Filter by:Cranberry and cranberry-lingonberry juice prevented urinary tract infections in children and in adults in our earlier clinical trials. The preventive effect was, however, observed late in the follow-up and the next recurrence was not prevented in children. The investigators hypothesize that cranberry-lingonberry juice should be started already during the antimicrobial treatment of acute urinary tract infection in order to maximize the preventive efficacy of the juice. In addition, the investigators aim to find the explanation for the efficacy of cranberry-lingonberry juice by analyzing the concomitant changes in the chemical composition of urine and feces as well as the changes of gut microbiota.
Patients presenting with pelvic organ prolapse will be offered the use of a pessary. Vaginal estrogen cream treatment with the pessary will be randomized amongst the patients and patient satisfaction and complication rates will be assessed during follow-up.
This project aims at investigating the duration of human fecal carriage of bacteria harboring plasmid-borne resistance genes expressing Extended Spectrum beta-lactamases (ESBL), risk factors for infections with such bacteria and persistence, mobility and spread of ESBL in the environment and within households. It also aims to compare different methods of detecting ESBL carriage and treat patients with urinary tract infection caused by these bacteria.
The purpose of this study is to see if the investigators can identify early those patients who are admitted to the hospital and have a urinary tract infection (UTI) or those patients that develop a UTI during their hospitalization.
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).
Background- In recurrent urinary tract infections (RUTIs) usual prophylactic antibiotic regimes do not change the long term risk of recurrence. Objective- D-Mannose is a sugar, it sticks to E. coli bacteria, the aim of the study was to evaluate its efficacy in the treatment and prophylaxis of recurrent UTIs. Design, setting and participants- : In this crossover trial female patient were eligible for the study if they had recurrent UTIs, that is three ore more episodes during the preceding 12 months. Suitable patients were randomly assigned to antibiotic treatment with trimethoprim/sulfamethoxazole or to a regimen of oral D Mannose for 24 weeks, and received the other intervention in the second phase of the study. Outcome measurements and statistical analysis- The time to recurrence of UTI, bladder pain (VAS p) and urinary urgency (VAS u) were evaluated at the end of antibiotic therapy and at the and of 24 weeks fo D Mannose. The results for quantitative variables were expressed as mean values and SD as they were all normally distributed (Shapiro-Wilk test). T-test for paired data was used to analyze differences of time of recurrence, VAS pain, Vas urgency and number of voidings between treatment. Data analysis was performed with STATA statistical package (release 11,1, 2010, Stata Corporation, College Station, Texas, USA).
The purpose of this clinical trial is compare the incidence of symptomatic or asymptomatic bacteriuria after transrectal ultrasound guided prostate biopsy using a single dose of fosfomycin 3 g one hour before the biopsy compared to observed with the use of a single dose of ciprofloxacin 500 mg 1 hour before biopsy.
This study will enroll 30 female patients with the first time urinary tract infection (UTI), 30 female patients with recurrent UTI and 10 female without any prior history of UTI or urinary tract pathology will be invited to serve as the controls. Urine samples will be collected in the patients at baseline, 7 days after antibiotics treatment, and 2 weeks, 4 weeks, 8 weeks, and 12 weeks. Urinalysis will be performed at each visit and urine culture will be performed at baseline and at the 2 weeks and 3 months visits. Urine samples at baseline and 3 months will be collected from the controls for comparison.
Primary Aim 1. To measure difference in pain via Faces, Legs, Activity, Cry and Consolability (FLACC) Pain Scale score at the time of transurethral bladder catheterization for urine collection in children who do and do not receive intraurethral 2% lidocaine jelly prior to catheterization. Secondary Aims 1. To assess gender differences in pain control during transurethral bladder catheterization with and without pain control using intraurethral 2% lidocaine jelly. 2. To assess patient discomfort with administration of intraurethral 2% lidocaine jelly. To assess parental impression of discomfort between intervention and control groups. 3. To assess pain associated with the administration of intraurethral 2% lidocaine jelly. 4. To measure difference in pain via Modified Behavioral Pain Scale (MBPS) score at the time of TUBC for urine collection in children who do and do not receive intraurethral 2% lidocaine jelly prior to catheterization.
