Cinnamomum Cassia Effect on IGF1 and Metabolic Control in Patients With DM2 Without Glycemic Control Metformin Treated (CICAFAC1)
Effect of Cinnamomum Cassia as an Enhancer of the Insulin Response of the Insulin-Like Growth Factor-1 and Metabolic Control in Patients With Type 2 Diabetes Mellitus Treated With Metformin Without Glycemic Control
Among the multiple treatment options for Diabetes Mellitus Type 2 (DM2), the influence on Insuline like growth factor 1 (IGF1) plays a causal role in diabetes but has shown similarities with insulin, both in its structure and in its function, including a rapid reduction in glucose levels in blood, could improve glycemic control in patients.
Oral administration of 3 g of cinnamomum cassia for 90 days acts as an enhancer of the IGF1 insulin response and on metabolic control (fasting glucose, glycosylated hemoglobin (HbA1c), triglycerides, total cholesterol, high density cholesterol, low density cholesterol, very low density cholesterol, systolic and diastolic blood pressure (TAS and TAD), body weight) in patients with DM2 without glycemic control treated with metformin at doses ≤ 850 mg daily.

Detailed Description
Introduction:
DM2 is a chronic disease, considered a public health problem, scenario in which each year increases the number of people affected, has a high prevalence in the investigator's country, 9.4% (ENSANUT 2016), which causes a high morbidity and mortality. Conceptually it is defined as a heterogeneous syndrome originated by the genetic-environmental interaction and characterized by a chronic hyperglycemia, as a consequence of a deficiency in the secretion or action of insulin, which triggers acute complications (ketoacidosis and hyperosmolar coma), microvascular chronicles (retinopathies) and neuropathies) and macrovascular (coronary heart disease, cerebrovascular and peripheral vascular diseases).
Growth hormones such as IGF1 with important biological effects on metabolism have been shown to promote the absorption of glucose in certain peripheral tissues. It has been shown that IGF1 binds to insulin receptors to stimulate the transport of glucose in fat and muscle, inhibiting the production of hepatic glucose by lowering blood glucose while at the same time suppressing insulin secretion, increasing sensitivity to insulin and improves the lipid profile.
For the treatment of DM2 the use of botanical products can improve glucose metabolism by hypoglycemic effect, as well as that of lipids and antioxidant, aqueous extracts of cinnamomum cassia have been shown to enhance glucose uptake and glycogen synthesis in vitro and increase phosphorylation of the insulin receptor with possible effect on IGF1 receptor.
The emergence of other therapies can generate new treatments for patients with DM2, which in turn reduce costs and help improve the quality of life.
Justification:
The prevalence of diabetes and metabolic decontrol is high both in Mexico and in the world and conditions the development of long-term complications. The concentrations of IGF1 in blood are diminished in the patients with diabetes mellitus and by its effects similar to the insulin in the metabolism of the glucose when normalizing this can produce control of the diabetes.
In vitro studies have shown that cinnamomum cassia increases glucose uptake, glycogen synthesis and insulin receptor phosphorylation. In humans it has been confirmed that it increases the levels of glucagon-like peptide 1 (GLP-1), favors the activation of peroxisome proliferator-activated receptor (PPAR-γ and PPAR-α) promoting insulin sensitivity, as well as inhibits hepatic 3-hydroxy 3-methylglutaryl coenzyme A reductase to reduce the synthesis of cholesterol and has a vasodilator effect by activity on the enzyme nitric oxide synthase.
Cinnamomum cassia also has a proposal on the signaling of IGF1 receptors (GRB2), which activated by phosphatidylinositol 3-kinase (PI3K) control the proliferation of IGF1, this IGF1 having reduced levels in patients with diabetes becomes a therapeutic target for improved control metabolic. However, the direct application of IGF1 has as main limitation important collateral effects which has inhibited its use, so it is intended to evaluate the stimulatory effect on IGF1 with cinnamomum cassia considering phytopharmaceutical of good quality and low side effects.
General hypothesis:
Cinnamomum cassia acts as an enhancer of the insulin response of IGF1 and metabolic control in patients with DM2 without glycemic control treated with metformin at low doses.
Goals:
GENERAL To evaluate the effect of cinnamomum cassia as an enhancer of the insulin response of IGF1 on metabolic control in patients with DM2 without glycemic control treated with metformin.

- Insulin sensitivity, body mass index (BMI), waist circumference, % body fat.
- Determine the pharmacological attachment and tolerability of CC and placebo.
Working universe:
Patients with DM2, (men and women with a recent diagnosis, treated with 850 mg of metformin daily, without glycemic control). Residents of Guadalajara and metropolitan area and that for the development of the protocol they will go to the facilities of the National Medical Center of the West, Specialty Hospital.
Sample size:
It was calculated according to the following formula for clinical trials: n= 2 [ (Zα - Z1-β) (δ) / d] 2 Two working groups will be formed at random, which will be integrated as follows: 1) a group of 14 patients (7 women and 7 men) with DM2 without adequate control, treated with metformin 850 mg daily, who will receive 1 g of cinnamomum cassia orally every 8 hours, for 90 days, and 2) a group of 14 patients (7 women and 7 men) with DM2 without adequate control, treated with metformin 850 mg daily, who will receive 1 g of placebo (calcined magnesia ) orally every 8 hours, for 90 days. In this way, the total number of participants required for the study will be, at least, 28 volunteers.
Variables:
Independent variable:
Pharmacological intervention:
- Intervention group: Administration of metformin 850mg daily and cinnamomum cassia 1g orally before each meal, for 90 days.
