A new classification of HLA-DRB1 alleles based on acid-base properties of the
amino acids located at positions 13, 70 and 71: impact on ACPA status or
structural progression, and meta-analysis on 1235 patients with rheumatoid from

OBJECTIVE: To group HLA-DRB1 alleles based on acid-base properties of amino acids
at positions 13, 70 and 71 and analyse their association with the presence of
anticitrullinated peptide antibodies (ACPA) and structural progression in 2
cohorts of early rheumatoid arthritis (RA). METHODS: Patients with RA (N=612)
from ESPOIR cohort and from EAC cohort (n=624) were genotyped for HLA-DRB1
alleles. The alleles containing the RAA sequence at positions 72-74 were
classified into 3 groups according to the amino acid at positions 13, 70 and 71:
BB encoding basic amino acids at positions 13, 70 and 71; A encoding acidic amino
acids at positions 70 and 71; and BN encoding either neutral amino acids at
position 13 and basic amino acids at positions 70 and 71, or basic amino acid at
position 13 and neutral amino acids at positions 70 and 71. The associations
between the different alleles and (1) the ACPA presence, and (2) the structural
progression were assessed by ?(2) test; a meta-analysis was performed on the 2
cohorts using the Mantel-Haenszel method. RESULTS: After meta-analysis, BB
alleles were significantly associated with ACPA presence (OR (95% CI) 4.08 (3.14
to 5.31)) and structural progression (OR (95% CI) 2.33 (1.76 to 3.09)). The
alleles protected significantly against ACPA presence (OR (95% CI) 0.37 (0.28 to
0.50)) and structural progression (OR (95% CI) 0.34 (0.23 to 0.50)). This
acid-base classification allowed to separate another group BN with an
intermediate risk of ACPA production (OR (95% CI) 1.14 (0.91 to 1.44)) and
structural progression (OR (95% CI) 1.01 (0.77 to 1.33)). CONCLUSIONS: This new
classification permitted to make a hierarchy of HLA-DRB1 alleles in terms of
association with ACPA presence or structural progression in early RA.
