  • Protocol summary

    Objective: The aim of this study is to determine the effects of zinc supplementation on nitric oxide and biomarkers of oxidative stress in women with polycystic ovary syndrome (PCOS). Study design: parallel double-blind randomized controlled clinical trial. Inclusion and Exclusion Criteria: Women aged 18-40 years diagnosed with PCOS will be included in this study. Individuals with neoplastic, cardiovascular disorders, malabsorptive disorders, current or previous (within the last 6 months) use of hormonal, antidiabetic medications and anti-obesity medications will be excluded in the study. Population and sample size: 60 women with PCOS eligible and referred to Kossar Clinic affiliated to Arak University of Medical Sciences, Arak, Iran in the study will be selected. Intervention: Patients will be assigned to receive either 50 mg zinc supplement (intervention group: n=30) or placebo (control group: n=30). Fasting blood samples will be taken at baseline and after 8-wk intervention to measure nitric oxide and biomarkers of oxidative stress. Start and End Date of Intervention: 8 weeks (June 10, 2014-August 10, 2014). Outcomes: Plasma nitric oxide, total antioxidant capacity (TAC), glutathione (GSH) and malondialdehyde levels in baseline and end-of-trial will be measured.

    هدف: هدف این مطالعه تعیین اثرات مکمل یاری روی بر نیتریک اکساید و بیومارکرهای استرس اکسیداتیو در زنان مبتلا به سندروم پلی کیستیک تخمدان است. طراحی مطالعه: تصادفي کارآزمایی بالینی دو سوکور موازی. معیار ورود و خروج مطالعه: زنان 40-18 ساله مبتلا به سندروم پلی کیستیک تخمدان در این مطالعه وارد خواهند شد. افراد مبتلا به نئوپلاستیک، اختلالات قلبی-عروقی، اختلالات سوء جذبی، استفاده اخیر یا قبلا (در ظرف 6 ماه گذشته) از هورمون، داروهای ضد دیابتیک و داروهای ضد چاقی از مطالعه خارج خواهند شد. حجم نمونه و جمعیت مورد مطالعه: 60 زن مبتلا به سندروم پلی کیستیک تخمدان واجد شرایط و ارجاع شده به کلینیک کوثر وابسته به دانشگاه علوم پزشکی اراک، اراک، ایران در مطالعه انتخاب خواهند شد. مداخله مورد مطالعه: بیماران برای دریافت مکمل 50 میلی گرم روی (گروه مداخله: 30=n) یا پلاسبو (گروه کنترل: 30=n) تقسیم خواهند شد. نمونه خون ناشتا در ابتدای مطالعه و 8 هفته بعد از مداخله برای تعیین نیتریک اکساید و بیومارکرهای استرس اکسیداتیو از بیماران گرفته خواهد شد. زمان مداخله: 8 هفته (از 20 خرداد 1393 تا 20 مرداد 1393). پيامدها: نیتریک اکساید، ظرفیت آنتی اکسیدانتی توتال، گلوتاتیون و مالون دی آلدئید در ابتدا و انتهای مداخله اندازه گیری خواهد شد.

Protocol summary

Study aim
The aim of this study is to determine the effects of zinc supplementation on nitric oxide and biomarkers of oxidative stress in women with polycystic ovary syndrome (PCOS).
Design
Study design: Parallel double-blind (both patients and researchers) randomized controlled clinical trial. Random assignment will be done by the use of computer-generated random numbers.
Settings and conduct
Population and sample size: 48 women with PCOS eligible and referred to Kosar outpatient Clinic affiliated to Arak University of Medical Sciences, Arak, Iran in the study will be selected.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Patients with polycystic ovary syndrome and aged 18 to 40 years will be included in this study. Exclusion criteria: Hyperprolactinemia, thyroid disorders, liver or kidney diseases, pregnancy and lactation, the use of medications such as insulin sensitizers, insulin, and diuretics, subjects following a special diet or consuming drugs with an effect on hormonal profile like oral conceptives (OCP), steroid hormones, or any other drugs probably to affect ovarian action in the last 3 months, T2DM
Intervention groups
Intervention: Patients will be assigned to receive either 50 mg zinc supplement (intervention group: n=24) or placebo (control group: n=24). Fasting blood samples will be taken at baseline and after 8-wk intervention to measure nitric oxide and biomarkers of oxidative stress. Start and End Date of Intervention: 8 weeks
Main outcome variables
Outcomes: Free testosterone, dehydroepiandrosterone (DHEA), alopecia and hirsutism (primary outcome), and other hormonal profiles, biomarkers of inflammation and oxidative stress (secondry outcomes) will be quantified at the study baseline and end-of-trial.
