LAGOS C, MACARENA; RODRIGUEZ D, JUAN CARLOS; PENA M, CARLOS  y  FARGA C, VICTORINO. Guidelines for the treatment of drug-susceptible tuberculosis. According to official ATS, CDC and IDSA Guidelines 2016. Rev. chil. enferm. respir. [online]. 2017, vol.33, n.1, pp.54-61. ISSN 0717-7348.

During 2016, American Thoracic Society: ATS, Centers for Disease Control and Prevention: CDC and Infectious Disease Society of America: IDSA jointly sponsored the development of Guidelines for the treatment of drug-susceptible tuberculosis using the P-I-C-O (Patient-Intervention-Comparison-Outcome) system to answer nine questions. The preferred regimen for treating adults with drug-susceptible tuberculosis, consider a 2 month intensive phase with isoniazid (INH), rifampin (RIF), pyrazinamide (PZA), and ethambutol (EMB) followed by a continuation phase of 4 months of INH and RIF For patients who have cavitation on the initial chest radiograph and have positive cultures at completion of 2 months therapy, it is recommended to extend the continuation phase to prevent relapse. EMB can be discontinued as soon as susceptibility to INH and RIF is demonstrated. The guidelines also makes recommendations for the management in different clinical situations as in patients co-infected with HIV and in extrapulmonary tuberculosis. In tuberculous pericarditis no longer is recommended the routinely use of corticosteroids together with the anti TB treatment. In the case of tuberculous meningitis it is recommended the addition of corticosteroids and to extend the continuation phase to 9-12 months.
