[Assessment of ovarian reserve with anti-Müllerian hormone in female patients with systemic lupus erythematosus].
OBJECTIVE
To evaluate the serum level of anti-Müllerian hormone (AMH) in female patients with systemic lupus erythematosus (SLE) and identify its correlations with age and cyclophosphamide (CYC) therapy.


METHODS
A total of 77 SLE female patients and 38 control healthy women with regular menstrual cycles were recruited. AMH was measured by enzyme linked immunosorbent assay (ELISA) kit. Follicle-stimulating hormone (FSH), estradiol (E2) and antral follicle count (AFC) of bilateral ovary were detected at the third day of menstrual cycle.


RESULTS
Their mean age was (29 ± 5) years (range, 20-40) and the mean duration (2.7 ± 2.4) years. The mean serum level of AMH was (1.5 ± 1.3) µg/L and AFC 10 ± 7. Linear regression revealed AFC (r = 0.9, P < 0.01) was associated with the level of AMH. The mean levels of AMH and AFC were significantly higher in patients naїve to CYC therapy than in those under exposure, but lower than that in healthy control (P < 0.01). No difference existed in FSH and E2 among 3 groups. Compared with those above 30 years old, the patients aged 30 years and younger had significantly higher level of AMH (P < 0.01). The Spearman's correlation analysis indicated that each 5 gm of CYC exposure were independently associated with a lower level of AMH (r = -0.4, P < 0.01).


CONCLUSIONS
As a more sensitive marker of ovarian reserve, AMH is associated with age and the cumulative dose of CYC. SLE patients aged >30 years and under exposure to CYC >10 g should be closely monitored for potential adverse events.
