Study title acronym
Study typeObservational study
Brief description of the studyTuberculosis represents nowadays one of the main problems in public health both in non-developed as in developed countries. The increase of the incidence of tuberculosis during the last years has been related to an increase in complications derived from its treatment, based on the use of isoniazid, rifampicin and pyrazinamide, as well as to the appearance of resistance, therapeutic failure or hepatotoxicity. In particular, hepatotoxicity due to anti-tuberculous drugs is a relevant problem for the scientific community as it results in the modification of the treatment and in liver transplantation or death in the most extreme situations.
We propose the study of a cohort of patients who initiate treatment or profilaxis with antituberculous drugs, with the aim of identifying those presenting a high risk of developing hepatotoxicity. Therefore, we propose the analysis of the serum proteomic profiles of these patients. The main goal is the identification and characterisation of biological markers which would be predictive of hepatotoxicity associated with anti-tuberculous drugs.

Additional information
We calculated that 500 patients who initiate treatment or profilaxis with antituberculous drugs would bee needed to be enrolled for the study to have a statistical power of 93% to detect 10 patients with a clinical expression of hepatotoxicity and 80 cases with alanineaminotrasnferase elevations.
