Celiac disease is primarily a disorder found in the Caucasian race. On clinical grounds the prior art prevalence was of the order of 1: 1000 to 1: 10000. There are certainly differences between rival electric food slicer countries, Germany has a low prevalence (below 0.5%) while both Sweden and Finland have a high prevalence of celiac disease. In some studies, and in selected age cohorts are currently 2-3% prevalence of celiac disease in neighboring rival electric food slicer countries. In screening studies can be found in Finland doubled celiac disease from 1980 to 2000. How does this relate in Norway is unknown, but the number who receive basic benefits of gluten free diet doubled from 2000 to 2008 (from about 6000 to about 12000). Since 2008, unfortunately NAV key has not been possible to provide figures on how many people rival electric food slicer get basic benefits. There is reason to believe that there are at least 40,000 people with celiac disease in Norway; Most of these are therefore undiagnosed.
Celiac disease occurs in all ages. In English material with 228 adult coeliacs got 19% diagnosed rival electric food slicer after age 60, many of whom had been in contact with doctors for a long time due to symptoms without getting diagnosed. Our impression is that many of these patients may have had a symptomatic but undiagnosed celiac disease as children, a clinical peaceful phase in adolescence and early adulthood before they get worse. rival electric food slicer In some cases, the small intestine mucosa from being normal to get sick in adulthood. In studies where large cohorts followed with regular rival electric food slicer blood tests, we see that "wraps" to positive serology can occur in any age.
We know little about what triggers celiac disease. Ingestion of gluten is an obvious factor. In Sweden in the 1980s were given gluten from ca. 6 months of age and in large doses, and this gave an epidemic of celiac disease among children under 2 years. Breast Milk Nutrition during introduction of gluten appears to protect against celiac disease. rival electric food slicer
Large studies published in recent years have shown a number of gene variants that are associated with celiac disease. Tissue genes HLA-DQ2 rival electric food slicer and -DQ8 is the most important genetic markers, but do not explain more than ca. 40% of heritability. So-called Genome Wide Assocation Studies (GWAS) have identified rival electric food slicer a number of other genes. Pt has identified 39 other genes, which in total contribute around 14% of the heritability. These genes are almost invariably genes that regulate the immune response. None of these non-HLA genes have so far some diagnostic role. Serological tests
Serological tests have an important place in celiac disease diagnosis. In children, one under certain circumstances the diagnosis of celiac disease based on serology alone. This is discussed rival electric food slicer elsewhere in this issue of NGF-again. There are three current serum tests, rival electric food slicer antibodies to gluten or subcomponents gliadin, the enzyme tissue transglutaminase 2 (TG2) and so-called deamidated gliadin peptides (DGP). It is most appropriate to analyze the IgA antibodies (intestinal own immunoglobulin). We are talking happily about IgA-AGA, IgA-TG2 and IgA-DGP. Analysis of IgG antibodies are particularly useful in patients with IgA deficiency.
IgA to gluten / gliadin is unlikely to make a celiac diagnosis. Most people have detectable IgA to gluten and gliadin, but typically occurs such antibodies rival electric food slicer in low titre. Values around and just above the cut-off limit correlates poorly rival electric food slicer with celiac disease. Unfortunately often used positive values of IgA to gluten / gliadin to conclude that the person has an intolerance to wheat, but this is not scientifically based. Measurement of anti-gliadin antibodies are being phased out in many laboratories.
It has long been known that most coeliacs have IgA antibodies against a connective tissue component of smooth muscle called endomysium, and it is shown that these antibodies recognize an enzyme called tissue transglutaminase (TG2). TG2 is expressed in many organs of the body. It is developed ELISA methods for detection of specific IgA antibodies. In clinical practice, these good measurements with reported specificity of 95% and more and sensitivity from 80 to 100% - but there is room for improvement. In routine clinical practice, tests are not as good as in many research materials. There are people whose values for IgA against TG2 is increased, but have normal tynntarmsbiopsier. We believe that many of these are on your way to developing a classic celiac disease. We call this "latent celiac disease".
Very recently, among others immunology laboratory at OUS begun to measure IgA-TG2 and IgG-DGP on all samples. It is uncertain whether this is a good strategy. You will surely capture more positive test, but the prevalence of celiac disease in individuals with negative IgA-TG2 and positive IgG-DGP is unknown. Several articles have discouraged such a combined testing routine.
