Xyloglucan, Hibiscus and Propolis in the Management of Uncomplicated Lower Urinary Tract Infections: A Systematic Review and Meta-Analysis

Background: In the era of antibiotic resistance, an antibiotic-sparing approach presents an interesting alternative treatment of uncomplicated cystitis in women. Our aim is to perform a systematic review and meta-analysis to compare the effectiveness and safety profile of a medical device containing xyloglucan, hibiscus and propolis (XHP) in women with uncomplicated cystitis. Methods: Relevant databases were searched using methods recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The primary endpoint was clinical or microbiological success, defined as the complete (cure) and/or non-complete (improvement) resolution of symptoms at the end of treatment, or microbiological resolutions. Results: After screening 21 articles, three studies were included, recruiting a total of 178 patients. All three studies used placebo as comparator. A statistically significant difference was found in terms of clinical or microbiological resolution between the medical device and the comparator (3 RCTs, 178 patients, OR: 0.13; 95% CI: 0.05–0.33; p < 0.0001). No clinically significant adverse effects have been reported. Conclusion: A medical device containing xyloglucan, hibiscus and propolis is superior to comparator regimens in terms of clinical effectiveness in adult women with microbiologically confirmed or clinical suspicion of uncomplicated cystitis and is associated with a high patient compliance.

Antimicrobial Prescription Practices for Outpatients with Cystitis: A Multicenter, Medical Record-Based Study

To promote antimicrobial stewardship (AMS) and appropriate antibiotic use, we studied antimicrobial prescription rates for uncomplicated cystitis, a common outpatient disease requiring antibiotic treatment in Japan. This multicenter retrospective study was performed from January 1, 2018, to December 31, 2020, targeting outpatients aged ≥20 years whose medical records revealed International Classification of Diseases (ICD-10) codes suggesting uncomplicated cystitis (N300). We divided eligible cases into two age groups (20–49 years and ≥50 years) and defined broad-spectrum antimicrobials as fluoroquinolones, third-generation cephalosporins, and faropenem. Primary and secondary outcomes were defined as the prescription rates of broad-spectrum antimicrobials for the disease and the association of antimicrobial types with recurrence. The data of 1,445 patients were collected and that of 902 patients were analyzed. The overall proportion of broad-spectrum antimicrobial prescriptions was 69.1%. The broad-spectrum agents were prescribed frequently in the older group, male patients, and internal medicine. Recurrence was observed in 37 (4.1%) cases, and age, sex, or antimicrobial types were not associated with the recurrence. Hence, approximately two-thirds of antimicrobials prescribed for uncomplicated cystitis were broad-spectrum agents. Administration of broad-spectrum antimicrobials was not associated with the prevention of the recurrence of cystitis.

The Effect of Sociodemographic Factors, Parity and Cervical Cancer on Antibiotic Treatment for Uncomplicated Cystitis in Women: A Nationwide Cohort Study

Background: Uncomplicated cystitis is one of the most common reasons for antibiotic treatment in otherwise healthy women. Nationwide studies on antibiotic treatment for this infection and in relation to factors beyond the infection itself have hitherto not been available. Methods: This was a nationwide open cohort study consisting of 352,507 women aged 15–50 years with uncomplicated cystitis (2006–2018). The outcome was a redeemed antibiotic prescription within five days from the cystitis diagnosis. Logistic regression models were used to examine the relationship between the outcome and the predictor variables. Results: This study identified 192,065 redeemed treatments (54.5%). Several sociodemographic variables were associated with antibiotic treatment. For example, women with the lowest income had an odds ratio (OR) of 1.26 (95% CI 1.23–1.28) compared to those with the highest income. History of cervical cancer and high parity were also associated with lower treatment rates. Conclusion: This study presents novel factors beyond the infection which seem to affect the antibiotic treatment for uncomplicated cystitis in women. Future studies to investigate possible mechanisms are warranted in order to properly use our findings. This may help healthcare workers and planners to provide a more equal treatment plan for this common infection, which may reduce misuse of antibiotics, decrease costs and improve efforts against antibiotic resistance.

1421. Empiric Fluoroquinolone Prescribing Trends for Cystitis in Primary Care

Background Understanding outpatient antibiotic prescribing practices for urinary tract infections (UTIs) is vital in guiding future stewardship initiatives. Focusing on fluoroquinolones (FQs) is of value as FQs are commonly prescribed, but not recommended as first line therapy by the Infectious Diseases Society of America (IDSA) cystitis treatment guidelines and are also associated with multiple adverse effects. Boxed warnings state FQs should be reserved for patients with no alternative treatment options, due to risk of aortic dissection, C. difficile infection, antimicrobial resistance as well as tendon, joint, muscle, and nervous system damage. Methods This descriptive study assessed rates of guideline concordant empiric FQ prescribing from March 1 to June 30, 2019. Adult women prescribed an oral FQ for acute uncomplicated cystitis at a primary care clinic were included. Men, pregnant or breastfeeding women, and patients with pyelonephritis, urologic abnormality, or antibiotic use in the past 30 days were excluded. The primary outcome was the incidence of IDSA guideline concordance among FQs empirically prescribed. Guideline concordant empiric FQ therapy was defined as correct drug, dose, duration and frequency per IDSA guidelines when no first line drug is indicated due to allergy, adverse effect, previous treatment failure or most recent previous urine culture showing bacterial resistance. Secondary outcomes were mean dose (mg), mean duration (days) and incidence of adverse effects. Results Of 95 FQ prescriptions included, none met the primary outcome definition. Rates of guideline concordance for each component of the primary outcome definition were 6% for drug selection, 38% for dose, 37% for duration, and 99% for frequency. Mean daily doses exceeded guideline recommended doses by 62% and 100% for ciprofloxacin and levofloxacin, respectively. Mean duration was 5 days, 66% longer than 3 days as recommended by IDSA guidelines. Of 66 patients with documented follow up within 30 days, 3 (5%) experienced an adverse effect, and none developed C. difficile infection. Conclusion Current outpatient FQ prescribing for acute uncomplicated cystitis does not align with IDSA guidelines. Multifaceted antimicrobial stewardship initiatives are required to improve appropriate FQ use. Disclosures All Authors: No reported disclosures

General principles of uncomplicated cystitis therapy during pregnancy

Urinary tract infections during pregnancy are associated with severe complications. Earlier initiation of antibiotic treatment for acute uncomplicated cystitis, reduces the various complications.Objective. To assess the effectiveness of fosfomycin in the treatment of acute uncomplicated cystitis during II and III trimester of pregnancy.Material and methods. The study included 74 pregnant women who had acute uncomplicated cystitis in II or III trimesters. All patients received fosfomycin trometamol 3.754 g (equivalent to 3 g fosfomycin) as antimicrobial therapy for acute uncomplicated cystitis. The drug was prescribed to 24 pregnant women in the II, and 50 in the III trimester of pregnancy.Results. After treatment with fosfomycin signs of acute cystitis gone in all patients. At the same time, regression of clinical symptoms was noted during the next days after therapy in 95.9% (n = 71) of cases. Repeated microbiological test of the middle portion of urine was performed 7 days after the end of antibiotic therapy. In 94.6% (n = 70) cases, total elimination of the pathogen was achieved. In 5.4% (n = 4) cases, there was a significant decrease of colonization Follow-up for three months showed the absence of recurrence of acute cystitis in all pregnant women who were included in the study.Conclusion. Fosfomycin is a highly effective drug in the treatment of uncomplicated cystitis during pregnancy.

Case-based audit and feedback around a decision aid improved antibiotic choice and duration for uncomplicated cystitis in primary care clinics

ObjectivesThe objective of our study was to evaluate the impact of a multifaceted stewardship intervention on adherence to the evidence-based practice guidelines on treatment of uncomplicated cystitis in primary care. We hypothesised that our intervention would increase guideline adherence in terms of antibiotic choice and duration of treatment.DesignA preintervention and postintervention comparison with a contemporaneous control group was performed. During the first two study periods, we obtained baseline data and performed interviews exploring provider prescribing decisions for cystitis at both clinics. During the third period in the intervention clinic only, the intervention included a didactic lecture, a decision algorithm and audit and feedback. We used a difference-in-differences analysis to determine the effects of our intervention on the outcome and guideline adherence to antibiotic choice and duration.SettingTwo family medicine clinics (one intervention and one control) were included.ParticipantsAll female patients with uncomplicated cystitis attending the study clinics between 2016 and 2019.ResultsOur sample included 932 visits representing 812 unique patients with uncomplicated cystitis. The proportion of guideline-adherent antibiotic regimens increased during the intervention period (from 33.2% (95% CI 26.9 to 39.9) to 66.9% (95% CI 58.4 to 74.6) in the intervention site and from 5.3% (95% CI 2.3 to 10.1) to 17.0% (95% CI 9.9 to 26.6) in the control site). The increase in guideline adherence was greater in the intervention site compared with the control site with a difference-in-differences of 22 percentage points, p=0.001.ConclusionA multifaceted intervention increased guideline adherence for antibiotic choice and duration in greater magnitude than similar trends at the control site. Future research is needed to facilitate scale-up and sustainability of case-based audit and feedback interventions in primary care.

Uncomplicated urinary tract infection in the practice of a internist (clinical analysis)

Urinary tract infections remain one of the most common problems of modern medicine. In this regard, not only urologists, but also specialists of other specialties face urinary tract infection in their practice: internists, general practitioners, obstetricians and gynecologists. The growing resistance of uropathogs to antibiotics dictates the need for constant revision of the principles of antibacterial therapy of urinary tract infections. The article presents an analysis of two clinical cases: a sporadic episode of acute uncomplicated cystitis and an episode of recurrent urinary tract infection. The principles of modern diagnostics and therapeutic strategy are considered.
