Filter by:Approximately, 3% of males and 8% of females will develop a urinary tract infection (UTI) during childhood, and most of these will be effectively treated by short-term antibiotic therapy. A subset of these children (20-48%), will develop recurrent UTI (RUTI), which may have long-term effects in the form of hypertension or renal damage. In an effort to prevent RUTIs physicians prescribe sulfamethoxazole-trimethoprim (Septra) or nitrofurantoin as low dose antibiotic prophylaxis. However, recent evidence suggests that during prophylactic therapy the body is exposed to antibiotic levels capable of increasing antibiotic resistance and bacterial virulence. This has been shown to be true in the uropathogens E. coli and Staphylococcus saprophyticus, yet it is not known if Enterococcus sp. demonstrate similar mechanisms. Additionally, antibiotics have been shown to disrupt the natural balance of the human microbiome, potentially leading to major long term problems. As a uropathogen, enterococci consistently rank in the top 3 causes of RUTI, especially in children under 3 years of age. Additionally, Enterococcus is notorious for developing antibiotic resistance and studies have shown that children with enterococcal UTIs exhibit a higher rate of recurrence than those with non-enterococcal UTIs. The investigators hypothesize the current practice of antibiotic prophylaxis in children with RUTI is detrimental and can change the bacterial and sensitivity profiles of these patients.
Purposes of this study will be as follows: 1. To design a prospective, randomized, and open-labeled study to investigate the effect and the side effect of MPD in combination with conventional antibiotics to affect clinical course, outcome, and medical expenses. 2. To compare level of the urinary and serum cytokines before and after received MPD for the following sub-aim: I. To determine the population who is benefit from MPD to reduce the severity of clinical course and subsequent renal scarring. II. To understand the mechanism by which the MPD could shorten the clinical course and reduce the renal scarring.
The purpose of this study is to determine whether point-of-care susceptibility testing improve correct choice of antibiotics, clinical and microbiological outcome in patients with uncomplicated urinary tract infection in general practice compared to point-of-care urine culture.
The purpose of this study was to determine the efficacy and safety of intravenous cefiderocol (S-649266) in hospitalized adults with complicated urinary tract infections caused by Gram-negative pathogens.
This study is aiming to evaluate the sensitivity of uropathogens isolated in patients with community acquired UTI with Enoxacin in comparison to other antimicrobials. While Secondary objective is to study the spectrum of uropathogens responsible for community acquired UTI in local population
The purpose of this study is to compare the effectiveness of antibiotic flomoxef with cefepime for the treatment of complicated urinary tract infections (cUTIs) in Russian adults.
The objective is to determine if data from the National Insurance Health card (giving antibiotics and hospitalizations in the past 18 months) allow to predict the individual risk of antibiotic resistance and to identify population groups for which probabilistic antibiotics regimen of urinary tract infection could be simplified
This Phase I multi-center placebo controlled study is conducted in healthy women with a history of recurrent urinary tract infections (UTI) aged between 18 and 70 years.
According to the World Health Organization, hundreds of millions of patients are affected by health-care associated infections worldwide each year, resulting in prolonged hospital stays, long-term disabilities, deaths, and financial losses for health systems. The most common hospital-acquired infection is Urinary Tract Infection (UTI), accounting for almost 40% of all nosocomial infections. Most hospital-acquired UTIs are associated with catheterization. In fact, urinary catheter-related bacteriuria is the most common health care associated infection worldwide. Catheter-associated UTI (CAUTI) develops following adhesion of planktonic bacteria to the surface of the catheter and colonization, creating a persistent environment called a biofilm. The nature of biofilm structure together with the physiological attributes of biofilm organisms confers an inherent resistance to various antimicrobial agents such as antibiotics, disinfectants or germicides, augmenting the potential of these pathogens to cause infections in catheterized patients. Nitric oxide (NO) is a naturally-produced gas molecule with broad-spectrum antimicrobial activity. NO is used in the clinics to treat pulmonary hypertension in neonates and adults. Studies have shown that low-dose NO is associated with prevention of biofilm formation, biofilm dispersal and elimination of bacteria. It is suggested that NO prevents bacteria attachment to catheter surfaces and inhibits biofilm formation in a mechanism involving reduction and modification of proteins that mediate cell-substrate and cell-cell interactions. The investigators team, using a proprietary technology impregnate urinary catheters with NO (i.e. NO-impregnated catheters). These catheters release low concentration of NO following exposure to urine over a 14-day period. In vitro studies showed that NO-impregnated catheters prevent bacterial colonization and biofilm formation of Escherichia coli on exterior and luminal surfaces of the catheters. In addition, NO released from these catheters is able to eradicate up to 4log colony forming unit/ml of bacteria within the surrounding media. Moreover, NO-impregnated catheters exhibit superior performance compared to silver-coated catheters, and similar anti-infective properties compared to antibiotic-coated catheters. Primary objectives: To assess the safety and tolerability of NO-impregnated catheters in patients older than 18 years old undergoing radical prostatectomy and catheterized for 7-14 days.
Nissle 1917 is an E. coli based probiotic used in the Europe for close to 100 years to treat gastrointestinal disorders and infections. The investigators will assess the safety and tolerability of this medication in Americans in a Phase 1 trial.
