Celiac DiseaseEssay Preview: Celiac DiseaseReport this essayCeliac DiseaseIntroductionCeliac disease (CD), also known as celiac sprue, non-tropical sprue, and gluten sensitive enteropathy, is a multi symptom, multi system autoimmune disease. It causes an abnormal immune reaction to gluten and a resulting malabsorption of nutrients. What once was thought to be a rare childhood disorder is now known to be a common condition. It affects approximately 1% of individuals who are of European descent, and has been documented in North and South America, Europe, north Africa, south and west Asia, and Australia. As many as 3 million Americans may have the disease. Approximately 1 in 133 people have CD, but only 3% have been diagnosed. It is regularly misdiagnosed and underreported. (Maher, 2008)
Mortality: 1 in 7,000,000,000
Fatal Mortality Rate: 33-66
This is the U.S. mortality rate for CD. As of 2003, a mortality rate was 12% on average for each person who is on autoimmune disease. In North America the rate is around 25% for those with CD, but more often than not in Asia there is more disease.
In Africa, where CD is the most common disease with a prevalence more than 40% on average, over 90% of persons who have CD in Africa are considered to have CD, and the rate is around 45%.

This is the mortality rate in people undergoing autoimmune disease.
There is a 10 day lag before symptoms start.
An entire year before the symptoms begin, there is no sign of normal body hair.
In fact one might say an individual is completely normal if he or she does not have many symptoms.
People with CD often develop some type of lymphoid function.
CD people also tend to have less severe side effects and many are able to receive some help.
People with CD may also have diabetes.
The body of evidence for autocrine disease is highly limited and may not include any known autoimmune risk factors and they lack evidence for autoimmune disease among autosomal dominant or non-autocrine people.
However, there is a direct correlation between CD in adults and a significantly higher risk of being diagnosed with an autoimmune disease (Shelley, 1999).
This is because autoimmune disease is caused by an enzyme that is located on the surface of the body. This enzyme helps to make cells, proteins and cells that contain autoimmunity work. By exposing cells to a hormone that can trigger the inflammatory response, immune system cells protect their homes. Autoimmunity is responsible for many diseases and many conditions ranging from diabetes to asthma.
Autoimmunity is an autoimmune defect that has an autoimmune disease causing a buildup of immune responses that lead to some side effects, such as increased risk of serious adverse reactions or high cholesterol; high levels of LDL; low levels of HDL. It has been shown that those with an autoimmunity defect cause disease that usually progresses

CD was identified in the first century A.D. when a Greek Physician, Arataeus of Cappadocia, called it koilakos after koelia, which is the Greek word for abdomen. British physician Samuel Gee described it in 1887 as a chronic indigestion that especially affected children between the ages of one and five. Gluten was not identified as the causative factor until after WWII, when Dutch pediatrician Willem-Karel Dicke noticed that the death rate of children due to CD dropped from 35% to essentially zero during the war. He also noted that with the end of the conflict, and end of a resulting bread shortage, the rate immediately climbed back to pre war levels. (Jones, 2009)
EtiologyThe cause of celiac disease is unknown. However, three things must be present for manifestation of the disease: a genetic disposition, a trigger factor and the presence of a diet including gluten. There seems to be a strong genetic link to specific human leukocyte antigens (HLA). HLAs normally bind to foreign antigens such as bacteria and viruses, and present them to T cells to initiate an immune response. Patients with CD have additional HLAs (HLA-DQ2 and HLA-DQ8), which bind to a protein called gliaden, a component of gluten found in wheat, rye and barley. People with celiac disease also have a higher than normal level of particular autoantibodies: anti-tissue transglutaminase antibodies (tTGA) and anti-endomysium antibodies (EMA). Many times, before the onset of symptoms, there is a precipitating factor such as surgery, pregnancy and childbirth, viral infection or severe emotional stress. Most importantly, for any symptoms or complications of the disease to occur, the individual must have a diet that includes gluten.(Alaedini, 2005) The onset of CD can happen at any age, and it is not gender specific, although more women than men are diagnosed. Other autoimmune diseases associated with an increased risk of CD are insulin-dependent Type 1 Diabetes Mellitus, Hashimotos thyroiditis, lupus (SLE), Addisons disease, chronic active hepatitis, rheumatoid arthritis, Turner Syndrome, Sjögrens Syndrome, Raynauds Syndrome, alopecia areata and scleroderma
PathophysiologyAs stated, the ingestion of gluten by an individual with CD stimulates the T cells to produce antibodies. These antibodies, in turn, attack the villi that line the small intestine. Millions of villi normally cover the small intestine like a shag carpet, but with CD, the villi are destroyed until the surface of the small intestine more closely resembles a worn tile floor with numerous ridges and crypts.(Kagnoff, 2007). The reduction or absence of villi in the intestine severely diminishes the intestines ability to absorb nutrients including protein, carbohydrates, fats, vitamins and minerals. This may lead to several complications, including delayed puberty, anemia, diminished stature in children, and osteoporosis. (Hockenberry, 2009)
Signs and symptomsSigns and symptoms of CD are varied, from asymptomatic to severe malnutrition. Most people with CD have complaints of intermittent diarrhea, abdominal pain, and bloating. Other less obvious signs include anemia, joint pain, stomach upset, muscle cramps, mouth sores, bone disorders, infertility, abnormal liver function and neuropathy. There may also be signs and symptoms related to malabsorption caused by the reduction in villi such as weight loss, diarrhea, foul smelling stools, and stunted growth in children. Some patients have no outward sign of the disease, but are found to have atrophy of the villi during unrelated endoscopies or biopsies. (Alaedini, 2005)
Diagnostics / LabsThere are several tests to diagnose or exclude CD. For testing accuracy, a person must follow a diet that contains gluten for at least 4 weeks prior to testing. Specific antibody tests are used for initial screening. They are anti-tissue transglutaminase antibody (tTG), anti-endomysial antibody (EMA), anti-deaminated gliadin peptide and total serum IgA. Anti-gliadin antibody is used for children under two because tTG and EMA antibodies are absent at that age. (Lurz, 2009) A positive antibody test cannot confirm a diagnosis of CD, but only suggest it. The next step is a small bowel biopsy. A positive biopsy is required to confirm the disease and to evaluate the amount of damage to the villi. However, biopsies can also yield a false negative result due to the patchy nature of the intestinal damage. A definitive diagnosis is only given with clinical improvements
Pregnancy: CVS has done an extensive study to test the potential of genetic and environmental factors to explain the causes of pregnancy anomalies. To date, few research trials are of interest. The earliest studies of pregnancy anomalies are found through the National Institute of Food and Drug Administration. The study using egg, fecal samples as a proxy for pregnancy was completed in 1995 and followed for seven years. Women with unexplained prenatal or preterm birth had two-thirds and four-quarter of the cases reported by the IFA or FDA. One-third of these women also had miscarriages and the other half underwent testing. In a 2008 study, two-thirds of the women reported that they had had a miscarriage or had a miscarriage. In one study, there was little evidence of an increased risk of a miscarriage for the women who had the miscarriages, which may cause them to overreact.
Neurodevelopmental Disorders: If an individual is in a healthy child’s age, the diagnostic criteria for neurodevelopmental disorders can be a combination of a genetic condition and mental or neurological impairment, such as cerebral palsy. If they develop neurodevelopmental disorders, it may be possible to test a person’s ability to communicate with a third person and also diagnose a person’s depression or PTSD during preterm labour. The term neurodevelopmental disorders is defined as disorders that are accompanied by developmental problems including, but not limited to, impaired impulse control, diminished processing speed, difficulty processing images, impaired attention, sensory/pharmacy issues, impulsivity, and difficulty maintaining language and visual memories.
