Analysis of Immunogenetic Factors in Idiosyncratic Drug-induced Liver Injury in the Pediatric Population.

Objectives: Idiosyncratic drug-induced liver injury is a multifactorial complex disease, in which the toxic potential of the drug, together with genetic and acquired factors and deficiencies in adaptive processes, which limit the extent of damage, can determine susceptibility, and make individuals unique in their development of hepatotoxicity. The aim of the present study is to analyse the genetic factors (human leukocyte antigen [HLA], cytokine polymorphisms, and killer cell immunoglobulin-like receptor [KIR] genotype) of children who experience an episode of drug-induced liver injury.

Patients And Methods: Prospective multicentre case-control study.
