To the Editor: The effects of in-. uenza A pandemic (H1N1) 2009 vi-rus infection in HIV-infected patients are unknown. We describe an HIV-infected patient with severe pandemic (H1N1) 2009 virus infection.The patient was a 37-year-old, HIV-positive, former intravenous drug user in a methadone-substitution pro-gram. She had a history of smoking, hepatitis C, and mild chronic obstruc-tive pulmonary disease not requir-ing treatment. Since 2007 her viral load had been <50 HIV RNA copies/mL, for which she received tenofovir, emtricitabine, and lopinavir/ritonavir. Her CD4 count in March 2009 was 542 cells/μL (25%).
