled women who presented with UUI symptoms and were prescribed treatment with anticholinergics. Catheterized urine samples were collected from participants at their baseline and 6-week follow-up visits for microbiological (standard and 16S rRNA gene phylotyping analyses) and cytokine analysis along with the UDI-6 questionnaire and 2-day bladder diary. RESULTS Patients were Caucasian, post- menopausal, with a median age of 64 and median BMI of 30.1 kg/m2. Among the patients, 75% had UUI symptoms for less than 2 years, but with a frequency of at least a few times a week or every day. Most women were prescribed 10 mg oxybutynin ER daily at enrollment. Patients had varied urinary microbiota by culture and 16S phylotyping, with species of Lactobacillus being the most common, in six samples, in addition to taxa associated with Enterococcus, Staphylococcus, and mixed flora. Cytokine levels showed no differences before and after treatment with anticholinergics, nor correlation with urinary bacteria or microbiome composition. CONCLUSIONS Our pilot study suggests factors in addition to the urinary microbiome and local immune responses may be involved in patients' response to anticholinergics for UUI.

Jhang JF, Jiang YH, Kuo HC. Discriminating Different Bladder and Bladder Outlet Dysfunctions by Urinary Biomarkers in Women with Frequency–Urgency Syndrome. Biomedicines 2023; 11:biomedicines11030673. [PMID: 36979652 PMCID: PMC10045187 DOI: 10.3390/biomedicines11030673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 02/22/2023] [Accepted: 02/22/2023] [Indexed: 02/25/2023] Open
Abstract
Objectives: To investigate the role of urinary biomarkers in discriminating different bladder and bladder outlet dysfunctions in women with frequency–urgency syndrome. Materials and Methods: Urine samples collected from 146 women with frequency–urgency syndrome and 34 controls were investigated. All patients were included in previous clinical trials of functional urology studies and underwent a videourodynamic study. Patients with frequency–urgency syndrome were subdivided into idiopathic detrusor overactivity (IDO), neurogenic detrusor overactivity (NDO), dysfunctional voiding (DV), and hypersensitive bladder (HSB) subgroups. Urine samples were collected before any treatment, and urinary inflammatory proteins (interleukin- (IL-) 1β, IL-2, IL-6, IL-8, tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor (VEGF)), neurogenic proteins (nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and prostaglandin E2 (PGE2)), and oxidative stress biomarkers (8-isoprostane, total antioxidant capacity (TAC), and 8-hydroxydeoxyguanosine (8-OHdG)) were measured and compared between the different OAB subgroups and controls. Results: Of the 146 patients, 31 had IDO, 41 had NDO, 45 had DV, and 29 had HSB. The control group included 34 women. The patients with HSB had lower urinary TAC and IL-2 levels than the controls. The patients with IDO, NDO, and DV had significantly higher urinary TNF-α levels than those with HSB. The patients with IDO and NDO showed an increase in the urinary 8-isoprostane levels, whereas the patients with IDO had higher urinary IL-2, NGF, and BDNF levels than those with NDO. The other urinary inflammatory biomarkers did not show enough significant differences to discriminate between the different bladder and bladder outlet dysfunctions. Conclusions: The urinary levels of inflammatory, neurogenic, and oxidative stress biomarkers varied widely among the patients with bladder and bladder outlet dysfunction. This study’s results provide evidence that women with frequency–urgency syndrome and different urodynamic subtypes have varying bladder inflammation and oxidative stress conditions, which might have an impact on treatment outcomes.

Abstract
IMPORTANCE Women with pelvic organ prolapse (POP) have increased prevalence of overactive bladder (OAB) and the evaluation of urinary biomarkers associated with OAB in the setting of POP is limited. OBJECTIVE The objective is to determine whether associations exist between urinary biomarkers measured before POP surgery with postoperative OAB symptoms. STUDY DESIGN In this prospective cohort study, women with anterior and/or apical POP beyond the hymen undergoing POP surgery were assessed using the OAB Questionnaire Short Form (OAB-q SF) and the Urogenital Distress Inventory 6 (UDI-6) preoperatively and 3 months postoperatively. A first morning voided urine specimen was collected preoperatively and 3 months postoperatively. Urinary biomarkers for inflammation, neuroinflammation, and tissue remodeling were measured. Univariate generalized linear models measured the relationship between biomarkers and symptoms. Between- and within-cohort assessments were made using 2-sample paired and unpaired t tests, respectively. RESULTS Seventy-seven participants with OAB (n = 67, 87.0%) and without OAB (n = 10, 13.0%) were enrolled. Seventy-four participants (96%) completed 3-month follow up. The OAB-q SF and UDI-6 scores significantly improved between preoperative and postoperative measures. Preoperative urinary biomarkers did not demonstrate significant correlations with postoperative OAB-q SF or UDI-6 scores. No significant differences were measured in preoperative biomarkers between patients with and without OAB or when comparing preoperative and postoperative biomarkers in patients with OAB. CONCLUSIONS Urinary biomarkers for tissue remodeling, inflammation, and neuroinflammation were not significantly correlated with OAB symptoms in a population of patients with OAB and POP.

Abstract
Overactive bladder (OAB) is a clinical syndrome defined by urinary urgency, increased daytime urinary frequency and/or nocturia, with or without urinary incontinence, that affects approximately 11% of the western population. OAB is accepted as an idiopathic disorder, and is charactersied clinically in the absence of other organic diseases, including urinary tract infection. Despite this, a growing body of research provides evidence that a significant proportion of OAB patients have active bladder infection. This review discusses the key findings of recent laboratory and clinical studies, providing insight into the relationship between urinary tract infection, bladder inflammation, and the pathophysiology of OAB. We summarise an array of clinical studies that find OAB patients are significantly more likely than control patients to have pathogenic bacteria in their urine and increased bladder inflammation. This review reveals the complex nature of OAB, and highlights key laboratory studies that have begun to unravel how urinary tract infection and bladder inflammation can induce urinary urgency and urinary frequency. The evidence presented in this review supports the concept that urinary tract infection may be an underappreciated contributor to the pathophysiology of some OAB patients.

Abstract
This study investigates the bladder from patients with recurrent urinary tract infection (rUTI) at baseline and after intravesical platelet-rich plasma (PRP) injections. Patients with rUTI who underwent repeated intravesical PRP injections provided bladder and urine specimens at baseline and after treatment. Bladder specimens were investigated with electron microscopy and Western blotting. The urine sample was analyzed with commercially available Milliplex immunoassays. A total of 29 patients were enrolled. At baseline, the rUTI bladders exhibited defects of integrity in umbrella cells, a widened tight junction, and lysed organelles. Intracellular bacterial community incubations in the epithelial cells were also noted. Improvement in bladder defects after PRP injection was noted in 25–42% of patients. Bladder UPK3 expression was significantly lower in the patients with rUTI than in controls. Baseline levels of urinary inflammatory cytokine interleukin (IL)-6, IL-8, and brain-derived neurotrophic factor were higher in the patients with rUTI than in the controls, but there were lower levels of vascular endothelial growth factor and nerve growth factor. In the patients with rUTI who recovered from acute infection, the bladders still had immature urothelium, various ultrastructural defects, and elevated urinary inflammatory cytokines. PRP injection has the potential to promote bladder recovery in some of these patients.

Abstract
Over 50% of women with detrusor overactivity (DO), who do not respond to therapy have been shown to have bacteriuria, which may stimulate the release of inflammatory cytokines than can enhance nerve signalling, leading to symptoms of urgency. This study made use of a consecutive series of urine samples collected from women with refractory DO, who participated in a clinical trial of rotating antibiotic therapy. The aim was to determine the effect of bacteriuria and antibiotic treatment on the levels of urinary cytokines, and to correlate the cytokine concentration with patient outcome measures relating to urgency or urge incontinence. The urinary cytokines chosen were IL-1α, IL-1 receptor antagonist, IL-4, IL-6, IL-8, IL-10, CXCL10 (IP-10), MCP-1 and TNF-α. The presence of bacteriuria stimulated a significant increase in the concentrations of IL-1α (P 0.0216), IL-1 receptor antagonist (P 0.0264), IL-6 (P 0.0003), IL-8 (P 0.0043) and CXCL-10 (P 0.009). Antibiotic treatment significantly attenuated the release of IL-1α (P 0.005), IL-6 (P 0.0027), IL-8 (P 0.0001), IL-10 (P 0.049), and CXCL-10 (P 0.042), i.e. the response to the presence of bacteria was less in the antibiotic treated patients. Across the 26 weeks of the trial, antibiotic treatment reduced the concentration of five of the nine cytokines measured (IL-1α, IL-6, IL-8, IL-10 and CXCL-10); this did not reach significance at every time point. In antibiotic treated patients, the urinary concentration of CXCL-10 correlated positively with four of the six measures of urgency. This study has shown that cytokines associated with activation of the innate immune system (e.g. cytokines chemotactic for or activators of macrophages and neutrophils) are reduced by antibiotic therapy in women with refractory DO. Antibiotic therapy is also associated with symptom improvement in these women, therefore the inflammatory response may have a role in the aetiology of refractory DO.

Abstract
OBJECTIVE This study aimed to determine whether levels of choline (Ch) and acetylcholine (Ach) differ between responders and nonresponders to anticholinergic therapy. METHODS Patients prescribed an anticholinergic were evaluated using the Overactive Bladder Symptom Score; Medical, Epidemiologic and Social Aspects of Aging and Incontinence Questionnaire; and Incontinence Impact Questionnaire-7. A 1-day voiding diary and a urine sample were collected. After treatment for 12 weeks, the questionnaires were administered and 1-day voiding diary was completed. Levels of Ach and Ch were measured by liquid chromatography with tandem mass spectrometry. Subjects were divided into responders and nonresponders. Wilcoxon rank sum test and Fisher exact test were used to express differences between groups. Spearman ρ correlation coefficient was used to determine the relationship between Ach and Ch and symptom severity, patient demographics, and questionnaire scores. RESULTS Thirty-one women were included in the analysis. The treatment response rate was 48.8%. The median age was 67 years (interquartile range, 50-76 years), and median body mass index was 32.3 kg/m2 (27.5-40.6 kg/m2), with 41.2% having an additional complaint of stress incontinence. There were no significant differences in symptom severity or questionnaire scores between groups.The median Ch and Ach levels were higher in responders (28.6 vs 9.2 μL, P = 0.04) and (83.1 vs 18.7 nL, P = 0.02), respectively. Levels of both Ch and Ach had moderate positive correlations with the Medical, Epidemiologic and Social Aspects of Aging and Incontinence Questionnaire urgency urinary incontinence score (ρ = 0.533 [P = 0.002] and ρ = 0.453 [P = 0.01], respectively). CONCLUSION In women with overactive bladder, urinary Ach and Ch levels are higher in responders to anticholinergic therapy compared with nonresponders.

Abstract
The goal of our study was to determine whether GPR55 agonists, O-1602, could reverse the cyclophosphamide (CYP)-induced changes in cystometric and inflammatory parameters, indicative of the development of bladder inflammation and overactivity. If confirmed, the stimulation of novel cannabinoid receptor - GPR55, could be a reasonable strategy as a treatment of CYP-induced haemorrhagic cystitis. The experiments were conducted in female Wistar rats. Based on the methodology of our published studies on CYP-induced heamorrhagic cystitis we performed experiments after administration of CYP, O-1602 or CYP plus O-1602. These included surgical procedures, conscious cystometry, measurements of bladder oedema and urothelium thickness using the Evans Blue dye leakage technique, as well as biochemical analyses with particular ELISA kits. O-1602 ameliorated the symptoms of CYP-induced detrusor overactivity leading to an increase in voided volume (0.59 vs. 0.93 ml), and lowering the detrusor overactivity index (703 vs. 115 cm H2O/ml). Intravenous administration of the GPR55 agonist to animals that received CYP significantly decreased Evans Blue extravasation and increased urothelium thickness. O-1602 also reversed the pro-inflammatory activity of CYP by restoring concentrations of brain-derived neurotrophic factor, nerve growth factor, calcitonin gene related peptide, interleukin 1-beta, interleukin-6, tumour necrosis factor alpha, malondialdehyde, nitrotyrosine, occludin, and organic cation transporter 3. GPR55 agonist, O-1602, represents a novel class of uroprotective agents, targeting the inflammatory basis of cystitis. To our knowledge, this is the first paper proposing O-1602 agent, as a candidate for future studies in the treatment of CYP-induced cystitis.

Abstract
Changes in urinary bladder function and somatic sensation may be mediated, in part, by inflammatory changes in the urinary bladder including the expression of chemokines. Male and female C57BL/6 mice were treated with cyclophosphamide (CYP; 75 mg/kg, 200 mg/kg, i.p.) to induce bladder inflammation (4 h, 48 h, chronic). We characterized the expression of CXC chemokines (CXCL9, CXCL10 and CXCL11) in the urinary bladder and determined the effects of blockade of their common receptor, CXCR3, at the level urinary bladder on bladder function and somatic (hindpaw and pelvic) sensation. qRT-PCR and Enzyme-Linked Immunoassays (ELISAs) were used to determine mRNA and protein expression of CXCL9, CXCL10 and CXCL11 in urothelium and detrusor. In urothelium of female mice treated with CYP, CXCL9 and CXCL10 mRNA significantly (p ≤ 0.01) increased with CYP treatment whereas CXC mRNA expression in the detrusor exhibited both increases and decreases in expression with CYP treatment. CXC mRNA expression urothelium and detrusor of male mice was more variable with both significant (p ≤ 0.01) increases and decreases in expression depending on the specific CXC chemokine and CYP treatment. CXCL9 and CXCL10 protein expression was significantly (p ≤ 0.01) increased in the urinary bladder with 4 h CYP treatment in female mice whereas CXC protein expression in the urinary bladder of male mice did not exhibit an overall change in expression. CXCR3 blockade with intravesical instillation of AMG487 (5 mg/kg) significantly (p ≤ 0.01) increased bladder capacity, reduced voiding frequency and reduced non-voiding contractions in female mice treated with CYP (4 h, 48 h). CXCR3 blockade also reduced (p ≤ 0.01) hindpaw and pelvic sensitivity in female mice treated with CYP (4 h, 48 h). CXC chemokines may be novel targets for treating urinary bladder dysfunction and somatic sensitization resulting from urinary bladder inflammation.
