Protocol summary
Objective: The aim of this study is to determine the effects of vitamin D supplementation on biomarkers of inflammation and oxidative stress in patients of polycystic ovary syndrome (PCOS) with insulin resistance. Study design: Parallel double-blind (both patients and researchers) clinical trial. Randomization will be done by the use of computer-generated random numbers. Inclusion criteria: Patients with PCOS according to Rotterdam criteria aged 18 to 40 years. Exclusion criteria: Unwillingness to cooperate. Population and sample size: Among patients with PCOS referred to Kosar Clinic affiliated to Arak University of Medical Sciences, 105 patients will be selected according to inclusion and eclusion criteria. Intervention: Patients will be assigned into three groups to receive vitamin D with dosage of 4000 IU (n=35) or vitamin D with dosage of 1000 IU (n=35) or placebo (n=35). Vitamin D supplements and placebos capsules are similar in shape and size. Fasting blood samples will be taken at baseline and 12 weeks after the intervention. At the beginning and end of the intervention: 3 months. Outcomes: Biomarkers of inflammation and oxidative stress will be quantified at study baseline and end-of-trial.

هدف: هدف این مطالعه تعیین اثرات مکمل یاری ویتامین D بر بیومارکرهای التهابی و استرس اکسیداتیو در بیماران مبتلا به سندروم تخمدان پلی کیستیک با مقاومت به انسولین است. طراحي انجام مطالعه: کارآزمایی بالینی دو سوکور (هم بیماران و هم محققان) موازی. تصادفی سازی با استفاده ازجدول اعداد تصادفی ایجاد شده توسط کامپیوتر انجام خواهد شد. معیار ورود به مطالعه: بیماران مبتلا به سندروم تخمدان پلی کیستیک بر اساس معیار روتردام در محدوده سنی 18 تا 40 سال. معیار خروج از مطالعه: عدم تمایل به همکاری. حجم نمونه و جمعیت مورد مطالعه: از بین بیماران مبتلا به سندروم تخمدان پلی کیستیک ارجاع شده به کلینیک کوثر وابسته به دانشگاه علوم پزشکی اراک، 105 بیمار بر اساس معیار های ورود و خروج از مطالعه انتخاب خواهند شد. مداخله مورد مطالعه: بیماران به سه گروه برای دریافت مکمل ویتامین D با دوز 4000 واحد (35=n) یا ویتامین D با دوز 1000 واحد (35=n) یا پلاسبو (35=n) اختصاص داده خواهند شد. کپسول های مکمل ویتامین D و پلاسبو از نظر شکل و اندازه مشابه هستند. نمونه خون ناشتا در ابتدای مطالعه و 12 هفته بعد از مداخله از بیماران گرفته خواهد شد. زمان مداخله: 3 ماه. پيامدها: بیومارکرهای التهابی و استرس اکسیداتیو در ابتدا و انتهای مداخله اندازه گیری خواهد شد.

Protocol summary
Study aim
The aim of this study is to determine the effects of vitamin D supplementation on biomarkers of inflammation and oxidative stress in patients of polycystic ovary syndrome (PCOS) with insulin resistance.
Design
Study design: Parallel double-blind (both patients and researchers) clinical trial. Randomization will be done by the use of computer-generated random numbers.
Settings and conduct
Population and sample size: Among patients with PCOS referred to Kosar Clinic affiliated to Arak University of Medical Sciences, 90 patients will be selected according to inclusion and eclusion criteria.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Patients with PCOS according to Rotterdam criteria aged 18 to 40 years. Exclusion criteria: Pregnant during the intervention, androgen secreting tumors, hyperprolactinemia, thyroid dysfunction, diabetes or impaired glucose tolerance.
Intervention groups
Intervention: Patients will be assigned into three groups to receive vitamin D with dosage of 4000 IU (n=30) or vitamin D with dosage of 1000 IU (n=30) or placebo (n=30). Vitamin D supplements and placebos capsules are similar in shape and size.
Main outcome variables
Outcomes: Hormonal profiles (primary outcomes) and biomarkers of inflammation and oxidative stress (secondary outcome) will be quantified at study baseline and end-of-trial.
