Filter by: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.
The purpose of this study is to compare the efficacy of 5-day versus 10-day oseltamivir prophylactic treatment in patients who had been exposed to influenza.
This is one project of a larger ongoing study related to the immune system's response to the flu virus. This study is designed to determine how immune memory develops at the actual site of exposure, and how immunization may alter this process.
Prospective clinical study on the performance of an Influenza A+B rapid test kit. The main goal is to establish the sensitivity and specificity (i.e. how accurate the test is) when compared to a gold standard. Option of participating in this clinical study will be presented to patients displaying influenza-like illness. Informed consent will be collected from patients or patient's next of kin/guardian before samples (nasopharyngeal swab) are taken from the patient. Nasopharyngeal swabs are tested using both the investigational test kit and a predicate fluorescence immunoassay test kit. All samples will be tested using a molecular-based PCR test kit as a confirmatory test. The results will be analysed statistically and the performance of the Influenza A+B test kit can be evaluated.
A randomized, double-blinded, controlled, Phase I clinical trial to assess the safety, tolerability and immunogenicity of 'NBP607(trivalent inactivated cell-culture influenza vaccine)' compared to egg-based influenza vaccine in healthy adult volunteers
This is one project of a larger ongoing study related to the immune system's response to the flu virus. This study is designed to investigate the immune response to vaccination in pregnancy.
Upper respiratory infection , including influenza, may exacerbate the symptoms of myasthenia gravis (MG), which is an autoimmune disease that causes muscle weakness and, in some cases, can precipitate a myasthenic crisis In the present study, we investigated the incidence and risk factors of influenza infection on in myasthenia gravis patients.
This is one project of a larger ongoing study related to the immune system's response to the flu virus. This study is designed to investigate the immune response to a nasal flu immunization in tonsillar tissue compared to what can be measured in the blood.
A Phase 2, single center, randomized, double blind study evaluating the safety, efficacy, and immunogenicity of MVA NP+M1 in the H3N2 human influenza challenge model; on healthy adult volunteers.
A Phase 2b Study to Determine the Efficacy of Candidate Influenza Vaccine MVA-NP+M1 in Adults aged 18 years and over. To assess the effect of MVA-NP+M1 on the reduction of laboratory confirmed influenza when given as an adjunct to licensed quadrivalent influenza vaccine (QIV) in adults
