- Abstract: Oseltamivir is the drug of choice for patients with pandemic influenza (H1N1 2009). However, sporadic cases of oseltamivir resistance have been described worldwide. Up to March 2010, a total of 11 strains (2.2% of tested isolates) of oseltamivir-resistant pandemic influenza (H1N1 2009) have been discovered in South Korea. We report a case of 46-year-old man with acute myeloid leukemia in whom an oseltamivir-resistant pandemic (H1N1) 2009 virus was isolated. Despite high dose oseltamivir therapy for 10 days he had persistent symptoms and showed positive results in repeated real-time RT-PCR for pandemic influenza (H1N1 2009) virus from nasopharyngeal specimen. The patient improved eventually after oseltamivir was replaced by zanamivir inhalation.
