Previous issue date: 2016-01-13 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Objective: To compare the ferritin levels in the cerebrospinal fluid (CSF) of children with clinical suspicion bacterial meningitis, viral and non-meningitis cases. Methods: A cohort, historical and contemporary study was conducted in two tertiaries hospitals in the southern Brazil. All children included were between 28 days and 12 years old with suspected acute meningitis. Ferritin levels in the CSF were measured in the period between 2005 and 2015 and they were compared among patients with bacterial meningitis, viral meningitis and non-meningitis. Results: Eighty one patients were included. The median age was 24 (IQR8.0-69.0) months. It was identified 32 patients with viral meningitis (39%), 23 with bacterial (28%) and 26 as non-meningitis (32%). Demographic and clinical characteristics at admission were similar between groups. The median CSF ferritin was 52.8 (IQR30.7-103.0) for the bacterial meningitis group, 4.1 (IQR3.0-6.7) for the viral group and 4.0 (IQR2.0-2.3) for the non-meningitis group (p<0.001). When compared in pairs, bacterial meningitis was distinguished from viral meningitis (p <0.001) and non-meningitis (p <0.001). However, ferritin levels failed to distinguish viral meningitis from non-meningitis. The CSF ferritin, with a cut-off value of 16 ng/ml, had 100% sensitivity and 98.3% specificity for bacterial meningitis. Conclusion: CSF ferritin was shown to be an excellent marker for identifying and discriminating bacterial meningitis in children with clinical symptoms of this disease. / Objetivo: Comparar os n?veis de ferritina no l?quido cefalorraquidiano (LCR) de crian?as com suspeita cl?nica de meningite bacteriana, viral e n?o meningite. Metodologia: Estudo de coorte, hist?rico e contempor?neo realizado em dois hospitais terci?rios do Sul do Brasil. Foram inclu?das todas as crian?as entre 28 dias e 12 anos de vida, que se apresentaram com suspeita cl?nica de meningite aguda, em que foram dosados os n?veis de ferritina no LCR no per?odo entre 2005 e 2015. Foram comparados os n?veis de ferritina no LCR dos pacientes com meningite viral, meningite bacteriana e n?o meningite. Resultados: Foram inclu?dos 81 pacientes. A mediana da idade foi 24 (IQR8,0-69,0) meses. Identificou-se 32 pacientes com meningite viral (39%), 23 com bacteriana (28%) e 26 com n?o meningite (32%). As caracter?sticas demogr?ficas e cl?nicas na interna??o foram semelhantes entre os grupos. A mediana da ferritina no LCR foi 52,8 (IQR30,7-103,0) para o grupo da meningite bacteriana, 4,1 (IQR3,0-6,7) para o grupo viral e 4,0 (IQR2,0-2,3) para o grupo n?o meningite (p<0,001). Quando comparados os pares, distinguiu-se meningite bacteriana da meningite viral (p<0,001) e da n?o meningite (p<0,001). Entretanto, n?o conseguiu distinguir meningite viral da n?o meningite. A ferritina no LCR, com um ponto de corte de 16ng/ml, mostrou uma sensibilidade de 100% e uma especificidade de 98,3% para o diagn?stico de meningite bacteriana. Conclus?o: A ferritina no LCR mostrou-se um marcador excelente para identificar e discriminar meningite bacteriana em crian?as com sintomas cl?nicos desta doen?a.
