Abstract(s)
A estirpe híper-virulenta Klebsiella pneumoniae serotipo K1 é responsável por uma síndrome invasiva infeciosa, caracterizada por abcessos hepáticos com manifestações extra-hepáticas. Inicialmente identificada em Taiwan, tem aumentado significativamente em vários países da Ásia, e mais recentemente na Europa e América do Norte, conferindo a esta entidade um caracter emergente e global. Os autores apresentam o caso clinico de uma mulher de 64 anos, caucasiana, portuguesa, sem antecedentes pessoais ou epidemiológicos como viagens ou exposição a produtos asiáticos, na qual foi diagnosticada, abcesso hepático piogénico complicado de derrame pleural por esta estirpe híper-virulenta. Após conhecimento do diagnóstico e instituição de terapêutica antibiótica combinada com drenagem percutânea, foi possível a resolução do caso clínico com sucesso. Este caso permitiu a identificação do primeiro caso de síndroma invasiva infeciosa, por Klebsiella pneumoniae do clone híper-virulento ST23 documentado em Portugal.
The hypervirulent K1 serotype Klebsiella pneumoniae is responsible for a new invasive syndrome, typically associated to hepatic abscesses with extra-hepatic complications. Initially described in Taiwan, it has significantly spread to several Asian countries and more recently to Europe and North America, thus constituting an emerging and global problem. The authors describe a case report of a 64-years-old portuguese caucasian woman without any previous diseases or epidemiological risk factors such as trips or contact with Asian products or population, diagnosed with a pyogenic liver abscess with pleural effusion caused by this hyper-virulent strain. A successful clinical cure was achieved after the etiological identification and treatment with antimicrobial therapy combined with catheter drainage. This is the first identification of hypervirulent Klebsiella pneumonia ST 23 clone in Portugal in the context of an invasive syndrome.
