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 .
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 .
Reproduced with permission from Elsevier . Penetration of urinary constituents into the bladder wall causes C-fiber activation, mast 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 urothelial 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 Prostatitis Canda epirubicin, Prostatitis Canda C, and thiotepa are reported to experience cystitis. This chemically induced inflammation is another potential therapeutic target for intravesical HA-CS.
Providing a protective layer prophylatically may mean that patients would be better able to tolerate chemotherapy and complete the required course Prostatitis Canda therapy .
It has recently been shown that the urine Lesz a prosztatitis patients with bladder hyperactivity detrusor overactivity contained a lower concentration of GAGs than healthy patients in the control group 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 Prostatitis Canda of viable tumor cells influences bladder cancer recurrence and endeavoring to prevent early implantation would appear to be a worthwhile therapeutic focus.
The current clinical approach involves chemotherapy with instillations of cytotoxic agents, and two recent proposals Anatómiai nyereg prosztatitis investigation describe an antiadhesive application  and an antiangiogenic strategy. Providing a Prostatitis Canda 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 .
The concept of GAG involvement 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 A prosztatitis fájdalom jelei 6 mo, and of those, 1 in 10 will have a third infection .
The standard treatment strategy for bacterial cystitis in the United Kingdom includes lifestyle changes, postcoital antibiotics, and low-dose antibiotic prophylaxis . 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, Prostatitis Canda amount to nearly patients .
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 in Reading has also used intravesical therapies for this condition.
The following series of patients received the combina- tion of HA-CS, which has recently Prostatitis Canda available for intravesical treatment at the hospital . 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 .
Of the 30 patients who were treated with intravesical HA-CS, 13 had recurrent UTIs more than three 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 . 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 [ Prostatitis Canda.
Repeat dosing with HA-CS also improved bladder compliance, similar to the effect of the active metabolite of fesoterodine in a different model of bladder overactivity in rats .

A similar increase in bladder compliance was reported following systemic administration of another antimuscarinic, namely oxybutinin, in normal rats Prostatitis Canda.
Moreover, because antimuscarinic efficacy in patients seems to be related to an inhibitory effect on the urothelium, decreasing afferent signaling 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 .

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 .
It is indicated in a range of clinical conditions that originate from damage to the Prostatitis Canda layer [2,4]. As a consequence of hypersensitivity, there is nonresolved acute trauma, chronic tissue hypoxia, and inflammation, which lead to sensory nerve stimulation .
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 .
All this is considered to lead Prostatitis Canda the windup phenome- non, which describes profound genetic and phenotypic changes in the CNS, resulting in central sensitization . 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 .

It is clear that once these mechanisms are triggered, any intervention is beset Prostatitis Canda 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 .
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 Prostatitis Canda.
Target 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.
