Opisthorchis viverrini infection induces inflammation-mediated oxidative stress and liver injury, which may
alter α-tocopherol and lipid metabolism. We investigated plasma α-tocopherol and lipid profiles in hamsters
infected with O. viverrini. Levels of α-tocopherol, cholesterol, and low-density lipoprotein increased in the
acute phase of infection. In the chronic phase, α-tocopherol decreased, while triglyceride and very lowdensity
lipoprotein increased. Notably, high-density lipoprotein decreased both in the acute and chronic
phases. In the liver, cholesteryl oleate, triolein, and oleic acid decreased in the acute phase, and increased
in the chronic phase. Such chronological changes were negatively correlated with the plasma α-tocopherol
level. The expression of α-tocopherol-related molecules, ATP-binding cassette transporter A1 (ABCA1) and
α-tocopherol transfer protein, increased throughout the experiment. These results suggest that O. viverrini
infection profoundly affects on lipid and α-tocopherol metabolism in due course of infection.
