Abstract
-
The current best treatment for HCV infection is combination therapy with PEG-interferon and ribavirin. This combination therapy has markedly increased the number of sustained virologic responders but is associated with various side effects, especially hematological abnormalities. We recently experienced a 45-year-old man who developed PEG-interferon induced autoimmune hemolytic anemia (AIHA) and retinal premacular hemorrhage. The worsening hemolysis after ribavirin withdrawal and exclusion of other causes implicated PEG-interferon as the cause of the AIHA. To the best of our knowledge, this is the first case reported from Korea. Treatment with PEG-interferon requires careful follow-up, as it can induce or exacerbate autoimmune diseases.
