Thus, vitamin D deficiency has been associated with risk factors for the occurrence of cardiovascular disease as well as with overall mortality.In addition, there are indications that a large proportion of the population (up to 50%) is vitamin D deficient. The measurement of vitamin 25 (OH) D3 levels is the best way to estimate the vitamin D actual reserves. It is worth mentioning that elevated levels of parathyroid hormone (PTH) \\[5\\] and reduced levels of 1,25 (OH)2 vitamin D3 (calcitriol have also been associated with cardiovascular disease.\n\nThe metabolic syndrome is a sum of risk factors for cardiovascular disease and is found in approximately 25% of the Greek population.There are a lot of data linking low vitamin D levels with the metabolic syndrome as a whole as well as with its individual characteristics. Specifically, vitamin D deficiency has been associated with increased incidence of hypertension, dyslipidemia, obesity, inflammation and dysglycemia.\n\nMany studies have explored the effect of giving vitamin D supplements on the risk factors associated with the metabolic syndrome and the cardiovascular disease. The results of these studies are conflicting and this may partially be due to different doses of vitamin D used. The form of vitamin D most commonly used in these studies is cholecalciferol (vitamin D3.\n\nAim of the study:\n\nDetermination of the effect of cholecalciferol (VitD3) (2200 IU/day) on metabolic parameters in patients with metabolic syndrome.\n\nEndpoints:\n\nThe primary endpoint will be changes in metabolic syndrome parameters 3 months after starting treatment:\n\n* Waist circumference\n* Blood pressure\n* Levels of fasting serum triglycerides\n* Levels of high-density lipoprotein cholesterol (HDL-C)\n* Levels of fasting serum glucose.\n\nThe secondary endpoints will include changes in:\n\n* The levels of low-density lipoprotein cholesterol (LDL-C) and non-HDL-C\n* Subfractions of LDL-C \\[average particle size of LDL-C, levels of small dense (sd) LDL-C\\]\n* Subfractions of HDL-C (levels of small and large particle HDL-C)\n* The activity and levels of Lp-PLA2 (lipoprotein-associated phospholipase A2)\n* The levels of serum apolipoprotein AI, A-II, AV, B, E, C-II, C-III and lipoprotein (Lp) (a)\n* The activity of paraoxonase-1 (PON1)\n* The concentration of pre-beta1-HDL\n* The levels of hs-CRP (high sensitivity C-reactive protein)\n* Oxidative stress as measured by levels of 8-isoprostane in the blood and urine and oxidized LDL (oxLDL)\n* Adipokine levels (leptin, adiponectin, visfatin)\n* Glucose homeostasis (index HOMA: fasting insulin X fasting glucose/405)\n* The levels of glycosylated hemoglobin (HbA1c)\n* The levels of 25 (OH) vitamin D3, of 1,25 (OH)2 vitamin D3 and PTH\n* The levels of serum electrolytes (Ca, PO4) and the activity of alkaline phosphatase (ALP) in serum.\n\nStudy population:\n\nThe investigators will study patients with metabolic syndrome (n = 50 adults) attending the Outpatient Lipid and Obesity clinic at the University Hospital of Ioannina. Diagnosis of the Metabolic Syndrome will be based on the criteria of National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III).\n\nAll patients will be instructed to exercise and lose weight according to the NCEP-ATP III diet. The participants will be randomized in an open manner into one of the following 2 treatment groups: a) cholecalciferol (VitD3) (2200 IU/day) plus lifestyle measures or b) only lifestyle measures.
