Plasma amino acids [28] of 40 female patients with rheumatoid arthritis (RA), 24 male patients with ankylosing spondylitis (ASp) and 19 controls (14 females and 5 males) were investigated. In RA-patients 19 amino acids showed statistically significant differences from healthy people of which 18 were decreased. In ASp-patients 14 amino acid concentrations were statistically altered whereby 10 showed enhanced values. In female RA-patients and controls a linear dependency between distinct amino acids (threonine, glutamic acid, proline, alanine, citrulline, tyrosine, phenylalanine, ornithine, lysine and 3-methylhistidine) and advanced age could be demonstrated.
