Most adverse cutaneous drug reactions (ACDR) are mediated by delayed hypersensitivity (dh) with lymphocyte recruitment and inflammatory cytokines release, including tumour necrosis factor alpha (TNFalpha). Polymorphisms in the TNFalpha gene, such as the infrequent allele TNF2, predispose to certain inflammatory entities and enhance TNFalpha production. The incidence of the TNF2 allele is increased in British patients with severe ACDR, suggesting TNFalpha as a major contributor in the pathogenesis of ACDR.
