[Ab] Resumo:The diagnosis of acute urinary tract infection and acute pyelonephritis in children is based on a set of clinical and laboratory manifestations. This paper analyzes the role of renal ultrasound study in patients with the first episode of pyelonephritis. A total of more than 1,000 children admitted to hospital with urinary tract infection were echographically examined. The most common echographic findings were pelvic wall thickening and renal enlargement. The paper also describes the rare variants of pyelonephritis: renal infiltrates and abscesses, pyelonephritis in the presence of obstructive uropathies, pyelonephritis as a cause of acute renal failure.

[Ti] Título:Role of enteroaggregative Escherichia coli virulence factors in uropathogenesis.

[Ab] Resumo:A multiresistant clonal Escherichia coli O78:H10 strain qualifying molecularly as enteroaggregative Escherichia coli (EAEC) was recently shown to be the cause of a community-acquired outbreak of urinary tract infection (UTI) in greater Copenhagen, Denmark, in 1991. This marks the first time EAEC has been associated with an extraintestinal disease outbreak. Importantly, the outbreak isolates were recovered from the urine of patients with symptomatic UTI, strongly implying urovirulence. Here, we sought to determine the uropathogenic properties of the Copenhagen outbreak strain and whether these properties are conferred by the EAEC-specific virulence factors. We demonstrated that through expression of aggregative adherence fimbriae, the principal adhesins of EAEC, the outbreak strain exhibited pronouncedly increased adherence to human bladder epithelial cells compared to prototype uropathogenic strains. Moreover, the strain was able to produce distinct biofilms on abiotic surfaces, including urethral catheters. These findings suggest that EAEC-specific virulence factors increase uropathogenicity and may have played a significant role in the ability of the strain to cause a community-acquired outbreak of UTI. Thus, inclusion of EAEC-specific virulence factors is warranted in future detection and characterization of uropathogenic E. coli.

[Ab] Resumo:Extraintestinal pathogenic Escherichia coli (ExPEC) causing urinary tract infections, bacteraemia or meningitis are characterized by a particular genetic background (phylogenetic group B2 and D) and the presence, within genetic pathogenicity islands (PAI) or plasmids, of genes encoding virulence factors involved in adhesion to epithelia, crossing of the body barriers (digestive, kidney, bloodbrain), iron uptake and resistance to the immune system. Among the many virulence factors described, two are particularly linked with a pathophysiological process: type P pili PapGII adhesin is linked with acute pyelonephritis, in the absence of abnormal flow of urine, and the K1 capsule is linked with neonatal meningitis. However, if the adhesin PapGII appears as the key factor of pyelonephritis, such that its absence in strain causing the infection is predictive of malformation or a vesico-ureteral reflux, the meningeal virulence of E. coli can not be reduced to a single virulence factor, but results from a combination of factors unique to each clone, and an imbalance between the immune defenses of the host and bacterial virulence.

[Ab] Resumo:Management of urinary tract infections (UTI) in children is at a crossroads both in regard to the diagnostic methods used, the need to detect vesico-ureteral reflux, the benefit of prophylactic antibiotics and the emergence strains of multiresistant E. coli. The Groupe de Pathologie Infectieuse Pédiatrique of French Society of Pediatrics takes position : (i) to utilize more frequently urinary dipsticks and for urinary cultures, other methods of urine sampling than bag (sample jet, urethral catheterization, supra-pubic puncture) ; (ii) do not alter the initial therapeutic proposals of the former AFSSAPS (despite the percentage of E. coli ESBL around 10 %), but now, as soon as possible to recover the result of susceptibility testing to quickly change (for effective antibiotic treatment against a resistant strain) and to increase the proportion of children receiving initial treatment with aminoglycosides monotherapy (which remains active on the majority of ESBL strains); (iii) to reduce the prescription of antibiotic prophylaxis and retrograde cystography, except in special circumstances (recurrence, major abnormalities on ultrasound).

[Ab] Resumo:The aim of the prevention of recurrent urinary tract infections in children is to reduce renal scarring, that is associated with hypertension or end-stage renal failure decades latter. However, heterogeneity of the studies prevents clear recommendations. Recent American Academy of Pediatrics meta-analysis failed to demonstrate any effectiveness of antibioprophylaxis in the prevention of recurrent febrile urinary tract infections in infants less than 2 years of age, whatever the presence or the grade of vesicoureteral reflux. Moreover, adverse events of cotrimoxazole, which is the sole antibioprophylaxis available in France, are questionable. Long term low doses of oral cephalosporins or cotrimoxazole are known to select resistant enterobacteriae, producing extended-spectrum beta-lactamases (ESBL) especially. To date, antibioprophylaxis should be discussed with urologists depending on the patient. Other preventive measures as cranberries or pre/ probiotics, are inconclusive. Surgery (or circumcision) depends on the associated uropathy. Dysfunctional elimination syndrome is frequent and has to be recognized and treated.

[Ab] Resumo:Urinary tract infections is one of the most common bacterial infections in pediatrics The increasing involvement of multiresistant bacteria including E. coli producing extended spectrum ß-lactamase (ESBL) makes its management difficult. The purpose of this article is to evaluate the state of the art and to propose ways of thinking about the management of E. coli urinary tract infection in children. The current percentage (less than 10%) of E. coli strains resistant to third generation cephalosporins and the relative efficiency of the latter, should not led to an immediate change of our protocols. Nevertheless, we should verify as soon as possible susceptibility of E. coli responsible for urinary tract infections and consider other therapeutic options for initial therapy and adaptation after obtaining antibiogram. The use of an aminoglycosid as initial treatment seems very interesting. Aminoglycosides have a very good distribution in the renal parenchyma and are still working on the majority of ESBL-producing bacteria. A rapid oral relay after 48 to 72 hours may be proposed according to the results of the susceptibility with either cotrimoxazole, cefixime, ciprofloxacin or an association cefixime-amoxicilline/clavulanate. The treatment of cystitis due to ESBL E. coli is much less problematic given the good urinary beta-lactam antibiotics diffusion. If clinical improvement occurs, even if antibiogram shows that the strain is resistant to the antibiotic prescribed, it is usually unnecessary to change treatment.

[Ab] Resumo:The diagnosis of febrile urinary tract infection in young children is difficult. Its prevalence is about 7.5 % but varies from 2 to 20 % according to the sex and age of the child. Except fever higher than 39°C for at least 48 h, no other anamnestic signs or from the clinical examination change significantly the probability of having a urinary tract infection or not. The most appropriate method of urine collection should be proposed to children clinically suspected of urinary tract infection, to avoid contamination and allow a proper diagnosis. Rapid tests (such as dipstick tests and microscopy) are useful to improve the likelihood of the diagnosis. This review focuses on the usefulness of anamnestic signs and clinical data, the way to collect urine and the performance of rapid diagnostic tests to increase or decrease the likelihood of acute urinary tract infection in children less than two years of age.

[Ab] Resumo:BACKGROUND: Anticholinergic medications and onabotulinumtoxinA are used to treat urgency urinary incontinence, but data directly comparing the two types of therapy are needed. METHODS: We performed a double-blind, double-placebo-controlled, randomized trial involving women with idiopathic urgency urinary incontinence who had five or more episodes of urgency urinary incontinence per 3-day period, as recorded in a diary. For a 6-month period, participants were randomly assigned to daily oral anticholinergic medication (solifenacin, 5 mg initially, with possible escalation to 10 mg and, if necessary, subsequent switch to trospium XR, 60 mg) plus one intradetrusor injection of saline or one intradetrusor injection of 100 U of onabotulinumtoxinA plus daily oral placebo. The primary outcome was the reduction from baseline in mean episodes of urgency urinary incontinence per day over the 6-month period, as recorded in 3-day diaries submitted monthly. Secondary outcomes included complete resolution of urgency urinary incontinence, quality of life, use of catheters, and adverse events. RESULTS: Of 249 women who underwent randomization, 247 were treated, and 241 had data available for the primary outcome analyses. The mean reduction in episodes of urgency urinary incontinence per day over the course of 6 months, from a baseline average of 5.0 per day, was 3.4 in the anticholinergic group and 3.3 in the onabotulinumtoxinA group (P=0.81). Complete resolution of urgency urinary incontinence was reported by 13% and 27% of the women, respectively (P=0.003). Quality of life improved in both groups, without significant between-group differences. The anticholinergic group had a higher rate of dry mouth (46% vs. 31%, P=0.02) but lower rates of catheter use at 2 months (0% vs. 5%, P=0.01) and urinary tract infections (13% vs. 33%, P<0.001). CONCLUSIONS: Oral anticholinergic therapy and onabotulinumtoxinA by injection were associated with similar reductions in the frequency of daily episodes of urgency urinary incontinence. The group receiving onabotulinumtoxinA was less likely to have dry mouth and more likely to have complete resolution of urgency urinary incontinence but had higher rates of transient urinary retention and urinary tract infections.

[Ab] Resumo:BACKGROUND: Catheter-associated urinary tract infection (CAUTI) is a common nosocomial device-associated infection. It is now recognized that the high infection rates were caused by the formation of biofilm on the surface of the catheters that decreases the susceptibility to antibiotics and results in anti-microbial resistance.In this study, we performed an in vitro test to explore the mechanism of biofilm formation and subsequently conducted a multi-center clinical trial to investigate the efficacy of CAUTI prevention with the application of JUC, a nanotechnology antimicrobial spray. METHODS: Siliconized latex urinary catheters were cut into fragments and sterilized by autoclaving. The sterilized sample fragments were randomly divided into the therapy and control group, whereby they were sprayed with JUC and distilled water respectively and dried before use.The experimental standard strains of Escherichia coli (E. coli) were isolated from the urine samples of patients. At 16 hours and 7 days of incubation, the samples were extracted for confocal laser scanning microscopy.A total of 1,150 patients were accrued in the clinical study. Patients were randomized according to the order of surgical treatment. The odd array of patients was assigned as the therapy group (JUC), and the even array of patients was assigned as the control group (normal saline). RESULTS: After 16 hours of culture, bacterial biofilm formed on the surface of sample fragments from the control group. In the therapy group, no bacterial biofilm formation was observed on the sample fragments. No significant increase in bacterial colony count was observed in the therapy group after 7 days of incubation.On the 7th day of catheterization, urine samples were collected for bacterial culture before extubation. Significant difference was observed in the incidence of bacteriuria between the therapy group and control group (4.52% vs. 13.04%, p < 0.001). CONCLUSIONS: In this study, the effectiveness of JUC in preventing CAUTI in a hospital setting was demonstrated in both in vitro and clinical studies.
