ABSTRACT
Advances in diagnostic research are moving towards methods whereby the periodontal risk can be identified and quantified by objective measures using biomarkers. Patients with periodontitis may have elevated circulating levels of specific inflammatory markers that can be correlated to the severity of the disease. The purpose of this study was to evaluate whether differences in the serum levels of inflammatory biomarkers are differentially expressed in healthy and periodontitis patients. Twenty-five patients (8 healthy patients and 17 chronic periodontitis patients) were enrolled in the study. A 15 mL blood sample was used for identification of the inflammatory markers, with a human inflammatory flow cytometry multiplex assay. Among 24 assessed cytokines, only 3 (RANTES, MIG and Eotaxin) were statistically different between groups (p<0.05). In conclusion, some of the selected markers of inflammation are differentially expressed in healthy and periodontitis patients. Cytokine profile analysis may be further explored to distinguish the periodontitis patients from the ones free of disease and also to be used as a measure of risk. The present data, however, are limited and larger sample size studies are required to validate the findings of the specific biomarkers.
RESUMO
Avanços no diagnóstico da doença periodontal levam a métodos nos quais o risco e atividade da doença periodontal podem ser identificados e quantificados por biomarcadores. Pacientes com periodontite podem apresentar elevados níveis circulatórios de marcadores inflamatórios específicos que podem ser correlacionados com a severidade da doença. Portanto, o objetivo desse estudo foi avaliar as diferenças nos níveis séricos de biomarcadores inflamatórios em pacientes saudáveis e com doença periodontal. Foram incluídos no estudo 25 pacientes (8 saudáveis e 17 com periodontite crônica). Uma amostra de 15 mL de sangue foi obtida para identificar os marcadores inflamatórios simultaneamente utilizando Array de proteínas através de citometria de fluxo. De 24 citocinas inflamatórias analisadas, apenas 3 (RANTES, MIG e Eotaxina) apresentaram diferenças estatisticamente significantes (p<0,05) entre os dois grupos. Conclui-se que alguns marcadores inflamatórios selecionados apresentam diferença de concentração em pacientes com periodontite e saudáveis. A análise do perfil de citocinas pode ser utilizada tanto para distinguir pacientes periodontais de pacientes saudáveis, como para medir o risco à doença. Contudo, mais estudos com número maior de amostras são necessários para validar os achados sobre os biomarcadores específicos.
