Effect of Dapagliflozin Administration on Metabolic Syndrome, Insulin Sensitivity, and Insulin Secretion
Effect of Dapagliflozin Administration on Metabolic Syndrome, Insulin Sensitivity, and Insulin Secretion
The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult
 population suffers the disease.

 Dapagliflozin is an inhibitor of the sodium-glucose co-transporter SGLT2 in the kidney and is
 a novel treatment for diabetes type 2. Some studies indicate that SGLT2 inhibitors have
 benefits on blood pressure, triglycerides levels and help to raise the levels of high density
 lipoproteins cholesterol (c-HDL).

 The aim of this study is to evaluate the effect of dapagliflozin on metabolic syndrome,
 insulin sensitivity and insulin secretion.

 The investigators hypothesis is that the administration of dapagliflozin modifies the
 metabolic syndrome, insulin sensitivity and insulin secretion.
A randomized, double-blind, placebo-controlled clinical trial its going to carry out in 24
 patients with a diagnosis of metabolic syndrome in accordance with the International Diabetes
 Federation (IDF). Waist circumference, glucose, insulin levels, lipid profile, creatinine and
 acid uric are going to be load after a 75 g of dextrose load.

 12 patients will receive Forxiga (dapagliflozin), 10 mg, one per day before breakfast during
 3 months.

 The remaining 12 patients will receive placebo at the same dose.

 There will be calculated Area Under the Curve of glucose and insulin, total insulin secretion
 (insulinogenic index), first-phase of insulin secretion (Stumvoll index) and insulin
 sensitivity (Matsuda index).

 This protocol it's already approved by the local ethics committee and written informed
 consent it's going to be obtained from all volunteers.

 Results will be presented as mean and standard deviation. Intra and inter group differences
 are going to be tested using the Wilcoxon signed-rank and Mann-Whitney U-test respectively;
 p≤0.05 it's going to be considered significant.
