Text: The concentrations of total cysteine (367. 0 + / -43. 9 vs 360. 4 + / -33. 5 nmol/ml, mean + / -95 % confidence interval), glutathione (12. 5 + / -1. 6 vs 14. 1 + / -1. 3 nmol/ml) and homocysteine (21. 2 + / -4. 5 vs 19. 6 + / -5. 2 nmol/ml) were similar in patients with chronic hepatitis C and healthy control subjects Supplementation with N-acetylcysteine resulted in measurable concentrations of N-acetylcysteine in plasma, but did not significantly increase the concentrations of cysteine, glutathione or homocysteine.
