Summary
Aboriginal children in the Top End of Australia have high rates of hospital admission for diarrhoea and malnutrition. We have discovered that underlying small intestinal damage in these children is an important contributor to the high complication rates and longer lengths of stay in hospital compared to non-Aboriginal children.

We have discovered that underlying small intestinal damage in these children is an important contributor to the high complication rates and longer lengths of stay in hospital compared to non-Aboriginal children. This research proposes to continue our work on small intestinal damage by using two non-invasive tests of gut function, namely a sugar absorption test and novel breath test. The sugar permeability test involves the children drinking a solution of the two sugars lactulose and rhamnose, and measuring their absorption into the blood 90 minutes later using a sophisticated measuring instrument called HPLC, which can measure minuscule amounts of sugars and is set up at Royal Darwin Hospital. The breath test involves children drinking another sugar solution with a special non-radioactive marker called a stable isotope of carbon, and measuring changes in the amount of this marker in carbon dioxide from the breath at timed periods after drinking the sugar solution. The breath is analysed in Adelaide using another sophisticated instrument. These tests are being used to measure abnormal sugar absorption due to intestinal damage, which is particularly common in Aboriginal children during the weaning period of 4-18 months. Our hypothesis is that treatment with 'healthy germs' (probiotics) like those in certain yoghourts will colonise the gut, stimulate immunity and reduce the presence of 'nasty germs' (pathogenic bacteria) in the intestines of Aboriginal children which contribute to the need for their hospitalisation with diarrhoea and malnutrition. If this hypothesis is correct, then this research will provide the best kind of evidence for reducing the need for hospital treatment by treating all cases of diarrhoea with these probiotics and possibly even decreasing the gut damage of children in the weaning period by including probiotics in their dietsRead moreRead less
Cystic Fibrosis - Insulin Deficiency, Early Action (CF-IDEA)

Summary
Cystic Fibrosis (CF) is the most common life-threatening genetic condition affecting Australian children. As well as repeated lung infections, children with CF develop insulin deficiency and eventually diabetes. The CF-IDEA trial (Cystic Fibrosis _ Insulin Deficiency, Early Action) will determine whether starting insulin treatment before the onset of diabetes (earlier than current practice) will improve the health of children with CF by improving body weight and lung function.
