Serum anti-Müllerian hormone levels in women with rheumatoid arthritis during tumor necrosis factor-α inhibitor treatment: Exploratory research.

BACKGROUND: We evaluated serum anti-Müllerian hormone in women with rheumatoid arthritis newly introduced to tumor necrosis factor-α inhibitor treatment for 54 weeks to investigate the treatment's effect on ovarian reserve. METHODS: A total of 12 premenopausal women with rheumatoid arthritis aged 20-50 years were recruited at our division, who had been newly treated with tumor necrosis factor-α inhibitor (infliximab or etanercept) from 1 April 2008 to 31 March 2014. Serial serum anti-Müllerian hormone levels and disease activity scores (DAS28-CRP) were examined at defined periods: start of treatment and 14, 30, and 54 weeks after start of treatment. RESULTS: DAS28-CRP scores in 12 women were significantly decreased from a mean of 4.6 (±SD: 0.4) to 2.3 (±0.4) after 54 weeks of treatment (p < 0.001). Serum anti-Müllerian hormone levels and its z scores did not change significantly. CONCLUSION: Treatment with a tumor necrosis factor-α inhibitor did not affect serum anti-Müllerian hormone levels in 12 women with rheumatoid arthritis during 54-week treatment.
