Celiac Sprue

The celiac lesion in the proximal small intestine was first described by Paulley in 1954.

It was learned that celiac disease and adult non- tropical sprue share many of the same features

These classic findings are:

mucosal inflammation

crypt hyperplasia

villous atrophy

Many studies have also shown high prevalence

1:152 in the Belfast MONICA project evaluating 1,823 participants 1

1:256 was noted in a screening study of 1866 Swedish blood donors 2

1:99 in a study of 3654 Finnish students 3

1:96 in a study of 3188 Italian school children 4

Celiac disease as an immune disorder that is triggered by an environmental agent (the gliadin component of gluten) in genetically predisposed individuals

Genetic factors play an important role- there is significantly increased risk of celiac among family members

A close association with the HLA-DQ2 and/or DQ8 gene locus has been recognized

HLA-DQ2 is found in 98% of celiac patients from Northern Europe.

However, ~25% of “normal” individuals in this population will also demonstrate HLA-DQ2
