Summary
Although clean intermittent catheterization (CIC) remains the mainstay to ensure complete low-pressure bladder emptying in neurogenic bladder (NB) patients, this forms a vehicle for bacterial entry and colonization of the urinary tract, which can lead to recurrent urinary tract infection (RUTI) and renal damage. Up to 25% of NB patients on CIC suffer from RUTI and daily, low-dose antibiotic prophylaxis is widely prescribed to prevent these infections. Unfortunately, this therapeutic option is not evidence-based and can be associated with a higher risk of RUTI secondary to development of antibiotic resistance. In addition, many children suffer from a range of adverse reactions and emergence of drug resistant organisms. Moreover, recent studies have shown that antibiotics cause a major disruption in the human microbiome, potentially leading to long term major problems. Probiotics are live microorganisms, which when administered in adequate amounts confer a health benefit on the host. There is evidence that probiotics restore microbial homeostasis in the vagina, reduce the risk of pathogen ascension into the bladder, and modulate immunity to better protect the host. Probiotic strains, including Lactobacillus rhamnosus GR-1, Lactobacillus reuteri B-54 and RC-14, have been shown to be safe and efficacious in an oral formulation or as a vaginal suppository in improving the microbiota profile of the vagina and decreasing the risk of RUTI. Various mechanisms appear to be involved, including modulating antimicrobial and inflammatory defenses, up-regulating protective mucin production and reducing the pressure on pathogens to acquire antibiotic resistance genes. A randomized trial comparing probiotics to antibiotic prophylaxis in children with vesicoureteric reflux showed equivalent reduction in the incidence of RUTI and development of new renal scarring. In addition, down regulation of inflammatory cytokines can potentially favorably alter bladder function and prevent bladder fibrosis. Investigators at London Health Sciences Centre (LHSC) have the opportunity to acquire clinical data that would strengthen the case for probiotics to be integrated into pediatric urology practice for managing CIC and RUTI. This would be the first such study in pediatric NB patients. The main objective of this study is to determine whether the use of probiotics (lactobacilli) can decrease the impact of adverse side effects and the antibiotic resistance that is seen with the prolonged use of antibiotics for patients with neurogenic bladder conditions.
