November 5, 2020 updated by: Miguel Antonio Padilla Pimentel, MD, Universidad Dr. José Matías Delgado

Hypoglycemic Effect of Cinnamomum Verum in Type 2 Diabetic Patients in the Municipality of Comasagua

The aim of the study is evaluate the effect of cinnamon powder (Cinnamomum verum) on the glycaemia and HbA1c (Glycohemoglobin) of type 2 diabetic Salvadoran patients, whose hypoglycemic treatment is only Metformin. To carry out this objective, subjects who agree to be part of the study will subjected to measurements of their body weight, height, body mass index, waist circumference, systolic pressure, diastolic pressure, capillary glucose (with glucose meter) every 2 weeks, and their glycohemoglobin (HbA1c) at the beginning and at the end of the study.

Study Overview

Detailed Description

The study will be conducted for 12 weeks (3 months) with 30 participants diagnosed with type 2 diabetes mellitus, whose only treatment for diabetes is metformin.

Both, intervention with Cinnamon (Cinnamomum verum) and wheat flour (placebo) will be encapsulated in titanium white capsules with 500 mg of powder, that will take place in agro-industry laboratories, and will be packed in glass bottles with a content of 56 capsules and a bag of silica gel.

The data of the probable participants will verified with their medical records in the Intermediate Communitarian Unit of Family Health of Comasagua municipality (UCSFI-Comasagua). Then those who meet the criteria will contacted to be enrolled in the study, if they agreed, an informed consent will signed or stamped if the participant cannot read and write.

The randomization will be make using a list of the participants and them using the Graphpad QuickCalcs option of "Randomly assign participants to groups", assigning the participants to a group A (intervention) or B (placebo).

Participants in both groups will continue to receive the treatment they would normally receive from their respective primary care providers during the duration of the study.

The participants, who accepted and signed the informed consent, will provided with a moth calendar with the schedule of the measures. The measured variables are body weight, height, body mass index, waist circumference, systolic pressure, diastolic pressure, capillary glucose (with glucose meter) and HbA1c. The measurements will take place every 2 weeks (week 0, 2, 4, 6, 8, 10 and 12) with the exception of HbA1c which will be measured at the beginning and at the end of the study (week 0 and 12).

The obtained data will be write in the paper medical records of each participant and then exported to a database in Microsoft Excel, after that data will processed in statistical software. In case of adverse effects, this will recorded into a formulary dedicated to it, this provided to the UCSFI-Comasagua physicians with the contact data of the researchers. In addition, to perform this study the researchers make an agreement with the UCSFI-Comasagua and with the endocrinology service of the Rosales National Hospital along with the Salvadoran Association of Diabetes (ASADI) to provide health care and support to those participants who presented adverse effects.
