Objective

To assess the effect of reproductive factors, especially hormone replacement therapy (HRT) and its interaction with HLA-DRB1 *01 and/or *04 alleles on the diagnosis of rheumatoid arthritis (RA) and the presence of anti-cyclic citrullinated peptide (CCP) antibodies in women included in the ESPOIR cohort (early arthritis cohort).

Methods

568 patients were included in the analyses, which were performed using logistic regression.

Results

HRT reduced the risk of RA due to the HLA-DRB1 *01 and/or *04 alleles from OR 1.88 (95% CI 1.32 to 2.68, p<0.000) for HLA-DRB1 *01 and/or *04 alleles alone to OR 1.07 (95% CI 0.51 to 2.26, p=0.85) in women with HLA-DRB1 *01 and/or *04 alleles who received HRT. One explanation might be the protective effect of HRT on the presence of anti-CCP antibodies (OR 0.43, 95% CI 0.24 to 0.77, p<0.006). Other reproductive factors such as the number of pregnancies, menopause and age at menopause, age at menarche and a history of pregnancy with poor outcome were not associated with the diagnosis of RA and the presence of anti-CCP antibodies.

Conclusion

HRT may reduce the risk of RA due to HLA-DRB1 *01 and/or *04 alleles by protecting against the production of anti-CCP antibodies."xsd:string
