Protocol summary
-
Study aim
-
The aim of this study is to determine the effects of alpha-lipoic acid (ALA) supplementation on serum some biochemical variables in women with gestational diabetes mellitus (GDM).
-
Design
-
In this double blind study, a total number of 60 women with GDM will be selected. They will be divided into two groups of intervention (ALA) and control (placebo) by simple randomization method. They will be matched in age and BMI.
-
Settings and conduct
-
The aim and procedures of the study will be conveyed to the participants and written informed consent will be obtained from each of them. Patients were not aware of the type of drug and the statistician was not aware of the type of groups.
-
Participants/Inclusion and exclusion criteria
-
Major inclusion criteria are no history of GDM and not consumption of vitamin and mineral supplements during the last 6 months. Major Exclusion criteria are preterm delivery, preeclampsia, the need for insulin or oral medication for lowering blood sugar during the intervention and bed rest.
-
Intervention groups
-
Supplement group will receive ALA (one 100 mg capsule for 8 weeks) and the control group will receive placebo capsule containing cellulose acetate with the same dosage and period.
-
Main outcome variables
-
Serum levels of glucose, hemoglobin A1c, insulin, lipid profile, antioxidant capacity and malodialdehyde.
