Resumo: Introduction: The emergence of β-lactamases producing bacteria is a problem worldwide, with increasing importance in communityacquired infections, especially in urinary tract infections. Data regarding the use of non-carbapenem antimicrobials in these infections are scarce. The aim of this study was to analyse the treatment and outcome of urinary tract infections caused by community-acquired β-lactamase-producing bacteria in children.Material and Methods: Retrospective study performed in a level III paediatric hospital, between June 2007 and December 2017. All children with β-lactamase-producing Enterobacteriaceae identified in aseptically collected urine culture were included.Results: A total of 175 urinary infections caused by β-lactamases producing bacteria were diagnosed, 34 (19%) were community-acquired: 25 Escherichia coli (74%), 4 Klebsiella pneumoniae (12%), 4 Proteus mirabilis (12%) and 1 Proteus vulgaris (3%). In 30 (88%) cases, it was the first urinary infection. After identification of the microorganism and antimicrobial susceptibility, 33 (97%) children were re-evaluated and 24 (71%) had a repeat urine culture, which was positive in three (13%). In six (18%) cases, antibiotic treatment was modified. Four (12%) children had another UTI in the following month. In 30 (88%) children, imaging was carried out, with no nephrourological malformations detected.Discussion: In the last decade, about 20% of urinary infections caused by β-lactamase-producing Enterobacteriaceae were community-acquired with a relatively stable number of cases over the years. No nephro-urological malformations were identified in these children.Conclusion: Although the number of cases is small, the clinical and microbiological outcomes showed that most were successfully treated with non-carbapenem antibiotics, with low recurrence of new episodes of urinary tract infections.

Os dados pediátricos de utilização de antimicrobianos não carbapenemos nestas infeções são escassos. O objetivo do estudo foi analisar a terapêutica antibiótica instituída nas infeções urinárias causadas por estes agentes, assim como a evolução clínica e laboratorial.Material e Métodos: Estudo retrospetivo efetuado num hospital pediátrico entre junho de 2007 e dezembro de 2017. Foram incluídas todas as crianças com urocultura positiva para Enterobacteriaceae produtoras de β-lactamases.Resultados: Foram diagnosticadas 175 infeções urinárias causadas por Enterobacteriaceae produtoras de β-lactamases, das quais 34 (19%) foram adquiridas na comunidade: 25 Escherichia coli (74%), 4 Klebsiella pneumoniae (12%), 4 Proteus mirabilis (12%) e 1 Proteus vulgaris (3%). Em 30 (88%) episódios tratou-se da primeira infeção urinária. Após conhecimento do microrganismo e suas suscetibilidades, 33 (97%) crianças foram reavaliadas e 24 (71%) repetiram urocultura, que foi positiva em três (13%). Em seis (18%) casos foi alterado o antimicrobiano. No mês subsequente, quatro (12%) crianças tiveram nova infeção urinária e 30 (88%) crianças realizaram investigação imagiológica, sem deteção de malformações nefro-urológicas.Discussão: Na última década, cerca de 20% das infeções urinárias causadas por Enterobacteriaceae produtoras de β-lactamases foram adquiridas na comunidade, com um número relativamente estável ao longo dos anos. Estas crianças não apresentavam malformações nefro-urológicas.Conclusão: Embora o número de casos seja pequeno, a evolução clínica e microbiológica mostrou que a maioria foi tratada com sucesso com antimicrobianos não carbapenemos, com baixa ocorrência de novos episódios.Ordem dos Médicos2020-07-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/12338oai:ojs.www.actamedicaportuguesa.com:article/12338Acta Médica Portuguesa; Vol. 33 No. 7-8 (2020): July-August; 466-474Acta Médica Portuguesa; Vol. 33 N.º 7-8 (2020): Julho-Agosto; 466-4741646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/12338https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/12338/5845https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/12338/6706https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/12338/11452https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/12338/12098Direitos de Autor (c) 2020 Acta Médica Portuguesainfo:eu-repo/semantics/openAccessSimões, AnaLima, MargaridaBrett, AnaQueiroz, CarolinaChaves, CatarinaOliveira, HenriqueJanuário, LuísRodrigues, Fernanda2022-12-20T11:06:36Zoai:ojs.www.actamedicaportuguesa.com:article/12338Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:20:10.711900Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
