D-mannose: a promising support for acute urinary tract infections in women. A pilot study
The results of this study suggest that D-mannose can be an effective aid in acute cystitis management and also a successful prophylactic agent in a selected population; however, more studies will certainly be needed to confirm the results of our pilot study.
Role of D-Mannose in the Prevention of Recurrent Urinary Tract Infections: Evidence from a Systematic Review of the Literature
D-Mannose was effective in reducing the incidence of recurrent UTIs and prolonging UTI-free periods, which consequently increased quality of life. PATIENT SUMMARY: D-Mannose is a sugar that seems to reduce the incidence of recurrent urinary tract infections and associated bothersome symptoms. It also leads to a longer duration between episodes of recurrences and consequently improves patient quality of life. D-Mannose can be used as a supplementary or alternate treatment for recurrent urinary tract infections.
D-mannose vs other agents for recurrent urinary tract infection prevention in adult women: a systematic review and meta-analysis
We performed a systematic review and meta-analysis to determine whether D-mannose reduces urinary tract infection recurrence (ie, cumulative incidence) in adult women with recurrent urinary tract infection compared with other prevention agents. Secondary outcomes included side effects and compliance with D-mannose use. D-mannose appears protective for recurrent urinary tract infection (vs placebo) with possibly similar effectiveness as antibiotics.
Alternative to antibiotics for managing asymptomatic and non-symptomatic bacteriuria in older persons: a review
Recurrent urinary tract infection (UTI) is one of the most common reasons for long-term antibiotic use in frail older people, and these individuals often have non-symptomatic bacteriuria. This article reviews the literature and recommendations for the treatment of UTIs particularly in the older population (>65 years). It considers the question: is there an alternative for antibiotics for asymptomatic and non-symptomatic bacteriuria in older adults? D-mannose powder has been recommended for the treatment of UTIs, as when applied locally, it reduces the adherence of Escherichia coli. In one study, D-mannose was reviewed for the prophylaxis of recurrent UTIs in women, and the findings indicated that it may be useful for UTI prevention instead of prophylactic antibiotics.
New support for a folk remedy: cranberry juice reduces bacteriuria and pyuria in elderly women
Cranberry juice has developed a following as a simple, nonpharmacologic means to reduce or treat urinary tract infections, yet the scientific basis for such a claim has been lacking. A new study suggests that bacterial infections (bacteriuria) and associated influx of white blood cells into the urine (pyuria) can be reduced by nearly 50% in elderly women who drink 300 mL of cranberry juice cocktail each day over the course of a 6-month study. The results of this study suggest that consumption of cranberry juice is more effective in treating than preventing bacteriuria and pyuria. Along with earlier reports on the ability of cranberry juice to inhibit bacterial adherence to urinary epithelial cells in cell culture, this new work suggests that drinking cranberry juice each day may be clinically useful. Additional work must be conducted, however, to more completely define the efficacy of cranberry juice.
A Review of Cranberry Use for Preventing Urinary Tract Infections in Older Adults
Urinary tract infections (UTIs) are one the of the most common types of infections in adults older than 65 years of age. Preventing UTIs with prophylactic antibiotics increases the risk of side effects and microbial resistance, and is costly. Cranberry fruit and juices contain the compound proanthrocyanidins (PACs), specifically proanthrocyanidin-A, which exerts antiadhesion characteristics against bacteria. Cranberry products therefore have been an attractive, nonantibiotic preventative option for UTIs
Cranberry Reduces the Risk of Urinary Tract Infection Recurrence in Otherwise Healthy Women: A Systematic Review and Meta-Analysis
Cranberry (Vaccinium spp.) has been advocated for treatment of urinary tract infection (UTI); however, its efficacy is controversial. Women have a 50% risk of UTI over their lifetime, and ∼20-30% experience a subsequent UTI recurrence. These results suggest that cranberry may be effective in preventing UTI recurrence in generally healthy women
Cranberries for preventing urinary tract infections
Cranberries (particularly in the form of cranberry juice) have been used widely for several decades for the prevention and treatment of urinary tract infections (UTIs). The aim of this review is to assess the effectiveness of cranberries in preventing such infections. There is some evidence from two good quality RCTs that cranberry juice may decrease the number of symptomatic UTIs over a 12 month period in women.
Effectiveness of D-mannose, Hibiscus sabdariffa and Lactobacillus plantarum therapy in prevention of infectious events following urodynamic study
The urodynamic study is an invasive examination that allows a thorough evaluation of the functional activity of the lower urinary tract (bladder, urethra). The execution of urodynamic study exposes the patient to the risk of contracting infections of the lower urinary tract. Prevention of urinary tract infections consists in the avoidance of risk factors and prophylaxis with antimicrobial and non-antimicrobial measures. In this article, we aimed to evaluate the effectiveness of a phytotherapeutic product composed of D-mannose, Hibiscus sabdariffa, and Lactobacillus plantarum in the prevention of infectious events following invasive urodynamic examination.
Exploring the effect and mechanism of Hibiscus sabdariffa on urinary tract infection and experimental renal inflammation
Here we surveyed the effect of roselle drink on the prevention of UTI in long-term care facilities and analyzed the anti-inflammatory potential of roselle on lipopolysaccharide (LPS)-induced renal inflammation in mice. This is the first report applying clinical observation-guided transcriptomic study to explore the application and mechanism of roselle on UTI. Our findings suggested that roselle drink ameliorated LPS-induced renal inflammation via downregulation of cytokine network, pro-inflammatory product production, and NF-κB pathway. Moreover, this report suggested the potential benefit of roselle drink on UTI.
Hibiscus sabdariffa L. in the treatment of hypertension and hyperlipidemia: a comprehensive review of animal and human studies
The effectiveness of Hibiscus sabdariffa L. (HS) in the treatment of risk factors associated with cardiovascular disease is assessed in this review by taking a comprehensive approach to interpreting the randomized clinical trial (RCT) results in the context of the available ethnomedical, phytochemical, pharmacological, and safety and toxicity information. HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hyperlipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C. Anthocyanins found in abundance in HS calyxes are generally considered the phytochemicals responsible for the antihypertensive and hypocholesterolemic effects, however evidence has also been provided for the role of polyphenols and hibiscus acid. A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor. This comprehensive body of evidence suggests that extracts of HS are promising as a treatment of hypertension and hyperlipidemia
Herbal medicines as diuretics: a review of the scientific evidence
There is increasing interest in the health and wellness benefits of herbs and botanicals. This is with good reason as they might offer a natural safeguard against the development of certain conditions and be a putative treatment for some diseases. One such area may be the lowering of blood pressure in those where it is elevated (i.e., hypertension). One class of clinical medicines used to lower blood pressure are known as diuretics and work by increasing the excretion of urine from the body as well as the amount of sodium in urine. There are a growing number of studies purporting diuretic effects with traditional medicines. The aim of this article was to review these studies and identify which extracts promote diuresis (which we assessed on terms of urine excreted and urinary sodium excretion) and also to identify the research needs in this area. We identified a number of species and genuses reporting diuretic effects. Of these, the most promising, at the present time, are the species Foeniculum vulgare, Fraxinus excelsior, Hibiscus sabdariffa ...
Dandelion Root Extract
The diuretic effect in human subjects of an extract of Taraxacum officinale folium over a single day
In this pilot study, a high-quality fresh leaf hydroethanolic extract of the medicinal plant T. officinale (dandelion) was ingested by volunteers to investigate whether an increased urinary frequency and volume would result. Based on these first human data, T. officinale ethanolic extract shows promise as a diuretic in humans.
Isolation and Identification of Compounds from Bioactive Extracts of Taraxacum officinale Weber ex F. H. Wigg. (Dandelion) as a Potential Source of Antibacterial Agents
Currently, the most effective treatment for recurrent urinary tract infections in women is antibiotics. However, the limitation for this treatment is the duration and dosage of antibiotics and the resistance that bacteria develop after a long period of administration. With the aim of identifying mainly novel natural agents with antibacterial activity, the present study was undertaken to investigate the biological and phytochemical properties of extracts from the leaves Taraxacum officinale. The structural identification of compounds present in hexane (Hex) and ethyl acetate (AcOEt) extracts was performed by mass spectrometry (GC-MS) spectroscopic techniques and nuclear magnetic resonance (NMR) with the major compounds corresponding to different sesquiterpene lactones (α-santonin, glabellin, arborescin, and estafiatin), monoterpene (9,10-dimethyltricycle [188.8.131.52 (2,5)]decane-9,10-diol), phytosterol (Stigmasta-5,22-dien-3β-ol acetate), terpenes (lupeol acetate, pregn-5-en-20-one-3β-acetyloxy-17-hydroxy, 2-hydroxy-4-methoxy benzaldehyde), and coumarin (benzofuranone 5,6,7,7-a-tetraaldehyde-4,4,7a-trimethyl). The results obtained show that the Hex extract was highly active against Staphylococcus aureus showing a MIC of 200 μg/mL and moderately active against Escherichia coli and Klebsiella pneumoniae with MIC values of 400 μg/mL and 800 μg/mL for the other Gram-negative strains tested with Proteus mirabilis as uropathogens in vitro. Therefore, the effective dandelion extracts could be used in the development of future products with industrial application.
Lactuca indica extract interferes with uroepithelial infection by Escherichia coli
Uropathogenic Escherichia coli is the major cause for urinary tract infections (UTI). Due to emerging antimicrobial resistances treatment of UTI is becoming increasingly difficult. Therefore, alternative treatment strategies are required. We sought to investigate the molecular mechanisms of a traditionally used decoction from Vietnamese dandelion (Lactuca indica L.) mediating local protection of the bladder epithelium. These findings indicate that, in addition to its diuretic action, Lactuca indica exhibits secondary effects directly on epithelial cells which may protect against Escherichia coli infection. These properties might be useful for the development of alternative strategies in the treatment of UTI.
