A vitamin-sized capsule, containing gas sensors, is to be fully developed for assessing the state of health and diagnosing the diseases relevant to gastrointestinal tract. The capsule travels along the tract, transmitting information about the gas species generated by the microorganisms of the gut, which is closely associated with the health of the human under surveillance. The information will be invaluable for diagnostics and adjusting the diet to mitigate and cure the diseases of the guts.

One of the greatest challenges facing contemporary genetics is to understand the genetics of complex diseases such as inflammatory bowel disease, mutiple sclerosis and schizophrenia. This application seeks to unravel the complex interactions between susceptibility genes and environmental triggers that work together to produce the inflammatory bowel diseases (IBD).

This application seeks to unravel the complex interactions between susceptibility genes and environmental triggers that work together to produce the inflammatory bowel diseases (IBD). Current estimates of the prevalence and incidence suggests that there may be 30-40,000 Australians who suffer from these chronic debiltating set of diseases known separately as Crohn's disease and ulcerative colitis. One susceptibility gene for Crohn's disease has been recently been identified and the project outlined will extend our knowledge not only to the susceptibility genes themselves, but also to the genes that interact with them to produce the disease via a cascade of immune and inflammatory events. This work is part of a large international effort to identify all IBD susceptibility genes and builds on the resources of the Australian IBD Familiy Register- an Australia wide register of families in which multiple members are affected by CD or UC. A traditional gene mapping approach is used in concert with mutiple analyses of different gene expression profiles in disease versus normal bowel tissues as well as in cell lines from patients versus controls. Validation studies include identification of the particular tissues and cell types that are involved in the pathological immune response typical of IBD as well as characterisation of specific patient genotypes and- or phenotypes that may correlate with expression profiles. Results obtained will be used to identify genes underlying IBD susceptibility, the mutations that drive the disease and eventually therapeutic targets for modulation and treatment of disease.Read moreRead less
Neuroimmune Interactions In Functional And Organic Gastrointestinal Diseases

Summary
Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD) are chronic, incurable diseases of the lower gastrointestinal tract with unknown causes and poor treatment options. Both the immune and nervous systems are altered in GI disease, but have traditionally been studied in isolation. My research investigates how the neuro-immune axis is altered in these diseases, using animal models and human tissue samples to identify novel treatment options for these debilitating diseases.
Faecal Microbiota Transplantation And Other Novel Therapeutic Microbial Manipulation Strategies In Inflammatory Bowel Disease

Summary
There is growing interest in the role of microbial-based strategies including faecal microbiota transplantation (FMT) for the treatment of inflammatory bowel disease. This project will develop such strategies into valid treatment options through a combination of clinical & basic science work including (1) characterising viral & fungal factors of importance, (2) evaluation of novel orally-delivered formulations of FMT, and (3) development of better defined, more reproducible microbial treatments.
Vagal Nerve Stimulation As A Novel Therapy In Inflammatory Bowel Disease

Summary
Inflammatory bowel disease (IBD) is common exerting a large personal and societal burden to the Australian population. Current medications used to treat IBD are expensive, have many side effects and at times require hospitalisation for their administration. We aim to develop the non invasive and inexpensive technique of vagal nerve stimulation as a novel treatment strategy for IBD.

Summary
Intestinal inflammation, in gastroenteritis, Crohn's disease, ileitis or colitis, has effects on the motility (movement) of the gastrointestinal and on secretion within it. The symptoms that are recognised are poor digestion, crampy pains and diarrhoea. The symptoms often continue after the inflammation has subsided. The major disease entity that can develop after inflammation is the irritable bowel syndrome (IBS). IBS is associated with persistent disorders of bowel motility.

The symptoms that are recognised are poor digestion, crampy pains and diarrhoea. The symptoms often continue after the inflammation has subsided. The major disease entity that can develop after inflammation is the irritable bowel syndrome (IBS). IBS is associated with persistent disorders of bowel motility. The symptoms are triggered by changes in the properties of enteric neurons, many of which become hyperexcitable. Enteric neurons are part of the nervous system within the gut wall. However, the neurons that have changed properties after inflammation have not been identified, and the mechanisms of change are not known. This work is designed to determine the molecular basis of the changes in neuron excitability that lead to hyperexcitability. Identification of the molecules whose properties are changed will permit those molecules to be targeted in the design of compounds to treat the abnormalities of intestinal physiology that follow inflammation.Read moreRead less

Summary
Ulcerative Colitis (UC) is a chronic inflammatory condition affecting the large bowel. It is the result of a dysfunctional immune system that inappropriately targets and damages the colon. There is increasing evidence that gut bacteria play a crucial role in UC, possibly by stimulating inappropriate activation of immune cells. We believe that by "transplanting" the faeces (and thus gut microbes) of healthy individuals into the colon of UC patients, we may change the bacterial make up and correct ....Ulcerative Colitis (UC) is a chronic inflammatory condition affecting the large bowel.

Summary
Inflammatory bowel disease is a significant cause of debility in the Australian community. Some patients develop narrowing of the bowel which can cause intestinal blockages and require surgery. My research in this area will identify predictors of severe disease, allowing doctors to individualise treatment plans for each patient. I will also work to determine the best model of medical treatment and investigate new techniques which have the potential to avoid surgery.
Exclusive Enteral Nutrition In Children With Crohns Disease

Summary
Crohn's disease occurs at any age, even in young children. One treatment for CD involves the use of a special drink (nutritional treatment). This works well for CD in children, helping to settle symptoms and heal the bowel surface. Despite being established as a treatment for 20 years, it is not yet clear how it works. These studies aim to work out how nutritional treatments work in CD. This should expand our knowledge about CD and may lead to further ways to prevent or manage CD.
Stricture Definition And Treatment (STRIDENT) Studies: New Diagnostic And Treatment Modalities For Inflammatory Bowel Disease Strictures

Funding Amount
$124,676.00
Summary
Inflammatory bowel disease (IBD), which includes Crohn disease and Ulcerative colitis, is becoming increasingly common in Australia. IBD strictures, which are a narrowing of bowel wall as a result of inflammation, can cause obstruction or blockage of food and liquid contents in the bowel. This results in significant patient morbidity and disease burden. Our research will aim to characterise strictures in IBD and investigate novel medical treatments to significantly improve outcomes in IBD.
