(Moderate Recommendation; Evidence Level: Grade B) There is limited high quality up to date evidence of comparative trials on the length of antibiotic therapies for complete resolution of UTI symptoms. Other gram-negative rods, including Serratia, Morganella, Citrobacter, Enterobacter, Acinetobacter, and Pseudomonas, are found in patients with previous health care and antimicrobial exposure. This guideline does not apply to pregnant women, patients who are immunocompromised, those with anatomic or functional abnormalities of the urinary tract, women with rUTIs due to self-catheterization or indwelling catheters or those exhibiting signs or symptoms of systemic bacteremia, such as fever and flank pain. Continued documentation of cultures during symptomatic periods prior to instituting antimicrobial therapy helps to provide a baseline against which interventions can be evaluated, to determine the appropriate pathway within the treatment algorithm, and to allow for the tailoring of therapy based on bacterial antimicrobial sensitivities.One propensity-matched cohort study (n=48,283) found that among women with rUTI, obtaining a urine culture >50% of the time was associated with decreased risk of hospitalization (OR 0.79, 95% CI 0.67 to 0.93) and intravenous antibiotics (OR 0.91, 95% CI 0.86 to 0.97). Generally, such organisms are susceptible only to carbapenems. Hooton, TM, Bradley, SF, Cardena, DD. Regional resistance thresholds are 20% for TMP-SMX and 10% for FQ, above which these agents should not be used alone to empirically treat UTI. (Strong Recommendation; Evidence Level: Grade B)9. This can occur with pathogens such as S. aureus, Candida sp., and Salmonella. The Panel does recognize, however, that certain clinical scenarios, such as planned surgical intervention in which mucosal bleeding is anticipated, may prompt screening.
The overall 28-day and 1-year all-cause mortality rates following a UTI associated with gram-negative bacteremia was found to be 4.9% (95% confidence interval [CI]: 3.0-6.8) and 15.6% (95% CI: 12.4-18.8), respectively, in a population-based retrospective study. When making a diagnosis of complicated UTI on the basis of systemic symptoms alone, other diagnoses need to be excluded. What is the estimated resistance prevalence for uropathogens (primarily Escherichia coli) in the region? This strategy is not effective long-term because of issues of antibiotic resistance and adverse effects. (Moderate Recommendation; Evidence Level: Grade B)rUTI is a highly prevalent, costly, and burdensome condition affecting women of all ages, races, and ethnicities without regard for socioeconomic status, or educational level.For the purposes of this guideline, the Panel considers only recurrent episodes of uncomplicated cystitis in women. Clinicians should not perform a post-treatment test of cure urinalysis or urine culture in asymptomatic patients. (Moderate Recommendation; Evidence Level: Grade B) For evidence-based treatment of rUTIs, a large body of evidence exists in support of antibiotic prophylaxis. Imaging for fungus balls, abscesses, or other abnormalities should be performed in patients with recurrent candidal UTI, severe UTI, or acute changes in renal function.
Cranberry, in a formulation that is available and tolerable to the patient, may be offered as prophylaxis including oral juice and tablet formulations as there is not sufficient evidence to support one formulation over another when considering this food-based supplement. Patients with pyelonephritis or complicated UTI should undergo imaging of the urinary tract in the following settings: The presentation is usually fever with specific cystitis symptoms and gross hematuria. Clinicians should not treat ASB in patients. However, the IDSA guidelines introduced the concepts of in vitro resistance prevalence and ecological adverse effects of antimicrobial therapy or collateral damage as key considerations in choosing UTI treatments.Clinicians should treat rUTI patients experiencing acute cystitis episodes with as short a duration of antibiotics as reasonable, generally no longer than seven days. Since even UTI experts sometimes conflate complicated with severe or invasive when referring to UTI [1, 3], there is little reason to expect that nonexperts will be able to consistently make this critical distinction, which has huge implications for patient management. After dual review of abstracts and titles, 214 systematic reviews and individual studies were selected for full-text dual review, and 65 studies in 67 publications were determined to meet inclusion criteria and were included in this review. In a prospective observational study of the diagnostic yield of intravenous urography (IVU) with respect to referral source and presenting features, 91.7% of patients presenting with rUTI had normal IVU.Clinicians should obtain urinalysis, urine culture and sensitivity with each symptomatic acute cystitis episode prior to initiating treatment in patients with rUTIs. Microbial confirmation at the time of acute-onset urinary tract-associated symptoms and signs, which primarily include dysuria, urinary frequency and urgency, new or worsening incontinence with or without gross hematuria, is a critical component to establish a diagnosis of rUTI. Vaginal estrogen therapy has not been shown to increase risk of cancer recurrence in women undergoing treatment for or with a personal history of breast cancer. Initial treatment should include reduction in immunosuppression where possible. It should again be emphasized that symptom clearance is sufficient. (Moderate Recommendation; Evidence Level: Grade C)In select circumstances, employing a shared decision-making process with informed patients, initiation of a short treatment course of antibiotic therapy at the discretion of the patient (self-start) therapy may be offered for acute symptomatic episodes in patients with diagnosis of rUTI. “Enterococcus faecalis clones in poultry and in humans with urinary tract infections, Vietnam”.
