Reduced Ovarian Function in Female Rheumatoid Arthritis Patients Trying to Conceive
OBJECTIVE: Subfertility, a time to pregnancy (TTP) longer than 12 months, is present in 40% of female patients with rheumatoid arthritis (RA) who are actively trying to conceive. Because patients with RA appear to reach menopause at a younger age, diminished ovarian function may explain the reduced...

Sumario: | OBJECTIVE: Subfertility, a time to pregnancy (TTP) longer than 12 months, is present in 40% of female patients with rheumatoid arthritis (RA) who are actively trying to conceive. Because patients with RA appear to reach menopause at a younger age, diminished ovarian function may explain the reduced fertility. Serum anti‐Müllerian hormone (AMH) levels are the best proxy to measure ovarian function. Our objectives were to study AMH levels in female patients with RA and determine the association of preconception serum AMH levels with TTP. METHODS: A post hoc analysis was performed before conception in patients of the Pregnancy‐Induced Amelioration of Rheumatoid Arthritis (PARA) cohort. Serum AMH levels were compared with those in an existing cohort of healthy controls using analysis of covariance. Associations between AMH and TTP were studied using the Cox proportional hazard analysis. RESULTS: Preconception serum was available in 209 women of the PARA cohort (aged 32.1 ± 3.9 years), of whom 45% were subfertile in the current episode. The median AMH level was 2.5 μg/l (interquartile range: 1.5‐4.6). AMH levels were significantly lower compared with those in healthy controls (P < 0.001), with 17% of patients having levels below the age‐specific 10th percentile. A multivariable analysis showed a negative association of AMH with the presence of anticitrullinated protein antibodies (ACPAs) (P = 0.009). AMH levels showed no significant association with TTP (P = 0.26). CONCLUSION: Women with RA have lower AMH levels than healthy controls, and AMH levels were lower in ACPA‐positive patients. However, because preconception AMH levels were not associated with TTP, the reduced AMH levels do not explain the reduced fertility in patients with RA. |
