Interleucina-12 em crianças com sepse e choque séptico / Interleukin-12 in children with sepsis and septic shock

RESUMO

OBJETIVO: Examinar o comportamento da interleucina-12 e verificar se pode ser utilizada para diferenciar condições sépticas em crianças. MÉTODOS: Foram inscritas, de forma prospectiva, entre janeiro de 2004 e dezembro de 2005, crianças com idades de 28 dias a 14 anos, subdivididas nos grupos sepse (SG; n=47) e choque séptico (SSG; n=43). A interleucina-12 foi avaliada quando da admissão (T0) e 12 horas mais tarde (T12). A gravidade da doença foi avaliada utilizando o escore PRISM. RESULTADOS: A interleucina-12 não diferenciou crianças com sepse das com choque séptico quando da admissão [SSG: 0,24 (0-22,64)=SG: 1,23 (0-511,6); p=0,135)] e na avaliação T12 [SG: 6,11 (0-230,5)=SSG: 1,32 (0-61,0); p=0,1239)]. Na comparação entre os momentos, não foi observada diferença estatística para SG [SG, T0: 1,23 (0-511,6)=T12: 6,11 (0-230,5); p=0,075]. Entretanto, em casos de SSG, a interleucina-12 aumentou entre as avaliações T0 e T12 [SSG, T0: 0,24 (0-226,4)

ABSTRACT

OBJECTIVE: To examine the behavior of interleukin-12 and verify whether it can be used to differentiate septic conditions in children. METHODS: Septic children aged between 28 days and 14 years, prospectively enrolled from 01/2004 to 12/2005, were divided into sepsis (SG; n=47) and septic shock (SSG; n=43) groups. Interleukin-12 levels were measured at admission (T0) and 12 hours later (T12). Disease severity was assessed by the PRISM score. RESULTS: Interleukin-12 levels did not differentiate children with sepsis from those with septic shock at admission [SSG: 0.24 (0-226.4)=SG: 1.23 (0-511.6); p=0.135)] and T12 [SG: 6.11 (0-230.5)=SSG: 1.32 (0-61.0); p=0.1239)]. Comparing time points, no significant difference was observed in the SG [SG, T0: 1.23 (0-511.6)=T12: 6.11 (0-230.5); p=0.075]. In SSG however, interleukin-12 increased from T0 to T12 (SSG, T0: 0.24 (0-226.4)
