Coeliac disease is associated with immune complex glomerulonephritis. [102] Anti-gliadin IgA antibodies are found also more commonly in patients with IgA Nephropathy. The paper finds a link between GSE and IgA Nephropathy, but not between CD and nephropathy. [103] Calcium oxalate correlates with severity of fat malabsorption in coeliac disease.
The complex (APC-DQ-gliadin) thus stimulates the gliadin specific T-cells to divide. These cells cause B-cells that recognize gliadin to proliferate. The B-cells mature into plasma cells producing anti-gliadin antibodies. This does not cause coeliac disease and is an unknown factor in idiopathic disease.
Of note, selective IgA deficiency can complicate the diagnosis of one such condition, celiac disease, as the deficiency masks the high levels of certain IgA antibodies usually seen in celiac disease. [18] As opposed to the related condition CVID, selective IgA deficiency is not associated with an increased risk of cancer. [19]
[27] [28] Additional testing has been conducted using IgA trans-glutaminase autoantibodies which has been identified as a specific and sensitive for the detection of celiac disease. [ 29 ] [ 30 ] Henoch–Schönlein purpura (HSP) is a systemic vasculitis caused by deposits of IgA and complement component 3 (C3) in small blood vessels.
The IgG antibody is similar to AGA IgA, but is found at higher levels in patients with the IgA-less phenotype. It is also associated with coeliac disease and non-celiac gluten sensitivity. [5] [6] [7] Anti-gliadin antibodies are frequently found with anti-transglutaminase antibodies.
Getting diagnosed can take years and symptoms can mimic other ailments, but celiac is a serious autoimmune disease that can lead to heart disease, bowel cancer and potential infertility in women.
The results of a 2017 study suggest that non-celiac gluten sensitivity may be a chronic disorder, as is the case with celiac disease. [ 42 ] For people with wheat allergy , the individual average is six years of gluten-free diet, excepting persons with anaphylaxis, for whom the diet is to be wheat-free for life.
