급성 골수성 백혈병 환자에서 발생한 Oseltamivir 내성 대유행 인플루엔자(H1N1 2009) 1예 = A Case of Oseltamivir-Resistant Pandemic Influenza (H1N1 2009) in a Patient with Acute Myeloid Leukemia

다국어 초록 (Multilingual 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 oseltamivirresistant 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.
