Clinical Trial Summary

The study aims at the identification and the quantification of urinary branched-chain amino acids (BCAAs) by mass spectometry in healthy subjects and patients with insulin resistance and correlating urinary BCAAs with HOMA index. Blood and urine levels of BCAAs will be correlated with HOMA index to assess and quantify insulin resistance. Identification and quantification of urine BCAAs by an innovative method based on synthetic biology will also be performed. Correlations between mass spectometry and the innovative detection method of BCAAs will be searched.


Clinical Trial Description

Blood and urine samples will be collected in 330 persons to assess BCAAs levels and correlate them with HOMA index. Persons included will be: 110 persons with BMI>27 and HOMA >4 with no diabetes 110 persons with BMI>27 and HOMA < 4 with no diabetes 110 persons with BMI < 27 and HOMA <4 with no diabetes, including at least 50 men and 50 women, 30 aged 18-35, 30 aged 36-55, 30 aged 56-75. Urine BCAAs will be measured by both mass spectrometry and the innovative method based on synthetic biology. ;
