Likewise, we found that the haplotype DRB1*03:01-DQB1*02:01, which is part of the 8.1 ancestral haplotype, a major genetic determinant of autoimmune diseases confers significant risk to develop autoantibodies (OR=19.23, 95%CI 2.37–155.9; p=0.0088 after Bonferroni's correction). Also, the HLA-DRB1*03:01 allele was associated with higher mortality in patients with HP (adjusted OR=5.9, 95%IC 1.05–33.05; p=0.043).Conclusions A subset of HP patients presents circulating autoantibodies and higher mortality, that are associated with some alleles of 8.1 ancestral haplotype.FootnotesThis manuscript has recently been accepted for publication in the European Respiratory Journal.
