Summary
Dr Kerry-Ann O'Grady aims to establish a comprehensive research program addressing acute and chronic respiratory infections in Australian children in urban, rural and remote areas. Drawing on national and international collaborations, Dr O'Grady will undertake a range of epidemiological and clinical studies that will address burden, risk, pathways to chronic lung disease and novel interventions aimed at improving lung health.
The Significance Of Human Metapneumovirus In The Australian Paediatric Population

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
Extending The MIS BAIR Randomised Trial Of BCG To Prevent Childhood Allergy And Infection

Funding Amount
$939,504.00
Summary
BCG (used till recently to prevent tuberculosis) is a potential low cost and readily available vaccine which could reduce the rates of allergy and infection in Australian children. We propose to extend our existing NHMRC-funded trial, which studies whether BCG vaccinatinon given at birth prevents the development food allergy, eczema and infection in the 1st year of life, to see if this effect continues until 5yrs of age. At this age, we can also see if BCG vaccination at birth prevents asthma.
Genetic And Environmental Factors And Early Lung Problems Can Be Related To Allergy And Poor Lung Development In Preschool Age Children

Funding Amount
$122,032.00
Summary
This important new collaboration between the Murdoch ChildrenÍs Research Institute and Barwon Health explores the impact of early lung development on longer term respiratory health. It utilises a newly validated, accurate and safe technique to measure lung function in young babies and children. Data on environmental factors and lung function will help us explore the risk factors for the development of allergy, asthma and lung infections in early life.
Investigation Into Host Susceptibility And Immune Responses In Young Children With Acute Wheezing Due To Human Rhinovirus Group C Infection

Funding Amount
$682,711.00
Summary
We recently made the surprising discovery that a new viral group, human rhinovirus group C (HRV-C), causes the majority of acute asthma in children. We also found that it causes half of the acute wheezing attacks in younger children, and is the only respiratory virus associated with allergy. So, HRV-C may be the key to the relationship between allergy and asthma. The planned project will focus on whether young children who wheeze with HRV-C have related defects in their immune system.
High Flow Cannula Therapy In Bronchiolitis, A Randomised Controlled Trial

Funding Amount
$1,283,342.00
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.
A Prospective Randomised Trial Comparing Nasogastric With Intravenous Hydration In Children With Bronchiolitis

Funding Amount
$886,817.00
Summary
This project aims to compare the two methods currently being used of providing fluid to young children who have a viral infection of the lungs called bronchiolitis. The methods of giving fluids are through a tube placed though the nose, down the food pipe, into the stomach (nasogastric tube), or through a drip in the child's vein (intravenous). We hope to show that one of these methods is better than the other and allows children to be sent home from hospital earlier, and cost less.
A Randomised Controlled Trial To Evaluate Early Intervention In Chronic Cough In Indigenous Children
Funder
National Health and Medical Research Council
Funding Amount
$1,432,252.00
Summary
This study aims to determine whether a validated evidence-based cough algorithm initiated at the development of chronic cough, defined as >4 weeks duration, following an acute respiratory illness (ARI) improves clinical outcomes in urban, rural and remote Indigenous children compared to standard care. The study will also examine the predictors of chronic cough and cough outcomes in these children as well as the cost-effectivess of the intervention.
Nasal Highflow For Paediatric Acute Hypoxic Respiratory Failure

Funding Amount
$2,627,819.00
Summary
The burden of respiratory disease in children requiring intensive care admission is increasing despite better quality care in hospitals. This study investigates a new method, called nasal high flow, to support the breathing of children, that can be provided in regular children's wards in regional and metropolitan hospitals. The study anticipates to demonstrate that early intervention with nasal high flow reduces the need for intensive care admission.
