New developments in celiac disease

Celiac disease remains a challenge to the clinician and scientist. It is clearly more prevalent than was previously suspected. Much interest is seen in identifying the genetic factors, which predispose to disease and the environmental agents that can trigger it. Genome-wide searches have identified a number of chromosomal susceptibility loci. Specific gliadin epitopes are being analyzed. New diagnostic options include the tissue transglutaminase enzyme-linked immunosorbent assay. Neurologic disease and bone disease are intriguing complications of celiac disease and are gradually being defined.
