Symptomatic treatment (using NSAIDS) versus antibiotics in uncomplicated lower urinary tract infection: a meta-analysis and systematic review of randomized controlled trials

Effects of a multimodal intervention in primary care to reduce second line antibiotic prescriptions for urinary tract infections in women: parallel, cluster randomised, controlled trial

OBJECTIVES

To evaluate whether a multimodal intervention in general practice reduces the proportion of second line antibiotic prescriptions and the overall proportion of antibiotic prescriptions for uncomplicated urinary tract infections in women.

DESIGN

Parallel, cluster randomised, controlled trial.

SETTING

General practices in five regions in Germany. Data were collected between 1 April 2021 and 31 March 2022.

PARTICIPANTS

General practitioners from 128 randomly assigned practices.

INTERVENTIONS

Multimodal intervention consisting of guideline recommendations for general practitioners and patients, provision of regional data for antibiotic resistance, and quarterly feedback, which included individual first line and second line proportions of antibiotic prescribing, benchmarking with regional or supra-regional practices, and telephone counselling. Participants in the control group received no information on the intervention.

MAIN OUTCOME MEASURES

Primary outcome was the proportion of second line antibiotics prescribed by general practices, in relation to all antibiotics prescribed, for uncomplicated urinary tract infections after one year between the intervention and control group. General practices were randomly assigned in blocks (1:1), with a block size of four, into the intervention or control group using SAS version 9.4; randomisation was stratified by region. The secondary outcome was the prescription proportion of all antibiotics, relative within all cases (instances of UTI diagnosis), for the treatment of urinary tract infections after one year between the groups. Adverse events were assessed as exploratory outcomes.

RESULTS

110 practices with full datasets identified 10 323 cases during five quarters (ie, 15 months). The mean proportion of second line antibiotics prescribed was 0.19 (standard deviation 0.20) in the intervention group and 0.35 (0.25) in the control group after 12 months. After adjustment for preintervention proportions, the mean difference was -0.13 (95% confidence interval -0.21 to -0.06, P<0.001). The overall proportion of all antibiotic prescriptions for urinary tract infections over 12 months was 0.74 (standard deviation 0.22) in the intervention and 0.80 (0.15) in the control group with a mean difference of -0.08 (95% confidence interval -0.15 to -0.02, P<0.029). No differences were noted in the number of complications (ie, pyelonephritis, admission to hospital, or fever) between the groups.

CONCLUSIONS

The multimodal intervention in general practice significantly reduced the proportion of second line antibiotics and all antibiotic prescriptions for uncomplicated urinary tract infections in women.

A story of the potential effect of non-steroidal anti-inflammatory drugs (NSAIDs) in Parkinson's disease: beneficial or detrimental effects

Parkinson's disease (PD) is an advanced neurodegenerative disease (NDD) caused by the degeneration of dopaminergic neurons (DNs) in the substantia nigra (SN). As PD is an age-related disorder, the majority of PD patients are associated with musculoskeletal disorders with prolonged use of analgesic and anti-inflammatory agents, such as non-steroidal anti-inflammatory drugs (NSAIDs). Therefore, NSAIDs can affect PD neuropathology in different ways. Thus, the objective of the present narrative review was to clarify the potential role of NSAIDs in PD according to the assorted view of preponderance. Inhibition of neuroinflammation and modulation of immune response by NSAIDs could be an effective way in preventing the development of NDD. NSAIDs affect PD neuropathology in different manners could be beneficial or detrimental effects. Inhibition of cyclooxygenase 2 (COX2) by NSAIDs may prevent the development of PD. NSAIDs afforded a neuroprotective role against the development and progression of PD neuropathology through the  modulation of neuroinflammation. Though, NSAIDs may lead to neutral or harmful effects by inhibiting neuroprotective prostacyclin (PGI2) and accentuation of pro-inflammatory leukotrienes (LTs). In conclusion, there is still a potential conflict regarding the effect of NSAIDs on PD neuropathology.

The Clinical Trial Outcomes of Cranberry, D-Mannose and NSAIDs in the Prevention or Management of Uncomplicated Urinary Tract Infections in Women: A Systematic Review

The use of antibiotics in the treatment of UTIs is contributing to resistance. Hence, the outcome of human clinical trials of nonantibiotic remedies for preventing or treating UTI is of significant interest. This systematic review aimed to identify, summarise and evaluate the evidence for the outcomes of different nonantibiotic options including cranberry, D-mannose and non-steroidal anti-inflammatory drugs (NSAIDs). PubMed, Embase and Scopus were searched for manuscripts relating to nonantibiotic treatment of UTI including cranberry, mannose and NSAIDs. After title and abstract screening, data were extracted from 21 papers that were published in English and related to the treatment or prevention of uncomplicated UTI in adult women. We identified twelve papers examining the effects of cranberry, two papers examining D-mannose, two papers examining combination treatments (cranberry and D-mannose) and five manuscripts investigating the effects of NSAIDs. There is low-level evidence, from a small number of studies, supporting the use of D-mannose or combination treatments for potentially preventing UTIs in adult women without producing burdening side effects. However, larger and more randomised double-blinded trials are needed to confirm this. In comparison, the multiple studies of cranberry and NSAIDs produced conflicting evidence regarding their effectiveness.

The Risk of Pyelonephritis Following Uncomplicated Cystitis: A Nationwide Primary Healthcare Study

BACKGROUND

The risk of pyelonephritis following uncomplicated lower urinary tract infection (cystitis) in women has not been studied in well-powered samples. This is likely due to the previous lack of nationwide primary healthcare data. We aimed to examine the risks of pyelonephritis following cystitis in women and explore if antibiotic treatment, cervical cancer, parity, and sociodemographic factors are related to these risks.

METHODS

This was a nationwide cohort study (2006-2018) of 752,289 women diagnosed with uncomplicated cystitis in primary healthcare settings. Of these, 404 696 did not redeem an antibiotic prescription within five days from cystitis. Logistic regression models were used to calculate odds ratios for pyelonephritis within 30 days and 90 days following the cystitis event.

RESULTS

Around one percent (7454) of all women with cystitis were diagnosed with pyelonephritis within 30 days, of which 78.2% had not redeemed an antibiotic for their cystitis. Antibiotic treatment was inversely associated with both outpatient registration and hospitalization due to pyelonephritis, with odds ratios of 0.85 (95% CI 0.80 to 0.91) and 0.65 (95% CI 0.55 to 0.77), respectively. Sociodemographic factors, parity, and cervical cancer were, with few exceptions (e.g., age and region of residency), not associated with pyelonephritis.

CONCLUSIONS

Antibiotic treatment was inversely associated with pyelonephritis, but the absolute risk reduction was low. Non-antibiotic treatment for cystitis might be a safe option for most women. Future studies identifying the women at the highest risks will help clinicians in their decision making when treating cystitis, while keeping the ecological costs of antibiotics in mind.

Intestinal Microbiota Correction in the Treatment and Prevention of Urinary Tract Infection

Intestinal microbiota is a topical subject of modern research. The maintenance of a healthy intestinal micro biota is an important component of homeostasis, and violations of its composition and functions, called dysbiosis, are associated with a number of diseases, including urinary tract infections. Antimicrobial therapy leads to significant changes in the intestinal microbiota and causes the possibility of urinary tract infection recurrence. In this regard, it is important to study methods of microbiota correction in order to restore its structural and functional integrity.

Compliance to Guidelines in Prescribing Empirical Antibiotics for Individuals with Uncomplicated Urinary Tract Infection in a Primary Health Facility of Ghana, 2019-2021

Increasing trends in antimicrobial resistance among uropathogens call for rational use of empirical antibiotics for managing uncomplicated urinary tract infections (UTIs). In Ghana, standard treatment guidelines (STGs) for UTI recommend oral ciprofloxacin or cefuroxime for 5-7 days in females and 10-14 days in males. We conducted a cross-sectional audit using electronic medical records (EMR) to assess compliance to the STGs among adults (≥18 years) with uncomplicated UTIs diagnosed in a primary health facility between October 2019 and October 2021. Among 3717 patients, 71% were females and all had complete prescription details in the EMR. Of all the patients, 83% were prescribed empirical antibiotics, of whom 88% received oral ciprofloxacin or cefuroxime. Only 68% were prescribed antibiotics for the correct duration, which was significantly lower among males (10%) compared to females (90%). Among patients who received antibiotics, 60% were prescribed in line with the STGs. The results call for feedback to physicians about poor compliance to STGs with duration of antibiotic prescribed. Recommendations on 10-14 days duration of antibiotics for males needs to be reassessed and necessary amendments to STGs can be made. Leveraging the well-established EMR system, a real-time audit-feedback mechanism can be instituted to improve compliance with STGs.

Changes in Serum CRP and PCT Levels in Patients with Acute Simple Lower Urinary Tract Infection and Evaluation of the Efficacy of Treatment with Shuangdong Capsules

Objective

The aim of this study is to investigate the changes and significance of serum C-reactive protein (CRP) and procalcitonin (PCT) levels in patients with acute simple lower urinary tract infection (ALUTI) and to analyze the efficacy of treatment with Shuangdong capsules, so as to provide a basis for the rational clinical application of drugs.

Methods

92 patients with ALUTI (observation group) were randomly divided into 46 cases each in group A and group B. Group A was treated with basic anti-infective drugs, while group B was treated with Shuangdong capsules, and the duration of treatment in both groups was 14 days. The curative effect of the two groups was analyzed, and the changes in serum PCT and CRP levels were compared before and after treatment and compared with 40 healthy people in the control group.

Results

The serum PCT and CRP levels, the number of urinary leukocyte count (LEU), and the number of urinary bacterial count (BACT) were significantly higher in Group A and Group B than in the healthy control group before treatment (P < 0.05). After treatment, the total clinical efficiency of patients in group B (97.83%) was significantly higher than that in group A (78.26%) (P < 0.05). The serum PCT and CRP levels, the number of urinary LEU, and the number of urinary BACT decreased in both groups after treatment compared with those before treatment, and all of them were significantly lower in group B than in group A (P < 0.05). The area under the curve (AUC) values of serum PCT and CRP levels for the diagnosis of acute simple lower urinary tract infection were 0.747 (95% CI 0.633-0.860) and 0.926 (95% CI 0.870∼0.982), both with high sensitivity and specificity.

Conclusion

The Shuangdong capsule combined with conventional antibacterial drugs has better clinical efficacy in the treatment of acute simple lower urinary tract infection; serum CRP and PCT levels in patients with acute simple lower urinary tract infection can be used as indicators for diagnosis and efficacy determination of the infection.

Patterns and trends of antibacterial treatment in patients with urinary tract infections, 2015–2019: an analysis of health insurance data

Background

Urinary tract infections are among the most common reason for encounter and subsequent antibiotic prescriptions. Due to the risk of collateral damage and increasing resistance rates, explicit recommendations against the use of fluoroquinolones like ciprofloxacin in uncomplicated urinary tract infections have been issued. However, to what extent these recommendations were followed and if there are relevant differences between the disciplines involved (general practitioners, urologists, paediatricians and gynaecologists) are unknown.

Methods

We used anonymized data from a local statutory health insurance (SHI) company, which covered about 38% of all SHI-insured persons in the federal state of Bremen, Germany between 2015—2019. Data included demographics, outpatient diagnoses and filled prescriptions on an individual level.

Results

One-year prevalence of urinary tract infections was 5.8% in 2015 (females: 9.2%, males: 2.5%). Of all 102,715 UTI cases, 78.6% referred to females and 21.4% to males, 6.0% of cases were younger than 18 years. In females, general practitioners were the most common diagnosing speciality (52.2%), followed by urologists (20.0%) and gynaecologists (16.1%). Overall, fluoroquinolones were most often prescribed (26.3%), followed by fosfomycin (16.1%) and the combination of sulfamethoxazole and trimethoprim (14.2%). Fluoroquinolones were most often prescribed by urologists and general practitioners, while gynaecologists preferred fosfomycin. During the study period, shares of fluoroquinolones decreased from 29.4% to 8.7% in females and from 45.9% to 22.3% in males.

Conclusions

Despite a clear trend toward a more guideline adherent prescription pattern, there is still room for improvement regarding the use of second-line antibiotics especially fluoroquinolones. The choice of antibiotics prescribed differs between specialities with higher uptake of guideline-recommended antibiotics by gynaecologists, mainly because of higher prescription shares of fosfomycin.
