Celiac.com 12/20/2007 - Celiac disease is under-diagnosed because many celiac disease patients do not show classic gastrointestinal symptoms. Highly sensitive and specific serological tests have led to the diagnosis of celiac disease in patients for whom short stature may be the only obvious symptom. Researchers from Brazil and Italy have previously reported that celiac disease accounts for 1-5% of short stature in children.

Prevalence of celiac disease varies widely according to geographic location. Although epidemiological studies are lacking in India, celiac disease reporting has increased exponentially due to targeted screening and better serological tests. To better understand the relationship between short stature and celiac disease, researchers from the Endocrine Clinic of the Postgraduate Institute of Medical Education and Research in Chandigarh studied children referred for a work-up of short stature from January 2005 to December 2006.

Researchers enrolled 176 patients, half male and half female, who fit the criteria for short stature: height ≥ 2.5 standard deviations below the mean for chronological age, growth rate below the fifth percentile for chronological age, and height ≥ 2 standard deviations below mean for chronological age when corrected for mid-parental height. Most patients were 10-15 years old (mean age of 14.5).

Researchers took detailed histories and carried out clinical evaluations and screening tests. If they could find no endocrine cause for short stature or if diarrhea had been present for more than 3 months, researchers estimated IgA anti-tissue transglutaminase antibodies (anti-tTG) and performed an
