DEVELOPMENT OF INCREASED EPITHELIAL PERMEABILITY SYNDROME IN RHEUMATOLOGICAL PATIENTS

Assessment of the integrity of the intestinal barrier using morphological examination of biopsies of the mucous membrane (CO) of various parts of the gastrointestinal tract with subsequent staining with hematoxylin and eosin, which allows to identify ulcerative defects, erosion of CO, to assess the density of cellular infiltrate and its composition, as well as the degree of atrophy, which can serve as indirect signs of altered permeability .
