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.

Review Case Reports
Periodic generalized edema following COVID-19 infection.
The unprecedented impact and sequelae of COVID-19 infection are not yet fully understood, and better understanding of the pathophysiology of these infections is needed. Endothelial dysfunction might be common sequelae associated with COVID-19, and increased inflammatory responses, oxidative stress, proinflammatory cytokines, and impaired mitochondrial function also contribute to the pathophysiology of post COVID-19 medical disorders. ⋯ Here, we report a case of adult patient with 2 episodes of systemic capillary leak syndrome following prior COVID-19 infection. This patient had a transient response to intravenous IgG.
