PG - 552-8 AB - AIMS: To determine the clinical phenotype and outcome of patients with definite type 1 autoimmune hepatitis, who lack human leukocyte antigen (HLA) DR3 and DR4, and to assess the importance of HLA DR7 and DR13. METHODS: Two hundred and seven adult patients were typed for DR3, DR4, DR7, and DR13 by DNA-based techniques. One hundred and two blood donors constituted a normal population. RESULTS: Twenty-six patients lacked DR3 and DR4 (13%). Treatment failure occurred more commonly in these individuals than in the 68 patients with DR4 (20% vs. 3%, P = 0.03), and relapse after drug withdrawal was less frequent than in the 84 patients with DR3 (55% vs. 87%, P = 0.03). HLA DR13 occurred more often than in those with DR3 (54% vs. 15%, P = 0.0002) or DR4 (54% vs. 12%, P = 0.00005), and it was more frequent than in normal adults (54% vs. 22%, P = 0.003), including those without DR3 or DR4 (54% vs. 27%, P = 0.03). HLA DR7 was not associated with susceptibility or outcome. CONCLUSIONS: White North American patients who lack DR3 and DR4 respond differently to corticosteroid treatment than patients with classical HLA phenotypes. HLA DR13 is common in these adult patients, and it may affect treatment outcome.
