The Effects of Micronutrients in Combination With Usual Care in Type 2 Diabetes (PMC)
2016年4月27日 更新者：Alicia L. Warnock、Walter Reed National Military Medical Center
This study is evaluating the impact of antioxidant supplements on blood sugar control and cardiovascular risk factors in adults over the age of 50 with at 3 months of Type 2 diabetes.
The investigators hypothesize that daily supplementation with a multiple micronutrient formulation containing dietary and endogenous antioxidants in combination with usual care will reduce markers of oxidative stress and inflammation in Type 2 diabetes.

详细说明
This study is evaluating the impact of an antioxidant and micronutrient supplement on markers of oxidative stress and inflammation as well as on blood sugar control in adults over the age of 50 who have had Type 2 diabetes for at least 3 months.
The purpose of this study is to see if these antioxidants reduce the oxidative and inflammatory state seen in patients with Type 2 diabetes as well as whether or not they make it easier to control blood sugar, affect the number and dosage of diabetic medications, and/or reduce the risk factors involved in long-term diabetes related complications such as in lipid profile and carotid intima-media thickness (CIMT).

- 50 years of age or older
- Stable medical status (e.g., no myocardial infarction, stroke, major surgery, or major mental illness during the previous six months)
- Not taking or not expected to be taking any oral glucocorticoids (except for replacement therapy for those with adrenal insufficiency), amphetamines, anabolic, or weight-reducing agents during the course of the study

Exclusion Criteria:
- Patients with Type 1 diabetes or those with Type 2 diabetes of less than 3 months duration.
- Inability to communicate in written and spoken English

Women who have had a hysterectomy or have not had a menstrual period for at least one year prior to consent will be considered post-menopausal and will not require a serum pregnancy test).
