Protocol summary
Objective: The aim of this study is to determine the effects of vitamin E supplementation on lipid profiles in patients with diabetic nephropathy. 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 diabetic nephropathy and aged 40 to 85 years will be included in this study. Exclusion criteria: Unwillingness to cooperate will be excluded in the study. Population and sample size: 50 patients with diabetic nephropathy 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 E (n=25) or placebo (n=25). Vitamin E 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: 12 weeks. Outcomes: Lipid profiles (primary outcomes), biomarkers of oxidative stress (secondry outcomes) will be quantified at study baseline and end-of-trial.

هدف: هدف این مطالعه تعیین اثرات مکمل یاری ویتامین E بر پروفایل های لیپیدی در بیماران مبتلا به نفروپاتی دیابتی 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 نفروپاتی دیابتی در محدوده سنی 40 تا 85 سال وارد مطالعه خواهند شد. معیار خروج از مطالعه: عدم تمایل به همکاری از مطالعه خارج خواهند شد. حجم نمونه و جمعیت مورد مطالعه: 50 بیمار مبتلا به نفروپاتی دیابتی 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 E (25=n) یا پلاسبو (25=n) تقسیم خواهند شد. کپسول های مکمل ویتامین E 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: 12 هفته. پيامدها: پروفایل های لیپیدی (پیامدهای اولیه)، بیومارکرهای استرس اکسیداتیو (پیامدهای ثانویه) در ابتدا و انتهای مداخله اندازه گیری خواهد شد.

To decrease potential confounding effects, all participants will have stratified randomization according to BMI and age. Then, participants in each block will be randomly allocated into two treatment groups to take either vitamin E supplement or placebo. Randomization will be done by the use of Stat Trek software.
