Liver biopsy is currently the only reliable method to establish nonalcoholic fatty liver disease (NAFLD) severity. However, this technique is invasive and occasionally associated with severe complications. Thus, non-invasive diagnostic markers for NAFLD are needed.

Drug-induced steatosis is a major reason for drug failure in clinical trials and post-marketing withdrawal; and therefore, predictive biomarkers are essential. These could be particularly relevant in non-alcoholic fatty liver disease (NAFLD), where most patients show features of the metabolic syndrome and are prescribed with combined chronic therapies, which can contribute to fatty liver. However, specific biomarkers to assess the contribution of drugs to NAFLD are lacking.

Multiple analytical methods are required to comprehensively assess oxidative homeostasis and specific damage to macromolecules. Our aim was to develop a straightforward strategy for the fast assessment of global oxidative status and specific damage to DNA, proteins, and lipids. To this end, an analytical method, based on ultra-performance liquid chromatography coupled to mass spectrometry (UPLC-MS/MS), was developed and validated for the quantification of 16 oxidative stress (OS) biomarkers.

Objectives: The identification of prognostic factors of easy application in clinical practice can improve the diagnostic and therapeutic decision making process in upper gastrointestinal bleeding (UGB). The present study estimates the capacity to predict an unfavorable clinical course (mortality, unstable bleeding, and/or interventional therapy) on the basis of the preendoscopic and endoscopic clinical analytical findings in patients with UGB owing to peptic ulcer.

Method: A retrospective cohort study was made of 473 adult patients seen in the Emergency Service of a District Hospital, and diagnosed with UGB secondary to gastroduodenal ulcer.
