Adverse drug reactions can be either dose-dependent (Type A) or idiosyncratic (Type B). Type B adverse drug reactions tend to be extremely rare and difficult to predict. They are usually immune-mediated. ⋯ For many commonly prescribed drugs (such as antibiotics), the risk of developing an idiosyncratic adverse drug reaction is influenced by variability in the human leukocyte antigen (HLA) genes. Because these HLA-mediated adverse drug reactions can be lethal, there is growing interest in defining which specific drug-gene relationships might benefit from pre-emptive HLA genotyping and automated clinical decision support. This review summarizes the literature for HLA-mediated adverse reactions linked to common drugs.

Meta Analysis
Association of C-reactive protein level with adverse outcomes in patients with atrial fibrillation: A meta-analysis.
Studies on the association between C-reactive protein (CRP) level and poor outcomes have been yielded controversial results in patients with atrial fibrillation (AF). This meta-analysis sought to investigate the utility of elevated CRP level in predicting adverse outcomes in AF patients. ⋯ Elevated CRP level may be an independent predictor of all-cause mortality, stroke, and MACEs in patients with AF. CRP level at baseline can provide important prognostic information in risk classification of AF patients.
