Background & aims: Celiac disease is characterized by disturbed jejunal crypt-villus axis biology with immunoglobulin (Ig) A deposits underlining the epithelium. The aim of this study was to test whether celiac disease serum IgA (reticulin/endomysial autoantibodies) interferes with the mesenchymal-epithelial cell cross-talk.When celiac disease (CD) is suspected, guidelines recommend use of both a tissue transglutaminase (TTG) immunoglobulin A (IgA) test and a total serum IgA test (if selective IgA deficiency has not previously been ruled out). If selective IgA deficiency is present, serologies should focus on CD-specific IgG antibodies.IgA-deficient people have a tendency to develop infections and disorders of the gut, such as malabsorption, lactose intolerance, celiac disease, and ulcerative colitis [25, 33]. Risk of Autoimmune Diseases. Patients with selective IgA deficiency (undetectable IgA but normal IgG and IgM levels) have a 10 to 20 times higher risk of celiac disease .Immunoglobulin A, Qn, Serum. Optimal Result: 87 - 352 mg/dL. Interpret your laboratory results now. Immunoglobulin A (IgA), one of the five primary immunoglobulins, plays a pivotal role in mucosal homeostasis in the gastrointestinal, respiratory, and genitourinary tracts, functioning as the dominant antibody of immunity in this role.IgA nephropathy is a chronic kidney disease. It progresses over 10 to 20 years, and it can lead to end-stage renal disease. It is caused by deposits of the protein immunoglobulin A (IgA) inside the filters (glomeruli) in the kidney. These glomeruli normally filter waste and excess water from the blood and send them to the bladder as urine.

The serum samples were stored at −20°C until they were analyzed for additional CoD-specific antibodies. The patients were divided into three groups according to their serum IgA concentrations and EmA results (Fig. (Fig.1). 1).
