Previous issue date: 2012-05-17 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis complex species, which infect the exposed individuals, initiate an immune response with production of several cytokines, among them interferon-gamma (IFN-gamma), which is crucial for activation of cellular immune response against TB bacillus. This cytokine has been extensively studied as a possible biomarker for diagnosis of TB. In this work, we analyzed the levels of IFN-gamma in response to in vitro stimulation with ESAT-6, CFP10 and TB7.7, by QuantiFERON ®-TB Gold (In-tube method) (QTF-IT) in 155 participants: 47 patients confirmed pulmonary TB (patient group), 49 direct contacts (group contact), and 59 individuals without history or contact with TB (control group). The levels of IFN-gamma were different among the groups (p=0.0001); the highest level was observed in the patients group (median=1.43 IU/mL). In contacts group, 20/49 (40.8%) subjects were positive for the QTF-IT (median = 0.26 IU / mL), and among these positive contacts 14/20 (70.0%) exhibited high levels of IFN-gamma, (≥ 1.05 IU/mL). The performance testing of TB patients versus controls, resulted in 80.9% sensitivity (95% CI = 69.6% to 92.1%) and 93.2% specificity (95% CI = 86.8 % to 99.6%), but when the results of contacts and control group were combined, the specificity decreased to 77.8% (95% CI = 69.9% to 85.6%). Thus, according to our data, there is a distinctive profile of IFN-gamma, with higher levels in the patients group. The QTF-IT positive in contacts, especially those with high levels of IFN-gamma, should be monitored, especially those with high levels of IFN-gamma. This result may be a risk factor for developing TB disease. In addition, the QTF-IT, properly executed, can be useful in endemic areas for the diagnosis of latent and active TB (infection) when evaluated with other routine tests. / A Tuberculose (TB) é uma doença infecciosa causada por espécies do complexo Mycobacterium tuberculosis, que ao infectar os indivíduos expostos, iniciam uma resposta imunológica com produção de várias citocinas, dentre elas o Interferon-gama (IFN-gama), que é crucial para ativação da resposta imune celular contra o bacilo da TB. Esta citocina tem sido amplamente estudada como um possível biomarcador para auxiliar no diagnóstico da TB. Neste trabalho foram analisados as concentrações de IFN-gama em resposta a estímulos in vitro com ESAT-6, CFP10 e TB7.7, utilizando o QuantiFERON®-TB Gold (In-tube method) (QTF-IT), em 155 participantes, sendo: 47 pacientes com TB pulmonar confirmada (grupo paciente), 49 contatos de pacientes com TB pulmonar (grupo contato), e 59 indivíduos sem história e/ou contato com TB (grupo controle). As concentrações de IFN-gama foram diferentes entre os grupos avaliados (p=0,0001), sendo mais elevado nos pacientes com TB (Mediana = 1.43 UI/mL). Dos contatos diretos, 20/49 (40,8%) foram positivos para o QTF-IT (Mediana=0,26 UI/mL), e destes 14/20 (70,0%) apresentaram níveis elevados de IFN-gama, superior à 1,05 UI/mL. O desempenho do teste relacionando os pacientes de TB como os doentes e os controles como sadios, resultou em 80,9% de sensibilidade (IC 95% = 69,6% a 92,1%) e 93,2% de especificidade (IC 95% = 86,8% a 99,6%), mas quando os resultados dos contatos diretos foram adicionados aos controles, a especificidade reduziu para 77,8% (IC 95% = 69,9% a 85,6%). Concluiu-se que há um perfil diferenciado na produção de IFN-gama, com níveis mais elevados nos pacientes de TB ativa, e que os contatos positivos para o QTF-IT, principalmente, aqueles com altas concentrações de IFN-gama, devem ser monitorados, considerando que o perfil ou concentração elevado desta citocina, pode ser um fator de risco para o desenvolvimento da TB doença. Além disso, o QTF-IT, executado corretamente, pode ser útil em áreas endêmicas para auxiliar no diagnóstico da TB latente (infecção) e ativa, quando avaliados com outros exames de rotina.
