Can Better Biopsy Practices Improve Celiac Diagnosis in Children?

Celiac.com 03/27/2015 - Researchers don't have any solid idea about how common cases of seronegative celiac disease might be, but many feel strongly that rates of seronegative celiac disease are underestimated in children, and may result in misdiagnosis of celiac cases.

Photo: CC--Ari BronsteinOne team of researchers wondered if an emphasis on "serology-led" diagnosis might be contributing to a low rate of celiac disease diagnosed in children from the United States. That research team included Deborah L. Preston and Yoram Elitsur, and they recently set out to investigate the rate of celiac disease after upper endoscopy (EGD) with no prior positive celiac serology compared with the rate of celiac disease followed by positive serology.

The team conducted a retrospective review of that charts of all of the first diagnostic EGDs in children (2009–2013). They split the patients with confirmed celiac disease into 4 groups: group A, positive EGD/positive serology (histology-led diagnosis); group B, positive serology/positive histology (serology-led diagnosis); group C, positive histology followed by negative serology (control 1); and group D, positive serology followed by negative histology (control 2).

The team reviewed a total of 761 upper endoscopic charts. They confirmed 15 children with celiac disease, for a rate of 1.97%. Group A and group B had similar demographic data or clinical symptoms, and similar rates of celiac disease between histology-led celiac diagnosis (group A) and serology-led celiac diagnosis (group B) (1.18% vs 0.79%, P = 0.273).

This study showed that endoscopy-led diagnosis and serology-led diagnosis found celiac disease at similar rates.

This finding suggests that better diagnosis of celiac disease in children requires performing an adequate number of intestinal biopsies in every diagnostic upper endoscopic procedure.

My son was diagnosed as celiac only after the biopsy, grade IV. The blood test we did before was sero negative. We would have known if it was not for the biopsy.

Did you eat the corn right at the farm? Was it removed from the husk and roasted or was it washed? I cannot tolerate GMO corn and get very sick with ANY pesticides, especially Round Up. Something to think about.

Restaurant dining and the staff knowledge is frustrating. I already know that they know nothing, lol. They think they do - but they don't. They think that if they aren't dumping flour on it, then it must be gluten free. I have a couple places in town that I eat, and get the same thing. About...

How did you transition from coloring to natural gray?? It seems like a mystery to me! (Sorry OT)

Sounds like food poisoning. Is this the same or similar reaction you get to CC? Did any of your family have it too? Who cooked it? Did you ask them what they used to prepare it? Was it cooked on a grill alone or in the husk? What else was cooked at the same time?
