Summary

Adult patients hospitalized with influenza have higher viral loads and more severe illnesses. Thus more aggressive treatment approaches (e.g. higher dose oseltamivir) have been suggested to treat patients suffering from severe influenza infection. The investigators plan to investigate the impact of higher-dose oseltamivir (150 mg b.d.) treatment on viral clearance and clinical recovery in adult patients hospitalized for severe influenza. Such information may lead to optimization of the management strategy used for these patients.

Detailed description

* The investigators plan to study the impact of higher-dose oseltamivir (150 mg b.d.) treatment on rate of viral load decline and RNA negativity (in nasal and throat swabs, assessed by quantitative RT-PCR assay) and time to clinical recovery in adult patients hospitalized for severe influenza. * Patients who received intervention (oseltamivir 150 mg b.d. for 5 days) will be compared to those in the non-intervention arm (patients may receive oseltamivir treatment at 75 mg b.d. for 5 days, decided by their managing physicians) in the two respective study sites. Viral load changes and viral clearance will be compared. Clinical progress and time to symptom recovery will be reported. The protocol will be crossed-over to the other site at a defined time frame. * oseltamivir 150 mg b.d. has been shown to be safe and well-tolerated in earlier clinical trials * higher-dose treatment has been suggested by health authorities (e.g. WHO) to treat severe influenza infection/pneumonia.
