“…The study of household contacts of TB cases is of essential importance to the programs for combat and control of tuberculosis, in other words, the epidemiologic surveillance of household contacts as a means for early diagnosis of TB cases and the decrease of the spread of the disease [103]. …”

Host immune response against Mycobacterium tuberculosis is mediated by cellular immunity, in which cytokines and Th1 cells play a critical role. In the process of control of the infection by mycobacteria, TNF-alpha seems to have a primordial function. This cytokine acts in synergy with IFN-gamma, stimulating the production of reactive nitrogen intermediates (RNIs), thus mediating the tuberculostatic function of macrophages, and also stimulating the migration of immune cells to the infection site, contributing to granuloma formation, which controls the disease progression. IFN-gamma is the main cytokine involved in the immune response against mycobacteria, and its major function is the activation of macrophages, allowing them to exert its microbicidal role functions. Different from TNF-alpha and IFN-gamma, IL-10 is considered primarily an inhibitory cytokine, important to an adequate balance between inflammatory and immunopathologic responses. The increase in IL-10 levels seems to support the survival of mycobacteria in the host. Although there is not yet conclusive studies concerning a clear dichotomy between Th1 and Th2 responses, involving protective immunity and susceptibility to the disease, respectively, we can suggest that the knowledge about this responses based on the prevailing cytokine profile can help to elucidate the immune response related to the protection against M. tuberculosis.

“…The active search for RSs represents the initial strategy for detecting new TB cases and the first among the various control actions necessary for the continuity of care (9,11) . This is an activity that must be incorporated by the professionals of the health teams through the systematic search for suspected cases, in the spontaneous demand for health services, during domicile visits, in specific groups (people living in closed institutions) and in community events (educational campaigns) (15) .…”

This study sought to analyze the actions of an active search for respiratory symptomatics (RSs) in the control of tuberculosis (TB) enfermagem e agentes indígenas de saúde. Utilizou-se a técnica de grupo focal como instrumento de coleta de dados, cujo tratamento fundamentou-se na técnica de análise de discurso. Evidenciaram-se debilidades de natureza operacional, relacionadas à organização do serviço de saúde local para a implantação de rotinas de diagnóstico para a TB: ausência de rotina sistematizada para a busca de SR, dificuldades na organização do material para exame bacteriológico, abordagem inadequada ao paciente, durante a coleta do escarro, e insuficiente capacitação profissional. Julga-se necessário melhorar a organização dos serviços para a detecção precoce dos casos de TB, no cenário indígena local.Descritores: Tuberculose; População Indígena; Serviços de Saúde.La búsqueda activa de sintomáticos respiratorios para el control de la tuberculosis en el escenario indígena Potiguara, estado de Paraíba, BrasilEste estudio analiza las acciones de la búsqueda activa de sintomáticos respiratorios (SR) para el control de la tuberculosis (TB) en el Distrito Sanitario Especial Indígena Potiguara, en Paraíba, Brasil, en el período de mayo a junio de 2007. Después de aprobado por el Comité de Ética en Investigación, fueron reunidos 23 profesionales, entre médicos, enfermeros, técnicos de enfermería y agentes indígenas de la salud. Se utilizó la técnica de grupo focal como instrumento de recolección de datos, cuyo tratamiento se fundamentó en la técnica de análisis de discurso. Se evidenciaron debilidades de naturaleza operacional, relacionadas a la organización del servicio de salud local para la implantación de rutinas de diagnóstico para la TB, que fueron: ausencia de una rutina sistematizada para la búsqueda de SR, dificultades en la organización del material para examen bacteriológico, abordaje inadecuado al paciente durante la recolección del esputo, e insuficiente capacitación profesional. Se juzga necesario mejorar la organización de los servicios para la detección precoz de los casos de TB en el escenario indígena local.
