    Abstract:
    BACKGROUND: The atherogenic index of plasma (AIP), defined as logarithm [log] of the ratio of plasma concentration of triglycerides to high-density lipoprotein (HDL) cholesterol, has recently been proposed as a predictive marker for plasma atherogenicity and is positively correlated with cardiovascular disease risk. The nutrient combination of chromium picolinate and biotin (CPB) has been previously shown to reduce insulin resistance and hyperglycemia in patients with type 2 diabetes (T2DM). METHODS: Thirty-six moderately obese subjects with T2DM and with impaired glycemic control were randomized to receive CPB or placebo in addition to their oral hyperglycemic agents for 4 weeks. Measurements of blood lipids (including ratio of triglycerides to HDL cholesterol), fructosamine, glucose, and insulin were taken at baseline and after 4 weeks. RESULTS: At the final visit, the active group had a significantly lower AIP compared to the placebo group (P < 0.05). A significant difference in triglyceride level (P < 0.02) and the ratio of low-density lipoprotein (LDL) to HDL cholesterol (P < 0.05) was also observed between the groups at the final visit. In the active group, the changes in urinary chromium levels were inversely correlated with the change in AIP (P < 0.05). Urinary chromium levels were significantly increased in the CPB group. In the CPB group, glucose levels decreased at 1 hour and 2 hours and glucose area under the curve and fructosamine level were significantly decreased. Ratios of total to HDL cholesterol, LDL to HDL cholesterol, and non-HDL to HDL cholesterol were significantly decreased between the treatments at final visit. No significant adverse events were observed in the CPB or placebo groups. CONCLUSIONS: These results suggest that the combination of chromium picolinate and biotin may be a valuable nutritional adjuvant therapy to reduce AIP and correlated CVD risk factors in people with T2DM.
