  Interstitial lung disease (ILD) is frequently associated with collagen diseases, and is designated collagen vascular disease-associated ILD (CVD-ILD) that influences the prognosis of the disease. Acute-onset diffuse ILD (AoDILD) occurs in patients with collagen disease with or without underlying CVD-ILD. The prognosis of AoDILD is quite poor. It has been reported that plasma amino acid profiles are altered in rheumatoid arthritis (RA) patients. Here, we investigated the plasma amino acid profiles to determine whether they may be useful for diagnosing CVDILD or AoDILD in collagen disease. Plasma amino acid levels were analyzed using liquid chromatography/electrospray ionization tandem mass spectrometry in 64 RA patients with or without CVD-ILD, and 15 collagen disease patients with AoDILD. By using support vector machine (svm) analysis, the svm index (AA) was generated from ami.. View More»
