Purpose Hemolysis is a frequent adverse effect of ribavirin (RBV). Oxidative stress has been suggested to play a role, but mechanisms and predictive risk factors are unknown. Methods: Markers of redox status were determined in erythrocytes from hepatitis C infected patients with and without G6PD-deficiency before and during RBV treatment, and erythrocytes were incubated with RBV and dipyridamole, diethylmaleate or glutathione ester. Results: 5 out of 30 patients developed major RBV-induced hemolysis, which was associated with a more pronounced increase in thiobarbituric acid reactive substances (+22.5 vs. +9.4 nmol/gHb, p |
