This study was designed to examine a possible relationship between plasma free positively charged amino acid concentrations and the degree of microalbuminuria in patients with gastrointestinal cancer. In 42 consecutive patients (22 men and 20 women), comprised of 25 with histologically proven colorectal or gastric cancer, 9 controls and 8 weight-losing patients with benign gastrointestinal disease urinary albumin and plasma amino acid analysis was performed. Microalbuminuria was more prevalent in weight-losing cancer patients (65%) compared with their weight-stable counterparts, benign gastrointestinal patients and controls. This difference reached statistical significance at the 5% level. Additionally, a significant positive correlation (rs = 0.8, p < 0.05) was observed between ornithine and urinary albumin loss in this group of patients. This study suggests that plasma free amino acid alterations in weight-losing gastrointestinal cancer patients may have an effect on renal tubular protein reabsorption.

Altered plasma levels of branched-chain amino acids (BCAAs) and aromatic amino acids (AAAs) may predict the development of insulin resistance and other type 2 diabetes mellitus (T2DM) associated comorbidities. To elucidate the role of plasma free amino acids (PFAAs) profile as a biomarker for early detection of diabetic kidney disease, quantitative measurement of PFAAs profile was determined for 90 T2DM subjects, 30 were free of nephropathy, 30 with microalbuminuria, 30 with macroalbuminuria, and in addition to 30 healthy controls. The plasma levels of valine, leucine, isoleucine, phenylalanine, citrulline, and total BCAAs were significantly increased in diabetic normoalbuminuria group when compared to controls. However, the total BCAAs level was significantly decreased in diabetic patients with micro and macroalbuminuria. Other amino acid plasma levels as tyrosine, arginine, ornithine, glycine, and the total AAAs level were significantly decreased in all diabetic subgroups compared to controls. Significant positive correlations between total BCAAs, valine, leucine, isoleucine, serum insulin, glucose, and HOMA-IR values in the diabetic normoalbuminuria group were found. The use of altered PFAAs profile as a prognostic factor in T2DM patients at risk for microalbuminuria or macroalbuminuria might reduce or prevent the incidence of end-stage diabetic renal disease.
