[Antireticulin antibodies and precipitating antibodies to food proteins in the sera of children with coeliac disease (author's transl)].
Sera from 41 children suffering with histologically proven coeliac disease and from 40 healthy control children were investigated for the presence of antireticulin antibodies and precipitating antibodies to a watery extract of wheat flour and to cow's milk. Antireticulin antibodies were demonstrated by means of indirect immunofluorescence using sections of fresh rat kidney as substrat. For the detection of precipitating antibodies a combination of electrophoresis and immunodiffusion was used. Serum antireticulin antibodies were found in 11/13 children (85%) with active coeliac disease, in 7/17 children (41%) with clinically and biochemically silent coeliac relapse and in 0/16 children with treated coeliac disease. Serum precipitating antibodies to wheat flour and cow's milk were found respectively in 3/13 children (23%) and 2/13 children (15%) with active coeliac disease and in 1/16 children (6%) with treated coeliac disease. Precipitating antibodies could not be detected in the sera of 17 patients with silent relapse of coeliac disease. In the sera of 40 controls neither antireticulin nor precipitating antibodies were detectable. The presence of antireticulin antibodies in serum did not correspond to the presence of serum precipitins to wheat flour and cow's milk. The significance of serum antireticulin antibodies for screening investigations and for follow-up studies is discussed.
