Title: HLA associations and Löfgren's syndrome. Author: Grunewald J. Journal: Expert Rev Clin Immunol; 2012 Jan; 8(1):55-62. PubMed ID: 22149340. Abstract: Patients with sarcoidosis can be subgrouped according to organ engagement and clinical manifestations. One such subgroup is Löfgren's syndrome (LS), constituting a distinct group of sarcoidosis patients with typical clinical manifestations, separate genetic associations and an immune response that seems to differ from that of non-LS patients. In particular, LS patients have strong associations with HLA-DRB1 alleles, and the well-known association with HLA-DRB1*03 is particularly striking. This particular HLA-DRB1 allele is also a very strong marker within that particular group of patients for a prognostically favorable disease course. This article will mainly discuss genetic associations with LS, and the possible implications of such associations.[Abstract] [Full Text] [Related] [New Search]
