A patient is reported with mast cell infiltration of the small intestine in the absence of the skin involvement characteristic of mast cell disease. She also had subtotal villous atrophy responsive to a gluten-free diet. Criteria for diagnosing mast cell disease of the small intestine are proposed. The literature of small intestinal mast cell disease is reviewed and the relationship to coeliac ...

Refractory celiac disease (RCD) is a rare but life-threatening complication of celiac disease (CD), and only 1 pediatric case has been reported. We report a case of a 14-year-old girl with CD presenting with persistent symptoms and positive tissue celiac-specific antibodies despite a gluten-free diet. Push enteroscopy showed jejunal scalloping and partial villous atrophy on histology. She was d...

A 42 year old man presented with gluten-responsive coeliac disease and secondary pancreatic insufficiency. Subsequently his symptoms relapsed and repeat small intestinal biopsy showed villous atrophy and infiltration by leukaemic cells, despite continuation of a gluten-free diet. Serious causes of relapse and non-responsiveness in coeliac disease include enteropathy-associated T-cell lymphoma, ...

Enterokinase was measured in peroral intestinal biopsies showing normal histology and in those from untreated coeliac patients which showed gross villous atrophy. There was no significant difference in the specific activity of enterokinase between these two groups. These results do not support the recent hypothesis that enterokinase is a brush border enzyme, but would be consistent with the ide...

This study aimed to investigate the degree of colonic metaplasia in ileo - anal pouches. Biopsy specimens from 25 patients with functioning pouches, eight of whom had pouchitis, were studied using routine histology, mucosal morphometry, mucin histochemistry, and immunoperoxidase staining with monoclonal antibodies directed towards a 40kD colonic protein and a small bowel specific disaccharidase...
