Study IDST001649
Study TitleUrinary microbiota and metabolome in pediatric vesicoureteral reflux and scarring
Study TypeObservational/cross-sectional
Study SummaryWe enrolled girls and boys aged zero to nine years presenting to a pediatric urologist for recurrent urinary tract infection (UTI) or renal scarring (decreased uptake on a nuclear renal scan) or grade 3-5 vesico ureteral reflux (VUR). Exclusion criteria included other urogenital abnormalities, medical renal disease, immunodeficiency, syndromes associated with VUR, acute UTI, persistent UTI (ongoing positive urine culture 1-3 weeks after completing a treatment course), or global renal atrophy on imaging. At one patient visit, a urine specimen was collected for 16S and metabolomic analysis.

Collection:

Collection ID:CO001719
Collection Summary:Urine was collected from eligible children at clinic visits to a pediatric urologist
Sample Type:Urine
Collection Method:Clean catch or catheterized
Collection Location:Pediatric urology clinic
Collection Frequency:Once
Storage Conditions:-80℃

Treatment:

Treatment ID:TR001739
Treatment Summary:No treatments

Sample Preparation:

Sampleprep ID:SP001732
Sampleprep Summary:100 µL of freshly prepared 1 mg/mL urase solution was added to 100 µL of each of the urine samples then vortexed for 20 seconds and allowed to stand at -20 oC for 1 h. Next, 20 µL of 1 mg/mL of ribitol in water was added to each sample followed by addition of 1 mL of MeOH that was precooled to -20 ºC. The solution was again vortexed for 20 seconds and allowed to stand at -20 ºC for another 2 hours. The samples were centrifuged at 13000g for 15 minutes, and 1 ml of the supernatant from each sample was transferred to an autosampler vial and dried under gaseous nitrogen stream. Additionally, a pooled sample was prepared by combining 200 µL of supernatants from each sample and dried under nitrogen. Dried extracts were stored at -20 C until derivatization.
Processing Storage Conditions:-20℃
Extraction Method:For GCMS-polar analysis samples were extracted with water, containing 1 mg/ml ribitol, and 1 ml methanol.
Extract Enrichment:1 mL each of supernatant was collected from each sample for GCMS-polar analysis.
Extract Storage:-20℃
Sample Resuspension:For GCMS analysis extracts dried under nitrogen flow and storred at -20C then resuspended in 25 μl of pyridine containing 15 mg/ml methoxyamine hydrochloride
Sample Derivatization:GCMS samples were derivatized with 25 μl MSTFA (N-methyl-N-(trimethyl-silyl)trifluoroacetamide) + 1% TMCS (chlorotrimethylsilane)
Sample Spiking:Ribitol was used as internal standard for GCMS-polar analysis.
