Active clinical trials for "Influenza, Human"

This is a randomized, double-blind, placebo-controlled study that will investigate the safety and clinical activity of a single intravenous (IV) dose of MHAA4549A in adult participants hospitalized with severe influenza A in combination with oseltamivir versus a comparator arm of placebo with oseltamivir.

Each year, influenza A infection caused great mortality and morbidity, especially among the elderly and individuals with chronic illness. Many of these patients are 'late presenters' who are admitted to hospital a few days after symptoms onset and have developed complications secondary to immunodysregulation. Antiviral treatment with the neuraminidase inhibitor is of limited usage for patients who presented to the hospital 48 hours after symptom onset. Apart from ventilatory and extracorporeal membrane oxygenation support, treatment options for these patients are limited. Recent animal study has demonstrated that combinations of an antiviral agent with a COX-II inhibitor can reduce mortality in mice infected with influenza virus. The investigators therefore propose to enrol patients with severe influenza A infection requiring hospitalization and oxygen support on a randomized controlled trial with celecoxib.

The trial will examine the efficacy of sambucol in the treatment of influenza. The primary efficacy endpoint will be the length of time to resolution of influenza illness.The double blind trial will be conducted at the Personnel Clinic, and at the Clinical virology Unit, Hadassah University Hospital, and will include 100 patients with laboratory-confirmed influenza infection, 50 in the sambucol and 50 in the placebo study arm.

The objective of this study is to demonstrate that influenza vaccination of nursing home workers is an effective intervention for reducing mortality of elderly people.

Influenza, also known as the flu, is a contagious respiratory illness caused by influenza viruses. The illness can range in severity, from mild to severe to even death, and it causes an estimated 500,000 to 1,000,000 deaths worldwide each year. In the last several years, there have been increasing numbers of human cases of avian influenza, or bird flu. This trend may pose a threat of a future pandemic--worldwide outbreak of disease--with an avian influenza virus that can easily spread from person to person. Oseltamivir is an antiviral medication that is used to treat people with uncomplicated human influenza, and it may be effective in treating people with either severe human influenza or avian influenza. The purpose of this international study is to compare standard-dose oseltamivir versus high-dose oseltamivir for treating people who are hospitalized with severe human influenza or avian influenza.

- Trial to assess asthma exacerbation through to the end of the study; and to demonstrate that the efficacy over one season against culture-confirmed influenza-illness; and finally to assess the safety and tolerability of CAIV-T in children with asthma.

This study seeks to determine the incidence and transmission of avian influenza viruses in humans exposed to poultry. Enrolled subjects will be selected from five different rural areas (villages) in the Nile delta region in Egypt where poultry are commonly raised. From those study sites, 2400 healthy subjects will be monitored for 6 years with annual follow up visits to measure sero-prevalence and exposure variables, and more importantly, biweekly or weekly visits to measure incidence of infection, measure secondary transmission rates, monitor symptoms, and assess immunological response. Primary Objectives: To estimate the incidence of avian influenza (AI) in poultry-exposed human populations. To estimate sero-prevalent of AI in poultry-exposed human populations. To investigate potential risk factors associated with AI human infections in poultry-exposed individuals. To investigate secondary infection risk for household contacts. Secondary Objectives: To characterize the antigenic and genetic makeup of AI viruses infecting humans. To monitor the pathogenicity and disease severity of AI viruses causing human infections and the associated immune response. To investigate the serologic response following confirmed influenza virus infection.

This is a multi-center, randomized, single-blinded, prospective, parallel group intervention study to investigate whether methotrexate (MTX) discontinuation for 1 week is non-inferior to MTX discontinuation for 2 weeks in regard to satisfactory vaccination response to a seasonal influenza.

The investigators will conduct a brief educational intervention to pregnant women who have not yet received the influenza vaccine in this pregnancy to improve the uptake of seasonal influenza vaccine.

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.
