Hookworms and coeliac disease!

Tuesday, April 20th, 2010

 

coeliac disease researchIn 2008 a trial which involved reintroducing hookworms into patients with coeliac disease was commenced in Brisbane, Queensland. The first phase was completed in 2009. While 2010 has seen the trial roll over into a second extended phase. The results have been presented at several national and international meetings and publication of the results is pending. 

The trial is based around the theory of the “hygiene hypothesis” which in brief, suggests that as we’ve become cleaner (or more hygienic) we have effectively removed parasites from our bowel. These are organisms with which humans have co-evolved with over tens of thousands of years, and to which our immune system may have developed a symbiotic dependent relationship – i.e. each helping the other to ensure their normal function and survival. By effectively removing these parasites we may have allowed our immune system to be overactive in certain areas which may have predisposed us to certain “autoimmune conditions” such as coeliac disease. This theory is supported by the observation that as we have improved our “cleanliness” and availed ourselves of better medical care we have not only seen a dramatic decrease in traditional infectious diseases such as rheumatic fever, hepatitis and tuberculosis, but over the same period of time we have witnessed a dramatic corresponding increase in “autoimmune diseases” such as Coeliac disease, Crohn’s disease, Multiple Sclerosis and Type I diabetes.

coeliac disease researchIn this trial which was supported by the Broad Medical Research Program in Los Angeles, twenty people with coeliac disease in remission were enrolled. They were inoculated with either hookworm or placebo, and all underwent a gluten challenge consisting of four pieces of white bread twice a day for 5 days after twenty weeks. They all had gastroscopies pre and post gluten challenge. The results have been positive and suggest the possibility of modulating the immune system with parasites is possible. Those who initially received the placebo have now been inoculated with hookworms and will undergo a repeat gluten challenge with biopsies.

Natalie is on the mend

Tuesday, April 20th, 2010

You may have seen the story of Natalie on the Channel 10 News on Sunday, 14 March.  Here is the full story…..

Living with coeliac diseaseAfter years of worry, Natalie was finally diagnosed with coeliac disease which is a serious condition affecting at least one in 100 children in Australia.  Sadly, four out of five children with the disease are not diagnosed.

Unfortunately, Natalie was so ill by this stage that she had to be hospitalised and fed through a tube.

“It was such a relief to know what was wrong with Natalie and to be able to do something about it,” said her Mum, Lisa.  “She was so ill when she was diagnosed that I couldn’t see that she was ever going to recover.

“But the turnaround in her health once she started treatment was immediate.  All her symptoms just disappeared and she started to eat again and put on weight.  She had so much energy it was like having a totally different child, it was as though someone had flicked a switch and she became alive again.  Her little personality started shining through for the first time in nearly two years.  I just wish we’d known what was wrong with her so much sooner.”

Paediatric Gastroenterologist, Associate Professor Don Cameron, is an adviser to The Coeliac Research Fund and The Coeliac Society.  He says that there is an urgent need to raise public awareness about coeliac disease in children, because although it is very common, it is often not diagnosed and can result in severe health complications in later life if it is not treated properly.

Associate Professor Cameron said that coeliac disease is nearly is nearly twice as prevalent as Type 1 juvenile diabetes1 and 25 times more common than cystic fibrosis2, but most people in Australia had never heard of it and diagnosis rates were very low.

“Coeliac disease affects at least one in 100 children in this country but four out of five are not diagnosed,” he said.  In fact, it is one of the most under diagnosed conditions of our time.  We call it ‘the hidden epidemic’ because most coeliacs are not diagnosed until they are adults and some are never diagnosed at all.

“But we need to put coeliac disease squarely in the public limelight because this is a very serious condition.  Not only can it cause very debilitating symptoms in children and hinder their growth and development, but if it is left untreated, it can also cause early onset osteoporosis, liver disease, infertility and cancer in later life,” he said.

Living with coeliac diseaseAssociate Professor Cameron said that coeliac disease typically starts in childhood between the ages of four and seven years old, although symptoms can present at any age, even in adulthood.

He urged parents to ring The Coeliac Awareness Hotline 1300 273 272 for more information if their child has any symptoms that could be due to coeliac disease.  These symptoms include unexplained bloating, diarrhoea and/or constipation, tummy pains, tiredness or lack of stamina, anaemia, mouth ulcers, failure to thrive or difficulty in concentrating.  “Sometimes, children with coeliac disease don’t have any obvious symptoms at all and just seem to be generally ‘out of sorts.’  Younger children in particular might just be clingy, grumpy or short tempered because they are feeling unwell and can’t explain why.”

Associate Professor Cameron said that children could not just ‘grow out of’ coeliac disease.  “This is a permanent condition which needs proper medical diagnosis and ongoing treatment,” he said.  “The good news is that diagnosis is simple and with the proper treatment, most children will start to thrive again very quickly and their risk of longer term health complications is minimised.

“Most importantly, we encourage parents not to diagnose their children themselves and not to eliminate gluten from their diet without medical advice.  Gluten is like a poison to coeliacs and parents need to learn how to manage their children’s diet very carefully under qualified medical supervision,” he said.

Associate Professor Cameron said that coeliac disease is hereditary and he urged anyone who has a relative in their family with the condition to arrange a coeliac test for themselves and their children.

Melbourne seminar attracts a crowd

Monday, April 19th, 2010

coeliac disease news and eventsThose who attended the Melbourne presentation breakfast by Professor Maki were delighted with the event.  Brenda Palmer, better known as to TV viewers as the actress who bounces to a boom box surprised guests with her humour at the start of the event.  The new children’s DVD was shown and many wanted copies which will be available soon.coeliac disease news and events

Professor Maki provided an in-depth presentation on how the Coeliac Society in Finland has supported coeliac disease awareness and diagnosis and indicated that coeliac disease is in fact on the increase and our understanding that 1 in 100 of the population has the condition may need to be revised.  Associate Professor Don Cameron and Professor Maki discussed the children’s DVD after the seminar.  Their association goes back many years to the 1980’s.

Plant enzyme supplementation for management of coeliac disease

Saturday, April 17th, 2010

The effect of plant enzyme supplementation on duodenal histology in coeliac patients maintaining a gluten free diet.

Help may well be on the way for the many coeliacs who, at some time or another, encounter difficulties with the choice of food for their gluten-free diet. We would like to evaluate an improved treatment for coeliac disease based on natural enzyme supplements. This work follows an earlier successful trial which was conducted under supervision of Professor Finlay Macrae.

Professor Finlay McCrae and his research team at Melbourne Health are investigating plant enzyme therapy in the management of coeliac disease. During a six week trial treatment, some volunteers will take treatment whilst others will be given a placebo. The changes in the gut will be monitored and villous atrophy assessed before and after the research period as well as the level of tTG in the blood.

Glutenon has been registered by the Australian Therapeutic Goods Administration as an enzyme supplement aid for gluten digestion. The registration number is AUST L 154806.  Glutenon is now being evaluated for management of coeliac disease.  It is hoped that Glutenon will be able to serve as a safeguard for people on a gluten-free diet, help people who are travelling or are exposed to foods of uncertain origin when going out with friends.

The trial is sponsored by the Coeliac Research Fund and has ethics approval by the RMH Human Research Ethics Committee.  For further information on the study contact Virginia Bird virginia.bird@mh.org.au.
