Serum tryptophan (TRP), kynurenine (KYN), and picolinic acid (PA) in patients with chronic viral hepatitis.
| TRP (μmol/L) | KYN (μmol/L) | PA (μmol/L) | |
|---|---|---|---|
| Healthy controls (n = 40) | 79.8 (61.2–102.8) | 3.6 (2.2–5.25) | 0.2 (0.2–1.81) |
| Chronic hepatitis C infection (n = 51) | 65.8 (53.8–77.4) | 3.0 (0.5–5.0) | 1.7*(0.2–6.7) |
| Chronic hepatitis B infection (n = 12) | 61.5 (48.4–74.2) | 2.6 (0.44–4.1) | 1.02*(0.2–5.0) |
