The swine-origin influenza A (H1N1) virus is mainly responsible for flu. No hepatitis attributable to H1N1 virus has been previously documented. Herein, we report on a kidney transplant patient who developed influenza H1N1 virus-induced hepatocellular injury. The patient's body temperature was only somewhat elevated, and pulmonary and flu symptoms were mild. H1N1 virus was detected by polymerase chain reaction assay in nasopharyngeal and bronchoalveolar swabs, as well as in the serum. The hepatocellular injury episode resolved after the patient had been placed on oseltamivir therapy. This observation suggests that acute hepatocellular injury could be linked to the influenza H1N1 virus.
