In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I founded The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.
Karoly Horvath, M.D., Ph.D., Associate Professor of Pediatrics; Director, Peds GI & Nutrition Laboratory; University of Maryland at Baltimore: There are age dependent changes in several blood parameters during childhood. It is well known that immunoglobulin levels depend on the age of children. E.g. the IgA class immunoglobulins reach the adult level only by 16 years of age, and the blood level of IgA immunoglobulins is only 1/5th of adult value below two years of age. A large study from Europe (Brgin-Wollf et al. Arch Dis Child 1991;66:941-947) showed that the endomysium antibody test is less specific and sensitive in children below two years of age. They found that the sensitivity of the EmA test decreased from 98% to 88% in children younger than 2 years of age. It means that 12% of their patients with celiac disease, who were younger than two years of age, did not have an increase in their endomysium antibody levels.
