Brief Summary:

Several mechanisms have been implicated in the pathophysiology of the complications of diabetes mellitus (DM), one of them is the formation and accumulation of a heterogeneous group of compounds called advanced glycation end products (AGEs). The interaction of these compounds with their receptor, the receptor for advanced glycation end products (RAGE) triggers several signalling pathways which will lead to increase in inflammatory molecules and enhanced reactive oxygen species. In addition, to the membrane receptor RAGE, there are two soluble forms, the soluble RAGE (sRAGE) and the endogenous secretory RAGE (esRAGE), these soluble receptors are capable to bind AGEs and block the AGE-RAGE axis. It has been observed that in diabetes the needs of thiamine are increased, and it could be an inhibition of the pentose phosphate pathway (thiamine is an essential cofactor in this pathway) and activation of other metabolic pathways among them AGEs formation. It has been proposed that supplementation of benfotiamine could decreased the risk of micro and macrovascular complications, and this could be in part because a decreased in the formation of AGEs. For this reason, the objective of this study was to evaluate the effect of benfotiamine on AGEs and its soluble receptors (sRAGE) in patients with type 2 diabetes.

The specific objectives in the current study are:

  1. To evaluate and compare clinical and anthropometric characteristics in type 2 DM patients with and without benfotiamine treatment.
  2. To evaluate and compare in type 2 DM patients with and without benfotiamine treatment the following biochemical parameters: total AGEs, Carboxymethyl-lysine (CML), sRAGE, glucose, hemoglobin A1c, lipids (total cholesterol, C-HDL, C-LDL, and triglycerides).
  3. To evaluate and compare dietary data such as dietary AGEs and macro and macronutrients in type 2 DM patients with and without benfotiamine treatment.

Type of study: This is a randomized, controlled, double-blind clinical trial

Methods 34 patients will be recruited, 17 per group. After signing the inform consent subjects will be assessed for inclusion criteria. Subjects meeting the inclusion criteria and those whom accept to participate will be randomized to receive either a placebo or benfotiamine treatment for 12 weeks.

At the end of the 12 weeks all the basal assessments will be repeated.

Placebo Comparator: Placebo
450 g per pill, 2 pills per day to get 900 mg per day
Dietary Supplement: Placebo
Placebo 900 mg per day

Active Comparator: Benfotiamine
Benfotiamine (S-Benzoylthiamine O-monophosphate) 450 mg per pill, 2 pills per day to get 900 mg per day
