[Ovarian function in patients of childbearing age with systemic lupus erythematosus].

OBJECTIVE

To explore the ovarian function and its influencing factors in women of childbearing age with systemic lupus erythematosus (SLE).

METHODS

A total of 107 female patients diagnosed with SLE at Peking University People' s Hospital from January 2017 to May 2024, aged between 20 and 40 years, were included in the study. At the same time, 40 matched healthy women aged between 20 and 40 years were selected as controls. Serum levels of anti-Müllerian hormone (AMH) were measured using the chemiluminescence method in both the control group and the SLE patients. The general clinical characteristics and medication history (including hormones, immunosuppressants, and biological agents) of the SLE patients were obtained through case retrieval. Changes in serum AMH levels before and after treatment with biological agents in the SLE patients were analyzed.

RESULTS

(1) The AMH levels in the SLE patients were significantly lower than those in the healthy control group [1.475 (0.344, 3.030) μg/L . 2.934 (1.893, 4.761) μg/L, < 0.001]. (2) The level of AMH in the SLE patients with normal menstruation was significantly higher than that in the patients with irregular menstruation [1.931 (0.638, 3.414) μg/L . 0.335 (0.159, 1.527) μg/L, =0.004]. No statistical differences were found in clinical characteristics and laboratory indicators between the groups with decreased AMH group and normal AMH group. (3) The multivariate logistic regression analysis revealed that age (=1.124, 95%: 1.033-1.224, =0.007) and disease duration (=1.100, 95%: 1.017-1.190, =0.018) were identified as significant risk factors for the decline in AMH levels. (4) After 6 months of treatment with telitacicept, the AMH level was significantly higher than that before treatment [2.050 (0.763, 4.259) μg/L . 1.988 (0.473, 2.822) μg/L, =0.043]. There was no significant difference in AMH level between patients receiving rituximab treatment for 6 months [2.026 (0.376, 2.267) μg/L . 1.545 (0.503, 3.414) μg/L, =0.127].

CONCLUSION

Ovarian function is decreased in SLE patients of childbearing age, and age and disease duration are the risk factors. The utilization of biological agents demonstrates favorable safety profiles regarding ovarian function in childbearing-age patients with SLE.
