  • Protocol summary

    Objective: The aim of this study is to determine the effects of selenium supplementation on insulin resistance, inflammatory factor and biomarkers of oxidative stress in gestational diabetes. Study design: Double-blind randomized controlled clinical trial. Inclusion and Exclusion Criteria: Pregnant women aged 18-40 years diagnosed with GDM at 24-28 weeks' gestation will be included in this study. The use of substitute treatments including hormone or vitamin supplements as well as those with preeclampsia, complete bed rest (CBR), intra uterine fetal death (IUFD), placenta abruption and preterm delivery will be excluded in the study. Population and sample size: 60 patients with GDM among pregnant women of 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 selenium supplement (intervention group) or placebo (control group). Fasting blood samples will be taken at baseline and after 6-wk intervention to measure metabolic profiles, inflammatory factor and biomarkers of oxidative stress. Start and End Date of Intervention: 2 months (March 17, 2014-May 17, 2013). Outcomes: Baseline and End-of-trial fasting plasma glucose (FPG), serum insulin, hs-CRP levels, plasma total antioxidant capacity (TAC) and total glutathione (GSH).

    هدف: هدف این مطالعه تعیین اثرات مکمل یاری سلنیوم بر روی مقاومت به انسولین، فاکتور التهابی و بیومارکرهای استرس اکسیداتیو در دیابت بارداری است. طراحی مطالعه: تصادفي کارآزمایی بالینی دو سوکور. معیار ورود و خروج مطالعه: زنان باردار 40-18 ساله مبتلا به دیابت بارداری (GDM) در هفته 28-24 بارداری، در این مطالعه وارد خواهند شد. استفاده از درمان های جایگزین از قبیل هورمون یا مکمل ویتامینی و همچنین آنهایی که مبتلا به پری اکلامسی، استراحت مطلق، مرگ جنینی داخل رحمی، جدا شدن جفت و زایمان زودرس می شوند از مطالعه خارج خواهند شد. حجم نمونه و جمعیت مورد مطالعه: 60 زن باردار مبتلا به دیابت بارداری 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 سلنیوم (گروه مداخله) یا پلاسبو (گروه کنترل) تقسیم خواهند شد. نمونه خون ناشتا در ابتدای مطالعه و 6 هفته بعد از مداخله برای تعیین پروفایل های متابولیک، فاکتور التهابی و بیومارکرهای استرس اکسیداتیو از بیماران گرفته خواهد شد. زمان مداخله: 2 ماه (از 26 اسفند 1392 تا 26 اردیبهشت 1393). پيامدها: گلوکز پلاسمایی ناشتا، سطوح سرمی انسولین، hs-CRP، ظرفیت آنتی اکسیدانی توتال و گلوتاتیون توتال پلاسما در ابتدا و انتهای مداخله اندازه گیری خواهد شد.
