Background: Survival in Granzyme A gene (gzmA) knocked-out mice was significantly longer than in wild-type mice in a murine peritonitis model (cecal ligation puncture). Hypothesis: GZM A has a pathogenic role in sepsis in humans and gzmA polymorphisms can help to predict the risk of sepsis among patients with systemic infections (E. coli bacteremic urinary tract infections). Objectives: 1. To assess the correlation between GZM A serum levels and systemic inflammatory response in a human model of infection/sepsis (E. coli bacteremic UTI) 2. To characterize gzmA polymorphisms among patients with E. coli bacteremic UTI 3. To determine GZM A serum kinetics among patients with E. coli bacteremic UTI 4. To characterize E. coli strains causing bacteremic UTI: antimicrobial phenotype and virulence factors ("virulome"). Methods: - Design and setting: Prospective nested case-control study - Study population: consecutive adult patients with bacteremic urinary tract infections (UTIs) caused by E. coli - Exclusion criteria: Patients with conditions that significantly compromise immune status or patients exposed to urologic procedures - Estimated sample size: 50 patients with a sepsis/ non sepsis 1:1 ratio. Septic and non septic patients will be matched on gender, age (+/- 10 years), comorbidity (Charlson score +/-1), time symptom onset to blood culture (+/- 24h) - Measurements: GZM A serum levels will be determined on day 0, day 2-3, day 30. GZM A kinetics, gzmA polymorphisms (whole exome sequencing).Whole genome sequencing of E. coli isolates retrieved from blood cultures will be performed. - Analysis: Association between GZM A levels and gzmA polymorphisms and sepsis will be analyzed adjusting for patient, infection and microorganism-related factors (multivariate analysis).
In post-menopausal women, the condition atrophic vaginitis results from the loss of oestrogen and is characterised by dyspareunia (pain during intercourse), vaginal dryness, and vaginal irritation. It is often diagnosed alongside recurrent urinary tract infections (rUTIs) and may increase susceptibility to rUTI. Topical vaginal oestrogen can be used to re-condition the vaginal epithelium and also reduces the incidence of rUTIs. However, patients often express concerns about using oestrogen, a hormonal treatment. Studies also report side-effects including vaginal bleeding, discharge, burning and itching that underpin significant (28%) drop-out rates. Hence, alternative non-hormonal, non-antibiotic based therapies that treat the vaginal atrophy, but also reduce the incidence of rUTI are needed. Recurrent UTI in adult women is common. Bacteria from the gut can colonise the vulvar epithelia and then the bladder, causing uncomfortable urinary symptoms (cystitis). The lifetime risk of a UTI is around 40% in adult women which increases in post-menopausal women. Annually, UTI incidence is 3%. Of those affected, 5% will suffer rUTI, rising to 13% in the over 60 population. This equates to over 300,000 of the adult female UK population annually affected by rUTI. The most frequent treatment for rUTIs is low dose antibiotics, but this treatment causes the bacteria carried by such women to become antibiotic resistant, which exacerbates the clinical problem. The prevalence of antimicrobial multi-resistance within post-menopausal women suffering from rUTI is around 25% and was shown to rise to more than 80% following prolonged antibiotics. These data support the use of non-antibiotic treatment strategies that prevent rUTI and the emergence of drug resistant micro-organisms. This study will compare two groups with differing treatment strategies. One group will be primarily treated for atrophic vaginitis with topical vaginal hyaluronate and the other will be primarily treated for their recurrent UTI with intravesical hyaluronate.
The purpose of this study is to determine whether a tailored multifaceted antibiotic stewardship intervention reduces antibiotic use for urinary tract infections in residential care homes and nursing homes attended by general practitioners. This will be evaluated in a pragmatic cluster randomised controlled trial using a modified community-based participatory action research approach.
The objectives of the Clinical Validation Through Analytical Study With Urine Samples to Compare the Effectiveness and Security of an Intelligent Device are: 1.To evaluate the performance of S-There Device in comparison to the golden standard used in the lab.
The purpose of this study is to assess the safety and feasibility of administering glycosaminoglycan (GAG) therapy, iAluRil®, intravesically in individuals with acute spinal cord injury (SCI), commencing within the first ten days of injury, to prevent early urinary tract infections.
The study will explore the impact of a nurse-led bundled antimicrobial stewardship intervention on the appropriateness of antimicrobial use in residential aged care facilities. The intervention will be assessed in a stepped-wedge cluster randomised controlled trial across 14 residential aged care facilities over an 18-month period.
In this protocol, investigators are examining the ability for a novel multiplex PCR assay with mixed floral antibiotic resistance profiling is safe and increases effective treatment for urinary tract infections in a urology clinic over traditional culture methods alone and decreases retreatment rates in this population.
Participants will undergo daily gentamicin bladder instillations to determine if its use will reduce the rate of symptomatic urinary tract infections (UTIs) as well as the use of oral and intravenous antibiotics in adults with chronic spinal cord injury (SCI) who have recurrent UTIs. Participants are randomized into one of three groups: 1) Gentamicin and saline instillation 2) Saline only instillation 3) Standard of care, no instillation.
Urinary infections are at the origin of many emergency department consultations and antibiotic prescriptions. Increase of bacteria resistance to antibiotics is promoted by an inappropriate use of those antibiotics but initial prescription in emergency departments is complicated by brief clinical examinations, unavailable sampling results and risks of multi-resistant bacteria. Large diffusion of new recommendations for urinary infection management should improve the quality of initial antibiotic prescription. However emergency physicians have no knowledge of the reassessment of antibiotherapy 48 to 72 hours after initial prescription by general practitioners which is a quality criterion of good antibiotic use. The main purpose of this study is to estimate the reassessment rate by general practitioners of the urinary infection antibiotherapies prescribed in emergency departments. This will allow assessing the quality of initial antibiotic prescription and help to improve practices.
