  • Protocol summary

    Objective: The aim of this study is to determine the effects of vitamin D supplementation on treatment and metabolic profiles including insulin resistance and lipid profiles in patients with endometrial hyperplasia. 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. Inclusion criteria: Patients with endometrial hyperplasia and aged 30 to 50 years will be included in this study. Exclusion criteria: Unwillingness to cooperate will be excluded in the study. Population and sample size: 60 patients with endometrial hyperplasia of eligible and referred to Naghavi Clinic affiliated to Kashan University of Medical Sciences, Kashan, Iran in the study will be selected. Intervention: Patients will be assigned to receive either vitamin D (n=30) or placebo (n=30). Vitamin D and placebos capsules are similar in shape and size. Fasting blood samples will be taken at baseline and 16 weeks after the intervention. At the beginning and end of the intervention: 16 weeks. Outcomes: Response to treatment (primary outcomes), and insulin metabolism parameters and lipid profiles (secondry outcomes) will be quantified at the study baseline and end-of-trial.

    هدف: هدف این مطالعه تعیین اثرات مکمل یاری ویتامین D بر درمان و پروفایل های متابولیک از قبیل مقاومت به انسولین و پروفایل های لیپیدی در بیماران مبتلا به هیپرپلازی آندومتر است. طراحي انجام مطالعه: تصادفي کارآزمایی بالینی دو سوکور (هم بیماران و هم محققان) موازی. تصادفی سازی با استفاده از اعداد تصادفی ایجاد شده توسط کامپیوتر انجام خواهد شد. معیار ورود به مطالعه: بیماران مبتلا به هیپرپلازی آندومتر در محدوده سنی 30 تا 50 سال وارد مطالعه خواهند شد. معیار خروج از مطالعه: عدم تمایل به همکاری از مطالعه خارج خواهند شد. حجم نمونه و جمعیت مورد مطالعه: 60 بیمار مبتلا به هیپرپلازی آندومتر واجد شرایط و ارجاع شده به کلینیک نقوی وابسته به دانشگاه علوم پزشکی کاشان، کاشان، ایران در مطالعه انتخاب خواهند شد. مداخله مورد مطالعه: بیماران برای دریافت یا مکمل ویتامین D (30=n) یا پلاسبو (30=n) تقسیم خواهند شد. کپسول های مکمل ویتامین D و پلاسبو از نظر شکل و اندازه مشابه هستند. نمونه خون ناشتا در ابتدای مطالعه و 16 هفته بعد از مداخله از بیماران گرفته خواهد شد. زمان مداخله: 16 هفته. پيامدها: پاسخ به درمان (پیامدهای اولیه) و پارامترهای متابولیسم انسولین و پروفایل های لیپیدی (پیامدهای ثانویه) 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 treatment and metabolic profiles including insulin resistance and lipid profiles in patients with endometrial hyperplasia.
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: 60 patients with endometrial hyperplasia of eligible and referred to Naghavi Clinic affiliated to Kashan University of Medical Sciences, Kashan, Iran in the study will be selected.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Patients with endometrial hyperplasia and aged 35–55 years old will be included in this study. Exclusion criteria: Menopausal women, history of cardiovascular disease, diabetes mellitus, fasting plasma glucose (FPG) > 126 mg/dL, consumption of antihyperglycemic agents including metformin, triglycerides levels > 500 mg/dL, systolic blood pressure ≥ 160 mmHg, diastolic blood pressure ≥ 110 mmHg and untreated thyroid disease
Intervention groups
Intervention: Patients will be assigned to receive either vitamin D (n=30) or placebo (n=30). Vitamin D and placebos capsules are similar in shape and size.
Main outcome variables
Outcomes: Response to treatment (primary outcomes), and insulin metabolism parameters, lipid and metabolic profiles (secondry outcomes) will be quantified at the study baseline and end-of-trial.
