Bacterial profile and prevalence of urinary tract infections in pregnant women in Latin America: a systematic review and meta-analysis.

BACKGROUND: Given the physiological changes during pregnancy, pregnant women are likely to develop recurrent urinary tract infections (UTIs) and pyelonephritis, which may result in adverse obstetric outcomes, including prematurity and low birth weight preeclampsia. However, data on UTI prevalence and bacterial profile in Latin American pregnant women remain scarce, necessitating the present systematic review to address this issue. METHODS: To identify eligible observational studies published up to September 2022, keywords were systematically searched in Medline/PubMed, Cochrane Library, Embase, Web of Science, and Bireme/Lilacs electronic databases and Google Scholar. The systematic review with meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the quality of studies was classified according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. The meta-analysis employed a random-effects method with double-arcsine transformation in the R software. RESULTS: Database and manual searches identified 253,550 citations published until September 2022. Among the identified citations, 67 met the inclusion criteria and were included in the systematic review, corresponding to a sample of 111,249 pregnant women from nine Latin American countries. Among Latin American pregnant women, the prevalence rates of asymptomatic bacteriuria, lower UTI, and pyelonephritis were estimated at 18.45% (95% confidence interval [CI]: 15.45-21.53), 7.54% (95% CI: 4.76-10.87), and 2.34% (95% CI: 0.68-4.85), respectively. Some regional differences were also detected. Among the included studies, Escherichia coli (70%) was identified as the most frequently isolated bacterial species, followed by Klebsiella sp. (6.8%). CONCLUSION: Pregnant women in Latin America exhibit a higher prevalence of bacteriuria, UTI, and pyelonephritis than pregnant women globally. This scenario reinforces the importance of universal screening with urine culture during early prenatal care to ensure improved outcomes. Future investigations should assess the microbial susceptibility profiles of uropathogens isolated from pregnant women in Latin America. TRIAL REGISTRATION: This research was registered at PROSPERO (No. CRD42020212601).

Treatment of asymptomatic bacteriuria in the first 2 months after kidney transplant: A controlled clinical trial.

BACKGROUND: The incidence of urinary tract infections (UTIs) in the first 2 months postrenal transplantation (pRT) is very high. We evaluate the efficacy of asymptomatic bacteriuria (AB) screening and treatment on the incidence of UTI in the first 2 months pRT METHODS: We conducted a randomized controlled clinical trial. A urine culture was obtained in all patients on the day of the bladder catheter removal, on week three, and before removal of the ureteral catheter. The intervention group received treatment for AB. The control group did not receive treatment. The primary outcomes were the cumulative incidence of UTI and/or graft pyelonephritis and the time to the first episode of UTI and/or graft pyelonephritis RESULTS: Eighty patients were randomized, 40 in each group, and the median follow-up was 63 days (IQR 54-70). The average age was 29.8 years and 33.7% (n = 27) were women. The incidences of UTI (n = 10, 25 % vs. n = 4, 10%, p = .07) and pyelonephritis (n = 6, 15% vs. n = 1, 2.5%, p = .04) were greater in the intervention group, as also shown in the survival analysis: UTI (HR2.8, 95% CI 0.8-9.1, p = .07) and pyelonephritis (HR 6.5, 95% CI 0.8-54.7, p = .08), respectively. The most commonly isolated bacterium was Escherichia coli (n = 28, 59.5%), and over half were E. coli with extended-spectrum beta-lactamases (n = 15). A major limitation was not obtaining the calculated sample size due to a delay in patient recruitment resulting from the COVID-19 pandemic CONCLUSION: Treatment of AB in the first 2 months pRT does not decrease the incidence of UTI or graft pyelonephritis and may actually increase their frequency. Routine treatment of AB during the first months after renal transplantation should not be a standard procedure.

Facklamia hominis pyelonephritis in a pediatric patient: first case report and review of the literature.

BACKGROUND: Pyelonephritis is one of the most serious bacterial illnesses during childhood. Gram-negative organisms account for up to 90% of the cases. Gram-positive bacteria are uncommon causes of urinary tract infections, and only a few cases caused by Facklamia hominis have been reported in the literature. CASE PRESENTATION: A five-year-old girl with tracheostomy and gastrostomy and past medical history of congenital lymphangioma presented with a two-week history of with intermittent fever, frequent urination, and vesical tenesmus. Diagnosis of pyelonephritis was made. Urine culture reported colonies with alpha-hemolysis in blood agar at 48-h of incubation and Facklamia hominis was identified by MALDI-TOF. The patient was successfully treated with gentamicin. CONCLUSIONS: This is the first reported case of pyelonephritis by Facklamia hominis in a child, and the second involving infection in a pediatric patient. Although this pathogen is uncommon, current treatment of F. hominis is a challenge for physicians. This case illustrates the requirement to standardize identification and treatment of care to avoid treatment failure and antimicrobial resistance.

La Sociedad Argentina de Infectología y otras sociedades científicas han actualizado estas recomendaciones utilizando, además de información internacional, la de un estudio multicéntrico prospectivo sobre infecciones del tracto urinario del adulto realizado en Argentina durante 2016-2017. La bacteriuria asintomática debe ser tratada solo en embarazadas, a quienes también se las debe investigar sistemáticamente; los antibióticos de elección son nitrofurantoína, amoxicilina, amoxicilina-clavulánico, cefalexina y trimetoprima-sulfametoxazol. Ante procedimientos que impliquen lesión con sangrado del tracto urinario se recomienda solicitar urocultivo para pesquisar bacteriuria asintomática, y, si resultara positivo, administrar antimicrobianos según sensibilidad desde inmediatamente antes hasta 24 horas luego de la intervención. En mujeres, la cistitis puede ser tratada con nitrofurantoina, cefalexina, o fosfomicina y no se recomienda usar trimetoprima-sulfametoxazol o fluoroquinolonas; en pielonefritis puede emplearse ciprofloxacina, cefixima o cefalexina si el tratamiento es ambulatorio o ceftriaxona, cefazolina o amikacina si es hospitalario. En los hombres, las infecciones del tracto urinario se consideran siempre complicadas. Se recomienda tratamiento con nitrofurantoina o cefalexina por 7 días, o bien monodosis con fosfomicina. Para la pielonefritis en hombres se sugiere ciprofloxacina, ceftriaxona o cefixima si el tratamiento es ambulatorio y ceftriaxona o amikacina si es hospitalario. Se sugiere tratar las prostatitis bacterianas agudas con ceftriaxona o gentamicina. En cuanto a las prostatitis bacterianas crónicas, si bien su tratamiento de elección hasta hace poco fueron las fluoroquinolonas, la creciente resistencia y ciertas dudas sobre la seguridad de estas drogas obligan a considerar el uso de alternativas como fosfomicina.

The Argentine Society of Infectious Diseases and other scientific societies have updated these recommendations based on data on urinary tract infections in adults obtained from a prospective multicenter study conducted in Argentina during 2016-2017. Asymptomatic bacteriuria should be treated only in pregnant women, who should also be systematically investigated; the antibiotics of choice are nitrofurantoin, amoxicillin, clavulanic/amoxicillin, cephalexin and trimethoprim-sulfamethoxazole. In procedures involving injury to the urinary tract with bleeding, it is recommended to request urine culture and, in the presence of bacteriuria, antimicrobial treatment according to sensitivity should be prescribed from immediately before up to 24 hours after the intervention. In women, cystitis can be treated with nitrofurantoin, cephalexin or fosfomycin, while trimethoprim-sulfamethoxazole and fluoroquinolones are not recommended; pyelonephritis can be treated with ciprofloxacin, cefixime or cephalexin in ambulatory women or ceftriaxone, cefazolin or amikacin in those who are hospitalized. In men, urinary tract infections are always considered complicated; nitrofurantoin or cephalexin are recommended for 7 days, alternatively fosfomycin should be given in a single dose. In men, ciprofloxacin, ceftriaxone or cefixime are suggested for pyelonephritis on ambulatory treatment whereas ceftriaxone or amikacin are recommended for hospitalized patients. Acute bacterial prostatitis can be treated with ceftriaxone or gentamicin. Fluoroquinolones were the choice treatment for chronic bacterial prostatitis until recently; they are no longer recommended due to the increasing resistance and recent concerns regarding the safety of these drugs; alternative antibiotics such as fosfomycin are to be considered.

Coexistence of emphysematous cystitis and bilateral emphysematous pyelonephritis: a case report and review of the literature.

Emphysematous pyelonephritis (EPN) is a necrotizing infection characterized by the production of gas in the renal parenchyma, collecting system or perirenal tissue. Meanwhile, emphysematous cystitis (EC) is a clinical entity characterized by the presence of gas inside and around the bladder wall. Interestingly, although both diseases are common in patients with diabetes mellitus, these are rarely combined. We report a rare case of a 56-year-old diabetic male suffering from fever, headache and vomiting and in which a diagnosis of septic shock was established due to coexistence of EC and bilateral EPN. The emphysematous diseases improved with a conservative treatment approach using antibiotic therapy and glycemic control, we highlight that the nephrectomy was not necessary in our patient despite the fact that he presented risk factors that predict the failure of conservative treatment.

The Use of Mobile Educational Tools to Improve Antimicrobial Prescription for the Treatment of Acute Pyelonephritis in Pregnancy: A Retrospective Cross-sectional Study.

OBJECTIVE: To analyze the prescription of antimicrobial agents for pregnant women admitted into the obstetrics service who presented with acute pyelonephritis. METHODS: Three cross-sectional studies were performed comparing the prescription of antimicrobials for pyelonephritis in pregnant women in the time periods evaluated (2010-2011: 99 patients evaluated; 2013: 116 patients evaluated; 2015: 107 patients evaluated), at the Hospital Fêmina, Porto Alegre, in the state of Rio Grande do Sul, Brazil. The analysis was performed before and after the promotion of an institutional protocol for the treatment of pyelonephritis during pregnancy, and on a third occasion after the introduction of a smartphone-based mobile educational tool. RESULTS: The evaluation of the prescribing physicians and the adequacy of the prescriptions between the different periods studied revealed a significant increase in appropriate conduct for the choice of antimicrobial (2010: 83.8%; 2013: 95.7%; and 2015: 100%), route of administration (2010: 97%; 2013: 100%; and 2015: 100%), and interval (2010: 91.9%; 2013: 95.7%; and 2015: 100%), following the introduction of the protocol, and again after the implementation of the software application with orientations on the antimicrobial treatment. CONCLUSION: The use of specific mobile applications should be encouraged to attain a better quality and accuracy in prescriptions and to include strategies that not only reduce the risk of negative outcomes, but also improve the quality of care and treatment for maintaining the health both of the mother and of the baby.

Infecção urinária multirresistente na gravidez / Multiresistant urinary infection in pregnancy

Os micro-organismos que apresentam mecanismos de resistência aos antimicrobianos, como produção de ß-lactamase de espectro estendido (ESBL), resultam em uma maior dificuldade no tratamento e exigem a utilização de antibióticos de largo espectro com frequência crescente. Assim, este estudo busca revisar a literatura sobre as infecções causadas por micro-organismos multirresistentes na gravidez. Foi realizada uma busca de artigos no PubMed, MedLine e Lilacs usando-se unitermos, incluindo-se os estudos publicados de 2000 a 2016, de línguas portuguesa e inglesa, envolvendo apenas seres humanos. Foram selecionados 59 artigos com força de evidência A e B. Os critérios para inclusão no estudo são: estarem grávidas e terem diagnóstico de infecção do trato urinário. Serão critérios de exclusão: uso de antimicrobiano a menos de duas semanas antes da coleta da amostra e portadoras de doença imunossupressora. A verdadeira prevalência de ITU em gestantes por bactérias multirresistentes é desconhecida. As ITUs por bactérias produtoras de ESBL variam entre 1% e 40%. O tratamento mais aceito para os casos mais graves (pielonefrite ou bacteremia) é com carbapenêmicos. A nitrofurantoína e a fosfomicina têm sido utilizadas para tratar a cistite com patógenos produtores de ESBL com sucesso.(AU)

Microorganisms that have resistance mechanisms to antimicrobial agents, such as production of ß-lactamase extended spectrum (ESBL), result in greater difficulty in treatment and require the use of broad spectrum antibiotics with increasing frequency. This study aims to review the literature on infections caused by multiresistant microorganisms in pregnancy. A search for articles was conducted in PubMed, MedLine and Lilacs are using key words, including published studies from 2000 to 2016, Portuguese and English, involving only human. 59 articles were selected on strength of evidence A and B. The criteria for inclusion was pregnant and having diagnosed of urinary tract infection. The criteria for exclusion was: use of antimicrobial less than two weeks before sample collection and suffering from immunosuppressive disease. The true prevalence of UTI in pregnant women by multiresistant bacteria is unknown. UTIs for ESBL-producing bacteria, ranging from 1% to 40%. The treatment more acceptable for the most serious cases (pyelonephritis or bacteremia) is with carbapenems. Nitrofurantoin and fosfomycin has been used to treat successfully with cystitis ESBL producers pathogens.(AU)

[Uncomplicated urinary tract infection in women: etiology and antimicrobial resistance]. / Infección urinaria no complicada en mujeres: etiología y resistencia a antimicrobianos.

Our objectives were to determine the etiology and analyze the antibiotic resistance profiles of microorganisms causing uncomplicated urinary tract infections in our setting. An analytical cross-sectional study was conducted. In vitro antimicrobial resistance of urine cultures was analyzed. 580 urine cultures of women over age fifteen were included. 82.6 % of urine cultures corresponded to cystitis and the remaining 17.4 % corresponded to pyelonephritis. 353 urine cultures of women <50 years old (60.9%) and 227 of women = 50 years old (39.1%) were obtained. The most common pathogens were Escherichia coli (85.5 %) and Klebsiella pneumoniae (4.7 %). For Escherichia coli, there was a resistance of 28.6% to trimethoprim-sulfamethoxazole,7.9% to ciprofloxacin and 0.4% to nitrofurantoin. Significant difference (p = 0.005) was seen in the resistance to ciprofloxacin in women = 50 years old. Our data show there is a low in vitro resistance to nitrofurantoin

Nuestros objetivos fueron determinar la etiología y analizar los perfiles de resistencia antimicrobiana de los microorganismos causantes de infecciones urinarias no complicadas en nuestro medio. Se realizó un estudio analítico de corte transversal. Se analizó la resistencia antimicrobiana in vitro de los urocultivos. Se incluyeron 580 urocultivos de mujeres mayores de 15 años.

Se encontró una resistencia de E coli a trimetoprima-sulfametoxazol del 28.6%, a ciprofloxacina de 7.9% y a nitrofurantoína de 0.4%. Se evidenció diferencia significativa (p=0.005) en la resistencia de E coli a ciprofloxacina en las mujeres ?50 años de edad. Nuestros datos muestran que existe una baja resistencia in vitro a nitrofurantoína.

Caso Clínico: Pielonefritis Enfisematosa / Case Report: Emphysematous Pyelonephritis

INTRODUCCIÓN: La pielonefritis enfisematosa (PEN) es una infección aguda grave y en ocasiones fulminante, se manifiesta con necrosis y presencia de gas en el parénquima renal y tejido perirrenal. CASO CLÍNICO: Se trata de una paciente de sexo femenino de 60 años con antecedentes de diabetes mellitus tipo 2 e hipertensión arterial; ingresa por cuadro de dolor lumbar, malestar general, astenia y nausea que llevó al vómito. Al examen físico se evidenció puño percusión izquierda positiva e hiperglicemia. Se realizaron estudios complementarios que establecieron el diagnóstico de pielonefritis enfisematosa. EVOLUCIÓN: Se inició tratamiento antibiótico de amplio espectro para Escherichia coli, posteriormente fue necesario someter a la paciente a nefrectomía total por la imposibilidad de drenaje percutáneo de lesiones intra y perirrenales. La evolución fue favorable después de una nueva intervención y rotación del esquema antibiótico. CONCLUSIÓN: Se establece la necesidad de la sospecha clínica para determinar de forma precoz el diagnóstico, mismo que puede evitar la necesidad de terapias radicales como la nefrectomía.(au)

BACKGROUND: Emphysematous pyelonephritis is a severe acute infection and fulminant sometimes. Its manifestations include necrosis and presence of gas in the kidney parenchyma and around it. CASE REPORT: This is about a 60-years old female patient with precedent diagnosis of type 2 diabetes mellitus and arterial hypertension; she was admitted because of back pain, general malaise, asthenia, nausea and vomit. Physical examination revealed positive fist percussion at right back and hyperglycemia. Complementary exams were performed and emphysematous pyelonephritis diagnosis was established. EVOLUTION: Broad spectrum antibiotic therapy was used to treat Escherichia coli and a complete nephrectomy was performed lately due to impossibility to perform a percutaneous drainage of kidney injuries. Evolution was successful after another intervention and rotation of antibiotic scheme. CONCLUSION: Need of diagnostic suspicion was established to complete an early diagnosis, which may avoid radical therapies as nephrectomy.(au)

Pyelonephritis (acute) in non-pregnant women.

INTRODUCTION: Pyelonephritis is usually caused by ascent of bacteria (most often Escherichia coli) from the bladder, and is more likely in people with structural or functional urinary tract abnormalities. The prognosis is good if pyelonephritis is treated appropriately, but complications include renal abscess, renal impairment, and septic shock. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of antibiotic treatments for acute pyelonephritis in non-pregnant women with uncomplicated infection? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found four studies that met our inclusion criteria. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (intravenous), antibiotics (oral), and antibiotics (switch therapy).

Renal abscess in hyper-IgE syndrome.

Kidney disease due to Aspergillus fumigatus is a rare finding in hyper-IgE syndrome. We report a patient with autosomal dominant hyper-IgE syndrome, recurrent pneumonia, and acute necrosuppurative pyelonephritis caused by Aspergillus fumigatus with a fatal outcome. We emphasize the severity and the difficulties in the management of renal complications that could be limiting the survival of these patients.

[Results of two treatment regimens for pyelonephritis during pregnancy and correlation with pregnancy outcome]. / Resultados de dois esquemas de tratamento da pielonefrite durante a gravidez e correlação com o desfecho da gestação.

PURPOSE: To determine the epidemiological profile of women admitted for urinary tract infection as well as to verify the most prevalent agents and response to antibiotic therapy. METHODS: A retrospective study of 106 pregnant women admitted to a university hospital for urinary tract infection treatment during the period between January 2007 to December 2010. The evaluation was based on analysis of the medical records of these pregnant women, with the observation of hospitalization and pregnancy data, as well as its outcome. Statistical analysis was performed using Statistical Package for the Social Science, version 15.0. The bilateral Fisher exact test and Student's t test were used for data analysis, as well as descriptive statistical methods. RESULTS: Positive urine cultures were observed in 60.5% of pregnant women admitted due to urinary tract infection. The most frequent infectious agent was Escherichia coli and no difference in resistance, recurrence or complications was observed between the most frequent etiologic agents. Pregnant women with previous UTI had a higher recurrence risk (OR=10.8; p<0.05). The antibiotics most commonly used during hospitalization were ampicillin and cefazolin. Change of therapeutic agent due to bacterial resistance occurred in 11.9% of patients who took cefazolin and in 20% of patients who took ampicillin (OR=5.5; p<0.05). The rate of gestational complications was the same for both treatments. There was no difference in mean number of days of hospitalization between the treatments. CONCLUSION: In the studied population ampicillin showed a higher rate of bacterial resistance than cefazolin, requiring a larger number of treatment regimen exchanges, without resulting in differences in clinical outcome or time of hospitalization.

Resultados de dois esquemas de tratamento da pielonefrite durante a gravidez e correlação com o desfecho da gestação / Results of two treatment regimens for pyelonephritis during pregnancy and correlation with pregnancy outcome

OBJETIVO: Determinar o perfil epidemiológico das gestantes internadas por infecção do trato urinário, bem como verificar os agentes mais prevalentes e a resposta à antibioticoterapia. MÉTODOS: Estudo retrospectivo, que incluiu 106 gestantes internadas para tratamento de infecção do trato urinário no período entre janeiro de 2007 a dezembro de 2010. A avaliação constituiu-se de análise de prontuários dessas gestantes, observando-se informações sobre a internação e a gestação, bem como seu desfecho. Foi realizada a análise estatística por meio do programa Statistical Package for the Social Science, versão 15.0. Foram utilizados, para análise dos dados, o teste bilateral exato de Fisher e o teste t de Student, bem como métodos de estatística descritiva. RESULTADOS: Uroculturas positivas foram encontradas em 60,5% das gestantes internadas por infecção do trato urinário. O agente infeccioso mais frequente foi Escherichia coli e não houve diferença quanto à resistência, à recorrência ou a complicações entre os agentes etiológicos mais frequentes. Gestantes com infecção do trato urinário prévia tiveram maior risco de recorrência (OR=10,8; p<0,05). Os antibióticos mais frequentemente utilizados na internação foram ampicilina e cefazolina. Troca de esquema terapêutico por resistência bacteriana ocorreu em 11,9% das pacientes que usaram cefazolina e em 20% das que usaram ampicilina (OR=5,5; p<0,05). O índice de complicações gestacionais foi igual nos dois tratamentos. Não houve diferença entre as médias do número de dias de internação para os dois tratamentos. CONCLUSÃO: A ampicilina esteve associada a maior índice de resistência bacteriana que a cefazolina, necessitando de maior número de trocas do esquema terapêutico, sem resultar em diferença nos desfechos clínicos e tempo de internação.

RESULTS: Positive urine cultures were observed in 60.5% of pregnant women admitted due to urinary tract infection. The most frequent infectious agent was Escherichia coli and no difference in resistance, recurrence or complications was observed between the most frequent etiologic agents. Pregnant women with previous UTI had a higher recurrence risk (OR=10.8; p<0.05). The antibiotics most commonly used during hospitalization were ampicillin and cefazolin. Change of therapeutic agent due to bacterial resistance occurred in 11.9% of patients who took cefazolin and in 20% of patients who took ampicillin (OR=5.5; p<0.05). The rate of gestational complications was the same for both treatments. There was no difference in mean number of days of hospitalization between the treatments. CONCLUSION: In the studied population ampicillin showed a higher rate of bacterial resistance than cefazolin, requiring a larger number of treatment regimen exchanges, without resulting in differences in clinical outcome or time of hospitalization.

Late presentation of Alport posttransplantation anti-glomerular basement membrane disease.

We describe a female patient with Alport disease who developed antiglomerular basement membrane nephritis late after kidney transplantation during the treatment of an acute bacterial pyelonephritis and discuss the potential role of the infection as a trigger for the development of this nephritis.
