Glycosaminoglycan Replacement Therapy with Intravesical Instillations of Combined Hyaluronic Acid and Chondroitin Sulfate in Patients with Recurrent Cystitis, Post-radiation Cystitis and Bladder Pain Syndrome: A Narrative Review.

Abstract
Defects in the glycosaminoglycan layer (GAG) of the bladder mucosa have been identified as a significant contributor to the pathogenesis and clinical progression of chronic inflammatory diseases of the bladder, such as post-radiation cystitis, bladder pain syndrome and recurrent urinary tract infections. This narrative review aims to explore the contemporary evidence on the role of GAG reconstitution with intravesical installations of hyaluronic acid and chondroitin sulfate in the management of those patients, with a goal to provide valuable insights for clinical practice. The reviewed studies consistently demonstrate that GAG reconstitution can result in varying degrees of clinical improvement in patients with post-radiation cystitis, bladder pain syndrome and recurrent urinary tract infections, and is associated with a very favorable safety profile. While the available evidence is growing, its level is still limited, mainly by relatively low number of randomized controlled trials, with small sample sizes. Further research with larger, well-designed trials is needed to solidify the findings and optimize the clinical application of GAG reconstitution.

Abstract
OBJECTIVES To assess uptake and application of the IDEAL principles in original surgical procedure- or device-related clinical research studies, as well as its reported relevance as characterized by secondary publications, editorials and reviews. MATERIALS AND METHODS IDEAL (Idea, Development, Exploration, Assessment, Long-term study) is a framework that provides stage-specific guidance for surgical innovation and represented a major advance towards raising evidential standards. We performed a comprehensive literature search of all urology-related publications citing one or more of seven key publications on IDEAL in The Lancet and BMJ using multiple databases up to 31 December 2017. RESULTS We identified a total of 150 urology-related manuscripts citing IDEAL, of which 83 (55.3%) were original research and 67 (44.7%) were secondary publications. Among the original research articles, 40 (48.2%) did not explicitly apply IDEAL principles or were not surgical innovation studies. The IDEAL phases of the 43 (51.8%) remaining original research studies were IDEAL, in nine (20.9%), 27 (62.8%), four (9.3%), 0 (0%), and three publications (7.0%), respectively. Across IDEAL stages, 30 (75.0%) studies were prospective, 29 (85.3%) reported ethical oversight, and 39 (90.7%) captured treatment-related harms. None of the studies collected information on physician experience. CONCLUSIONS The IDEAL framework has found widespread adoption in the urology literature as witnessed by a large number of original manuscripts and secondary publications citing IDEAL; however, its application is largely limited to the early stages of surgical innovation, frequently with inappropriate and incomplete implementation. Further efforts are needed to guide investigators in the optimal use of the IDEAL framework as it relates to surgical innovation in urology.

The therapeutic approach to different forms of cystitis: impact on public health. Urologia 2017; 84:8-15.

Abstract
Interstitial cystitis/bladder pain syndrome, recurrent urinary tract infections and other forms of cystitis significantly impact the quality of life of patients with chronic bladder disorders and impose a considerable economic burden on health systems. Effective management is essential to provide symptom relief and to reduce the negative impact of chronic bladder disorders. Identifying the appropriate pharmacological or non-pharmacological approach is essential, and there is a growing evidence base for the use of intravesical hyaluronic acid and chondroitin sulfate in several bladder conditions, including recurrent urinary tract infections.

Abstract
This article briefly summarises data published over the last decade which have investigated the concept that intravesical instillation of glycosaminoglycans (GAGs) hyaluronic acid and chondroitin sulfate is able to restore the GAG layer and provide a beneficial effect in protecting the bladder. In the second half of this article, pre-clinical studies which assess the effectiveness of intravesical instillation of Ialuril® after chemical or electromechanical damage to the rat bladder wall are described.

Abstract
Although the pathophysiology of acute chronic cystitis and other 'sensory' disorders, i.e. painful bladder syndrome (PBS) or interstitial cystitis (IC), often remains multifactorial, there is a wide consensus that such clinical conditions may arise from a primary defective urothelium lining or from damaged glycosaminoglycans (GAGs). A 'cascade' of events starting from GAG injury, which fails to heal, may lead to chronic bladder epithelial damage and neurogenic inflammation. To restore the GAG layer is becoming the main aim of new therapies for the treatment of chronic cystitis and PBS/IC. Preliminary experiences with GAG replenishment for different pathological conditions involving the lower urinary tract have been reported. There is a range of commercially available intravesical formulations of these components, alone or in combination. Literature evidence shows that exogenous intravesical hyaluronic acid markedly reduces recurrences of urinary tract infections (UTIs). Patients treated with exogenous GAGs have fewer UTI recurrences, a longer time to recurrence and a greater improvement in quality of life. Exogenous intravesical GAGs have been used for the treatment of PBS/IC. Despite the limitations of most of the studies, findings confirmed the role of combination therapy with hyaluronic acid and chondroitin sulfate as a safe and effective option for the treatment of PBS/IC. To prevent and/or treat radiotherapy and chemotherapy induced cystitis, GAG replenishment therapy has been used showing preliminary encouraging results. The safety profile of exogenous GAGs has been reported to be very favourable, without adverse events of particular significance.

New horizons for GAG therapy in the management of urothelial damage. Urologia 2015; 82 Suppl 3:S10-4.

Abstract
Urothelial defects may manifest as various types of signs of symptoms such as frequency and urgency, haematuria and pain. Both prevention and treatment of urothelial damage is fundamental. Many currently adopted treatments lack robust clinical data and are associated with variability in management strategies. Glycosoaminoglycan (GAG) therapy is one of the most promising therapies in treatment of chemotherapy and radiotherapy-induced urothelium defects, and has been investigated in both animal models and clinical studies.
