Study and Diagnose of Gluten Intolerance
12 261

Öz The prevalence of the celiac disease is different, for example in Italy 1 in 250 people suffer from celiac disease, Ireland 1 to 300, in USA 1 in 133 Americans. Recent studies have shown that the disease may be more common in Africa, South America and Asia. Celiac disease affects people in different ways. Signs may be in the digestive system or in other parts of the body. Since this damage caused by our body's immune system, the disease is classified as an immune disease. However, it is considered a disease of worst absorbed because nutrients are not absorbed. The disease is also known as celiac disease or no tropical celiac disease, or enteropathy by sensitivity to gluten. Our aim has been to diagnose the gluten intolerance in the child by immunological methods. Both IgA and IgG anti-gliadin antibodies (AGA) are detected in sera of patients with gluten sensitive enteropathy (celiac disease). IgG anti-gliadin antibodies are more sensitive but are less specific markers for disease compared with IgA class antibodies. IgA anti-gliadin antibodies are less sensitive but are more specific. In clinical trials, the IgA antibodies have a specificity of 97% but the sensitivity is only 71%. That means that, if a patient is IgA positive, there is a 97% probability that they have celiac disease. Conversely, if the patient is IgA negative, there is only a 71% probability that the patient is truly negative for celiac disease. Therefore, a positive result is a strong indication that the patient has the disease but a negative result does not necessarily mean that they do not have it. False positive results are rather uncommon but false negative results can occur.
