Active clinical trials for "Bacteriuria"

This study is evaluating whether screening of a pregnant woman for asymptomatic bacteriuria in each trimester for early detection and treatment of bacteriuria will reduce the incidence of preterm birth in Harare.

Urinary tract infections (UTI) are the most common complications after kidney transplantation. Most series have reported incidence between 20 to 50% during the first year. In the most recent report from our center the incidence was 36.6% during the first 6 months after transplantation. The clinical consequence in the graft survival and the association with immunological rejection has not been well defined. Nevertheless, the association of UTI with high rate of hospitalization and their costs are widely recognized. There is paucity of trials, specially randomized and controlled, comparing antibiotic prophylaxis in this group of patients. In a recently published metaanalysis Green et al. (Transpl Infect Dis. 2011 Oct;13(5):441-7) found only 6 clinical trials well designed, the conclusion was that antibiotic prophylaxis reduced the incidence of UTI and the risk of sepsis. Based in this information, the KDIGO guidelines in transplantation recommend the prophylaxis for UTI with sulfamethoxazole-trimethoprim (SMT). Nevertheless, the rate of bacterial resistance to SMT has been reported above 50% in almost all the series. Fosfomycin-trometamol (FT) is a wall antibiotic (piruvil-tranferase inhibitor) that has shown a good bioavailability, especially in the urinary tract. It has shown a wide antibacterial spectrum, but the important target seems to be enteric bacilli particularly Escherichia coli (the most prevalent cause of UTI). FT has also shown a very good activity against E. coli producer of Extended Spectrum Betalactamases. Recently, the rate of these multi-drug resistant bacteria has increased in our center as evidence of worldwide distribution. In addition, the rate of FT resistance has been stable during the last years (<3%). This phenomenon could be explained because of the properties of this antibiotic, the most important one seems to be related with the unique mechanism of action and the lack to propagate the mechanisms of resistance at least in E. coli. There is only one clinical trial (randomized and controlled), which compared FT with placebo in UTI prophylaxis; 317 women with recurrent UTI (three by year) were included. They found rates of 0.14 and 2.9 episodes/patient/year, respectively (p<0.001). Furthermore, there was no FT resistance during the follow up. Our hypothesis is that in the first six months after kidney transplantation, UTI prophylaxis with FT will show greater efficacy in comparison with SMT. Considering the incidence of UTI in our center (36.6%) and the rate of UTI in the unique trial of prophylaxis with FT (14%), 65 patients will be needed by group of treatment to demonstrate a difference of 22% in the incidence of UTI, with a power of 80% and confidence level of 95%. The primary outcome is the incidence and rate of UTI during the first six months after kidney transplantation. The secondary outcomes are, the hospitalization rate, antibiotic resistance rate, rejections and titer and number of de novo donor specific antibodies. The investigators propose a randomized, double blind, placebo controlled trial to compare FT with SMT in the efficacy and safety to prevent UTI during the first six months after kidney transplantation. The investigators will include patients from two tertiary-care transplant centers. Recruiting and the randomization will be carried out separately by center and gender (because female patients have a greater risk of UTI). The medical visits will be scheduled monthly and include general laboratory, urine culture and information gathering about antibiotic side effects as well as adherence. Rejection rate and the number and titers of de novo donor specific antibodies (secondary outcome) will be obtained according to the standard of care of the institutional kidney transplantation follow up. These include kidney biopsy at days 0 and 90 after transplantation, as well as determination of donor specific antibodies after sixth months of follow up. Graft biopsy is also performed whenever graft dysfunction exists in the absence of an identifiable cause (infection, urinary graft obstruction).

Urinary-tract infection (UTI) is the most common type of hospital-acquired infection (30% of all). The purpose of this study is to determine whether antibiotic prophylaxis for urinary catheter removal is useful at preventing catheter-associated urinary-tract infection.

A clinical controlled, randomized and double blind trial that included adult patients (≥18 years) receiving kidney transplantation (KT) at the INCMNSZ. The intervention group will receive disodium fosfomycin 4 g intravenously in three moments: preoperative of transplant surgery, prior to removal of the urinary catheter and finally prior to removal of ureteral catheter. The control group will receive placebo in the same moments. Both groups will receive prophylaxis standard for urinary tract infection (UTI), with trimethoprim/sulfamethoxazole 160/800 mg per day. This prophylaxis will be administered once the estimated glomerular filtration rate is greater than 30 mL/min/1.73m2. The primary objective is to compare the average number of episodes of UTI´s and asymptomatic bacteriuria in both groups after 7 weeks of follow-up. The secondary objectives are to know the incidence of asymptomatic bacteriuria, the incidence of hospitalizations for IVU, the days of hospital stay, the pattern of bacterial resistance, the safety of disodium fosfomycin, and assessment of the function of the graft and rejection rate.

The purpose of this study is to determine the amount of cranberry juice that is most effective in preventing a condition in pregnant women that often leads to urinary tract infections (UTIs).

Urinary tract infection (UTI) is the most common infection in nursing home residents, and bacteriuria is the greatest trigger for antimicrobial therapy in the nursing home setting. The primary aim of this study is to test the efficacy of two oral cranberry capsules per day in the reduction of bacteriuria plus pyuria in female nursing home residents. These aims will be accomplished by conducting a double blind randomized placebo controlled efficacy trial of two oral cranberry capsules daily versus placebo in a cohort of Connecticut female nursing home residents.

This study will investigate whether there is a particular dose of cranberry capsules that is effective in preventing the occurrence of urinary tract infections in females at least 65 years of age or older who live in a nursing home and who have a history of urinary tract infections. The Yale research team will be enrolling 80 subjects in total over several nursing home locations within Connecticut.

Investigators will evaluate clinical decision support nudges informed by behavioral science and directed at primary care clinicians. These will be used to reduce commonly misused, and potentially harmful, diagnostic and therapeutic actions that occur in the care of older adults (e.g. overtreatment of type 2 diabetes, misuse of PSA screening, misuse of urine testing in women with nonspecific symptoms or no symptoms.

The purpose of this research study is to compare the effectiveness and efficiency of using a sterile sheath (EndoSheath®) during cystoscopy versus a standard scope.

Overtreatment of asymptomatic bacteriuria (ABU) is a quality, safety, and cost issue, particularly as unnecessary antibiotics lead to emergence of resistant pathogens. The investigators' proposal to bring clinical practice in line with published guidelines has significant potential to reduce unnecessary antibiotic use for ABU in the VA healthcare system, thus improving the quality and safety of veterans' healthcare. The investigators' study will also provide important insights about how to implement and sustain evidence-based clinical practice within VA hospitals.
