Summary

Seasonal influenza epidemics are important causes of morbidity and mortality. Cytokine dysregulation, with high levels of pro-inflammatory cytokines, occurs in patients with severe influenza. Early therapy with a neuraminidase inhibitor (NAI) is associated with better outcome in patients hospitalized with influenza, but significant mortality occurs despite use of antivirals. N-acetylcysteine (NAC) is a modified form of the amino acid cysteine, with anti-oxidant properties. NAC was shown to inhibit the production of pro-inflammatory molecules in lung epithelial cells infected with influenza viruses. Previous case report showed that high dose NAC, administered as continuous intravenous infusion, was effective and safe in improving the clinical outcomes. We aim to perform a randomized controlled trial to evaluate the therapeutic role of adjunctive NAC in the clinical management of patients with influenza complicated by lower respiratory tract involvement and abnormal respiratory status. Such information when available may reveal the potential of NAC for optimization of management of severe influenza, and provide important insights into future adjunctive therapy research.

Conditions

Interventions

DRUG

N-acetyl cysteine

N-acetyl cysteine will be administered at 100 mg/kg daily as a continuous IV infusion (in 1000ml of 5% dextrose) over 24 hrs and oseltamivir 75 mg bid orally for 5 days. Extension of dosing to 10 days for oseltamivir and the study drug is allowed if there is slow recovery, lack of improvement, or deterioration.

DRUG

5% Dextrose

5% dextrose 1 liter given over 24 hrs and oral oseltamivir 75 mg bid for 5 days. Extension of dosing to 10 days for oseltamivir and the study drug is allowed if there is slow recovery, lack of improvement, or deterioration.
