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.
- 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.

The main purpose of this study is to assess the efficacy of early oseltamivir treatment (started within 24 hours of the onset of influenza symptoms) in preventing the development of acute ...
Due in part to widespread availability of oseltamivir and clinical experience using oseltamivir to treat H5N1 influenza virus infections, many strains of influenza have become resistant to...
Influenza season 2007/2008 was marked by a worldwide emergence of oseltamivir-resistant A(H1N1) viruses possessing a mutation in the neuraminidase gene causing His-to-Tyr substitution at amino acid po...
Based on our earlier discovery of N1-selective inhibitors, the 150-cavity of influenza virus neuraminidases (NAs) could be further exploited to yield more potent oseltamivir derivatives. Among the syn...

Influenza viruses are respiratory pathogens that are responsible for both seasonal influenza epidemics and occasional influenza pandemics. The narrow therapeutic window of oseltamivir, coupled with th...
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
An acetamido cyclohexene that is a structural homolog of SIALIC ACID and inhibits NEURAMINIDASE.
A genus of the family ORTHOMYXOVIRIDAE comprising viruses similar to types A and B but less common, more stable, more homogeneous, and lacking the neuraminidase protein. They have not been associated with epidemics but may cause mild influenza. Influenza C virus is the type species.
