Protocol summary
Objective: The aim of this study is to determine the effects of vitamin D supplementation on metabolic profiles in patients of polycystic ovary syndrome (PCOS). 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, 70 patients will be selected according to inclusion and eclusion criteria. Intervention: Patients will be assigned into two groups to receive vitamin D with dosage of 50000 IU (n=35) or placebo (n=35) every two weeks. 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: Metabolic profiles will be quantifid at study baseline and end-of-trial.

هدف: هدف این مطالعه تعیین اثرات مکمل یاری ویتامین D بر پروفایل های متابولیک در بیماران مبتلا به سندروم تخمدان پلی کیستیک 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، 70 بیمار بر اساس معیار های ورود و خروج از مطالعه انتخاب خواهند شد. مداخله مورد مطالعه: بیماران به دو گروه برای دریافت مکمل ویتامین D با دوز 50000 واحد (35=n) یا پلاسبو (35=n) هر دو هفته 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: پروفایل های متابولیک در ابتدا و انتهای مداخله اندازه گیری خواهد شد.
