Abstract
Multidrug resistance is a paramount impediment to successful treatment of most hospital acquired bacterial infections. A plethora of bacterial genera exhibit differential levels of resistance to the existing antibiotics. Prevalent Uropathogenic Escherichia coli or UPEC conduce high mortality among them. Multi-Drug Resistant bacterial strains utilize precise mechanisms to bypass effects of antibiotics. This is probably due to their familiar genomic origin. In this article drug repositioning method have been utilised to target 23 enzymes of UPEC strains viz. CFT073, 536 and UTI89. 3-D drug binding motifs have been predicted using SPRITE and ASSAM servers that compare amino acid side chain similarities. From the hit results anti-viral drugs have been considered for their uniqueness and specificity. Out of 14 anti-viral drugs 3 anti-HIV drugs viz. Amprenavir, Darunavir and Saquinavir have selected for maximum binding score or drug targetability. Finally, active sites of the enzymes were analyzed using GASS-WEB for eloquent drug interference. Further analyses with the active sites of all the enzymes showed that the three selected anti-HIV drugs were very much potent to inhibit their active sites. Combination or sole application of Amprenavir, Darunavir and Saquinavir to MDR-UPEC infections may leads to cure and inhibition of mortality.

Abstract
Currently, urinary tract infection (UTI) diagnosis focuses on planktonic cell detection rather than biofilm detection, but the facile identification of UPEC bacterial biofilms is crucial in UTI diagnosis as the biofilm formed by bacteria is the causative agent of recurrent and chronic UTIs. Therefore, in this work, we developed a simple, cost-effective, colorimetric, and electrochemical-based strategy for the detection of cellulose in urine. Cellulose, a biofilm matrix component, was detected using tyrosine-capped gold and silver nanoparticles through a visible colorimetric change with a decrease in the absorbance intensity and a decrease in current response in the case of cyclic voltammetry. The sensor displayed a linear detection range of 10-70 mg mL-1 for colorimetry and 10-300 μg mL-1 for cyclic voltammetry with a good selectivity of <2.8% and a recovery rate of 95-100% in real-time sample analysis. Moreover, the binding affinity of cellulose with tyrosine was investigated using molecular docking studies to validate the sensing mechanism. We anticipate that our work will aid clinicians in the implementation of rapid, cost-effective, and definitive diagnosis of UTIs.

Stair SL, Yoon JH, Dymanus KA, Lee UJ, Adelstein SA. Fecal incontinence is not associated with UTI: A contemporary case-control study. Neurourol Urodyn 2024. [PMID: 39045766 DOI: 10.1002/nau.25544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 05/14/2024] [Accepted: 06/26/2024] [Indexed: 07/25/2024]
Abstract
INTRODUCTION Urinary tract infections (UTIs) are a leading cause of infection in adults. The most common cause is gastrointestinal bacteria ascending the urethra into the bladder. Studies showing fecal incontinence (FI) is a risk factor for UTI have been limited to nursing home populations. Healthy patients with recurrent UTI, especially women, often receive counseling, suggesting improper personal hygiene contributes to UTIs. This advice can be stigmatizing. Given UTI prevalence, it is important to elucidate risk factors for improved diagnosis, treatment, and patient education. Our objective was to perform a hospital-centered, retrospective case-control analysis to assess the effect of FI on UTI development in ambulatory patients. METHODS Patients (n = 3035) with a diagnosis of FI were identified from a single institution and propensity score-matched with screening colonoscopy patients (n = 3035) from 2018 to 2021. Patients were matched on age, sex, race, ethnicity, body mass index, and comorbidities, for example, diabetes, vesicoureteral reflux, and urinary incontinence. The association between FI and UTI was tested using Pearson's χ2 test. RESULTS Median age was 64 years with more females than males (73.81% vs. 71.20% female for case/control, p = 0.02). Patients with FI were more often to have concurrent urinary incontinence (18.62% vs. 10.25% for case/control, p < 0.001), as well as specifically urgency incontinence (13.28% vs. 11.57% for case/control, p = 0.04). There was no significant difference in the incidence of UTI between patients with FI and those presenting for screening colonoscopy (p = 0.44). CONCLUSION FI was not associated with an increased number of UTIs. Based on our results, current stigmatizing beliefs regarding the association between FI and UTI should be reevaluated.

Abstract
OBJECTIVE To analyse trends in urinary tract infection (UTIs) hospitalisation among patients adults 18-65 aged in Spain from 2000-2015. METHODS Retrospective observational study using the Spanish Hospitalisation Minimum Data Set (CMBD), with codifications by the International Classification of Diseases (ICD-9). Variables: Type of UTIs (pyelonephritis, prostatitis, cystitis and non-specific-UTIs), sex, age (in 5 categories: 18-49 and 50-64 years in men, and 18-44, 45-55 and 56-64 years in women), comorbidity, length of stay, costs and mortality associated with admission. The incidence of hospitalisation was studied according to sex, age group and type of UTIs per 100,000. Trends were identified using Joinpoint regression. RESULTS From 2000-2015, we found 259,804 hospitalisations for UTIs (51.6% pyelonephritis, 7.5% prostatitis, 0.6% cystitis and 40.3% non-specific UTIs). Pyelonephritis predominated in women and non-specific UTIs in men. The hospital stay and the average cost (2,160 EUR (IQR 1,7872,540 were greater in men. Overall mortality (0.4%) was greater in non-specific UTIs. More women were admitted (rates of 79.4 to 81.7) than in men (30.2 to 41). The greatest increase was found in men aged 50-64 years (from 59.3 to 87). In the Joinpoint analysis, the incidence of pyelonephritis increased in women [AAPC 2.5(CI 95% 1.6;3.4)], and non-specific UTIs decreased [AAPC -2.2(CI 95% -3.3;-1.2)]. Pyelonephritis decreased in men [AAPC -0.5 (CI 95% -1.5;0.5)] and non-specific UTIs increased [AAPC 2.3 (CI 95% 1.9;2.6)] and prostatitis increased [AAPC 2.6 (CI 95% 1.4;3.7)]. CONCLUSIONS The urinary infection-related hospitalisation rate in adults in Spain increased during the period 2000-2015. Pyelonephritis predominated in women and non-specific UTIs in men. The highest hospitalisation rates occurred in the women but the greatest increase was found in men aged 65-74. The lenght of stay and cost were higher in men.

Abstract
Introduction Urinary tract infections (UTIs) are globally prevalent. This study explores the clinical and pathological profile of culture-positive UTI patients at Sri Jayewardenepura General Hospital. Method In this descriptive cross-sectional study conducted at Sri Jayewardenepura General Hospital from December 2020 to May 2021, we evaluated patients over 14 years with positive urine culture reports. Excluding those with HIV, undergoing chemotherapy, or pregnant, we used consecutive sampling. Data were collected via interviewer-administered questionnaires and analyzed using SPSS version 21.0 (IBM Inc., Armonk, New York), employing descriptive statistics and Fisher's exact tests to identify factors associated with urinary tract infections. Results The study involved approximately 278 participants. The mean age remained 60 ± 20.279 years, with over half of the participants being female. Common symptoms like fever and lower abdominal pain were observed in 22.30% of cases. The incidence of acute kidney injury was 30.58%. Escherichia coli (36%) and Klebsiella pneumoniae (26%) were the predominant organisms found. Indwelling catheters and other urinary tract conditions were considered risk factors. Patients with at least one risk factor were more likely to receive antibiotics before the urine culture. Similarly, males exhibited a higher prevalence of at least a risk factor than females. Conclusion UTIs are a significant clinical issue in older populations, with females being more susceptible. Fever and abdominal pain were common symptoms. Escherichia coli and Klebsiella pneumoniae were the most frequent causative agents. Further research is necessary to identify risk factors and predictors of antimicrobial resistance in UTI patients.

Abstract
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
Proteus mirabilis, a prevalent urinary tract pathogen and formidable biofilm producer, especially in Catheter-Associated Urinary Tract Infection, has seen a worrying rise in multidrug-resistant (MDR) strains. This upsurge calls for innovative approaches in infection control, beyond traditional antibiotics. Our research introduces bacteriophage (phage) therapy as a novel non-antibiotic strategy to combat these drug-resistant infections. We isolated P2-71, a lytic phage derived from canine feces, demonstrating potent activity against MDR P. mirabilis strains. P2-71 showcases a notably brief 10-minute latent period and a significant burst size of 228 particles per infected bacterium, ensuring rapid bacterial clearance. The phage maintains stability over a broad temperature range of 30-50°C and within a pH spectrum of 4-11, highlighting its resilience in various environmental conditions. Our host range assessment solidifies its potential against diverse MDR P. mirabilis strains. Through killing curve analysis, P2-71's effectiveness was validated at various MOI levels against P. mirabilis 37, highlighting its versatility. We extended our research to examine P2-71's stability and bactericidal kinetics in artificial urine, affirming its potential for clinical application. A detailed genomic analysis reveals P2-71's complex genetic makeup, including genes essential for morphogenesis, lysis, and DNA modification, which are crucial for its therapeutic action. This study not only furthers the understanding of phage therapy as a promising non-antibiotic antimicrobial but also underscores its critical role in combating emerging MDR infections in both veterinary and public health contexts.

FUJITA MEDICAL JOURNAL 2024; 10:24-29. [PMID: 38332777 PMCID: PMC10847634 DOI: 10.20407/fmj.2023-012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 07/25/2023] [Indexed: 02/10/2024]
Abstract
Objectives Multidrug-resistant (MDR) bacterial infections are highly prevalent among long-term care facility (LTCF) residents, and are thus important targets for antimicrobial stewardship. Diagnoses of urinary tract infections (UTIs), which are associated with antimicrobial use in these facilities, are not always made by physicians. Past epidemiologic studies have included asymptomatic bacteriuria together with UTIs. The National Healthcare Safety Network has initiated a surveillance program to identify the causative organisms of UTIs in LTCF residents. In Japan, medical care for these residents is provided through in-person physician visits; however, limited related data are available. Therefore, we investigated the organisms causing UTIs and their drug susceptibility among LTCF residents in central Japan, and examined the prevalence of multidrug resistance, its risk factors, and correlations with clinical outcomes. Methods We retrospectively evaluated clinical and urine culture data of LTCF residents with physician-diagnosed UTIs between April 1, 2019, and April 30, 2022. Results The detection rate of multidrug-resistant organisms was high, with Escherichia coli being the most prevalent. Ceftriaxone was frequently used for initial therapy. The initial antimicrobial agents were significantly less active against MDR pathogens than non-MDR pathogens. Most residents continued to receive the initial agents regardless of culture results. Nonetheless, differences in the therapy duration, relapse and hospitalization rates, and death rate within 28 days between the multidrug-resistant and non-multidrug-resistant groups were not significant. Conclusions Antimicrobial stewardship is essential for reducing antimicrobial use and selective pressure in LTCFs in Japan; however, more specific data are needed for its effective implementation.

Presence of fimH and iss type 1, 2 and 3 genes in uropathogenic Escherichia coli isolates recovered from an apex medical institute in North India. Indian J Med Microbiol 2023; 46:100417. [PMID: 37945109 DOI: 10.1016/j.ijmmb.2023.100417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 06/13/2023] [Accepted: 06/17/2023] [Indexed: 11/12/2023]
Abstract
PURPOSE To detect the presence of fimH and iss type 1, 2 and 3 genes in uropathogenic Escherichia coli (UPEC) isolates recovered from patients coming to the out patient department (OPD) of our hospital. METHODS E. coli isolates recovered from patients who had symptoms of urinary tract infection (UTI) were processed for the presence of fimH and iss genes. DNA was extracted using an in house method after which conventional PCR using forward and reverse primers targeting the four genes was carried out. The amplified products were electrophoresed and visualized in a gel documentation imager. Relevant demographic details of the patients were recorded on a pre-designed pro-forma and antimicrobial susceptibility testing of the isolates was done by disc diffusion method. RESULTS fimH was present in 87.5% of UPEC isolates whereas iss type 1 was seen in 7.3%, type 2 in 4.2% and iss type 3 in 71.9% isolates. Age of the patients ranged from 3 months to 82 yrs (mean 43.5 SD ± 18.20). UTI was more common in females (60.2%) as compared to males patients (39.8%). Dysuria (66.7%) was the most common symptom in the studied subjects and diabetes mellitus (42.6%) the most common co-morbidity. A total of 56.5% patients gave a history of prior antibiotic intake. The UPEC isolates were resistant to most of the antibiotics tested. However all the isolates were sensitive to polymyxin B and colistin. Fosfomycin resistance was seen in 9.5% of the UPEC isolates harbouring fimH gene. CONCLUSION This is the first study that highlights the presence of iss type 3 gene in UPEC isolates along with the fimH and iss type 1 and 2 genes. The results of this study can serve as a stepping stone for future in depth research into the significance of the iss genes in causing UTI.

Abstract
Background Acute kidney injury (AKI) is a well-known complication for hospitalized patients. Sepsis and various infections play a significant role in increasing the incidence of AKI. The present study evaluated the risk for Multidrug-resistant (MDR) infections and its effect on the incidence of AKI, hospitalization, need for dialysis, and mortality. Methods In a retrospective study design, data were collected from all adult patients with a positive multi-drug resistant culture who were admitted to King Abdullah University Hospital (KAUH). Records of 436 patients were reviewed between January 2017 - December 2018 with at least one year of follow-up. Results The mean age was 57.3 years (SD± 23.1), and 58.5% were males. The most common source of positive cultures was sputum, with 50% positive cultures. The incidence of AKI was 59.2%. The most isolated microorganism was Acinetobacter baumannii (76.8%), followed by Pseudomonas aeruginosa (14.9%).On multivariate analysis, age (OR 1.1, 95% CI 1.1-1.2, P=0.001), HTN (OR 1.8, 95% CI 1.0-3.3, P=0.02), DM (OR 1.1, 95% CI 0.6-1.9, P=0.69) and the use of Foley catheter on chronic bases (OR 4.3, 95% CI 2.6-6.8, P<0.0001) were strong predictors of AKI. Among patients with AKI, 74.4% died compared to 44.4% among non-AKI patients (p<0.001). Conclusion In patients with MDR, AKI incidence, hospitalization, and mortality were high. Early detection and addressing the problem may decrease bad outcomes, and health education for reducing antibiotic abuse is needed to lower MDR.

Chronic Kidney Disease-An Underestimated Risk Factor for Antimicrobial Resistance in Patients with Urinary Tract Infections. Biomedicines 2022; 10:biomedicines10102368. [PMID: 36289631 PMCID: PMC9598187 DOI: 10.3390/biomedicines10102368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 09/18/2022] [Accepted: 09/19/2022] [Indexed: 11/21/2022] Open
Abstract
(1) Background: Chronic kidney disease (CKD), as well as antimicrobial resistance (AMR) represent major global health problems, with important social and economic implications. It was reported that CKD is a risk factor for antimicrobial resistance, but evidence is scarce. In addition, CKD is recognized to be a risk factor for complicated urinary tract infections (UTIs). (2) Methods: We conducted an observational study on 564 adult in-hospital patients diagnosed with urinary tract infections. The aim of the study was to identify the risk factors for AMR, as well as multiple drug resistance (MDR) and the implicated resistance patterns. (3) Results: The mean age was 68.63 ± 17.2 years. The most frequently isolated uropathogens were Escherichia coli strains (68.3%) followed by Klebsiella species (spp. (11.2%). In 307 cases (54.4%)), the UTIs were determined by antibiotic-resistant bacteria (ARBs) and 169 cases (30%) were UTIs with MDR strains. Increased age (≥65) OR 2.156 (95% CI: 1.404−3.311), upper urinary tract obstruction OR 1.666 (1.083−2.564), indwelling urinary catheters OR 6.066 (3.919−9.390), chronic kidney disease OR 2.696 (1.832−3.969), chronic hemodialysis OR 4.955 (1.828−13.435) and active malignancies OR 1.962 (1.087−3.540) were independent risk factors for MDR UTIs. In a multivariate logistic regression model, only indwelling urinary catheters (OR 5.388, 95% CI: 3.294−8.814, p < 0.001), CKD (OR 1.779, 95% CI: 1.153−2.745, p = 0.009) and chronic hemodialysis (OR 4.068, 95% 1.413−11.715, p = 0.009) were risk factors for UTIs caused by MDR uropathogens. (4) Conclusions: CKD is an important risk factor for overall antimicrobial resistance, but also for multiple-drug resistance.

Front Cell Infect Microbiol 2022; 12:891796. [PMID: 35899043 PMCID: PMC9309389 DOI: 10.3389/fcimb.2022.891796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 06/08/2022] [Indexed: 11/29/2022] Open
Abstract
Microbiological diagnostics is of great importance in limiting the spread of nosocomial infections. The information on etiological agents of infections and their susceptibility to antibiotics enables a quick response in the case of a suspected epidemic outbreak. The aim of this study is to analyze the incidence of nosocomial urinary tract infections among patients hospitalized in hospital wards over a period of 2 years and to determine the predominant etiological agent depending on the method of clinical specimen collection. Data from the Mazovian Specialist Hospital (MSH) in Radom constitute the material for the preparation of this study. Urine was collected using two methods. The first one was the method of collecting urine from the central stream, while the second method was urine collected from patients with a urinary catheter in place. The statistical calculations were conducted using the statistical software. Based on hospital data, it was shown that 5,870 urine tests were performed during the period under review, of which 2,070 were positive. The number of positive results in 2021 decreased by 2.84% compared to that in 2020. On the basis of the statistical analysis, differences in the occurrence of multiple strains were observed between catheter-based and midstream urine collection. Differences were observed especially for Acinetobacter baumannii, Candida albicans, Escherichia coli, and Pseudomonas aeruginosa. A. baumannii, C. albicans, and P. aeruginosa were significantly more frequently found in urine samples collected through the catheter than from the midstream. Furthermore, E. coli (51.56%) and Enterococcus species (25.46%) were more frequent when collected from the middle stream than when urine was collected through a catheter. However, for the strain K. pneumoniae, the results were comparable when urine was collected from catheterized patients (13.83%) and from midstream (13.35%). Urinary tract infection among hospitalized patients of the Mazovian Specialist Hospital in Radom was diagnosed quite frequently. In 2021, 32 more urine cultures were performed than in 2020. In the analyzed period, among all ordered urine cultures, 35.27% of samples were positive.
