RESUMO

Background: Uropathogenic Escherichia coli (UPEC) activates innate immune response upon invading the urinary tract, whereas UPEC can also enter bladder epithelial cells (BECs) through interactions with fusiform vesicles on cell surfaces and subsequently escape from the vesicles into the cytoplasm to establish intracellular bacterial communities, finally evading the host immune system and leading to recurrent urinary tract infection (RUTI). Tailin Fang II (TLF-II) is a Chinese herbal formulation composed of botanicals that has been clinically proven to be effective in treating urinary tract infection (UTI). However, the underlying therapeutic mechanisms remain poorly understood. Methods: Network pharmacology analysis of TLF-II was conducted. Female Balb/C mice were transurethrally inoculated with UPEC CFT073 strain to establish the UTI mouse model. Levofloxacin was used as a positive control. Mice were randomly divided into four groups: negative control, UTI, TLF-II, and levofloxacin. Histopathological changes in bladder tissues were assessed by evaluating the bladder organ index and performing hematoxylin-eosin staining. The bacterial load in the bladder tissue and urine sample of mice was quantified. Activation of the TLR4-NF-κB pathway was investigated through immunohistochemistry and western blotting. The urinary levels of interleukin (IL)-1ß and IL-6 and urine leukocyte counts were monitored. We also determined the protein expressions of markers associated with fusiform vesicles, Rab27b and Galectin-3, and levels of the phosphate transporter protein SLC20A1. Subsequently, the co-localization of Rab27b and SLC20A1 with CFT073 was examined using confocal fluorescence microscopy. Results: Data of network pharmacology analysis suggested that TLF-II could against UTI through multiple targets and pathways associated with innate immunity and inflammation. Additionally, TLF-II significantly attenuated UPEC-induced bladder injury and reduced the bladder bacterial load. Meanwhile, TLF-II inhibited the expression of TLR4 and NF-κB on BECs and decreased the urine levels of IL-1ß and IL-6 and urine leukocyte counts. TLF-II reduced SLC20A1 and Galectin-3 expressions and increased Rab27b expression. The co-localization of SLC20A1 and Rab27b with CFT073 was significantly reduced in the TLF-II group. Conclusion: Collectively, innate immunity and bacterial escape from fusiform vesicles play important roles in UPEC-induced bladder infections. Our findings suggest that TLF-II combats UPEC-induced bladder infections by effectively mitigating bladder inflammation and preventing bacterial escape from fusiform vesicles into the cytoplasm. The findings suggest that TLF-II is a promising option for treating UTI and reducing its recurrence.

RESUMO

BACKGROUND: Urinary tract infections and reproductive tract infections pose significant health risks, particularly among women living in challenging conditions. Unhygienic menstrual practices can exacerbate these risks, impacting physical and psychological well-being. OBJECTIVES: This study assessed the association between unhygienic menstrual care and self-reported urinary tract infection/reproductive tract infection symptoms among refugee women. In addition, it explored the association between these symptoms and mental health, specifically depressive symptoms. DESIGN: This study adopted a cross-sectional observational design. METHODS: This study was conducted between January and March 2023, involving 387 reproductive-age refugee women. Data collected included sociodemographic information and urinary tract infection/reproductive tract infection symptoms. In addition, we used the Menstrual Practice Needs Scale to evaluate menstrual hygiene practices and the Patient Health Questionnaire-9 for depressive symptoms. Statistical analysis was performed using Python version 3.9.12. RESULTS: Of 387 refugee women, 92.25% reported having urinary or reproductive tract infection symptoms in the previous 3 months. Factors like older age (odds ratio = 1.764, 95% confidence interval = 1.083-2.873, p-value = 0.023), lower family income (odds ratio = 0.327, 95% confidence interval = 0.138-0.775, p-value = 0.011), lower educational level (odds ratio = 0.222, 95% confidence interval = 0.068-0.718, p-value = 0.012), and being married (odds ratio = 0.328, 95% confidence interval = 0.188-0.574, p-value < 0.001) were significantly associated with urinary or reproductive tract infection risk. Difficulties obtaining menstrual products and thus reusing them increased the odds of urinary or reproductive tract infection diagnosis (odds ratio = 2.452, 95% confidence interval = 1.497-4.015, p-value < 0.001). Women with urinary or reproductive tract infection symptoms exhibited higher Patient Health Questionnaire-9 scores than those without (12.14 ± 5.87 vs 9.99 ± 5.86, p-value < 0.001, respectively). CONCLUSION: This study highlights a high prevalence of urinary or reproductive tract infection symptoms among refugee women residing in camps in Jordan, which was associated with poor menstrual hygiene practices and depressive symptoms. To reduce the urinary tract infection/reproductive tract infection burden in marginalized communities, public health initiatives should enhance healthcare accessibility, provide reproductive education, and promote holistic well-being practices for refugee women.

RESUMO

The link between neonatal jaundice and urinary tract infection (UTI) remains debated, with congenital kidney and urinary tract anomalies (CAKUT) potentially playing a role. This population-based study aimed to analyze the correlations between neonatal jaundice, CAKUT, and concomitant UTI. The study cohort consisted of 2,078,122 live births from 2004 to 2014. We linked several population-based datasets in Taiwan to identify infants with unexplained neonatal jaundice and their mothers. The primary outcome was the rate of CAKUT occurring within 3 years after delivery, and the presence of concomitant UTI during neonatal jaundice hospitalization. Infants with neonatal jaundice had a significantly higher risk of CAKUT (adjusted odds ratio [aOR] 1.24, 95% confidence interval [CI] 1.11-1.39) during early childhood. Among the subtypes of CAKUT, obstructive uropathy, vesicoureteral reflux and other CAKUT were associated with an increased risk of neonatal jaundice. Infants who underwent intensive phototherapy, had a late diagnosis (> 14 days of postnatal age) or underwent a prolonged duration of phototherapy (> 3 days) exhibited a higher risk of concomitant UTI compared to other infants with jaundice. Our findings indicate a notable association between neonatal jaundice and increased risks of UTIs in the context of CAKUT. This study underscore the importance of vigilant monitoring and timely interventions for neonates presenting with jaundice, while acknowledging the complexity and variability in the progression of CAKUT and its potential connection to UTIs.

RESUMO

INTRODUCTION: We document the quality, veracity, and comprehensiveness of recurrent UTI information on YouTube to increase health care workers' (HCWs') awareness of UTI-related content online, and to identify deficits in understanding, clarify misconceptions, and reduce stigmatization risk. METHODS: High-traffic topic search terms were curated by Google Trends to extract 200 videos, of which 45 met inclusion criteria. Five independent reviewers used a standardized questionnaire based on the AUA recurrent UTI guidelines to assess the definition of UTI, marketing content, prophylaxis/prevention strategies, and antibiotic use/stewardship. RESULTS: Incongruent or incomplete guideline UTI definitions were found in 78% (35/45) of videos (K = 0.40), despite 80% (36/45) being authored by HCWs. Forty-two percent (19/45) promoted nonguideline-based hygiene practices; 25% (11/45) advocated front-to-back wiping (K = 0.71). Descriptors identified within the videos included the mention of women with UTI as unclean. Only 55% (25/45) discussed increasing fluid intake (K = 0.59), while 33% (15/45) discussed the use of cranberry supplementation (K = 0.81). CONCLUSIONS: Discussion of hygiene practices which lack a specific guideline statement is particularly evident. Descriptors that characterize women with UTI as "unclean" may create a health equity concern for women experiencing UTIs. These findings should alert HCWs to the scope and emphasis in online education that patients may view to self-educate; both the errors and the issues of equity are problematic. Educational materials on UTI should be based on evidence-based guidelines, such as those by the AUA.

RESUMO

Traditional folk treatments for the prevention and management of urinary tract infections (UTIs) and other infectious diseases often include plants and plant extracts that are rich in phenolic compounds. These have been ascribed a variety of activities, including inhibition of bacterial interactions with host cells. Here, we tested a panel of four well-studied phenolic compounds-caffeic acid phenethyl ester (CAPE), resveratrol, catechin, and epigallocatechin gallate-for the effects on host cell adherence and invasion by uropathogenic Escherichia coli (UPEC). These bacteria, which are the leading cause of UTIs, can bind and subsequently invade bladder epithelial cells via an actin-dependent process. Intracellular UPEC reservoirs within the bladder are often protected from antibiotics and host defenses and likely contribute to the development of chronic and recurrent infections. In cell culture-based assays, only resveratrol had a notable negative effect on UPEC adherence to bladder cells. However, both CAPE and resveratrol significantly inhibited UPEC entry into the host cells, coordinate with attenuated phosphorylation of the host actin regulator Focal Adhesion Kinase (FAK or PTK2) and marked increases in the numbers of focal adhesion structures. We further show that the intravesical delivery of resveratrol inhibits UPEC infiltration of the bladder mucosa in a murine UTI model and that resveratrol and CAPE can disrupt the ability of other invasive pathogens to enter host cells. Together, these results highlight the therapeutic potential of molecules like CAPE and resveratrol, which could be used to augment antibiotic treatments by restricting pathogen access to protective intracellular niches.IMPORTANCEUrinary tract infections (UTIs) are exceptionally common and increasingly difficult to treat due to the ongoing rise and spread of antibiotic-resistant pathogens. Furthermore, the primary cause of UTIs, uropathogenic Escherichia coli (UPEC), can avoid antibiotic exposure and many host defenses by invading the epithelial cells that line the bladder surface. Here, we identified two plant-derived phenolic compounds that disrupt activation of the host machinery needed for UPEC entry into bladder cells. One of these compounds, resveratrol, effectively inhibited UPEC invasion of the bladder mucosa in a mouse UTI model, and both phenolic compounds significantly reduced host cell entry by other invasive pathogens. These findings suggest that select phenolic compounds could be used to supplement existing antibacterial therapeutics by denying uropathogens shelter within host cells and tissues and help explain some of the benefits attributed to traditional plant-based medicines.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Urinary tract infections (UTIs) are globally prevalent infectious diseases, predominantly caused by uropathogenic Escherichia coli (UPEC). The misuse of antibiotics has led to the emergence of several drug-resistant strains. Traditional Chinese Medicine (TCM) has its own advantages in the treatment of UTIs. HJ granules is a herbal formula used for the treatment of UTIs. However, its mechanism of action is not clear. AIM OF THE STUDY: The aim of this study was to investigate the therapeutic efficacy and mechanism of action of HJ granules in a rat model of UTI caused by Escherichia coli (E coli) CFT073. MATERIALS AND METHODS: SD rats were selected to establish a rat UTI model by injecting UPEC strain CFT073 into the bladder using the transurethral placement method. HJ granules were administered to rats after modelling and the efficacy of HJ granule was investigated by measuring urinary decanalogue, inflammatory factors in bladder tissue and pathological changes in the bladder after 3d of administration. Expression of sonic hedgehog (SHH), NOD-like receptor thermoprotein domain 3 (NLRP3), apoptosis-associated speck-like protein (ASC) and activation of cysteinyl aspartate specific proteinase-1 (caspase-1) were detected by western blotting and immunofluorescence staining in rat bladder tissue. NLRP3, ASC and caspase-1, a cysteine-containing aspartic protein, were expressed and activated. RESULTS: The results showed that infection of rats with UPEC resulted in increased pH and erythrocytes in bladder irrigation fluid; increased expression of IL-1ß, IL-6 and SHH and decreased expression of IL-10 in bladder tissue; and significant upregulation of the expression of both SHH and NLRP3 inflammasom and significant activation of NLRP3 inflammasom. HJ granules significantly increased the concentration of IL-10 in the bladder, inhibited the expression of SHH and NLRP3 inflammasom in bladder tissue, and suppressed the activation of NLRP3 inflammasom, thereby reducing inflammatory lesions in bladder tissue. CONCLUSION: HJ granules may improve bladder injury and treat UTIs by inhibiting the expression and activation of NLRP3 inflammasom.

RESUMO

More than 70% of hospital-acquired urinary tract infections are related to urinary catheters, which are commonly used for the treatment of about 20% of hospitalized patients. Urinary catheters are used to drain the bladder if there is an obstruction in the tube that carries urine out of the bladder (urethra). During catheter-associated urinary tract infections, microorganisms rise up in the urinary tract and reach the bladder, and cause infections. Various materials are used to fabricate urinary catheters such as silicone, polyurethane, and latex. These materials allow bacteria and fungi to develop colonies on their inner and outer surfaces, leading to bacteriuria or other infections. Urinary catheters could be modified to exert antibacterial and antifungal effects. Although so many research have been conducted over the past years on the fabrication of antibacterial and antifouling catheters, an ideal catheter needs to be developed for long-term catheterization of more than a month. In this review, we are going to introduce the recent advances in fabricating antibacterial materials to prevent catheter-associated urinary tract infections, such as nanoparticles, antibiotics, chemical compounds, antimicrobial peptides, bacteriophages, and plant extracts.

RESUMO

In northern Australia, a region with limited access to healthcare and a substantial population living remotely, antibiotic resistance adds to the complexity of treating infections. Focussing on Escherichia coli urinary tract infections (UTIs) and Staphylococcus aureus skin & soft tissue infections (SSTIs) captured by a northern Australian antibiotic resistance surveillance system, we used logistic regression to investigate predictors of a subsequent resistant isolate during the same infection episode. We also investigated predictors of recurrent infection. Our analysis included 98,651 E. coli isolates and 121,755 S. aureus isolates from 70,851 patients between January 2007 and June 2020. Following an initially susceptible E. coli UTI, subsequent recovery of a cefazolin (8%) or ampicillin (13%) -resistant isolate during the same infection episode was more common than a ceftriaxone-resistant isolate (2%). For an initially susceptible S. aureus SSTI, subsequent recovery of a methicillin-resistant isolate (8%) was more common than a trimethoprim-sulfamethoxazole-resistant isolate (2%). For UTIs and SSTIs, prior infection with a resistant pathogen was a strong predictor of both recurrent infection and resistance in future infection episodes. This multi-centre study demonstrates an association between antibiotic resistance and an increased likelihood of recurrent infection. Particularly in remote areas, a patient's past antibiograms should guide current treatment choices since recurrent infection will most likely be at least as resistant as previous infection episodes. Using population-level surveillance data in this way can also help clinicians decide if they should switch antibiotics for patients with ongoing symptoms, while waiting for diagnostic results.

RESUMO

OBJECTIVES: Urinary tract infections (UTIs) are very common infections in humans, and Escherichia coli (E. coli) is the commonest pathogen leading to UTIs. The generation of beta-lactamase enzymes in this bacterium results in its resistance against many antibiotics. This study compares three doses of amikacin on alternate days with a daily dose of meropenem in the same period for the treatment of UTIs with E. coli in a double-blind clinical trial. METHODS: The current double-blind clinical trial compares three doses of amikacin on alternate days with a daily dose of meropenem in the same period for the treatment of UTIs with E. coli. The patients were assigned to two groups: Intervention (receiving a single dose of amikacin once a day at 48-h intervals for a week, three doses) and control (receiving meropenem for 1/TDS for a week). RESULTS: The E. coli infection frequency was 61 (21 cases of non-ESBL and 40 cases of ESBL-positive infections) and the frequency of the other infections was 52 (46%). In the patients with ESBL E. coli infection, ciprofloxacin (21; 70%) showed the highest antibiotic resistance, and nitrofurantoin (33; 91.7%) showed the highest sensitivity. The baseline variables between the control and intervention groups indicated no significant difference (p > 0.05). The frequency of signs and symptoms showed no significant difference between the amikacin and meropenem groups in the first 24 h and the first week. In the second week of follow-up, no clinical signs or symptoms were observed in the two groups. CONCLUSION: The results of this study showed that treatment with amikacin, 1 g q48h, for one week (three doses) has the same result as meropenem, 1 g q8h, for one week (21 doses). The results are the same for the treatment of UTIs with ESBL positive and ESBL negative. Amikacin can be used once every 48 h to treat UTIs, is less expensive and can be administered on an outpatient basis. TRIAL REGISTRATION: This study was registered in the Iranian Registry of Clinical Trials (IRCT) with ID number: IRCT20170417033483N2 on the date 2018-02-13.

RESUMO

New and creative methodologies for the fabrication of silver nanoparticles (Ag-NPs), which are exploited in a wide range of consumer items, are of significant interest. Hence, this research emphasizes the biological approach of Ag-NPs through Egyptian henna leaves (Lawsonia inermis Linn.) extracts and analysis of the prepared Ag-NPs. Plant extract components were identified by gas chromatography mass spectrometry (GC-mass). The analyses of prepared Ag-NPs were carried out through UV-visible (UV-Vis), X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscope (SEM), and Fourier transform infrared (FTIR) analysis. UV-Vis reveals that Ag-NPs have a maximum peak at 460 nm in visible light. Structural characterization recorded peaks that corresponded to Bragg's diffractions for silver nano-crystal, with average crystallite sizes varying from 28 to 60 nm. Antibacterial activities of Ag-NPs were examined, and it is observed that all microorganisms are very sensitive to biologically synthesized Ag-NPs.

RESUMO

Standard urine culture is the gold standard for diagnosing urinary tract infections (UTIs) but fails to differentiate true UTI from asymptomatic bacteriuria, which is important to prevent the overuse of antibiotics. Correlation with the presence or absence of pyuria can be helpful in giving a hint of the true situation. With the help of Laboratory Information System (LIS), patients' urinalysis reports can be conveniently accessed and compared simultaneously with appropriate reports. In our study, a quality improvement initiative was planned for appropriate reporting of urine culture and antimicrobial susceptibility testing using information obtained through LIS.

RESUMO

AIMS: In studies utilizing a 20-injection-site paradigm of onabotulinumtoxinA treatment for overactive bladder (OAB), some patients performed clean intermittent catheterization (CIC). An alternative injection paradigm of fewer injections targeting the lower bladder may reduce the need for CIC by maintaining upper bladder function. This study evaluated the efficacy and safety of an unapproved alternative 10-injection-site paradigm targeting the lower bladder. METHODS: In this phase 4, double-blind, parallel-group study, patients with OAB and urinary incontinence (UI) for ≥6 months with ≥3 episodes of urinary urgency incontinence (no more than 1 UI-free day) and ≥8 micturitions per day over 3 days during screening were randomized 2:1 to onabotulinumtoxinA 100 U or placebo injected at 10 sites in the lower bladder. RESULTS: Of 120 patients, 78 in the onabotulinumtoxinA group and 39 in the placebo group had efficacy assessments. In the double-blind phase, mean change from baseline at week 12 in daily frequency of UI episodes was greater with onabotulinumtoxinA (-2.9) versus placebo (-0.3) (least squares mean difference [LSMD]: -2.99, p < 0.0001). Achievement of 100% (odds ratio [OR]: 6.15 [95% confidence interval, CI: 0.75-50.37]), ≥75% (OR: 7.25 [2.00-26.29]), and ≥50% improvement (OR: 4.79 [1.87-12.28]) from baseline in UI episodes was greater with onabotulinumtoxinA versus placebo. Reductions from baseline in the daily average number of micturitions (LSMD: -2.24, p < 0.0001), nocturia (LSMD: -0.71, p = 0.0004), and urgency (LSMD: -2.56, p < 0.0001) were greater with onabotulinumtoxinA than with placebo. Treatment benefit was improved or greatly improved in the onabotulinumtoxinA group (74.0% of patients) versus placebo (17.6%) (OR: 13.03 [95% CI: 3.23-52.57]). Mean change from baseline in Incontinence Quality of Life score was greater with onabotulinumtoxinA versus placebo (LSMD: 24.2, p = 0.0012). Two of 78 (2.6%) patients in the onabotulinumtoxinA group used CIC during the double-blind period; no females used CIC during the double-blind period. Commonly reported adverse events (≥5%) were urinary tract infection (UTI), dysuria, and productive cough for both groups; rate of UTI was higher with onabotulinumtoxinA versus placebo. CONCLUSION: In patients treated with onabotulinumtoxinA for OAB with UI, an unapproved alternative injection paradigm targeting the lower bladder demonstrated efficacy over placebo, with a low incidence of CIC.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Urinary tract infections (UTIs) with pathogenic strain resistance leading to a high recurrence rate affect health quality and have become a high-priority issue due to the economic burden on the health care system. AIM OF THE STUDY: This study aimed to investigate the supportive benefits of traditional herbal medicines (THMs) for the treatment and prevention of recurrent UTIs through a meta-analysis of randomized controlled trials. MATERIALS AND METHODS: Systematic searches of databases, including PubMed/Medline, the Cochrane Library, and China National Knowledge Infrastructure (CNKI), were conducted to collect eligible studies for meta-analysis. The inclusion criteria were randomized controlled trials that investigated UTI recurrence using THM treatment. RESULTS: The results of 22 studies showed that THM treatment led to significantly fewer UTI events in the experimental group than in the control group (OR = 0.348; 95% confidence interval [CI] = 0.257 to 0.473; p < 0.001). Seventeen studies reported UTI events during the follow-up period, and the recurrence rate was lower in the experimental group than in the control group (OR, 0.326; 95% CI, 0.245-0.434; p < 0.01). Subgroup analysis further showed that compared to antibiotics alone, treatment with THM plus antibiotics significantly reduced UTI events in the acute phase (OR = 0.301; 95% CI = 0.201 to 0.431; p < 0.001) as well as in the follow-up period (OR = 0.347; 95% CI = 0.241 to 0.498; p < 0.001). However, THM treatment alone was not superior to antibiotics in the acute treatment phase (OR = 0.540; 95% CI = 0.250 to 1.166; p = 0.117) or in the follow-up period (OR = 0.464; 95% CI = 0.111 to 1.951; p = 0.295). Herbal ingredients for recurrent UTI events also showed benefits compared to placebo treatment in the acute phase (OR = 0.337; 95% CI = 0.158 to 0.717; p = 0.005) and during follow-up (OR = 0.238; 95% CI = 0.139 to 0.409; p < 0.001). CONCLUSIONS: THM combined with antibiotics is helpful for people with acute UTIs and for reinfection prevention. THMs alone, although less effective for recurrent UTIs, could be considered a therapeutic alternative to antibiotics.

RESUMO

BACKGROUND: 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 treating such infections. OBJECTIVES: To assess the effectiveness of cranberries for the treatment of UTIs. SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies up to 1 August 2023 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Portal (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA: All randomised controlled trials (RCTs) or quasi-RCTs of cranberry juice or cranberry products for the treatment of UTIs. Studies of men, women or children were to be included. DATA COLLECTION AND ANALYSIS: Titles and abstracts of studies that were potentially relevant to the review were screened and studies that were clearly ineligible were discarded. Further information was sought from the authors where papers contained insufficient information to make a decision about eligibility. MAIN RESULTS: No studies were found that fulfilled all of our inclusion criteria. Seven studies were excluded because they were the wrong study design, mixed interventions or did not report any relevant outcomes. One study is ongoing; however, its current status is unknown. AUTHORS' CONCLUSIONS: After a thorough search, no RCTs which assessed the effectiveness of cranberry juice for the treatment of UTIs were found. Therefore, at the present time, there is no good quality evidence to suggest that it is effective for the treatment of UTIs. Well-designed parallel-group, double-blind studies comparing cranberry juice and other cranberry products versus placebo to assess the effectiveness of cranberry juice in treating UTIs are needed. Outcomes should include a reduction in symptoms, sterilisation of the urine, side effects and adherence to therapy. The dosage (amount and concentration) and duration of therapy should also be assessed. Consumers and clinicians will welcome the evidence from these studies.

RESUMO

OBJECTIVE: This study was designed to determine the effect of cranberry extract used in patients with single urinary tract infections. METHODS: Patients with simple-type urinary tract infections were divided into two groups. Treatment with fosfomycin or cranberry tablet was started. On days 1, 3, and 7 of the treatment, whether there was a decrease in the complaints was evaluated with a Likert-type scale. The recovery status of urinary tract infections and the well-being of patients were compared via antibiotic and cranberry groups. RESULTS: After the treatment, the leukocyte levels of the cranberry users were at the same level as those of the other group, and the rate of well-being and the portion of patients that reported to be "very well" on days 3 and 7 in the cranberry group was significantly higher compared with the fosfomycin group (p<0.05). CONCLUSION: Considering the results of this study, it was determined that the patient's complaints decreased from day 3 and their well-being increased with the use of cranberry only. Specifically, on day 7, the well-being of the cranberry group was higher than that of the fosfomycin group. For this reason, cranberry is a favorable alternative to antibiotics in uncomplicated and simple urinary tract infections.

RESUMO

Lower urinary tract infections (LUTI) are one of the most common urological diseases. Prevention of recurrences and development of chronic cystitis are among the key tasks in the treatment of women with LUTI. It consists of choosing adequate antibacterial therapy and preventive measures. Phytotherapy using various herbal preparations is considered to be one of the most common and effective preventive measure. Three clinical cases of effective treatment of patients with recurrent LUTI with Phytolysin paste and Phytolysin capsules as part of complex therapy are presented in the article, demonstrating the high efficiency of long-term courses of phytotherapy.

RESUMO

BACKGROUND: The problem of recurrent urinary tract infections (UTI) in patients with type 2 diabetes mellitus (DM 2) is relevant, especially when there is a combination of predisposing factors, such as female gender, history of UTI episodes, and therapy with sodium glucose cotransporter type 2 (SGLT-2) inhibitors, and the choice of effective and safe means could cause some difficulties, including ina terms of the burden of antibiotic resistance. AIM: To evaluate the effectiveness and safety of the phytoproduct Canephron® N for the prevention of exacerbations of recurrent cystitis and the effect on metabolic parameters in patients with type 2 diabetes taking SGLT-2 inhibitors. MATERIALS AND METHODS: Prospective, randomized, open, parallel group study in 60 women. The main group took the drug Canephron® N for 3 months. The main parameters for evaluating were the frequency of recurrence of cystitis, level of albuminuria and LDL-cholesterol peroxidation product - malondialdehyde. RESULTS: Within 3 months of taking Canephron® N, exacerbations of chronic cystitis were diagnosed 2 times less often, a decrease in albuminuria was found in the form of an increase in the proportion of patients with an optimal level of albuminuria by 20%, a 50% reduction in the frequency of the initial increase in albuminuria, and the absence of moderate albuminuria in all patients at the end of course of therapy. A decrease in the level of MDA by 1.4 times was noted (p=0.019). CONCLUSION: Thus, the herbal drug Canephron® N can be used for accompanying therapy and prophylactic treatment in patients with recurrent cystitis on the background of DM 2, taking SGLT-2 inhibitors. The course of therapy should last at least 3 months.
