    Abstract:
    The objectives of this study were to verify comparatively clinical age reported antecedents and the morphological aspect of the intestinal mucosa in patients sensitive to gluten, hospitalised at IOMC ("Alfred Russescu" Hospital) in the last 7 years. Celiac disease is an inflammation most frequently affecting the proximal small intestine, depending on the presence of gluten in the diet, whose pathogenesis seems to be immunological in nature. 107 cases were divided in three groups following clinical manifestations types at hospitalisation time: typical digestive, untypical digestive and extra digestive manifestations. Intestinal biopsies, made with Crosby probe, in children aged between 1.3 and 8 years (one single case was diagnosed as late as at the age of 15), regardless of gender. Then we analysed morphologically (HE usual and PAS histochemical staining) and immunohistochemically (lymphocytes B, T with possible subtypes). The lesions were counted at the first biopsy according to the Marsh score. The immunohistochemical tests have indicated the prevalence of T lymphocytes (UCHL1, CD3, CD4, CD8, gamma-delta) both in the luminal epithelium with various degrees of aggression in lamina propria and also spread in stroma. B-lymphocytes (L26) are distributed prevalently nodular in stroma. In conclusion, it is CD4 T cells that are present in particular in the control of the gluten immune response in patients with Marsh I and Marsh III lesions.
