Protracted, but not acute, hepatitis A virus infection is strongly associated with HLA‐DRB1*1301, a marker for pediatric autoimmune hepatitis
Leonardo Fainboim, Maria Cristina Cañero Velasco, Cintia Y. Marcos, Mirta Ciocca, Adriana Roy, Graciela Theiler, Monica Capucchio, Silvia Nuncifora, Livio Sala, Marta Zelazko – 30 December 2003 – HLA alleles are known to be associated with susceptibility to develop autoimmune hepatitis (AH), and hepatitis A virus (HAV) infection is postulated as a putative trigger for AH. We investigated whether HLA may influence the outcome of the HAV infection by studying 67 children with self‐limited and 39 children with protracted forms of this infection.
