PG - 96-102 AB - AIM: Human leukocyte antigen (HLA) DR status affects the clinical features of autoimmune hepatitis. In Caucasians, patients with DR3 have poorer outcomes. In Japan, the relationship between HLA DR status and clinical features has yet to be fully examined. METHODS: We investigated 79 patients with type 1 autoimmune hepatitis who underwent liver biopsy and were screened for HLA DR status by the polymerase chain reaction sequence specific oligonucleotide hybridization method. RESULTS: Fifty-five patients had DR4 and 23 had DR2. Thirteen patients had both DR2 and DR4. None had DR3. Of patients aged <30 years, 70% did not have DR4. A tendency toward higher serum levels of immunoglobulin G was seen in patients with DR4 compared to those without, while patients with neither DR2 nor DR4 had lower serum levels of immunoglobulin G than those with only DR2 and those with only DR4. Patients with DR2 had a lower frequency of concurrentautoimmune disease. Concurrence of thyroid disease was seen only in patients with DR4. The cumulative incidental rate of the normalization of serum alanine aminotransferase levels within six months after the introduction of corticosteroid treatment was not associated with HLA DR status. CONCLUSION: HLA DR status is considered to affect the clinical features of Japanese patients with type 1 autoimmune hepatitis. Japanese patients with DR2 may have different clinical features from others. In addition, diagnoses of type 1 autoimmune hepatitis should be made carefully in Japanese patients with neither DR2 nor DR4 and in those aged <30 years.
