Brief Summary:
Prediabetes is a common condition in overweight individuals affecting approximately 35% of American adults and 30% of Australian adults. Like diabetes, prediabetes is a serious risk factor for cardiovascular disease, eye, kidney and liver disease, and some types of cancer.
Appropriate blood glucose control is crucial in preventing pre-diabetes complications and onset of diabetes, yet clinical practice, backed by randomised trials, reports that many patients treated with standard dietary guidelines or with the first-line treatment of diabetes patients, metformin, do not improve blood glucose control sufficiently.
The overarching goal of the present project is to improve the efficacy of metformin mono-therapy in pre-diabetes and early type 2 diabetes.
Detailed Description:
Prediabetes is common in overweight and obese individuals and, as with frank diabetes, it is a risk factor for cardiovascular disease, cognitive dysfunction, fatty liver, kidney, ophthalmic, renal and neuropathic disease, and cancer.
Effective management of dysglycemia in pre-diabetes and diabetes and prevention of diabetes in individuals at risk reduce the risk of organ damage and associated co-morbidities and improves the affected individuals' quality of life.
Metformin, an oral biguanide, is the first-line treatment of newly-diagnosed type 2 diabetes patients, and the pharmacological choice for preventing diabetes in individuals with pre-diabetes. Metformin is an ideal medication to initiate for diabetes prevention, due to its excellent safety profile (lack of hypoglycemia), neutral to marginally beneficial effect on body weight, evidence of cardio-protection, and low cost. However, clinical practice, backed by randomised clinical trials, suggests that metformin mono-therapy fails to achieve glycemic goals in 20-40% of type 2 diabetes patients and to prevent diabetes in approximately 20% of individuals with pre-diabetes.
While the mode of action of metformin is still being investigated, the liver and the gastrointestinal tract are thought to be the main targets responsible for the improvement in glycemia. An increasing body of evidence suggests that the gut microbiota play an important role in obesity, prediabetes and diabetes, and alterations in gut microbial composition have been described in individuals with type 2 diabetes and pre-diabetes. Interestingly, metformin-treated diabetes patients have a "healthier" gut microbial composition compared with treatment-naïve diabetes patients, and changes in gut microbial composition with metformin treatment has been suggested to contribute to the therapeutic effect of the medication.
Randomised, clinical study with parallel assignment and single-masking will be performed in treatment-naïve individuals with pre-diabetes or early type 2 diabetes (diagnosed in the last 6 months) aiming to compare the effect of metformin (extended release \[XR\]) 1500 mg/d administered with personalized diet (based on the Weizmann Institute Personalized Nutrition Project) or administered with a healthy (low fat) diet.
