ABSTRACT
Researched from immunologic and genetic point of view, 40 patients with Celiac Diseases confirmed and under-treatment. The results were compared with a group of 257 healthy people. The immunologic studies: leucocytes and lymphocytes in blood, the subpopulation of lymphocytes T and B, The immune-reaction studies of immunoglobulin Ig G, Ig M, Ig A and component C III complement didnt show difference between the comparative groups justified perhaps because the group of patients were under-treatment. In the antigen erythrocyte A B O and RHO (A), we can only in those assert that there is an increase of A and B group between the patients than who have O, and they were less exposed to get the disease. Between the histocompatibility antigen, the low presence of A9 B5 B7 BW16 antigen in Celiac patients could be a sign of protection against the disease, contrarily the presence of A1 B8 Dr3 Dr7 could indicate the high risk to get the disease. These finding confirm that the antigen group connected with the major System of histocompatibility, showed the susceptibility to suffer the disease.
