Genetic association of autoimmune hepatitis and human leucocyte antigen in German patients

2006

To report on our large German collective and updated data of 142 patients with autoimmune hepatitis (AIH) type 1.Key investigations performed were liver biopsy, serum autoantibodies as well as serum markers such as IgG and elevated transaminases. Antinuclear antigen (ANA) and smooth muscle antigen (SMA) autoantibodies characterized type 1 AIH. Type 3 (AIH) was solely characterized by the occurrence of soluble liver antigen/liver-pancreas antigen (SLA/LP) autoantibodies either with or without ANA or SMA autoantibodies.Most prevalent HLAs were A2 (68 patients, 48%), B8 (63 patients, 44%), C7 (90 patients, 63%), DR3 (49 patients, 38%), DR4 (49 patients, 38%) and DQ2 (42 patients, 30%).

Antigens of the major histocompatibility complex in patients with chronic discoid lupus erythematosus.

1990

summary The frequencies of the major histocompatability complex class I, class II and class III antigens were determined in 130 patients (88 women and 42 men) with chronic discoid lupus erythematosus, and compared with those of 764 healthy controls. A significant increase in HLA-B7 (38.0% in the patients vs. 25·8% in the control group), HLA-B8 (29·5% vs. 17·4%), HLA-Cw7 (58·9% vs. 26·1%), HLA-DR2 (46·9% vs. 29·7%), HLA-DR3 (32·0% vs. 19·4%), HLA-DQwi (76·6% vs. 60·5%), and a decrease in HLA-A2 (41·9% vs. 55·7%) was found. The calculated relative risk values for the respective antigens markedly increased when two or more antigens were present in one patient, with a maximum relative risk valu…

HLA-DR phenotypes and blood levels of T cell subsets

1984

Blood mononuclear cell and T cell subsets values were analyzed in 53 Sicilian individuals according to HLA-DR phenotypes. The results demonstrate that DR1-positive subjects show a significant increase of blood T cell subsets whereas DR3-positive subjects show a non-significant decrease of these values. These results suggest that gene(s) associated with HLA-DR could be one of the factors which affect blood levels of T cell subsets.
