One in three women has had at least one urinary tract infection (UTI) treated with antibiotics by the age of 24 years, and half of all women experience a UTI in their lifetime with one in four developing recurrence. Recurrent UTI is defined by two or more symptomatic infections in the past 6 months or three or more symptomatic infections in the past 12 months where each UTI follows a complete resolution of the previous UTI. This review describes the risk factors, diagnosis, work-up and treatment, and prevention of recurrent UTIs. Prevention strategies can be divided into antimicrobial and nonantimicrobial strategies. Nonantimicrobial prevention with behavioral changes, cranberry products, or probiotics did not significantly reduce the occurrence of symptomatic UTIs. Compared with placebo, oral estrogens did not reduce UTIs. However, vaginal estrogens do play a role in prevention of recurrence, particularly in postmenopausal women. There are three main strategies for antibiotic prevention: (1) low-dose daily antimicrobial prophylaxis, (2) postcoital antimicrobial prophylaxis, and (3) patient-initiated antimicrobial treatment. All of these strategies decrease infections during prophylaxis period.The choice of regimen should be based on susceptibilities and antibiotic allergy. This review contains 1 figure, 7 tables and 37 references.

Abstract Background Urinary tract infections (UTIs) are frequently caused by Enterococcus spp. We aim to define the risk factors involved in UTIs caused by Enterococcus. Determine the overall mortality and predictive risk factors. Methods A retrospective in-patients study was conducted with bacteriemic UTIs caused by Enterococcus spp. We compared bacteriemic UTIs caused by Enterococcus spp. vs. a random sample of 100 in-patients with bacteriemic UTIs caused by others enterobacteria. Results We found 106 in-patients with UTIs caused by Enterococcus spp., 51 of whom had concomitant positive blood cultures. Distribution by species was: 83% E. faecalis and 17% E. faecium, with a Charlson comorbidity index of 5.9 ± 2.9. When we compared bacteriemic UTIs caused by Enterococcus spp. vs. bacteriemic UTIs caused by others enterobacteria we found the following independent predictors of bacteriemic UTI by Enterococcus: male sex with an OR of 6.1 (95%CI 2.3–16.1), uropathy with an OR of 4.1 (1.6–10.1), nosocomial infection with an OR of 3.8 (1.4–10.3), urinary cancer with an OR of 6.4 (1.3–30.3) and previous antimicrobial treatment with an OR of 18 (5.2–62.1). Overall, in-patient mortality was 16.5%, which was associated with a higher Sequential Organ Failure Assessment (SOFA) score (> 4), severe comorbidity such as immunosuppression, malignant hemopathy and nephrostomy, or Enterococcus faecium species and its pattern or resistance to ampicillin or vancomycin (p < 0.05). Appropriate empiric antibiotic therapy was not associated with a better prognosis (p > 0.05). Conclusions Enterococcus spp. is a frequent cause of complicated UTI by a profile of risk factors. High mortality secondary to a severe clinical setting and high comorbidity may be sufficient reasons for implementing empiric treatment of patients at risk, although we did not show a higher survival rate in patients with this treatment strategy.

Urinary tract infection (UTI) is the most common bacterial infection, affecting women far more than men. Aerobic gram-negative bacteria are the most common uropathogens causing UTI, with Escherichia coli remaining the most predominant organism in complicated infections. UTI can result in a variety of infections and inflammations, from asymptomatic bacteriuria to typical symptomatic cystitis to acute pyelonephritis, as well as bacterial prostatitis in men. In general, antimicrobial therapy is warranted for any symptomatic infection of the urinary tract. However, new consensus treatment guidelines for uncomplicated UTI in women, set by the Infectious Diseases Society of America and the European Society for Microbiology of Infection Diseases in 2010, account for the increasing antimicrobial resistance of pathogens and focus on first-line empirical treatment regimens. To reduce the use of antibiotics, treatment and prevention of recurrent UTI may involve several strategies on varying levels of effectiveness; some of the more well-tested options include probiotics, antiseptics, and topical estrogen. Antimicrobial approaches should be reserved for women in whom these options prove to be ineffective. This review contains 7 figures, 10 tables, and 122 references.

Tract Infections

Urinary Tract Infections (UTIs) are amongst the most common infectious diseases and carry a significant impact on patient quality of life and health care costs. Despite that, there is no well-established recommendation for a “standard” prophylactic antibiotic management to prevent UTI recurrences. The majority of patients undergoes long-term antibiotic treatment that severely impairs the normal microbiota and increases the risk of development of multidrugresistant microorganisms. In this scenario, the use of phytotherapy to both alleviate symptoms related to UTI and decrease the rate of symptomatic recurrences is an attractive alternative. Several recently published papers report conflicting findings and cannot give confident recommendations for the everyday clinical practice. A new approach to the management of patients with recurrent UTI might be to use nutraceuticals or phytotherapy after an accurate assessment of the patient`s risk factors. No single compound or mixture has been identified so far as the best preventive approach in patients with recurrent UTI. We reviewed our non-antibiotic approach to the management of recurrent UTI patients in order to clarify the evidence-base for the commonly used substances, understand their pharmacokinetics and pharmacodynamics in order to tailor the best way to improve patient’s quality of life and reduce the rate of antibiotic resistance. Lack of a gold-standard recommendation and the risk of increasing antibiotic resistance is the reason why we need alternatives to antibiotics in the management of urinary tract infections (UTIs). A tailored approach according to bacterial characteristics and the patient risk factors profile is a promising option.

Abstract Purpose: Complicated urinary tract infections (UTIs) are frequently caused by Enterococcus spp. We aim to define the risk factors involved in UTIs caused by Enterococcus. Determine the overall mortality and predictive risk factors.Methods: A retrospective study was conducted. We compared the results with those of a random sample of patients with complicated UTIs infection caused by Escherichia coli.Results: We found 106 in-patients with UTIs caused by Enterococcus spp., 56 of whom had positive blood cultures. Distribution by species: 83% E. faecalis and 17% E. faecium, with a Charlson comorbidity index of 5.9±2.9. Only male sex with an OR of 2.8 (95%CI 1.2-6.4), nosocomial infection with an OR of 2.8 (95%CI 1.1-7), urinary catheter with an OR of 4.5 (95%CI 1.8-11.3), urinary cancer with an OR of 6.4 (2.1-19.4), and previous antimicrobial treatment with an OR of 4.3 (1.8-10.2) were independent predictors of Enterococcus infection. Overall, in-patient mortality was 16.5%, which was associated with a higher Sequential Organ Failure Assessment (SOFA) score (>4), severe comorbidity such as immunosuppression, malignant hemopathy and nephrostomy, or Enterococcus faecium species and its pattern or resistance to ampicillin or vancomycin (p<0.05).

Abstract The kidneys and the urinary tract are a common source of infection in children of all ages, especially infants and young children. The main risk factors for sequelae after urinary tract infections (UTI) are congenital anomalies of the kidney and urinary tract (CAKUT) and bladder-bowel dysfunction. UTI should be considered in every child with fever without a source. The differentiation between upper and lower UTI is crucial for appropriate management. Method of urine collection should be based on age and risk factors. The diagnosis of UTI requires urine analysis and significant growth of a pathogen in culture. Treatment of UTI should be based on practical considerations regarding age and presentation with adjustment of the initial antimicrobial treatment according to antimicrobial sensitivity testing. All children, regardless of age, should have an ultrasound of the urinary tract performed after pyelonephritis. In general, antibiotic prophylaxis is not recommended. Conclusion: Based on recent data and in line with international guidelines, multidisciplinary Swiss consensus recommendations were developed by members of Swiss pediatric infectious diseases, nephrology, and urology societies giving the clinician clear recommendations in regard to diagnosis, type and duration of therapy, antimicrobial treatment options, indication for imaging, and antibiotic prophylaxis. What is Known:• Urinary tract infections (UTI) are a common and important clinical problem in childhood. Although children with pyelonephritis tend to present with fever, it can be difficult on clinical grounds to distinguish cystitis from pyelonephritis, particularly in young children less than 2 years of age.• Method of urine collection is based on age and risk factors. The diagnosis of UTI requires urine analysis and significant growth of a pathogen in culture. What is New:• Vesicoureteric reflux (VUR) remains a risk factor for UTI but per se is neither necessary nor sufficient for the development of renal scars. Congenital anomalies of the kidney and urinary tract (CAKUT) and bladder-bowel dysfunction play a more important role as causes of long-term sequelae. In general, antibiotic prophylaxis is not recommended.• A switch to oral antibiotics should be considered already in young infants. Indications for invasive imaging are more restrictive and reserved for patients with abnormal renal ultrasound, complicated UTI, and infections with pathogens other than E. coli.

Background: Urinary tract infection is common with health impact in women and characterised by failure to treatment and recurrent episodes. Aim: This study was conducted to determine the risk factors for the development of urinary tract infection in diabetic and pregnant women in comparison to student female. Materials and methods: A prospective cross-sectional study conducted during the period from 1st of June 2015 to the end of January 2016. The population included in the study are 563 women, of them 425 were outpatients, and 138 were inpatients. Their age range between 18 and 80 years, with a mean age of 33.59±15.29 years. Urine samples collected and cultured on blood agar and MacConkey agar by spread plate technique. Bacterial colonies with different morphology were selected, purified and identified according to their biochemical characteristics using conventional standard methods. Results: In diabetic women, there were no significant difference in mean age and BMI values between culture positive and culture negative groups. However, pus cell mean scale was significantly higher [P=0.000] in women with urinary tract infection [1.76±1.25] than in those with negative culture [0.69±1.00]. In pregnant women, BMI mean value was significantly [P=0.013] lower in pregnant women with UTI [26.14] as compared to those without infection [26.99]. Pus cell scale mean value was significantly [P=0.000] higher in pregnant women with UTI [1.55] than women with negative UTI [0.85]. While there was no significant difference in mean age between UTI positive and negative pregnant women. In female student, there was a significant difference between UTI infected and non-infected in mean age [P=0.041] and pus cell scale [P=0.000]. However, BMI was not significantly different between infected and non-infected female student. Other risk factors association are variables in the 3 groups when analysed using X2, while AUC and OR show different trends of association between risk factors and UTI. Conclusion: BMI, pus cell scale, child number, delivery method, operation history and hospital setting were significantly associated with culture positivity in the 3 studied groups as determined by AUC. While OR confirmed association with pus sale scale in the 3 groups.
