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.

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
