269 Clinical Trials for Various Conditions
A randomized, double-blind, placebo-controlled, 12-month study to determine the effectiveness of D-mannose (2g daily) supplementation in rUTI (recurrent urinary tract infection) prevention in post-menopausal women.
The goal of this clinical trial is to learn if the drug Nitrofurantoin (NF) taken as a daily antibiotic, works to treat cystitis compared to electrofulguration (EF) and Nitrofurantoin (NF) daily antibiotic.
A two-arm randomized control trial evaluating rates of urinary tract infection in post-menopausal women on vaginal estrogen with recurrent urinary tract infections.
* The goal of this clinical trial is to learn about medication adherence to difference types of vaginal estrogen in women with low levels of estrogen (for example, post-menopausal women) who have recurrent urinary tract infections. Medication adherence means whether patients take their medicine as prescribed. * Another goal of the study is to learn about changes to the skin of the vagina before and after estrogen treatment, using a specialized imaging modality called optical coherence tomography, which is similar to receiving an ultrasound. * A third goal of the study is to learn about changes to the microbiome (all the bacteria that naturally live in our bodies) before and after treatment with vaginal estrogen. The researchers will be looking specifically at the microbiome in the urine and the vagina. Participants will be assigned by chance (like the flip of a coin) to receive one of three possible vaginal estrogen treatments - cream, tablets, or drug-eluting ring. * The main study tests and procedures include an initial visit in which the researchers will collect baseline information about participants and have participants complete a series of questionnaires. * There will then be 3 and 6 month follow-ups in which the researchers will have participants complete additional questionnaires and the researchers also assess whether participants are using the vaginal estrogen treatment that you were prescribed. If a participant is part of the microbiome cohort, they will also be asked to do the following: * a baseline visit in which urinary and vaginal specimens are collected to assess their baseline microbiome. The vaginal specimen collection will involve a q-tip swab inside the vagina; it is similar to a pap smear. * Finally, participants will have an imaging modality performed on their vagina called optical coherence tomography, which allows the researchers to assess the thickness of the vaginal walls and the blood vessel density. This imaging modality involves the insertion of a thin probe into the vagina to obtain the images of the vaginal wall. * These tests will then be repeated at 6 months to assess if vaginal estrogen treatment causes changes to the vagina.
Patients with recurrent UTI were randomized to receive either the probiotic Sacchromyces Boulardii at enrollment, and the intracellularly active Ciprofloxacin with their first UTI episode after enrollment, or they received standard of care treatment.
Vaginally applied estrogen has been shown to decrease the incidence of Recurrent Urinary Tract Infection (rUTI) in post-menopausal women. However, prior studies have shown the compliance rate for topical estrogen cream is low. The vaginal estradiol tablet has been shown to be preferred by patients being treated for genitourinary syndrome of menopause and has improved compliance. There are no studies looking at the preference of post-menopausal women with rUTI for vaginal estradiol tablet as an alternative to vaginal estradiol cream.
Menopausal women have an increased risk of recurrent urinary tract infections. This is likely due in part to hormonal changes occurring during menopause. As estrogen falls, the vaginal microbiome shifts from a healthy one to a less healthy one. Because the vagina is close to the urethra, this vaginal microbiome shift contributes to a loss of protection against urinary tract infections (UTIs). The investigators are asking whether improving the vaginal microbiome using an over-the-counter vaginal hygiene system can reduce frequency of recurrent UTI in menopausal women.
Among postmenopausal women who suffer from recurrent urinary tract infections (UTI), vaginal estrogen therapy prevents UTI recurrences for 50% of sufferers. This research will investigate why some women benefit but others do not, focusing on (a) the effects of vaginal estrogen therapy on the bacteria that inhabit the vagina and bladder, (b) its influence on immune responses in both compartments, and (c) the extent to which those changes are critical to successful UTI prevention. The findings will be a first step in the development of more effective strategies to prevent UTI, one of the most common and costly benign urologic conditions.
Due to rising antibiotic resistance, there has been a focus on non-antibiotic prophylactic measures for postmenopausal patients with recurrent urinary tract infections (rUTI), one of which is the safe and efficacious option of vaginal estrogen therapy. Standard application of vaginal estrogen cream entails intravaginal application of the cream twice a week, but some providers counsel patients with rUTI to apply a small, pea-sized amount to the periurethral area. This ideally reduces the amount of vaginal estrogen used while attaining a similar effect. However, to date, there is no data to prove that the periurethral technique of application is similar or non-inferior to intravaginal application in preventing UTI.
An over-the-counter vaginal care system is being tested to see if it may be effective in preventing recurrence of symptomatic urinary tract infection (UTI) in women who have had multiple UTIs within the past year.
The primary objective is to determine if polymerase chain reaction (PCR) (UTIP™) is more sensitive in identifying urinary tract infections (UTI's) than standard urine cultures.
Women over the age of 60 years have an estimated 10 to 15 % risk of recurrent urinary tract infections (UTI). This is believed to be due to hormonally induced changes in the vaginal flora associated with menopause. After menopause, there is a chemical changes in the vagina that may predispose to bacterial infections. The role of vaginal estrogen creams to restore vaginal atrophy and prevent urinary tract infections has been well characterized. Vaginal testosterone (VT) application use in postmenopausal breast cancer patients on aromatase inhibitors have been shown to improve vaginal pH, vaginal atrophy symptom scores, dyspareunia, and vaginal dryness. Although testosterone has been used to improve sexual function in postmenopausal women, the effects of VT on vaginal flora and recurrent UTIs are unknown. The purpose of this study is to determine whether topically applied vaginal testosterone cream is more effective than placebo in reducing the incidence of urinary tract infections in postmenopausal women with recurrent urinary tract infections and to ascertain the effects of topical estrogen on the vaginal pH and flora.
This study will assess patients who have recurrent urinary tract infections and kidney stones which are not blocking the kidney or causing other problems. Currently, we don't know if taking out these stones will improve recurrent urinary tract infections or not. Patients will make a decision with their surgeon about removing or monitoring their stone(s). Whether or not their infections continue with surgery or monitoring will be noted, and this information may help to inform future treatment decisions. The purpose of this study is to assess if treatment of these asymptomatic stones affects the rate of recurrent urinary tract infections.
Randomized controlled trial to determine clinical and microbiome difference between fractional CO2 Laser and vaginal estrogen in treating patients with recurrent urinary tract infection (UTI).
Urinary tract infections (UTIs) are bothersome and more likely to occur in postmenopausal women. Frequent UTIs, as well as other problems with the urinary and genital systems such as painful sex and urinary frequency/urgency, are part of a symptom complex called genitourinary syndrome of menopause (GSM). Prasterone (Intrarosa®) is a man-made steroid that helps with painful sex in postmenopausal women. Because previous studies have shown prasterone to help with other GSM problems, this study was designed to investigate if prasterone used in the vagina decreases the number of UTIs in postmenopausal women.
This pilot study is a single-site randomized, double blinded placebo-controlled in females with recurrent multi-drug resistant (MDR) urinary tract infections(UTI). Our study hypothesizes that a novel probiotic strain improves antibiotic sensitivity patterns in these former MDR UTIs.
Several methods are available for use in the prevention of recurrent urinary tract infections (UTIs) over the past few decades. These methods include suppressive antibiotics, estrogen cream, methenamine hippurate, d-mannose, cranberry, probiotics, and vitamin C. Of these, the majority of the literature is in favor of use of suppressive antibiotics for preventing UTIs. However, this data is now about 10 years old. Increasing use of antibiotics over the years has lead to increased resistance of bacteria. In addition, long-term antibiotic use has several adverse effects, some life-threatening. There is recent literature evaluating the use of several of the alternatives to suppressive antibiotics with mixed results. A comparative study of the efficacy of methenamine hippurate to suppressive antibiotics is lacking in the current literature. Several early partly-randomized trials done with methenamine hippurate have shown promising results, but are only as recent as 1987. The primary objective of this prospective, randomized study is to determine whether there is a significant difference in the prevention of recurrent UTIs when given either methenamine hippurate or daily suppressive antibiotics. The secondary objective of this study is to determine how well patients are able to tolerate each of these medications and what adverse effects are observed in a given 1 year time period. The long-term goals of this study are to find an alternative to using suppressive antibiotics, potentially with a lower adverse effect profile and less of the dangers of long term antibiotic use. Finding an alternative to suppressive antibiotics would also tackle the issue of antibiotic resistance.
Recurrent urinary tract infections are quickly becoming a public health obstacle in our aging population. Almost 50% of women have at least one urinary tract infection in their lifetime; following this first infection, there is a 25-35% chance that she will have another infection in the subsequent 3-6 months. With each documented infection, a patient receives anywhere from a three to seven day course of antibiotics for treatment. Repeated courses of antibiotics often lead to the development of multi-drug resistant infections that are difficult to treat with our arsenal of oral medications. It is theorized that most, if not all, urinary tract infections are caused by bacteria from the gastrointestinal tract. If there is a generalized gut dysbiosis due to repeated courses of oral antibiotics, it will likely be difficult to ever adequately treat repeat urinary tract infections. This same theory led to the development and utilization of fecal microbiota transplantation in the treatment of refractory Clostridium difficile diarrhea. There are now several studies that have reported on the efficacy of fecal transplantation in the treatment of C.difficile infections as well as the correction of gut dysbiosis. Given this positive response in treatment of refractory infectious diarrhea, the investigators propose that the correction of gut dysbiosis can also treat refractory recurrent urinary tract infections. Therefore, the investigators propose this pilot study to determine the effectiveness of fecal transplantation in the treatment of refractory, recurrent urinary tract infections.
Urinary Tract Infections (UTIs) are the second most common infection in the body. UTIs account for five percent of all visits to primary care physicians. Many women who have had a UTI will develop recurring urinary tract infections. Recent studies suggest that some women who suffer from recurrent UTIs have urinary tracts that allow bacteria to adhere to it more readily than others. Women who suffered from bladder inflammation and recurrent UTIs were noted to have reduced UTIs and bladder inflammation with heparin bladder instillations. Heparin is a highly-sulfated glycosaminoglycan and stored within the secretory granules of mast cells and released only into the vasculature at sites of tissue injury. It has been proposed that, in addition to anticoagulation, the main purpose of heparin is defense at such sites against invading bacteria and other foreign materials. The central question the research is intended to answer is does Heparin bladder instillations decrease UTI rates in patients.
The investigators would like to know if the use of vaginally applied estrogen can prevent the problem of repeated urinary tract infections (UTI) in women who have gone through menopause. The investigators will use two forms of vaginal estrogen that are available by prescription (a ring and a cream) and compare their efficacy to that of a placebo (without any active ingredient). The investigators are going to look at if the vaginal estrogen can prevent UTIs altogether and also the number of UTIs each group experiences over a 6 month period. After 6 months, all subjects will receive vaginal estrogen and the women on the non-active treatment will be able to choose whether they would like to use either the estrogen ring or cream. The investigators will then be able to compare the number of UTIs on and off active vaginal estrogen treatment within those subjects who started on the placebo. The investigators are also going to look at quality of life before and during treatment using questionnaires and whether subjects stop using the treatments or do not use them as directed (compliance).
The purpose of this study is to compare the effects of a cranberry juice beverage on rates of Urinary tract infection (UTI) recurrence in women with a history of UTI.
Probiotics are dietary supplements containing potentially beneficial bacterial strains such as Lactobacillus. The safety of oral administration of probiotics has been demonstrated in hundreds of studies using adults over the last 30 years. Very few studies have been conducted with children. UTI in girls occur when virulent bacteria migrate from the rectum and colonize the vagina and peri-urethral mucosa, thus gaining access to the bladder. This study will randomize girls to ARM A (probiotics + placebo) and ARM B (antibiotics + placebo) to determine if UTIs are decreased when the probiotics are given.
Recurrent urinary tract infections (RUTIS) continue to be a major health problem in women and are now complicated by increasing antibiotic resistance. New preventive approaches are needed. Because most women with RUTI lack the normal protective Lactobacillus (LB) in their vaginal flora, we hypothesized that restoration of LB would reduce RUTIS. In this trail, women with recent UTI are randomized to receive either LB or placebo vaginal capsules and are followed for side effects, for colonization with LB and for occurrence of RUTI over hte next four months.
The purpose of this study is determine whether a vaginal mucosal vaccine given to women with a history of recurrent urinary tract infections can reduce the number of infections occurring in a six-month study period, as compared to placebo treatment.
This study will determine whether cranberry juice is effective in reducing recurrent urinary tract infections (UTIs) in women who have had a UTI within the past year.
Managing complicated urinary tract infections (cUTIs) poses significant challenges, often resulting in the over-prescription of empiric antibiotics. This approach exposes patients to multiple antimicrobials and raises the risk of inadequate treatment efficacy. The purpose of this study is to assess and compare the clinical utility of molecular testing (PCR) versus conventional culture and sensitivity (C\&S) in managing cUTI, to identify optimal management strategies for cUTI patients. This was a multi-center (6 sites in the united states), randomized, parallel, investigator-blinded, clinical trial to assess the clinical utility of PCR by comparing the diagnostic and therapeutic outcomes of PCR diagnostic methods to those of conventional C\&S in managing cUTIs in adults. All patients who met all the inclusion criteria and non of the exclusion criteria and signed an informed consent form were enrolled and randomized to one of two testing protocols used to guide treatment (PCR guided Arm, and C\&S guided Arm). Patients were randomized in a 1:1 ratio based on their unique sequential randomization numbers assigned at enrollment. Urine samples were collected from all patients and tested using both PCR and C\&S methods before randomization; however, investigators remained blinded to the comparator test results throughout the trial. To ensure unbiased treatment decisions, clinicians were blinded to the comparator test results. Treatment was prescribed solely based on the assigned test-PCR results for the PCR arm and C\&S results for the C\&S arm. The comparator test results remained blinded until the end of the study (EOS) Urine specimens were collected using a clean-catch midstream technique at two distinct time points-at baseline visit/before randomization (Day1) and at EOS visit (Day 28)-following targeted therapy based on the assigned diagnostic arm. Collected samples were immediately stored at 2-8 ◦C until analysis to preserve sample integrity. Upon receipt, urine samples were aliquoted for parallel testing, with one portion analyzed using PCR (QuantStudio 7 or 12 and KingFisher) and the other processed using C\&S methodologies. Molecular testing (Doc Lab UTM 2.0) involved qualitative PCR amplification targeting 28 uropathogen species and 16 classes of antibiotic resistance genes, covering both bacterial and fungal pathogens. All urine samples for urine C\&S were shipped to the central laboratory. The urine culture, isolation of uropathogen(s), initial identification of pathogen(s), and bacterial counts in urine were conducted in the central laboratory. The urine samples were cultured and quantified using a calibrated loop to identify a quantitative count of bacteria at a lower limit of 10\^5 CFU/mL. All purified pathogen(s) were further analyzed for species identification and antimicrobial sensitivity The primary endpoint was the number (and percentage) of subjects in each study arm with favorable clinical outcomes (FCl) at the EOS visit. The FCl was defined as a patient's clinical response, assessed by the treating investigator, indicating either clinical improvement or cure. Clinical improvement was defined as the resolution of at least one symptom of cUTI present at baseline, absence of new cUTI symptoms, and/or avoidance of parenteral antibiotic therapy following randomization. Clinical cure was defined as the complete resolution of all acute signs and symptoms of cUTI present at baseline, to the extent that no further antimicrobial therapy (either IV or oral) was required for the treatment of the cUTI. The secondary endpoint included several assessments: * Number (and percentage) of subjects with microbiological eradication at the EOS, defined as achieving a quantitative urine culture at the EOS indicating a reduction of all uro-pathogens present at baseline to \<10\^5 colony forming unit per milliliter (CFU/mL) and the absence of baseline pathogens detected by EOS urine PCR (Cq \> 33); * Subjective measurement of treating investigator satisfaction score through a questionnaire at EOS, evaluated factors such as the ease of interpreting the test result, its availability, and its usefulness in clinical decision-making and patient management compared to the comparator; * Comparison of turnaround time between molecular diagnostic procedures and conventional diagnostic * Overall agreeability between the diagnostic results generated by PCR versus C\&S as assessed by discordant analysis * Assessment of the favorable clinical outcome of patients with discordant results \[PCR(+), CS(-) and PCR(-), CS(+)\]
Urinary tract infection (UTI) is when bacteria enter the urinary system and cause an infection. UTIs cause symptoms including burning when peeing, a feeling of an increased urge to pee, and cloudy or strong-smelling urine. Sometimes, severe UTIs can also cause fever, abdominal pain, and/or lower back pain. In the emergency department (ED), healthcare providers rely on symptoms, along with a urine analysis and a urine culture to diagnose a UTI. A urine analysis involves taking a sample of urine and analyzing different factors like color, acidity, presence of blood cells, presence of bacteria. An abnormal urine analysis increases the likelihood that patients might have a UTI, but it does not confirm it. A positive urine analysis will lead to provider's sending a sample of urine for a urine culture. A urine culture is used to grow whatever bacteria is in the collected urine. If growth is seen on the culture, then this confirms a patient has a UTI. This also specifies which bacteria grew on the culture. The lab can also take it a step further and do an antibiotic test to check which antibiotic the bacteria is sensitive to. When a urine analysis comes back abnormal in an ER setting, patients are prescribed an antibiotic before the culture and antibiotic sensitivity tests come back. If a patients condition is not critical, they will be discharged home before the culture results come back. If the culture comes back positive, the pharmacists will evaluate the culture and antibiotic sensitivity tests, then call patients to inform them whether they are taking a suitable antibiotic. This study aims to decrease the unnecessary use of antibiotics because this contributes to antibiotic resistance which is considered a global public health issue. Antibiotic resistance occurs when bacteria develop the ability to withstand certain antibiotics that used to be effective against them, which makes it difficult to treat the infection. One of the factors that increase the risk of antibiotic resistance is the overuse of antibiotics. In this study, investigators will be incorporating a prediction model and a negative callback system to decrease unnecessary antibiotic use.
Stress urinary incontinence (SUI) affects at least 40% of women in the United States. Synthetic polypropylene mid-urethral slings (MUS) are the gold standard treatment for SUI. Post-operative urinary tract infections (UTI) are one of the most common complications after MUS placement. Some studies have demonstrated that MUS placement can increase the risk of UTI up to 21-34%. Post-operative UTI can lead to significant healthcare and patient burden. This additional burden further contributes to an estimated annual cost of $1.6 billion for UTI management in the United States. With increased antibiotic usage, there is simultaneous increase in bacterial resistance leading to treatment refractory UTI. The investigators prescribe post-operative antibiotics prophylactically for 3 days after MUS placement with or without concurrent pelvic reconstructive surgery based on prior literature recommending post-operative prophylaxis. There is a greater emphasis on limiting antibiotic use given the trend of development of bacterial resistance. There are studies supporting alternatives such as methenamine for recurrent UTI prophylaxis treatment, but there are limited studies evaluating methenamine for UTI prophylaxis after MUS.
Adults 18 years or older with urinary tract infection (UTI) symptoms. Participants will be assigned to either the urine culture group or the DNA PCR study group by randomization. At time of enrollment in the study they will be also asked to fill out two questionnaires. If prescribed antibiotics for treatment of a UTI, participants will then be called the day after they are scheduled to stop their antibiotics. Participants will be asked to fill out questionnaires the day after finishing antibiotics. Participants will be enrolled in the study for a maximum of 21 days.
The purpose of this study is to assess safety, reactogenicity, and immune response of the candidate UTI vaccine compared to placebo in adults between and including 18-64 years of age (YOA), and to perform a preliminary evaluation of clinical efficacy in females between and including 18-64 YOA.
