Antituberculosis drug resistance in isolates of Mycobacterium tuberculosis complex in southeast Spain.

Objectives: The aim of this study was to determine resistance to antituberculosis (anti-TB) drugs in Mycobacterium tuberculosis complex isolates from patients diagnosed with Tuberculosis (TB) in southeast Spain and to study related epidemiological factors.

Methods: This retrospective study analysed 5-year data (2012-2016) obtained in southeast Spain for a total equivalent population of 1 735 608 inhabitants. Clinical samples were examined from 557 patients with suspected pulmonary TB (n=470; 84.

The value of serum aspartate aminotransferase and gamma-glutamyl transpetidase as biomarkers in hepatotoxicity.

Background & Aims: The current definition of the pattern of liver injury in hepatotoxicity (DILI) is given by the R (ratio) value, dividing alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in upper limits of normal at DILI onset. We aimed to explore the validity of using aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT) as biomarkers of hepatocelullar and cholestatic damage, respectively, when calculating the R value.

Methods: Clinical, laboratory and histological data from 588 DILI episodes included in the Spanish DILI Registry were analyzed.
