Filter by:The Purpose of this study is to evaluate the efficacy and safety of intravenous HRS -8427 in patients with complicated urinary tract infection, including acute pyelonephritis.
The goal of this clinical study is to test NRX101 in participants with complicated urinary tract infections including pyelonephritis. The main questions it aims to answer are: - Does NRX101 help participants resolve UTIs? - Is NRX101 safe for participants with UTIs? Participants will be seen in a doctor's office approximately 6 times to: - Answer a short 10 item questionnaire. - Review of side effects - Urine tests - Blood draw (about 10 ml or 2 teaspoons) - Review of medications - Review any signs or symptoms of UTI - Vital signs and weight (including blood pressure, heart rate, respiratory rate, and temperature) - Review of medical history This is an open-label study of NRX101, which means both you and your doctor know what drug you are taking. After the study is completed, researchers will look at the data to see if NRX101 helps participants with complicated UTI's.
The purpose of the study is to investigate whether the use of gentamicin-based irrigation fluid during ureteroscopy decreases the risk of UTIs and other post-operative infections after surgery.
Double-blind placebo-controlled randomized trial aiming to assess the role of Vitamin C supplementation in the prevention of catheter-associated urinary tract infections in women undergoing elective gynecological surgeries.
The number of care home residents is increasing and urinary tract infections (UTIs) are common amongst this group. Accurate diagnosis of UTI is important because not treating an infection may lead to serious consequences including death. However, giving antibiotic treatment when there isn't an infection causes side effects and antibiotic resistance, making future infections harder to treat. Unfortunately, there are several challenges that mean that it is difficult to diagnose UTI accurately in care home residents. Firstly, UTIs don't always cause clear symptoms for people who live in care homes. They sometimes just cause symptoms like confusion which can have lots of different possible causes. Secondly, it may be hard for people living with dementia to say how they are feeling or to easily provide a urine sample. Thirdly, many people who live in care homes have bacteria present in their urine even when they are well, but this not harmful and does not need treatment. Finally, urine tests that are currently available do not give accurate or quick results. We have thought about some new ways that might help show us if someone in a care home really has a UTI but we don't know yet whether these will work. Our ideas include 1) Working out which symptoms or signs mean a UTI is more likely 2) Detecting new markers of infection in urine samples and 3) Trying out new bedside tests that give rapid results. For this study we plan to recruit 100 care home residents who will be followed up over 6 months. All 100 participants will provide information and a urine sample at the beginning of the study. 25 of these participants will also provide repeated weekly samples for 4 weeks to look at any changes in the urine over time. Additional information and urine samples will be collected if a participant develops a possible UTI during the study and any treatments will be recorded. Our findings will be used to develop a funding application for a larger study aiming to improve the diagnosis of UTI in care home residents.
Urinary tract infections (UTIs) are one of the most common bacterial infections managed in general practice: they are the 2nd site of community-acquired bacterial infection after respiratory infections (4-6 million consultations per year in France). UTIs represent 15% of total antibiotic prescriptions in France. Antibiotics recommended for UTIs, except for cystitis, are considered as "critical" (highly generating bacterial resistances). UTIs are a potential source of antibiotic resistance: often inappropriate antibiotic prescriptions, evolution of the resistance profiles of the bacteria involved, emergence of multi-resistant strains. The first hypothesis is that there are other profiles of clinical UTI situations in general practice than typical cystitis or pyelonephritis, including intermediate forms. The second hypothesis is that these intermediate forms of UTI are subject to longer durations of antibiotherapy, and that probable explanatory factors need to be identified.
Among multidrug-resistant bacteria, Methicillin-resistant Staphylococcus aureus (MRSA) isolates were recognized to be an important mortality factor in hospital infections and a major concern in health-care and community settings . The antibiotic-resistant of S. aureus is extended by various bacterial strategies, including limiting uptake of the drug, alteration of the drugtargets, production of druginactivating enzymes and the activation of efflux pumps that effectively remove antibiotics . Relying on the type of antibiotics, bacteria can apply one or more strategies. Specifically, localization of resistance genes in transferable genetic elements, such as plasmid and transposons , causing Horizontal transfer of resistance genes between bacterial strains . MRSA strains are resistant to nearly all beta-lactam antibiotics by producing an alternative penicillin-binding protein known as PBP2a . This protein is encoded by the mecA gene and has a low affinity to manybeta-lactam antibiotics. Furthermore, these strains often show resistance to a wide range of antibiotics . The use of fluoroquinolone for the effective infectious therapy is limited by presence of fluoroquinolone resistance . There are two mechanisms causing resistance to fluoroquinolone. The first one is attributed to mutations occurring in the quinolone-resistance determining region (QRDR) of topoisomerase IV encoded by grlA/grlB and DNA gyrase encoded by gyrA/gyrB; these mutations decrease the affinity ofthe drug. The other mechanism is mediated by efflux pumps which is less recognized . Recently, several efflux pumps have been identified for S. aureus including efflux pumps encoded by chromosome or plasmids. The efflux pumps norA, norB, norC, mdeA, sepA, mepA, sdrM and lmrS are encoded by chromosome while qacA/B, qacG, qacH, qacJ and smr are plasmid-encoded . Efflux pumps could be specialized for specific substrate or mobilized a wide varieties of different antibiotic classes . Despite, efflux pumps can potentially increase resistance to antibiotics in clinical isolates of S. aureus, few studies have been evaluated the individual and collective participation of the efflux system in resistant isolates . Therefore the aim of the study is to detect ciprofloxacin resistant strains of staphylococcus aureus isolates and to detect efflux pump genes ( norA , norB and norC ) mediating resistance in such strains.
Prospective study aiming at collecting clinical Escherichia coli isolates from patients with recurrent urinary tract infection; samples to be collected during routine procedures.
Urinary tract infection is a common infectious disease in clinic. Although urinary tract infection can be initially diagnosed by clinical sign and symptom, signs and urine routine, the application of appropriate antibiotic therapy depends on the further identification of pathogens. Metagenomic sequencing has been widely used in clinical pathogen diagnosis, especially in difficult infectious diseases. ICompared with tissue samples, cerebrospinal fluid, bronchoalveolar lavage fluid, whole blood and other samples, the application of mNGS in urine samples is relatively limited because incorrect sampling methods before and after collection of urine samples are easy to contaminate the samples and the colonization of distal urethra, periurethral skin and vagina will interfere with the interpretation of reports. Previous small sample studies have shown that the sensitivity of mNGS in urinary tract infection is high, but the specificity is relatively low, and there are many problems such as difficult interpretation of reports and low clinical conformity. This is closely related to the mNGS technology algorithm, such as the inability to eliminate the influence of urinary system background bacteria, and the ambiguity of short sequence alignment, which makes it difficult to distinguish homologous pathogens. In this study, based on the standard mNGS sequencing process, the improved Z value analysis method was used to select strictly enrolled clinical samples and compare them with pathogen culture to observe the clinical value of mNGS with Z value analysis method in the treatment of urinary tract infection.
The study is seeking to understand the needs of patients and healthcare practitioners for an innovation in the way that changes in bladder function are assessed. This information will be used in the design and evaluation of a device, being developed in parallel, that assesses changes to the volume and flow of urine in order to determine changes in bladder function. In order to ensure development is optimal, the principal research objective is therefore to understand the needs of patients and healthcare practitioners (ranging from care home staff and GPs in primary care, to urologists in tertiary referral centres).
