The Effects of Micronutrients in Combination With Usual Care in Type 2 Diabetes

Not Applicable

Completed

• Conditions: Type 2 Diabetes
• Interventions: Dietary Supplement: Anti-oxidant and micronutrient; Drug: Placebo

• Registration Number: NCT01738802
• Lead Sponsor: Walter Reed National Military Medical Center

Brief Summary

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.

Detailed Description

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).

Exclusion Criteria

1. Patients with Type 1 diabetes or those with Type 2 diabetes of less than 3 months duration.
2. Inability to communicate in written and spoken English
3. Organ (kidney, pancreas, liver) transplant recipients
4. Individuals who are not likely to return for the follow-up because they or their sponsors are likely to have a permanent change of station or termination of service before completion of the protocol
5. Pregnancy (Women who are pre-menopausal will be informed that pregnancy must be ruled out by a serum HCG test if they would like to be considered for participation in the study. 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).
6. Patients who are routinely taking more than 81 mg aspirin (ASA)/day or who are using ASA or ASA-containing products to manage a chronic condition.

Anti-oxidant and micronutrient	Anti-oxidant and micronutrient	This group will take the anti-oxidant and micronutrient supplement.
Placebo	Placebo	This group will take the placebo.

Primary Outcome Measures

Name	Time	Method
Change in the markers of oxidative stress and inflammation	baseline, 6, and 12 months	Determining a difference between the control and experimental groups in the following markers of 1) oxidative stress: 9-Malondialdehyde (MDA) in plasma, 3-Nitrotyrosine in plasma, and Urinary levels of F2-isoprostane and 8 hydroxy,deoxyguanosine; and 2) inflammation: GM-CSF, IFN-γ, IL-1β, IL-2, L-4, IL-5, IL-6, IL-10, IL-12 (p40/p70), TNF-α.

Secondary Outcome Measures

Name	Time	Method

Change in lipid profile	baseline, 3, 6, 9, and 12 months	Compare the control and experimental groups to determine differences in lipid profile over time.
Change in CIMT	Baseline, 6 and 12 months	Determine if a difference exists in CIMT measurements between the control and experimental groups.
