Furthermore, in patients with urinary tract infection (UTI), medianurinary angiotensinogen (AGT) levels were significantly increased, but urinaryproteins NGAL, L-FABP, N-acetyl-beta-D glucosaminidase (NAG) beta 2-microglobulin(BMG), serum AGT, and creatinine levels did not differ significantly between groups[30]. This evidence concerns the gene B2M and urinary tract infection.
