Influenza Virus Clinical Trial
Official title:
Surveillance of Influenza Virus Shedding and Immunologic Response in Immunocompromised Children and Young Adults
Influenza virus infections are a major cause of morbidity and mortality. The limited existing knowledge about the impact of influenza in immunocompromised patients suggests that they are at increased risk of influenza virus acquisition, of developing complications and of prolonged illness and viral shedding. However, some other data about the effect of antiviral agents on the infection course, and risk of resistance in immunocompromised children are lacking. The emergence of the pandemic H1N1 swine-origin influenza A virus has generated an additional need to study the epidemiology, clinical course and outcome of influenza infections in immunocompromised children. This study proposed to conduct a prospective observational clinical study to answer these questions.
This study aims to do the following;
- To evaluate the frequency of influenza virus infections due to various subtypes in
immunocompromised children and young adults at SJCRH
- To describe and compare the clinical course and outcome of pandemic H1N1 influenza
infection with that due to other influenza virus subtypes in immunocompromised children
and young adults.
- To evaluate the duration of influenza virus shedding in immunocompromised children and
young adults.
- To evaluate the immunologic response to natural infection with various subtypes of
influenza virus including the pandemic H1N1 influenza A virus.
- To evaluate the viral resistance to antiviral agents in relation to antiviral therapy.
- To compare accuracy of rapid methods for influenza A subtyping and for determination of
antiviral resistance.
