Update of SEPAR guideline «Diagnosis and Treatment of Drug-Resistant Tuberculosis¼. / Actualización de la normativa SEPAR «Diagnóstico y tratamiento de la tuberculosis con resistencia a fármacos¼.

New evidence and knowledge about the clinical management of drug-resistant tuberculosis (TB) in the last 3 years, makes it necessary to update the recent guideline published by SEPAR in 2017, mainly in relation to new diagnostic methods, drug classification, and regimens of treatment recommended to treat patients with isoniazid-resistance TB, rifampicin resistance TB and multidrug-resistant TB. With respect to tuberculosis diagnosis, we recommend the use of rapid molecular assays that also help to detect mutations associated with resistance. In relation to the treatment of multidrug-resistant TB we prioritize effective all-oral shorter treatment regimens including bedaquiline, a fluoroquinolone (levofloxacin or moxifloxacin), bedaquiline and linezolid, instead of the previously recommended short-course treatment with aminoglycosides and other less effective and more toxic drugs. The design of these regimens (initial schedule and changes in the regimen if necessary) should be made in accordance with drug-resistant TB experts; the treatment should be the responsibility of personnel with experience in the treatment of TB and in TB units guaranteeing the follow-up of the treatment and the management of drugs adverse effects.

Diagnóstico y tratamiento de la tuberculosis con resistencia a fármacos / Diagnosis and treatment of drug-resistant tuberculosis

En las últimas 2 décadas la tuberculosis con resistencia a fármacos se ha convertido en una amenaza y un reto para la salud pública mundial. El diagnóstico y el tratamiento de estas formas de tuberculosis es mucho más complejo, y el pronóstico empeora claramente a medida que se incrementa el patrón de las resistencias. Sin embargo, es necesario destacar cómo con el manejo clínico y programático adecuado de estos enfermos se puede conseguir la curación de una mayoría de ellos. En esta normativa se razonan las bases del diagnóstico y tratamiento de todos los pacientes afectos de tuberculosis, desde aquellos que tienen formas de la enfermedad con sensibilidad a todos los fármacos hasta aquellos que son portadores de los patrones más extensos de resistencia. Asimismo, se dan recomendaciones específicas para cada uno de estos supuestos. También se aborda el papel que ya están teniendo y pueden tener en un futuro inmediato los nuevos métodos moleculares de detección de resistencias, los esquemas acortados de tratamiento de la tuberculosis multi-farmacorresistente (TB-MDR) y los nuevos fármacos con actividad frente a Mycobacterium tuberculosis (AU)

In the last 2 decades, drug-resistant tuberculosis has become a threat and a challenge to worldwide public health. The diagnosis and treatment of these forms of tuberculosis are much more complex and prognosis clearly worsens as the resistance pattern intensifies. Nevertheless, it is important to remember that with the appropriatesystematic clinical management, most of these patients can be cured. These guidelines itemize the basis for the diagnosis and treatment of all tuberculosis patients, from those infected by strains that are sensitive to all drugs, to those who are extensively drug-resistant. Specific recommendations are given forall cases. The current and future role of new molecular methods for detecting resistance, shorter multi-drug-resistant tuberculosis regimens, and new drugs with activity against Mycobacterium tuberculosis are also addressed (AU)
