Serum immunoglobulins and lymphocyte transformation studies in coeliac disease.

Intestinal immunoglobulins in children with coeliac disease.

The numbers of immunoglobulin-containing cells in jejunal biopsy specimens of 19 children with active coeliac disease aged 0.5 to 16.5 years were studied by direct immunofluorescence. Intestinal juice immunoglobulins were measured in 14 of these patients. The number of IgA-containing cells was twice and the number of IgM-containing cells 2.5 times that of age-matched controls. There were also m...

Immunoglobulins and dietary protein antibodies in childhood coeliac disease.

Twenty-four children with coeliac disease were compared with a control group, comprising 17 children with a variety of gastroenterological disorders, with respect to serum immunoglobulins and dietary protein antibodies. Elevated levels of IgA and abnormally low levels of IgM were demonstrated in one third of the coeliac patients. Antibodies to at least one of eight dietary proteins were found i...

Lymphocyte transformation and chromosome studies in Hodgkin's disease.

T-lymphocyte subsets in adult coeliac disease.

1. As a defect of suppressor function has been hypothesized in the pathogenesis of coeliac disease, we measured, by monoclonal antibodies, the inducer/suppressor T-cell ratio in adult coeliac disease. 2. No statistical difference was observed between coeliac patients and healthy controls, irrespective of treatment and HLA status. 3. These results do not show an imbalance in the inducer/suppress...

Lymphocyte subpopulations in adult coeliac disease.

Rosetting techniques were used to estimate T and B cell subpopulations in the peripheral blood in patients with treated and untreated adult coeliac disease and in control subjects. In patients with untreated coeliac disease, T cell numbers were significantly lower than in controls or treated patients, although there was no difference in total lymphocyte counts. There was no significant differen...
