    AbstractRibavirin is one of the major agents used in combination therapy with interferon for chronic hepatitis C, but is often associated with hemolytic anemia as a serious adverse event. Employing metabolome analysis, we demonstrated that the concentrations of intermediate metabolites produced by glycolysis and the pentose phosphate cycle in patients' erythrocytes were significantly decreased after administration of ribavirin. Our findings suggest that hemolysis associated with ribavirin is triggered by an energy crisis and consequent oxidative stress, thus having implications for the prevention of such hemolysis.
