[Methods of screening for adult celiac disease in patients attending ambulatory care service in immunology].

Introduction: Coeliac disease (gluten sensitive enteropathy) is a very frequent disease appearing in variegated clinical form. In the last decade--concerning the immunogenetic and immunopathological aspects of the disease many of new recognition came to alight.

Aim: As the disease can lay hidden in its non classical manifesting form for a very long time, authors wished to study the efficacy of screening, which may be introduced for patients attending immunological outpatient care service.

Patients, Methods And Results: In the frame of nation-wide patient care, out of the 200 potential patients sent for immunological check up, various form of coeliac disease was diagnosed in 20 cases. Among these cases there are two--presented for the first time--which are connected to bone marrow transplantation. Based on the immunogenetics and autoantibody serology as well as on small intestine biopsies the following conclusions were made.

Conclusion: 1. Coeliac disease in Hungary is very frequent. Hidden disease should be considered first of all in cases of malabsorption symptoms. 2. Demonstration of autoantibodies on wide-scale palette helps to state the diagnosis based on the systematic auto-immune disease connection. 3. Study of Human Leukocyte Antigen allotype (HLA-DQA1*0501/DQBI*02) applied as marker can considerably support the suspicion of disease. 4. Histology test of the small intestine cannot be omitted.
