OBJETIVOS: Estudar o comportamento da procalcitonina e verificar se é capaz de diferenciar crianças com quadros sépticos. MÉTODOS: Crianças de 28 dias a 14 anos de idade, admitidas de 01/2004 a 12/2005 na unidade de tratamento intensivo pediátrica da UNESP com sepse ou choque séptico, foram incluídas prospectivamente. Dois grupos foram constituídos: grupo sepse (GS; n = 47) e grupo choque séptico (GCS; n = 43). Procalcitonina foi medida à admissão (T0) e depois de 12 h (T12h), e os resultados apresentados em classes: 0,5 a 2 a 10 = choque séptico. RESULTADOS: No T0, foi maior a freqüência de pacientes do GCS na classe mais alta de procalcitonina, comparada às crianças do GS [GCS: 30 (69,7%) > GS: 14 (29,8%); p 10 = 69,7%; > 2 a 0,5 a OBJECTIVES: To study the behavior of procalcitonin and to verify whether it can be used to differentiate children with septic conditions. METHODS: Children were enrolled prospectively from among those aged 28 days to 14 years, admitted between January 2004 and December 2005 to the pediatric intensive care unit at Universidade Estadual Paulista UNESP with sepsis or septic shock. The children were classified as belonging to one of two groups: the sepsis group (SG; n = 47) and the septic shock group (SSG; n = 43). Procalcitonin was measured at admission (T0) and again 12 hours later (T12h), and the results classed as: 0.5 to 2 to 10 = septic shock. RESULTS: At T0 there was a greater proportion of SSG patients than SG patients in the highest PCT class [SSG: 30 (69.7%) > SG: 14 (29.8%); p 10 = 69.7%; > 2 to 0.5 to < 2 = 11.6%; < 0.5 = 0.0%; p < 0.05). The behavior of procalcitonin at T12h was similar to at T0. The pediatric risk of mortality (PRISM) scores for the SSG patients in the highest procalcitonin class were more elevated than for children in the SG [SSG: 35.15 (40.5-28.7) vs. SG: 18.6 (21.4-10.2); p < 0.05]. CONCLUSIONS: Procalcitonin allows sepsis to be differentiated from septic shock, can be of aid when diagnosing septic conditions in children and may be related to severity.
