Celiac Disease Joshua Hoang
Definition • Celiac Disease is a digestive condition that is triggered by the intake of gluten which causes damage to the small intestine which results in the intestine inability to absorb nutrients [Bunch (2003)] • It is a tropical infection and is also known as celiac sprue or gluten-induced enteropathy. • Because the body’s own immune system causes the damage CD is classed as an autoimmune disorder • People with CD cannot tolerate gluten, a protein with wheat, rye, barley and possibly oats • Gluten is found mainly in foods but may also be found in products we use every day, such as medicines, and vitamins. CD = Celiac Disease http://semnceliacs.org/pics/nihceliac.gif
History • It was discovered in 250 A.D. by a Greek physician named Areteus of Cappadocia • He defined this disorder as “koiliakos” which meant suffering in the bowels • Francis Adams translated his writings from Greek to English during 1856 for the Sydenham society in England • Francis Adams called it Celiac Disease * bowels = intestines
Causes • The exact cause of CD is unknown • Partly genetic, strongly familial • Most forms of CD are inherited • If someone in your family has CD the chances are 5% to 15% that you may have it as well. • CD cannot be “caught” from another person and may occur at anytime in a person’s life • Sometimes the disease is triggered after surgery, pregnancy, childbirth, viral infections, or severe emotional stress. * Celiac Disease effects 1 in 133 people
Symptoms • The classic symptoms include: • Abdominal cramping • Chronic diarrhea • Anemia • Weight loss • Other symptoms may include: • Bone Pain • Depression • Fatigue • Painful Skin rashes • Delayed Growth * Celiac Disease is associated with a group on genes on Chromosome 6
Symptoms.. • The symptoms may occur as early as when a baby starts eating food • The symptoms may or may not occur in the digestive system. For example, one person might have diarrhea and abdominal pain while another person suffers through depression • A person with CD may or may not even experience any symptoms • If they do experience symptoms they may experience both physical symptoms as well as emotional symptoms http://www.celiac.org/images/img_faceofceliac.jpg
Effects • Normally the small intestine is lined with tiny, hair like projections called villi • The purpose of the villi is to slow the passage of food, and to allow food particles to be captured in among these finger-like villi so that the blood inside the villi can absorb the nutrients in the food http://www.celiac.org/images/img_villi.gif
Effects.. • When people with CD ingest gluten, the villi in the small intestine that are suppose to absorb nutrients from foods are damaged • This is due to an immunological reaction to gluten • Eventually, decreased absorption on nutrients can cause vitamin deficiencies that deprive your own brain peripheral nervous system, bones, liver and other organs of vital nourishment. http://www.bbc.co.uk/food/images/villi_280x90.jpg Here it shows the comparison between normal villi and damaged villi. http://www.vivo.colostate.edu/hbooks/pathphys/digestion/stomach/salmonella.jpg
Effects.. 1 3 2 Here you can see damaged villi Here you can see healthy villi in the small intestine Lastly, here is completely damaged villi http://www.netdoctor.co.uk/diseases/facts/glutenallergy.htm
Effects.. • Long term conditions if CD is left untreated: • Lymphoma and adenocarcinoma • These are cancers that can form in the small intestine • Osteoporosis • This is a condition where your bones become weak, brittle, and fragile • This is due to poor calcium absorption • Miscarriage and congenital malformation • Causes neural tube defects in babies • Due to nutrient absorption problems • Short Stature • results when childhood celiac disease prevents nutrient absorption during the years when nutrition is critical to a child’s normal growth and development http://www.soylabs.com/img/osteoporosis.jpg
Diagnosis • Because CD is hereditary, family members of a person with CD may need to be tested • Series of blood tests, x-rays, and a biopsy of the intestinal lining may be required • To confirm a diagnosis a doctor can microscopically examine a small portion of intestinal tissue to check any characteristic damage to the villi http://health.yahoo.com/media/mayoclinic/images/image_popup/intestinal_big.jpg http://www.gcarlson.com/images/villi.jpg
Treatment • Treatment is important because people with CD could develop more complications such as cancer, osteoporosis, and anemia • If CD is left untreated damage to the small intestine can be chronic and life threatening • Currently there is no cure for CD and it remains lifelong • The only treatment for CD is the lifelong adherence to a gluten free diet. • All grain products except rice must be removed from the diet indefinitely • If gluten is removed from the diet, the small intestine will start to heal and overall health improves • Complete healing and regrowth of the villi may take several months in younger people and as long as two to three years in older people. * The Gluten Diet is a lifelong commitment
Future Outlook / Research • A cure for CD is currently trying to be found • Removing all damaging grains from the diet is the most important measure you can take to become healthy. • Current research is under way in a effort to understand the pathogenesis (cause, development, and effects) of CD and is taking place worldwide. • This effort is fuelled by the appreciation that CD represents a unique example of an autoimmune disease • Therefore, scientists view CD as a model to tackle key questions on the pathogenic mechanisms involved in other autoimmune diseases
