Ovarian reserve in children with juvenile idiopathic arthritis using biologic disease-modifying anti-rheumatic drugs.

Biologic DMARDs are reassuring in terms of ovarian reserve in girls with JIA and demonstrate that AMH is unaffected by treatment. Prospective studies with larger sample sizes are needed to confirm our findings and to evaluate the impact on the future fertility of patients. Key Points • Although biologic disease-modifying anti-rheumatic drugs (bDMARDs) are being game-changing treatment options in juvenile idiopathic arthritis, their effect on fertility and ovarian reserve is one of the most discussed issues. • In addition to treatment used, autoimmune diseases might also have a negative effect on fertility. • In this cross-sectional study, we found that anti-Mullerian hormone level of patients who were on bDMARDs, patients who were on methotrexate, and healthy controls were similar. • Our results suggest that bDMARDs are reassuring in terms of ovarian reserve in girls with JIA and demonstrate that AMH is unaffected by treatment.
