The NICE also recommend offering serological testing for coeliac disease in people with metabolic bone disease (reduced bone mineral density or osteomalacia), unexplained neurological disorders (such as peripheral neuropathy and ataxia), fertility problems or recurrent miscarriage, persistently raised liver enzymes with unknown cause, dental enamel defects and with diagnose of Down syndrome or Turner syndrome.Some evidence has found that early detection may decrease the risk of developing health complications, such as osteoporosis, anaemia, and certain types of cancer, neurological disorders, cardiovascular diseases, and reproductive problems. They thus recommend screening in people with certain health problems.Serology has been proposed as a screening measure, because the presence of antibodies would detect some previously undiagnosed cases of coeliac disease and prevent its complications in those people. However, serologic tests have high sensitivity only in people with total villous atrophy and have a very low ability to detect cases with partial villous atrophy or minor intestinal lesions. Testing for coeliac disease may be offered to those with commonly associated conditions. Treatment
Diet
At present, the only effective treatment is a lifelong gluten-free diet. No medication exists that prevents damage or prevents the body from attacking the gut when gluten is present. Strict adherence to the diet helps the intestines heal, leading to resolution of all symptoms in most cases and, depending on how soon the diet is begun, can also eliminate the heightened risk of osteoporosis and intestinal cancer and in some cases sterility. The diet can be cumbersome; failure to comply with the diet may cause relapse.
In the United Kingdom, the National Institute for Health and Clinical Excellence (NICE) does not (as of 2015) recommend the use of HLA typing to rule out coeliac disease outside of a specialist setting, for example, in children who are not having a biopsy, or in patients who already have limited gluten ingestion and opt not to have a gluten challenge. Endoscopy
An upper endoscopy with biopsy of the duodenum (beyond the duodenal bulb) or jejunum is performed to obtain multiple samples (four to eight) from the duodenum. Not all areas may be equally affected; if biopsies are taken from healthy bowel tissue, the result would be a false negative. Even in the same bioptic fragment, different degrees of
damage may be present.Most people with coeliac disease have a small intestine that appears to be normal on endoscopy before the biopsies are examined. However, five findings have been associated with high specificity for coeliac disease: scalloping of the small bowel folds (pictured), paucity in the folds, a mosaic pattern to the mucosa (described as a "cracked-mud" appearance), prominence of the submucosa blood vessels, and a nodular pattern to the mucosa.European guidelines suggest that in children and adolescents with symptoms compatible with coeliac disease, the diagnosis can be made without the need for intestinal biopsy if anti-tTG antibodies titres are very high (10 times the upper limit of normal).Until the 1970s, biopsies were obtained using metal capsules attached to a suction device. The capsule was swallowed and allowed to pass into the small intestine.
