Jejunal lysozyme activity and the Paneth cell in coeliac disease.
نویسندگان
چکیده
The jejunal mucosa of patients with coeliac disease contains significantly fewer Paneth cells (PCC) per crypt (p less than 0.001) and tissue lysozyme activity (JLA) P less than 0.001) when compared with a group of subjects with normal jejunal mucosa. Neither PCC nor JLA return to normal with complete clinical recovery and otherwise complete histological recovery on a gluten free diet. There is a significant linear correlation between JLA and PCC suggesting that the Paneth cell is the principal source of jejunal lysozyme.

Enumeration of Paneth cells in coeliac disease: comparison of conventional light microscopy and immunofluorescence staining for lysozyme.
By conventional light microscopy, a reduced number of Paneth cells per intestinal crypt was found in the jejunal mucosa of patients with untreated or gluten-challenged coeliac disease as compared with histologically normal control specimens. A much better detection sensitivity was obtained when Paneth cells were counted by fluorescence microscopy after immunostaining for lysozyme with a rhodami...

Serum lysozyme activities were measured in 34 control subjects, 13 untreated adult coeliac patients, 21 adult coeliac patients on gluten-free diet, and eight coeliac patients with a histiocytic lymphoma. Serum lysozyme activities were raised in three untreated patients, three patients treated with a gluten-free diet, and in only two patients with coeliac disease and lymphoma. Serum lysozyme est...

Immunoglobulin-containing plasma cell densities in the jejunal mucosa and serum and jejunal fluid immunoglobulins have been measured in patients with adult coeliac disease and dermatitis herpetiformis with and without jejunal mucosal abnormality. Studies were performed in patients before and after treatment of the jejunal lesion.Total immunofluorescent plasma cells were increased in untreated a...

The in vitro secretion of immunoglobulins by small intestinal lymphocytes isolated from 47 patients with normal histology and 23 patients with treated and untreated coeliac disease was examined using an enzyme linked immunosorbent assay. In control patients, duodenal lymphocytes spontaneously secreted higher levels of IgM than jejunal lymphocytes (p less than 0.05). Significantly higher levels ...

Diamine oxidase plasma concentrations after treatment with heparin were measured and compared with the surface to volume ratio of jejunal biopsy samples assessed by a morphometric technique in patients with untreated and treated coeliac disease and in biopsied controls. As expected, enzyme activity was significantly lower in patients with untreated coeliac disease than in patients on a gluten-f...
