The enteropathy of celiac disease

Celiac disease with pulmonary haemosiderosis and cardiomyopathy

Celiac disease or pulmonary haemosiderosis can be associated with several distinguished conditions. Pulmonary haemosiderosis is a rare, severe and fatal disease characterised by recurrent episodes of alveolar haemorrhage, haemoptysis and anaemia. Association of pulmonary haemosiderosis and celiac disease is extremely rare. We describe a case of celiac disease presented with dilated cardiomyopathy and pulmonary haemosiderosis without gastrointestinal symptoms of celiac disease. In addition, vitamin A deficiency was detected. This case suggests that celiac disease should be considered in patients with cardiomyopathy and/or pulmonary haemosiderosis regardless of the intestinal symptoms of celiac disease.

Proximal small-bowel mucosal villous intraepithelial lymphocytes

Small-bowel biopsies are routinely obtained from adult patients as a screening tool to evaluate the possibility of gluten sensitivity (GS). Previous morphological criteria of GS including completely flattened villi are usually absent. In the context of screening for GS, an altered distribution density pattern of villous intraepithelial lymphocytes (IELs) is probably the most sensitive morphological feature to suggest the possibility of GS and prompt the initiation of further medical evaluation. Altered villous IEL density distribution is a more sensitive screening feature than villous IEL counts. With increased small-bowel GS screening biopsies, occasional adults without GS with complete villous flattening and numerous villous IELs are encountered. These patients are usually incorrectly diagnosed with GS. However, they do not respond to a gluten-free diet and slowly improve over months.
