[3] [5] This newly proposed protocol has shown higher tolerability and compliance, and it has been calculated that its application in secondary-care gastrointestinal practice would identify celiac disease in 7% patients referred for suspected non-coeliac gluten sensitivity, while in the remaining 93% would confirm non-coeliac gluten sensitivity ...
[26] [22] It can take up to 12 years to receive a diagnosis from the onset of symptoms and the majority of those affected in most countries never receive it. [26] Several tests can be used. The level of symptoms may determine the order of the tests, but all tests lose their usefulness if the person is already eating a gluten-free diet.
Serology for anti-tTG antibodies has superseded older serological tests (anti-endomysium, anti-gliadin, and anti-reticulin) and has a strong sensitivity (99%) and specificity (>90%) for identifying celiac disease. Modern anti-tTG assays rely on a human recombinant protein as an antigen. [43]
Normally, up to 7 grams of fat can be malabsorbed in people consuming 100 grams of fat per day. In patients with diarrhea , up to 12 grams of fat may be malabsorbed since the presence of diarrhea interferes with fat absorption, even when the diarrhea is not due to fat malabsorption.
Thromboembolism is a well-described complication of IBD, with a clinical incidence of up to 6% and a three-fold higher risk of disease, [31] [32] and the Factor V Leiden mutation further increases the risk of venous thrombosis. [33] Recent studies describe the co-occurrence between coeliac disease, in which IBD is common in venous thrombosis ...
