McCann A, et al. - It has been suggested that risk markers for incident type 2 diabetes could be found in altered levels of plasma amino acids, however, established risk factors for diabetes are also connected to amino acids, so researchers assessed potential confounding for and the impact of competing risks. For this investigation, they followed prospectively 2,519 people who had coronary artery disease, but not diabetes. Potential for confounding was identified by Mixed Gaussian modelling. Two hundred sixty-seven incident cases of diabetes were recognized during a median follow-up of 10.3 years. According to results, adjustment for relevant clinical factors reduced the risk of amino acids- incident diabetes. While these findings do not preclude the potential pathogenic role of other amino acids, they suggest that arginine plasma is associated with incident diabetes independently. In an optimal model to predict new-onset type 2 diabetes, both arginine and asparagine were identified.
