Plain English Summary
Background and study aims
Multiple Sclerosis (MS) is an autoimmune inflammatory disease that causes damage to the myelin sheaths of the nerves in the central nervous system. MS is commonly diagnosed between the ages of 20-40 and is three times more likely to affect women than men. Most (80%) of MS patients report lower urinary tract symptoms (LUTS). The most common is urge incontinence (a sudden need to use the toilet followed immediately by urinating), but MS sufferers also report urinary tract infections(UTIs).UTIs have been associated with relapses and progression of MS. UTIs can made the neurological symptoms in MS worse whilst high-dose steroid treatment of acute neurological worsening may lead to diagnosis of an UTI that had not previously been identified. Half of the women with MS will have at least one episode of UTI requiring antibiotic therapy during their lifetime. Moreover, 25-35% of initial UTI episodes are followed by a recurrent infection within 3-6 months. The chances of someone developing a UTI is complex and depends on genetic, biologic, and behavioural factors. Among the recognised factors, the interaction between the bacteria and the epithelial cells lining the bladder wall is thought to be important. Damage to a layer lining the bladder (the glycosaminoglycan or GAG layer) may expose epithelial cells to urine, which, in turn, may lead to infection. Various approaches have been developed towards a reversal of the damage and a reconstruction of the GAG layer, including the use of heparin, oral pentosan polysulphate, and hyaluronic acid (HA). HA is a major mucopolysaccharide widely found in the connective, epithelial, and neural tissues. Chondroitin sulphate (CS) is also an important structural component for bladder mucosal integrity. Both HA and CS are known to work well in treating cystitis (bladder infection). This suggests that a similar therapeutic approach might be beneficial for treating recurrent UTI. We want to investigate the performance and tolerability of oral administration of combined HA andCS in reducing UTIs and improving the quality of life (QoL) in female patients with multiple sclerosis and a history of recurrent UTIs.
Who can participate?
Women (over 18) with MS that have had at least three UTIs
What does the study involve?
Participants first go to a screening visit to see whether they are eligible. This involves assessment of age, clinical history, symptoms and quality of life. Participants are then randomly allocated into one of two groups. Those in group 1 are given one combined HA and CS capsule twice a day, every day, for 2 weeks and then once a day, every day, for two months. Those in group 2 are given a placebo twice a day, every day, for 2 weeks and then once a day, every day, for two months. UTI assessments are made for all participants before they start the treatment and then after 4,8 and, finally, 12 months.

Primary outcome measures
Mean rate of UTI episodes per patient per year. A UTI episode was defined in the form of significant bacteriuria as >10000 CFU/ml of midstream urine with clinical symptoms.
Assessments measured at baseline and after 4,8 and 12 months.
Secondary outcome measures
1. Time to UTI recurrence (defined as the time relapsed between the first administration and the first recurring infection)
2. Variation in void frequency and volume
3. Impact of therapy on QoL
4. Rate of adverse events
Assessments measured at baseline and after 4,8 and 12 months.

Target number of participants
Efficacy data were based both on previously reported data and our own experience in daily clinical practice at our institution. Using type I error and a power of 5% and 80%, respectively, and by proposing the hypothesis that HA would be able to induce a 70% decrease of UTI rate per patient per year, it was calculated that 30 subjects per group were necessary to detect this difference
Participant exclusion criteria
1. Age >80 years
2. UTIs in the previous year < 3
3. Concomitant UTI at the beginning of the study or ongoing prophylactic antibiotic treatment
4. Known neoplasia, urinary stone or abnormality of the urinary tract
5. Chronic kidney disease, diabetes mellitus, use of spermicides or intrauterine devices
