Cranberry is reported to have health benefits including prevention of urinary tract infections and other chronic diseases, due to the high content of polyphenols including flavonols and flavan-3-ols. The aim of this study was to determine the clearance of flavonol glycosides and flavan-3-ols and/or their metabolites in human urine. Ten healthy women volunteers ingested 240 ml cranberry juice containing flavonol glycosides. Urine samples were collected at 0, 90, 225 and 360 minutes post-ingestion. While flavan-3-ols were not detected, five flavonol glycosides common in cranberry were identified...

Drinking of cranberry fruit juice and application of commercial preparations containing the cranberry extracts are recommended in the prevention and treatment of urinary tract infections (UTIs), especially in women with recurrent UTIs. Many studies focus on the activity of cranberries against uropathogenic Escherichia coli (E. coli) strains. However, the knowledge of the cranberry effect on Gram-positive Enterococcus faecalis (E. faecalis) is limited. Therefore, the aim of our study was to establish the activity of commercial concentrated cranberry extract on the growth, virulence factors and biofilm formation of E...

Cytochrome P450 inhibition through fruit supplement interactions often results in increased serum levels of calcineurin inhibitors, including tacrolimus. Cranberry extract is a supplement often used for the prevention of recurrent urinary tract infections (UTIs), which are common in renal allograft recipients. To our knowledge, a decrease in serum levels of tacrolimus as a result of cranberry extract interaction is unreported. A 40-year-old renal transplant patient taking cranberry extract capsules for her recurrent cystitis presented asymptomatically with low serum levels of tacrolimus...

BACKGROUND: Urinary tract infections (UTIs) are among the most common bacterial infections and are often treated with antibiotics. Concerns about multidrug-resistant uropathogens have pointed to the need for safe and effective UTI-prevention strategies such as cranberry consumption. OBJECTIVE: We assessed the effects of the consumption of a cranberry beverage on episodes of clinical UTIs. DESIGN: In this randomized, double-blind, placebo-controlled, multicenter clinical trial, women with a history of a recent UTI were assigned to consume one 240-mL serving of cranberry beverage/d (n = 185) or a placebo (n = 188) beverage for 24 wk...

Proteus mirabilis is a major cause of catheter-associated urinary tract infection (CAUTI), emphasizing that novel strategies for targeting this bacterium are needed. Potential targets are P. mirabilis surface-associated swarming motility and the propensity of these bacteria to form biofilms that may lead to catheter blockage. We previously showed that the addition of cranberry powder (CP) to lysogeny broth (LB) medium resulted in impaired P. mirabilis swarming motility over short time periods (up to 16 h). Herein, we significantly expanded on those findings by exploring (i) the effects of cranberry derivatives on biofilm formation of P...

PURPOSE: Urinary tract infections (UTIs) are widespread and affect a large portion of the human population. Cranberry juices and extracts have been used for UTI prevention due to their content of bioactive proanthocyanidins (PACs), particularly of the A type (PAC-A). Controversial clinical results obtained with cranberry are often due to a lack of precise determination and authentication of the PAC-A content. This study used Oximacro (Biosfered S.r.l., Turin, Italy), a cranberry extract with a high content of PAC-A, to prevent UTIs in female and male volunteers...

Cranberry juice has been recognized as a treatment for urinary tract infections on the basis of scientific reports of proanthocyanidin anti-adhesion activity against Escherichia coli as well as from folklore. Xyloglucan oligosaccharides were detected in cranberry juice and the residue remaining following commercial juice extraction that included pectinase maceration of the pulp. A novel xyloglucan was detected through tandem mass spectrometry analysis of an ion at m/z 1055 that was determined to be a branched, three hexose, four pentose oligosaccharide consistent with an arabino-xyloglucan structure...

Urinary tract infections (UTI) are one of the most frequent extraintestinal infections caused by Escherichia coli (ExPEC). Cranberry juice has been used for decades to alleviate symptoms and prevent recurrent UTI. The putative compounds in cranberries are proanthocyanidins (PAC), specifically PAC with "A-type" bonds. Since PAC are not absorbed, their health benefits in UTI may occur through interactions at the mucosal surface in the gastrointestinal tract. Recent research showed that higher agglutination of ExPEC and reduced bacterial invasion are correlated with higher number of "A-type" bonds and higher degree of polymerization of PAC...

Urinary tract infection (UTI) is a major problem in nursing homes, and the mainstay of treatment is antibiotics. The increasing prevalence of uropathogens resistant to antimicrobial agents has stimulated interest in specific nutrients, for example, cranberries, to prevent recurring UTI. Black chokeberry (Aronia melanocarpa [Michx] Elliott) is a rich source of phenolics, and thus, dietary intake of black chokeberry juice may reduce the incidences of UTI requiring medical treatment. In this pilot study, we examined the frequency of medically treated UTI among residents in 6 nursing homes who were offered black chokeberry juice or a placebo during a 6-month crossover intervention...

Cranberry juice polyphenols have gained importance over the past decade due to their promising health benefits. The bioactive component, proanthocyanidins is mainly responsible for its protective effect. A lot has been said about its role in urinary tract infection and other systemic diseases, but little is known about its oral benefits. An extensive search was carried out in the PubMed database using the terms "cranberry polyphenols" and "periodontitis" together. The institute library was also thoroughly scrutinized for all relevant information...

Urinary tract infections (UTIs) are common among children and adults, with the greatest prevalence in women. One-half of all women will develop a UTI at some point. Approximately one-third of children with UTIs develop recurrent infections, and because recurrent UTIs have been thought to lead to renal scarring, practice has focused on identifying patients at risk of UTIs and limiting recurrence. It is difficult to determine which children are at risk of renal damage, and the benefits of antibiotics or surgery in preventing recurrent UTIs in children are unclear...
