HLA and Delayed Drug-Induced Hypersensitivity.
Delayed drug allergy reactions (DDAR) are potentially fatal. Certain human leukocyte antigen (HLA) alleles have been associated with delayed allergy reactions following the administration of particular drugs. Examples are HLA-B*57:01 (abacavir), HLA-B*15:02/HLA-A*31:01 (carbamazepine), and HLA-B*58:01 (allopurinol). Based on the identification of these associations, it may now be possible to pr...
متن کاملDrug Induced Hypersensitivity and the HLA Complex
Drug-induced hypersensitivity reactions are of major concern and present a burden for national healthcare systems due to their often severe nature, high rate of hospital admissions and high mortality. They manifest with a wide range of symptoms and signs, and can be initiated by a wide range of structurally diverse chemical compounds. The pathophysiological mechanisms underlying hypersensitivit...
متن کاملHLA and pharmacogenetics of drug hypersensitivity.
Immunologically mediated drug reactions have been traditionally classified as unpredictable based on the fact that they cannot be predicted strictly on the pharmacological action of the drug. Such adverse drug reactions are associated with considerable morbidity and include severe cutaneous adverse reactions such as Stevens-Johnson syndrome/toxic epidermal necrolysis and the drug hypersensitivi...
متن کاملHuman leukocyte antigens (HLA) associated drug hypersensitivity: consequences of drug binding to HLA.
Recent publications have shown that certain human leukocyte antigen (HLA) alleles are strongly associated with hypersensitivity to particular drugs. As HLA molecules are a critical element in T-cell stimulation, it is no surprise that particular HLA alleles have a direct functional role in the pathogenesis of drug hypersensitivity. In this context, a direct interaction of the relevant drug with...
متن کاملDelayed Hypersensitivity Induced in Guinea Pigs
A delayed hypersensitivity to 7,12-dimethylbenz(a)anthracene was elicited in guinea pigs after contact sensitization. This sensitivity was characterized by its time of appearance, histology, specificity, and transfer characteristics. The reaction had its maximal dermal reactivity 24 hr after challenge, was characterized by a mononuclear cell infiltration, demonstrated immunological specificity,...
