- Reduced ovarian reserve in patients with adult polymyositis(2015) SOUZA, Fernando Henrique Carlos de; SILVA, Clovis Artur da; YAMAKAMI, Lucas Yugo Shiguehara; VIANA, Vilma dos Santos Trindade; BONFA, Eloisa; SHINJO, Samuel KatsuyukiPolymyositis (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-Mullerian 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 a parts per thousand currency sign1 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.

H. C. de; SHINJO, S. K.; YAMAKAMI, L. Y. S.; VIANA, V. S. T.; BARACAT, E. C.; BONFA, E.; SILVA, C. A.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.conferenceObject Subclinical Reduced Ovarian Reserve in Adult Polymiositis Patients(2015) SOUZA, Fernando Henrique Carlos de; SILVA, Clovis A.; YAMAKAMI, Lucas Yugo Shiguehara; VIANA, Vilma S.
