Biomarkers : biochemical indicators of exposure, response, and susceptibility to chemicals

Metabolite profiles of bronchoalveolar lavage fluid (BALF) from pediatric patients with cystic fibrosis (CF) were correlated to the degree of airway inflammation using nuclear magnetic resonance spectroscopy-based metabolomics. BALF was collected from 11 children with CF during clinically indicated bronchoscopy. ⋯ Statistical analysis highlighted the most important metabolites that distinguished the high- from the low-inflammation groups. This first demonstration of metabolomics of human BALF shows that clear distinctions in the metabolic profiles can be observed between subjects experiencing high versus low inflammation and is a first step toward the goal of discovering novel biomarkers of airway inflammation.

The aim of the present study was to evaluate whether or not an elevated ischaemia-modified albumin (IMA) level provides any additional prognostic information to the validated Thrombolysis In Myocardial Infarction (TIMI) risk score in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). ⋯ IMA levels obtained at admission are a powerful indicator of short-term mortality in STEMI patients treated with primary PCI, but do not seem to be a marker that adds prognostic information to the validated STEMI TIMI risk score.
