Chronic inflammatory demyelinating polyneuropathy has a strong association with HIV and HCV infection. A rare association between chronic inflammatory demyelinating polyneuropathy and hepatitis C treatment with pegylated interferon alpha was described recently. We described the first case of chronic inflammatory demyelinating polyneuropathy associated with pegylated interferon alpha 2b in a white man infected with HIV and HCV. The patient recovered completely with the use of intravenous hyperimmune immunoglobulin. Infectologists and hepatologists should be alert regarding this rare and serious association, which requires immediately drug discontinuation and early treatment.
