Magnesium Treatment of Inflammation in Disorders of Glucose Homeostasis

Study Overview
=================
Brief Summary
-----------------
In most diabetic patients where low blood magnesium levels occur the important depletion of cellular levels is usually not measured. This study will measure both blood and oral mucosal cell magnesium levels before and after 3 months of supplementation with magnesium tablets (the recommended dietary amount of 336 milligrams per day). These magnesium levels will be correlated with blood levels of indicators of inflammation (eg C reactive protein) to see whether the cellular levels are more reliable than blood levels of magnesium for appropriate treatment of magnesium deficiency in diabetic patients.

Detailed Description
-----------------
The anti-inflammatory effects of oral magnesium (Mg) supplementation of diabetic and metabolic syndrome patients with low serum Mg levels have been studied with increased interest in recent years. However, serum magnesium levels only represent less than one percent of total body magnesium; whereas cellular deficiency of Mg is a more reliable parameter to assess repletion of this essential mineral for correlation with indices of inflammation. The proposed research will compare the efficacy of a 3 month period of treatment with oral Mg of diabetic patients selected for elevations of CRP, TNFα and other markers of inflammation on cellular and serum levels of Mg. We anticipate that 50 hypomagnesemic diabetic patients will be selected for 3 months of supplementation with 336 mg of Mg lactate tablets. The repletion of serum and oral epithelial cell Mg levels will be correlated with responses of CRP, TNFα, substance P, HgbAIc and oxidative/nitrosative (ROS/RNS) stress parameters before and after treatment. Individuals will be selected from the Dasman Diabetes Institute in Kuwait. With completion of these analyses, a collaborative manuscript with joint authorship will be prepared and submitted for publication.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The magnesium cellular levels will provide a stronger correlation with antiinflammatory indicators compared to the circulating serum levels of magnesium. | 50 hypomagnesemic diabetic patients will receive magnesium tablets ( recommended dietary allowance)for 3 months and circulating inflammatory indicators will be measured. The blood and cellular levels of magnesium will be measured (before and after treatment) to assess which parameter correlates best with efficacy in lowering inflammation indicators. | One year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Magnesium supplementation will lower parameters of inflammation in hypomagnesemic diabetic patients. | Antiinflammatory indicators (CRP, TNF alpha, isoprostane, Hemoglobin A1c etc) will be measured prior to and after 3 months of magnesium supplementation . | One year |
