Megjegyzések:In coeliac disease (CD), anti-tissue transglutaminase 2 immunoglobulin(Ig)A antibodies (anti-TG2) are produced and deposited in the intestine.PreventCD (www.preventcd.com) is a European multi-centre study, whichinvestigates the influence of infant nutrition and that of genetic,immunological and other environmental factors on the risk of developingCD. The aim of the current study was to evaluate the appearance ofintestinal anti-TG2 deposits in very early intestinal biopsies from at-riskinfants and their predictive value for villous atrophy. Sixty-five small bowelbiopsies, performed in 62 children, were investigated for the presenceof intestinal anti-TG2 extracellular IgA deposits by using doubleimmunofluorescence. The biopsies were performed in the presence ofelevated serum levels of CD-associated antibodies and/or symptomssuggesting disease. Deposits of anti-TG2 IgA were present in 53 of 53 CDpatients and three of three potential CD patients. In potential CD patients,mucosal deposits showed a patchy distribution characterized by some areascompletely negative, whereas active CD patients had uniformly present andevident mucosal deposits. Only one of six patients without CD (negative forserum anti-TG2 and with normal mucosa) had intestinal deposits with apatchy distribution and a weak staining. Two of the 53 CD patients receiveda definitive diagnosis of CD after a second or third biopsy; mucosal depositsof anti-TG2 IgA were evaluated in all samples. Before developing villous atrophy, both patients had anti-TG2 deposits in normal mucosalarchitecture, antibodies in one patient being absent in serum. We demonstrated that in CD the intestinal deposits of anti-TG2 are a constant presence and appear very early in the natural history of disease.
