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, and since then it has become an invaluable resource to people worldwide who seek information about celiac disease and the gluten-free diet.
In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore! which was also another Internet first—it was the first gluten-free food site to offer a shopping cart-style interface, and the ability for people to order gluten-free products manufactured by many different companies at a single Web site.
I am also co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.

Celiac.com 01/29/2004 - A new cloning technique developed by Italian researchers may lead to more accurate diagnoses of celiac disease in borderline patients, including those who are asymptomatic. The technique screens for anti-tTG antibodies in the intestinal mucosa by utilizing a cloning process to amplify the antibodies, thus allowing for their detection even in cases where only minute amounts are present. The new technique is similar to that developed and long utilized by Dr. Kenneth Fine of Enterolab, in that both techniques look for the presence of antibodies in the intestinal mucosa rather than in the blood. The new technique also has the potential to easily screen large numbers of people, which, if the researchers are correct, will lead to a celiac disease diagnostic explosion, as those who are missed by current screening methods will be properly diagnosed. The number of celiacs who are missed using current screening techniques is a topic of debate, and Dr. Fines methods have demonstrated that "in normal people without specific symptoms or syndromes , the stool test is just under three times more likely to be positive than blood tests," as reported in the Winter 2004 edition of Scott-Free newsletter. It would be very interesting to see how many people test positive in a healthy population using this new technique.
Below is the abstract of the article:
One-step cloning of anti tissue transglutaminase scFv from subjects with celiac disease.
Celiac disease is characterized by intestinal mucosal injury and malabsorption precipitated by dietary exposure to gluten of some cereals with a prominent role being played by gliadins, specific antigenic determinants found in wheat gluten. Patients suffering from celiac disease have serum antibodies recognizing gliadin, as well as the Endomysial autoantigen tissue transglutaminase. Phage display antibody libraries have revealed ectopic production of anti-transglutaminase antibodies by intestinal lymphocytes with a biased use of the VH5 antibody gene family. Here we report a study on the pairing of VH and VL families in the antibodies to transglutaminase. Our results led to the construction of small phage display antibody libraries based on the amplification of the two genes in the VH5 family from intestinal lymphocytes. This method can be used for the rapid characterization of the anti-transglutaminase response in a potentially large number of subjects including asymptomatic patients whose serum antibodies may be undetectable.
