Cystic Fibrosis and Bronchiectasis Research

About

Cystic Fibrosis is a genetic disorder resulting in damage to the lungs and elsewhere. The resulting changes associated with this disease increase the risk of chronic bacterial infection, lung function decline and overall ill health, both physical and mental. 

The Cystic Fibrosis and Bronchiectasis Research Group is investigating how patients may benefit from novel drug therapies, diagnostic imaging techniques, molecular epidemiology of infection and psychosocial interventions.

The group has an excellent track record in attracting competitive research grants, both from Australian and international sources. They are recognised as world leaders and have an extensive collaborative network with the leading researchers in cystic fibrosis throughout Australia and internationally.

People

The Cystic Fibrosis and Bronchiectasis Research Group are made up of a multi-disciplinary team of doctors, nurses, physiotherapists and allied health staff. The team is committed to assisting in the search for new and improved treatments and providing high-quality care for patients with cystic fibrosis and bronchiectasis.

Current research projects

• Effects of high intensity interval training (HIIT) exercise on people with cystic fibrosis.
• The effect of the MetaNeb® System in the adults with cystic fibrosis when used in conjunction with usual airway clearance techniques (ACT) on lung clearance, lung mechanics and airflow limitation during periods of clinical stability and hospitalisation.
• Real-life study on bacterial air contamination in an adult cystic fibrosis clinic.
• Clostridium difficile infection in adult patients with cystic fibrosis in Western Australia: disease burden and clinical impact.
