This study aims to determine the prevalence and characterize ESBLs and carbapenamase producing Enterobactericeae. Method: A cross-sectional study was carried out in Gertrude’s Children’s Hospital, Nairobi. 238 urine samples were collected from patients with urinary symptoms attending the outpatient department within the period 2020-2021. The urine were examined macroscopically and microscopically. Identification and antimicrobial susceptibility testing were done using VITEK® 2 Compact system (BioMérieux). Double disc synergy test and modified hodge tests were done as confirmatory tests for ESBLs and Carbapenamase phenotypes respectively. Polymerase Chain Reaction was used for the detection of blaCTX-M, blaTEM, blaSHV, blaKPC and blaOXA-48 genes. Results: From the 238 children sampled the prevalence of UTI caused by Enterobactericeae was 22.3%. The Enterobacteriaceae species isolated were Escherichia coli (84.9%), Klebsiella pneumoniae (5.66%), Proteus mirabillis (5.66%), Enterobacter aerogenes (1.89%) and Morganella morganii (1.89%). The isolated species were resistant to ampicillin. Meropenem had the highest susceptibility. Only E. coli species had the ESBLs (26.4%) and carbapenamase (1.9%) phenotypes. 100% had BlaCTX-M while 50% had blaTEM resistant gene. There was a significant association (p Conclusion: Ampicillin resistance resulted to use of alternative drugs and Meropenem was the drug of choice where increased resistance to the recommended drugs was noted. Further research on resistant genes is recommended.展开更多

The aim of our work was to establish the epidemiological and bacteriological profile of UTIs in children and then to study the sensitivity of the bacterial strains isolated to antibiotics. Materials and methods: This is a retrospective descriptive study over 3 years (2019-2022), including all cytobacteriological examination of urine (CBEU), performed in children aged 3 months to 14 years, admitted and treated for UTI, in the pediatric emergency department of Mohamed VI University Hospital. Results: A total of 239 children were included in our study. The mean age was 26 months. The sex ratio was 1.08. Escherichia coli was the most isolated bacterial strain in 79% of samples. The tested strains showed a high level of sensitivity to susceptibility rate toward amikacin (91%) and ciprofloxacin (100%) and whereas the level of resistance was high to the most current recommended antibiotics, mainly beta-lactams. Management was based, in severe forms of pyelonephritis, dual antibiotic therapy based on Third-generation cephalosporins combined with gentamycin. Favorable outcome was noted in 94% of children. Conclusion: Awareness-raising on the proper use of antibiotics, issuing national recommendations for the treatment of urinary tract infections in order to standardize therapeutic regimens is strongly recommended. Effective control of these infections requires a global prevention strategy that implies close collaboration between epidemiologists, clinicians, bacteriologists, hygienists and the health care team.展开更多

The rise of resistance for modern antibiotic in infections treatment imposed us order alternatives. The study objective was to contribute in the knowledge of medicinal plants uses in urinary infections treatment in N’Djamena (Chad) in view for amelioration the traditional medicine in future. Methodology: The study was conducted in the city of N’Djamena in the Republic of Chad that interviewed 60 traditherapists on using 11 plants for urinary tract infections treatment. The methodology of this study consisted of the knowledge of medicinal plants that used by traditherapists, and the plants identification was done in the laboratory of IRED at Farcha. Results: A total of 60 traditherapists was interrogated on the plants used in the treatment of urinary tract infections among the population of N’Djamena. The majority of traditherapists interrogated in this study were male with the rate of 61.67% against female with the rate of 38.33%. The age range of traditherapists was between 20 to 80 years, 25 (41.67%) from the age range between 30 - 50 years and 35 (58.33%) in age range from 50 to 70 years. For the origin of their knowledge, the study showed that 72% of traditherapists inherited the knowledge from their family, while 15% inherited from the family and from training. The ethnic groups of the traditherapists were Sara (16%), Maraba (12%) and Massa (11%). According to the results, 18.33% were illiterates, 49% attended primary school and 33.34% the secondary school. Our study found that 11 species of plants belonging to 11 families were used in the treatment of urinary tract infection and the Ziziphus spina-christi was the most represented. According to traditherapists the Ziziphus spina-christi, Cassia obovata and Euphorbia hirta were the most frequent plants used in the urinary tract infections treatment. The parts of plants used in the treatment were leaves and bark, grained leaves and entire plants with the proportion of 50%, 16.67 and 15% respectively. Conclusion: This study revealed that the medicinal plants are variously used in the treatment of infection urinary tract in the city of N’Djamena.展开更多

This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.展开更多

Objective: To describe the epidemiological, clinical and biological profile of urinary tract infection in the internal medicine unit of the Fousseyni Daou hospital in Kayes. Methodology: It was a descriptive and cross-sectional study with retrospective data collection which took place from January 1 to December 31, 2020 at the Internal Medicine Unit of the Fousseyni Daou Hospital in Kayes. It covered all outpatients and hospitalized patients presenting with a urinary tract infection during the study period. Results: We identified 79 cases of urinary tract infection out of 145 requests for ECBU, that is a positivity rate of 53.10% and out of a total of 1883 admissions that is a hospital prevalence of 4.19%. The age groups of 36 to 45 years and 46 to 55 years were more represented in 28 cases (35.44%) and 25 cases (31.64%) with an average age of 45 years ± 10. The female sex was predominant, 42 cases (53.16%) with a sex ratio of 0.88. Housewives were more represented 28 cases (34.44%). The majority of patients resided in rural areas 49 cases (62.03%). The history was dominated by the following pathologies: hypertension 48.10%, diabetes 36.70% and gastropathy 30.37%. The main clinical manifestations were: Urinary burning 67 cases (84.81%), Dysuria 65 cases (82.27%), Pelvic pain 59 cases (74.68%), Fever 57 cases (72.15%). The epidemiological profile of the isolated strains was dominated by enterobacteriaceae, followed by gram-positive cocci and gram-negative bacilli. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli (45.56%), Klebsiella pneumoniae (11.39%), Pseudomonas aeruginosa (8.86%), Staphylococcus aureus (7.59%), Streptococcus sp (6.33%), Enterobacter cloacae (3.79%), Acinetobacter sp (3.79%). The study of the susceptibility and resistance profiles of the isolated strains showed significant sensitivity of enterobacteriaceae to colistin and resistance to amoxicillin and to the amoxicillin + clavulanic acid combination. Conclusion: Urinary tract infections are a major public health problem since they are responsible for significant morbidity and mortality and a high cost of care. Knowledge of the epidemiological-clinical and bacteriological profile of these infections is essential for efficient management.展开更多

ESBLs are bacteria with enzymes that make them resistant to many antibiotics, posing a significant health challenge. This study aims to determine the characteristics of ESBL-producing bacteria causing UTIs in expectant women. Methodology: A self-administered survey was carried out;300 expectant women were recruited using a random sampling method. A questionnaire was used to collect socio-demographic information. Urine samples were collected in sterile universal bottles and processed at the JKUAT Zoology laboratory. Urine samples were analyzed using urinalysis, microscopy, culture, and sensitivity testing. ESBL-producing bacteria were identified phenotypically using the double-disc synergy test (DDST) and genotyped for specific resistant genes using PCR. Results: UTI prevalence was 32.7% (98/300). UTI was significantly associated with the history of previous UTI (OR = 0.84, p = 0.02) and multigravida (OR = 0.14 p = 0.01). UTI was common in women aged between 28-37 years in their second trimester. Bacteria isolated were E. coli 57.1% (56/98), S. aureus 21.4% (21/98) K. pneumonia 11.2% (11/98) and Proteus spp 10.4% (10/98). Bacteria antibiotic resistance patterns were E. coli-tetracycline (91.1%), sulfamethoxazole (55.4%), cefotaxime (53.4%) and augmentin (53.4%). S. aureus-sulfamethozaxole (100%) and augmentin (71.4%), K. pneumoniae-sulfame-thoxazole (72.2%) cefotaxime (63.6%), chloramphenicol and tetracycline (54.5%). Proteus spp: tetracycline (100%), nitrofurantoin (90%), cefotaxime and chloramphenicol (50%). The proportion of ESBLs bacterial producers was 37.6% (29/77) and 44.8% (13/29) possessed ESBLs resistant genes;Bla CTX-M 53.8% (7/13), Bla SHV and Bla TEM 23.1% (3/13) each, Bla OXA (0%) was not detected. Conclusion: The study revealed a high proportion of ESBLs producing bacteria responsible for UTI in expectant women. ESBLs screening, routine culture and sensitivity testing will guide on proper management and empirical treatment of UTI patients thus reducing multi-drug resistance.展开更多

However, in resource-limited countries, accessibility to CBEU remains hindered by cost and availability. This study aims to assess the utility of the Urinary Dipstick Test (UDT) in diagnosing UTIs among hospitalized patients in the context of limited resources. Methods: A cross-sectional study was conducted from February to May 2019, encompassing hospitalized patients who underwent CBEU at the bacteriology unit of Sour? Sanou University Hospital. UDT and CBEU were concurrently performed, and UDT’s analytical and diagnostic performance was evaluated against CBEU, considered the gold standard. Results: A total of 274 CBEU requests were registered, involving 274 patients (159 males) with a mean age of 45.8 ± 21.3 years (ranging from 1 to 90 years). UTI was confirmed in 90 patients, yielding a frequency of 32.85%. The UTI bacteriological profile was dominated by Enterobacteriaceae (75.23%), primarily Escherichia coli (60.55%). Nitrite and Leukocytes were positive in 54 (19.8%) and 157 (53.6%) of the samples tested. Among patients with confirmed UTI, Nitrite, and Leukocytes were positive in 30 (33%) and 71 (79%) patients respectively. UDT demonstrated variable performance based on nitrite and leukocyte combination: Sensitivity (57%-82%), Specificity (7%-98%), Positive Predictive Value (PPV) (43%-57%), Negative Predictive Value (NPV) (43%-67%). UDT performed slightly better in women (NPV = 88%) and inpatients without urinary catheters (NPV = 75% and PPV = 80%). Conclusion: This study underscores UDT’s potential utility in excluding UTIs among women, younger patients, and inpatients without urinary catheters, albeit with limited confidence. The UDT emerges as a complementary tool for UTI screening, particularly in resource-limited settings.展开更多

Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3 % (11/72), and gray zone rate was 18.1 % (13/72). 31.9 % (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67 %. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.展开更多

In Mali, to our knowledge, no study concerning UTIs in the elderly has been conducted, hence the interest in this innovative work. <strong>Objectives:</strong> To determine the prevalence and clinical and paraclinical aspects of urinary tract infections in the elderly. <strong>Materials and Methods:</strong> This was a prospective descriptive and cross-sectional study from September 1, 2013 to August 31, 2014, <i>i.e. </i> duration of 12 months. All patients aged 65 years and over, hospitalized or ambulatory in the internal medicine department with a documented urinary tract infection were included. <strong>Results:</strong> We collected and examined 194 patients. The cytobacteriological study of urine (CBSU) was positive in 28 patients, <i>i.e. </i> a prevalence of 14.43%. The male sex represented 59.8% of the cases, the sex ratio was equal to 1.46. The age groups between 65 - 69 and 70 - 74 years were the most affected, respectively 28.57% and 39.28%. The main clinical signs were: asthenia, anorexia, dependence, fever, urinary burning, dysuria. Hospitalization was associated with urinary tract infection with P = 0.01. The group of enterobacteria were incriminated in 75% of cases. <i>Escherichia coli, Klebsiella pneumoniae</i> and <i>Pseudomonas aeruginosa</i> represented 39.28%, 14.28% and 10.71% of cases. Urinary tract infections were represented by pyelonephritis, acute prostatitis, orchi-epididymitis and simple cystitis. <strong>Conclusion:</strong> Urinary tract infection is frequent in the elderly, its clinical presentation is polymorphic and enterobacteria are the most incriminated group of bacteria.展开更多

In our country, most of the UTI patients visiting hospitals (OPD or IPD) are already on empirical antibiotics even before getting the sensitivity report in their hand. The purpose of this research was to examine the susceptibility patterns of commonly used antibiotics, particularly fosfomycin, against common uropathogens. Methodology: This was a prospective observational study conducted between January and March 2021 in four private tertiary hospitals in Dhaka, Bangladesh. All the urine samples referred to these four laboratories, obtained from patients of all ages and both genders, clinically diagnosed to have UTI, were included. Urine culture was performed by a semiquantitative method on blood agar media and MacConkey agar media. Following identification, antimicrobial sensitivity testing was performed using the modified Kirby Bauer disk diffusion method in accordance with CLSI standards. The data was put into Statistical Package for Social Sciences (SPSS) statistical software version 25 for the analysis. Results: A total of 5389 urine samples were received from four private hospitals in Dhaka over three months, and of these, 934 (17.33%) isolates were obtained from culture. About 95% of the isolates were gram-negative bacilli (GNBs). The most common isolate was Escherichia coli 615 (65.85%), followed by Klebsiella spp. 154 (16.49%), Pseudomonas spp. 64 (6.85%) and 51 (5.46%) isolates of Enterobacter. Among the gram-positive cocci, the most common were Enterococci fecalis 18 (1.93%) and Staphylococcus aureus 17 (1.82%). Of all the antibiotics tested, fosfomycin sensitivity was 98.4%, 88.88%, and 100% for Escherichia coli, Enterococci fecalis, and Staphylococcus aureus, respectively. All the isolates tested were susceptible to Meropenem (77% - 100%), Amoxiclav (78% - 100%) and Nitrofurantoin (45% - 94%). Sensitivity amongst all the uropathogens for ceftriaxone, ciprofloxacin, and cotrimoxazole was nearly 50% - 77%. Conclusion: The positivity of urinary isolates is 17.33%, with the most common pathogen being Escherichia coli. Common uropathogens show the highest in vitro susceptibility to fosfomycin. So, fosfomycin should be considered as a highly potent and promising alternative oral antibiotic treatment for UTI.展开更多

In addition, E. coli exhibits an increasing resistance to broad spectrum antimicrobial agents as well as the subsequent generations of these drugs. The genetic diversity and antibiotic resistance patterns of both clinical and environmental E. coli isolates were studied to predict the potential of transmission of organisms and genes for antibiotic resistance from three different major eco-habitats including the gut of iguanas’ fresh and marine waters and the human urinary tract. (GTG)<sub>5 </sub>and BOX-PCR extragenic DNA fingerprinting allowed for the tracking of the relatedness of four different ecotype groups. Both DNA fingerprinting methods targeted non-protein coding or exogenous palindromic DNA and demonstrated shared origin and intraspecies level of genomic diversity within the population of the studied bacteria. DNA fingerprinting based on BOX-PCR was less discriminating than the (GTG)<sub>5</sub>-PCR, and produced five major clades. BOX-PCR analysis indicated that 44% of the UTI E. coli isolates was comprised within a single clade, therefore it correlated better with ecotype distribution. The (GTG)<sub>5</sub> PCR based co-clustering analysis showed that the clinical isolates appeared to have a closer relationship to iguana E. coli isolates than to the fresh and marine water isolates. However, in accordance with the BOX PCR co-clustering analysis, the clinical isolates were most similar to the marine water isolates, followed by the freshwater and iguana E. coli isolates. Seventy two percent of antibiotic resistance patterns were shared by the UTI strains with E. coli isolated from freshwater, followed by iguana.展开更多

It is a common disease encountered in medical practice affecting people of all ages, from neonate to geriatric age group. These infections are on the increase for outpatients attending Primary Health Centres in Anambra State, Nigeria, therefore the need for this study. The prevalence rate of urinary tract infection, age distribution and influence of sex were determined. Susceptibility pattern of the infectious organisms to antimicrobial agent were examined. Clean-catch midstream urine samples were collected and examined. Out of 3000 urine samples examined, 528 bacterial isolates were recovered and characterized. These include: Escherichia coli (24.2%), Klebsiella spp. (18.2%), Staphylococcus aureus (18.2%), Proteus mirabilis (9.1%), Pseudomonas aeruginosa (9.1%), Enterococcus faecalis (9.1%), Citrobacter intermedius (6.1%) and Staphylococcus saprophyticus (6.1%). More females (52%) were infected than males (48%) and in both sexes, the highest incidence was found amongst the age group, 26 - 38 years. Gram negative rods had the highest incidence in both sexes. Among the towns in Anambra state, Umunya in southern province was observed to have the highest incidence rate of UTI. Susceptibility test of the bacterial isolates to antimicrobial agents showed that Staphylococcus aureus was sensitive to Cephalexin, Penicillin V, Erythromycin and Gentamycin while Pseudomonas aeruginosa was resistant to all the antibiotics. Escherichia coli and Klebsiella spp. were resistant to all the antibiotics except Gentamycin while Citrobacter intermedius was resistant only to Cephalexin and Erythromycin. This study provides the evidence of urinary tract infections amongst outpatients of primary health centres and the drugs for their control.展开更多
文摘Introduction: Enterobacteriaceae causing urinary tract infections (UTI) have developed resistance to the commonly used antibiotics due to emergence of Extended Spectrum Beta-Lactamases (ESBLs) and Carbapenamase producing Enterobactericeae which are a public health problem worldwide. This study aims to determine the prevalence and characterize ESBLs and carbapenamase producing Enterobactericeae. Method: A cross-sectional study was carried out in Gertrude’s Children’s Hospital, Nairobi. 238 urine samples were collected from patients with urinary symptoms attending the outpatient department within the period 2020-2021. The urine were examined macroscopically and microscopically. Identification and antimicrobial susceptibility testing were done using VITEK® 2 Compact system (BioMérieux). Double disc synergy test and modified hodge tests were done as confirmatory tests for ESBLs and Carbapenamase phenotypes respectively. Polymerase Chain Reaction was used for the detection of blaCTX-M, blaTEM, blaSHV, blaKPC and blaOXA-48 genes. Results: From the 238 children sampled the prevalence of UTI caused by Enterobactericeae was 22.3%. The Enterobacteriaceae species isolated were Escherichia coli (84.9%), Klebsiella pneumoniae (5.66%), Proteus mirabillis (5.66%), Enterobacter aerogenes (1.89%) and Morganella morganii (1.89%). The isolated species were resistant to ampicillin. Meropenem had the highest susceptibility. Only E. coli species had the ESBLs (26.4%) and carbapenamase (1.9%) phenotypes. 100% had BlaCTX-M while 50% had blaTEM resistant gene. There was a significant association (p Conclusion: Ampicillin resistance resulted to use of alternative drugs and Meropenem was the drug of choice where increased resistance to the recommended drugs was noted. Further research on resistant genes is recommended.
文摘Background: Urinary tract infection (UTI) is one of the most frequent bacterial infections in pediatrics. The aim of our work was to establish the epidemiological and bacteriological profile of UTIs in children and then to study the sensitivity of the bacterial strains isolated to antibiotics. Materials and methods: This is a retrospective descriptive study over 3 years (2019-2022), including all cytobacteriological examination of urine (CBEU), performed in children aged 3 months to 14 years, admitted and treated for UTI, in the pediatric emergency department of Mohamed VI University Hospital. Results: A total of 239 children were included in our study. The mean age was 26 months. The sex ratio was 1.08. Escherichia coli was the most isolated bacterial strain in 79% of samples. The tested strains showed a high level of sensitivity to susceptibility rate toward amikacin (91%) and ciprofloxacin (100%) and whereas the level of resistance was high to the most current recommended antibiotics, mainly beta-lactams. Management was based, in severe forms of pyelonephritis, dual antibiotic therapy based on Third-generation cephalosporins combined with gentamycin. Favorable outcome was noted in 94% of children. Conclusion: Awareness-raising on the proper use of antibiotics, issuing national recommendations for the treatment of urinary tract infections in order to standardize therapeutic regimens is strongly recommended. Effective control of these infections requires a global prevention strategy that implies close collaboration between epidemiologists, clinicians, bacteriologists, hygienists and the health care team.
文摘Introduction: Infection disease is a real publique health problem. The rise of resistance for modern antibiotic in infections treatment imposed us order alternatives. The study objective was to contribute in the knowledge of medicinal plants uses in urinary infections treatment in N’Djamena (Chad) in view for amelioration the traditional medicine in future. Methodology: The study was conducted in the city of N’Djamena in the Republic of Chad that interviewed 60 traditherapists on using 11 plants for urinary tract infections treatment. The methodology of this study consisted of the knowledge of medicinal plants that used by traditherapists, and the plants identification was done in the laboratory of IRED at Farcha. Results: A total of 60 traditherapists was interrogated on the plants used in the treatment of urinary tract infections among the population of N’Djamena. The majority of traditherapists interrogated in this study were male with the rate of 61.67% against female with the rate of 38.33%. The age range of traditherapists was between 20 to 80 years, 25 (41.67%) from the age range between 30 - 50 years and 35 (58.33%) in age range from 50 to 70 years. For the origin of their knowledge, the study showed that 72% of traditherapists inherited the knowledge from their family, while 15% inherited from the family and from training. The ethnic groups of the traditherapists were Sara (16%), Maraba (12%) and Massa (11%). According to the results, 18.33% were illiterates, 49% attended primary school and 33.34% the secondary school. Our study found that 11 species of plants belonging to 11 families were used in the treatment of urinary tract infection and the Ziziphus spina-christi was the most represented. According to traditherapists the Ziziphus spina-christi, Cassia obovata and Euphorbia hirta were the most frequent plants used in the urinary tract infections treatment. The parts of plants used in the treatment were leaves and bark, grained leaves and entire plants with the proportion of 50%, 16.67 and 15% respectively. Conclusion: This study revealed that the medicinal plants are variously used in the treatment of infection urinary tract in the city of N’Djamena.
文摘Background and Aims: Urinary tract infections (UTIs) are common among pregnant women and major predisposing factors for pyelonephritis linked to obstetrical complications including preterm labour and low infants’ birth weights. This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.

文摘Obiective:To investigate whether"Fuzheng Qingretonglin"decoction can reduce urinary tract damage caused by complex urinary tract infection caused by drug resistant Escherichia coli by regulating Nod-like receptor pyrin domain3 inflammasome,and to explore the feasibility of this decoction combined with levofloxacin in the treatment of complex urinary tract infection caused by drug resistant bacteria.Methods:SD rats were divided into five groups:sham group,model group,levofloxacin group(Lev group),levofloxacin+Fuzheng Qingre Tonglin decoction group(FZ+lev group),and Fuzheng Qingre Tonglin decoction group(FZQRTL group).After the experiment,urine was taken for bacterial culture to determine the urinary tract infection of rats in each group;HE staining was used to observe the pathological changes of kidney and bladder tissues in rats;The expression of NLRP3 in kidney and bladder tissues was detected by immunohistochemistry;The expression of IL-1βand IL-18 in serum of rats was detected by ELISA;The expressions of NLRP3,ASC and Caspase-1 were detected by Western blotting.Results:The positive rate of urine bacteria culture in the sham group was 0%,the positive rate of urine bacteria culture in the model group was 100%;and the positive rate of urine bacteria culture in the FZ+lev group was 37.50%,which was statistically different from that in the model group(P<0.05).A large number of inflammatory cells were observed in the kidney and bladder tissues of the model group by HE staining,while the number of inflammatory cells in the kidney and bladder tissues of the Lev group and FZQRTL group was significantly reduced compared with that of the model group.The FZ+lev group in the number and structure of inflammatory cells in kidney and bladder were similar to the sham group.The NLRP3 immunohistochemistry of kidney and bladder tissue in FZ+lev groups and FZQRTL groups was significantly different from that in model group(P<0.001).The levels of IL-1βand IL-18 in serum of Lev group,FZQRTL group and FZ+lev group were significantly decreased by ELISA compared with model group(P<0.001).The levels of IL-1βand IL-18 in the FZ+lev groups were significantly lower than in the Lev group and FZQRTL group,and the differences were statistically significant(P<0.05).The protein expressions of NLRP3,ASC and Caspase-1 in the Lev group,FZQRTL group and FZ+lev group were significantly lower than those in the model group(P<0.001).The protein expressions of NLRP3,ASC and Caspase-1 in the FZ+lev groups were significantly lower than in the Lev group and FZQRTL group,and the differences were statistically significant(P<0.05).Conclusions:"Fuzheng Qingretonglin"decoction may have a protective effect on the kidney and bladder of rats with complex urinary tract infection caused by drug-resistant Escherichia coli by inhibiting the activation of NLRP3 inflammatory bodies,and TCM combined with levofloxacin has a better therapeutic effect than TCM or levofloxacin alone.
文摘Introduction: Urinary tract infection is one of the most frequent public health problems in the world and concerns all ages. Objective: To describe the epidemiological, clinical and biological profile of urinary tract infection in the internal medicine unit of the Fousseyni Daou hospital in Kayes. Methodology: It was a descriptive and cross-sectional study with retrospective data collection which took place from January 1 to December 31, 2020 at the Internal Medicine Unit of the Fousseyni Daou Hospital in Kayes. It covered all outpatients and hospitalized patients presenting with a urinary tract infection during the study period. Results: We identified 79 cases of urinary tract infection out of 145 requests for ECBU, that is a positivity rate of 53.10% and out of a total of 1883 admissions that is a hospital prevalence of 4.19%. The age groups of 36 to 45 years and 46 to 55 years were more represented in 28 cases (35.44%) and 25 cases (31.64%) with an average age of 45 years ± 10. The female sex was predominant, 42 cases (53.16%) with a sex ratio of 0.88. Housewives were more represented 28 cases (34.44%). The majority of patients resided in rural areas 49 cases (62.03%). The history was dominated by the following pathologies: hypertension 48.10%, diabetes 36.70% and gastropathy 30.37%. The main clinical manifestations were: Urinary burning 67 cases (84.81%), Dysuria 65 cases (82.27%), Pelvic pain 59 cases (74.68%), Fever 57 cases (72.15%). The epidemiological profile of the isolated strains was dominated by enterobacteriaceae, followed by gram-positive cocci and gram-negative bacilli. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli (45.56%), Klebsiella pneumoniae (11.39%), Pseudomonas aeruginosa (8.86%), Staphylococcus aureus (7.59%), Streptococcus sp (6.33%), Enterobacter cloacae (3.79%), Acinetobacter sp (3.79%). The study of the susceptibility and resistance profiles of the isolated strains showed significant sensitivity of enterobacteriaceae to colistin and resistance to amoxicillin and to the amoxicillin + clavulanic acid combination. Conclusion: Urinary tract infections are a major public health problem since they are responsible for significant morbidity and mortality and a high cost of care. Knowledge of the epidemiological-clinical and bacteriological profile of these infections is essential for efficient management.
文摘Background: Urinary tract infection (UTI) is a bacterial infection affecting males and females but is more prevalent in expectant women. ESBLs are bacteria with enzymes that make them resistant to many antibiotics, posing a significant health challenge. This study aims to determine the characteristics of ESBL-producing bacteria causing UTIs in expectant women. Methodology: A self-administered survey was carried out;300 expectant women were recruited using a random sampling method. A questionnaire was used to collect socio-demographic information. Urine samples were collected in sterile universal bottles and processed at the JKUAT Zoology laboratory. Urine samples were analyzed using urinalysis, microscopy, culture, and sensitivity testing. ESBL-producing bacteria were identified phenotypically using the double-disc synergy test (DDST) and genotyped for specific resistant genes using PCR. Results: UTI prevalence was 32.7% (98/300). UTI was significantly associated with the history of previous UTI (OR = 0.84, p = 0.02) and multigravida (OR = 0.14 p = 0.01). UTI was common in women aged between 28-37 years in their second trimester. Bacteria isolated were E. coli 57.1% (56/98), S. aureus 21.4% (21/98) K. pneumonia 11.2% (11/98) and Proteus spp 10.4% (10/98). Bacteria antibiotic resistance patterns were E. coli-tetracycline (91.1%), sulfamethoxazole (55.4%), cefotaxime (53.4%) and augmentin (53.4%). S. aureus-sulfamethozaxole (100%) and augmentin (71.4%), K. pneumoniae-sulfame-thoxazole (72.2%) cefotaxime (63.6%), chloramphenicol and tetracycline (54.5%). Proteus spp: tetracycline (100%), nitrofurantoin (90%), cefotaxime and chloramphenicol (50%). The proportion of ESBLs bacterial producers was 37.6% (29/77) and 44.8% (13/29) possessed ESBLs resistant genes;Bla CTX-M 53.8% (7/13), Bla SHV and Bla TEM 23.1% (3/13) each, Bla OXA (0%) was not detected. Conclusion: The study revealed a high proportion of ESBLs producing bacteria responsible for UTI in expectant women. ESBLs screening, routine culture and sensitivity testing will guide on proper management and empirical treatment of UTI patients thus reducing multi-drug resistance.
文摘Background: Urinary Tract Infection (UTI), a prevalent bacterial infection in adults, heavily relies on cytobacteriological examination of urine (CBEU) for diagnosis. However, in resource-limited countries, accessibility to CBEU remains hindered by cost and availability. This study aims to assess the utility of the Urinary Dipstick Test (UDT) in diagnosing UTIs among hospitalized patients in the context of limited resources. Methods: A cross-sectional study was conducted from February to May 2019, encompassing hospitalized patients who underwent CBEU at the bacteriology unit of Sour? Sanou University Hospital. UDT and CBEU were concurrently performed, and UDT’s analytical and diagnostic performance was evaluated against CBEU, considered the gold standard. Results: A total of 274 CBEU requests were registered, involving 274 patients (159 males) with a mean age of 45.8 ± 21.3 years (ranging from 1 to 90 years). UTI was confirmed in 90 patients, yielding a frequency of 32.85%. The UTI bacteriological profile was dominated by Enterobacteriaceae (75.23%), primarily Escherichia coli (60.55%). Nitrite and Leukocytes were positive in 54 (19.8%) and 157 (53.6%) of the samples tested. Among patients with confirmed UTI, Nitrite, and Leukocytes were positive in 30 (33%) and 71 (79%) patients respectively. UDT demonstrated variable performance based on nitrite and leukocyte combination: Sensitivity (57%-82%), Specificity (7%-98%), Positive Predictive Value (PPV) (43%-57%), Negative Predictive Value (NPV) (43%-67%). UDT performed slightly better in women (NPV = 88%) and inpatients without urinary catheters (NPV = 75% and PPV = 80%). Conclusion: This study underscores UDT’s potential utility in excluding UTIs among women, younger patients, and inpatients without urinary catheters, albeit with limited confidence. The UDT emerges as a complementary tool for UTI screening, particularly in resource-limited settings.
文摘Objective:This paper expounds and analyzes the effect of cluster nursing in preventing urinary tract infection in postoperative patients with indwelling urinary catheter.Methods:A total of 400 postoperative patients with indwelling urinary catheter,treated in Yancheng No.1 People’s Hospital in recent two years,were recruited as research subjects.The patients were equally divided into group A and group B,with 200 patients in each group,and all received routine anti-infectives.The patients in group A(200 cases)received routine nursing.On the basis of group A,cluster nursing was implemented for patients in group B(200 cases).Results:The indwelling time of urinary catheter,the disappearance time of bladder irritation symptoms,and the probability of urinary tract infection were compared between both groups,which showed that the nursing effect of group B was better than that of group A(P<0.05).Conclusion:The implementation of cluster nursing in postoperative patients with indwelling urinary catheter can improve the deficiency of routine nursing,consolidate the treatment effect,and reduce the complication rate of urinary tract infection.
文摘Summary: In order to study the association between lower urinary tract infection and cystitis glandularis (CG), 120 cases of CG were diagnosed by cystoscopic biopsy in the suspicious foci of the bladder. Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3 % (11/72), and gray zone rate was 18.1 % (13/72). 31.9 % (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67 %. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.

文摘Objective:Urinary tract infection(UTI)is a common cause of morbidity and hospitalisation in the population worldwide.Upper UTI is indolent and causes subclinical acute kidney injury(AKI)resulting in preventable cause of scarring of renal parenchyma.We explored urinary and serum levels of kidney injury molecule-1(KIM-1),haematological parameters and quantitative urine microscopy parameters to predict kidney injury.Methods:Neutrophilelymphocyte ratio(NLR)is obtained by dividing absolute neutrophil count with absolute lymphocyte count.Quantitative urine sediment microscopy was performed and correlated with clinical,biochemical and haematological findings to predict AKI in patients with UTI.Quantitative ELISA was performed for serum and urine levels of KIM-1.Seventy two adult patients with UTI were enrolled,45 of whom had AKI while 27 were in the non-AKI group.Results:NLR(p=0.005)and renal tubular epithelial cell-granular cast score in quantitative urine microscopy(p=0.008)are strong predictors of AKI in patients with UTI while rest of quantitative urine microscopy parameters and serum and urinary levels of KIM-1 molecule were not found to be useful in prediction of AKI.Conclusion:NLR in haemogram is a novel and useful biomarker for predicting AKI in patients with UTI.
文摘<strong>Introduction:</strong> Urinary tract infections (UTI) are frequent and of polymorphous clinical symptomatology in elderly subjects both in and out of hospital. In Mali, to our knowledge, no study concerning UTIs in the elderly has been conducted, hence the interest in this innovative work. <strong>Objectives:</strong> To determine the prevalence and clinical and paraclinical aspects of urinary tract infections in the elderly. <strong>Materials and Methods:</strong> This was a prospective descriptive and cross-sectional study from September 1, 2013 to August 31, 2014, <i>i.e. </i> duration of 12 months. All patients aged 65 years and over, hospitalized or ambulatory in the internal medicine department with a documented urinary tract infection were included. <strong>Results:</strong> We collected and examined 194 patients. The cytobacteriological study of urine (CBSU) was positive in 28 patients, <i>i.e. </i> a prevalence of 14.43%. The male sex represented 59.8% of the cases, the sex ratio was equal to 1.46. The age groups between 65 - 69 and 70 - 74 years were the most affected, respectively 28.57% and 39.28%. The main clinical signs were: asthenia, anorexia, dependence, fever, urinary burning, dysuria. Hospitalization was associated with urinary tract infection with P = 0.01. The group of enterobacteria were incriminated in 75% of cases. <i>Escherichia coli, Klebsiella pneumoniae</i> and <i>Pseudomonas aeruginosa</i> represented 39.28%, 14.28% and 10.71% of cases. Urinary tract infections were represented by pyelonephritis, acute prostatitis, orchi-epididymitis and simple cystitis. <strong>Conclusion:</strong> Urinary tract infection is frequent in the elderly, its clinical presentation is polymorphic and enterobacteria are the most incriminated group of bacteria.

文摘Urinary tract infection(UTI) is one of the most commonchildhood infections.Permanent renal cortical scarring may occur in affected children,especially with recurrent UTIs,leading to long-term complications such as hypertension and chronic renal failure.To prevent such damage,several interventions to prevent UTI recurrences have been tried.The most established and accepted prevention at present is low dose long-term antibiotic prophylaxis.However it has a risk of break through infections,adverse drug reactions and also the risk of developing antibiotic resistance.The search is therefore on-going to find a safer,effective and acceptable alternative.A recent meta-analysis did not support routine circumcision for normal boys with no risk factors.Vaccinium Macrocarpon(cranberry),commonly used against UTI in adult women,is also effective in reducing the number of recurrences and related antimicrobial use in children.Sodium pentosanpolysulfate,which prevents bacterial adherence to the uroepithelial cells in animal models,has shown conflicting results in human trials.When combined with antibiotic,Lactobacillus acidophilus(LA-5) and Bifidobacterium,by blocking the in vitro attachment of uropathogenic bacteria to uroepithelial cells,significantly reduce in the incidence of febrile UTIs.Deliberate colonization of the human urinary tract of patients with recurrent UTI with Escherichia-coli(E.coli) 83972 has resulted in subjective benefit and less UTI requiring treatment.The non-pathogenic E.coli isolate NU14 DeltawaaL is a candidate to develop liveattenuated vaccine for the treatment and prevention of acute and recurrent UTI.Diagnosing and treating dysfunctional elimination syndromes decrease the incidence of recurrent UTI.A meta-analysis found the lack of robust prospective randomized controlled trials limited the strength of the established guidelines for surgical management of vesicoureteral reflux.In conclusion,several interventions,other than antibiotic prophylaxis,for the prevention of recurrent UTI have been tried and,although showing some promise,they do not provide so far a definitive effective answer.Finding suitable alternatives still requires further high quality research of those seemingly promising interventions.
文摘Background: Among the common morbid causes that are prevalent among all age groups, urinary tract infections top the list. In our country, most of the UTI patients visiting hospitals (OPD or IPD) are already on empirical antibiotics even before getting the sensitivity report in their hand. The purpose of this research was to examine the susceptibility patterns of commonly used antibiotics, particularly fosfomycin, against common uropathogens. Methodology: This was a prospective observational study conducted between January and March 2021 in four private tertiary hospitals in Dhaka, Bangladesh. All the urine samples referred to these four laboratories, obtained from patients of all ages and both genders, clinically diagnosed to have UTI, were included. Urine culture was performed by a semiquantitative method on blood agar media and MacConkey agar media. Following identification, antimicrobial sensitivity testing was performed using the modified Kirby Bauer disk diffusion method in accordance with CLSI standards. The data was put into Statistical Package for Social Sciences (SPSS) statistical software version 25 for the analysis. Results: A total of 5389 urine samples were received from four private hospitals in Dhaka over three months, and of these, 934 (17.33%) isolates were obtained from culture. About 95% of the isolates were gram-negative bacilli (GNBs). The most common isolate was Escherichia coli 615 (65.85%), followed by Klebsiella spp. 154 (16.49%), Pseudomonas spp. 64 (6.85%) and 51 (5.46%) isolates of Enterobacter. Among the gram-positive cocci, the most common were Enterococci fecalis 18 (1.93%) and Staphylococcus aureus 17 (1.82%). Of all the antibiotics tested, fosfomycin sensitivity was 98.4%, 88.88%, and 100% for Escherichia coli, Enterococci fecalis, and Staphylococcus aureus, respectively. All the isolates tested were susceptible to Meropenem (77% - 100%), Amoxiclav (78% - 100%) and Nitrofurantoin (45% - 94%). Sensitivity amongst all the uropathogens for ceftriaxone, ciprofloxacin, and cotrimoxazole was nearly 50% - 77%. Conclusion: The positivity of urinary isolates is 17.33%, with the most common pathogen being Escherichia coli. Common uropathogens show the highest in vitro susceptibility to fosfomycin. So, fosfomycin should be considered as a highly potent and promising alternative oral antibiotic treatment for UTI.
文摘Urinary Tract Infections (UTIs) are among one of the most common infections in women, with uropathogenic E. coli (UPEC) being involved in 80% of cases. In addition, E. coli exhibits an increasing resistance to broad spectrum antimicrobial agents as well as the subsequent generations of these drugs. The genetic diversity and antibiotic resistance patterns of both clinical and environmental E. coli isolates were studied to predict the potential of transmission of organisms and genes for antibiotic resistance from three different major eco-habitats including the gut of iguanas’ fresh and marine waters and the human urinary tract. (GTG)<sub>5 </sub>and BOX-PCR extragenic DNA fingerprinting allowed for the tracking of the relatedness of four different ecotype groups. Both DNA fingerprinting methods targeted non-protein coding or exogenous palindromic DNA and demonstrated shared origin and intraspecies level of genomic diversity within the population of the studied bacteria. DNA fingerprinting based on BOX-PCR was less discriminating than the (GTG)<sub>5</sub>-PCR, and produced five major clades. BOX-PCR analysis indicated that 44% of the UTI E. coli isolates was comprised within a single clade, therefore it correlated better with ecotype distribution. The (GTG)<sub>5</sub> PCR based co-clustering analysis showed that the clinical isolates appeared to have a closer relationship to iguana E. coli isolates than to the fresh and marine water isolates. However, in accordance with the BOX PCR co-clustering analysis, the clinical isolates were most similar to the marine water isolates, followed by the freshwater and iguana E. coli isolates. Seventy two percent of antibiotic resistance patterns were shared by the UTI strains with E. coli isolated from freshwater, followed by iguana.
文摘Urinary tract infections (UTIs) are one of the most prevalent extra-intestinal bacterial infections. It is a common disease encountered in medical practice affecting people of all ages, from neonate to geriatric age group. These infections are on the increase for outpatients attending Primary Health Centres in Anambra State, Nigeria, therefore the need for this study. The prevalence rate of urinary tract infection, age distribution and influence of sex were determined. Susceptibility pattern of the infectious organisms to antimicrobial agent were examined. Clean-catch midstream urine samples were collected and examined. Out of 3000 urine samples examined, 528 bacterial isolates were recovered and characterized. These include: Escherichia coli (24.2%), Klebsiella spp. (18.2%), Staphylococcus aureus (18.2%), Proteus mirabilis (9.1%), Pseudomonas aeruginosa (9.1%), Enterococcus faecalis (9.1%), Citrobacter intermedius (6.1%) and Staphylococcus saprophyticus (6.1%). More females (52%) were infected than males (48%) and in both sexes, the highest incidence was found amongst the age group, 26 - 38 years. Gram negative rods had the highest incidence in both sexes. Among the towns in Anambra state, Umunya in southern province was observed to have the highest incidence rate of UTI. Susceptibility test of the bacterial isolates to antimicrobial agents showed that Staphylococcus aureus was sensitive to Cephalexin, Penicillin V, Erythromycin and Gentamycin while Pseudomonas aeruginosa was resistant to all the antibiotics. Escherichia coli and Klebsiella spp. were resistant to all the antibiotics except Gentamycin while Citrobacter intermedius was resistant only to Cephalexin and Erythromycin. This study provides the evidence of urinary tract infections amongst outpatients of primary health centres and the drugs for their control.
