Abstract

Objective To assess ovarian reserve markers and anti-corpus luteum (anti-CoL) antibodies in dermatomyositis (DM) patients. Methods Forty female DM patients were invited to participate. Exclusion criteria included hormonal contraceptive use within the last six months, neoplasia associations, overlapped systemic autoimmune diseases, current pregnancy, gynaecological surgery and individual choice not to participate. The final experimental group for this cross-sectional study included 16 DM patients and 23 healthy controls, each of whom was evaluated during the early follicular phase of the menstrual cycle. Values for IgG anti-CoL (via immunoblotting), follicle stimulating hormone (FSH), estradiol, inhibin B, anti-Mullerian hormone (AMH) serum levels (via ELISA) and sonographic antral follicle count (AFC) were determined. Results DM patients and controls were of comparable mean age (p>0.05). The mean age of DM onset was 29.1 +/- 4.7 years, with disease duration of 5.6 +/- 3.2 years. Menstrual cycle characteristics, comorbidity and lifestyle were similar amongst patients in both groups (p>0.05). AMH values of <= lng/mL (p=0.027) and AFC values (p=0.017) were significantly reduced in DM patients relative to the control group, whereas serum estradiol levels (p<0.001) were higher in DM patients compared to controls. In contrast, serum FSH and inhibin B levels, ovarian volumes, and anti-CoL antibody frequency were similar in both groups. Differences in AFC and estradiol were determined to be significant following Bonferroni correction for multiple testing. Conclusion We identified a diminished ovarian reserve in DM patients of reproductive age. Further studies are necessary to assess the idiopathic inflammatory myopathy-related factors involved in the ovarian impairment of this patient population. (AU)
