|Lower Urinary Tract Symptoms||Drug: Lactobacillus rhamnosus GG||Phase 2|
Lower urinary symptoms are a common issue for individuals with neurogenic bladder, commonly occurring in the Spina bifida and Spinal Cord Injury population. In this study, probiotics will be introduced into the bladder to prevent UTIs. Introduction of probiotics will be determined by a validated symptom questionnaire (USQ-NB) and protocol (SMP-PRO).
This study will estimate the strength of the associations between successful implementation of the probiotic self-management program (USQ-NB and SMP-PRO) and urinary symptoms, bladder inflammation, and the urine microbiome. Investigators will conduct an 18-month study in which each participant will serve as his/her own control through 3 phases of study: 6-months usual care (baseline), 6-months probiotic intervention, and 6-months follow-up.
Participants will complete the Urinary Symptom Questionnaire weekly. After 6 months of baseline data collection, participants will receive the Lactobacillus (Culturelle GG, 20 billion live organisms for adults and 10 billion live organisms for children <18 years of age), will be instructed on preparation and intravesicular instillation of the Lactobacillus, and will have a tutorial with a fellow consumer on use of the patient-initiated protocol. The protocol and Lactobacillus bladder instillation instructions (including a step-by-step video) will be available on the study website for 24/7 access and written instructions will be provided at the time of instruction.
For the intravesicular Lactobacillus instillation, participants will be instructed to mix the contents into sterile saline. After mixing, participants will draw up the liquid Lactobacillus mixture into a 60cc catheter tip syringe and instill via the intermittent catheter after fully emptying the bladder. Participants will be instructed not to catheterize for at least 4 hours after the bladder instillation. Participants will receive 10 Culturelle GG at the beginning of the treatment phase. At the end of each month, the coordinator or RA will ask how many remaining tablets the participant has, and if needed dispense the next supply of 10 tablets. Participants will be instructed to complete the USQ-NB weekly.
If/when urinary symptoms occur, subjects will be instructed to follow the protocol to determine whether to initiate intravesicular Lactobacillus instillation or be evaluated by a physician. The self-management protocol will also direct them to discontinue Lactobacillus instillation or be evaluated by a physician if symptoms remit, persist (after 2 instillations), or worsen. The maximum number of instillations is 2 over 28 hours. If participants are directed by the self-management protocol to seek medical attention or s/he feels the need for medical evaluation, s/he will be advised to obtain care as they typically would by their health care provider. Participants will be supplied with letters to be brought to their health care provider notifying them of the study and requesting sharing of urinalysis and urine culture results with the research team. A verified UTI will include those that resulted in antibiotic treatment by a health care professional. An additional urine sample for metagenomics will either be left with the health care provider for pick up by the research team, brought to the research site, or obtained by the RA at a mutually convenient site.
After completion of the 6-month patient-initiated, self-management protocol intervention period, participants will monitor symptoms weekly using the USQ-NB for the final 6-month phase of the 18-month study.

Lactobacillus rhamnosus GG
Drug: Lactobacillus rhamnosus GG
For the intravesicular Lactobacillus instillation, participants will be instructed to mix the contents of 1 Lactobacillus capsule into 45 cc sterile 0.9% saline.5,6 After mixing, participants will draw up the 45 cc of the liquid Lactobacillus mixture into a 60cc catheter tip syringe and instill via the intermittent catheter after the last catheterization prior to going to bed. Participants will receive 10 Lactobacillus GG tabs at the beginning of treatment phase. At the end of each month, the coordinator or RA will ask how many remaining tablets the participant has, and if needed dispense the next supply of 10 tablets Participants will be instructed to complete the USQ-NB weekly.
Other Name: Culturelle
- Urine Symptom Questionnaire [ Time Frame: Completed Weekly throughout the study (up to 78 weeks) ]A preliminary urinary symptom questionnaire has been developed with consumer input based on the most common typical and SCI-specific urinary symptoms.
- Health History Questionnaire [ Time Frame: Collected at Baseline ]After subjects give consent, a brief medical history will be conducted using a structured questionnaire including demographic information, genitourinary history, and current medications
- Patient satisfaction [ Time Frame: End of each phase (weeks 26, 52, and 78) ]Investigators have developed a simple four item patient satisfaction "survey" that will be requested at the end of each phase of the study. Participants will be asked to rate their satisfaction, thinking only about the preceding time period, with changes in the frequency of their symptoms; the amelioration of the severity of their symptoms; and changes in the impact of their symptoms.
- Urine Acquisition [ Time Frame: Up to 18 months: collected at Baseline, two times when study subject experiences urinary symptoms, and follow-up after either lactobacillus treatment or antibiotics (not specific time points), and week 12 of follow-up phase ]A 50-100 ml urine sample will be collected from each subject for (1) urinalysis and cultivation, and (2) urine microbiome by SMRT sequencing. Urine will be collected from a new, unused intermittent catheter.
- Urinalysis [ Time Frame: Up to 18 months: collected at Baseline, two times when study subject experiences urinary symptoms, and follow-up after either lactobacillus treatment or antibiotics (not specific time points), and week 12 of follow-up phase ]Urine samples will be assessed utilizing standard clinical microbiology semiquantitative chemical testing using commercial disposable test strips for glucose, bilirubin, ketone, specific gravity, blood pH, protein, urobilinogen, nitrite, and leukocyte esterase. After centrifuging for 5 minutes, microscopic examination for and quantification of WBCs, RBCs, epithelial cells, yeast, bacteria, Trichomonas vaginalis, sperm cells, mucous filaments and crystals will be performed using standard microbial techniques.
- Urine Culture [ Time Frame: Up to 18 months: collected at Baseline, two times when study subject experiences urinary symptoms, and follow-up after either lactobacillus treatment or antibiotics (not specific time points), and week 12 of follow-up phase ]Standard urine culture microbiology will be performed. A measured amount is inoculated to each of the appropriate media. A calibrated loop designed to deliver a known volume (0.0 I ml per loopful) of urine is used. The sample will be mixed the thoroughly and the top of the container removed. A calibrated wire-inoculating loop is flamed and allowed to cool without coming in contact with any surface. The sterile loop is inserted into the urine sample vertically and urine is allowed to adhere to the loop. The loopful of urine is inoculated over MacConkey agar plates using standard methods. Similarly, a second loopful is collected and inoculated on a blood agar plate. The plates are incubated aerobically at 35-37oC for at least 24 hours. The colonies and colony forming units (CFUs) are counted by multiplying with 100 (since 0.01 ml loop was used).
- Microbiome SMRT Sequencing [ Time Frame: Up to 18 months: collected at Baseline, two times when study subject experiences urinary symptoms, and follow-up after either lactobacillus treatment or antibiotics (not specific time points), and week 12 of follow-up phase ]Thawed urine samples will be clarified by low-speed centrifugation and bacterial genomic DNA will be isolated from pelleted bacteria using a DNeasy tissue extraction kit (Qiagen) according to manufacturer's instruction. 16S rRNA genes will be amplified. These amplification products will be used for sequencing template preparation using DNA Template Prep Kit 2.0 (Pacific Biosciences) followed by DNA Polymerase binding (DNA Polymerase Binding Kit P4, Pacific Biosciences). Sequenced rRNA genes will be analyzed and classified using Pathoscope.
