Abstract
Objective. To evaluate the ovarian reserve in women with systemic sclerosis (SSc) and to analyze the relationship of the concentration of anti-Müllerian hormone (AMH) with the main manifestations of the disease and therapy. Material and methods. The study included 74 SSc patients aged 18 to 40 years; the control group consisted of 32 healthy women, matched by age. The concentration of follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, estradiol (E2) and testosterone was determined by enzyme immunoassay (ELISA), AMH quantitatively using standard chemiluminescent analysis on paramagnetic particles in blood serum. The AMG level of 1.0– 10.6 ng/ml was taken as normative values. Values <1.0 were regarded as a decrease in ovarian reserve. Results. In patients with SSD, the levels of AMH and testosterone were significantly lower than 1.4 [0.5; 2.3] and 0.45 [0.2; 0.96], respectively, versus 2.4 [1.8; 3.3] (p=0.002) and 1.6 [0.97; 2.5] (p=0.0001) in the control. The concentration of prolactin and E2 was recorded higher with SSDs – 22.23 [14.08; 31.18] and 140.2 [102.43; 179.74], respectively, against 10.2 [7.11; 16.68] (p=0.000002) and 95.3 [64.50; 130.0] (p=0.002) in the control. A decrease in the ovarian reserve by the level of AMH was significantly more often detected in patients with SSD in 43% versus 9.4% in the control (p=0.002). The risk of AMH reduction in patients with SSD was 7 times higher compared to the control (OR=7.030; 95% CI: 1.97–25.11). The levels of the hormones studied were comparable in patients with low and normal ovarian reserve. Diffuse form (46.9%) and subacute course of the disease (53.1%) were more often detected in patients with SSD and with low ovarian reserve compared to those with normal ovarian reserve (23.8% (p=0.033); 23.4% (p=0.004)). The frequency of organ lesions of SSDs, immunological disorders, inflammatory markers, and the lipid spectrum in the groups did not differ depending on the level of AMH. There were also no differences in the regimens and doses of treatment with basic anti-inflammatory drugs and glucocorticoids. Menstrual cycle disorders were noted by 31% of patients with SSD versus 6.2% in the control (p=0.004). Premature ovarian insufficiency (POI) was detected in 6.8% of patients with SSD and none in the control group (p=0.02). Patients with SSD and POI did not differ in age, duration of illness, clinical manifestations and therapy of them without POI.Conclusion. The concentration of AMH and testosterone was significantly lower in patients with. A decrease in ovarian reserve was significantly more often detected in women with SSs. Low ovarian reserve was more often detected in patients with diffuse form and subacute course of the disease. POI was more often observed in the group of SSc.
