RNA Expression Profiling of CD8+ T Cell-Enriched Peripheral Blood Mononuclear Cells from Potentiated Sulfonamide-Treated Patients with a Range of Lymphocyte Cytotoxicity Phenotypes

Hypersensitivity reactions are rare, but potentially severe adverse effects of sulfonamide antibiotics. Increased in vitro toxicity of lymphocytes, primarily CD8+ T cells, to sulfonamide drug metabolites as been proposed as a marker for sulfonamide hypersensitivity, but the mechanisms underlying this marker are unknown.
