Polymyositis (PM) affects female gender during reproductive age; however, there is no study assessing ovarian reserve in these patients to evaluate ovarian reserve markers in PM. Eight female patients with PM (Bohan and Peter criteria, 1975) with aged 18-40 years, followed at our tertiary centre from March 2011 to May 2014, were invited to participate. They were age-matched with 16 healthy individuals (control group). All were evaluated at early follicular phase of menstrual cycle. Follicle stimulating hormone (FSH), estradiol, inhibin B, anti-Müllerian hormone (AMH) serum levels (ELISA) and sonographic antral follicle count (AFC) were determined. PM patients and controls had comparable mean age (31.4 ± 6.5 vs. 30.7 ± 6.2 years, P = 0.946), ethnicity and socioeconomic class (P > 0.05). PM mean age of onset was 27.3 ± 6.5 years and disease duration of 6.5 ± 4.1 years. Menstrual cycles were alike in both groups with a similar frequency of age at menarche, gynaecological age, duration and length of menstrual cycle (P > 0.05). The median serum level of AMH was significantly lower in PM compared to controls [0.7(0.3-3.4) vs. 3.1(1.4-4.0), P = 0.021]. AMH levels ≤1 ng/mL (50 vs. 6.3 %, P = 0.024) and very low AFC (37.5 vs. 6.3 %, P = 0.037) were significantly in PM patients versus controls. The other hormones (FSH, inhibin B and estradiol levels) were similar between both groups (P > 0.05). The present study was the first to identify subclinical ovarian dysfunction in PM patients during reproductive ages. Further study is necessary to assess the possible role of PM-related factors that may influence the ovarian function of these patients.

The present study demonstrated for the first time that a high cumulative methotrexate dose is a possible cause of subclinical ovarian dysfunction in adult c-SLE patients. Further studies are required to confirm this deleterious effect in other rheumatic diseases, particularly juvenile idiopathic arthritis and idiopathic inflammatory myopathy.

Women suffering from PAPS possessed reduced ovarian reserve, with prevalence greater than 50%.

This study aims to assess ovarian reserve markers in Behçet's disease (BD) patients. Ten BD and 22 healthy controls were evaluated for ovarian reserve by examining the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, inhibin B, total morning testosterone, prolactin, thyroid-stimulating hormone (TSH), and antral follicle count. Anti-Müllerian hormone (AMH) was measured using two different enzyme-linked immunosorbent assay (ELISA) kits. Demographic data, menstrual abnormalities, disease parameters, and treatments were also analyzed. The median current age was similar in BD patients and controls (34 (20-40) vs. 31.3 (20-42) years, p = 0.33). A positive correlation was observed between the AMH Gen II ELISA and AMH/MISAnshLabs ELISA assays in the BD patients (r = +0.98; p < 0.0001) and healthy controls (r = +0.93; p < 0.0001). The mean AMH by Gen II (0.93 ± 0.8 vs. 2.59 ± 1.8 ng/mL, p = 0.01) and AMH/MIS AnshLabs ELISA (1.07 ± 0.86 vs. 2.51 ± 1.8 ng/mL, p = 0.02) were significantly reduced in the BD patients versus controls. A trend of decreased AMH (<1.0 ng/mL) was observed in BD patients compared to that in the controls (50 vs. 19 %, p = 0.09) using either kits. The mean FSH was significantly higher in the BD patients compared to that in the controls (9.1 ± 3.6 vs. 6.5 ± 2.7, p = 0.04). No differences were found for the other ovarian parameters in both groups (p > 0.05). Current disease activity was only observed in BD patients with a low AMH level; however, there was no statistical significance (40 vs. 0 %, p = 0.44). Cyclophosphamide use was reported in only one patient with a low AMH and high FSH level. The present study was the first to suggest that BD patients may have diminished ovarian reserve. The contribution of disease activity remains to be determined.
