RESUMO

Asymptomatic bacteriuria is frequently encountered in clinical practice and should be treated only in pregnant women and before invasive urological procedures. Inappropriate treatment of asymptomatic bacteriuria is associated with numerous adverse effects including allergic reactions, increased antibiotics resistance and increase risk of Clostridioides difficile infection. Positive urinary culture often leads to antimicrobial treatment, irrespective of urinary symptoms. Therefore, urine analysis and culture should be performed only in symptomatic individuals or in asymptomatic individuals with a clear indication for treatment.

RESUMO

To evaluate the safety and efficacy of tubeless percutaneous nephrolithotomy (PCNL) in patients with Escherichia coli (E. coli) bacteriuria. We conducted a retrospective review of 84 patients with E. coli bacteriuria who underwent PCNL. Patients were divided into two groups according to whether a nephrostomy tube is placed at the end of the procedure. Preoperative clinical data, surgical outcomes, and postoperative complications were compared. Then, regression analysis of factors predicting success rate of PCNL in patients with E. coli bacteriuria was performed. After PCNL, residual fragments ≤ 4 mm were considered as success. At baseline, the two groups were similar with regard to age, gender, BMI, underlying disease, hydronephrosis, stone characteristics, and urinalysis. Postoperative fever occurred in 1 patient (3.8%) in the tubeless PCNL group, and in 5 patients (8.6%) in the conventional PCNL group (p > 0.05). There were no significant differences in terms of successful rate, decrease in hemoglobin, pain scores, blood transfusion, and hospitalization expenses. However, the tubeless PCNL group had significantly shorter operative time (60 vs. 70 min, p = 0.033), indwelling time of catheter (2 vs. 4 days, p < 0.001), and hospital stays (3 vs. 5 days, p < 0.001) than the conventional PCNL group. In the analysis of factors predicting success, the stone diameter, stone burden, and operative time were associated with success rate of PCNL. It is safe and effective to perform tubeless PCNL in patients with E. coli bacteriuria. Compared to conventional PCNL, tubeless PCNL accelerates patient recovery and shortens hospital stays.

RESUMO

INTRODUCTION: Urinary tract infection (UTI) is a common bacterial complication in pregnancy. The study aimed to estimate the prevalence, risk factors, and bacterial etiology of UTI during pregnancy and determine the efficacy of antimicrobial drugs in treating UTIs. METHODOLOGY: Urine specimens and clinical data were collected from pregnant women who attended primary health centers in Erbil, Iraq. All specimens were cultured on appropriate media and identified by standard microbiological methods. The pregnant women were grouped into symptomatic UTI group, asymptomatic bacteriuria group, and the control group. The agar dilution method was used to determine antimicrobial susceptibility. RESULTS: Among the 5,042 pregnant women included in this study, significant bacteriuria was found in 625 (12.40%) of the cases, and 198 (31.68%) had symptomatic UTI, of which 43.59% were diagnosed during the third trimester. Out of the 643 bacteria isolated, 33.28% were symptomatic UTI, of which 43.59% developed during the third trimester. There was a significant difference in the bacterial etiology between symptomatic UTI and asymptomatic bacteriuria (p = 0.002), as well as between cystitis and pyelonephritis (p = 0.017). The most common bacterial species isolated was Escherichia coli, which was susceptible to fosfomycin (100%), meropenem (99.45%), and nitrofurantoin (97.8%). CONCLUSIONS: Pregnant women are more likely to develop UTI in the third trimester. Escherichia coli is the predominant pathogen. The study suggests the use of fosfomycin, meropenem, and nitrofurantoin for the treatment of UTI. No Gram-positive isolates were resistant to daptomycin.

RESUMO

BACKGROUND: Purulent pericarditis (PP)- a purulent infection involving the pericardial space-requires a high index of suspicion for diagnosis as it often lacks characteristic signs of pericarditis and carries a mortality rate as high as 40% even with treatment. Common risk factors include immunosuppression, diabetes mellitus, thoracic surgery, malignancy, and uremia. Most reported cases of PP occur in individuals with predisposing risk factors, such as immunosuppression, and result from more commonly observed preceding infections, such as pneumonia, osteomyelitis, and meningitis. We report a case of PP due to asymptomatic bacteriuria in a previously immunocompetent individual on a short course of high-dose steroids. CASE PRESENTATION: An 81-year-old male presented for severe epigastric pain that worsened with inspiration. He had been on high-dose prednisone for presumed inflammatory hip pain. History was notable for urinary retention requiring intermittent self-catheterization and asymptomatic bacteriuria and urinary tract infections due to methicillin-sensitive Staphylococcus aureus (MSSA). During the index admission he was found to have a moderate pericardial effusion. Pericardial fluid cultures grew MSSA that had an identical antibiogram to that of the urine cultures. A diagnosis of purulent pericarditis was made. CONCLUSION: PP requires a high index of suspicion, especially in hosts with atypical risk factors. This is the second case of PP occurring as a result of asymptomatic MSSA bacteriuria. Through reporting this case we hope to highlight the importance of early recognition of PP and the clinical implications of asymptomatic MSSA bacteriuria in the setting of urinary instrumentation and steroid use.

RESUMO

INTRODUCTION: In the era of increased bacterial resistance, the main strategy is to reduce the prescription of antibiotics when possible. Nowadays, it is highly recommended to screen for asymptomatic bacteriuria (ABU), prior to urological surgery with potential mucosal breach or urine exposure. Screening and treating urinary colonization is a strategy widely adopted before radical and partial nephrectomy but without any evidence. Our main end point in this study is to analyze the relationship between preoperative urine culture and the risk of postoperative febrile urinary tract infection (UTI) or surgical-site infection (SSI) in partial or radical nephrectomy patients. METHODS: We conducted a multicenter retrospective cohort study between January 2016 and January 2023 in 11 French tertiary referral hospitals (TOCUS database). We collected the data for 269 patients including several pre-, intra-, and post-operative variables that could potentially increase the risk of postoperative UTI and SSI including preoperative urinary culture results. RESULTS: The incidence rate of postoperative UTI and SSI was 8.9% in our study. After conducting a logistic multivariate analysis, a propensity score matching analysis, and a subgroup analysis, we found no significant correlation between the urine culture and the postoperative UTI risk [OR = 1.2 (0.5-2.7) (p = 0.7)]. Only the postoperative non-infectious complications were related to a higher risk of postoperative UTI [OR = 12 (4-37), p < 0.001)]. CONCLUSION: Our research shows that screening and treating for ABU prior to radical or partial nephrectomy seems to be unnecessary to prevent postoperative UTI and SSI.

RESUMO

PURPOSE: Patients with ureteric stents have symptoms that overlap with infection symptoms. Thus, clinicians unnecessarily give antibiotics to stented patients with bacteriuria despite guidelines. In stented patients, little is known about risk factors for developing bacteriuria or urosepsis. The objectives were to identify the frequency and risk factors for developing bacteriuria and urosepsis in patients with stents. METHODS: In this retrospective cohort study, we reviewed patients with ureteric stents placed or exchanged over 1 year. We examined associations between bacteriuria or urosepsis and host risk factors. Univariable and multivariable logistic analyses were performed. RESULTS: Of 286 patients (mean age: 57.2 years), 167 (58.4%) were male. The main stent indications were stone, stricture, cancer and extrinsic compression. The median stented period was 61 days. The frequency of bacteriuria was 59/286 (21%). ASA status 3 and 4 had 5 times the odds of having bacteriuria relative to ASA status 1. Stent duration > 2 months had 5.5 times the odds relative to ≤ 2 months. Urosepsis was infrequent, 13/286 (4.5%). Five patients had bacteraemia. A stent duration over 2 months had nearly 6 times the odds of urosepsis. CONCLUSION: ASA status higher than 2 and stent time greater than 2 months raise the odds of developing bacteriuria. A stent duration longer than 2 months was the only predictor of urosepsis. Though 21% of patients had bacteriuria, 4.5% had urosepsis. Hence, bacteriuria without sepsis should not be treated with antibiotics, thus aiding antimicrobial stewardship.

RESUMO

OBJECTIVES: We aimed to identify the prevalence, bacterial isolates, antimicrobial susceptibility profile, and factors associated with asymptomatic bacteriuria (ASB) in patients with type 2 diabetes mellitus (T2DM) in rural southwestern Nigeria. METHODS: We performed a hospital-based cross-sectional study of patients with T2DM and ASB. Demographic and clinical data were collected using questionnaires. Urine samples were cultured using standard laboratory procedures, and bacterial colonies were isolated and antimicrobial sensitivity was performed using the disc diffusion technique. Relationships between variables were assessed using adjusted odds ratios (AORs) and 95% confidence intervals (CIs). RESULTS: Of the 280 participants, 73 (26.1%) had ASB (95% CI: 20.9%-31.2%). The most commonly identified isolate was E. coli (45/73; 61.7%), 100.0% of which were sensitive to cefuroxime but resistant to ciprofloxacin. Female sex (AOR, 6.132; 95% CI: 2.327-16.157), living below the poverty line (AOR, 2.066; 95% CI: 1.059-4.029), uncontrolled blood glucose (AOR, 2.097; 95% CI: 1.000-4.404), and a history of indwelling urethral catheterization (AOR, 14.521; 95% CI: 4.914-42.908) were associated with ASB. CONCLUSION: The findings suggest that cefuroxime should be used as an empirical treatment, pending urine culture and sensitivity, and that efforts should be made to prevent ASB in rural southwestern Nigeria.

RESUMO

Children with a neurogenic bladder are at risk of developing recurrent urinary tract infections and long-term kidney failure. Due to an altered lower urinary tract, children may be overtreated for simple bacteriuria or undertreated for a potentially severe urinary tract infection. This group of patients represent high users of healthcare, and are at risk of colonization and development of antibiotic resistance. Bladder washouts with non-antibiotic electrochemically activated solutions are a potential new prophylactic option for patients with bladder dysfunction when clean intermittent catheterization has resulted in chronic bacteriuria.

RESUMO

BACKGROUND: Bacteriuria is common among kidney transplant recipients (KTR). Risk factors and outcomes associated with bloodstream infection due to a urinary source (BSIU) in KTR are poorly understood. METHODS: This single center case-control study from 2010 to 2022 compared KTR with BSIU to those with bacteria without bloodstream infection (BU). Multivariable logistic regression identified BSIU risk factors, and Cox models assessed its impact on graft failure. RESULTS: Among 3435 patients, who underwent kidney transplantation at Emory Hospital, 757 (22%) developed bacteriuria, among whom 142 (18.8%) were BSIU. Male sex, presence of Escherichia coli, Klebsiella pneumoniae, or Pseudomonas species in urine culture, urethral stricture, neuromuscular bladder disorder, and history of diabetes-induced renal failure were independently associated with increased odds of BSIU (Male sex: aOR 2.29, 95% CI 1.52, 3.47, E. coli: aOR 5.14, 95% CI 3.02, 9.13; K. pneumoniae aOR 3.19, 95% CI 1.65, 6.27, Pseudomonas spp aOR 3.06, 95% CI 1.25, 7.18; urethral stricture: 4.10, 95% CI 1.63, 10.3, neuromuscular bladder disorder aOR 1.98, 95% CI 1.09, 3.53, diabetes: aOR 1.64, 95% CI 1.08, 2.49). BSIU was associated with increased hazard of graft failure (HR 1.52, 95% CI 1.05, 2.20). CONCLUSION: Close monitoring is warranted for male KTR with bacteriuria, those with urine cultures positive for Pseudomonas spp, K. pneumoniae, or E. coli, as well as KTR with a history of diabetes-induced renal failure, urethral stricture, or neuromuscular bladder disorder due to their risk for developing BSIU. Future research should explore strategies to mitigate BSIU risk in these high-risk KTR and reduce the associated risk of long-term graft failure.

RESUMO

Importance: Guidelines recommend withholding antibiotics in asymptomatic bacteriuria (ASB), including among patients with altered mental status (AMS) and no systemic signs of infection. However, ASB treatment remains common. Objectives: To determine prevalence and factors associated with bacteremia from a presumed urinary source in inpatients with ASB with or without AMS and estimate antibiotics avoided if a 2% risk of bacteremia were used as a threshold to prompt empiric antibiotic treatment of ASB. Design, Setting, and Participants: This cohort study assessed patients hospitalized to nonintensive care with ASB (no immune compromise or concomitant infections) in 68 Michigan hospitals from July 1, 2017, to June 30, 2022. Data were analyzed from August 2022 to January 2023. Main Outcomes and Measures: The primary outcome was prevalence of bacteremia from a presumed urinary source (ie, positive blood culture with matching organisms within 3 days of urine culture). To determine factors associated with bacteremia, we used multivariable logistic regression models. We estimated each patient's risk of bacteremia and determined what percentage of patients empirically treated with antibiotics had less than 2% estimated risk of bacteremia. Results: Of 11 590 hospitalized patients with ASB (median [IQR] age, 78.2 [67.7-86.6] years; 8595 female patients [74.2%]; 2235 African American or Black patients [19.3%], 184 Hispanic patients [1.6%], and 8897 White patients [76.8%]), 8364 (72.2%) received antimicrobial treatment for UTI, and 161 (1.4%) had bacteremia from a presumed urinary source. Only 17 of 2126 patients with AMS but no systemic signs of infection (0.7%) developed bacteremia. On multivariable analysis, male sex (adjusted odds ratio [aOR], 1.45; 95% CI, 1.02-2.05), hypotension (aOR, 1.86; 95% CI, 1.18-2.93), 2 or more systemic inflammatory response criteria (aOR, 1.72; 95% CI, 1.21-2.46), urinary retention (aOR, 1.87; 95% CI, 1.18-2.96), fatigue (aOR, 1.53; 95% CI, 1.08-2.17), log of serum leukocytosis (aOR, 3.38; 95% CI, 2.48-4.61), and pyuria (aOR, 3.31; 95% CI, 2.10-5.21) were associated with bacteremia. No single factor was associated with more than 2% risk of bacteremia. If 2% or higher risk of bacteremia were used as a cutoff for empiric antibiotics, antibiotic exposure would have been avoided in 78.4% (6323 of 8064) of empirically treated patients with low risk of bacteremia. Conclusions and Relevance: In patients with ASB, bacteremia from a presumed urinary source was rare, occurring in less than 1% of patients with AMS. A personalized, risk-based approach to empiric therapy could decrease unnecessary ASB treatment.

RESUMO

INTRODUCTION AND HYPOTHESIS: Best practices suggest nontreatment for asymptomatic bacteriuria in a nonpregnant population, yet there is little literature on patient preference or understanding of asymptomatic bacteriuria treatment. We hypothesize that there might be core factors that affect antibiotic preferences and care-seeking decisions for urinary tract infection and asymptomatic bacteriuria in a postmenopausal population. METHODS: We performed semi-structured interviews with postmenopausal individuals who had been previously treated for at least one patient-reported urinary tract infection. Interviews covered a discussion about their approach to seeking antibiotics for management and knowledge/preferences for asymptomatic bacteriuria management. Two authors independently coded the interviews and identified a set of symptom-related knowledge and experiences that relate to care-seeking and treatment preferences. We then graphically represented a mental model of antibiotic-seeking practices as an influence diagram, illustrating how knowledge and values affect preferences for care. RESULTS: We performed 30 interviews of participants with a mean age of 69.4 (SD 6.4). Among participants, there were four core factors that influence antibiotic seeking for bacteriuria. Participants noted concern for sequelae from untreated bacteria as their primary motivation, but also noted past experiences, information sources, and testing results as themes that affected their mental model surrounding bacteriuria treatment. CONCLUSIONS: The cognitive approach to care-seeking and treatment preference for bacteriuria is influenced by a few central factors. An improved ability to allay concerns either by provider discussions or educational materials are necessary to bridge the gap from the existence of evidence-based guidelines to patient and provider comfort with adherence to these guidelines.

RESUMO

PURPOSE: Patients with suspected UTIs are categorized into 3 clinical phenotypes based on current guidelines: no UTI, asymptomatic bacteriuria (ASB), or UTI. However, all patients may not fit neatly into these groups. Our objective was to characterize clinical presentations of patients who receive urine tests using the "continuum of UTI" approach. MATERIALS AND METHODS: This was a retrospective cohort study of a random sample of adult noncatheterized inpatient and emergency department encounters with paired urinalysis and urine cultures from 5 hospitals in 3 states between January 01, 2017, and December 31, 2019. Trained abstractors collected clinical (eg, symptom) and demographic data. A focus group discussion with multidisciplinary experts was conducted to define the continuum of UTI, a 5-level classification scheme that includes 2 new categories: lower urinary tract symptoms/other urologic symptoms and bacteriuria of unclear significance. The newly defined continuum of UTI categories were compared to the current UTI classification scheme. RESULTS: Of 220,531 encounters, 3392 randomly selected encounters were reviewed. Based on the current classification scheme, 32.1% (n = 704) had ASB and 53% (n = 1614) did not have a UTI. When applying the continuum of UTI categories, 68% of patients (n = 478) with ASB were reclassified as bacteriuria of unclear significance and 29% of patients (n = 467) with "no UTI" were reclassified to lower urinary tract symptoms/other urologic symptoms. CONCLUSIONS: Our data suggest the need to reframe our conceptual model of UTI vs ASB to reflect the full spectrum of clinical presentations, acknowledge the diagnostic uncertainty faced by frontline clinicians, and promote a nuanced approach to diagnosis and management of UTIs.

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

A retrospective case-control study was performed to determine the clinical differences between dogs with enterococcal bacteriuria (n = 96 cases) and control dogs with any other bacteriuria (n = 288). More dogs with nonenterococcal bacteriuria demonstrated lower urinary tract clinical signs such as hematuria, pollakiuria, and stranguria (40% versus 27%, P = .02). Recessed vulva (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.4-4.2, P < .001), hyperadrenocorticism (OR 0.149, 95% CI 0.004-0.066, P = .03), chronic kidney disease (OR 2.29, 95% CI 1.14-4.51, P = .01), and myelopathy (OR 5.77, 95% CI 3.07-10.82, P < .001) were more common in dogs with enterococcal bacteriuria. Enterococcus spp. cases were more likely to have polymicrobial growth than controls (OR 28.52; 95% CI 12.63-69.62, P ≤ .001). Pugs (OR 7.4, 95% CI 2.6-19.9, P < .001), bearded collies (OR 24.3, 95% CI 2.9-205.5, P = .003), and Saint Bernards (OR 17.3, CI 1.9-154.4, P = .01) had increased odds of enterococcal growth compared with mixed-breed dogs. In the control (but not the case) population, there was an association between resolution of clinical signs and administration of antimicrobials (P = .01). The signalment, clinical signs, comorbidities, and response to therapy in dogs with enterococcal bacteriuria are different from dogs with other bacteriuria.

RESUMO

Treatment of asymptomatic bacteriuria (ASB) is a common, but often unnecessary, practice. Our objective was to determine the impact of restrictive urinalysis reflex to culture (UARC) criteria on rate of urine cultures (UC) ordered and ASB treatment. Criteria were modified from positive leukocyte esterase, positive nitrites, or white blood cells (WBC) >10 cells to only WBC >10 cells. This pre-post study evaluated UARCs ordered in the emergency department or inpatient units. The primary outcome was the proportion of reflex UCs prevented. Secondary outcomes included the frequency of repeat UARCs and stand-alone UCs, gram-negative rod (GNR) bacteremia, and ASB treatment. In the pre-intervention, there were 4761 UARCs compared to 5420 in the post-intervention; 37.9 % and 21.4 % reflexed to UCs, a 43.5 % reduction in UCs. The rate of repeat UARCs, stand-alone UCs, and GNR bacteremia in the pre- and post-interventions were similar. ASB treatment rate was numerically lower in the post-intervention.

RESUMO

OBJECTIVE: To determine which bacteria are associated with an increased risk of 90-day complications after urethroplasty. Preoperative bacteriuria is associated with an increased risk of complications after urethroplasty. However, it remains unclear which specific micro-organisms are the primary drivers of this morbidity. METHODS: A single-institution, 2-surgeon retrospective review was performed on patients undergoing urethroplasty from 08/2003 to 06/2021. Preoperative bacteriuria was considered significant when the patient had a mixed culture with ≥108 CFU/L or an identifiable micro-organism with ≥106 CFU/L. Descriptive statistics were used to summarize the results and chi-square was used to determine the association between 90-day complications (Clavien ≥2) and clinical characteristics/bacteria. RESULTS: Out of 1611 patients, 23.2% (373) had significant preoperative bacteriuria. The most common pathogens included coagulase-negative staphylococcus 18.5% (69), mixed growth 15.8% (59), Escherichia coli 10.7% (40), and Enterococcus 14.2% (53). 7.9% (128/1611) experienced a significant 90-day complication (Clavien-Dindo ≥2). Gram-negative bacilli including E coli, Pseudomonas sp, Klebsiella sp, Serratia sp, Citrobacter sp, Achromobacter sp, Stenotrophomonas sp, and Morganella sp were associated with higher rates of postoperative complications (14.2%; P = .01) as well as Enterococcus sp (15.1%; P = .03). However, gram-positive cocci (7.9%; P = .97), gram-positive bacilli (11.8%; P = .47), mixed growth (5.1%; P = .54) and Candida (16.7%; P = .27) were not. Neither escalating concentrations of bacteria (P = .44) or number of strains (P = .08) were associated with increased risk of complications. CONCLUSION: The main driver of bacteriuria-related complications after urethroplasty are gram-negative bacilli and Enterococcus sp. Patients with bacteriuria related to other micro-organisms can likely proceed with urethroplasty without increased risk of postoperative complications.

RESUMO

This case presents the clinical and genomic aspects of a rare and multidrug-resistant Pseudomonas guariconensis isolate carrying blaVIM-2 and highlights the need for heightened awareness in healthcare facilities. A 63-year-old woman underwent surgery for the diagnosis of a paraspinal abscess and infectious spondylitis. During hospitalization, the patient was diagnosed with heart failure exacerbation. The patient had no symptoms of urinary tract infection and met the criteria for asymptomatic bacteriuria. In urine culture, colonies of the organism grew >105 CFU/mL on blood agar and on MacConkey agar. The Bruker Biotyper mass spectrometry showed P. guariconensis. Based on the 16S rRNA gene sequence showed that a 99.79 % match with as P. guariconensis LMG 27394T. The average nucleotide identity with P. guariconensis LMG 27394T was 91.53 %. Antimicrobial susceptibility testing showed that the isolate was not susceptible to most of the antibiotics. Antimicrobial resistance genes identified were aph(6)-Id, aph(3″)-Ib, aac(6')-Ib3, aac(3)-If, gyrA mutation (T83I) and blaVIM-2.
