Brief Summary:
Incretin-based therapies have shown significant effects beyond those on glucose metabolism. We aim in the present study to evaluate the effects of liraglutide on several cardio-metabolic risk markers.

Condition or disease
Type-2 Diabetes

Detailed Description:
In details, we will evaluate the effects of liraglutide on carotid-intima media thickness, oxidative stress, ghrelin, heat shock proteins and lipoproteins.

Drug Information available for: Liraglutide

administration of liraglutide at 1.2 mg/daily

Primary Outcome Measures :
  1. carotid intima-media thickness [ Time Frame: every four months for a total period of 2 years ]
    carotid intima-media thickness will be assessed by doppler ultrasonography

Secondary Outcome Measures :
  1. changes in oxidative stress markers [ Time Frame: after 2 months of therapy ]
    Serum LOOH levels were evaluated following the oxidation of Fe2+ to Fe3+ in the presence of xylenol orange at 560 nm. Levels of GSH were measured in serum using a spectrophotometric assay based on the reaction of thiol groups with 2,2-dithio-bis-nitrobenzoic acid, while the production of ROS was assessed using fluorescent probe dihydroethidium staining (Sigma).

  2. changes in plasma ghrelin concentrations and heat-shock proteins [ Time Frame: after 2 months of therapy ]
    plasma ghrelin concentrations and heat shock protein 60 were measured by ELISA

  3. changes in atherogenic lipoproteins [ Time Frame: after 2 and after 4 months of therapy ]
    the full LDL subclass profile (from larger and less atherogenic LDL-1 and LDL-2, to smaller denser LDL-3 to LDL-7) was assessed by gel electrophoresis (Lipoprint, Quantimetrix, USA)

Biospecimen Retention:   Samples With DNA
