Refractory sprue.
Celiac disease is a T cell-mediated disorder that results from intolerance to gluten. The major cause of failure to respond to a gluten-free diet is continuing gluten ingestion. In poorly responsive patients diagnosis of refractory sprue can be established after exclusion of a limited number of conditions. Refractory sprue may occur after an initial response to the diet or without evidence of preexisting celiac disease. The detection of aberrant, clonally expanded, intraepithelial lymphocytes has led to better definition and classification of patients with refractory sprue. Only a few series of patients with well-characterized refractory sprue have been reported in the literature. The prognosis is poor, though some patients respond to corticosteroids and immunosuppressive agents. The presence of an aberrant clonal intraepithelial T-cell population has led to the designation of refractory sprue as a cryptic intestinal T-cell lymphoma.
