Summary: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a debilitating disease with a negative impact on quality of life. Diagnoses and treatments are still unsatisfactory, calling for new approaches. This study aims to provide a comprehensive overview of IC/BPS research, promoting progress in diagnosis, treatment, and prognosis. The complexity of IC/BPS and emerging evidence call for further studies to optimize management.

Summary: This study investigated the usefulness of urinary biomarkers in assessing bladder condition and histopathology in IC/BPS patients. The results show that urinary biomarker levels are associated with symptoms and pathological manifestations, helpful in identifying HIC and NHIC subtypes, but most biomarkers are not strongly correlated with specific bladder histopathological findings.

Summary: The aim of this study was to investigate the expression levels of sensory receptors, inflammatory proteins, and pro-apoptotic proteins in the urothelium of non-Hunner's interstitial cystitis (NHIC) bladders of patients with different clinical and cystoscopic phenotypes. The study concluded that IC/BPS patients with frequency and bladder pain complaints have higher levels of urothelial sensory receptors, and inflammatory and pro-apoptotic proteins. The expression levels of these sensory receptors, inflammatory proteins, and pro-apoptotic proteins are not significantly different among IC/BPS bladders with different conditions.

Summary: This study used 16S rRNA sequencing and untargeted metabolomics techniques to analyze the urinary microbial and metabolite profiles of IC/BPS patients and healthy controls. The results showed differential genera and metabolites associated with the inflammatory response of IC/BPS, including Lactobacillus as a protective bacterium and Sphingomonas as a pathogenic factor. The metabolite theophylline may also play a role in downregulating the inflammatory response of IC/BPS.

Summary: Activation of TRPV4 can negatively regulate bladder inflammation induced by LPS and alleviate bladder hypersensitivity. This finding may provide new therapeutic targets for refractory bladder pain syndrome.

Summary: The study found that the features of HLs in IC patients were not associated with subjective symptoms, but inflammatory changes in HLs were a predictive factor for IC recurrence and associated with frequent urgency episodes and smaller bladder capacity.

Summary: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic bladder disorder characterized by suprapubic pain and discomfort during bladder filling, accompanied by lower urinary tract symptoms. The diagnosis of IC/BPS is still not standardized, but cystoscopy and bladder biopsy can determine the presence of ulcers. The pathophysiology of IC/BPS may involve chronic inflammation, autoimmune disorders, and other factors. Biomarkers in urine and serum specimens could be useful for the diagnosis of IC/BPS.

Summary: The study found that intravesical PRP injection is effective in relieving symptoms of IC/BPS patients, with slightly lower efficacy after a single high-dose PRP injection compared to four low-dose PRP injections. The addition of components and injection site did not significantly affect therapeutic outcomes.

Summary: This study suggests that daily silodosin can be an effective and well-tolerated treatment for refractory BPS/IC female patients. Additionally, stress coping levels may be associated with symptom improvement.

Summary: Bladder pain syndrome (BPS) is often overlooked in pregnancy, despite being a common symptom. This article reviews the current evidence on the impact of BPS on pregnancy and the available options for diagnosis and management, aiming to improve patient experience and outcomes.

Summary: Inflammatory conditions of the urinary bladder are associated with urothelial damage and loss of function. The purinergic P2X7 receptor plays a role in such inflammatory conditions and may be a new therapeutic target for bladder inflammation.

Summary: This study found that in patients with interstitial cystitis/bladder pain syndrome (IC/BPS), repeated intravesical instillations of Sapylin after botulinum toxin A (BoNT/A) injection can produce significantly better clinical outcomes than BoNT/A alone, with good safety.

Summary: By comparing and analyzing IC/BPS and OAB patients, it was found that IC/BPS patients rated their bladder pain, pressure, discomfort, and urinary urgency almost the same, while OAB patients rated pain, pressure, and discomfort significantly lower than urgency. This suggests that in IC/BPS, it is unclear whether pressure or discomfort provide additional information beyond pain, and discomfort may be confused with urgency in OAB.

Summary: This study demonstrates the involvement of the abnormal activation of the CXCL13/CXCR5 axis in the pathophysiology of interstitial cystitis/bladder pain syndrome (IC/BPS). Blocking the activation of the CXCL13/CXCR5 axis by TAK-779 effectively reduces bladder inflammation and improves bladder function.
