Mechanism of Pharmacological or Toxicity Effect of Ribavirin on Kidney-Yang Deficiency Syndrome Mice Model Infected with Influenza Virus A Based on Serum Metabolomics

??OBJECTIVE To analyze the endogenous metabolite changes in the sera of kidney-yang deficiency syndrome mice infected with influenza virus A after intervention by ribavirin. And to explore the mechanism of pharmacological or toxicity effect of ribavirin. METHODS KM mice were randomly divided into three groups as normal group, model group and ribavirin group. Mice were infected with virus A after fifteen days Kidney-Yang deficiency syndrome was established. Ribavirin group were orally administrated with ribavirin for 6 consecutive days after inoculation, and the other two groups were given with equal volume of saline solution in the same way. Body weight, rectal temperature were recorded daily. Serum samples were collected from mouse 24 h after the last administration for HPLC-TOF/MS analysis. RESULTS The results show that ribavirin has good therapeutic effects on the lung index and high mortality rate of mice model. Compared with normal and model groups, the body weight and rectal temperature of them performed falling continuously. The LC-MS data were analyzed with multivariate statistical analysis and 14 potential metabolic markers were obtained which contained D-glucose, sphinganine, linoleic acid and so on. In ribavirin group, metabolism of linoleic acid, arachidonic acid and sphinganine appeared the trend of normal. And sugar and glycerophospholipid became disorders. CONCLUSION The metabolomics study and pharmacological experiment show that ribavirin might play a role of efficacy in a way that has close correlation with the linoleic acid, arachidonic acid and sphingolipid metabolic pathways. And the toxicity effect may be related to sugar and glycerophospholipid metabolic pathways.
