Urinary tract infections (UTIs) are a common and potentially serious bacterial infection of childhood. History and examination findings can be non-specific, so a urine sample is required to diagnose UTI. Sample collection in young precontinent children can be challenging. Bedside dipstick tests are useful for screening, but urine culture is required for diagnostic confirmation. Antibiotic therapy must be guided by local guidelines due to increasing antibiotic resistance. Duration of therapy and indications for imaging remain controversial topics and guidelines lack consensus. This article presents an overview of paediatric UTI diagnosis and management, with highlights of recent advances and evidence updates.

Introduction.The main treatment component of asymptomatic bacteriuria, acute cystitis and pyelonephritis in pregnant women is antibiotic therapy, which in many patients is prescribed empirically. For successful selection of the drug, it is necessary to know both the structure of pathogens and the current profile of their antibiotic resistance.Purpose of research.The study of species composition and resistance to antibiotics of bacteria that cause urinary tract infections (UTIs) in pregnant women in the Moscow RegionMaterials and methods.The study included 104 pregnant women with uncomplicated UTIs who were observed and treated at the Lapino Clinical Hospital between 2016 and 2017. The material for bacteriological studies was the midstream portion of urine or urine collected by a catheter.Results.90 patients had asymptomatic bacteriuria, 10 had acute cystitis, and 4 had acute gestational pyelonephritis. The structure of the pathogens of UTI is presented: E. coli, Enterococcus faecalis, Klebsiella pneumoniae, Proteus spp., Staphylococcus spp., Streptococcus spp., Enterobacter cloacae. The most frequently detected pathogens were E. coli (67.3%) and E. faecalis (50%). Resistance rate of E.coli strains more than 20% was detected to ampicillin (36.4%), amoxicillin / clavulanate (23.2%), trimethoprim / sulfamethoxazole (27.4%), nalidixic acid (20.7%), cephalosporins 2 and 3 generation (respectively, 25.7% and 24.3%). Resistance rate more than 20% in Enterobacteriaceae family strains was detected to trimethoprim/sulfamethoxazole (24.4%), nalidixic acid (20.7%), cephalosporins 2 generations (21.7%). Antibiotic resistance of E.coli and other Enterobacteriaceae family taxons less than 10% was noted only with respect to carbapenems (0%) and fosfomycin (1.5% and 3.5%, respectively).Conclusions.It is expedient to use the obtained data on the composition and sensitivity profile of uropathogens in UTIs in pregnant women when choosing starting empirical antibiotic therapy. Disclosure: The study did not have sponsorship.

AbstractBackgroundUrinary tract infections (UTIs) are common in general practice, and antibiotic resistance is often seen. Urine cultures are advised by the Dutch national UTI guideline for patients at high risk of UTI complications. Prudent use of antibiotics and taking into account national guidelines and urine culture results are important to combat antibiotic resistance in general practice.AimTo identify subgroups of UTI patients in which the use of urine cultures and antibiotic prescriptions deviates from the national guidelines.MethodsWe investigated associations of several characteristics with urine culture orders in patients with UTI in 2015 from seven Dutch general practices (n=1295). These included subgroups at risk for UTI complications, comorbidities, age and history of UTI recurrence. In addition, we assessed the level of adherence to the guideline for antibiotic prescriptions in subgroups at risks for UTI complications.FindingsUrine cultures were ordered in 17% (n=221) of patients, more frequently in high-risk patients (32%) than in low-risk patients (7%), for UTI complications (OR=6.4; 95% CI 4.6–9.0). In low-risk patients, 91% received antibiotics that were recommended in the guideline. For high-risk patients this percentage ranged widely, and was particularly low in the risk groups with signs of tissue invasion (29–50%). Diagnostic and therapeutic adequacy can still be improved by increasing the adherence to the guideline in UTI patients at high risk for complications. This may contribute to containing antibiotic resistance in UTI by ordering urine cultures and use the results to adjust prescriptions to antibiotic susceptibility of the uropathogen.

Abstract Background With the Joint Commission standards targeting ambulatory settings serving as a catalyst, we designed a quality improvement (QI) project was designed to evaluate the existing management and prescribing patterns for urinary tract infections (UTI) in the Walter Reed National Military Medical Center (WRNMMC) Emergency Department (ED) in order to identify targets for ASP intervention. Methods This was a Pharmacist-driven, prospective, QI project conducted over a 3-month period. The clinical presentations and microbiological data of uncomplicated cystitis and pyelonephritis cases managed in the ED were reviewed. Within 24-72 hours of ED discharge, recommendations were relayed to both patients and ED staff. Diagnostic criteria and management concordant with established clinical guidelines were assessed. Inclusion criteria included age ≥ 18, admission status, urine culture and antibiotics for UTI or pyelonephritis. Results A daily urinalysis (UA) report identified 1781 ED encounters of which 117 cases met inclusion criteria. Nitrofurantoin was most prescribed empirically at 39.3% followed by a cephalosporin (23.1%) or a fluoroquinolone (19.7%), accounting for 32% of inappropriate empiric antibiotic selection. Cases were identified with inappropriate duration of therapy (22.2%), dosage (9.4%), and drug-bug mismatch (9.4%). Nearly 38% of cases required intervention to discontinue (32.5%) or initiate new antibiotics (3.4%). Diagnostic concordance was defined as having positive urinary symptoms, clinically significant UA and positive urine culture. This was only observed in 37.6% of all cases, of which only 43.2% were treated with a guideline concordant empiric regimen, dosage and duration of therapy. Although not included in the final analysis, it was noted 916 urine culture results were ordered where 70% were not associated with genitourinary complaints or sepsis. Conclusion Despite guidelines for UTI management, considerable practice discordance was found in the ED. Multiple Pharmacist targeted interventions were identified. Prioritized areas for ED provider education include first-line therapy, treatment duration, and diagnostic stewardship. This QI project has potential for optimizing prescribing practices in Military Health System ambulatory settings. Disclosures All Authors: No reported disclosures

Introdução: As infecções do trato urinário (ITU), de origem comunitária, são diagnósticos muito prevalentes a nível ambulatorial, sendo uma grande causa de uso de antibioticoterapia. Seus agentes etiológicos mais prevalentes são os bacilos gram-negativos da família Enterobacteriaceae, em especial a Escherichia coli (E. coli). Visando este agente, as terapias antimicrobianas empíricas mais utilizadas no Brasil são o sulfametoxazol-trimetoprim, quinolonas, cefalosporinas de 1º e 2º geração, amoxicilina e nitrofurantoína. Objetivos: Tendo em vista o aumento da antibioticorresistência a estes medicamentos, demonstrado na literatura médica mundial, e a importância do conhecimento deste dado pela comunidade médica local, este artigo pretende traçar o perfil de resistência às quinolonas e ao sulfametoxazol-trimetoprim pelas cepas de E. coli isoladas de uroculturas de ITU comunitária, encaminhadas para um laboratório de análises clínicas, de uma cidade do sul de Minas Gerais, no período de 2010 a 2014. Métodos: Estudo descritivo e retrospectivo por meio de pesquisa em banco de dados, no período de 2010 a 2014. Foram realizadas análises de urocultura e antibiograma, com cálculo estatístico utilizando-se o teste qui-quadrado. Resultados: Foram obtidas 14870 uroculturas, tendo crescimento bacteriano maior que 105 unidades formadoras de colônia (UFC) em 3073 amostras, das quais 2203 foram cepas de E. coli e 870 de outras bactérias. A taxa global de resistência nos 5 anos de todos os antibióticos foi de 24,46%, sendo que a de sulfametoxazol-trimetoprim em específico foi de 19,65% e a do grupo quinolonas, 19,2%. Observou-se aumento da resistência ao longo dos 5 anos (p<0,0001) e que é mais incidente em mulheres e em maiores de 65 anos. Conclusão: As taxas de resistência às quinolonas e ao sulfametoxazol-trimetoprim atingiram níveis próximos do limiar permitido para seu uso empírico. A idade e o gênero mostram-se fatores importantes na antibioticorresistência, especialmente nos maiores de 65 anos e no gênero feminino.Palavras-chave: Infecções urinárias; Farmacorresistência bacteriana; Infecções comunitárias adquiridas; Quinolonas; Trimetropima-sulfametoxazolABSTRACTIntroduction: Communitarian urinary tract infections are frequently diagnosed ambulatorily, and they are the most important cause for using antibiotic therapy. Its most common agents are gram-negative bacils from the enterobacteriaceae family, especially Escherichia coli (E. coli). Focusing on this bacterium, the empiric antibiotic therapies which are mostly used in Brazil are trimethoprim/sulfamethoxazole, quinolones, 1st and 2nd generation of cephalosporin, amoxicillin, and nitrofurantoin. Aims: Foreseeing the intense growth of antibiotic therapy resistance to these drugs shown in the world's medical literature and the importance of local medical community having knowledge of this data, this article proposes the research of quinolones and trimethoprim-sulfamethoxazole combination resistance to E. coli bacteria isolated in community-acquired UTI urocultures, from a clinical analysis laboratory, in the period from 2010 to 2014 in a southern city of the state of Minas Gerais. Methods: Retrospective and descriptive study by database research in the period from 2010 to 2014. Urocultures and antibiogram analysis were done, and the statistic calculous were made by using qui-square's test. Results: 14870 urocultures were studied. However, only 3073 samples had significant bacterial growth (bigger than 105CFU). From this result, 2203 were E. coli samples and 870 were from other bacteria. The global resistance in this 5 year study for all antibiotics was 24,46 %. Furthermore, trimethoprim-sulfamethoxazole combination resistance was 19,65% and the quinolones group was 19,2%. Through research, we have noticed an increasing resistance through these five years (p<0,0001), thus, having bigger incidence in woman and in people older than 65 years old. Conclusion: Antibiotic resistance rates almost reach unacceptable levels for therapeutic use. Age and gender demonstrated importance at antibiotic resistance, especially for people older than 65 years of age and the feminine gender.Keywords: Urinary tract infections; Drug resistance bacterial; Community-acquired infections; Quinolones; Trimethoprim-sulfamethoxazole
