BACKGROUND: Recurrent bacterial cystitis, often referred to as recurrent urinary tract infection (UTI), can be difficult to manage and alternative treatments are needed. HYPOTHESIS/OBJECTIVE: Intravesicular administration of asymptomatic bacteriuria (ASB) E. coli 212 will not be inferior to antimicrobial treatment for the management of recurrent UTI in dogs. ANIMALS: Thirty-four dogs with >1 UTI in the 12 months before presentation. METHODS: All dogs were deemed normal otherwise based on absence of abnormalities on physical examination, CBC, serum biochemical panel, and abdominal ultrasonography. Dogs were randomized to 1 of 2 treatment groups: Group 1 antimicrobials for 7 days or group 2 intravesicular administration of ASB E. coli 212. Owners were provided a voiding questionnaire regarding their dogs clinical signs, which was completed daily for 14 days to assess clinical cure. Dogs were examined on days 7 and 14 to assess clinical cure, and urine specimens were submitted for urinalysis and bacterial culture. RESULTS: Clinical cure rates for ASB E. coli 212-treated dogs were not inferior to 7 days of antimicrobial treatment with a 12% margin of difference to determine non-inferiority. No significant difference was found between the treatment groups on days 7 and 14 in the proportion of dogs achieving ≥50% or ≥75% reduction in their clinical score compared with baseline. CONCLUSIONS AND CLINICAL IMPORTANCE: These data suggest that intravesicular administration of ASB E. coli 212 is not inferior to antimicrobials for the treatment of recurrent UTI in dogs. This biotherapeutic agent could help alleviate the need for antimicrobials for some dogs with recurrent UTI, improving antimicrobial stewardship.

Type 2 diabetes mellitus (T2DM) patients are at increased risk of infections, such as malignant otitis externa and rhinocerebral mucormycosis, with the urinary tract being the most affected (for example, emphysematous pyelonephritis commonly caused by Escherichia coli). Hence, this study assessed the prevalence of bacteriuria and antibiogram patterns of bacteria isolates among T2DM patients visiting the Ejisu Government Hospital in the Ashanti Region, Ghana. In this cross‐sectional study, 58 patients visiting the hospital for routine healthcare were conveniently recruited after obtaining informed consent. Data on sociodemographic characteristics and medical history were obtained using pretested structured questionnaires. Mid‐stream urine was collected for bacteria isolation and identification using standard bacterial culture and biochemical tests. Bacteria cultures ≥ 105 CFU/mL were considered significant bacteriuria. The antibiotic sensitivity patterns of the bacteria isolates were evaluated using the Kirby‐Bauer disc diffusion method. Bacteriuria was recorded among 15.5% (9/58) of the patients, mainly those with no previous history (77.8%) and no symptoms (55.6%) of urinary tract infections (UTIs). E. coli (55.6%) and Klebsiella spp. (44.6%) were primarily isolated from the T2DM patients. All the bacteria isolates (E. coli and Klebsiella spp.) demonstrated the highest resistance to co‐trimoxazole and tetracycline (55.6%) and a complete susceptibility to amikacin and levofloxacin (100%). However, 60% of the E. coli isolates and 25% of the Klebsiella isolates were multidrug resistant (MDR; resistant to at least one antibiotic agent in three or more antimicrobial categories). The study shows that T2DM patients have bacteria in their urine which are resistant to most common antibiotics, even among those with no history of UTIs; hence, routine bacterial culture and antibiotic sensitivity testing among T2DM patients is recommended for better patient management to reduce the co‐morbidities of UTIs.

The current study was conducted the relationship between circumcision and urinary tract infection in children under five years. in total, 100 child were included from various hospitals in the city of samarraa, which included (Samarra General Hospital and alkhairi Hospital), for the period between 9/1/2022 and 4/15 /2023 The current study aimed to isolate Escherichia coli bacteria that cause urinary tract infections in children less than five years old and evaluate some risk factors. 100 samples were isolated from children suffering from urinary tract infections of both genders from various hospitals in the city of Samarra, for the period between 9/1/2022 and 4/15. /2023. The results of microscopic examination showed that 55% of the samples were accompanied by bacteriuria and pyuria, 12% with bacteriuria, 22% with pyuria, and 11% without both. Bacterial culture results showed that 67% of the samples showed bacterial growth, and 64.1% of the specimen were diagnosed as Escherichia coli and the rest of the percentage was distributed among other bacterial species. The results showed that all male samples that showed bacterial growth were from uncircumcised children. The isolates showed resistance to many antibiotics. and the blood test for males and females showed a decrease in the level of ferritin and a decrease in some blood parameters compared with the normal levels, especially hemoglobin.

Purpose: The purpose of this study was to evaluate risk factors associated with positive urine cultures following holmium laser enucleation of the prostate (HoLEP). Materials and Methods: The data from a prospectively maintained database were analyzed to evaluate urine culture results following HoLEP and determine the contribution of predefined variables (age, prostate size, Charlson comorbidity score, surgical time [surrogate for case difficulty], the presence of a catheter preoperatively, postoperative urinary retention, and preoperative positive culture) on urine culture positivity at 60 days postoperatively. Statistical analyses included logistic regression and ANOVA. Results: The data from 136 subjects were included in the database and were evaluated at a median of 13.37 ± 6.72 months after their HoLEP. Postoperative positive cultures were noted in 23 subjects (16.91%). Preoperative positive cultures were found to predict positive postoperative urine cultures (odds ratio: 3.78, confidence interval: 1.18–12.78, P = 0.03). However, the preoperative and postoperative results were discordant in 9 of 14 subjects with both positive preoperative and postoperative cultures. Conclusions: Positive preoperative cultures were predictive of positive postoperative cultures. However, the pre- and postoperative results were often discordant. Host factors increasing susceptibility to bacteriuria may explain these findings.

Abstract This study explores the role of the vaginal microbiota (VM) in the pathophysiology of asymptomatic bacteriuria (ASB) in a cohort of 1,553 pregnant women. Worldwide, E. coli remains the most common etiological agent of bacteriuria during pregnancy and also a major causative agent of newborn infections. A healthy VM is typically characterized by low diversity and is dominated by lactic acid-producing species, notably those from the Lactobacillus genus. Our results point to decreases in Lactobacillus spp associated with an increase of gut-microbiota-associated species from the Enterobacterales order. Escherichia coli exhibited the most pronounced increase in abundance within the VM during bacteriuria and was notably associated with ASB. Molecular typing and antimicrobial resistance characterization of 72 metagenome assembled E. coli genomes (MAGs) from these pregnant women revealed a genomic signature of extraintestinal pathogenic E. coli (“ExPEC”) strains, which are involved in various extraintestinal infections such as urinary tract infections, newborn infections and bacteremia. Microbial diversity within the vaginal samples from which an E. coli MAG was obtained showed a substantial variation, primarily marked by a decrease in abundance of Lactobacillus species. Overall, our study shows how disruption in key bacterial group within the VM can disrupt its stability, potentially leading to the colonization by opportunistic pathogens.

Abstract Background Asymptomatic bacteriuria (ASB) – the presence of bacteria in urine without urinary tract infection (UTI) related signs & symptoms (S&S) – is common in the elderly bladder and is not considered pathogenic for UTI. We hypothesise that colonisation with non-uropathogenic bacteria could protect the bladder from invasion of more harmful bacteria. The exact role and dynamics of bacteriuria in the relation to the development of a UTI is still unknown. We aim to provide insight into the course of bacteriuria in the elderly bladder and its relation to UTI in frail older adults. Methods and analysis A prospective observational cohort study is being conducted in Dutch nursing homes (NHs) between February 2024 and December 2025. Urine samples and case report forms (CRF) on UTI-related S&S will be collected from each consenting NH resident every 3 months for a follow-up period of 18 months. Whenever a UTI-suspicion occurs in between the 3 monthly time points, additional data and a urine sample will be collected. Urine samples undergo several urinalyses (e.g. dipstick and bacterial culture). Additional molecular analysis will be conducted on a selection of cultured Escherichia coli (E. coli) for virulence genes. Primary analyses will be conducted between residents with and without ASB at each time point. The primary outcome is UTI incidence during follow-up. In secondary analyses we will also take into account the low versus high presence of virulence genes of the E. coli. Discussion The combination of high ASB prevalence and a reduced ability of frail older adults to express UTI-related S&S may lead to UTI misdiagnosis and inappropriate antibiotic use. To our knowledge, this is the first study to investigate the dynamics and role of bacteriuria in the elderly bladder and their potential protective effect on the development of UTI. The study findings with comprehensive analysis of epidemiological, clinical and molecular data could set the fundamental base for future guidelines and studies, and contribute to improving prevention, diagnosis and treatment of UTI in frail older adults, in addition to contributing to antibiotic stewardship in NHs.

Objective: This study aimed at determining the significance of pyuria as a screening test for UTI in children with sickle cell anaemia (SCA). Methods: Two hundred and seventy-two children with SCA, aged 6 months to 15 years, were studied out of which 185 (68.0%) were in stable state and 87 (32.0%) were in crises. Their urine was assessed for microscopy culture and sensitivity. Significant pyuria and bacteriuria was determined using standard methods. Results: Significant bacteriuria was detected in 22 (8.1%) of the 272 subjects with SCA. The prevalence of significant bacteriuria was higher among those in crisis (18/87; 20.7%) than in those in steady state (4/185; 2.2%) and the difference was statistically significant (χ2 = 27.323, p = 0.001). Of the 22 SCA subjects with confirmed UTI, 19 (86.4%) had significant pyuria with a sensitivity of 6.4%, specificity of 68.8%, and positive predictive value of 19.6%. The most common bacterial isolates were Escherichia coli 11 (50.0%) while the least isolated were Salmonella typhi 1 (4.6%). Conclusion: This study indicates that pyuria as a screening test for UTI is not very specific but very sensitive necessitating a more test to be done for diagnosis of UTI.

Abstract Background Neurogenic bladder dysfunction is a major problem for spinal cord injury (SCI) patients not only due to the risk of serious complications but also because of the impact on quality of life. The main aim of this study is to compare the rate of urinary tract infection (UTI) associated with hydrophilic-coated catheters versus uncoated polyvinyl chloride (PVC) catheters among SCI patients presenting with functional neurogenic bladder sphincter disorders. Methodology This was a retrospective cohort study from 2005 to 2020 including adult male or female patients who have an SCI at least more than 1 month ago with neurogenic bladder dysfunction and were using intermittent catheterization (single-use hydrophilic-coated or the standard-of-care polyvinyl chloride uncoated standard catheters) at least 3 times a day to maintain bladder emptying. Results A total of 1000 patients were selected and recruited through a stratified random sampling technique with 467 (47.60%) patients in the uncoated catheter arm and 524 (52.60%) in the coated catheter groups. The three outcome measures, namely: symptomatic UTI, Bacteriuria, and pyuria were significantly higher in the group using uncoated polyvinyl chloride (PVC) catheters compared to hydrophilic-coated catheters at the rate of 79.60% vs.46.60%, 81.10% vs. 64.69, and 53.57% versus 41.79% respectively. Males, elder patients, longer duration, and severity of SCI were associated with increased risk of symptomatic UTI. Conclusions The results indicate a beneficial effect regarding clinical UTI when using hydrophilic-coated catheters in terms of fewer cases of symptomatic UTI. Bacteriuria is inevitable in patients with long-term catheterization, however, treatment should not be started unless the clinical symptoms exist. More attention should be given to the high-risk group for symptomatic UTIs.

Urinary tract infection (UTI) is considered as one of the highly prevalent infections worldwide. Regarding its prevalence, UTI is more common in women. The outcome of the research is expected to predict the severity of the urinary tract infection. The study of prevalence and antibiotic susceptibility helps to provide data on the occurrence of uropathogens in different age groups and helps to treat the infection with effective antibiotics to prevent further progression of infection. The study has been carried out to identify and investigate the prevalence of uropathogens and to determine their antibiotic susceptibility potential. Overall, 713 urine samples were collected, MacConkey agar, Blood agar, CLED agar and Luria-Bertani agar were used for isolation of uropathogens by calibrated loop streak method and incubated at 37°C. Antibiotic susceptibility was carried out using the Kirby Disc diffusion method. A total of 665 showed positive bacteriuria. E. coli (37.3%) and K. pneumoniae (32.03%) were the most common uropathogens followed by E. fergusonii (17.9%), P. aeruginosa (8.4%), and A. baumannii (4.4%). The study found that above 70% of antibiotic susceptibility was observed in fluoroquinolones followed by imipenem, while all isolates showed high resistance to ampicillin. The organisms E. coli, E. fergusonii, and P. aeruginosa exhibited the least susceptibility (>50%) for third-generation cephalosporins. P. aeruginosa and A. baumannii showed no susceptibility to nitrofurantoin, whereas other isolates were least susceptible. The study concludes that K. pneumoniae and E. coli were highly prevalent within the study group and that fluoroquinolone and imipenem can be effective for treatment.

Background: Despite the prevalence of echogenic foci floating in the urinary bladder seen in ultrasonography in dogs, surprisingly little has been written on its significance, including its potential association with urinalysis. The objective of the study was to determine the diagnostic value of the echogenic foci floating in urinary bladders in dogs. Results: - Cystosonography was performed on 45 dogs. Bladder contents were examined and divided into positive (containing echogenic particles) and negative (absent echogenic particles) groups according to the presence and absence of floating echogenic particles. Five mL of urine was collected via cystocentesis. Urine analysis and culture were done and the relationship between ultrasound evaluation and urinalysis results was investigated. In dogs with bladder echogenic particles in ultrasonography, the prevalence of hematuria, pyuria, bacteriuria, and lipiduria were 88.9%, 92.6%, 29.6%, and 70.3%, respectively. However, in dogs in which echogenic particles were not observed in their bladders, the prevalence of hematuria, pyuria, bacteriuria, and lipiduria was 77%, 50%, 5.5%, and 77%, respectively. There was a significant association between bladder debris and positive urine culture, with an odds ratio of 7.15 (95% confidence interval: 0.81–63.28) compared with matched controls. Furthermore, there was a significant relationship between the presence of floating echogenic particles with pyuria, and urine color (p ≤ 0.05). Conclusion: In conclusion, the present results showed the detection of bladder debris on ultrasound can be a predictor for pyuria and positive urine culture in dogs. [ABSTRACT FROM AUTHOR]

The relationship between bacteriuria and subsequent symptomatic infections, particularly bacteraemia, has been a subject of ongoing research. We aim to investigate the clinical characteristics, long-term outcomes, and factors associated with subsequent symptomatic infection following an initial multidrug-resistant P. aeruginosa (MDRP) bacteriuria episode. A retrospective cohort study was conducted among patients with MDRP bacteriuria who were hospitalized at a tertiary care hospital from 2009 to 2018, with a 12-month follow-up period for each patient. The primary endpoint was the incidence of subsequent symptomatic MDRP infections at any site, and the secondary endpoint was the overall mortality rate. A total of 260 patients with MDRP bacteriuria were included in the analysis, of whom 155 patients (59.6%) had asymptomatic bacteriuria. Subsequent symptomatic MDRP infections were documented in 79 patients (30.3%) within 12 months of the initial bacteriuria episode: UTI (n = 47, 18.1%), pneumonia (n = 21, 8.1%), bacteraemia (n = 9, 3.5%), soft tissue infection (n = 7, 2.7%), and bone and joint infection (n = 4, 1.5%). Intensive care unit (ICU) acquisition and recurrent bacteriuria were independent risk factors of subsequent symptomatic infections in patients with MDRP bacteriuria. The overall mortality rate was 16.9%, with 31.8% of deaths estimated to be associated with MDRP infection. Solid tumours, cardiovascular diseases, chronic liver disease, chronic lung disease, ICU acquisition, absence of pyuria, and concurrent MDRP bacteraemia were independent predictors of mortality. MDRP bacteriuria has the potential for progression to symptomatic infection and associated mortality. Targeted interventions and prevention strategies were crucial to reduce subsequent infections in patients with MDRP bacteriuria, especially in high-risk patients. [ABSTRACT FROM AUTHOR]

Objective: Unusual clinical course Background: Sodium-glucose co-transporter 2 inhibitors (SGLT2), such as empagliflozin, used to treat type 2 diabetes mellitus (DM), can increase the risk of infections, including urinary tract infections and osteomyelitis, especially in elderly patients. The use of SGLT2 inhibitors has been increasing dramatically in the last few years. Therefore, their adverse effects and complications have also been increasing. Herein, this report describes a 73-year-old man with type 2 DM treated with empagliflozin presenting with asymptomatic bacteriuria, vertebral osteomyelitis and iliopsoas abscess due to Klebsiella pneumoniae. Case Report: We report a 73-year-old man with DM on empagliflozin who presented with back pain of 1-month duration with elevated inflammatory markers. On lumbar spine magnetic resonance imaging (MRI), he was found to have lumbar vertebral osteomyelitis and left iliopsoas abscess. His symptoms were improved with abscess drainage and antimicrobial therapy. The source of infection was most likely asymptomatic bacteriuria, which may have been secondary to empagliflozin treatment, as evidenced by the urine, the blood, the bone and abscess cultures revealing growth of Klebsiella pneumoniae with the same susceptibility profile. Conclusions: This particular case reinforces the significance of potential complications of DM and SGLT2 inhibitors’ adverse effects, especially the increased risk of infections, and can aid clinicians in expanding the differential and enabling them to reach an accurate diagnosis and appropriate management. Although vertebral osteomyelitis is a less common cause of back pain, physicians should keep it in the differential diagnosis whenever a patient’s back pain is chronic and associated with motor weakness.

Urinary schistosomiasis is one of the most important tropical diseases, which has received insufficient attention in developing countries. The burden of urinary schistosomiasis is further exacerbated by co-infection with bacterial Urinary Tract Infections (UTIs). This study was aimed at assessing bacteria co-infection and the impact of urinary schistosomiasis on daily activities of women in Yala L.G.A in Cross River State, Nigeria. Macroscopy, urinalysis, and microscopy were used to examine the 650 urine samples (400 from Okpoma and 250 from Ugaga villages) collected to determine presence of Schistosoma haematobium eggs. The presence of bacterial strains in urine samples positive for Schistosoma eggs was evaluated using standard microbiological protocol. Questionnaires administered to women provided information on socio-demographic data and water-contact activities. Results revealed that out of the 650 urine specimens examined in the two villages, 202 (31.08%) were infected as overall prevalence. The highest prevalence (48.53%) was found among the 11-22 years age group, and the least (12.80%) among the 59- 70 years age group. Statistical analysis at significance level (P≤ 0.05) revealed that there is a significant relationship between occupation and infection rate of schistosomiasis in the area. One hundred and sixty women (72.07%) who were infected complained of suprapubic pain and painful urination. Also, the infection prevented them from going to farm, market, carrying out their daily domestic activities (cooking, washing, fetching water), attending social functions, and performing their functions as caregivers. A total of eight (8) bacteria genera were isolated and identified from 202 urine samples positive for Schistosoma eggs. The bacterial species include Klebsiella sp. 3 (2.47%), Staphylococcus aureus 39 (32.23%), Enterococcus aerogenes 6 (4.95), Escherichia coli 32 (26,45), Pseudomonas aeruginosa 14 (11.57), Staphylococcus saprophyticus 10 (8.26), Enterococcus faecalis 9 (6.61) and Proteus sp. 8 (6.61). Significant bacteriuria was detected in 121 (59.90%) and co-infection was detected in 65 (53.68%) of schistosomiasis cases. This investigation revealed the impact of urinary schistosomiasis on the daily activities of the women and significant bacteriuria in the study area which suggest that bacterial presence may be a potent complication in the management of urinary schistosomiasis. The integration of complementary control strategies such as disease surveillance, chemotherapy, health education, potable water supply, provision of toilet facilities and sanitation in the study area would lead to great success..

INTRODUCTION: The objective of this study was to describe the incidence, microbiology, and risk factors related to infectious complications after transrectal prostate biopsies. METHODS: This was a single-center, retrospective cohort study of patients undergoing prostate biopsies. Throughout the study period, the institutional recommendation for antibiotic prophylaxis was cephalexin and ciprofloxacin. Due to the desire to limit fluoroquinolone use, the ciprofloxacin duration of therapy was reduced from 48 to 24 hours in the middle of the study period. The primary outcome was the incidence of infection-related complications, defined as a urinary tract infection (UTI) or bacteremia within 30 days post-procedure. RESULTS: A total of 1471 transrectal prostate biopsies were included. All patients received antibiotic prophylaxis, with 86.1% (1268/1472) of patients receiving both ciprofloxacin and cephalexin. The incidence of infection-related complications was 1.6% (24/1471). Four patients experienced bacteremia, all of which were due to E. coli, and all of these patients had received antibiotic prophylaxis with an active antibiotic. The use of ciprofloxacin was associated with a lower risk of infection-related complications (odds ratio [OR] 0.20, 95% confidence interval [CI] 0.07, 0.55). Bacteriuria within one year prior to the procedure was associated with increased risk of infection-related complications (OR 4.77, 95% CI 1.34, 16.93). Four (0.3%) patients experienced an antibiotic-related adverse event. CONCLUSIONS: We observed a low rate of infection-related complications and antibioticrelated adverse events in the setting of antibiotic prophylaxis with ciprofloxacin and cephalexin for 24 hours, without pre-procedure rectal culture screening. Investigation into procedural or host factors may uncover opportunities to further reduce infection-related complications. [ABSTRACT FROM AUTHOR]

Background: Acute kidney injury (AKI) is described as a loss of kidney filtration and excretory function over days or weeks, resulting in the retention of nitrogenous and other waste products ordinarily eliminated by the kidneys. The extent of the problem is so severe that one in every five adults and one in every three children globally develop AKI during hospitalization.¹ OBJECTIVES: 1. To study the clinical-epidemiological profile of patients presenting with Acute kidney injury to the emergency department 2. To find out the presumptive aetiology of AKI while the patient is in the Emergency department. MATERIAL & METHODS: Study Design: A Clinical Prospective Observational Study. Study area: The study was conducted in the Department of Emergency Medicine. Study Period: 1 year. Sample size: The study consisted of a total of 100 subjects. Sampling Technique: Simple Random technique. Study tools and Data collection procedure: Sample of Venous blood gas -- 1ml of venous blood in a 2ml heparinised syringe was used PHOX ULTRA MACHINE by Nova Medical was used for analysis of venous blood gas. Sample for renal function test of venous blood in serum vial collected and results obtained based on a spectrophotometer and calorimeter method. MODULAR P800 by ross company was used for the analysis of kidney function tests Sample for urine routine and microscopy- 5ml of urine collected in the sterile container. Results: Out of the 100 cases, 57 cases were admitted, 18 cases were discharged and 25 cases died in the emergency. Out of 57 admitted patients,22 patients received dialysis 16 patients were discharged and 5 patients died. The overall ED mortality associated with Acute kidney injury was 25 cases (25%). Out of 100 cases recruited, 75 cases were alive and 18 cases got discharged from emergency. Out of 25 deaths in ED, 21 cases had refractory metabolic acidosis, 16 cases had refractory septic shock and 11 cases had refractory hyperkalemia. CONCLUSION: In our investigation, we discovered that HRS and sepsis are the most common causes of acute kidney injury. HRS remains a disorder with a high death rate due to the co-morbidity of CLD. Common and critical illnesses necessitate prompt diagnosis and treatments, such as dialysis. Understanding the etiologies and factors influencing mortality outcomes can help with patient treatment, preventing the onset of AKI, and avoiding unnecessary deaths. [ABSTRACT FROM AUTHOR]

Diabetes is a systemic inflammatory condition. The modulation of cytokine levels caused by Asymptomatic Bacteriuria (ASB) infection can lead to altered inflammatory status in various tissues and may affect their homeostasis and function. We aim to estimate the cytokine (IL-6, TNF-α and IL-10) levels in serum of diabetic individuals with and without ASB to study their clinical significance. The current study evaluates the role of cytokines in inflammation caused due to ASB in T2DM patients. Increase in IL-6 and TNF-α levels may indicate renal tissue damage caused due to inflammation by ASB. Whereas increased IL-10 levels is a possible indicator of persistent infection with bacteria which may lead to diabetic renal disease. [ABSTRACT FROM AUTHOR]

Urinary tract infections (UTIs) are an extremely common pathology among pregnant women and women in labor, the manifestation of which occurs during pregnancy. Physiological changes in a woman’s organism form an optimal background for infection or activation of the aggression of one’s own microbial environments – the microflora that colonizes the periurethral area and mostly belongs to the family of enterobacteria and staphylococci. Clinical manifestations of UTIs during pregnancy are extremely variable and do not always correspond to the usual course of the disease, which necessitates the search for modern approaches to diagnosis and treatment. Also, UTI is one of the leading factors that provoke severe pregnancy complications and can lead to adverse obstetric outcomes. The objective: to evaluate the effectiveness of the modern etiopathogenetic approach to the treatment of UTIs during pregnancy. Materials and methods. In the study, which began in 2022 and is ongoing, 1615 pregnant women at gestational ages 6-37 weeks with clinical manifestations of urinary tract infections (UTIs). This work presents the survey results of 615 pregnant women with UTIs at gestational ages from 20 to 28 weeks, both before and one month after treatment initiation. These women were monitored during their pregnancies in prenatal care clinics of municipal non-commercial enterprises across all regions of Ukraine. At the stage of prescribing treatment the examined women are divided into two groups. The main group included 374 pregnant women with established diagnoses of acute urethritis, acute cystitis, gestational pyelonephritis (GP) and asymptomatic bacteriuria (ABU), who have received antibacterial and uroseptic agents for treatment in accordance with current clinical guidelines in combination with a herbal uroantiseptic containing 120 mg of cranberry berry extract and 36 mg each of extracts of goldenseal, lovage root, rosemary, as well as auxiliary substances. The comparison group included 241 pregnant women with established diagnoses of acute urethritis, acute cystitis, GP and ABU, who were treated exclusively with antibacterial and uroseptic agents for UTIs manifestations. The effectiveness of treatment methods was evaluated on the basis of a developed questionnaire with information on the main symptoms characteristic of diseases of the urinary system, before and one month after the prescribed treatment. Results. On the background of addition to the main antibacterial and uroseptic therapy the herbal uroantiseptic, containing 120 mg of cranberry berry extract and 36 mg each of extracts of yarrow, lovage root, rosemary, as well as auxiliary substances already a month after the start of treatment, the absence of complaints was found in the majority of pregnant women in the main group, related: with frequent urination – 354 (94.6%) (comparison group – 208 (86.3%); p<0.05), the need for urgent urination – 374 (99.1%) (comparison group – 232 (96.3%); p<0.05), the feeling of incomplete emptying of the bladder – 348 (93.3%) (comparison group – 202 (83.9%); p<0.05), with pain: during urination – 369 (98.7%) (comparison group – 231 (95.9%); p<0.05), in the lower abdomen, not associated with urination – 366 (97.9%) (comparison group – 230 (95.9%); p<0.05), in the lower back – 369 (98.7%) (comparison group – 229 (95.1%); p<0.05), with discharge from the urethra not related to urination – 374 (100.0%) (comparison group – 233 (96.7%); p<0.05). Conclusions. On the background of the prescribing of a herbal uroantiseptic containing 120 mg of cranberry extract and 36 mg of extracts of yarrow, lovage root, and rosemary, as well as auxiliary substances, additionally to the main antibacterial and uroseptic therapy in pregnant women of the main group, in a significantly greater number of cases the absence of complaints, which are associated with manifestations of urinary tract infections, was determined. The use of the herbal uroantiseptic, containing 120 mg of cranberry berry extract and 36 mg of extracts of yarrow, lovage root, and rosemary, is safe and creates favorable conditions for the course of pregnancy and further childbirth due to the potentiation of the effects of antibacterial and uroseptic therapy and the effective prevention of recurrences of urinary tract infections.

Abstract Introduction There is a relationship between excess body weight and the risk of a number of infectious diseases, including urinary tract infections (UTIs). This study aimed to investigate the correlation between body mass index (BMI) and UTIs among Prospective Epidemiological Research Studies of the Iranian Adults (PERSIAN) Guilan Cohort Study (PGCS) population. Methods This cross‐sectional study was conducted on 10,520 individuals aged 35–70 years from PGCS. The demographical data and clinical characteristics of the participants were recorded. Microscopic examination of the urine samples was performed to detect the presence of bacteria or white blood cells (WBC) as indicators of infection. UTI was defined as the presence of bacteria in the urine (Few, moderate, and many) and a value of ≥10 WBC/high power field (HPF) by light microscopy. Results The prevalence of UTIs in this study was 8.8%, with a higher incidence in females compared to males (12.2% vs. 4.7%, p

BackgroundBacterial urinary tract infections have been associated with comorbidities and increased antimicrobial resistance over time.ObjectiveTo identify bacterial species, antimicrobial susceptibility patterns and risk factors associated with antimicrobial resistance.AnimalsThree hundred sixty-three positive urine cultures from 308 cats.MethodsBacterial species and antimicrobial susceptibility data from positive aerobic bacterial urine cultures from cats with growth of ≥103 colony forming units per milliliter (cfu/ml) were included. Medical records were reviewed, and bacteriuria was classified as sporadic bacterial cystitis, recurrent bacterial cystitis or subclinical bacteriuria (SBU). Multivariable logistic regression analysis was used to evaluate antimicrobial resistance risk factors.ResultsA total of 444 bacterial isolates from 363 bacteriuric episodes were identified. Escherichia coli (52%) and SBU (59%) were the most common organism and classification, respectively. When compared to other classifications of bacteriuria, Enterococcus spp. were more likely to be isolated from SBU episodes (P 90% susceptible designation to all bacteria isolated highlighting the importance of performing urine culture and susceptibility testing, particularly for cats with recurrent bacterial cystitis.

BackgroundThe ability to detect bacteriuria in dogs with a point-of-care test might improve medical care and antimicrobial stewardship.Hypothesis and objectiveA rapid immunoassay (RIA; RapidBac) will provide acceptable sensitivity and specificity for diagnosis of bacteriuria.AnimalsForty-four client-owned dogs with a clinical indication for urinalysis and aerobic bacterial urine culture.MethodsProspective study. Urine, collected by cystocentesis, was submitted for urinalysis and culture at a diagnostic laboratory. Owners completed an enrollment questionnaire regarding their dogs' clinical signs. The RIA was performed according to the manufacturer's guidelines. Results were compared to culture.ResultsForty-four urine specimens were evaluated from 44 dogs. The sensitivity and specificity of the RIA test to detect bacteriuria compared to urine culture were 81.8% (95% CI, 65.7%-97.9%) and 95.5% (95% CI, 86.8%-99.9%), respectively. For cultures yielding ≥103  CFU/mL, sensitivity increased to 90.0% (95% CI, 76.9%-100%) and specificity was similar at 95.2% (95% CI, 86.1%-99.9%). Malodorous urine, bacteriuria, and pyuria were more likely to be present in dogs with positive RIA or urine culture results compared to dogs with negative results.Conclusions and clinical importanceThe RIA was easy to perform and had good sensitivity and excellent specificity in this group of dogs. The RIA might be a useful screening test for decision-making regarding antimicrobial therapy in dogs with a clinical indication for urine culture. Consideration could be given to amending the International Society for Companion Animal Infectious Disease definition of bacterial cystitis as the presence of signs of lower urinary tract disease together with positive culture or a positive RIA.

ObjectiveAs part of a project to implement antimicrobial dashboards at select facilities, we assessed physician attitudes and knowledge regarding antibiotic prescribing.DesignAn online survey explored attitudes toward antimicrobial use and assessed respondents' management of four clinical scenarios: cellulitis, community-acquired pneumonia, non-catheter-associated asymptomatic bacteriuria, and catheter-associated asymptomatic bacteriuria.SettingThis study was conducted across 16 Veterans' Affairs (VA) medical centers in 2017.ParticipantsPhysicians working in inpatient settings specializing in infectious diseases (ID), hospital medicine, and non-ID/hospitalist internal medicine.MethodsScenario responses were scored by assigning +1 for answers most consistent with guidelines, 0 for less guideline-concordant but acceptable answers and -1 for guideline-discordant answers. Scores were normalized to 100% guideline concordant to 100% guideline discordant across all questions within a scenario, and mean scores were calculated across respondents by specialty. Differences in mean score per scenario were tested using analysis of variance (ANOVA).ResultsOverall, 139 physicians completed the survey (19 ID physicians, 62 hospitalists, and 58 other internists). Attitudes were similar across the 3 groups. We detected a significant difference in cellulitis scenario scores (concordance: ID physicians, 76%; hospitalists, 58%; other internists, 52%; P = .0087). Scores were numerically but not significantly different across groups for community-acquired pneumonia (concordance: ID physicians, 75%; hospitalists, 60%; other internists, 56%; P = .0914), for non-catheter-associated asymptomatic bacteriuria (concordance: ID physicians, 65%; hospitalists, 55%; other internists, 40%; P = .322), and for catheter-associated asymptomatic bacteriuria (concordance: ID physicians, 27% concordant; hospitalists, 8% discordant; other internists 13% discordant; P = .12).ConclusionsSignificant differences in performance regarding management of cellulitis and low overall performance regarding asymptomatic bacteriuria point to these conditions as being potentially high-yield targets for stewardship interventions.

Abstract Pyuria in dipstick examination serves as the most widespread screening tool for urinary tract infections (UTI). The absence of pyuria, however, does not exclude UTI. We investigated the diagnostic value of urinary calprotectin, a mediator protein of the innate immune system, which is released by leukocytes, for the detection of UTI and compared it with dipstick pyuria. Since even low numbers of leukocytes in the urine significantly increase urinary calprotectin concentrations, calprotectin might be a more sensitive marker than pyuria detected by dipstick. All 162 patients were prospectively included and underwent a urine dipstick, urine culture, quantification of proteinuria and determination of calprotectin in the urine. Urinary calprotectin was determined using an enzyme-linked immunosorbent assay (ELISA). UTI was defined as urine cultures with detection of one or a maximum of two uropathogenic bacteria with ≥ 105 colony-forming units per millilitre (CFU/ml). Exclusion criteria were acute kidney injury, chronic renal insufficiency and tumors of the urinary tract. 71 (43.8%) patients had a UTI. Of the 91 patients without UTI, 23 had a contamination and 19 had evidence of ≥ 105 CFU/ml considered to be asymptomatic bacteriuria. The median calprotectin concentration in patients with UTI and pyuria was significantly higher than in patients with UTI and without pyuria (5510.4 vs. 544.7 ng/ml). In ROC analyses, calprotectin revealed an area under the curve (AUC) of 0.70 for the detection of significant bacteriuria. Pyuria in dipstick examinations provided an AUC of 0.71. There was no significant difference between these AUCs in the DeLong test (p = 0.9). In patients with evidence of significant bacteriuria but without pyuria, a significantly higher calprotectin concentration was measured in the urine than in patients with neither pyuria nor UTI (544.7 ng/ml vs 95.6 ng/ml, p = 0.029). Urinary calprotectin is non-inferior to dipstick pyuria in the detection of UTI.

The present study aimed to evaluate the concepts of epidemiology, uropathogenic, diagnosis, prevention, and treatment of urinary tract infections (UTI) in humans. One of the most frequent infections that affect people is UTIs. During childhood they are equally common in boys and girls, and after that, they are more common in girls. In both of the general population and hospital environment, women frequently experienced at least one UTI in their lifetime. The existence of bacteriuria and pyuria are the 2 most significant signs of UTIs. Frequent urination, pain during urination, and soreness in the side or lower back are among the main symptoms of UTI. These infections are classified into 3 primary types: asymptomatic bacteriuria, lower UTI (cystitis), and febrile upper UTI (acute pyelonephritis), because such classification supports understanding of the infection‟s etiology. UTI can be diagnosed through a combination of positive urine tests and/or culture and symptoms. Dipstick urinalysis is widely used due to its ease of availability and utility; however, the outcomes must be evaluated by considering the patient‟s pretest probability depending on the characteristics and symptoms. Most UTIs can be treated with antibiotics such as Amoxicillin, cephalexin, and doxycycline. But the Gram-positive bacterium (Enterobacter faecalis) exhibited great resistance to erythromycin, while the Gram-negative bacterium (Escherichia coli) displayed great resistance to ampicillin. So, there is an urgent need for a combination between organic treatments and antibiotics to treat the complicated UTI. For example, the plant-based treatments, such as cranberry juice, are efficient in treating the UTI and can be used as an alternative to combating the bacteria that cause UTI.

BackgroundUrinary tract infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (ESBL-E. coli) may occur as outbreaks due to common-source exposures. Yet, it is currently unknown if they cluster geographically as would be expected as part of an outbreak.MethodsWe collected electronic health record data on all patients living in San Francisco with culture-documented community-onset E. coli bacteriuria in a safety-net public healthcare system from January 2014 to March 2020 (diagnosed

Introduction: Bacterial urinary tract infections (UTI) and some sexually transmitted infections (STI) can have overlapping signs and symptoms or nonspecific findings, such as pyuria on urinalysis. Furthermore, results from the urine culture and the nucleic acid amplification test for an STI may not be available during the clinical encounter. We sought to determine whether gonorrhea, chlamydia, and trichomoniasis are associated with bacteriuria, information that might aid in the differentiation of STIs and UTIs. Methods: We used multinomial logistic regression to analyze 9,650 encounters of female patients who were aged ≥18 years and who underwent testing for STIs. The ED encounters took place from April 18, 2014-March 7, 2017. We used a multivariable regression analysis to account for patient demographics, urinalysis findings, vaginal wet-mount results, and positive or negative (or no) findings from the urine culture and testing for Neisseria gonorrhoeae, Chlamydia trachomatis, or Trichomonas vaginalis. Results: In multivariable analysis, infection with T vaginalis, N gonorrhoeae, or C trachomatis was not associated with having a urine culture yielding 10,000 or more colony-forming units per mililiter (CFU/mL) of bacteria compared with a urine culture yielding less than 10,000 CFU/mL or no urine culture obtained. The diagnosis of a UTI in the ED was not associated with having a urine culture yielding 10,000 or more CFU/mL compared with a urine culture yielding less than 10,000 CFU/mL. Conclusion: After adjusting for covariates, no association was observed between urine culture results and testing positive for trichomoniasis, gonorrhea, or chlamydia. Our results suggest that having a concurrent STI and bacterial UTI is unlikely. [ABSTRACT FROM AUTHOR]

(1) Background: Urinary tract infections (UTIs) are among the most frequent complications in kidney transplant (KT) recipients. Asymptomatic bacteriuria (ASB) may be a risk factor for UTIs and graft rejection. We aimed to evaluate available evidence regarding the benefit of screening and treatment of ASB within the first year after KT. (2) Evidence acquisition: A systematic literature search was conducted in MEDLINE, the Cochrane Library CENTRAL and Embase. Inclusion criteria were manuscripts in English addressing the management of ASB after KT. The PICO questions concerned Patients (adults receiving a KT), Intervention (screening, diagnosis and treatment of ASB), Control (screening and no antibiotic treatment) and Outcome (UTIs, sepsis, kidney failure and death). (3) Evidence synthesis: The systematic review identified 151 studies, and 16 full-text articles were evaluated. Seven were excluded because they did not evaluate the effect of treatment of ASB. There was no evidence for a higher incidence of lower UTIs, acute pyelonephritis, graft loss, or mortality in patients not treated with antibiotics for ASB. Analysis of comparative non-randomized and observational studies did not provide supplementary evidence to guide clinical recommendations. We believe this lack of evidence is due to confounding risk factors that are not being considered in the stratification of study patients. [ABSTRACT FROM AUTHOR]

Background: Urinary tract infections (UTIs) are the inflammatory disorders of the urinary tract caused by the abnormal growth of pathogens. Urinary tract infection is known to cause short-term morbidity in terms of fever, dysuria, and lower abdominal pain (LAP) and may result in permanent scarring of the kidney. The presence of bacteria in the urine, known as bacteriuria, may be indicative of infection or colonization of the urinary tract, but it may also be due to bacterial contamination occurring during collection of a specimen. Aim: The present study was done in order to identify the bacteria causing urinary tract infections from female patients attending Ruhengeri Referral Hospital. Methodology: A cross sectional study was conducted on female patients who were attending Ruhengeri Referral Hospital in a period of two months from October to November 2021. Urine samples were collected from patients who were requested to urinary test with respect to standard procedures. Samples were processed and analyzed at INES-Ruhengeri microbiology laboratory where gram stain and culture as well as biochemical test were performed in order to make microbial identification. From the results patients who were found with UTI, their structured questionnaire was taken into consideration in order to determine the associated risk factors. The data on risk factors were collected using questionnaire that were designed in the preferred language. Data were collected and analysed using statistical package for social science, Microsoft excel, and the presentation of results was done using tables. Results: The outcomes of the study indicated that E.coli, K. pneumonia, P. aeruginosa, Enterobacter ssp and S. saprophyticus were isolated from patients urine sample where E. coli is more present in patients sample where it has been found at 60%(18) samples. The least isolated bacteria in patient’s samples are Enterrobacter spp and S. saprophyticus at frequency of 2(6.7) per each bacterium. The risk factor associated with urinary tract infection in female patients attended Ruhengeri referral hospital in a period of study, the results indicated that douching in secret parts twice a day is associated with urinary tract infection with P-value equivalent to 0.001. Conclusion: This study was intended to assess the urinary tract infection among female patients attending Ruhengeri referral hospital. The study findings indicated that E.coli, K. pneumonia, P. aeruginosa, Enterobacter ssp and S. saprophyticus are more likely to be found in urinary tract of female patients. The study finding has indicated also that poor hygienic life style increases the risk of being infected by urinary tract infections. [ABSTRACT FROM AUTHOR]

Objective: To determine the frequency of asymptomatic bacteriuria (ASB), causative pathogens and antibiotic sensitivity pattern in antenatal women. Study Design: Cross-sectional study. Setting: Department of Obstetrics and Gynaecology, Nishtar Hospital, Multan, Pakistan. Period: February 2022 to July 2023. Methods: A total of 110 women with singleton pregnancy with gestational age 13-42 weeks, and aged 18 to 40 years were included. Once the patients were enrolled, demographic characteristics (age, gestational age, parity (primiparous or multiparous), body mass index (BMI), place of living (rural or urban), gestational diabetes mellitus (yes or no), educational status (illiterate, primary, middle, matric, or graduate)) were noted. Presence or absence of asymptomatic bacteriuria was noted. Results: In a total of 110 pregnant females, the mean age and gestational age were 28.7±3.9 years and 29.4±4.0 weeks, respectively. The frequency of ASB among pregnant women was found in 19 (17.3%) patients. The frequency of causative pathogens showed that E. coli was the most frequent isolates noted among 7 (36.8%) women while staphylococcus aureus, Klebsiella, pseudomonas spp, and Proteus spp were identified in 5 (26.3%), 4 (21.0%), 2 (10.5%), and 1 (5.26%) respectively. Antibiotic susceptibility patterns revealed that Amikacin, Nitrofurantoin, cephalexin, and Ciprofloxacin were the most sensitive antibiotics noted in 18 (94.7%), 17 (89.5%), 15 (79.0%) and 14 (73.7%) samples respectively. Conclusion: The frequency of asymptomatic bacteriuria in pregnant women is high with E. coli as the most common causative organism. Antibiotic susceptibility patterns revealed that Amikacin, Nitrofurantoin, cephalexin, and Ciprofloxacin to have good sensitivities. [ABSTRACT FROM AUTHOR]

Background and Aims: Antibiotic resistance presents a significant global public health challenge, particularly for urinary tract infections (UTIs), and is notably severe in developing countries. Surveillance of the antimicrobial susceptibility patterns of UTI‐causing bacteria is crucial for effective treatment selection. This study aimed to analyze these patterns in bacteria isolated from the urine samples of patients at Mughda Medical College Hospital, Dhaka, Bangladesh. Methods: A retrospective study (January 2019 to December 2020) at Mugdha Medical College and Hospital, Dhaka, examined clinical and laboratory data from patients with positive urine cultures (≥105 CFU/mL). The study classified patients into four age groups: children (1–<18 years), young adults (18–<33 years), middle‐aged adults (33–50 years), and old adults (>50 years). The standard Kirby‐Bauer method was used to assess antibiotic sensitivity to 28 common antibiotics. Results: Among 243 positive urine cultures in both community‐ and hospital‐acquired UTIs, Escherichia coli was the most common uropathogen (65.84%), followed by Klebsiella spp. (12.34%), Enterococcus spp. (8.23%), and other types of bacteria. Conclusion: Old adults are particularly vulnerable to UTIs, with E. coli being the predominant causative agent in the study region. The observed antimicrobial resistance patterns underscore the necessity of judicious antibiotic selection to effectively treat UTIs across different age groups. [ABSTRACT FROM AUTHOR]

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.

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. [ABSTRACT FROM AUTHOR]

Background: Asymptomatic bacteriuria (ASB) during pregnancy can lead to symptomatic urinary tract infection (UTI), with increased fetal and maternal morbidity and mortality. We evaluated the incidence, clinical and microbiological profile, and outcome of ASB in pregnant women attending our antenatal clinic. Materials and Methods: This prospective study was conducted on 3769 pregnant women in a routine antenatal clinic at a tertiary care center. Participants were divided into two groups, ASB and non-bacteriuria. Data were collected in a standard proforma and analyzed using the software Statistical Package for the Social Sciences (SPSS) v. 20. Results: The incidence of ASB was 3.29% (124/3769). Majority of the women were in the age group of 21-30 years (78.76%, n = 89). Escherichia coli (61.06%) was the most common organism isolated. Maternal anemia (30.08% and 2.93% in the ASB and non-bacteriuria groups, respectively), low birth weight (LBW; 42.5% and 27.98% in the ASB and non-bacteriuria groups, respectively), intrauterine death (4.4% and 1.4% in the ASB and non-bacteriuria groups, respectively), and preterm delivery (37.2% and 22.31% in the ASB and non-bacteriuria groups, respectively) were were associated with ASB (P = 0.001). Conclusion: ASB was associated with maternal anemia, preterm delivery, intrauterine death, and LBW. Early detection and treatment of ASB may result in favorable maternal outcome.

Urinary tract infections (UTIs) are a leading infectious cause of emergency department admission. Early UTI diagnosis is challenging, and a faster, preferably point-of-care urine analysis is necessary. We aimed to evaluate the diagnostic accuracy of urine flow cytometry (UFC) and urine dipstick analysis (UDA) in identifying bacteriuria and UTIs. This study included adults suspected of an infection admitted to three Danish emergency departments. UFC and UDA were the index tests, and urine culture and an expert panel diagnosis were the reference tests. We used logistic regression and receiver operator characteristics curves to find each test's optimal model and cut-off. We enrolled 966 patients and performed urine cultures on 786. Urine culture was positive in 337, and 200 patients were diagnosed with a UTI. The UFC model ruled out bacteriuria in 10.9% with a negative predictive value (NPV) of 94.6% and ruled out UTI in 38.6% with an NPV of 97.0%. UDA ruled out bacteriuria in 52.1% with an NPV of 79.2% and UTI in 52.8% with an NPV of 93.9%. Neither UFC nor UDA performed well in ruling out bacteriuria in our population. In contrast, both tests ruled out UTI safely and in clinically relevant numbers. [ABSTRACT FROM AUTHOR]

OBJECTIVE To describe the clinical findings, microbiological data, treatment, and outcome of a population of cats with suspected acute pyelonephritis (APN). ANIMALS 32 client-owned cats. CLINICAL PRESENTATION AND PROCEDURES Retrospective case series from 2 veterinary teaching hospitals between January 1, 2014, and December 31, 2020. Cats were included if they had a positive bacterial urine culture and a clinical diagnosis of acute kidney injury. RESULTS Older female cats with underlying chronic kidney disease have a higher probability to develop bacterial culture–positive acute kidney injury or APN. Escherichia coli was the most commonly cultured bacterial species, and E coli isolates with susceptibility testing were resistant to amoxicillin-clavulanate but susceptible to fluoroquinolones or third-generation cephalosporins. Of the 20 cats with available follow-up information in the medical record, 14 were alive at 3 months after hospital discharge. Markers of renal function including creatinine (P = .008), BUN (P = .005), and phosphorus (P < .001) at the time of presentation were all higher in nonsurvivors compared with survivors. CLINICAL RELEVANCE The survival rate with feline APN is higher than previous reports of acute kidney injury when all etiologies are considered. Nonsurvivors had more pronounced azotemia upon initial presentation. Amoxicillin-clavulanate was a poor empirical antimicrobial in this cohort based on the microbiological data.
