Active clinical trials for "Bacteriuria"

Asymptomatic bacteriuria (AB) is a condition in which bacteria are detected in urine culture without urinary symptoms. The inappropriate use of antibiotic treatment for AB selects bacterial flora to express resistance mutations. Reducing inappropriate antibiotic use for AB is difficult, since the microbiology laboratory cannot distinguish patients with AB. The investigators study will use a restricted laboratory report requesting the physician to call the laboratory for culture results. The restricted report may reduce the rate of inappropriate treatment of AB.

Urinary tract infection (UTI) continues to be the leading cause of infection and hospitalization in post-kidney transplant (RT) surveillance. Facts such as immunosuppression, anatomical alterations and catheters are part of the factors that contribute to a high prevalence of this condition. The incidence during the first trimester is highly variable and ranges between 15 and 50 %. This variability often depends on the definition of UTI, which sometimes overlaps with asymptomatic bacteriuria (AB). Currently the indication for treatment of AB is clear in pregnant patients and urological procedures. In post-RT surveillance, the treatment of AB is controversial. The use of Trimetropim Sulfamethoxazole during the first 6 months post RT is currently a recommendation, however new evidence has found the absence of benefit in the treatment of AB. Given the high prevalence of post RT AB and the increase in bacterial resistance, determining the usefulness of searching for and treating post RT AB is a priority in this population. Methodology: Randomized Controlled trial of kidney transplant candidates which will be randomized in the following groups: Group 1 (intervention) where the urine cultures will be analyzed openly, and in the case of asymptomatic bacteriuria, treatment based on the germ and antibiogram will be prescribed. Group 2 will undergo urine cultures at the same post-transplant times, the results will not be known by the clinical team and the participants will not receive treatment in the presence of present AB. Both groups, in the presence of UTI symptoms, will undergo urine culture and receive empirical treatment, which will be adjusted based on an antibiogram. The primary objective is to assess the prevalence of UTI, pyelonephritis, UTI-related hospitalizations, and antimicrobial resistance. As a secondary objective, the germs and associated virulence genes will be analyzed. Surveillance will be carried out for two months after transplantation and the predefined times for the evaluation of the BA will be: after the removal of the urinary catheter, week 3 and after the removal of the ureteral stent (month 2).

The purpose of the study is to compare the safety and effectiveness of oral levofloxacin (an antibiotic) with that of oral ciprofloxacin in the treatment of complicated urinary tract infections in adults.

The purpose of the study is to determine if treatment of pregnant women with urine cultures with a low level of bacteria (less than 100,000 colony forming units (CFU)) may decrease adverse pregnancy outcomes.

The major hypothesis to be tested is that there was no difference in the clinical outcome between 7(short-course) and 14(traditional-course) days of antibiotic treatment for asymptomatic bacteriuria early after kidney transplantation.

Staphylococcus aureus is a frequent cause of primary or secondary bacteremia. It is also responsible for many cases of infective endocarditis, for which the therapeutic management is specific. The frequency of infective endocarditis among Staphylococcus aureus bacteremias varies between 2.7% and 23.4%. Many factors associated with the risk of developing endocarditis in patients with S. aureus bacteremia have been described. Two parameters of potential interest remain excluded from this work: blood culture growth time, a marker of bacterial inoculum, and the presence of bacteriuria, which is common during bacteremia. The objective of this study is to evaluate the interest of these two parameters in the prediction of the presence of endocarditis during S. aureus bacteremia. Investigators will conduct a retrospective study including all patients managed for Staphylococcus aureus bacteremia and in whom a urine culture was performed. The primary objective is to describe the factors associated with the occurrence of endocarditis in patients managed for S. aureus bacteremia and who received a urine cytobacteriological examination (UCE). The secondary objectives are: to evaluate the factors associated with the occurrence of S. aureus bacteriuria in patients with S. aureus bacteremia and to evaluate the risk factors for mortality in patients managed for S. aureus bacteremia.

The purpose of this study is to compare antibiotics versus no-treatment in kidney transplant recipients with asymptomatic bacteriuria.

This a prospective, non-controlled, open, multi-center study evaluating the reduction of bacteriuria after bladder irrigation with chlorhexidine in spinal cord injured patients with chronic bacteriuria practicing intermittent catheterisation (IC). Patients will be treated with chlorhexidine for bladder irrigation twice daily for a maximum of 7 days. The study hypothesis is that bladder irrigation with chlorhexidine is efficient for a short term reduction of bacteriuria in patients performing intermittent catheterization (IC).

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.
