Recurrent urinary tract infections Entry of microorganisms eg, Escherichia coli that are able to invade urothelial cells left vulnerable by increased perme- ability or other deficiency provides a protected niche for the infection to progress [31].

In line with this, and the idea of exogenous GAGs as important in treating bladder infection, Damiano et al conducted a well-controlled clinical trial of intravesical HA-CS in patients with recurrent UTIs [32]. Reproduced with permission from Elsevier [32]. Penetration chronic cystitis urinary constituents into the bladder wall causes C-fiber chronic cystitis, chronic cystitis cell activation, and histamine release.

The resulting smooth muscle contraction, neurogenic inflammation, and hypersensitivity translate into the urinary urgency and frequency and chronic pelvic pain that are characteristic symptoms of several chronic bladder conditions. In an experimental animal model, HA-CS instillations counteracted the increase of micturition frequency and threshold pressure, and they increased the bladder compliance, following urothelial damage induced by protamine sulfate and potas- sium chloride.

The potential role of intravesical HA-CS as GAG replacement therapy in other chronic and challenging bladder conditions, including overactive bladder, calculi, and chronic cystitis cancer, is being investigated. Urothelial damage is the central theme of many chronic bladder pathologies. Intravesical instillation of the sodium hyaluronate 1. Published by Elsevier B. E-mail address: [email protected] E. Chemical cystitis More than half of patients undergoing intravesical chemo- therapy with agents such as epirubicin, mitomycin C, and thiotepa are reported to experience cystitis.

This chemically induced inflammation is another potential therapeutic target for intravesical HA-CS. Providing a protective chronic cystitis prophylatically may mean that patients would be better able to tolerate chemotherapy and complete the required course of therapy [30].

It has recently been shown that the urine of patients with bladder hyperactivity detrusor overactivity contained a lower concentration of GAGs than healthy patients in the control group [34]which may explain the efficacy of HA-CS in patients with this condition, possibly by improving the integrity of the urothelial GAG layer and thus reducing micturition frequency.

Urothelial cancer There is evidence that the implantation and seeding of viable tumor cells influences bladder cancer recurrence [35]and endeavoring to prevent early implantation would appear to be a worthwhile therapeutic focus.

The current clinical approach involves chemotherapy with instillations chronic cystitis cytotoxic agents, and two recent proposals under investigation describe an antiadhesive chronic cystitis [36] and an antiangiogenic strategy.

Providing a more protective barrier or bolstering the GAG layer of the urothelium to prevent implantation of tumor cells is another option with therapeutic potential in recurrent bladder cancer [30]. The concept of GAG chronic cystitis as the basis of many pathologic bladder conditions has not only inspired a new treatment but has modified the clinical concept of bladder disease and the approaches to the resolution of these chronic and challenging conditions [4,30].

Although current data onrecurrentinfectionsare limited, ithas beensuggestedthat approximately 1 in 4 of those individuals will have a recurrence within 6 mo, and of those, 1 in 10 will have a third infection [37].

The standard treatment strategy for bacterial cystitis in the United Kingdom includes lifestyle changes, postcoital antibiotics, and low-dose antibiotic prophylaxis [37]. Although statistics are lacking, it is estimated to affect nearly individuals, and the number of patients requiring attention and treatment for this condition in a large district general hospital in Reading, near London, could amount to nearly patients [37].

Lack of awareness and the often obscure nature of the condition contribute to the delay in diagnosis and treatment, which is estimated to be up to 4 yr. Following lifestyle modifications and conventional and alternative treatments, the general hospital chronic cystitis Reading has also used intravesical therapies for this condition. The following series of patients received the combina- tion of HA-CS, which has recently become available for intravesical treatment at the hospital [37].

The first course of HA-CS was administered weekly for 4 wk, then biweekly for 1 mo 6 units. Maintenance treatment was one instillation per month, and patients were taught to self- treat where possible [37].

Of the 30 patients who were treated with intravesical HA-CS, 13 had recurrent UTIs more than chronic cystitis microbio- logically proven infections in the previous 6 mo despite lifestyle optimization and conservative treatments.

Patients had a mean age of 48 yr, a PUF score of 22, and had had 6. At the end of treatment, 9 of the 13 patients were infection free the longest for 6 mo3 were improved, and 1 discontinued treatment [37].

The longest follow-up was 6 mo, by which time pain scores were less than half the baseline score, and the PUF score was reduced [ Fig. Repeat dosing with HA-CS also improved chronic cystitis compliance, similar to prostatitis discussion forum effect of the active metabolite of fesoterodine in a different model of bladder overactivity in rats [26]. A similar increase in bladder compliance was reported following systemic administration of another antimuscarinic, namely oxybutinin, in normal rats [27].

Moreover, because antimuscarinic efficacy in patients seems to be related to an inhibitory effect on the urothelium, decreasing afferent signaling [28]we can speculate that the increase of bladder compliance observed with intravesical HA-CS in this rat model could be due to an inhibition of bladder afferents, similar to what was observed following systemic oxybutynin in rats [27].

Clinical use of intravesical sodium hyaluronate— chondroitin sulfate A combination of sodium hyaluronate and chondroitin sulfate is commercially available as a ml intravesical instillation containing sodium hyaluronate 1.

HA-CS reduces the production of proinflammatory cytokines, reduces urothelial permeability, and facilitates the repair of the protective GAG layer [30]. It is indicated in a range of clinical conditions that originate from damage to the GAG layer [2,4].

As a consequence of hypersensitivity, there Kapor prosztatitis nonresolved acute trauma, chronic tissue hypoxia, and inflammation, which lead to sensory nerve stimulation [20]. It is hypothesized that the CNS receives an increased afferent barrage from the stimulated peripheral nocicep- tors, triggering central mechanisms that amplify and perpetuate the effect of the peripheral sensory nerve input [21].

All this is considered to lead to the windup phenome- non, which describes profound genetic and phenotypic changes in the CNS, resulting in central sensitization [19]. Early treatment crucial Within 24 h, the stimulated peripheral nociceptors trigger transcriptional factor eg, C-jun, C-fos, and nuclear factor [NF]-kB activation, resulting in neuronal growth.

Chronic inflammation is associated with an increased production of nerve growth factor and glutamate, enhancing the DNA transcription process and resulting in an increased synthe- sis of neuropeptides. These in turn induce neurogenic inflammation, which is mediated by capsaicin-sensitive fibers. Nerve resprouting follows, as an increase in synaptic craniocaudal and latero-lateral connections [5].

It is clear that once these mechanisms are triggered, any intervention is beset with difficulties and a risk of failure because the inflammatory cascade and hypersensitization is a complex process. Early treatment may be crucial to prevent gene activation and to block the hypersensitivity cycle before it gets going [5]. Protecting the urothelium and preventing bladder lining damage would seem like a logical way of averting the inflammatory processes that further injure the lining and lead to chronic bladder pathologies.

Chronic cystitis glycosaminoglycan layer As discussed, urothelial damage is the first step in the cascade of inflammatory processes, which, when triggered, may become chronic. The GAG layer provides the initial barrier for physiologic protection, but once injured or defective, it loses its barrier properties, becomes permeable, and permits the inflammatory and hypersensitization cycle to flourish. Protecting the urothelium or promptly restoring the GAG layer may prevent gene changes in the CNS, which will avert the chronic inflammatory process and pain [5].

An animal model of chronic cystitis functional effects of urothelial damage An experimental animal model of bladder epithelial dysfunction, based on the potassium sensitivity test, was devised to demonstrate the process and consequences of urothelial damage and for the chronic cystitis of treatments to counteract the damage [22,23].

Potassium ions usually present in urine do not affect a healthy bladder lining, but the ions will chronic cystitis and irritate an injured or defective lining [23]. The experimental model used intravesical instillations of protamine sulfate PS and potassium chloride KCl in anesthetized female rats. PS is a high molecular weight protein and increases the permeability of the apical mem- brane of the epithelial cells to cations and anions [24].
