IgA and IgG reticulin antibodies in coeliac and non-coeliac patients
Abstract:
Using indirect immunofluorescence, comparisons were made of patterns of staining of five tissue substrates with 28 RI reticulin antibody-positive coeliac sera, and 23 RI reticulin antibody-positive non-coeliac sera. IgA and IgG fluorescein conjugates were used separately. IgA antibodies were seen in 22 coeliac patients (78%) compared with three non-coeliacs (13%). Concomitant sinusoidal fluorescence (RS pattern) was seen more frequently with the non-coeliac (60.9%) than with the coeliac sera (10.7%). Such differences may help to distinguish those patients who should have a jejunal biopsy when using the reticulin antibody as a screening test for coeliac disease.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
