Summary
This project seeks to characterize the inflammatory mechanisms triggered during severe respiratory virus infections that result in hospitalization of infants. These are associated with later development of asthma. We aim to identify new molecular targets for anti-inflammatory drug development, with the long term goals of improving treatment for acute disease, and prevention of subsequent asthma.
High Flow Cannula Therapy In Bronchiolitis, A Randomised Controlled Trial

Summary
Bronchiolitis is the leading cause of paediatric hospitalisation in Australia. Despite multiple research studies the outcome has not changed. Our recent studies supported by other international studies have shown that the use of high flow nasal cannula oxygen may reduce the severity and prevent progression of the disease. We aim to investigate if HFNC in regional hospitals can reduce the number of infants transferred to specialist children’s hospitals and reduce the socio-economic burden.

Summary
A newly discovered paramyxovirus, human metapneumovirus (hMPV), shows clinical and virological charcteristics very similar to those of human respiratory syncytial virus (hRSV). Human RSV is the major cause of acute lower respiratory illness in infants and accounts for more than 1 million deaths world wide annually. Most infants are infected in their first year of life, and re-infection is common. Genetic variation of the virus is thought to play a critical role in its ability to escape the immun ....A newly discovered paramyxovirus, human metapneumovirus (hMPV), shows clinical and virological charcteristics very similar to those of human respiratory syncytial virus (hRSV). Human RSV is the major cause of acute lower respiratory illness in infants and accounts for more than 1 million deaths world wide annually. Most infants are infected in their first year of life, and re-infection is common. Genetic variation of the virus is thought to play a critical role in its ability to escape the immune response and establish multiple sequential infections in the same host. Currently, we have no knowledge of the extent that hMPV exists in the Australian population, nor do we know if hMPV is a significant respiratory pathogen in paediatric patients. This research aims to determine the importance of hMPV as a respiratory agent, and will establish the rate, age of exposure, and incidence of hMPV infection in Australian children. In addition, we will identify the hMPV strains (genotypes) that infect local children, and the difference, if any, between these and virus strains detected in children from other community groups, and from overseas. Such data is invaluable in devising a future vaccine strategy for hMPV, and the study of the genetic variability among Australian strains will have profound implications for public health. This research project is a preliminary study into the clinical and virological significance of hMPV, in children, and will form a basis for future research projects. Once this preliminary data is obtained, further studies are possible to determine the cellular immune response to hMPV infection and its role in long-term protection. Also,it is likely that hMPV, like hRSV, may prove to be an agent associated with long-term decreased pulmonary function and airflow limitation perhaps developing to asthma.Read moreRead less
Is There Cytomegalovirus In Mothers Breastmilk And Does It Cause Infection In Very Premature Babies?

Summary
The hypothesis behind this study is that some very premature infants become infected with cytomegalovirus (CMV) from their mother's breast milk. This proposal is for a study of 200 CMV antibody positive mothers who are expressing breast milk for their very premature infants. We believe this is likely to be about 50% of all mothers. It has been well established that some full term infants are infected with CMV from their mother's breastmilk. The question now is do very premature infants with poor ....The hypothesis behind this study is that some very premature infants become infected with cytomegalovirus (CMV) from their mother's breast milk. This proposal is for a study of 200 CMV antibody positive mothers who are expressing breast milk for their very premature infants. We believe this is likely to be about 50% of all mothers. It has been well established that some full term infants are infected with CMV from their mother's breastmilk. The question now is do very premature infants with poor immunity develop serious infections from cytomegalovirus. This project has the overall aim of determining what proportion of very premature infants become ill with CMV excreted in their mother's breast milk, and then determining the nature and severity of those illnesses. It will also define how many mothers of premature infants are excreting CMV in their breast milk, the time this starts after birth, the viral load transmitted to the infant, the age after birth when the infants first become infected, the proportion who become ill with the infection, the details of the diseases and whether freezing breast milk kills the CMV.Read moreRead less
