[Assessment of efficiency of dietotherapy with addition of a vitamin-mineral complex in patients with diabetes mellitus type 2].

The influence of diet inclusion of vitamin and mineral complex (VMC), potassium and magnesium in the form of asparaginate on micronutrient status, body composition and biochemical parameters in patients with diabetes mellitus type 2 (DM2) has been investigated. 120 female patients with DM2 and obesity of I-III degree (mean age - 58 +/- 6 years) have been included in the study. The patients were divided into two groups: main group (n = 60) and control group (n = 60). For 3 weeks patients of both groups received a low-calorie diet (1600 kcal/day). Patients of the main group received VMC, providing an additional intake of vitamins C and E (100-120% RDA), beta-carotene (40% RDA), nicotinamide (38% RDA), pantothenic acid and biotin (60% RDA), vitamins B12, B2 and folic acid (75-83% RDA), vitamins B1 and B6 (160-300% RDA), zinc (100% RDA) and chromium (400% RDA), and also received magnesium (17.7% RDA) and potassium (9.4% RDA) in the form of asparaginate. Body composition, biochemical parameters and micronutrient status (blood serum level of vitamins C, D, B6, B12, folate, potassium, calcium, magnesium, zinc, phosphorus) were evaluated in all patients before and after the 3-week course of diet therapy. After the low-calorie diet therapy average body weight reduction was 4.2 +/- 0.2 kg in the main group, and 4.4 +/- 0.1 kg in the control group, without statistically significant differences between groups. Statistically significant decrease of total cholesterol, triglycerides, and glucose concentration in blood serum was registered in both groups. It should be noted that in the control group glycemia decreased on 1.2 +/- 0.1 mmol/l, while the main group showed a decrease on 1.8 +/- 0.1 (p < 0.05) to normal values (5.4 +/- 0.1 mmol/l). Initial assessment of vitamin and mineral status revealed that most patients were optimal supplied with vitamins and minerals. After the dietotherapy significant increase of vitamin C, 25-hydroxyvitamin D, vitamin B6, folate, vitamin B12, potassium, magnesium, calcium, zinc and phosphorus concentration in blood serum was observed in patients receiving VMC. While in the control group statistically significant decrease of vitamin C, magnesium, zinc and phosphorus concentration in blood serum after the treatment was revealed. The obtained data shows the necessity of addition of the vitamin-mineral complex to the diet of patients with DM2 and obesity.
