We analyzed changes in immunologic values over time for 28 hospitalized patients with pandemic (H1N1) 2009. Levels of interleukin-6, interferon-γ, and interleukin-10 increased 1 day after illness onset and then decreased to baseline levels. Levels of virus-specific antibody were undetectable 1 day after illness onset and peaked 36 days later.
Pandemic (H1N1) 2009 virus emerged in March 2009 and spread worldwide (1,2). Most patient laboratory data result from samples or information obtained on the day of hospitalization or when the patient was experiencing the acute phase of infection. Changes in laboratory data throughout the disease course have rarely been reported. We retrospectively analyzed immunologic changes for hospitalized patients through the entire course of pandemic (H1N1) 2009. These data may provide a better understanding of disease pathogenesis.
