Study Details

Study Description

Brief Summary

Chronic non-infectious diseases have a bigger impact and a higher prevalence every day world-wide. Among them, diabetes stands out being the number one cause of death from degenerative chronic illness in Mexico. Diabetes not only affects quality of life, it can also lead to severe complications that have a great economic impact as well as a health impact on the patient and their family. Some of the complications include liver failure and hypertension. This whole problem can be dated back to an initial hyperglycemic state that when left untreated further develops into insulin resistance, chronic inflammation, metabolic syndrome and diabetes. The purpose of this study is to stop this chain reaction that starts with every hyperglycemic patient by adding thiamine pyrophosphate to the treatment plan of patients diagnosed with type 2 diabetes that are poorly managed with metformin monotherapy. Thiamine pyrophosphate is a form of B1 vitamin that plays an important role as a coenzyme in multiple metabolic routes including the link between glycolysis and Krebs cycle, fatty acids metabolism and branched-chain amino acid metabolism. By doing so, these pathways improve their function and efficiency and thereby utilize plasma glucose. This in turn, decreases the formation of advanced glycation end products (AGEs) which prevents the formation of reactive oxygen and nitrogen species, ultimately there is also an anti-oxidative mechanism involved that improves the inflammatory state the patient is living with. Our hypothesis is that by adding thiamine pyrophosphate to the treatment of patients taking metformin, there will be important progress regarding the inflammatory and metabolic control of patients with type 2 diabetes.

The study will have a duration of approximately 4 months after the total sample is recruited. During this time, subjects will first be examined to determine their eligibility according to the pre-established criteria, in case of inclusion in the study they will sign an informed consent after reading it thoroughly and having answered all their questions. Baseline labs will be taken for every subject for future comparison. They will then be randomized into two parallel groups: an experimental group that will receive weekly infusions of saline infused with 1 gram of thiamine pyrophosphate or a placebo group that will also receive weekly infusions of pure saline. The patients as well as the doctors treating them will be blinded to the assignment of either group. This model will be carried out for a duration of 12 weeks total, during which every patient will continue their metformin treatment with their tolerated dose. There will be verification of treatment adherence by counting the metformin pills during every weekly visit. For the assessment of dependent variables there will be a visit every month with a blinded doctor. These visits will be for: physical and clinical evaluation, evaluation of adverse events, evaluation of treatment adherence and a heart rate variability study. The first and third months a questionnaire about lifestyle will be added to the visit schedule. On the third month, final lab tests will be performed. Finally, one month after completing the treatment, a final visit will be scheduled for a clinical and physical evaluation to make sure there are no problems.

Metformin at patient´s tolerated oral dose (maximum of 2550 mg per day) and thiamine pyrophosphate (weekly dose of 1 gram administered by IV: 25 ml of thiamine pyrophosphate + 250 ml saline solution at a 60-80 drops/minute rate). Total duration of 12 weeks.

Dietary Supplement: Thiamine pyrophosphate
12 weeks of weekly dose of 1 gram of thiamine pyrophosphate administered in an intravenous manner with saline solution
Other Names:
  • Cocarboxylase
  • Drug: Metformin
    All participants will continue taking metformin in their previous established tolerated dose for the duration of the study

    Placebo Comparator: Placebo group

    Metformin at patient´s tolerated oral dose (maximum of 2550 mg per day) and weekly administration of 275 ml of saline solution at a 60-80 drops/minute rate). Total duration of 12 weeks.

    Other: Placebo
    12 weeks of weekly dose of 275 ml of saline solution administered in an intravenous manner

    Drug: Metformin
    All participants will continue taking metformin in their previous established tolerated dose for the duration of the study

    Outcome Measures

    Primary Outcome Measures

    1. hemoglobin A1c [Change from baseline at 3 months]

      percentage

    Secondary Outcome Measures

    1. fasting plasma glucose [Change from baseline at 3 months]

      mg/dl

    2. Lipids profile [Change from baseline at 3 months]

      Concentration of total cholesterol, HDL, LDL and triglycerides (mg/dl)

    3. inflammation markers [Change from baseline at 3 months]

      Concentration of PCR, IL-6, TNF-alpha, nitric oxyde, superoxide dismutase, free fatty acids, catalase

    4. Lifestyle measurement [Change from baseline at 3 months]

      IMEVID questionnaire (instrumento para medir el estilo de vida en diabéticos). Total scores are reported from 0-100. Higher scores are associated with a better lifestyle, >75 quartile is considered a good score.

    5. heart rate variability [Change from baseline at 3 months]

      measured in milliseconds

    6. arterial elasticity [Change from baseline at 3 months]

      Using the HDI/PulseWave instrument
