RESUMO

The management of urinary tract infection (UTI) in infants and children has changed significantly over the past few decades based on scientific evidence that questioned the efficacy of strategies used to prevent kidney injury and subsequent progression to chronic kidney disease, which is very unlikely in most paediatric cases. However, there is still substantial heterogeneity in its management and uncertainty regarding the diagnosis, indication of imaging tests, treatment or follow-up in these patients. The Spanish clinical practice guideline has been updated through the review of the literature published since 2009 and a rigorous evaluation of current clinical practice aspects, taking into account the evidence on the benefits of each intervention in addition to its risks and drawbacks to attempt to provide more precise recommendations.

RESUMO

Las infecciones del tracto urinario se encuentran entre las enfermedades infecciosas más comunes en todo el mundo, Los pacientes con diabetes mellitus suelen presentar una función inmune deteriorada y enfermedades infecciosas agravadas. La infección del tracto urinario es una de las principales complicaciones de la diabetes mellitus, aumenta la susceptibilidad a las infecciones, en parte debido a la alteración de la función de los granulocitos, un control glucémico inadecuado e hiperglucemia crónica que condiciona la presencia de microangiopatía diabética.


Urinary tract infections are among the most common infectious diseases worldwide. Patients with diabetes mellitus sometimes presented with impaired immune function and aggravated infectious diseases. Urinary tract infection is one of the main complications of diabetes mellitus; it increases susceptibility to infections, partly due to altered granulocyte function, inadequate glycemic control and chronic hyperglycemia that conditions the presence of diabetic microangiopathy.

RESUMO

BACKGROUND: Urinary tract infection (UTI) is infants' most common serious bacterial infection. This study aimed to investigate the reliability of urianalysis (UA) to predict UTI, to specify the colony forming units (CFU)/ml threshold for diagnosis, and to identify variables that help suspect bacteremia in infants under 3 months with UTI. METHODS: We reviewed clinical records of children under 3 months hospitalized for a fever without source and recorded age, sex, days of fever pre-consultation, temperature and severity at admission, discharge diagnoses, laboratory tests, and treatments. According to the discharge diagnosis, we divided them into UTIs (-) and (+) with or without bacteremia. RESULTS: A total of 467 infants were admitted: 334 with UTI and 133 without UTI. In UTIs (+), the pyuria had a sensitivity of 95.8% and bacteria (+) 88.3%; specificity was high, especially for nitrites (96.2%) and bacteria (+) (92.5%). Positive predictive value (PPV) for nitrites was 95.9%, for bacteria 96.7%, and oyuria 92.5%. Escherichia coli was present in 83.8% of urine and 87% of blood cultures. UTIs with bacteremia had inflammatory urinalysis, urine culture > 100,000 CFU/ml, and higher percentage of C reactive protein (CRP) > 50 mg (p= 0.002); 94.6% of the urine culture had > 50,000 CFU. CONCLUSIONS: The pyuria and bacteria (+) in urine obtained by catheterization predict UTI. The cut-off point for diagnosis was ≥ 50,000 CFU/ml. No variables to suspect bacteremia were identified in this study.


INTRODUCCIÓN: La infección del tracto urinario (ITU) es una infección bacteriana grave frecuente en lactantes. El objetivo de este trabajo fue investigar la fiabilidad del análisis de orina (AO) para predecirla, precisar el umbral de unidades formadoras de colonias (UFC)/ml para el diagnóstico y buscar variables que ayuden a sospechar de bacteriemia en lactantes menores de 3 meses con ITU. MÉTODOS: Se revisaron fichas clínicas de lactantes menores de 3 meses hospitalizados por fiebre sin foco evidente, registrando edad, sexo, días de fiebre preconsulta, temperatura y gravedad al ingreso, diagnósticos de egreso, exámenes de laboratorio y tratamientos. Según diagnóstico de egreso, se separaron en ITU (-) y (+), con o sin bacteriemia. RESULTADOS: Ingresaron 467 lactantes: 334 con ITU y 133 sin ITU. En ITU (+), la sensibilidad de la piuria fue de 95.8% y bacterias (+) 88.3%; la especificidad fue alta para nitritos (96.2%) y bacterias (+) (92.5%). El valor predictivo positivo (VPP) fue de 95.9% para nitritos, 96.7% para bacterias y 92.5% para piuria. Escherichia coli se encontró en el 83.8% de los urocultivos (UC) (+) y en el 87% de los hemocultivos (+). Las ITU con bacteriemia presentaron elementos inflamatorios, UC con ≥ 100,000 UFC/ml y mayor porcentaje de proteína C reactiva (PCR) > 50 mg/l (p= 0.002); el 94.6% de los UC (+) tuvo ≥ 50,000 UFC/ml. CONCLUSIONES: La piuria y bacterias (+) en el AO son excelentes para pronosticar ITU en orina obtenida con sonda vesical y el punto de corte para el diagnóstico debe ser ≥ 50,000 UFC/ml. No encontramos señales que ayudaran a sospechar ITU con bacteriemia.

RESUMO

INTRODUCCIÓN: Fosfomicina es un antimicrobiano de amplio espectro utilizado para el tratamiento de las infecciones urinarias bajas; tiene actividad sobre bacilos gramnegativos y cocos grampositivos, así también sobre microorganismos multirresistentes, además de ofrecer una alternativa terapéutica de administración vía oral en dosis única, alcanzando una efectividad de 90%. OBJETIVO: Conocer la sensibilidad in vitro de Escherichia coli frente a fosfomicina, en infecciones urinarias provenientes de personas con discapacidad. MATERIAL Y MÉTODO: Estudio observacional, descriptivo, prospectivo, en el que se incluyó un total de 273 muestras de urocultivo, de pacientes de ambos sexos que acudieron a SENADIS, y que en el momento de la consulta presentaban síntomas de infección del tracto urinario, por lo que se les solicitó el análisis de orina simple y cultivo. De las muestras procesadas en el laboratorio de microbiología, que fueron positivas con crecimiento bacteriano significativo, se procedió a la identificación bacteriana y a la realización del antibiograma según las recomendaciones de CLSI. RESULTADOS: De estas 273 muestras, 91 fueron positivas para diferentes uropatógenos, 62/91 (68%) resultaron ser E. coli. De estas cepas de E. coli, 59/62 (95%) mostraron sensibilidad in vitro a fosfomicina. Comentario: Aunque el número de muestra obtenido es pequeño y no extrapolable ampliamente, pretendemos extender el trabajo por un tiempo más para compararlo más adelante. CONCLUSIONES: Se observa que fosfomicina presenta buena actividad in vitro frente a cepas de E. coli aisladas de urocultivo, pudiendo representar una buena alternativa terapéutica a ser utilizada en la población en estudio.


BACKGROUND: Fosfomycin is a broad-spectrum antibiotic used for the treatment of lower urinary tract infections, it is active against gramnegative bacilli and grampositive cocci, as well as against multi-resistant microorganism, in addition to offering a therapeutic alternative for oral administration in a single dose, reaching an effectiveness of 90%. AIM: To study the susceptibility of Escherichia coli to fosfomycin in urinary tract infections, of isolated strains obtained from patients with disabilities. METHODS: It is an observational, descriptive, prospective study in which a total of 273 urine culture samples of patients of both sexes who attended the SENADIS were included, and who at the time of the consultation presented symptoms of urinary tract infection. The urine positive cultures with significant bacterial growth were performed to determine its bacterial identification and the antibiogram according to CLSI recommendations. RESULTS: Of these 273 samples, 91 samples were positive for different uropathogens, with 62/91 (68%) being positive for E. coli. Of these E. coli strains, 59/62 (95%) showed in vitro susceptibility to fosfomycin. Comment: Although the number of samples obtained is small and it cannot be extrapolated, we pretend to extend the work for a while longer to be able to compare it later. CONCLUSION: Fosfomycin has good activity in vitro against E. coli isolated from urine culture in our institution, representing a good alternative to be used in our study population

RESUMO

Objetivos: Generar recomendaciones informadas en la evidencia, a través de un consenso formal, orientadas al tratamiento de la infección de vías urinarias altas durante la gestación. Materiales y métodos: En el grupo desarrollador participaron expertos temáticos en microbiología, salud pública, medicina interna, infectología, obstetricia, medicina materno-fetal e infectología ginecobstétrica. También hicieron parte profesionales con entrenamiento en epidemiología clínica, búsqueda sistemática de la información, representantes de la Secretaría de Salud y la Asociación Bogotana de Obstetricia y Ginecología. Los participantes presentaron sus conflictos de interés. A partir de una pregunta clínica se realizó la graduación de los desenlaces y una búsqueda sistemática que abarcó las bases de datos Medline vía PubMed, Embase, Lilacs, Bireme. La pesquisa se amplió a repositorios institucionales y reportes de vigilancia de resistencia antimicrobiana, sin restricción de idioma o fecha, la búsqueda se actualizó el 1 de octubre de 2022. Se utilizó la metodología GRADE (Grading of Recommendations Assessment, Development and Evaluation) para valorar la calidad de la evidencia y establecer la fuerza de las recomendaciones. Finalmente, se utilizó la metodología RAND/ UCLA (Research and Development/University of California Los Angeles) para el consenso formal. Este documento fue revisado por pares académicos previo a su publicación. Resultados: El consenso formuló las siguientes recomendaciones. Recomendación 1. Se sugiere que el manejo inicial de la gestante con infección de vías urinarias (IVU) altas se realice de forma intrahospitalaria. Recomendación 2. Como primera opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas se realice con el uso de cefalosporinas de segunda generación con el fin de mejorar la tasa de cura clínica y microbiológica. Recomendación 3. Como segunda opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas en el segundo y tercer trimestre se realice con aminoglucósidos dado su balance riesgo-beneficio. Recomendación 4. Como tercera opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas se realice con el uso de cefalosporinas de tercera generación, debido a que el riesgo de inducción de resistencia microbiana es alto con este grupo de antibióticos. Recomendación 5. Como primera opción, en mujeres gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera o cuarta generación se sugiere el uso de carbapenémicos. Recomendación 6. Como segunda opción, en gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera generación se sugiere el uso de aminoglucósidos o cefalosporinas de cuarta generación teniendo en cuenta el riesgo-beneficio. Recomendación 7. Como tercera opción, en gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera o cuarta generación se sugiere el uso de piperacilina/tazobactam. Recomendación 8. En gestantes con IVU altas se recomienda realizar urocultivo previo al inicio de tratamiento antimicrobiano empírico. Recomendación 9. En gestantes con IVU altas, cuando el urocultivo reporte resistencia al antimicrobiano iniciado de forma empírica, se sugiere modificar la terapia guiada por los resultados del antibiograma. Recomendación 10. En la gestante hospitalizada por IVU altas se sugiere realizar el cambio de terapia antimicrobiana a vía oral cuando la paciente tenga, al menos, 48 horas de modulación de respuesta inflamatoria sistémica y de los signos clínicos de infección, así como adecuada tolerancia a vía oral. Recomendación 11. En gestantes con IVU altas, sin complicaciones secundarias a la infección primaria, se recomienda que la terapia antibiótica se administre de 7 a 10 días. Conclusiones: se espera que este consenso colombiano de IVU altas reduzca la variabilidad en la práctica clínica. Se recomienda a los grupos de investigación en medicina materno fetal e infectología evaluar la implementación y efectividad de las recomendaciones emitidas.


Objectives: To generate evidence-based recommendations through formal consensus regarding the treatment of upper urinary tract infections during gestation. Materials and methods: Experts in microbiology, public health, internal medicine, infectious diseases, obstetrics, maternal fetal medicine and obstetric and gynecological infections participated in the consensus development group. The group also included professionals with training in clinical epidemiology, systematic data search, and representatives from the Health Secretariat and the Bogota Obstetrics and Gynecology Association. The participants disclosed their conf licts of interest. Starting with a clinical question, outcomes were graded and a systematic search was conducted in the Medline via PubMed, Embase, Lilacs, and Bireme databases. The search was expanded to include institutional repositories and antimicrobial resistance surveillance systems, with no language or date restrictions. The search was updated on October 1, 2022. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to assess the quality of the evidence and determine the strength of the recommendations. Finally, the RAND/UCLA (Research and Development/University of California Los Angeles) methodology was applied for the formal consensus. This document was reviewed by academic peers before publication. Results: The following are the consensus recommendations. Recommendation 1. The initial management of pregnant women with upper urinary tract infections (UTIs) should be approached in a hospital setting. Recommendation 2. The use of second generation cephalosporins is the suggested first option for empirical antimicrobial management in pregnant women with upper UTI in order to improve the rates of clinical and microbiological cure. Recommendation 3. Because of the risk-benefit balance, the use of aminoglycosides is suggested as a second option for empirical antimicrobial treatment in pregnant women presenting with upper UTIs in the second and third trimester. Recommendation 4. The use of third-generation cephalosporins is suggested as the third option for empirical antimicrobial treatment in pregnant women with upper UTIs given that the risk of inducing microbial resistance is high with this group of antibiotics. Recommendation 5. The use of carbapenems is suggested as a first option in pregnant women with upper UTIs and a history of infections caused by microorganisms with resistance to third or fourth-generation cephalosporins. Recommendation 6. The use of aminoglycosides or fourth-generation cephalosporins is suggested as a second option in pregnant women with upper UTIs and a history of infection caused by microorganisms with resistance to third-generation cephalosporins, taking risk-benefit into account. Recommendation 7. The use of piperacillin/tazobactam is suggested as a third option in pregnant women with upper UTIs and a history of infection caused by microorganisms with resistance to third or fourth-generation cephalosporins. Recommendation 8. Getting a urine culture is recommended in pregnant women with upper UTIs before initiating empirical antimicrobial treatment. Recommendation 9. In pregnant women with upper UTIs, it is suggested to modify therapy in accordance with the results of the sensitivity test when the culture report shows resistance to the antimicrobial agent initiated empirically. Recommendation 10. In pregnant women hospitalized due to upper UTIs, it is suggested to switch to oral antimicrobial therapy after at least 48 hours of modulation of the systemic inflammatory response and the clinical signs of infection, and when tolerance to oral intake is adequate. Recommendation 11. In pregnant women with upper UTIs with no complications secondary to the primary infection, it is recommended to administer antibiotic therapy for a period of 7 to 10 days. Conclusions: It is expected that with this Colombian upper UTI consensus variability in clinical practice will be reduced. It is recommended that groups doing research in maternal fetal medicine assess the implementation and effectiveness of these recommendations.

RESUMO

Uncomplicated urinary tract infection (UTI) is the most common bacterial infection in women. Since 1948, the relationship between urinary pH and antibiotics (ABs) has been established. We aimed to search for the best urinary pH for each family of antibiotics and to assess whether pH changes bacterial susceptibility to them. We included in vitro research and in vivo studies including one or more bacterial species and tested the effect of one or more ABs at different pH values. We also included randomized controlled clinical trials (RCTs) in uncomplicated UTI (EAU guidelines 2019 definition), choosing the ABs based on urinary pH or using an antibiotic plus urinary pH modifiers (L-methionine, vitamin C…) vs. an antibiotic and a placebo. Quadas-2 tool was used as a quality assessment of the studies and PRISMA set of items for systematic reviews. Two authors independently screened and evaluated the papers, while two additional authors individually repeated the search. A fifth researcher acted as an arbiter, and another author collaborated as a hospital pharmaceutical consultant. Alkaline-friendly antibiotics are most fluoroquinolones, aminoglycosides, trimethoprim. Acidic-friendly antibiotics are fosfomycin, tetracycline, nitrofurantoin and some ß-lactams. We suggest performing urine cultures with antibiogram tests, in both acidic and alkaline media, to define the bacterial susceptibility profile. There is insufficient in vivo evidence to support whether choosing an antibiotic based on a patient's urinary pH or adding urinary pH modifiers will lead to a higher cure rate.

RESUMO

INTRODUCTION: To evaluate the impact of external urine collection devices (UCD) on contamination of urine samples in women with symptoms of urinary tract infection. METHODS: This review was conducted according to the Systematic Reviews of Diagnostic Test Accuracy guidelines (PROSPERO CRD42021241758). PubMed was searched for paired sample studies and controlled trials. Studies comparing UCDs with non-invasive urine collection procedures were considered. RESULTS: Only two studies were found. Neither of the two studies found any difference regarding contamination between specimens collected with the UCDs compared and non-invasive techniques. In the largest study, including 1264 symptomatic women, 18.8% of those allocated to UCDs failed to collect urine samples successfully. CONCLUSIONS: More studies involving women with symptoms of urinary tract infection are needed to produce more robust data on the impact of these devices on urine contamination rates.

RESUMO

Abstract Objective: to determine the association of prior antibiotic use, prior hospitalizations, prior urinary tract infections, age, sex and comorbidities in adult patients hospitalized with urinary tract infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli. Materials and methods: a case-control study carried out in the hospital setting of private clinics in Lima. Thirty cases and 30 controls were included, with cases defined as hospitalized patients with an ESBL-producing E. coli urinary tract infection diagnosed by urine culture, and controls defined as hospitalized patients without ESBL-producing E. coli infection. Data were taken from incident cases. A bivariate analysis was performed followed by multivariate logistic regression using the significant variables from the bivariate analysis. Results: the associated factors were: prior antibiotic use OR: 261 (22.5-11,017.4), prior hospitalization OR: 4.6 (1.39-16.1), and prior urinary tract infection OR: 36 (6.9-227.2). After adjusting for potential confounding factors using logistic regression, the main statistically significant associated factor was prior antibiotic use, OR: 97.7 (8.4-1,128.3, p<0.000). Conclusion: evidence was found that prior antibiotic use is a risk factor significantly associated with ESBL E. coli urinary tract infections. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2131).


Resumen Objetivo: establecer la asociación del uso previo de antibióticos, hospitalizaciones previas, infección urinaria previa, edad, sexo y comorbilidades en pacientes adultos hospitalizados con infección urinaria por Escherichia coli productora de beta lactamasas de espectro extendido (BLEE). Material y métodos: estudio caso control, realizado en clínicas privadas de Lima en ámbito hospitalario. Se incluyeron 30 casos y 30 controles, definiéndose como caso al paciente hospitalizado que cuente con diagnóstico de infección urinaria por urocultivo de E. coli productora de BLEE y como control al paciente hospitalizado sin infección por E. coli BLEE. Se recolectó la información de casos incidentes. Se realizó un análisis bivariado y regresión logística multivariable con las variables que fueron significativas en el análisis bivariado. Resultados: los factores asociados fueron: uso previo de antibióticos OR: 261 (22.5-11017.4), hospitalización previa OR: 4.6 (1.39-16.1), infección urinaria previa OR: 36 (6.9-227.2). Al ajustar por variables potencialmente confusoras mediante regresión logística, se observó que el principal factor asociado con significación estadística fue el uso previo de antibióticos, OR: 97.7 (8.4-1128.3, p<0.000). Conclusión: se encontró evidencia de que el uso previo de antibióticos es un factor de riesgo asociado significativamente a infección urinaria por E. coli BLEE. (Acta Med Colomb 2022; 47.

RESUMO

Los tumores de ovario son los trastornos ginecológicos más comunes. Los tumores de ovario son el tercer tumor más común en las mujeres. Los tumores de ovario a veces son asintomáticos y tienen síntomas no específicos, lo que hace que la mayoría de los casos sean difíciles de detectar temprano. El objetivo de este estudio fue investigar las características genitourinarias del tumor ovárico en un estudio hospitalario. Se realizó un estudio observacional en Bagdad, Iraq, entre septiembre de 2018 y febrero de 2021. Las mujeres diagnosticadas con tumores ovarios a los 18 años de edad o más. Un total de cincuenta mujeres que se inscribieron en nuestro hospital. Datos clínicos y patológicos recopilados y analizados. Los datos sobre comorbilidades y resultados fueron aprobados y diagnosticados por un equipo completo de médicos ginecológicos y urológicos multidisciplinarios. La incidencia general de tumores ováricos fue 70% maligna y 30% benigna. El estudio mostró que la mayor parte del grupo de edad de tumores ováricos era superior a 55 años (62%). La mitad de los pacientes eran nuliparidades. El nivel educativo era principalmente de bajo nivel en analfabeto (20%), primario (24%), secundario (36%) en comparación con el alto nivel. Las mujeres usaron anticoncepción en 52%. La historia familiar informó en el 18% de las mujeres. El tipo histopatológico más común era el carcinoma seroso ovárico 15 (30%). Las etapas regionales eran comunes en el 50% de los pacientes. Tumores de bajo grado en 32%, intermedio en 36%y alto en 32%. Casi, el 80% de las mujeres se sometieron a TAH. Alrededor del 60% de los pacientes recibieron quimioterapia. Los resultados de salud genitourinaria adversos a largo plazo incluyeron nefritis (6%), insuficiencia renal aguda (16%), enfermedad renal crónica (18%), infección urinaria (38%), cálculo (16%), hidronefrosis (20%), Obstrucción de la vejiga (2%), estenosis ureteral (12%), retención de orina (8%), incontinencia de orina (12%), hematuria (22%), PID (14%), adhesión de órganos (8%), cervicitis (2 %), Endometriosis (2%), quiste (6%), trastornos menstruales (24%), infertilidad (2%) y dolor menopáusica (32%). En conclusión, el cáncer de ovario representa el tercer tipo de cáncer ginecológico más común. Era más común en mujeres mayores de cinco décadas. El tipo histopatológico más común es el carcinoma seroso ovárico. Observamos que los sobrevivientes de cáncer de ovario experimentaron mayores riesgos de varias enfermedades genitourinarias. Comprender los escenarios de la morbilidad múltiple para los tumores ováricos es de vital importancia para mejorar la atención clínica después del diagnóstico.


Ovarian tumors are the most common gynecological disorders. Ovarian tumors are the third most common tumor in women. Ovarian tumors are sometimes asymptomatic and have non-specific symptoms, making most cases difficult to detect early. The aim of this study was to investigate genitourinary features of ovarian tumor in a hospital-based study. An observational study was conducted in Baghdad, Iraq, between September 2018 and February 2021. Women diagnosed with ovarian tumors at 18 years of age or older. A total of Fifty women who enrolled in our hospital. Clinical and pathological data collected and analyzed. Data about comorbidities and outcomes were approved and diagnosed by full team of multidisciplinary gynecological and urological doctors were recorded. Overall incidence of ovarian tumors was 70% malignant and 30% benign. The study showed that the most age group of ovarian tumors was above 55 years (62%). Half of patients were nulliparities. Educational level was mostly of low level in illiterate (20%), primary (24%), secondary (36%) compared to high level. Women used contraception in 52%. The family history reported in 18% of women. The most common histopathological type was ovarian serous carcinoma 15(30%). Regional stages were common in 50% of patients. Low grade tumors in 32%, intermediate in 36% and high in 32%. Almost, 80% of women underwent TAH. About 60% of patients received chemotherapy. The long-term adverse genitourinary health outcomes correlated included Nephritis (6%), Acute renal failure (16%), Chronic kidney disease (18%), UTI (38%), Calculus (16%), Hydronephrosis (20%), Bladder obstruction (2%), Ureteric stenosis (12%), Urine retention (8%), Urine incontinence (12%), Hematuria (22%), PID (14%), Organ adhesion (8%), Cervicitis (2%), Endometriosis (2%), Cyst (6%), Menstrual disorders (24%), Infertility (2%), and Menopausal pain (32%). In conclusion, ovarian cancer represents the third most common gynecologic cancer type. It was more common in women aged above five decades. The most common histopathological type is ovarian serous carcinoma. We observed that ovarian cancer survivors experienced increased risks of various genitourinary diseases. Understanding the multi-morbidity scenarios for ovarian tumors is of vital importance to improve clinical care after diagnosis.

RESUMO

Fosfomycin tromethamol (FT) was reintroduced as an option for the treatment of low urinary tract infection (UTI) in children. In this study, we described the antibiotic sensitivity and mechanisms of resistance to fosfomycin in isolates from children older than 6 years with UTI. Urine culture and antibiotic susceptibility study were performed. In fosfomycin resistant strains, PCR for fos, blaCTX-M was performed followed by classification by phylogenetic group and sequencetyping. Escherichia coli was the most frequent etiological agent (89.2%). The susceptibility percentages were: fosfomycin 97.9%; amoxicillin-clavulanate 92.7%; cefuroxime and ceftriaxone 99%; nitrofurantoin 94.4%. An E. coli strain (ST69, phylogenetic group D) was resistant to fosfomycin (MIC 256mg/l) and carried the blaCTX-M-14 and fosA3 genes in a 45kb IncN-type plasmid.


La fosfomicina-trometamol (FT) se reintrodujo como una opción para el tratamiento de la infección del tracto urinario (ITU) baja en niños. En este estudio describimos la sensibilidad antibiótica y los mecanismos de resistencia a FT en aislamientos de niños mayores de 6 anos con ITU. Se realizaron urocultivos y estudios de sensibilidad antibiótica. En las cepas resistentes a fosfomicina se realizó la técnica de PCR para fos, blaCTX-M, y su identificación según su grupo filogenéticoy secuenciotipo. Escherichiacoli fue el agente etiológico más frecuente (89,2%). Los porcentajes de sensibilidad fueron: fosfomicina 97,9%; amoxicilina-clavulánico 92,7%; cefurox-ima y ceftriaxona 99%; nitrofurantoína 94,9%. Una cepa de E. coli (ST69, grupo filogenético D) fue resistente a fosfomicina (CIM 256mg/l) y portaba los genes blaCTX-M-14 y fosA3 en un plás-mido de 45 kb del tipo IncN. Este es el primer reporte de E. coli ST69 con blaCTX-M-14/fosA3 de origen humano.

RESUMO

Resumen Objetivo: Determinar los factores asociados, las características clínicas, microbiológicas y perfiles de resistencia en las infecciones sintomáticas de tracto urinario asociado a catéter (ISTU-AC) en los dos Instituciones de alto nivel de complejidad. Materiales y métodos: Se llevó a cabo un estudio de casos y controles. Se incluyeron todos los pacientes con más de 48 horas de hospitalización con inserción de catéter urinario y se recolectaron todas las variables clínicas y microbiológicas de cada paciente. Se incluyeron 446 pacientes, 223 con infección sintomática del tracto urinario asociado a catéter. El análisis multivariado se realizó por medio de regresión logística. Resultados: Se evidenció una mayor proporción de hombres en los controles (60,5%) en comparación con los casos (51,1%), la mediana de la edad fue muy similar para los dos grupos de estudio. Se evidenció por el análisis de regresión logística multivariado que la estancia en UCI (OR 2,176; IC de 95% 1,332 - 3,555), más de 10 días de catéter urinario (OR 2,907; IC de 95% 1,744 - 4,846) y la terapia antibiótica previa (OR 0,060; IC de 95% 0,037 - 0,103) fueron los principales factores asociados con la ocurrencia de ISTU-AC. No se encontró asociación entre presentar el evento de interés y la edad, esta variable no está relacionada con la pre sencia de infecciones intrahospitalarias. Es probable que las comorbilidades, presentes con más frecuencia en el adulto mayor, hayan sobrepasado el efecto de la edad en esos estudios. La asociación con género no fue identificada como un factor de riesgo, lo cual podría esperarse, dado que el uso de la sonda vesical hace equiparable el riesgo entre los hombres y las mujeres. Conclusiones: Este estudio mostró que la infecciones sintomáticas de tracto urinario asociado a catéter sigue siendo la entidad más frecuente) en el ámbito hospi talario, poniendo en riesgo la seguridad de los pacientes y aumentando tanto las tasas de morbi-mortalidad


Summary Objective: To determine the associated factors, clinical and microbiological characteristics, and resistance profiles in symptomatic urinary tract infections associated with catheters in the two institutions with a high level of complexity. Materials and methods: A case-control study was carried out. All patients with more than 48 hours of hospitalization with urinary catheter insertion were included and all the clinical and microbiological variables of each patient were collected. 446 patients were included, 223 with symptomatic urinary tract infection associated with a catheter. The multivariate analysis was carried out by means of logistic regression. Results: A greater proportion of men was evidenced in the controls (60.5%) compared to the cases (51.1%), the median age was very similar for the two study groups. It was evidenced by the multivariate logistic regression analysis that the stay in the ICU (OR 2.176; 95% CI 1.322 - 3.555), more than 10 days of urinary catheter (OR 2.907; 95% CI 1.744 - 4.846) and antibiotic therapy previous (OR 0.060; 95% CI 0.037 - 0.103) were the main factors associated with the occurrence of CA-UTI. No association was found between presenting the event of interest and age, this variable is not related to the presence of intrahospital infections. Co morbidities, which are more frequently present in the elderly, are likely to have outweighed the effect of age in these studies. The association with gender was not identified as a risk factor, which could be expected, since the use of the urinary catheter makes the risk comparable between men and women. Conclusions: This study showed that symptomatic urinary tract infections associated with catheters are still a frequent entity in the hospital setting, putting the safety of patients at risk and increasing both morbidity and mortality rates

RESUMO

RESUMEN Introducción: las infecciones urinarias intrahospitalarias son una problemática desde las perspectivas clínica, epidemiológica y terapéutica. El 70 % se presentan en pacientes cateterizados, y generan un importante impacto sobre la morbimortalidad, y costos asociados al proceso de atención. Objetivo: determinar los microorganismos que incidieron en la infección urinaria de los pacientes ingresados y relacionar la misma con catéter vesical. Materiales y métodos: se realizó un estudio observacional, descriptivo y retrospectivo. Los casos correspondieron a 171 muestras de orina que se recibieron en el laboratorio de Microbiología del Hospital Clínico Quirúrgico Interprovincial Ambrosio Grillo, de Santiago de Cuba, entre enero y septiembre de 2019, obtenidas de los pacientes cateterizados ingresados en dicho centro asistencial, con diagnóstico de infección urinaria. Resultados: predominaron los pacientes del sexo femenino con más de 65 años de edad. El patógeno más aislado en los cultivos de orina fue Escherichia coli; el parcial de orina tuvo un ligero aumento en la sensibilidad; con relación a los urocultivos de los pacientes con infección urinaria, hubo un 34,5 % de estos con catéter vesical por más de siete días. Conclusiones: la utilización de dispositivos invasivos es un factor de riesgo significativo en el desarrollo de infección urinaria intrahospitalaria.


ABSTRACT Introduction: intra-hospital urinary infections are a problem from the clinical, epidemiological and therapeutic perspectives. 70 % are present in catheterized patients, and generate an important impact on morbidity and mortality, and on the costs associated with the care process. Objective: to determine the microorganisms that impacted on the urinary infection of the hospitalized patients and to relate it to vesical catheter. Materials and methods: an observational, descriptive and retrospective study was carried out. The cases corresponded to 171 urine samples that were received at the Microbiology laboratory of the Interprovincial Clinical Surgical Hospital Ambrosio Grillo, of Santiago de Cuba, between January and September 2019, obtained from catheterized patients admitted to that care facility with diagnosis of urinary infection. Results: female patients over 65 years old predominated. The most isolated pathogen in urine cultures was Escherichia coli; urine partial had a slight increase in sensitivity; in relation to urocultures of patients with urinary infection, 34.5 % of them had vesical catheter for more than seven days. Conclusions: the use of invasive devices is a significant risk factor in the development of intra-hospital urine infection.

RESUMO

OBJECTIVES:  Emerging urinary infections by rare germs are a public health problem. The objectives of this article are to review urinary tract infections caused by an emerging genus of bacteria called Raoultella and to report a case of asymptomatic urinary tract infection by Raoultella ornithinolytica. MATERIALS AND METHODS:  A review of publications on urinary tract infections caused by the genus Raoultella between 2009 and 2018 is carried out and a case of asymptomatic urinary tract infection by Raoultella ornithinolytica is reported. The search of articles in Medline/ Pubmed and Google was performed with the keywords: Raoultella, Raoultella ornithinolytica, urinary tract infection. Twelve variables were studied: year of publication, authors, specialty, type of infection, number of cases, sex, age, immunosuppression, oncological patient, urological instrumentation, urological surgery and neurogenic bladder. Results were analyzed using descriptive statistics. A new case is described. RESULTS:  24 publications were found with 120 cases of urinary infections of the genus Raoultella between 2009 and 2018, corresponding to Raoultella ornithinolytica 40.8%, Raoultella planticola 28.3%, Raoultella terrigena 30.8% and Raoultella electrica 0%. The series included 43 men (35.8%), 53 women (44.1%) and 24 patients with this data not provided (20%). The minimum age was 14 days, the maximum was 97 years and the average age was 56.6. The types of infection detected were: uncomplicated UTI 94.1%, UTI in newborn 1.6%, acute prostatitis 0.8%, chronic prostatitis 0.8%, giant kidney cyst infection 0.8%, calculous pyelonephritis 0.8% and recurrent cystitis 0.8%. CONCLUSIONS:  Urinary tract infections by species of the genus Raoultella occur in immunocompromised, oncological, instrumented or basic urological patients. The species Raoultella ornithinolytica described in 2011 is an emerging germ in urinary infections. This contribution is the second Spanish publication and twelfth worldwide of urinary infection by Raoultella ornithinolytica.

RESUMO

BACKGROUND AND OBJECTIVE: Adequate empirical treatment should be established for treatment urinary tract infections, considering the prevalence of the most frequent microorganisms in each geographic area and their susceptibility to different antibiotics. The objective of the study is to analyze the epidemiology of UTIs in our Health Area as well as to understand the antibiotic susceptibility of the most prevalent isolated microorganisms to guide empirical treatment. The objective was to establish a reasoned system for recommending ITU empirical therapy, based on the microorganisms causing episodes assisted in a Regional Hospital, knowing their antibiotic susceptibility. PATIENTS AND METHODS: A descriptive-retrospective study was carried out based on the results of 12,204 urine cultures of the year 2018. The overall empirical activity of the antibiotics tested was calculated, differentiating between episodes of the community and of in patients, adults and children. RESULTS: Escherichia coli was the most frequently isolated microorganism in all studied groups. The following microorganisms in frequency, in adults, were Enterococcus faecalis, Klebsiella pneumoniae and yeasts (8%). In the group of children these were Enterococcus faecalis and Proteus mirabilis. There was no difference in the activity of antibiotics against Escherichia coli, in adults or in children, of the community or in patients, with sensitivityto fosfomycin and nitrofuranto in greater than 96%; at imipenem and piperacillin-tazobactam greater than 94% and third generation cephalosporins greater than 90%. However, the overall empirical activity, without distinction by microorganism, was for fosfomycin 77.96-80.60% in adults and 92.73-94.50% in children; to prevent 77.70-78.74% in adults and 92.36-91.28% in children; for piperacillin-tazobactam of 77.57-80.03% in adults and 89.09-94.04% in children; and for cefotaxime of 53.28-54.76% in adults and 68.73-74.77% in children. CONCLUSIONS: Fosfomycin, piperacillin-tazobactam or imipenem were the best option for empirical treatment without covering all episodes in adults. Each Center must establish a reasoned profile of empirical treatment of the infection, which should also take into account risk factors for a microorganism and clinical severity.


ANTECEDENTES Y OBJETIVO: Se debe establecer un tratamiento empírico adecuado que acabe con la mayor parte de las infecciones del tracto urinario (ITU), teniendo en cuenta la prevalencia de los microorganismos más frecuentes en cada área geográfica y la sensibilidad de estos a los distintos antibióticos. El objetivo del estudio es analizar la epidemiología de las ITU en nuestra Área Sanitaria, así como conocer la sensibilidad antibiótica de los microorganismos aislados más prevalentes para orientar el tratamiento empírico. PACIENTES Y MÉTODOS: Se realizó un estudio descriptivo-retrospectivo a partir de los resultados de12.204 urocultivos del año 2018. Se calculó la actividad empírica global de los antibióticos ensayados, diferenciando entre episodios de la comunidad y de pacientes hospitalizados, adultos y niños. RESULTADOS: Escherichia coli fue el microorganismo más frecuentemente aislado en todos los grupos estudiados. Los siguientes microorganismos en frecuencia, en los adultos, fueron Enterococcus faecalis, Klebsiella pneumoniae y levaduras (8%). En el grupo de los niñosestos fueron Enterococcus faecalis y Proteus mirabilis.N o hubo diferencia en la actividad de los antibióticos frente a Escherichia coli, en adultos o en niños, de la comunidad u o hospitalizado, con sensibilidad a fosfomicina y nitrofurantoína superior al 96%; a imipenem y piperacilina-tazobactam superior al 94% y cefalosporinas de tercera generación superior al 90%. Sin embargo,la actividad empírica global, sin distinción por microorganismo, fue para fosfomicina del 77,96-80,60% en adultos y del 92,73-94,50% en niños; para imipenem del 77,70-78,74% en adultos y del 92,36-91,28% en niños; para piperacilina-tazobactam del 77,57-80,03% en adultos y del 89,09-94,04% en niños; y para cefotaxima del 53,28-54,76% en adultos y del 68,73-74,77% en niños. CONCLUSIONES: Fosfomicina, piperacilina-tazobactame imipenem fueron la mejor opción de tratamiento empírica, sin cubrir todos los episodios en los adultos. Cada centro de trabajo debe establecer un perfil razonado de tratamiento empírico de la infección, que además deben tener en cuenta los factores de riesgo para un microorganismo y la gravedad clínica.

RESUMO

INTRODUCTION AND OBJECTIVES: Radical cystectomy with urinary diversion associated with extended pelvic lymphadenectomy continues to be the treatment of choice in muscle invasive bladder cancer. Sixty-four percent of patients submitted to this procedure present postoperative complications, with urinary infection being responsible in 20-40% of cases. The aim of this project is to assess the rate of urinary infection as a cause of re-admission after cystectomy, and to identify protective and predisposing factors for urinary infection in our environment. Finally, we will evaluate the outcomes after the establishment of a prophylactic antibiotic protocol after removal of ureteral catheters. MATERIAL AND METHODS: Retrospective descriptive study of cystectomized patients in the Urology Service of the Hospital Clínico Universitario of Zaragoza, from January 2012 to December 2018. A urinary tract infection (UTI) prevention protocol after catheter removal is established for all patients since October 2017. RESULTS: UTI is responsible for 54.7% of readmissions, with 55.1% of these being due to UTI after removal of ureteral catheters. Of the patients who received with prophylaxis, 9.5% presented UTIs after withdrawal, compared to 10.6% in the group of patients without prophylaxis. The patient who is re-admitted for UTI after withdrawal has a mean catheter time of 24.3±7.2 days, compared to 24.5±7.4 days for patients in the group without UTI (P=.847). CONCLUSIONS: The type of urinary diversion performed is not related to the rate of urinary infection. The regression model does not identify antibiotic prophylaxis, nor catheter time, as independent factors of UTI after catheter removal.

RESUMO

OBJECTIVES: To determine the prevalence of patients with bladder catheterization in a geriatrics service and to analyze the factors associated with the use of urinary catheterization in hospitalized elderly people. MATERIAL AND METHOD: This descriptive and retrospective study (January to December 2019) included all the patients admitted to a geriatric service, with bladder catheterization during their hospital admission. Sociodemographic and clinical data were collected. RESULTS: In 2019, 10.20% of the patients admitted required urinary catheters. Most of these patients were males (60.6%), with an average age of 86.5 years (SD: 8.65). 43.4% of the urinary catheters that were placed temporarily were indicated in the geriatric unit, 28.9% in another medical service and 26.3% in the emergency department. The median of days with a urinary catheter was 7.5 days. The most common reason to indicate a urinary catheter was acute urinary retention (AUR) (67.7%). At hospital discharge, 22.3% of the patients needed to continue with a urinary catheter at home, without needing it prior to admission. CONCLUSIONS: In our study, a high percentage of bladder catheterization was needed during the hospitalization, the most common cause being AUR. The average use (in days) of urinary catheters is high, with the consequent risk of nosocomial urinary tract infections. It is necessary to improve the prescribing habits of urinary catheterization and its early withdrawal through specific educational efforts and avoiding their inappropriate use.
